well im hoping to pick up an s5 roller in great shape but id be temporarily swapping my s4 motor and trans into it until i could afford a t2 swap for it .. but i was wondering is there anything mechanically different between s4 and s5 motors..i know theres a different intake manifold and that ill have to use my wiring harness but other than that will everything else be plug and play?

 

Yes.


No.


You need to either swap all the s4 electronics in the s5 car, or use the s5 sensors, intake, wiring, throttle body on the s4 engine.

 

as far as electronics what would need to be swapped .. sorry im a little retarted when it comes to motor swaps
