I know its for the first gen but it should be close, right? like I said I am trying to use the bare essentials, I have looked over the Haynes manual, its seems to be the same as the picture and I think that picture is great. my car is just a race car and runs ignition off a toggle switch, and the starter off a push button. help is greatly appreciated guys!
nice build.. but why are you going off of 12a wiring?

Because I'm trying to wire the basics since its a race car, but I can't find anything on wiring the 13b and it's pretty close.

A little update for you guys, I got her started, but she dos'nt hold an idle, so I guess its research on how to keep this thing idling. This is the first time its started in 2 years, and Im very excited! all the money ive put in her is finally paying off.

if anyone has any advise on how to get an idle, it would be greatly appreciated, it starts up but you have to stay on the gas to keep it to idle, but when I first started it yesterday, she started right up and idled on its own for about 20 sec before it died, reading my wideband my AF's were about 13.1-13.7 so if i just can keep it idleing ill finally have a running car.

That's a very lean idle. Some fully warmed up may be able to idle mid 13's, but for a "cold" engine, one that's just started up, that's very lean.

Add more fuel to the coolant map. In fact, add more to all the fuel maps as you are running smaller injectors. Cold rotaries do not like being lean.
I only breezed through your other thread... I hope everything is wired and setup properly. Otherwise, nothing is really going to help.

fuel pressure rises to around 30-40 psi while cranking but when I stop the pressure bleeds back down to zero.
