LS RX8 Build - Project Norito

Update:

Fuel System: Complete
Parts
I put the fitting on the top hat but after the fact I should have put it on the other side as the fittings are too tall and I had to rotate it to get it to not hit the seat cover. Works fine but just a heads up.

I trimmed the return hose a bit to get it into the basket and it seems to like it as I was able to set 58 psi and it is stable.

This is pure overkill but I had this piece of AL sitting around and it worked to mount the FPR. You could probably hang the motor off this mount.

It's all back together and no leaks.

Alternator:
When the car first started up the alternator was working but after a few weeks it would do this weird thing where it would only work after I revved the car to 2k and then it was fine. Well a few weeks later it just stopped charging. I ordered and ebay special and it seems to work great. It has enough amps to run 3 of these cars so I should be fine.

I was able to make a heat shield to keep the radiator/motor/oil cooler heat away from the intake. I also got the IAT sensor close to the filter. Car seems happy and the Intake Air Temps are more accurate to what the engine is actually seeing now and not just heat soak.

Bonus:

Used some license plates to make a heatshield where the fuel and brake lines get closer to the exhaust.

How much did you end up paying for your driveshaft? Not sure if I want to go 8.8 off the bat or just get the swap working first with the rx8 diff, mainly due to timeframe. Cost of having to do a custom driveshaft twice will probably determine which route I go. Really appreciate how well you've documented this build so far.

Thanks for the reply, it was 458$ shipped and worked perfect. I will be uploading my wiring info soon too.
 
Wiring - it's fun!!

This seems more complicated than it is. One wire at a time and after 1 million hours it will all come together. If something seems odd or does not make sense it is possible I fixed it but forgot to update the spreadsheet. This wiring will pretty much get you pointed in the right direction for an swap but even more so for an LS swap. I have never done this before but I took my time and was able to work through it.

I have not double checked the wiring but the car is working only thing I have not totally got working is cruise control but maybe someday. It is the attached excel file.


This is the Deutsch connectors I used for the connections to the RX8 and here is the paper cheat sheet. I might clean this up at some point for people but it should all be here.
