I feel like a idiot for asking this, but I've searched and haven't come up with a *real* answer



The facts:



- 88 AE with blown engine

- Order a 88 Jspec engine and receive a 89-91



So far, I know:



- Replace front cover\OMP\TB

- Replace injectors (or use resistors in the harness)



What I don't know:



- Do I need to change sensors? (like the BAC, etc)

- Anything else that I don't mention here



TIA

you need change everything except the engine block to S4. you will basically switch keg's everything is different!

 

well theres a couple of ways to do it.

#1. put s5 engine in car, adapt s4 harness to s5 motor, swap t bodies etc

#2. use all of you s4 stuff except the engine block and 89+ turbo (the exhaust side is way better)
