ok my next question is where can i find the wiring diagrams for the gsl and s5. or maybe someone who has in detail posted how to wire in the swap

 

Heres the wiring for the S4 T2 which is similar aside for the electronic OMP part.



Main harness wiring(S4 T2)

Look at the plug as it were pluged in the ECU.

The pins on the 87 harness are the same location however the colors might be different than the ones shown.

 

Wiring diagrams can be found here, along with most of the rotary FSMs, carb manual, etc..

Is the swap worth it, most definitely. Search and read through Steve 84gs post on the subject over at the RX7club forum. If irrc corectotly, there is a pinout thread in the 1st gen archives.

 

ok well thanks for all your help i think im going with the pfc. so i wont have to mess with that stupid afm. if you happen to come across any more info let me know cause im going to need all the help i can get.

 

This is a side project, right? It will take a considerable amount of time to finish.



Expect to spend no less than 4k for start up. More like 5-6 if done right with a few mods(ie PFC and tune).

 

it is a side project. but i have a few parts lying around i got the car for free and i can get the pfc for less than 800 and an engine and trans for 1000. and i have a 255 fuel pump and racingbeat has the oil pan and cross brace for 200, soim hoping to get it runnning for no more than 3000 but if i have to spend more oh well as long as its done right

 

Yeah it is the small stuff that gets you. If you are getting a PFC don't forget the tune. That will run you another 400-800 depending on the tuner.



There is also other small things that you might want to consider. Boost gauge, wideband, upgraded rad, FMIC... oh, and better tires.



There are some things that you are also forgetting like s5 harness, coils, TPS, FD igniter, FC fuse panel, new spark plug wires and other small little items. Trust me the list goes on and on.



Also it is reccomended that you upgrade the fuel lines as well. I do not know the diameter of the gsl lines but if you can get fuel lines off a gsl-se you will be set.



A great place to buy the pfc is jappartsspecialties. Heard nothing but good things from them. There is a shortage of FD pfc's right now so the wait is a little longer than usual. Price is 690+shipping through them with a commander.
