Title: UK RHD LS1 8.8 FD Gunnytron's build thread
Post by: Gunnytron on August 04, 2012, 01:01:08 PM
Finally I have decided to get my butt in gear and start a build thread.

I have spent most of my time gathering parts and slowly removing the rotary out of my donor car so I have a bit of catching up to do.

My donor car is an automatic 94 X-Type in white with glass sunroof.

The motor is a 2000/1 LS1 45K with:
220 3.90 Bore Trickflow CNC heads
YT Ultra light Rockers
7.50 TFS pushrods
Custom Camshaft 219/215 .604/.601 115 + 3
ARP Head Bolts (Reusable for Boost)
Underdrive pulley
All emissions removed
Vengeance Racing ported FAST 90 intake manifold
Nick Williams 90mm Throttle Body

The guy I bought it off had intended to go turbo so the parts are setup for that. I have no intention of going that bonkers so for the moment I will see what power it kicks out as is. I may go for a lumpy cam and mill the heads at a later date.

I will be running power steering but no aircon. I am also intending to run mafless.

The box has a uprated internals (not sure what), Textralia OZ700 clutch and flywheel

I have gone for mostly Samberg stuff though for the rear I am holding out for a guy here in the UK to finish developing his Cobra rear diff mount.

I had some time off between moving flats so went to my mates workshop and made use of their skills and facilities.

Got my new camber bolts welded. They made the Samberg plates flush with the outer rather than the inner surface which meant they were sitting a little to proud of the groves on the subframe so I stuck them in a lathe and shaved the backs off a little.

(https://i.imgur.com/JPl9Qug.jpg)

I also got the Monaro master cylinder mounted to the clutch pedal. Whilst doing this I also bead blasted all the pedals and gave them a coat of Hammerite.

To get the master to fit properly I ground away some of the inner frame. I had to be careful to make sure the rubber boot wasn't going to rub on the frame.

(https://i.imgur.com/eUlPNoa.jpg)

(https://i.imgur.com/rQaUMkG.jpg)

I shaved the side off a bolt to get it to sit where I wanted
(https://i.imgur.com/Ksh3XP9.jpg)

Instead of doing any welding I just threaded the gnarly end of the bar with a 1/4" thread (I think)
(https://i.imgur.com/9xiHqsB.jpg)

If I hadn't already done the work I would have followed zeeshan's lead here http://www.norotors.com/index.php?topic=11999.0 (http://www.norotors.com/index.php?topic=11999.0)
That would involve more time and money though so I am sticking with what I have and keeping fingers crossed.

Fuel fittings. Think I have most of them but may need a few more. I started making an illustrated chart of the system setup I decided to go with. I will post it up when it's finished. I spent quite some time time trying to visualise where and what parts to get so hopefully it will helps others.

Whilst sourcing parts I have found it very hard to resist buying stuff that I want rather than what I need. Here is an example of a moment of weakness. A new GTO shifter with textured leather and black boot with black stitching

Post by: Gunnytron on August 04, 2012, 01:46:46 PM
I still have several major components to source:

Wiring loom (probably go with an ebay job)
Sound proofing
Heat shielding
Fuel pump (going Bosch 044)
Gauges (would like to go with Jordan innovations' autometer but that is straying into the "stuff i'd like rather than "stuff I need" pile http://www.norotors.com/index.php?topic=12610.0 (http://www.norotors.com/index.php?topic=12610.0))
Intake (going to try and make a Samberg style over the rad setup for my hinson single fan rad)
Power steering lines (not sure about this yet. If i can I will go with a Pez style setup but sourced over here)

My list of jobs to do next:

Remove FD subframe
Remove Auto box and propshaft
Remove auto diff and driveshafts
Cut gear lever hole

Doing some of these jobs will take a little planning as my garage isn't very big so once one end of the suspension is off I won't be able to move the car easily.

Yep going to be interested in this thread. I'm in my third year of owning my RHD FD after the conversion.

Jealous of the parts though especially if the T56 is uprated as mine is the worst part of my conversion. Doesn't like high rev shifts very much.

I have stumbled across a few threads about WOT shift problems. I vaguely recall the corvette people fitting a shim on one of the bolts or something. Might also be master cylinder issue possibly???

Another bridge to cross if/when I get tO it.

Well today has turned into a day of not so good discoveries.

I got up early all enthusiastic, went to the recycling centre to ditch an old downpipe, get rid of some oil and ditch that rank spoiler.

Then it all went wrong. I had planned to get stuck in and remove the diff and axles today but my first problem was this...

A pond in the wheel well.
(https://i.imgur.com/fwIOMgO.jpg)

I tried using my new wiggle syphon, but that was rubbish so resorted to the old sucking technique. That worked but I was slightly unnerved to see lots of bird feathers in the water. I may have just poisoned myself :)

Bit cleaner but a little smelly
(https://i.imgur.com/wZzmLFS.jpg)

Whilst I had the boot open I noticed a rogue wire going through the bodywork. Not sure what is going on here. Either its a terribly lazy fix or the fog light has been wired in to the bumper light (there is no fog under the bumper)
(https://i.imgur.com/j18PNPD.jpg)

To top that off I discovered that I had made a school boy error. I never thought to check if I had the socket for the wheel nuts.

I had nothing to undo this. Not sure if it is a standard mazda pattern but it pretty much ended my days work on the car.
(https://i.imgur.com/IaWzymA.jpg)

So, the only progress I made today was draining the diff fluid.

You win some you loose some :)

Post by: Gunnytron on August 05, 2012, 08:58:59 AM
HAHA, panic over. I suddenly remembered that I found an old socket covered in oil and melted sweet in the glovebox.

Luckily I hadn't thrown it out as it turns out its the wheel nut socket I need. Phew.

Got the car jacked up and the wheels of with the intention of getting the diff out.

Now I don't know if I am doing something wrong but I could get the f****n shafts out the diff. I was putting all my force on the prybar trying to break them apart but the gits won't budge.

Post by: radiomike on August 05, 2012, 06:31:59 PM
You are making life difficult for yourself by trying to remove the diff with the subframe in the car, one brake pipe, 4 bolts and 4 nuts will drop the entire subframe giving easy access to the fuel lines too.  Use 2 prybars at 180 degrees and 'walk' the joints free, they are only held in by a snap ring that sits in a groove. 

If you have a pre 1994 car you may need to weld a couple of brackets to the subframe which is much easier with it removed.

The outer CVs can be a PITA to remove/re-build and need a bit of patience.  Have you managed to find a pair of Cobra inner CVs?
Title: Re: UK LS1 FD Gunnytron's build thread
Post by: Gunnytron on August 06, 2012, 02:55:11 AM
I was hoping to avoid dropping the subframe at this stage as all I wanted to do was drop the diff so I can sell it.

As I don't have the rear diff mount yet I would have to bolt the subframe back in again after I took the diff out so that I can move the car.

I have no idea when the diff mount I want to use will be available. If it is much longer I will have to go the Samberg route. Here's the link to the mount http://www.fduk.org/forum/showthread.php?t=27795&highlight=Cobra (http://www.fduk.org/forum/showthread.php?t=27795&highlight=Cobra)

I have the DSS axle kit already. As for welding, I would have to check. If the UK mount ever gets finished I will have to send him my subframe.

Well, I don't know what all the fuss was about. This evening I went to the garage with the intention of getting the exhaust back box unbolted and gave the drive shafts another go.

Low and behold they popped off with ease. And that was with the exhaust in the way too. The only things I did different were that I was right on my back underneath with a 20mm pry bar instead of a 60mm. I also got it right in the thin gap between the shaft and the diff (I didn't do this before as I was worried about damaging it). Anyway, that combo worked a treat.

Of coarse, I couldn't get the f***n exhaust bolts off. You win some you loose some :)

I am not looking forward to the hub nuts either.

Post by: Gunnytron on August 13, 2012, 02:34:41 PM
I managed to get both driveshafts off today. The hub nuts came off easily enough though on one side I had to wedge a screwdriver between the disk and calliper to stop the wheel turning.

One of the drive shafts came out of the hub easily too. The other one is going to need a little more effort.

Sometimes you just need the right tool for the job.

Fuel pump turned up today. I initially intended to go with the Aeromotive 340 stealth but after doing a bit of reading decided that the Bosch 044 would be better due to its higher flow rates at higher pressures.

Made some decent progress this weekend.

I was about to give up as the heat was getting to me and one particular nut was giving me grief. Luckily a neighbor lent me his grinder so thanks to him I managed to get the exhaust, powerplant frame, driveshaft and rear diff off.

Now there's a lot more room under the car, but a lot less on my garage floor.

I had a feel of the rear wheel hub bearings and one has a very slight click in it so I may have to replace those whilst they are off.

Started on my axle kit today. This thread http://www.rx7club.com/3rd-generation-specific-1993-2002-16/300m-axle-conversion-writeup-550905/ (http://www.rx7club.com/3rd-generation-specific-1993-2002-16/300m-axle-conversion-writeup-550905/) has some good info on getting the drive shafts apart.

STAGE - 1

1 - Take all the clamping bands off the boots. I just pushed and twisted a small screw driver in the joins
2 - Remove the rubber boot from the hub end. I used WD40 to spray the axle so the boot would slide easily
3 - The link above suggests using a friend or a vice to hold the axle. I did the one-man version. Basically I screwed the hub nut back on and stood on it. I then pulled on the axle at the same time as smacking the hub end with a rubber mallet.

(https://i.imgur.com/7j7Xzuy.jpg)

I had already taken the diff end off (wasn't really thinking) and that gave me a little more room to work with.

WARNING! you will end up shoving the axle into your chest. Now this doesn't hurt but (if like me) you have taken the diff end off, you will get covered in grease so you night want to put some tissue on the end.

I also recommend wrapping the hub end with tissue or a rag otherwise when you hit it, grease splats everywhere.

I might start assembly tomorrow though I appear to be short of some boot clamps (lost in the move?).

Spent a bit of time wire brushing and painting the hub side of the drive shafts (pics to follow).

Also turned the car around and started pulling bits off the front. I removed the fog lights, oil and power steering coolers, but I suspect I will end up putting them back on again.

Notice the rust which appears all too commonly in the engine bay.

I appear to be very horny. As well as the standard one I have 2 of these. I can only assume it was fitted with the alarm?

Once I had the original axles apart I spent some (unnecessary) time cleaning them up and giving them a new coat of paint. Now for assembly.

STAGE 2

1 - These are the parts for the hub side of the shaft. The original RX7 hub spline and bearing cage. Also the DSS bearing core.

(https://i.imgur.com/2qvQlL0.jpg)

2 - There are no instructions with these kits so you kind of have to guess/assume how things go together This is the orientation of the parts (I hope). Notice the bearing cage has a slightly larger radiused recess which points away from the spline.

(https://i.imgur.com/MCYEaXx.jpg)

Drop the cage into the housing. You need to keep the gaps on the sides (as pictured) otherwise it won't go in.

(https://i.imgur.com/ia6LIM5.jpg)

(https://i.imgur.com/ZKzkn7s.jpg)
3 - Now put the core into the cage. To do this you need to hook one of the points into one of the holes in the cage.

(https://i.imgur.com/ZKzkn7s.jpg)

Take note of the core orientation. The flat surface (I assumed) was the clip side and the other side is tapered at the opening so the c-clip slides in.

(http://i253.photobucket.com/albums/hh79/gunnytron/Build%20Thread/E3C56AFA-CEB9-42E6-BC85-A2AE7D6B654B-2237-000000BDD88BAC20.jpg)

4 - Next you need to twist the core and cage so that you can start pushing the bearings in from the outside. The first three go in pretty easy.

(https://i.imgur.com/q3qZZtt.jpg)

To get the last few in I had to use a screwdriver to lever the cage up to make room.

(https://i.imgur.com/iVsTy3r.jpg)

(https://i.imgur.com/wTg1Kyp.jpg)

5 - Now you can slide the rubber boot on the shaft and push it into the core. When I did this one went in easily and the other took me several evenings. No matter how hard I tried, the c-clip simply wouldn't pass through. Then, after a forehead slapping moment I realised that the shaft had been supplied with the c-clip and circlip on the wrong ends. One of the grooves these sit in is deeper than the other. I swapped the clips and bingo, it went in nicely.

6 - Slide the boot over the housing, put a clip on and tighten. Job done (partly). I resented buying a proper tool for the clips so I made a botch-job version myself. Worked great :)

STAGE 3

Now for the diff end.

1 - Slide the boot onto the driveshaft

(https://i.imgur.com/Ku7zBpM.jpg)

2 - This is the centre section. Note the orientation of the core. Again ( I assumed) the flush edge is the one the circlip rests on. The face you can see here is the one that faces away from the diff (not the circlip end). I lubed this up ready for assembly. Keep the mating surfaces as clean as you can because you need to put silicone on them.

(https://i.imgur.com/N9p0XQO.jpg)

(https://i.imgur.com/hUmS6cl.jpg)

3 - Put silicone on the outer cap. I also put it on the inner cap. It just made sense to me.

(https://i.imgur.com/TW07Qyr.jpg)

(https://i.imgur.com/gfzALEA.jpg)

(https://i.imgur.com/O4rW9cb.jpg)

4 - Slide the centre section onto the drive shaft then put on the circlip.

(https://i.imgur.com/AuiL3md.jpg)

5 - Now put on the end cap and slide the boot up making sure the holes all line up.

(https://i.imgur.com/lWoBiMp.jpg)

6 - Slide the bolts through the center section assembly and then screw them into the end section. These are supposed to be torqued up to 57 lb/ft but I couldn't manage this as there's not much to grab hold of. I will tighten them correctly once I have them back on the car and I can put the brake on.

(https://i.imgur.com/gCgilUw.jpg)

That's it. There is something very satisfying about these I feel :)

Had quite a good few goes at the car this weekend. I got the suspension, steering rack, rollbar and sub-frame off. I also took out the old pump assembly and drained the tank.

I didn't take any pics of the current state for some reason.

Been busy this weekend. Went back to my mates workshop and got on with a few things.

Firstly I worked on the fuel tank cap making the hole for the an bulkhead fitting.

(https://i.imgur.com/VRRrMlt.jpg)

Not a pretty solution but I had to cut some of the frame away so that I had a decent surface for the ptfe washer.
(https://i.imgur.com/iGlZO6R.jpg)

I also cut the pump holder so that I could sit the 044 in it. Again, bit messy and not very accurate but no-one will see it. Well, unless your reading this :)

(https://i.imgur.com/U7nfp9M.jpg)

(https://i.imgur.com/JqlSChW.jpg)

Cut the steering rack so UJ so that I can flip it.
(https://i.imgur.com/SVzpltv.jpg)

I also got a good few hours in with the bead blaster. Components ready for powder coating.

I really f£&@!?ed these up taking them off. I love my pry bar, has to be one my best buys but in this situation I shouldn't have used it. I didn't realize the nuts were spot welded. The results is some very deformed steering rack clamps.

Finished pump assembly at last. The tank seal had shrunk a bit so I had to soak it in hot water and give it a stretch to fit.

I had originally intended to sit the base of the 044 in the cut-out bottom plate in a similar way to the OEM pump. I dropped that idea when I realised that it would sit a lot lower than the OEM.

I used rubber hose for my pump to hat line as well. I havent had much fuel in it yet, but I keep feeling like it wasnt the right thing to do.

Have you had any experience doing that before? I feel like the fuel will eat away at the rubber fuel line.

No, not done it before but I specifically ordered submersible (in tank) fuel line designed for the purpose. I wouldn't even consider normal fuel hose as it will swell and split from what I read.

Aeromotive in-tank pumps come with a hose setup anyway. There have been a few people complaining of the pipe failing though. I can only assume/hope that they simply were sent a wrong batch of fuel line.

Looks like you fitted new terminals into the tank side of the connctor plug for your pump. Would you mind sharing where you sourced these or confirm the below pieces are correct?

I didn't replace the pins. I spent ages trying to find some new ones but ended up using a small screwdriver to split them apart. I tinned the wire then crushed them closed again. Then did another layer of solder just to be sure.

Actually it's worth noting that I think the wire I used is probably the maximum thickness you can go with. It was all very tight including getting the plastic sleeve into the fitting. Bear this in mind if your going for heavier gauge.

Spent some time at my mates workshop..... Again.

Got all of the bushes out of the suspension. This was alot harder work than I expected. The simple ones I got out using the press but the majority of them I did with a vice and brute force.
Luckily they had a massive array of huge sockets which made things easier.

Hey man!

I just finished modifying my clutch pedal bracket in order to mount a Wilwood MC on the passenger side of the firewall on my RHD swap.  I'm looking at your picture and thinking to myself that you may have some issues with where you intend to mount your MC.  I decided on my placement after many measurements and unless the Monaro unit is a lot smaller than it looks, I think it may be in a spatial conflict with your driver's side cylinder head when you get your engine installed.  I just thought I'd give you a heads up since it was a big surprise for me too.

Best of luck!

Thanks. The mOnaro unit is small. Other guys with RHD builds have used them but not sure if they were using Samberg mounting gear.

Close to a test fit so hopefully I will find out soon.

Just had a measure up on ours, there is 35mm between the bulkhead and the (LS3) head using the Samberg subframe.  I would suggest you need a minimum of 6mm clearance leaving you just 29mm.

Well there's something in the region of 48mm from the end of the mounting stud.

It's pretty common to use this slave over hear so I should be OK with some tweaking. If all else fails I will have to go back to the drawing board and copy Zeeshan's idea.

The GTO MC is used in the UK, but not mounted like yours with a Samberg subframe. I believe it has to be mounted behind the face plate deeper into the car. This thread shows the detail.

Hopefully these pics will help, I have the GTO/Holden clutch master but mine has been modified and works extremely well. I have also made a reinforced rubber gasket on the firewall that fits tightly on the master to block heat and fumes very successful.

-The mounting position you currently have yours sitting in is correct but you need to weld/tack a 10mm thick nut to form a spacer at the end of the clutch pedal firewall bolt posts, this will give you the clearance needed from the head (see pic).
[attach=6]
- The end of the master cylinder has been milled back enough to help with clearance but not enough to affect the clutch line thread and seal.

[attach=4]

[attach=5]

-I used the banjo bolt on the clutch slave and also installed a remote bleeder for ease of bleeding.

[attach=2]

[attach=3]

-modify the piston on the master the standard bore size is only 3/4 (19mm) mine has been bored out and stainless steel sleeved to 7/8 (21mm) and the old plastic piston replaced with a new billet aluminium one, this will give you a short pedal travel with more fluid the standard 3/4 bore needs more pedal travel meaning the pedal will be wound up towards the steering wheel the 7/8 bore will sit in the standard position.

[attach=1]
Title: Re: UK RHD LS1 8.8 FD Gunnytron's build thread
Post by: Gunnytron on October 20, 2012, 09:59:40 AM
Cool, thanks. So was your billet piston custom made? any pics?

Also, how do you know that you are getting the correct travel/flow with the modified cylinder?
Title: Re: UK RHD LS1 8.8 FD Gunnytron's build thread
Post by: moores.4 on October 20, 2012, 09:34:47 PM
Sorry no pics on the piston, and yes it was custom made by a brake shop when he bored it out and sleeved it. Knowing the travel was also worked out by the brake guy as he seen where my pedal was positioned and said that if we took it out to 7/8 that would allow the pedal to come down to OEM position and the correct amount of fluid would operate the slave. I also flattened out the stop point on the clutch pedal base this allows the pedal to go right to the floor. The piston push rod is fully threaded and is separate from the piston so that when you set it up make sure that when the pedal is all the way up it has free play with no pressure on the piston. 
[attach=1]

Don't forget to weld/tack a 10mm spacer (I used a 10mm thick nut with a large internal diameter to match the OEM posts.) at the end of the firewall bolt posts this will position the pedal assembly back there is enough adjustment on the dash mounting hole as this is already factory slotted. You will also need to enlarge the hole in the firewall to push the master through don't oversize it as this is double metal and gives the strength in the firewall (stops flexing) when pushing in the clutch pedal.

Post by: Gunnytron on October 21, 2012, 01:21:10 PM
I will use the 10mm spacers to start off with. I don't think it will be easy to find a company that will be able to create a custom piston.

Had a busy weekend.

Firstly, I re-tapped the thread on my wishbones. Only the top few were damaged so didn't take much. It was a bit fiddly though as there's not much room.

(https://i.imgur.com/lflPdE8.jpg)

I got the engine in too, woot!. It's only a test fit but still feels like good progress.

Waiting to go in

Getting there

In
(https://i.imgur.com/h4eljSn.jpg)

With the bulkhead lip still on I had to get creative with the hoist bracket to get the engine tucked in. It's a bit botch job but it only had to take the strain whilst I gave the engine a nudge. (EDIT: this still wasn't enough. I had to get a shorter bolt as I couldn't get the engine close enough to the bulkhead to fit the mounts correctly.

Spent a lot of time messing about getting the engine to sit correctly. I was going to drill the transmission mount holes but glad I didn't as I was 100% happy with the engine mount alignment.

I took the engine out a couple of times so I could smack the bulkhead to make room for the Fast intake. I think I ended up going a little too far but hopefully there's nothing behind the bulkhead to damage?

I cut the lip with my trusty Dremmel. I ran out of super heavy duty disks so had to use the "heavy duty" ones. I went through a whole tub of the buggers. Didn't half make a mess too.

It was all nice and neat till I got heavy with a lump hammer. Now the remains of the lip is a mess. The three layers of metal are all mangled so I will have to get a grinder to it and get someone over to weld the seam.

Thought I've seen others say they don't need to pound the firewall. I think we all do with the Samberg mounts. My LS6 plenum needed it anyway.

I found the firewall will move so much then the very thin skins start to separate at the seam. I used some adhesive heat shield tape to make the area look tidy.

It's my understanding that the fast intakes are bigger. Might be wrong though. I did a test fit and there was no chance of doing it without getting hulk on it.

Well I don't know why this has taken so long but I finally got the gearbox mount installed. This was a bit of a pig to fit as I struggled to get the bolt holes lined up quite right (despite numerous test fits), then I managed the cross thread one of the nuts a little.

I managed to leave the carpet in buy removing the seats and wedging wood blocks under it so that I didn't drill through it.

I agree, we got most of ours from Earls at Silverstone.  If you have not piped the power steering yet they sell a weld on AN fitting that fits nicely on the end of the original FD flexi hose from the rack, just below the alternator.  They also have the correct PS rated hose.

Going to have to do a little rethink on my AN steam lines.

The upright fixing goes above the input on the expansion tank so plumbing it would be messy. It's more cramped there than I realised so I really need to have a setup where the fixing goes out of the adapter at 90 degrees.

If you get stuck, I can sell you a replacement set. I've got a stock front setup spare and the larger 314x32mm setup from a late spec RS/RZ. Have spare rear rotors also somewhere.

Alternatively I have a 330mm AP BBK for sale too. Its listed on FDUK.

My build has been pretty non-active recently due to a money shortage. I was getting twitchy so thought I would test fit the headers.

Good new is the steering rack clears the header. I don't think the boot will survive long there though so I am going to have to find an alternative heat proof covering.

(https://i.imgur.com/jiYem1n.jpg)

The bad news is that the header has only about 1mm gap next to the frame rail. Not sure what to do about this. Options as I see it are:
1 - Bash the frame rail in
2 - Bash the header in
3 - Create an angled spacer that goes between the engine and the header so that it kicks the header inward a bit

(https://i.imgur.com/W5iDe4P.jpg)

(https://i.imgur.com/GJF5KEb.jpg)

I also want to sort the parts I need for my intake. I have done a test fit of the Hinson rad but I am not sure which hole to mount it in. No matter which one I use there is very little space between the water pump and fan. Not only that but there is also very little space for intake piping.

I may have to look at getting a lower profile fan. Ideally I would like enough lean on the rad so that I can get an OTR working. Failing that I will be going for a 102mm piping setup.

I have pretty much decided that cutting the headers by the flange then bending and re- welding is the best option for the headers.

With the steering joint I will probably wrap some heat shield around it or maybe make a heat shield plate and bolt it to the chassis rail. I would have thought that plenty of people on here have already done something similar but not looked yet.

Post by: 4packet on March 27, 2013, 05:32:08 AM
From memory I think most have melted the boot in the first instance and then given up on it and just removed it. Pete's car in the UK had the Hinson headers. Think he said it took 2 or 3 goes at Hinson sending a part that would remotely fit and he still had issues with heat and the steering joint catching them.

It's what convinced me to stick with the LS3 Camaro maniflds.

Clearance in the joint isn't too bad actually. But you certainly can't say the headers are a good fit.

Still, I got then secondhand and cutting and welding them is going to be cheaper than custom jobs.

Post by: bimbleuk on March 28, 2013, 12:30:22 PM
I used some reflective heat shield and a couple of high temp zip ties and my boot is still intact after 3 years. The collectors on yours probably don't help the fitment but they look like they'll flow well so worth a bit of hassle!

Not much to report still.

I removed the rear caliper for rebuilding and painting and will get the other off tomorrow.

I test fitted the other header and there is loads of room that side. With the problematic one I have decided to let the exhaust shop sort when I get my system made (way off yet).

I left the rubber boot in place. Depends on how much yours will chafe.

I also wrapped the primaries on but left an inch or so gap from the head just in case the flange got too hot and warped.

1 - Current Samberg - Relatively expensive and it can potentially chew bushes.
2 - Samberg rear subframe - If he actually goes ahead with this it will mean a better exhaust route, but more expensive again (god know what shipping to UK would be).
3 - Wait for the guy from Dyno Torque over here to finish his mount. This would be my preferred option, but He is obviously very busy but it's been over a year since he announced it and there's still no eta (if ever).

Good news is I am 99% sure that I am going to settle for the EFI HP LS1 ecu and loom combo. This resolves my problem of not currently having a loom and also, in the long run, should save me some money from visits to tuners. Especially if/when I stick a lumpier cam in it.

The downside is that it's not cheap at £1300 to my door (tax and import duty included). Most place appear to sell it for about $1400 so if anyone knows of it being cheaper let me know (I want to be able to get tech support so no random eBay people).

One thing to note is that apparently there is a newer version that no longer has the issue with the GM coils. I did have the part number somewhere.

Thought I would try to do a very rough mockup of an OTR.

There isn't too much room over the Hinson rad. It is currently mounted in what I believe to be the standard position, but even then the alloy plate doesn't line up with the bolt holes as the fan hits the water pump. I am going to have to look into some alternative fans I think.

Here's the masterpiece

Side view showing the clearance

This is just an idea I am kicking around at the mo. I will draw it up in a 3D package and then think about getting made up in ali or maybe even moulded in fibreglass. The long brown box under the radiator tabs is a mockup of a K&N panel filter. Currently it is pointing towards the rad, which isn't ideal. I may tilt it the other way a bit so it's not sucking air through the rad.

My build has been pretty non-active recently due to a money shortage. I was getting twitchy so thought I would test fit the headers.

Good new is the steering rack clears the header. I don't think the boot will survive long there though so I am going to have to find an alternative heat proof covering.

The bad news is that the header has only about 1mm gap next to the frame rail. Not sure what to do about this. Options as I see it are:
1 - Bash the frame rail in
2 - Bash the header in
3 - Create an angled spacer that goes between the engine and the header so that it kicks the header inward a bit

Painted the IAC as it was looking a bit tatty.

I spent a bit more time trying my rad in different bolt holes. This pic is of it in the last chassis rail hole (4th). Plenty of room like this but I didn't like the way it stuck out the front. I then tried it in the second hole from front (3rd) and this appears to be the intended location. There's still room between the fan and pump and it also allows me to have a go at making an OTR.

I bought a cheap filter so that I could create a reasonably accurate template for a custom OTR.

Finished the mockup reasonably late so will have a test fit tomorrow.

Obviously the front wont be open as in the pic.

The intake fits fine for the bonnet but the bulkhead had to have a hefty smack.

The TB front edge has had the corner ground off by the previous owner. He was running Hinson subframe though (I am on Samberg) so it probably doesn't mess to be.

Still making the intake. The good news is I think I have a final mockup so hopefully I will get it made soon.

I Purchased a Mazda 323 wheel and fitted that (not done electrics yet). It's amazing how much lighter it is than the old one.

Almost seams silly not to pin the crank whilst it's off.

You driven the car since the heads and can swap? What spec you go for?

My pulley is on now so I'm going to mark the bolt and pulley for location and check it.

I was waiting for 243 heads to come up and some did on the HSV/Monaro forum. Bought them and spent the next 2-3 weeks porting them at home. I'd already bought a low mileage Comp Cams kit from Craig including a 222/224 566/568 112 cam, dual springs, push rods. Also had the ATI pulley and LS7 lifters tucked away waiting for the right day.

So far I've only driven it a few times but the impression is that the engine revs better without the heavy cast crank pulley and feels smoother to me anyway. As for power well I've gained another 1000 RPM as it's still making power right up to 7K! my exhaust is restricting any actual gains in peak numbers until I change it (I can compare airflow numbers in the EFI Live software).

I have to confess that I have yet to find the patience to read up on cam and head numbers. It's all a little gibberish to me at the mo.

I don't really know even what I have got on mine. I may actually be better off selling mine and buying a complete kit.

Maybe it would be cheaper just to supercharge or turbo it :)

Just depends on your aim. Mine was to increase the useable rev range as I was not getting the best use of the gearing. The mild cam has done that. For more power then yeah forced induction.

I 've been checking some of my logs and to back up that feeling of the engine being smoother. So far I've not seen any knock spikes in the maps where before I used to get the odd 0.5 - 1 deg peak during a WOT power run. I think they were mechanical knocks not true detonation so it does appear to be smoother. I can only assume the ATI crank is helping.

The engine bay is pretty much stripped now. I can't figure out how to disconnect the engine bay loom from inside the car though. I can't see where it goes. I may have to dismantle the dash.

I enlarged the hole for the clutch master cylinder. With the spacers on it protrudes a little under 35mm. Hopefully that will be enough clearance.

I didn't bother taking pictures, but I finally got my dash out. There were only a few cables holding it in actually, so was very easy.

Now I can get the bulkhead welded and have access to seal it from inside the car. Once that's done I can get someone to paint the bay and spend some time tarting up the engine.

So good.




Wish I'd spent a bit more time putting mine together to do things like the gauge cluster and clean up some more things in the car befpre throwing it back together... I'll probably do that whenever I have to swap to another FD chassis after totaling this one hahah

Should look good with the coils relocated?

I'm about to relocate mine but for a different reason because I'm planning to have an airbox sat on each side due to my most recent silly purchase. The filler will have to go too most likely.

I may need longer leads too depending on where the coils end up.

Just checked that 86 out, looks and sounds awesome. Never looked at ITBs before. You get much of a power gain? you intending to cut your bonnet or squeeze it under?
Title: Re: UK RHD LS1 8.8 FD Gunnytron's build thread
Post by: bimbleuk on January 27, 2014, 08:50:20 PM
Simple answer is yes you get gains all over from using the ITBs. Though they are best used on cams that usually cause chop and stalling/surging with a plenum. The problem is you often can't get a decent MAP signal and you've ditched the MAF already so you end up mapping mostly on TPS/RPM. Very basic mapping but susceptible to atmos. changes without careful mapping and a decent computer. Luckily the LS1B PCM with EFI Live enables a TPS VE table that works with the usual IAT/ETC/BARO compensation tables.

My current cam is pretty tame really so it's more of an install and tuning exercise for me. I think I can just squeeze them under the bonnet but I will need to make some curved air horns over the valve covers. Backup plan is just to cut my spare bonnet and go with foam filters similar to the Driftworks car. Air boxes under the bonnet would be quieter for track days.

Post by: bimbleuk on January 28, 2014, 06:34:27 AM
Yeah it's taken me few months and a bit of trial and error to get savvy with all the terms and turn it into practise.

So usually the PCM uses the MAP/MAF sensors in combination to calculate the air entering the engine. Without those you can use throttle position against RPM which is great on track as you get the best throttle response. Not so good driving in traffic in the rain on a cold day. That's where the correction tables such as inlet temp (IAT), Coolant temp (ECT) and atmospheric pressure (BARO) come in handy.

Got my bulkhead seam welded up today so next step is to get it to the paintshop.
(https://i.imgur.com/8BAhhKG.jpg)

I've also been spending lots of time tweaking the gauge install. My initial holes were too far off so i've had to pack out the rear with some plastic sheet. The bonus is that it's a nice flat surface for the screw clamps. It's still not perfect so needs a little tweeking.

Got busy with the wrinkle paint today. I am pretty pleased with the valve covers. They aren't perfect though as I didn't lay the paint down thick enough on the sides by the edge lips. As it's not likely to be very visible I am not that bothered.

There is a blemish on the top near the oil filler hole. This was caused by an air pocket which I assume was in the filler. Again, not too obvious so I am not going to do anything to it.

(https://i.imgur.com/futCm25.jpg)

(https://i.imgur.com/zNdQMm3.jpg)

I have thought about trying to cover them with a matt paint as I don't 100% like the way they look white when they catch the light. But that's just being fussy.

Unfortunately the intake didn't come out so well. I didn't lay paint down thick enough on the first layer so I have flat spot. Going to have to take this back down again and repaint.

As above the valve covers look, pity they'll be mostly covered unlike the intake!

I had to cut a hole in the middle of my firewall, make a dent for the throttle position sensor and relocated the front brake line T at the weekend. There was me thinking I'd only have problems closing the bonnet on the new ITBs!

Make the brackets! I've seen the ones on Ebay.com and they're just a bent bit of ally with some spacers. Can't be beyond your fabbing skills.

I've decided to mount mine behind each front wing and just ordered two 36" loom extensions from Ebay.com as the exchange rate is favourable. As usual my sis is getting the job of shipping them over to me.

I stuck the parts and the cans on the house radiators to heat them up. I then had a small heater running in the spray tent. I did it on a cold day though so the Ali didn't stay warm that long. The covers just fitted in the oven. The intake was heated with a heat gun.

I thought about how many times I've touched the coils in the 3 years the cars been running and I could only think of when I swapped the 243 heads in.

I think it's an advantage as they get pretty hot in summer sat on the rocker covers and at worst I was getting a slight misfire at idle. Mostly cured though when I switched to a Mazdaspeed style bonnet.

Ever feel like your going backwards rather than forwards?

Degreased, wirebrushed then scotchpaded every inch of the box and block with degreaser. Will wash it off tomorrow and hopefully have to to give it a coat of paint.

Also tapped a couple of holes that had been stripped. One was on the engine mount and one was a manifold bolt hole.

Had a relatively busy week with the car.

Last week I sprayed all the cavities in the bay with Dinitrol rust converter and also filled and painted the holes I made when removing the tunnel brace mount.

I painted the ABS bracket and base along with the bolts. Some of it has gone matt though as it was damp outside. Hopefully a polish will bring it up again.

(https://i.imgur.com/0X2f6r1.jpg)

This weekend I sprayed Dynax S50 in to the cavities, then spent a good 4+ hours going over any seams that were missed by the garage (used epoxy mastic). There's a lot of nooks and crannies which makes it a really tedious job, not to mention messy.

Here's a view in to one of the frame rails:
(https://i.imgur.com/OxMadSz.jpg)

I still need to figure a way of getting the crap out of the cam sensor hole. I may have to blow it down and take the sump off to clean it out. Not sure how much room there is though.

(https://i.imgur.com/rtuiZPF.jpg)

I got a new rear o-ring for the water pump so that can be prepped for paint now.

Firstly took off the sump. Turns out the sump gasket is shot.

But, after an hour or so I got it all clean. I looked up under the engine and got in there with an earbud taped to a skewer to reach up inside. I then turned the engine 1/8 turn then repeated the process.

After a bit of a faf I got the rear subframe out. It's in a bit of a state and I can't be bothered to spend ages tidying it up so I purchased one that has already been dipped. Hopefully this coming week I will be getting the front diff mount welded in.

I still could do with the height that the standard bushes sit above the subframe mounts. I know that the pinion angle needs to be 2.5 degrees (relative to flat of subframe top), but I want to make sure I have plenty of room to play with.

(https://i.imgur.com/LBTuBep.jpg)

Also tarted up the ABS pump a bit. I could have done it alot better but fully dismantling it would have been loads of work. Besides, I am not going for a show car finish.

Got started on the cobra diff mount. This is going to be a lot of trial and error as the car is miles away from where the workshop is.

So far the cross bar has been bent and spot welded so that I can move it about a little. It is sitting quite proud of the subframe at the moment so I suspect it may hit the underside of the car.

(https://i.imgur.com/WHcRdBJ.jpg)

(https://i.imgur.com/1ABuV4W.jpg)

(https://i.imgur.com/TqbWHfA.jpg)

I also started making a blanking plate for the clutch master, blasted and painted the brake servo heat shields (not sure if I will be using them), drilled the blanking plate ready for the tapping a 1/8 NPT for the speedhut oil sensor. Blasted the rear anti-roll bar and the fuel tank straps but these need soaking in anti rust as they got surface rust almost instantly.

I also had to file the middle holes on the Samberg batwings. I don't know if I am just unlucky, but that's twice I have had to modify bolt hole locations on Justin's stuff.

The brake lines that run round the rear subframe also need to be remade as they are a bit too corroded. I blasted the line splitter for them though.

Bit of a fail on the pipe for the subframe. There's no way it will fit in its current shape as it hits the seat wells.

I'd add a bars on the top that go back up top similar to ronins. Well it wouldn't be similar it would be practically the same thing. Closer to where the subframe is bolted solid to the car so the area of the subframe that spans between the mounting points isn't taking all the load.

Well spotted :)

How's your tune going?


I've had it running for a few weeks and mapped the part throttle stuff fairly easily on the road after spending quite a while balancing all the throttle linkages etc. I initially tried to stay Speed Density (retaining the MAP sensor) assuming that Alpha-N (throttle and RPM only) would make it a pig to setup. I was wrong as it's been fine and now actually idles and drives better with the mildly lumpy cam than ever before! I can now see why you can run very extreme cams with ITBs and not have the stutters and surges of a single plenum.

The ECU still references MAP for live corrections so it's not some highly strung race car. Cold starts require a tiny push on the throttle for say 30 secs as theirs no idle control valve but after that it's solid. I've not changed the factory settings so maybe it just needs more time playing.

I spent a couple of hours on a dyno Friday populating the high RPM cells but we were struggling with wheel speed and grip on the aging dyno but it's at least safe to boot it and hold it under power. So I'll be out early tomorrow doing some doing 3rd & 4th gear runs to correct the areas we've deliberately over fuelled. Not saying it's perfect as I'm still learning about the fuel dynamics and injector timing tables but it's 90% there now at least.

Spent alot of time in the garage this weekend. THere was no news on my rear subframe mount so I bit the bullet and put the rear subframe and suspension all back on so I could pull the car out and work on the engine.

I swapped my cam out and fitted all new seals and timing chain. Cleaned the sump out and fitted the boss for the ATI balancer.

I didn't get the chance to use the pushrod checker.

Rear subframe all ready for welding. The new shape leaves plenty of clearance and I shouldn't have to relocate anything except maybe the charcoal canister.

I shot blasted and repaint my rear ARB (couldn't get a decent pick).

I am now in the throws of removing the rust from the seams of the fuel tank. Very boring job. Also giving the brake cylinder a spruce up.

Good to see the progress.

Can you make another :) I have a spare frame and after that recent event I think my original diff is starting to show some stress! I have a spare diff with new bearings but I think I may be pushing the limits on the Mazda diffs.

I did use the rod checker at the weekend and that indicates one size down from the current 7.4 to 7.375 would be ideal. Not sure if that's worth changing but as I'm probably going to order some gaskets, chain and a trunion upgrade I may as well get a set of rods.

I'd hate to think how many hours I put into that. I way underestimated how long what with mockup after mockup, tedious nibbling away at the metal work with the grinder until it fitted. So no, I can't make you one :)

I took it to the powder coaters yesterday so soon it will be finished.

I am ignoring my valve train at the mo. when I get closer to startup point I will look at it again. Currently I am still not 100% understand the whole valve setup scenario.

Fair enough there's plenty of jobs I've undertaken on mine that I'd rather not try to do again from scratch. Pedal box install & air boxes for example. I'll probably update my thread later as I've gone in slightly different direction with the filtering now.

I've gone with just a trunion upgrade in the end. I've also ordered a set of 7.375 rods (plus a chain and a few gaskets). The 7.4 rods would have been fine but I've had the heads lightly skimmed and I lapped the valve seats so that appears to have been enough to warranty one size down. I'll do a rocker wipe test when they arrive.

Brake lines should be easy after that. I did the trunnion upgrade this morning, which probably took an hour if that. Floor standing press makes it a doddle.

Trunion upgrade in an hour sounds darn quick. Maybe one if the few jobs that takes less time than expected. Not for me though as I have brass collars. Probably going to go for comp ultra golds.

I have already bent the brake line pipes, did it in my lunch brake. Just need to get hold of a flaring tool to finish them off.

In the mean time I have been painting even more bolts.

Check the length of the tubes in those batwing mounts, they need to be long enough to stop you crimping the subframe lugs together.  The ones Justin supplied us with were about 1/4" too short.

The tube is about 2-3mm shorter each end. It was my belief that they weren't supposed to be flush with the ends of the bushes so that there is some pre-load.

Excellent work so far! I'm having my subframe powder coated as well and my local Mazda dealer can't find any subframe bushings in stock (the bushings that press into the top of the subframe where the locating pins/bolts are).  Did you find new replacments or did you re-use your old ones?

You're 8.8 setup looks great.

For what it's worth, i've had issues with my axle boots hitting the brake lines. (it seems to happen with the power turned up and at higher speeds)
A couple others chimed in on my thread when I mentioned it, so i'm not the only guy who's experienced this. I've been through 5 boots in less than a year!

The first time it happened, it literally bent the driver's side brake line and the line BROKE OFF when i tried to push it back into it's correct location. I then moved the lines higher up in the subframe with adapters and SS braided lines. It was fine for a little while, but the boots hit again, just not as bad. I've now completely moved them out of that area and to the rear of the subframe to ensure it never happens again.

So now i'm pissed off. I went to bleed my clutch slave today but found that the bleed line I bought wouldn't seal. Initially I thought it was because the bleed nipple wasn't long enough so I ground the end of the line off, but even after doing that the nipple wouldn't seal.

I can only assume that the line hasn't been made correctly or the bleed nipple is tapered at the wrong angle (do they even do different tapers?).

I had hoped to get the engine back in this weekend. GRRRRR!!!

I'll also chime in about the axle boot and brake line problem. Last year my brother had his FD on the dyno, on the way home the brakes stopped working. I think the strap from the dyno may have rubbed the boot, causing it to rip, and then flying off and smacking the brake line. Wasn't fun driving on the highway without brakes. Maybe a shield or relocation will eliminate any problems.

After my setback I did manage to do a few small jobs.

I put some nutserts into the chassis and mounted the clutch reservoir and also made a heat shield/master cylinder bracket.

I also fitted lots of random stuff back in the bay such as clips, rubber strips and such like. Feels sooo good to be putting parts back on for a change.

No pics though as I have sold my fancy pants camera and my phone is pants in low light.

Well, it's been a frustration month. I feel that forces are determined to stop me getting my engine back in...perhaps I am being a little melodramatic :)

After waiting a couple of weeks to get my new clutch bleed fitting I finally managed to bleed the clutch and looked forward to getting the engine in. I then noticed that the paint shop had cut corners and not properly treated the welded seam under the bulkhead.

So, I decided to paint it with some of the leftover paint the body shop gave me. I primed and masked everything off and borrowed an airbrush. Foolishly I thought the airbrush would work, but alas no. So, that's another wasted weekend grrrrr.

I did get a few parts painted up

I finally finished the new brake line I made. It took a bit of fiddling as I had to raise the brake line splitter so it cleared the subframe. At the same time it had to loop around the fuel hardline.

I also made up the braided fuel hoses for the rear. I still need to decide how I am going to secure them, but I have some p-clips that should be enough. Once I have done that I just have to sort the fuel tank breather lines, then I can get the diff in and the axles on.

Another 2 days at my mates workshop. Bit of deja vu here as I bead blasted the other set of suspension arms. These will be clear coated and will retain the Mazda bushes as I won't have the money for a full poly bush set for the arms I have already done.

This time I also broke the hubs apart. The fronts had a quick coat of VHT as they are steel.

(https://i.imgur.com/LjKPbOb.jpg)

I also took the rear bearings off. Removing the inner race from the hub shaft was done in seconds with the right tool. Only problem was that the wheel bearings I ordered didn't fit. Looks like I have ti import some.

(https://i.imgur.com/RGJdeKn.jpg)

I also got the right hand header flange straightened out. I then bolted the flange down to a huge lump of steel to keep it flat for tack welding. Hopefully the bloody thing will fit this time.

Lastly, this sexy little knurled adapter (simple things) was made so I can fit the triaxe handle.

No pics, but the last bushes for the diff have now been finished so that can get finally bolted in.

I now have my second set of suspension back from the painters, but I am waiting for my bearings to turn up before I can fit it.

I have finished painting, sealing and sound proofing the bulkhead.

(https://i.imgur.com/kdUVLgn.jpg)

I have also mounted the rad and the intake (temporarily) and it looks like I am going to have to cut a section out of one of the bonnet supports as I can't quite close it.

For the diff breather pipe I have decided to route the hose to the left rear wheel arch and then mount the rubber bulge next to the fuel filler pipe.

A few small victories today.

Washed and put mastic on any rust patches in the wheel arches (not many). Next is to spray rust converter where I couldn't reach and then coat the arches in anti-stone chip.

(https://i.imgur.com/w4xhqS8.jpg)

Tightened the clutch pedal. Not much clearance between the master and head.

(https://i.imgur.com/e1OaUbb.jpg)

There is one bolt in the water pump that is stopping me from fitting my power steering line. It's in the perfect place to make it impossible to tighten the fittings. I am going to fit a flush bolt.

Getting "back" on the road...it's never been running :)

I am hoping to get a start up by the summer. I keep thinking that I don't have much left to do then spend all weekend in the garage and come out without ticking anything off my check list.

The biggest hurdle now will be the bay wiring. I've been avoiding it, but I will have to get on with it before too long.

I also need to figure out how I am going to hold the top of the rad.

After lots of pondering I have decided to sell the YT rockers and springs etc, and get Comp Arc Utra-Golds with BTR springs. I have already ordered some YT rubber gasket/spacers. New rocker will come nearer startup time.

At least you guys can do a decent job now rather the hack job I did to get it running and then suffer some charging issues because I didn't replace the 20 year old battery, alt & starter cables for example.

Yeah, silver linings and all that.

My wiring will be a 2 stage job.

Stage 1: make sure everything I need still works

Stage 2: relocate fuse boxes, battery and relays

I was surprised how hard it is to find water tight relay holders over hear. No fancy Bussmann stuff for me :(.

I had a clearance issue when I removed the Power steering pump as the belt wrap meant it was fouling on one of the alternator bolts. Quick fix was to chop a section off the bolt head which of course makes it tricky to get out again! That needs a longer bolt and a bit of sleeving.

I've had a nagging issue when tuning that the O2s start to wander around idle for no apparent reason plus some instability when trying to tune steady state. After much head scratching and diagnosing, yesterday with a mechanics stethoscope. I've decided there's at least one lifter/rod/rocker combo that's just too loud with a distinct tick where the others are more of a mechanical swish. So I've order a new set of lifters, gaskets, bolts etc. to pull the heads again!

At least it was a good excuse to order a 2 part timing cover and fit the other timing, oiling upgrades I've got sitting around. Pity it passed the MOT (that's a UK road worthiness test for others reading) yesterday too.

That sucks. Hopefully there's not any excessive wear on anything.

I think the problem with the bolt happens to the guy I bought the engine from. It didn't come with PS and one of the alternated bolts is missing. Must put that on my purchase list actually.

Attempted to adjust the clutch pedal but found that I don't have enough thread left to make adjustments. I am going to have to cut off the nut from the back of this fitting and weld it inside. Hopefully then I will have a little more adjustment. Of course, I still may not have enough adjustment. I have no idea where the bitting point is at the mo.

Shiny!

If you hadn't seen it there's a Holley split timing cover on the HSV/Monaro parts section on Piston heads. I'd have bought it but I'd already ordered a generic one with my other parts. I've delayed my rebuild by a week or so too as I ordered a small valve spring tester plus an ARP crank bolt (as they're reusable). It's all these annoying little things that are never available over here that is frustrating!

I check pistonheads nearly every day. I did see the cover but didn't really think it was worth while now that I have my pulley on.

Did see some btr springs but they are a few years old and I think they may have changed the design since.

Yes if your pulley is already on then it's not so appealing but for me it was a smallish investment to save time/hassle if I decide to upgrade the cam again later. Hopefully I won't be changing the lifters again at least.

Yeah those BTR springs were tempting but I've got Comp duals already and assuming they're still within tolerance, hence the spring tester, I may as well stick with them.

Post by: Gunnytron on April 10, 2015, 10:33:09 AM
So got all the front harness plugged back in and the result was mixed:

- Turn signals not working (hazards do) - FIXED by plugging in B/W wire that I thought wasn't needed

- Lights work (need to confirm full beam) - full beam works

- Light motors go up, but don't go back down - FIXED, was just the switch on the dash

- Dash warning lights not working - FIXED by plugging in same B/W wire above

- Heater blower works

- Wipers / washer work

I have yet to check the tail lights as they aren't currently fitted. - These work

Air bag system isn't currently working as I haven't wired in the airbag itself. I need to look in to how to test this also.

ABS...again, need to find a way to test this or wait until the cars running and stamp on the brakes.


Things I forgot to check:

- Interior light - works

- Windows and sunroof dont work. I suspect this is due to the aftermarket alarm - FIXED see B/W wire above

- Mirrors - work to a point. I think the drivers side switch only goes up

- Brake lights (need pedal switch) - FIXED

At least all your engine is in the chassis!

I'm putting a new set of lifters in to hopefully get it all a bit smoother at idle. So while it's apart I've got the heads downstairs to check the valve springs with a checker tool I imported. Then I'll measure the push rod lengths etc. again as I put it back together. One thing I spotted so far was one of the inlet rocker bolts was weeping oil on the back of an inlet valve. The bolt holes becomes exposed as a result of the metal removed during porting and clearly I didn't seal that one very well. As it was on the side which had some erratic AFR readings that may have been a contributing factor.

I do feel like I'm getting close. Still need valve springs, pushrods, exhaust, some sort of heater plumbing, brake pads and rear disks, tyres blah blah blah. Still plenty of money to spend :)

Post by: bimbleuk on April 28, 2015, 09:09:36 AM
Plenty of cheap PCV catch cans on Ebay you just have to make your own baffling inside to separate out the oil vapour oh and discard the cheap PVC plastic hoses and use some proper silicone. I often just use stainless wire wool which I use to pack the silencers for baffling as I usually have some in the garage.

Can't help with the exhaust system as a proper setup is always going to be expensive. As for the brake pads as I can only highly recommend the CL RC5+ pads after my initial test but they're twice as much as a set of the more common DS2500. You're welcome to my half used Red Stuff pads though as they won't be going back on!

Making your own baffle is something I hadn't ever considered before. Looks like you may have saved me a few quid there :)

Exhaust hopefully won't be too bad. I headers and y-pipe, then a small silencer that is design to mate to a 3" stock rx7 back box. The only thing is that was based on a Hinson subframe so not 100% sure it will fit.

Thanks for the offer of the pads. Am I to assume that the red stuff aren't that good? I am currently intending to get the 2500s.

They were an OK fast road pad and probably perform fine with assisted brakes. With my unassisted bias setup I needed a fair old prod to get them to bite before they got any heat in them then they would start to work better. The DS2500 appear popular for road and track and are reasonably priced at ~£80 for a front set.

The RC5+ I just fitted are sintered metal, need no bedding in process needed, work the same from cold to hot. I can verify they didn't wilt from several 100+ high speed stops. They haven't squealed at all yet though that was warned might happen but I need to see how the disc wears as I know the RC6 pads will eat them quickly.

I thought it was time for a little update.

Not much to see but I have been spending a lot if time organising my front loom. Yet again I am surprised at how long it takes. I have had the loom in and out of the car several times now, making sure everything I in the right place.

I have moved some wires so they go behind the dash instead if around the bay. This includes wiper motor, and wiring and some other random wires.

I also purchased a second relay box. These are almost modular so I can change my configuration about. I now have space for 6 mini relays, 2 micro and a few slots for mini fuses. This means I should be able to consolidate all the relays to one unit. The exceptions being the fuel pump relay (will go in boot) and the terra relay (which is already tucked under the dash.


(https://i.imgur.com/GxCiB8b.jpg)

This is where the box will sit... But on the other side.
(https://i.imgur.com/K9ubOSQ.jpg)

I still have to wire the relay box in and route the cable from the boot. Then I have to figure out the alternator wiring.

It's all in but I haven't run fuel through it yet.

I ended up having to change some of the connectors at the FPR to get the pipe angles I wanted. The only problem I have now is that the fuel pipe comes up by the bulkhead right where the heater pipes are so I need to bend the hardline.

Fitted the bay harness again today after transferring everything over to the Jeep fuse/relay box.

Few issues:

1 - horn is on as soon as you attach the battery
2 - wiper motor doesn't work
3 - Sunroof doesn't work
4 - Electric mirrors don't work
5 - Heater blower doesn't work
6 - Windscreen washer motor doesn't work

I've not had a chance to see if there is something in common with these circuits yet so hopefully nothing to major.

I am sure the horns is a separate issue. I'm not sure what has changed since before, but I couldn't get them to work at all then so I guess that's progress :)

Here's my relay/fuse box layout

Progress to a point:

1 - horn is on as soon as you attach the battery - spent a while looking at this but I can't see why it isn't working. They are aftermarket horns so maybe I have to wire them differently?
2 - wiper motor doesn't work - this is getting on my nerves. I have power at the fuse, and motor socket but still no go.I can't believe the motor has failed since I last fitted the loom
3 - Sunroof doesn't work - sorted. I missed a couple of plugs
4 - Electric mirrors don't work - sorted. I missed a couple of plugs
5 - Heater blower doesn't work - Now this works to a point. It comes on but pulses on - off - on off, a bit like and indicator. No idea what's happening there.
6 - Windscreen washer motor doesn't work - sorted. I missed a couple of plugs

The only things I've changed since everything last worked was to remove the circuit relay as only one wire was attached to it (apart from the wire that goes to the EGI relay).

3 - Heater blower doesn't work - Now this works to a point. It comes on but pulses on - off - on off, still not sure on this one

No doubt. I want to try plugging the sensor that is on the AC matrix in as that is the only thing I can think of that has changed. Failing that I may have to ask said expert for help :)

The blower's electrical system in the FD is pretty dead simple. You can read the diagram on Z68 of your FSM bible. It consists of a relay, fuse, resistor, position switch, and the actual blower motor. The relay turns on with switched power from the ignition switch. I wouldn't point my finger at the ignition switch otherwise, a lot of other things would be pulsing in the car. The relay could have a bad ground, but your pulses would be accompanied by an audible relay click. Easy to check. Ground for the blower resistor is right below the passenger A pillar. The fuse shouldn't be an issue. The resistor could be an issue as it's the #1 thing to fail in the system, just from my observations of people PMing me and working problems down to the resistor, however, I've never heard of a case that would pulse the motor as the resistor is just a chunk of metal and ceramic and can't change its resistance on the fly unless it's got some kind of crazy thermal runaway thing going on. I suppose the motor could possibly be broken enough to pulse. I'm not sure how the FD's blower motor is constructed, nor am I a motor expert, but I would imagine it's just a simple DC brush motor. I haven't heard of brushes needing to be replaced on the blower motor, but perhaps that could cause the issue? The position switch is simple/mechanical. I don't see how that could pulse the motor. Finally you have the blower motors ground, which could be improperly grounded. It's in the passenger kick panel.

Hope that helps

Thanks for the input Lane. I found out what the problem is and I am a little ashamed.
I noticed that when I touched certain electrical connectors the fan worked fine but it was eratic. After a while I noticed that the dash support was earthing on the gear stick. When I leant over the dash to touch the connectors I broke the earth contact  :banghead:

So all sorted now and I can finally finish wrapping the loom.  8)

Front loom is pretty much in and finished except for the horn. I left a few cables in for fan control which I will sort later.

Started sound proofing the footwells. I decided to cover more critical areas rather than every square inch. It's a balance between weight/cost and dampening.

Compared to your percentage power/torque increase the weight of a couple of packs of that stuff is negligible.

I mostly lined the passenger seat wells where the diff now mounts directly to the car and some over the rear boot area for some exhaust NVH reduction.

Pics to follow but I have finished the bay loom and installed it all. Luckily I spotted that I broke a wire when pushing the plugs through the bulkhead. I think I must have got a bit carried away with the terminal pliers and nearly cut through the wire.

Drilled a hole next to the front loom grommet for the starter motor wire.

Refitted the heater blower etc.

Soundproofed below the rear seats but ran out of stuff before I could get on to the boot.

Made a blanking plate for the AC grommet and cut a new piece of rubber for the oil cooler shroud.

Fuel pump relay wiring is all done also.

Annoyingly I appear to have a leak between the rear housing and the body of the gear box. Luckily I haven't filled the box yet but still a PITA.

Those panels are a real PITA.  Had to take them off to put new seat belts in to meet importation rules here in NZ.

Pretty sure it's belt anchors out, , few external clips and then gently pry with crossed fingers. Has been a while since I did it.

I have spent most of the weekend test fitting and modifying the Holley loom. I have moved the coil pack connector to accommodate the coil relocation. The other side will have to have an extension loom on or I will just cut and extend the wires.

(https://i.imgur.com/yz1MeBz.jpg)

I also moved the fuel pressure sensor plug closer to the bulkhead rather than near the front of the engine and fed a new wire through the loom for the alternator lamp.

Made and fitted the last of the fuel line fittings. It was quite a fiddle doing these up. Hopefully they are tight enough.

(https://i.imgur.com/ItjmwLT.jpg)

I got the an fittings for the remote oil pressure line, but discovered that the 90 degree fitting I got can't be screwed in without taking the intake manifold off.

Here is the fuse box. I still need to make a bracket for it but I need to wait for the rad to come back as it is very tight.

(https://i.imgur.com/mkQIGBa.jpg)

Update on the gear box leak too. Turns out that the drain plug wasn't tight so hopefully that's all sorted now.

I am not happy with the remote map sensor solution I came up with as it isn't secure enough where it join the manifold. I may try to drill a hole and put a nutsert in so that I can clamp it down. Bit scared I will crack the intake though.

I also still need to decide on where to locate the IAT sensor. It may have to go in the EGR hole or alternatively in the silicone coupler (if there's enough room).

Finally got the driver's side header on. This has been a thorn in my side for ages now. I had to get a blowtorch and hammer on it to clear the engine mount. By using a regular hex bolt, no washer and grinding the mount, I managed to get the clearance I need with very little bashing. Unfortunately the previous owner... or Hinsons, have put two larger dents in the same tube so at some point I will have to take the header of again to sort them out.

(https://i.imgur.com/zoR3sNm.jpg)

Got the starter motor fitted and some wires made up. I still need to sort the ignition wire. I covered the existing heat shield with some Dei heat shield as it's darn close to the header.

Unfortunately I also found that there is a leak at the tail shaft seal. I need to check the torque of the bolts, but failing that I am going to have to take the tail shaft off and re-seal it. Yet to figure out if I will be able to do that in situ. I bloody hope so.

Had one of those weekends when everything just goes wrong. You know, you undo a nut and it falls and gets jammed in the headers. You put a socket down and it rolls just out of reach et., etc.  :)

So it looks like the top mounts on my suspension have been mounted the wrong way round or on the wrong strut. The brake cable bracket is facing the rear of the car instead of the front. Not a big deal but really annoying.

I've got my pads now so I fitted one of the front calipers.

I've got a cold now so just spent the day indoors and worked on my catch can baffle:

You can also just about see an issue I have with the pipe from the charcoal canister rubbing on the driveshaft hub. Not quite sure how I am going to sort this yet. Probably cut off the nipple and glue on a curved piece of plastic, just to stop gunk blocking the hole.

(https://i.imgur.com/z9aZ5EF.jpg)

So I am hoping tomorrow I will be able to bleed the brake system. I can then hire a torque wrench big enough to finally tighten the crankshaft pulley bolt. When that's done I can finalise the radiator install.

Great progress! I just read through all 25+ pages! I'm attempting a very similar swap soon (still gathering parts) so I will be watching this closely! My biggest concern right now looks like the clutch master cylinder and drivers side header. I knew it would be a tight squeeze being RHD, but having a custom bored/sleeved master sounds rough! I will be running Sikky mounts, and will be test fitting the engine in the next few days. Thank you for putting so much time and effort in this great write-up!

The LS2 I purchased came with a set of really nice long tubes. Sikky makes headers for their kit, but have confirmed they don't fit a RHD car without modifying (contacts RHD steering shaft). My plan is to see how far off the headers I have are, and possibly modify these, rather than spend money on new headers and still hack them up. I will be starting a build thread here in the coming week(s). I plan on checking back here frequently as well!

Not much worth showing in terms of pictures. I've wired the fan and also realised that I need a relay for my reverse lockout. For that reason I have been slacking as I can't be bothered to unwrap the loom again.

I appear to be spending a lot of time doing jobs that aren't on my job list...again.

I have been sorting small jobs that don't warrant any photographs, lots of which are wiring related such as finalising the starter wiring, making cable that runs to the alternator, feeding gauge wires through the bulkhead blah, blah, blah.

I finally got some tires as my last ones were perished and pushing my car out of the garage with flat tyres wasn't fun.

Finished my speedhut install. The cluster surround needs to be painted, but that can wait.

Thanks. Yep, getting very close.

Need to get an exhaust made up, remake PCV system, mount battery, fit rad (polish/paint shroud), sort heater pipes, few wiring things (rev light, horn, rear fog), make fusebox mount, wire Racelogic TC.

Continuing with all the jobs i've been putting off.

I dropped the sump and resealed in as I had a little leak.

Fixed my main loom, oil pressure sensor and map sensor to the bulkhead.

(https://i.imgur.com/QsEbAcc.jpg)

Drilled out and re-tapped the bolts holes for the front wing as both bolts had sheared off.

I do have a new problem though. Where I located my AIT sensor the huge clip hits the bonnet. Not sure what I am going to do about this yet. Options are to sink it deeper into the intake or finding an alternative lower profile sensor.

Sorted the rear fog light out. I rewired it so that it activates from what was the front fog switch on the center console. I didn't bother taking pics, but it was relatively involved. The previous owner had rewired the DS reverse light, which was fine, but the wire wasn't going through the bulkhead grommet so I sorted that.

I also found my OEM IAT sensor which is lower profile so will hopefully sort my issue with it hitting the bonnet.
(https://i.imgur.com/0kITSoA.jpg)

Next I spent some time trying to wire my reverse light. That was a fail. I need to look at this again as I had an auto. I have removed the park/neutral switch so I think the wire I soldered the reverse switch to is no longer getting power.


I also setup my HP EFI outputs to activate the cooling fan and the revers lockout. Both ended in fail. Not sure why neither are working at the moment.

Been getting through some more of my job list recently.

I sorted the horn wiring. For some reason I wasn't getting continuity between the relay and the horn switch so the horn was constantly on. Not sure why, but the wire goes through the airbag unit. Luckily I had threaded a few wires through my loom so I used one of the spares and bypassed the airbag unit.

I also sorted the reverse light. It took me a while to find the correct B/Y wire, but it's all sorted now.

I fitted my new straight terminals to the ignition leads and fitted them. I had planned to run the wires behind the headers for a nice tidy look, but decided against it. There was no point risking them melting and they aren't too unsightly in the normal location.

(https://i.imgur.com/9Rtw6ue.jpg)

Next was fitting the rad, cowling and intake.
(https://i.imgur.com/Fk2at89.jpg)

As always is the case with things, each time a sort a problem another arises. In this case the top rad hose doesn't really fit. I have ordered a 135 degree hose in the hope that I might be able to use two to form an s-bend.
(https://i.imgur.com/je3ZBJa.jpg)

I tried to fill the diff with oil but it turns out the drain plug has fused to the diff bastard! I haven't tried heat yet, but I am letting it soak a little first. Hope I don't have to piss about ordering a new rear cover.

I figured out why the reverse lockout wasn't working. I completely overlooked the fact that the ECU isn't getting a speed signal. So now I have to wire my Dakota Digital to the VSS and ECU input so that I can configure a speed input that can then be used to trigger the VSS lockout below 5mph.

SO what's left to do?

1 - custom exhaust
2 - heater piping
3 - Sort diff plug
4 - wire vss
5 - wire traction control (maybe after it's on the road)
6 - Plug gauges in (want to finished painting them first)
7 - fire it up and let it warm up so that I can let HP EFI do it's magic

Had a chat with someone I may get to do my exhaust. He is going to come over and take a look at the car and discuss options. Unfortunately he is now on holiday for two weeks.

I had no luck finding anyone that can bead roll my ali pipes so I hacked some crimping pliers. Not perfect but should be fine

(https://i.imgur.com/vTD7hnx.jpg)

Unfortunately, soon after that I got the grinder out and tried to modify the pliers so that I could bead the 16mm pipe I got for my heater lines. The tool is now ruined and I still need to bead the pipes :)

The tweaks continue:

Resolved the top coolant hose issue. Turned out to be pretty simple using a 135 degree silicone hose, 45 degree ali joiner and trimmed down the existing 90 degree bend.

Fixed the problem with the fans not coming on. Turned out to be two wires switched at the relay.

I drained the fuel in case it was that causing the car to run lumpy. It didn't look too bad as it was coming out, but as the petrol can filled it started getting pretty black. I hope it's just where it's been sat for 10 months. Last time I looked the tank was spotless so I am doubtful it's corrosion. Maybe I need to get a new seal for the fuel pump hat.

I spent a little time trying to figure out why my belt was getting thrown. It's not easy to tell but the pulley maybe on too far. Perhaps I ordered the wrong part number? It would be a massive pain in the arse if I have to swap it.

What type of rubber lines did you run inside the tank?  I would be concerned that something was not petrol compatible if I saw black coming out.  I would definitely pull the hat and see if you can wipe black off of any of the rubber bits including the seal, especially since you said the tank was spotless in the not too distant past.

Still on checked it out, but thought it might be where the furl had been sat in the braided hose. I drained the tank at the fuel rail so maybe it's that? Maybe anodising?

I took the cover off the fuel tank and it's still all clean in there. The rubber hose going from the pump to the cover looked a bit swollen and felt soft so I have ordered so Gates in-tank fuel hose. The hose I got was from a motorsports supplier and was definitely sold as submersible so not sure what the deal is with that.

An exhaust guy came over and took a look at the car. Basically he suggested 3" with two custom mufflers to make as much use of the space as possible. I've not had his quote through yet but I can't book it in anyway as I am still waiting for the replacement balancer hub to get delivered. I am also struggling to get the old one off.

I ordered some different texture paint for the interior plastics. It is sold as truck bed liner, but no way is it tough enough for that. It's pretty much the same as the last lot I bought but not as fine. It still marks easily enough with a scratch of a finger nail. Because of this I have now got a can of 2k spray clear coat (satin). Hopefully it won't react with the texture and will give a more durable finish. At £20 a can I bloody hope so.

The prep for this has taken ages but pretty much ready to paint them now.

I have spent a lot of time trying to figure out the heater hose routing. Originally I was going to use ali pipe as they go close to the headers, but I couldn't find anywhere to get the pipe bead rolled.

Now I have just gone with hose. Hopefully some heat sleeve will stop them from melting.

...continuation of small jobs like fitting wipers, securing wiring etc.

I tried firing the car up again but it ran like a dog. When I tried again later, it would fir up. Not sure what's happening here as a year ago it fired up and purred nicely.

I have checked that I have spark, but the plugs are black and wet with fuel. The car also smells really rich (which it didn't do last time).

Still investigating. I will try loading the old base tune up again to see if that works.

Yep, I got a log whilst I was trying to start it. I am not really sure what to look for though. It isn't detailed enough to show individual cylinder readings or anything. I checked the oil and fuel pressure and the cranking RPM (max was 300rpm).

I had some mild success getting the car running. It looks like the issue lies with the throttle plate screw.

My iac readings were at about 90% when they should be 10 or less. I didn't get it settled that low, but got it to idle at least.

Whilst I was under the car checking on the handbrake, I noticed that the fuel return line may have been leaking. The protective piping I put around it was discoloured. The actual fuel line was swollen and soft so I spent too long swapping it out. Now I know why people relocate the FPR.

Not sure what the deal was with the old hose but I swapped it out with some decent stuff.

So, it's been a while. I had been fiddling about with my tune trying to understand how it all works and trying to get rid of my idle surging. After a while I gave up and decided to get someone to help me. The idle surging was cured (when warm) but at cold idle the issue is still there, all be it not as bad.

Anyway, I finally moved it under its own power. I didn't get out of first, but it did move.

I noticed 2 issues. One was that when I put it in reverse, it jumped out. It only did this once, but when engaging reverse it's really hard to tell if it's engaged properly. Maybe I just need to get used to the box?

The second issue, which needs to be solved before I can get it on the road, is that the abs feels like it's coming on whenever I use the brake. Not really sure what would cause this.

After having looked at that I think that is a different issue. I don't have a problem moving the shifter into reverse (I have the lockout wired up), it is more like the reverse isn't engaging properly. However, it might be that by disabling the lockout again, the spring actually holds it in gear.

So had another little play with the car today. I had to adjust the throttle plate screw a little as it was previously adjusted without the air filter on.

Anyway, good news is I don't think there is a problem with the ABS. The bad news is, when I jab the brakes on (we are talking less than 5pmh) there is an almighty bang/thunk coming from the front right of the car. I suspect it's either the brake, bushing or maybe drop links?

I don't have time ATM to jack the car up and have a look.

The other issue I still have is that the revs hang when I come to a stop (engine up to temp).

Checked the suspension today. I couldn't find any loose bolts, but it felt like there was a bit of play in the lower control arm ball joint. I took the arm off and the ball joint does feel pretty loose compared to my spare set.

Problem is, my spare set hasn't got any bushes so now I have to order and fit some new ones.

The only other thing that had a little play in it was the track rod end.

another thing I forgot to mention, though not that big a deal at the mo, but I get clicking noises from the starter nearly everytime I start it.

I'm not sure if I have hurt my battery by charging it frequently or if the starter is on it's way out. I am using a Westco MX5 battery. This still happened after using a ctek charger on a service charge.

How many CCA does the battery have? I know some have used them in the past but it's a pretty tall order to start a higher compression v8 with such a small battery. I use an optima 51r (450 CCA) and it's ever so slightly on the small side for my motor. The first couple rotations are a little slow. I'm at 11.56:1. When it was stock 10.1:1 it didn't have any issues.

I'm actually going to be building my own LiFePO4 battery which should have around 600CCA and run a little higher on the voltage. The only downfall is cost and reduced Ah capacity. I'll be around 20Ah vs 38 on the optima. Weight should be around 5lb though.

Well from what I can see its 475CCA.

It was working fine when I first got it but has been drained flat a few times now.

Its either that or maybe the new tune?

my car was having a slow start, the battery i had was drained a few times like yours but still read 12.5. I replaced it anyway and its like night and day. Also adding a heat blanket to the starter, power cable, AND the cable from the alternator completely resolved my slow HOT start.

I used the hose that came with the rad and cut it, then joined them with some ali pipe. Nothing special about it. The only thing to watch out for is that the fitting on the rad is a different size to the fitting on the pump. It was a little lose on the rad so I got some high torque clamps to make sure it sealed.

Had some time off so I painted my wheels black (badly as they are not worth much).

Had another play with the IAC settings and the engine doesn't appear to hang now, though it's a lot warmer than it was when I tried before.

The knocking noise for the front right is still there though it appears. I only heard it when I was braking after reversing this time and it wasn't as bad. Still want to know what it is though.

I have an issue with the knock sensor reading 100% all the time, but I think that is down to having the wrong settings. I will test this tomorrow.

The car appears to start a lot more easily now that I adjusted the cranking timing back up (from 5 deg to 15 deg IIRC), but again, it is warmer out.

Cold running is still a bit rough but I think I am at a place where I can book an MOT.

Bah, got to the MOT center and the car is too low to fit on the ramp so I have to find somewhere else to get it done (or buy some coilovers).

Driving it bought to light a few potential issues though.

1 - the handbrake light isn't going out not
2 - There is some pretty major bucking at low revs in 1st and 2nd (not sure about 3rd).
3 - It still smells really rich, which is worrying for the emissions test.

Fitted the coilovers now. Its so high it looks like a 4x4 :)

Some shit news too though, I have found that my steering rack boots are ripped by my anti roll bar, which is an MOT failure.

I also found that the crankshaft seal appears to be leaking. I assume that it got worn when I fitted the incorrect hub that Ati supplied me. This has pissed me off as it's a ball ache of a job and I've already done it twice.

Rear left brake lights not working appears to be dodgy bulb terminals, so no big deal.

The fog light is working, unless there is a requirement that he light works even if the tail lights aren't on?

As for the ABS light, I took the bulb out and tested it and it appears fine. It's too cramped under there to test the board for a voltage. Might have another go tomorrow.

Failing that not sure what my next step is.

The ABS bulb and fuses are fine (I have started another thread about this). In the process of giving things a look over I noticed that there has been a leak on the top of the ABS pump. Looks like I didn't tighten 2 of the lines down properly.

So it's been a while.

I found out that my coolant setup wasn't quite right. Ihad a valved cap in my rad which meant when the water from the howe tank came down, it couldn't get in to the rad.

I couldn't find a high enough pressure cap that wasn't valved, and I didn't want to go through the hassle of getting my rad welded, so I did this:

(https://i.imgur.com/oU2HEjz.jpg)

(https://i.imgur.com/EexQyiq.jpg)

(https://i.imgur.com/jwHDRCU.jpg)

Tried to get it MOTd again, but because of the coolant leak, the brakes need bleeding again and the bucking is pretty severe, I cancelled.

Next stop is to book it in for a tune.

I did get RB dual tip exhaust though. I am taking welding lessons at the mo so I am hoping that I can ditch the exhaust I got made, and repurpose the Hinson y-pipe and join it to the RB backbox.

Been very lazy recently, but got myself a few things:

It was bugging me that I didn't have a check valve for the fuel pump so I got this. I've ye to fit it but it looks like it may give me a few problems to solve as it is way bigger than I expected.
(https://i.imgur.com/FpPhEPt.jpg)

I also got a pair of 3" cats. This is a bit premature as I have barely done any Tig welding yet, but I thought I would get them whilst they were discounted
(https://i.imgur.com/fqjdgr5.jpg)

As for the rest of the car I have had some 10mm spacers made in an attempt to fit the stock strut bar. Nearly there with this but needs some fine tuning (I think it is slightly touching the intake).

In terms of getting the thing on the road, I need to sort the bucking. My plan now is to jack up the rear of the car and see if I can recreate the bucking at low speed and under no load. If I can then I will have a tinker with the timing and/or AFR to see if I can get it to a point where it's driveable.

Oh...I also spent ages relinking all my thread images. Thanks Photobucket.

Post by: Gunnytron on January 07, 2018, 11:55:11 AM
Some pics of the strut bar. It's still pretty close, maybe 3-4mm between the strut and the intake. This could be increased by bending them mounting points some more.
(https://i.imgur.com/PtlwMO6.jpg?1)

(https://i.imgur.com/Nv8wkVC.jpg)

(https://i.imgur.com/aneqXxN.jpg)

As predicted, the check valve is too long to allow me to run the hose barbs. I will have to see if I can get an extended female-female fitting or use a standard joiner and move the pump a little higher up in the tank.

I wonder if Swagelok would have an adapter that could help out in fitting the check valve?
The nice part about their compression fittings is the easy length adjustment.

Another option could be to use AN flare nuts and flare a short piece of stainless tubing to the specific length you need.  The hard part may be finding a 37 degree flare tool, but I'm sure they're out there.

I did look at flare nuts but I think the fittings are too close together. I don't think there would be enough room to flare the tube. There's only 50mm from the base of each of the fittings.

Well that didn't work. It was 5mm too long. Plan B is to raise the bulkhead fitting up so that the bottom of the AN fitting is flush against the bottom of the hat. This won't be massively secure as there will be nothing clamping the hat from the underside.

Took the car out to try and sort the ABS (see my other thread) and bucking issue. I was hoping that the bucking issue was to do with acceleration enrichment, but it didn't really make any difference.

I also STILL have an issue with my cooling system. My rad cap setup is leaking so I need to check if I have my system setup properly.

Two steps forward one step back.

(https://i.imgur.com/ylvTvEt.jpg)

I decided to get my rad welded up so that I didn't have to worry about my dodgy pressure cap mod leaking.

I also had a few other things I wasn't happy with such as the heater hose routing through the front bumper and the leaking crank seal thanks to ATI sending me the wrong hub.

So it was rad out so I could kill a few birds with one hammer.

I decided to hack the Hinson rad up to keep it looking clean. I will get it welded up with the addition of some tabs so that I can mount a front and rear shroud. I made the rear shroud, but I am not convinced the fan I have is going to fit after I put this on. It will also give me the opportunity to paint the rad black. I got the paint to do it years agao :)

Got the crank shaft bolt out tonight. Always scary. It was covered in oil, so I guess it's good that I am doing this.

One thing that concerned me though is that the oil smelt of fuel quite a bit. I am hoping it is where the car may be running rich or because it's been standing a lot. Just hope it isn't blowby.

Crank pulley is off and I have cut some tabs to get welded to the rad so I can get that sorted soon hopefully.

I took off the front cover and knocked the seal out. One thing I did forget the first time round was that the are where the seal sits is damaged. In light of the fact I am having issues with leaks I think it's best to get a new cover. This is a pain in the butt as it takes ages to get stuff from the US... but what's new.

My crank shaft bolt finally turned up, so I put the car back together.

I got the rad back in and, as expected, the fan now overlaps the shroud too much. The two options I have are ditch the shroud or find alternative fans. A dual, low profile fan setup would be nice, but I have no idea which to get (spal aren't readily available over here) and don't really fancy spending the money.

Re the heater lines for rhd, the existing single Mazda hardline works well and will connect straight to the smaller pipe on the LS pump with one of the hoses used at the bulkhead which are still available from Mazda.  There is not enough room to run a second hardline so we used a 90* hose straight off the larger pipe on the pump and routed it underneath the throttle body to a hardline we made up in Al that runs along the chassis then bends up towards the bulkhead.

I tried running a second hardline to follow the standard mazda one, but I couldn't get it to work right, I also tried using a second mazda hardline but still is wasn't right.  In the end I followed the route suggested by radiomike but used a hardline going across the engine, it sits on top of the water pump and underneath the steam vent tubes.  It exits near the PS pump, then into a 90* rubber bend, then to a hardline along the chassis and then into another 90* rubber bend to the heater matrix connection.

When I get a chance I'll dig out and post some photos.

Sounds tidy. What diameter pipe did you use?

My current plan is to simply run rubber hose forward to the rad, across the back of the rad, then along the opposite chassis rail to the bulkhead.

I dont have the tools to make hardliners. That could change if course :)

16mm Al, I managed to borrow a 5/8" mandrel die for the afternoon and bent it by hand.

How did you make the barb?

We ordered the pipe with rolled barbs at each end but they had broken the tool and supplied a plain pipe.  It is possible to form them with a pair of grips that have been carefully ground to the right shape but we simply put the pipe in a lathe and made a cut about 1/2" long and about 10 thou deep 1/4" from the end of the pipe.

I managed get some time to upload some photos, these are my attempt at a second hardline following the factory line, but I wasn't happy with the results.  The alu pipe I used had an OD of  16mm with an ID of ~12mm.

This is the final arrangement where the it cross's over the front of the engine between the water pump and underneath steam vent line

Cool. Thanks for the pics. I have bought a pipe bender and a flaring tool and some 16mm Ali. I had to modify my pipe bender as it was 15mm so puy with the grinder.

I am intending to run the hardline under the water pump to the frame rail.

That is exactly the route that we used above the water pump except we did it with a flexible hose.

What headers are those?

That's where I go the idea from.

I made the headers myself, I mocked it up with waste pipe and bends and had a company bend the tube to my spec, and they made the 4-1 merge collectors.  Not all of the angles came out perfect, and it was a pain routing it via the starter motor and steering U/J's/ column.

Pictures to follow, but I have now finished the heater hard lines.

I ended up buying some 16mm ali and then getting a pipe bender which was 15mm. That 1mm was enough to mean the ali pipe wouldn't fit, so, I got the grinder out and modified the bender. After that it worked great.

I tried making double flares with the pipe flaring tool but it wasn't going to happen. The ali is too tough, even after I hit it with a torch. Single flares were easy though, so I just did that and then sanded the rough edges down.

I also put a new sealed plug in for the fan as I wasn't happy with just using spade connectors. Unfortunately the fan appears to be blowing rather than sucking.

No leaks though so that's something.

Went out for a few laps of the block today.

Brake issue is definitely fixed :)

It is also the first time I have come back without any coolant leaks :)

As far as I can see, no leaks from the crank pulley area :)

Also, the bucking is way better after changing the IAC settings :)

The fan direction was easily fixed by switching the pins on one side of the new connector :)

Now, a few things that concern me:

1 - I am on my second Westco MX5 battery and it is struggling to turn the engine. Lots of clicking before it starts. After ruining the last one I have been pretty careful not to let this one go completely flat and regularly charging it with my ctek charger. I now need to decide if I should get a larger battery or try another Westco one. For the moment I might get a big cheap one just so that the tuner doesn't have issues starting it.

2 - When idling with the car out of gear and foot off the clutch I can hear the gearbox whiring. When I put my foot on the clutch the whirring stops. It appears to struggle to engage first also. This isn't because of the valve thing (I forget what it's called) as that is controlled by my ecu). It shifts easily enough, but doesn't always engage. It makes it really hard to tell if I am in gear or not.

Here are the lines exiting the water pump.

They go under the water pump and exit here:

Then follow the frame rail

I absolutely love mine.  Try not to ever let it die - unhook the battery if the car will sit.  If you kill it the battery won't come fully back.

You can't trickle charge it.  I bought their charger and it has never worked right for me.

I'm going to try an ultracapacitor bank in parallel with a small gel-cell battery for my road race car.
The caps should give the current for cranking, and the battery will hold enough reserve to power up the electronics, pumps, fans etc. before starting.
It should also boost the caps back up very quickly in case multiple cranking events are necessary.

Overall, it should be much cheaper than Li-Ion, and not much heavier overall.

I like the undertray!  Been considering making one out of 3mm aluminum.  I've punctured an oil pan due to a MASSIVE boulder in the road before (~softball size rock, but boulder size relative to an FD lol), and I've scraped the oil pan on surprise bumps in the road when I've bottomed the car out.

The oil pan puncture was a massive disappointment.  Was not in a great mood at my girlfriend's Christmas dinner once I finally arrived.

Busting the pan is something I am concerned about. Firstly because it takes ages for anything to come over from the states, secondly it cost a small fortune.

This isn't designed to protect the sump as it is only 3mm dibond. I guess 3mm ali plate may work, but I would have thought welding some plate to the subframe would be better.

Could weld on tabs and bolt a plate to the subframe, but you wouldnít want to weld it permanently just in case you do want to get the pan off.

Seeing as the main power cable casing had started to blister, I got some heat wrap for it
(https://i.imgur.com/a6uoqz7.jpg)

I aso spent way too much time sorting this brake stopper out. It is made Super Now and came no where near close to fitting. Maybe it's because I had an auto or a newer brake master. Maybe it's a knock off?

I had to use a slimmer locknut, take 2mm off the back of the stopper pad and custom make a new mounting arm out of ali angle. You can see in one of the pics that the supplied one (orange) was no where near the same angle.

And because I didn't want part of it silver I stripped all the anodising off and painted it. I also put a small bush in the mounting hole as it was way too big for the stud on the car.

Now that I have painted and fitted the rad I can see there is a leak where the welding was done so I have to take it back out, get it rewelded and paint it again  >:( I will try and do a little pressure test with a foot pump first, just in case there are any more.

I finally got some wheels. 17" SSR/Desmond Koenig KG-JPN 3-piece split (not welded). One pair are 17x9s and the others are 17x8s so I am going to get some larger outer lips to make them 9.5 et22 (for the rears), I think they should fit OK.

After refitting my rad, I have noticed that it actually leaks more than it did before I got it fixed. Not impressed  >:(. There's little point going back to the guy that welded it so I will have to try and find someone else.

Made some progress with the under tray. Made a couple of brackets that I riveted to the bumper so that I can use rivnuts to secure the undertray.

Weighed the 9.5s and they come in at a little under 9.7kg. Not bad.

This rad is really getting me down now.

I got project Binky on it and marked the leaks. I then applied the solder but the leak just appears to be flowing under it so I ground all the solder off and leak test it again and it appears that the leak is coming from underneath the bracket (kind of hard to explain). There is no point putting solder on it as I think it would be impossible to get a good seal all the way round.

That means that I am going to have to grind the bloody bracket off, try and find then fix the leaks, then solder a new bracket back on.

The main problem with this is that when you grind the ali it has a tendency to block the holes enough that you can see where the leaks are.

PITA!

You shouldn't grind aluminum anyway, it cloggs up the emery wheel, and can cause the wheel to violently explode when the embedded aluminum heats up and expands.
People have been killed from this.  :o

Use a disc or belt sander for aluminum, brass and other soft alloys, as they don't clog up like a stone will.

I wasn't aware that Aluminum could be soldered.  I thought it had to be welded.
Good luck finding and fixing the leak.

So I got over my tantrum and ground off the bracket (using a flap disc ;) ). I then  drilled out where the leak was and filed it with the solder.

It appears to have worked quite nicely. I wish I know about this stuff years ago.
