1993 FD project
 

so i purchased an FD off of craigslist about 2 years ago per impulse buy (DREAM CAR!!).
It sat for about 2 years while I've been getting my shit straight financially.
only to find out it was previously owned by a member here

these are the mods done by the original owner
i have found the car has no o2 sensor, the turbo seals and bearings are shot. the fuel system is a hackjob, the cooling system is a hack job, and the wiring harness is basically 2 wiring harness butchered together(not blaming him because another owner bought it before it got to me)

so far, I have ordered these parts to replace all known needed, and found to be defective parts:

-Borg warner S362 SXE 76mm turbine with 4.21 marmon flange .88ar open t4 housing
-cx racing lower intake manifold with single 4/6 injector fuel rail.
-ry wire engine harness
-basically all engine sensors, including wanna speed IAT, GM 3bar map. and innovate MTX-L O2 sensor, and koso NA dual EGT sensors.
-The electic fan mod already done has a horrible wiring job and is attached to a switch next to the shifter, I am installing a thermostatic switch to remove this.

This next weekend, i will be doing a compression test to make sure my apex seal are still ok.
I have gone through the forums a bit, and have a few questions i cannot figure out.
1)I am looking into A/I injection and would like to get some input of which water methanol kit i should run.
2)Does anyone know where i can get a base map for these injectors
3)Are there any experienced rotary tuners in the Seattle area.
4)Does anyone in the Seattle area know of a good exhaust shop who could weld in twin EGT bungs into my turbo manifold, and change the v-band on my down pipe and weld a marmon flange instead (I would prefer not to modify the turbo)
5) How to run 6 injectors with an Apexi PowerFC.
6) Does anyone know Which AN fitting for the borg warner, and where to source the parts. ( I'm sure i can find some online, but where would you guys recommend to source them)


Any and all advice would be appreciated, i want to get the engine running safe and strong, before i work on the rest of the car. I have a few wheel and suspension question for later but getting the car running reliably is the goal for now.

1. I don't like tuning with AI. I prefer to install it for additional safety and cooling. So if it fails or I run out of fluid the potential for toasting and engine isn't there. I have a Coolingmist pump with no complaints and mixed and matched other components. But it's a real simple system. Other brands are Aquamist, Snow Performance and Devil's Own and others.
2. Check your regional forum
5. Check the PFC sub-forum

With the replacement harness this may be of interest.... https://www.rx7club.com/3rd-generati...arness-879345/

BTW, your car had no O2 sensor probably because the O2 feedback on the PFC was turned off.

Advvice: Try not to do things backwards!

I see you ordered parts BEFORE a compression test.

Best of luck bud!

-could you enlighten me a little, appreciated

-Haha yeah i got a little gung ho, but i believe i have saved enough to not worry for the mean time, I'm ordering everything i find to be defective. and I'm fairy confident i don't need seals via the way it drove when i bought it, but i wanna be sure and have the whole engine set up properly before i tune it.

hope you dont need another rebuild!
