I recently bought a new engine for my 91 rx7, it was originally N/a but i bought the turbo 2 engine and tranny for it, so i already put the engine and tranny in i just need to know how to hook up the old N/A wiring harness to the turbo engine, i have read recent forums and they say that it can be done, i just need the schamatics. plz help, any information will be usefull thank you

 

We did this on one of our 91 TII. Though it keep bogging out and wasn't burning all the fuel correctly because the air/fuel mixture wasn't reading correctly. I would suggest to try and find someone selling, juk yard, etc.. for a stock 91 TII engine harness. There not very hard to replace and worth it once your finished.

 

Wiring is somewhere on this thread....... https://www.rx7club.com/forum/showth...ht=photobucket

It really should not be a big problem on a S5 car, although I've never done a S5, only S4.

Look at it this way. The boost/pressrue sensor is in the same ole place. The afm is in the same ole place. Both engines have two primary and two secondary injectors. The Air temp sensor on the engine is basically in the same place. So what's the big deal? The routing of the secondary injector wires might be a little different. So?

Be SURE to use a turbo afm and boost sensor for the thing to work right.

And I predict Valentino Rossi will NOT be on the podium this day. If he is on the podium, then totally ignore the advice I just wrote.
