Justin I would love to test fit your headers! I am using the Sikky swap kit, so it would be another option. If they fit, I'll buy them!

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


Here's the shroud and fan fitted (pretty tight)


New fan plug


And I used the fittings and butchered rad cap to make an over-engineered bleed tank

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.

Looks cool, but that's big bucks (equivalent to $445 here).

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 wouldn’t 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


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.
