I am extremely confused about this project i understand there is a FAQ page and i have scoured it looking for the answers but there is so much info going through my head i think im going to curl into the fetal position and suck my thumb...

My Car: 88 GXL Stock
Goal: Swap and S5TII into a S4 N/A. Trying to make around 325-350ish WHP.
MONEY IS NOT AN ISSUE. Just want answers

i know that the process is probably to freaken long to explain in a response, i would just like to know maybe the biggest things that i would have trouble with, the biggest differences in the the parts of the two or the POS-Cons in doing this swap....

 

the engine bolts right up, the tranny cross member is different, thats about it.

just go ahead and buy a stand alone ecu.
