There is always debate on what will work with the s4 and s5 turbo swaps. So what parts are different between the s4 and s5 turbo cars? Let keep it simple and only talk about engine components.

wiring harness
ecu
rotors
front cover


add to the list and if you know what makes them different add that aswell
