so im wondering how much harder itll be to put an s5 motor into an s4 shell, tII ofcourse. does everything bolt up no problems basically? does the wiring harness go in the same as stock basically? thanks everyone and sry for all the posts lately

If you have to ask S5 into S4 it would be to hard for you. No the harnes will not fit.



Stay S4

i read a piece on rotary resurection that said u had to change front covers and blah blah blah, but that was using an s4 ecu and wiring harness. basically im wonderin if the electrical stuff from the s4 and s5 are interchangeable, like headlight plugs and all that

rowtareh

it's not interchangeable. you have to figure in that things are different on the s5 to the s4.



stay s4 or go aftermarket ecu.

well the good news is i found an s4 motor with wiring harness (what i needed) so i dont need to go s5, thats kinda what i figured tho
