Hi all, My 1996 Subaru Legacy GT had been through a crash but no damage to the Engine at all. So i decided to buy a 1998 legacy GTB body, so i could put my engine into that. 


I have got that done and now im down to the last couplie parts which is getting the timing done, and getting this ECU put in and hoping for the best that its gonna work.


So my question is do i put the 1996 ECU chip in ? or the 1998 ECu chip in? because im getting it done as a home job. & unfortunatley the people doing it aint quite sure themselves.


I hope someone can help me here , and also which is for which i have a chip that is black stickered with 87 on it and i dont know which MOdel its from, and ive been looking on line for 98 ecu's and their saying the 4g one is for that so im stuck.


Also is it possible to do this? i have heard the car go before with the engine in but it didnt go for long, the coils and the ECU burnout, but its been soo long since ive looked at the car i have forgotten which one burnout.


Both the cars are manual and the engine is a standard twin turbo engine that you get lol, even like wiring and stuff would some1 be able to help me there to do i put the 98 wiring in or the 96 wiring in. 


Some 1 please help thanks :)

Cheerz :)

the ECU should stay with the car, not the engine.


so do not change the ECU.

keep the ECU that came with the 98 car.
