Title: Esser's LS3 FD RX-7 R1
Post by: Esser on November 28, 2017, 01:18:15 PM
I figured I would post up what I have been working on over the past year. I have owned several import cars in the past including a couple 350Z's and a few 240sx's and recently started diving into the LS world with a C5 corvette. The vette is a fantastic driving car and makes great power very little money, and unmatched reliability. However, there was always a lack of interest for me in the body and interior side of things, as well as the community in general. The 90's era imports have a special place in my heart, and the ability to create a car with the monster V8 power and reliability in a lightweight chassis peaked my interest. Enter the FD RX-7.

For the longest time I have wanted to pursue a project with an FD and it wasn't until recently that i was able to jump on a deal for a roller chassis from Texas that I found on this forum. I had my mind made up before I even bought the car, that an LS would find it's home in the chassis. It was a perfect candidate: R1 model with low miles, fresh paint, and all the rotary shenanigans had already been pulled out. I do love a nice rotary, but for me this project is about making my dream car, which is an LS FD. All the benefits of the reliable torque from a V8 and the elegant, agile chassis of the rx-7 combined into one. After a trip down to Texas (a 12 hr drive) I had the project strapped on a trailer and on its way home. :2f2f:

The R1 model was a must for me, at 6'1" I was unable to fit a helmet on in a sunroof FD. Not to mention the roof line without the sunroof has a slight dip that adds to the unique curvy look of the FD. The roller I found was extremely complete, with all interior items included as well. I am thankful I was able to find such a clean slate to start with.

Here is my Tacoma making the long haul from Texas back up to Indiana with my precious cargo. It was a great feeling looking back into the rear view mirror to see that FD back there!

Fresh off the trailer after a second 12 hour trip and resting in front of my house:

I was able to start looking through the engine bay and seeing what all else had to be done, and the hours of research had begun to prepare myself to install an LS3 into the chassis. My overall plans for the build are to do it once and do it right, my OCD will help keep my cleanliness of the build in line. Ideal setup will be for a road course, but would like to keep it as streetable as possible.

Wow, that's a pretty looking chassis to start with!

Here is a good size comparison next to a C5 corvette, for those curious. It is indeed much smaller in length and width!

My first plan of attack was to strip out the chassis and remove everything in the bay to prepare for paint. This involved pulling that horse show front harness out (huge pain) and taking out all the factory brake lines. this engine bay has been painted previously, but it was done when the engine was in the car so it is somewhat of a patchy mess ha.

Rolled it out and removed the dash to get to some of the wire harnesses a little easier. The dash removal alone took a couple hours

HVAC system removed:

Got the front down to bare chassis, in an attempt to start to fill in some holes and do a slight shave of the bay. I don't plan to completely smooth everything out, just a slight clean up.

Man, that's a really nice looking roller you have there.   8)

Sounds like you'll end up with a top-notch swap with this car.  I look forward to seeing its progress.

With everything removed from the engine bay, I was able to give it a good cleaning and started removing some of the unnecessary brackets and holes.

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

(https://i.imgur.com/lQUdgmv.jpg)
(https://i.imgur.com/Ohd4Z6R.jpg)

I also siphoned out all of the old gas that was sitting in the tank for who knows how long.
(https://i.imgur.com/n6K5Hs1.jpg)

With some help from a buddy, we welded up a lot of the future un-used holes for a bit of a shaved look:

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

Again, not going for the completely shaved look, just removed the un-used holes so the engine bay is simplified. I grinded everything down and hit it with a coat of rust reformer to keep everything minty until the painter can get ahold of it.

I removed the pedal assemblies and tore them down to rebuild them. It's obvious they used mild steel on these, and a light coat of rust had formed on the surfaces. I ended up soaking everything in apple cider vinegar to remove the rust, which worked amazingly well. I let them soak overnight in about a gallon of it, and they came out looking super fresh! I dried them off and before it could start rusting again I hit them with a coat of rust reformer.

I figured I would go ahead and freshen up the suspension components in front and undercoat the wheel well areas before the car goes off for bay paint. I removed the front a-arm/brake assemblies and gave them a good cleaning. Everything up front is super pro bushings, and Tein flex coilovers. Debating on if I should do a brake upgrade now or down the road.

Had to pressure wash and scrub the crap out of these wheel wells to get all the crap out:

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

I used 3M professional rubberized undercoating and layed down a few coats. Love that stuff.

Re-assembled everything and the tow truck came to take her away to the paint shop:

Body shop planned to knock it out in a week

That is very clean slate to start with!  Build it with street use in mind, if your road racing idea takes off its much easier to remove stuff then to build it for road use and have to try and add it back in later to make it a killer street car.  The lines of the FD are so awesome!  I just stare at mine in the garage sometimes.  Its my dream car for the same reasons you bought yours!

Can't wait to see your review when you get it done!  You doing crate ls3?  My advice is to cam it before install, get the most of those heads right out of the shoot.

Thanks I was lucky to find such a clean roller, it has made working on the car a pleasure since everything is fresh. I have thought about doing a cam, but it may further down the road. I enjoy stock cam behavior quite a bit, until it bores me I plan on keeping this cam in at least for a while to break in the engine.

Chassis has 91k miles on it. The fresh paint makes it look like a lot less.

So unboxing the crate LS3, such a nice looking motor! I thought about buying a used for the longest time, and some deals fell through on some engine/trans combos. I eventually settled about ordered a brand new crate engine, it was not much more money than what used LS3's go for, and of course still has the GM warranty on it.

Got it up on the stand and started taking about the brand new engine to do the oil pan swap

I will need to be using an f-body oil pan for the steering rack clearance. I went ahead and also bought the Improved Racing oil pan baffle for the added insurance during some hot laps.

Something that I put on my last LS engine was an ATI dampener, it saves some weight and has a 10% under-drive on it. Will be a great piece to obtain that "quick rev" action i'm going for.

(https://i.imgur.com/y3Ywsp5.jpg)

Pulling the stock on off with a puller:

(https://i.imgur.com/kaj3OtT.jpg)
(https://i.imgur.com/JH8nEPI.jpg)

New one is on! The new balancer weighs about 4 lbs where the stock one was about 10lbs. I went ahead and removed the stock manifolds as well since I wont be using them. I decided to go with the Samberg/Ronin subframe assembly, so I installed their fabricated engine mounts. They look really well constructed!

Car came back from the painter looking amazing, the pictures don't do it justice. I started installing all of the brake components when I got it back.

(https://i.imgur.com/s5pzZlI.jpg)
(https://i.imgur.com/WHfTWaq.jpg)

I went ahead and deleted the ABS system, for weight savings and the appearance factor. Not to mention I didn't have any of the sensors and I didn't want to put money into getting the system working. I chose to do the Rotary Shack's hard line abs delete kit, it took some manipulating but ended up fitting great. Installed a new gasket on the Booster and got it fitted up.

Great looking build and nice start to your build thread!  One piece of advice is to make sure you do a good job insulating your tunnel (you might already be planning this).  I used Lizard skin on the underside with custom aluminum shields on the passenger side to match the drivers.  I know a bunch have guys have used the DEI adhesive backed stuff with good results as well.

Thanks, ended up getting a bunch of the DEI adhesive tunnel shield, I did end up keeping the original shield that goes down one side of the tunnel already.

One of these days I may do a full interior removal and lizard skin the inside!

The previous owner of my car used a bunch of tar paper insulation...some kind of budget dynamat.  It can't hold up to the heat.  It is continually melting onto my exhaust and transmission and making a mess of absolutely everything.  The smell is horrible.  It is nearly impossible to remove.  I spent hours with a heat gun and scrapers trying to get it off last time I had my trans out.

An undercoat or fixed heat shield is my recommendation.

You're really making me consider doing some engine bay clean-up myself next time I have my engine out.  Very tempting!  My bay was painted right before I bought my roller but they didn't do a fantastic job by any means...

One of my goals fr the project was to get the engine bay "show worthy". Not only does it look good, but it makes working on the car much more enjoyable when things are nice and tidy.

I took some of the advice from Halfspec's build and went with the Toyota Landcruiser master clutch cylinder. It took minor modification to fit, and I did not end up doing any welding. I used the male to male thread pitch adapter and everything looks like it's going to work. The master cylinder itself is cast iron, should be pretty stout if the seals hold up over time.

(https://i.imgur.com/jZTsks8.jpg)
(https://i.imgur.com/RTW4agk.jpg)

I installed the lines, and started working on the subframe. I went with a setup from Ronin, and had the subframe powdercoated from them. Install went okay, I did end up having to grind down some welds on the top of the subframe so that it would sit flush to the chassis rails. I used my grinder and took off the bumps of the welds and all is good!

I had seen some reported failures of the samberg subframe camber rings breaking off. This was mainly due to other root causes such as the front camber bolts loosening up and allowing movement. I requested that Ronin beef up mine with some extra welds (Thanks Ronin!) and they provided. They put some extra beads around the perimeter of the ring.

(https://i.imgur.com/WoP19Wc.jpg)

In addition, I etched in some lines on the back faces of the bolt face to help "grab" the metal on the subframe. When this gets tightened down it should help hold the alignment during hard driving/bumps.

I started working on the fuel system. I had previously emptied the tank, and had no clue of the condition inside. Being a metal tank, the possibility of rust was there, but once I pulled the stock pump I saw that everything was minty fresh!  :)

I installed my new fuel pump: a Walbro 400 lph. Should provide plenty for the LS3 even when I do some bolt-ons and cam and such.

I did decide to go ahead and use all new fuel line instead of re-using the factory mazda hard lines. I got a big box of all my aeromotive items:

I went 6an for everything and put the fpr up front return style. Mounted it right by the master cylinder.

Removed the tiny fuel outlet/inlets on the factory tank cover and replaced with 6an bulkheads:

It was difficult to find a place to mount the huge aeromotive fuel filter, this thing is like the size of a soda can. Should flow excellent. Only spot that would really fit it was the factory filter location above the diff:

Really nice work so far. If you haven't installed the motor yet I'd suggest rivetting on the DEI heat shield, mine wasn't really sticking super well with the adhesive on its own.

Dig the wheels by the way.

Trans has arrived! I went with a Stage 4 T56 Magnum. It is a new unit that has been torn down down and had carbon blocker rings installed and bronze fork pads installed. It's rated for 900rwtq! This one also has a Fbody tailhousing installed for ease of install into the FD chassis.

Started wiring in the engine. I went with the PSI conversions wire harness. Quality seems spot on and price is great compared to all other harness manufacturers. I 3D printed a hole size reducer so that the 2inch firewall grommet on the harness would mate up to the existing 3inch hole on the FD firewall.

My fuel cross over happens after the strut bar, and the strut bar clears the intake by about 1/4". Your engine may be a bit too far forward? I can get more pics of mine if needed.

I had to clearance my strut bar as well with a factory LS3 intake.  It bolted down seemingly fine until I saw the interference.  There was about a 1/4" that needed to be relieved.

I was able to get some more wiring done, and installed my starter.

I probably over did the heat wrapping, but better to be safe than sorry I figured. I wrapped all the wires that will be anywhere near the headers, and created some brackets to tuck them in close to the block.

Moving the expansion tank to the interior is going to make it tough, if not impossible, to properly fill and burp the cooling system.  Also, your interior will always smell of coolant.
The tank needs to be the highest point in the cooling system, and the lines to it cannot have any dips or peaks to trap air bubbles.

That makes more sense, but the longer lines will still need a constant slope to the tank.   :cheers:

Title: Re: Esser's LS3 FD RX-7 R1
Post by: Esser on December 18, 2017, 02:58:54 PM
I have done a full conversion to speedhut gauges, and thought I would share my process. I posted this DIY in the electronics section as well, figured I post it in my build thread. I was able to retain all the factory housings and bezels for a complete stealth look. I did all of this in about 3 hours, and no major fabrication was necessary for an OE look. First of all, you will need to order these sizes:

4.5" Tachometer
4" Speedometer
2-1/16" Oil pressure
2-1/16" Water temp
2-1/16" Fuel gauge

I have seen a lot of people order the smaller 4inch tach, or get the 3-3/8 speedo. Dont do this. I actually measured the holes, and the 4.5" tach and 4" speedo work perfect. They actually measure out almost identical to the diameter of factory gauges. Trust me.

So for those of you that dont know, the speedhut gauges include their own bezel (usually aluminum) and their own rings to mount them. They also have a button (if programmable) and their own plexi-glass window. We will be ditching the plexi-glass window and aluminum bezel in order to make the factory mazda pieces work.

So here is how the speedhut gauges look compared to the stock ones:

(https://i.imgur.com/JNPQITf.jpg)
(https://i.imgur.com/yacN6h6.jpg?1)

I went with the Revolution style gauge with white font. I also had the custom lettering put on to say "RX-7" ($10 option)

First step is to remove the cluster obviously and unclip the clear lens cover and the black plastic backing from the cluster assembly.

You will be left with this:
(https://i.imgur.com/dEE3DSX.jpg?2)

The stock gauges themselves unbolt from the back. There are about 3 bolts per each of the gauges. Go ahead and remove them so that you have an empty piece of white plastic (don't mess with the circuit board paper on back, we need to retain this for the turn signals) but you can go ahead and start removing the larger bulbs that screw in from the back.

Now looking at the black plastic gauge housing, you will notice that these holes are way to small for our large gauges. I used some side cuts and started making cuts into the edges of the housing. This effectively opens up the holes for the larger gauges. Then I literally threaded the gauge body into the housing. bottom them out until they sit flush at the front.

(https://i.imgur.com/bQJxC8N.jpg)
(https://i.imgur.com/tUg05jQ.jpg)

Dont worry about being neat, this cant be seen. Gauge will "press/thread" in:

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

Tach installed: notice the aluminum bezel is removed and the slider ring on the back is also ditched.
(https://i.imgur.com/z3YnulG.jpg?1)
(https://i.imgur.com/ENetmPw.jpg)
(https://i.imgur.com/RriRhWC.jpg)
(https://i.imgur.com/2kx4UB3.jpg)

Remove any interferring white plastic standoffs on the base of the cluster. These will be obvious when piecing it together.
Run the wires through the (now) un-used bulb holes:
(https://i.imgur.com/eAfaQee.jpg)

Once all the gauges are pressed in, I noticed that there are stubs on the edges of each gauge. I will need to drill out the clear lens to accept these protrusions. I put a bit of toothpaste on the tip of edge stub and then lined up the lens so I could see where I needed to drill:

(https://i.imgur.com/O7YFsPc.jpg)

The "drill here" mark it made on the lense:

(https://i.imgur.com/SHgP2R8.jpg)

At this point you can re-install the lens and see that everything fits and lines up like OE

(https://i.imgur.com/VjrdW6H.jpg)

But then you will realize that you can't push the buttons on the programming for each gauge. I marked "eye-balled" where each of the buttons were with a sharpie, then removed the bezel and drilled it out to accept the speedhut rubber buttons and standoffs.

Drill slowwlllyyyyyy:
(https://i.imgur.com/AmgCh1e.jpg)

Buttons installed:
(https://i.imgur.com/U0BnJPh.jpg)

Standoffs put in place to reach the button on the gauge:
(https://i.imgur.com/Nq4WJ7P.jpg)

Screw all the items back together and you now have a fancy factory looking gauge setup:

I like my speedhuts.  I wish the temp gauge was more accurate...I don't know why it doesn't always match the ECU.  Maybe a group loop issue or something.

My favorite feature is the GPS altimeter on the speedo.  It's like a horsepower meter haha.

I like my speedhuts a lot. I have had one slight issue on the speedo, it flashed between time and weird numbers sometimes. I contact speedhut and they said it can be warranted at their cost for shipping both ways. 

I haven't found my temp gauge to be off that much at all, within +/- 5 degrees as compared to the PCM.  I would suspect this has to due with temp sender location rather than the accuracy of the gauge.  And really, who knows which is accurate without doing a controlled test.

I also completely took apart the HVAC and cleaned out all the debris. My roller is low mileage, but still had a bit of leaves and crap in the vents:

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

I did some relocating, and I think I found a better spot for the expansion tank in the bay. It tucks into the corner by the wiper motor pretty well. I temporarily set it here to see how the hose routing will work.

(https://i.imgur.com/eGcWgf6.jpg)

Heater hoses ran, and covered in some fiberglass heat wrap from RaceFlux.

(https://i.imgur.com/cxUdqWx.jpg)
(https://i.imgur.com/igIqU4F.jpg)

I also found a nice overflow tank and fabbed an aluminum bracket for it to sit back in the corner next to the expansion tank. Will have to go back through and clean up all the hoses, but I think i'll stick with this setup. It get the expansion tank in the highest place possible for coolant burpage.

Gauges all wired up and installed. I do not have any of the circuit board from the factory speedometer, and it appears everything functions. All the stock lights still illuminate and the turn signals work fine. All HVAC controls and everything function. It is safe to delete that board when replacing the speedometer with speedhut.

Finally had a warm weekend so a lot of progress was made. I had to remove the intake again in order to get the speedhut oil pressure sender and adapter installed. I also had to slightly trim the firewall lip to help clear the wire harness.

I bought a cheap Pioneer radio to install in the empty hole on the dash, and wired it up. To my surprise the retractable antenna works still.
(https://i.imgur.com/SNROusQ.jpg)

It was time to fill up the coolant system. I used a AirLift system, which vacuum fills the entire coolant system. I pulled a 30in vacuum on it and it took about 3 full gallons to fill. Zero bubbles and no need to burb the system with this method!

Here is a link to the airlift tool:

https://www.amazon.com/UView-550000-Airlift-Cooling-Checker/dp/B0002SRH5G (https://www.amazon.com/UView-550000-Airlift-Cooling-Checker/dp/B0002SRH5G)

It works by hooking up a valve to the radiator cap that creates a seal to the system. The valve has two attachments on it: a venture, and a "straw". When you hook up compressed air to the venturi it starts to pull a vacuum on the system, up to 30in hg. After the needed vacuum is pulled, you close the valve and disconnect the venturi and hook up the "straw". Make sure the other end of the straw is in your coolant source and open the valve, the vacuum will suck up all of the coolant until the system is full. When done correctly there will be ZERO air in the system.

It's getting close!

I started re-installing all of the factory panels and bumper, it took some time to get the body lines correct again. I decided early on that I would delete the factory hood latch, and went with an aero catch setup. The install is a bit of a pain, but I was able to do a clean setup.

Started by drilling a 1.5 inch hole and working off of that.

My little drill pump jig works will, I put a clear section in to see the oil going through to make sure you're pumping. I will have to upload a video, but the engine fired right up on the first attempt! It's almost ready for the first drive, just have to do a quick alignment in the garage.

It works really well. Just have someone turn the engine over by hand while putting pressure into the system, and it will get oil up into the lifters as well.

Nice install on the hood latches.  Why did you want to remove the factory latch?

My factory latch was sticking when I bought the car, and I didn't feel like keeping that hunk of metal up there. Not to mention my painter filled in the hole for the cable lol. I figured I would ditch it in the future if I ever got an aftermarket hood so I went ahead and did latches. I'm glad I did, I like being able to open the hood without having to go into the car.

Bunch of photos! I was able to wash the car for the first time in a year. It moved out under its own power, very promising. Clutch grabbed great, but I lost brake pedal pressure. I think my master cylinder is just bad, it grabbed a little then went to floor like it blew out a seal, got a new one on the way. Bunch of pics in the decent weather! The paint still has zero miles on it, shines up great.

This is the straight through sportsman muffler. I was looking at the multi core but it was almost $400 for just a muffler and that was a little steep for a couple db's. I fired up the car with the setup currently and was surprised at how tame it was, the addition of the last muffler should make it about perfect im hoping.

Nice build man, I can't imagine how quiet it will be running 2 mufflers.  The blue SI out front brought back memories of when I first started building mine, I had a Vortech supercharged black SI.

I finally got into my appointment at the tuner. I drove the car around for about 100 miles to get things broke in, changed oil, then headed to the dyno tune!

It put down 382hp, which is right in line with what most stock LS3's do on the dyno. More importantly it drives perfect, even with the aggressive RXT clutch. Torque is everywhere!

Thanks for the comment, there is not a whole lot of Import support around here that's for sure. Everyone who see's my car has no idea what it is but they love it haha


Got a lot done this past weekend!

First I swapped out to the newer style 99 spec taillights. They do give it a more modern look, and are more suited to the typical RX-7 jdm look. They are also brighter.

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

I then adjusted ride height to about where I wanted it and went in for an alignment, made such a huge difference in the way it drives. I had attempted to align in my garage with tape measure but I can only get it so close. Once it was on the rack we could see the rear thrust was completely off. It got dialed in, and now it drives like a whole new car!

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

(https://i.imgur.com/XdSgh6N.jpg)

I did some driving and test hits and it sure does hook up much better. Still need to roll on the throttle in second, but third is fairly solid now. I ran into an issue with my fuel gauge reading funky. It would bounce to full every now and then, and after some troubleshooting I was able to narrow it down to the sending unit in the tank. I bought a replacement float and resister unit and swapped it in

(https://i.imgur.com/2Efc656.jpg?1)

It did the trick.

I brought the car out to its first car show as well, parked next to a buddy in his MKIV Supra. The car got a lot of attention. Although the FD gets dwarfed by the Supra ha, it's small size really shows.

All in all it was a successful weekend and it felt great driving to and from the car show, car is getting so close to getting all the minor bugs worked out. Engine now has about 200 miles on it, and is on its second oil change of break in oil.

Hey Esser!  First off, thanks for the awesome pics in your build thread!  Has really helped me out with my build.  I have a question about the Borla XR-1 you have in the midpipe; did you use the 12" long muffler??  from the pics it looks like the 16" one may have been mocked up but then you went with the 12 " for extra clearance.  I am going to go with the same set-up up front and a Trust rear section that I can take off when I take the car to the track.

You are correct, I mocked up with a 16" thinking it would fit, but it didn't leave enough clearance for the rear section to bend.

I ended up going with the 12". It is still really quiet at idle and low throttle, exactly what I wanted.

Did some interior updates, I was able to score a really nice OE Nardi steering wheel with the red stitching from Japan. It is a hair smaller than the stock FD wheel, which helps give a bit more leg room. The wheel feels super nice in my hands and flows well with the rest of the interior.

Finally had time to do some more driving, I just got back from completing One Lap of America with Toyota (in a Prius lol). My LS3 engine currently has 700 miles on it, and is on the third oil change. I have been taking special care to break in this crate engine:

Initial oil used wen I fired it up was the BR30 Gibbs break in oil
First oil change was at 100 miles using a second change of the break in oil
Second oil change at 300 miles using conventional valvoline oil
Next oil change will be at 1,000 miles and switching over to full synthetic

I did do some break in drives varying the load and rpm, but definitely did not go easy on it. Based upon some research iv'e done, it's best to get the engine up to operating temp and then try to load up the rings quickly to help them seat.

This last oil change I did a full weekend of auto-x, and it was a blast. This was the first outing for the FD, and I was able to place in the top 5 for the weekend. This was even on street tires (200tw RE71), while three others in the top 5 were on slicks. I was super happy with how the car performed.

I picked up a set of RPF1's for track and auto-x duty. They saved me 8 lbs a corner over the XXR's that were on it, you can really feel the weight difference in the car

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

The first morning on Saturday was a hard rain, but quickly cleared up and the rest of the day was dry.

(https://i.imgur.com/8oXaykx.jpg)

I went out and did some shake down runs first thing, the tires grip extremely well for being a tiny 255 square setup. I am able to dead hook 2nd gear which was not possible previously. The tein suspension did surprisingly well. With some tweaks to the shocks it was handling predictably.

(https://i.imgur.com/HfUpMlj.jpg)
(https://i.imgur.com/w3I2Xav.jpg)

The second day there was a lot more competition, and the weather was a bit hotter than the previous. On my last run the RE71's did start to get a little greasy and spin a bit. These tires definitely need to be cooled down between runs. Despite being a small auto-x track I was able to hit 70mph (top of second).

(https://i.imgur.com/wipW2br.jpg)

I was super impressed with the car's practicality so far, I drove to the event (1.5 hours away) and honestly was not sure how it would do being the first long drive I have taken in the car since completing the build. It rained on the way there and on the way home, but the car made the journey no problem. Ride comfort on the road is not too bad either, and exhaust does not drone. My passenger could have slept if he wanted to lol.

Next auto-x is on the schedule! and hopefully going to try and get some track days at NCM scheduled as well.

RPF1 master race. I have wanted different wheels for a long time now but the weight and practicality of a 255 square setup on 17x9 is impossible to beat. I think 255ís are a pretty magical size for an FD.

Yes the square 255 setup is great. and price is right on the rpf1's. Bang for buck is there, although i've been eyeballing a 285 square setup after my first event now. It still had trouble hooking second coming out of turns. I'll finish the season with these 255 re71's as going to an 18 inch setup is quite pricey.

I have not been impressed with the RE71R whatsoever.

Put an NT01 or R888 on it and don't look back.

I'm actually considering trying a Maxxis RC1 next, but don't have any experience so I can't recommend them.  I heard really high praise from people I trust though.

I believe @largeorangefont is running or has run Maxxis RC1 and liked them.  He will probably comment.  R888's are okay. I have never run RE71R but have heard many mixed reviews. and have heard lots of good things about NT01.  I have also been happy with my Dunlop Start Specs but might give the NT01's a try for my next set.

Another 5 thumbs up for NT01 :)  Great tires, they are my street tires.  I have a race logic traction control that I shut off they hook so good.  275-40-10 R and 255-40-17 F LOF got me on them and I aside from rain they are perfect for the 7.   :drive:

The real trick is finding a tire that is 200tw rated. The RE71 is about the stickiest 200tw rated tire for auto-x. They do great for low heat runs. The NT01 or R888 would put me in a different class.

Didnít realize you were sticking in a class. The Bridgestone is probably your best bet then. I gained no streetability to speak of over r888ís but lost traction which is why Iím a little miffed.

Maxxis RC1s are really good. They drive a bit different, but are comparable to NT01s. The have NO tread, so I am hesitant to recommend them for street use like I would a NT01. If you get caught out in anything more than damp conditions,  you will just have to pull over and wait it out.

The BFG Rival S 1.5 is supposed to be THE 200 treadwear tire these days, and is available in 255/40/17. I have not run them or the Hankook RS4 that is also supposed to be really good too, however.

Mpbdy, I think I'm going through a similar phase as you did. I'm now looking for a set of 18x10 CCW's to run a 285 square setup lol.

That seems to be the most logical route at this time, and is known fitment. You sold yours right?
Title: Re: Esser's LS3 FD RX-7 R1
Post by: MPbdy on May 24, 2018, 10:54:20 AM
Yeah I sold the CCW's - real cheap too I think $1200.  They were over 10 years old and needed a complete refinish which would have cost more than I want to spend on brand new wheels lol.  One of the barrels were bent slightly and needed to be replaced.  Fitment was sexy as hell though...I do still want an 18x10+38 in the rear again.  18x10+50 fit the front well with rolled fenders.  I run a 12mm spacer in the rear.

I'm thinking I may actually do a staggered diameter on my car...18x10 in the rear with a 275/35/18 and keep the 17x9+45 in the front with a 255/40/17.  I am just going to put some kind of r-comp back on..if I ever track or autox my car it'll just be for fun.  The traction on the street is more beneficial for me. 
Title: Re: Esser's LS3 FD RX-7 R1
Post by: Esser on May 25, 2018, 04:05:14 PM
Staggered is not a bad idea. The front makes it tricky to do a square setup, and the +50 offset is so rare on wheels in a 10inch wide. Makes me want to get the +20mm fenders so I can open up wheel options, would love some volks in 18x10 +38 all around!

But the weight savings of the RPF1 17x9.5 with 255/40 is crazy. It was exactly 8lbs a corner lighter than the XXR's and you really can feel it.

Yokohama ad08r 255/35&295/30-18 here. Both almost exactly 25" tall. Pretty much the perfect staggered setup if that's what you are after. A 10" wheel in the front and 11" in the rear are best but I run both of mine on 18x10's.

I went with 18x9.5 +45 Advan RGIII.  15mm spacer in rear with a medium roll.  RE71 255's all around.  No experience with the LS3 yet though.  I figure I will try a 275/40 in the rear if I burn these off quickly.

I went to a car show this past week and they had a dyno competition there. I put the FD on the rollers and did a couple runs. With some small changes and a new ported intake manifold I was able to lay down some better number: 434hp and 440trq

It was enough to win a trophy for the highest HP NA V8 at the show!

Finally updates.

LS fest was in early September, and I had a ton of prep work I needed to do. One of the main points being a corner balance and an aggressive auto-x alignment. I was happy with my RE71r tires for now although wider on all 4 would have been desirable, just couldn't source CCW's in time. I took my car to a shop in Louisville, KY called The Winning Formula - they specialize in performance alignments. I told Aaron exactly what I was going to be doing at LS fest and what I expected out of the car. I chose to compete in the Grand Champion Event which consists of two different auto-x set ups, a drag race, and a road course type challenge. I figured this would be a great way to really test the all around performance of my setup.

I trailered my car to The Winning Formula, they have a ton of cool projects going on there. Here are some photos from the journey:

They got my car on the rack and got to work.

Here is what Aaron ended up with on the corner balance and alignment. It is a fairly aggressive setup, but a good compromise for all of the events I plan to participate in. He was impressed with the way the car drove, and I could immediately feel a difference once I took it for a spin. Aaron was able to catch some small issues with some joints that had loosened up over the break in period, so I'm thankful he took his time to look over my work. He also raised the rear of the car up 5mm to aid in traction.

I trailered the car back home and went over the rest of my drivetrain components, checking for other fasteners that loosened up any and snugged them all up. I changed oil again, washed the car, and deemed it ready for some abuse!!

Is the toe measurement inches or degrees?  Toe in front and rear?  I bet it handles way better getting everything evened out side to side, especially the toe!  How's the traction with that much rear camber?

In degrees, and yes slight toe in on both, it handles phenomenally. It's crazy how much more predictable it is.

Somehow, it hooks better than it did before with more camber. I think it's because he raised the rear so it squats a tad. I can dead hook second gear with the RE71r 255's so I am happy. Although I still want more tire back there.

All loaded up and ready to go down to Bowling Green at the NCM track! Super excited to compete with other LS's and get some nice advice from other drivers. I'm a bit in the minority with a import car there, but that's okay I like the uniqueness of it all.

I drove down with a buddy that has an LS swapped rx8 that was also competing:
(https://i.imgur.com/SXOdocT.jpg)

LS fest was packed, there were over 200 competitors for the Auto-x. they split them up between two groups (one at each track) to let everyone get their runs in. On the second day we switched locations.

saw a fellow norotors friend "Kevin Doe" there, with his much more purpose built FD! It was nice being able to talk to someone with similar setups!

Some on course photos below. Yes this is me loosing traction and hitting a cone lol.

After all the day's festivities I was able to relax while the car show happened. I got a lot of questions and compliments on the swap:
(https://i.imgur.com/pLyeFCB.jpg)

The first night was the drag race. I knew I wanted to see what the car would do, but I was also afraid to break my stock Mazda rear diff and not be able to compete in the next day's races. So I left off idle and completely fugged the 60 foot, but was still satisfied with my time and trap speed despite the slow take off.
In line waiting to make a pass:
(https://i.imgur.com/cTQ77zx.jpg)

And the slip...
(https://i.imgur.com/U6NFoke.jpg)

My goal is to come back when not on street tires and make a better pass! the event also made it apparent how much the 4.10 rear gear was holding me back. I was having to shift into 5th to cross the 1/4 mile which was killing time and trap speed. The traction is also hard to control with the 4.10 on the track, some courses I had to shift as well. A gear change is in the near future.

All in all, I ended up placing in the top 15% of the entire group based upon the Auto-x times. I was super happy with this, as the cars in front of me were purpose built cars dedicated to auto-x. And I was on the smallest tires at the event ha! It's some good motivation to get a new tire setup and come back next year.

Nice!  I am continuously impressed with how well the FD chassis handles this much power.  They have better traction than any corvette I've been in or driven.  I had a C5Z for a lot of years and they just don't plant the power the same, and are nowhere near as predictable to drive at the limit.  Corvettes bite you hard.

I had my FD aligned with 0 toe front and rear and I'm excited to try a bit of toe in at the rear.  It has always felt knife edge in a straight line.  Handles like a dream though.

Awesome pictures!  Great to see you out enjoying the car.  Mine has been down for a bit can't wait to get it back and start hammering it again.  Cool to see Kevin out there also.  Norotors OG still out there killing it.  I figured he would have sold it by now.  Wish he still posted here.

I was able to pull a 1.76 sixty foot and run 11.18 at 127.21 on RE71R's and a 3.73 rear gear.  I was able to ride the clutch out and keep the tires stuck through first.  When I had the stock 4.10 diff I raised the limiter and ran through the traps at 7200+ at 129.85 mph.  My poor baby cam stock headed stroker had its tongue hanging out lol.  I'm actually rebuilding my car with a 3.90 gear right now to get ready for another engine combo.  In some ways I miss the 4.10 gears and MN12 ratio T56 for playing around on the street...I'm down about 20% wheel torque in the first three gears.  It was a lot of excitement for staying under 100 mph lol.

Agreed, the C5 just seems sloppy compared to the FD handling. The 3.90 gear is ideal for me to go through the traps in 4th at 7k rpm with 26's.

For street tires, the RE71r's cant really be beat, they require no heat up period. Just grip the moment you're engines warmed up lol.

What new engine combo are you going with??

Yes the R888 does hook better in a straight line, although you can't get R888 anymore, and the new R888R has the stiffer sidewall so it doesnt hook quite as well in a straight line. The soft sidewall gave it drag radial like behavior.

So I made the first road trip in the FD, a trip to Tail of the Dragon. It was my dream to take this car down there at some point, and so glad I did. It was over 1,000 miles round trip, and the car never had a single hiccup. I was able to go with some buddies from work: 2JZGTE IS300, C6Z, and STI swapped RS. All of us were in the same realm of speed, I drove down on my auto-x setup and ripped on the dragon, it was a blast. Pics below.

And Also got to do some drags with the C6Z, and we were neck and neck - a drivers race for sure. This has lead me to the decision to do the next logical step... a simple cam swap for some more cheap power.

LS Fest was awesome. The entry fee was only $130 and that gets you into essentially all events: 4 different auto-x's, a small track event at NCM, the drag strip, car show, and you can dyno your car if you wish. Will definitely be going back! The events were well organized as well, I hope that next year is the same. Weather held up great until Sunday afternoon as well.

Put the FD back up and jack stands and I tore everything back apart so I could get the cam ready to go in. I worked with Cam Motion and EPS to get a cam designed that would meet my needs (road course, auto-x). We agreed on a grind that would hold the lobes stable at high RPM and still make some pretty good power up top. 228/240 sized cam.

List of items I bought to install:

Camshaft
Katech C5R timing chain
Melling HP oil pump
BTR valve springs
Titanium retainers and hardened push rods
Ported throttle body
LS2 style tensioner (ditched the LS3 style)

BTR platinum springs and Ti retainers in!
(https://i.imgur.com/DSiAbaC.jpg)

The I went on to the cam and oil pump. The Cam motion ground cam was made of their 8620 alloy, which has a bronze like finish to it, and it was nicely polished up! It's an impressive looking piece of machined metal!
(https://i.imgur.com/EUm4atu.jpg)
(https://i.imgur.com/3XdBrzG.jpg)

I primed the engine again, flushed a bunch of oil through it because im super anal about keeping this engine clean, and put on a fresh filter. I overlooked all of my connections for a few minutes to make sure I didn't forget anything and fired it up. It started on the first go, and idled like a champ. I'm on a speed density tune, so it will need some attention at the tuner soon. I am hoping for about 50hp gain and some strong midrange power inceases. Although the cam is somewhat small for most LS3 cams it does have a pretty choppy idle, the volume of the exhaust has increased tremendously. Idle video here:

Took the car to get tuned, it picked up some really good power everywhere in the rpm range! super happy with the cam choice.
Here is the before and after on the cam swap (this was done a dyno dynamics which reads a little differently than typical dynojet numbers)

Definitely noticeable, it gained about 50hp/40 ft lbs across most the power band. And in the lightweight car it was a whole new animal. I went from hooking 2nd to spinning the top of third. I'm on the hunt for a new wheel setup now for some more meat.

Idle is a little more tamed, but still added some challenge to low speed driving esp with the aluminum flywheel combo im running.

I've been messing around with my cars tune at idle and other areas trying to get it to drive a bit smoother. I've made some progress and have "smoothen" the gear transitions and increased drivability. I'm very curious about your tune settings and was wondering if you happen to have access to it? If you do, would you consider posting it online so I can take a look at it and compare it to mine? Since I've got the idle down to 850 I'm actually wondering if I can go even lower to 800. I found 50rpm makes a huge difference when it comes engine noise and exhaust noise at idle. If I have time I may even try to push down lower. I believe stock ls3 idle is somewhere in the 600s. I'll be a happy camper if i can get away with with a solid idle in the 700s with minimal spark correction. That would really quiet the car down, burn less gas, and produce less heat at idle.

BTW did you ever find a set of ccw classics? I recall seeing you looking for some in the past but don't remember if acquired them?

The Cam motion lobes are known for being pretty soft and quiet. My C5 vette has a cam with XER lobes and this cam motion cam way LESS noisy. I can't hear any valvetrain noise at all unless you get your ear right next to the valve cover

My car is tuned on speed density, so unless you are running the same it wont be apples to apples. My tuner (James Short) spent about 4 hours tuning my car, and literally one of those hours was just on the idle tuning to get it right. It's very difficult to kill the engine, which was surprising for cam + alum flywheel. I figured I would need to give it gas everywhere to get going, but I don't have to at all. I'm extremely happy with the tune. 

As far as idle tuning goes, I wouldnt fluctuate too far from where the engine is making peak vacuum. That should be a good reference to use, but if you're trying to reduce sound and gas consumption at idle then you may have to sacrifice some idle quality.

I am still on the hunt for used CCW classics. One of these days I may break down and buy new ones if a set doesnt show up soon! Really wanting to run 285 sqaured
Title: Re: Esser's LS3 FD RX-7 R1
Post by: sonicgroove on December 13, 2018, 04:12:21 PM
When I first got the car the idle was approx 1k and would hang upon deceleration. It also had a fairly notable chop level. The high idle made driving easy but the transitions between gearing was very rough because the car wanted to take off. I've since fixed it and actually found the lower the idle the smoother light daily driving becomes. I went from 1000 to 950 to 900 to 850. 850 was my original target but now I'm thinking I'd like to be at 800 or even 750, if the car will allow it. The chop factor has also decreased which apparently helped with engine vibration at lower speeds and reduced vibration noise that I've been trying to diagnose. I haven't had any problems at 850 and feel like 750 may be the sweet spot. I'm just not sure how much vacuum I'll be pulling at that range but if she holds steady I'll be one happy camper. I'm using an e40 ecm so it doesn't have as many options for idle tuning as an ls1b or e38 ecu but the restrictions of the e40 ecm makes tuning simpler due to the fact that there is only so much I can do. Btw this is on a stroked ls3, milled l92 heads running a TSP Cam 229/236, .624í/.615í, 114 LSA 3 bolt cam.

Whats your idle at operating temp with those 228/240?

I've feel like a used set of ccw classics aren't going to show up no matter how much I beg Santa so I may end up purchasing a new set myself. I'm looking to get some before the year ends hoping for some sort of holiday discount. I'm also leaning towards a square setup but don't really like the idea of running spacers and 10.5" is a bit more appealing than 10", at least thats what she said.

My idle is right at 850 hot. It seems to do fine, and it doesnt even shake the car at all, like most cams seem to do. It shook the car tremendously before the tune at about the same rpm.

I am about to pull the trigger on CCW's now that you got me thinking about it. 18x10.5 +50 squared. Wish they still offered the race faces, I'll have to settle for the basic ones it looks like. I agree on 10.5 being a better option, it will stretch the 285 correctly and allow 295 if I feel like i ever need it. RE71R 285/30/18 is ideal for my goals

Post by: sonicgroove on December 13, 2018, 06:36:57 PM
I heard 10.5 in the fronts on a rolled stock fender is super tight requiring alot of camber and, for some people, rub inside at full lock. I was also concerned with increased tramlining with daily driving. Its one of the reasons I'm stuck at deciding between 18x10 +50 front/18x10.5 +50 rear or 18x10 +50 square with a 10mm to 15mm rear spacer, or as you mentioned 18x10.5 +50 square. If you don't have troubles with the 10.5 square setup I may end up running the same. Hope you don't mind being the guinea pig.  :) I'd be interested in your thoughts on the matter and look forward to seeing those wheels on your car. Its going to look so ridiculously awesome sauce all over deep fried butter sticks covered with bacon bits.

I'm surprised the lobes are that different. Mine can be heard at all times..
Iwill tell you that a 255 AD08R has a hair (5-10mm not the 30mm difference) more stretch than a 285 sumitomo. Some tires just run wide. Look at section width rather than listed ratio width.
Even a 10.5+50 will want a 5-10mm spacer in the rear to get close to flush with OEM spec camber. Said 10.5+50 will rub the lower control arm in the front and probably stick out from the fender.
That said, if square is the goal, I'd run 10+50 and a spacer in the back with arp studs. This is what I run now. Otherwise staggered, I'd run 10+50 front and 11+45 to +40 rear.

Considering my wheels are square but my tires are 255/35 & 295/30 that's a pretty easy answer. Ha

I used to have a 285 all round but tramlining was just too much.
Title: Re: Esser's LS3 FD RX-7 R1
Post by: Esser on December 14, 2018, 02:18:37 PM
I just crunched some numbers and took some measurements.

I'm running -2.4 degrees of camber in front, which has been giving me some great tire wear in front during auto-x so I have no plans to change it. That opens up a lot of space for some more tire. I ordered some CCW classics in 18x10.5 +50. And by my calculations I should run a 8mm spacer in the rear (1.8 ish rear camber right now). They told me 4-8 weeks until they arrive. Worst case scenario I get a new front barrel to make them 18x10 wide, but I think the 10.5 is going to work just fine, and better utilize the 285 tire.

On another note, new diff. I believe MPbdy put this together years ago and it somehow got into my hands. It's a 3.90 gear ratio which will be ideal for me on the 1/4 mile. Previously I was crossing the 1/4 mile in 5th, so the new gears should wind out 4th all the way. Also instead of the torsen it's got the Turbo 2 clutch type diff known for its strength.

Oh yeah also got these a while back, needing to get them mounted for the strip. I figured I should make some attempts for a better slip at the last test n tune at Beech Bend this year. Curious what the car can do.

If itís my diff it has the 4.10 unless someone swapped it :o I did put in the turbo 2 clutch pack though. Loved that diff! My 8.8 experiences havenít been quite as good.

Looking very nice. Can't wait for the ccws to arrive. What color scheme did you go with?

What you hoping to trap on the 1/4?

I ordered polished lips with gunmetal centers.

The hoosiers are looking fat on there!

Those hoosiers paired with that exhaust tone, if I was an innocent bystander sitting at the bench in the quarter mile, I'd be like that shit is going to run 9s or better! Shit looks tough.

Polished lip with gunmetal matte face was definitely what I originally wanted but lately I've been considering other alternatives that may match a white vehicle a bit better. Who knows though, your pictures may sway me back to that combo. I'm really excited to see your car with those wheels. Please be a picture whore when they come in.  :)

What 8.8 issues have you had?

The Samberg Cobra 8.8 mount is made from pot metal.  I broke it twice.  Second time the diff and driveshaft came up and hit my floor, ruined my $700 driveshaft and when the welds failed the mount broke loose and deformed the mounting points on the floor used by the Samberg brace.  Luckily the Ronin 8.8 mount does not use the epoxied on nutserts as a mounting location.

I now am back on the road with the Ronin setup, but was a fairly massive expense that I wasn't really thrilled to do.

Ah so not 8.8 issues but rather samberg cradle issues. I had heard about those issues. Glad I went straight to the Ronin 8.8 setup.

Do you have any pictures of what failed?
I have the Samberg Cobra setup.  It has a lot of clunking, and a bit of gear whine, but nothing has broken yet.

On my third pass I ran a ten second 1/4 mile. Super stoked with how everything performed! I'm glad I got the pass in before the new years so I can go back to focusing on the road course setup.

Wooohooo!  :D That must of been fun. Numbers are consistent with your power output. You may even hit 10.7 or better if you can get that 60 down. What were you launching at? Either way that is awesome. Congrats on hitting 10s.

Those slicks and skinnies worked like a charm!  Is that a 1.65 sixty?  The slip is a little blurry.  On a dynojet I'd put you around 480whp.  Nicely done!

My best on street tires driving off the line is a 1.76 sixty and 11.19 and I'm at 465/450.

That's fast, congrats!  I was trapping 127 with 475 RWHP.  My car is kinda a pig though.... needs to go on a diet. 

I should rent those slicks from you to see if i can get low 11's...

Car looks great man. Mind sharing the specs on your Weld/Hoosier setup? Did you have to grind down brake calipers to get them to fit? I know many have had to do that due to clearance issues. If this is in the thread already, my bad.

Thanks, I didnt have to grind any brake calipers, just had to use a socket cap screw on the trailing arm.

Specs are:
15x9.5 6.5bs"
15x4.5 2.5bs" (with 8mm spacer)

This is ideal fitment for rolled fenders

Tires are 25x5 fronts and 26x11.5 Hoosier QTP's. They grip amazingly on the strip, I would bog from a 5k clutch dump

New season, new wheels. My CCW wheels arrived this week, along with my new tires. Specs are:

18x10.5 +50
285/30/18 RE71R

Can't wait to get these mounted up, they look great just sitting here!
Going to have to do a lot more front fender rolling to fit these up front.

Be careful at full lock. Those specs will probably rub on the front LCA at full lock. Mine do occasionally at .5" narrower.

Have been installing some new parts so far:

99 Spec front bumper
Shine auto 99 spec cf lip
Shine Feed style side skirts cf
and of course the new wheels and tires

I had to do a lot of fender rolling in the front to clear the 18x10.5 with the 285 bridgestones. Pulled them a little too. But they clear!

The real photo shoot is coming soon!!! photos downloading now

Oh god... be careful your thread doesn't get flagged for posting up car p0rn... my car just dripped oil everywhere  :laugh: Very very tasteful mods.

Can we get more side profile pictures?
How is it at full lock?
How much camber did you need to get them tucked in?

At 95% of full lock it rubs, havent checked where tho. not too concerned about that.

I'm running -2.4 degrees front camber

Post by: wickedrx7 on March 20, 2019, 03:14:10 PM
Thatís too much camber for the track imo. I was running that high originally and completely wore the inside of my tire. Temp test confirmed it. If I recall, I went down to 1.5 on the front. I can check when I get home from a work trip if you would like. It evened out my tire temps and wear dramatically.

Post by: sonicgroove on March 21, 2019, 03:31:10 AM
BTW do you plan to change out the rear to anything or planning to keep it the same? I'm partial to the 99 spec wing and concept 7 duck tail spoiler. If your taste continues to remain consistent with mine perhaps you may agree?

My car is about 90% auto-x, and I kept adding camber until the wear marks on the sides of the tire were within reason. I'm actually needing to add a slight bit more :shocked: Just chalk the tires and it will tell all!

My only plan is to eventually delete the R1 wing. I am either thinking a small duck bill like the shine one, or no wing at all. I like the clean look!

Post by: sonicgroove on March 21, 2019, 01:55:46 PM
I personally think the concept 7 ducktail is more appealing than the shine. The flare is more aggressive and curvature doesn't come  down around the taillights as much. Here are some pictures if you haven't seen it. LMK what ya think.
