Hi everybody.

If read quite a few posts about this topic (. The general method seems to be to take the s4 main core and use the other s5 components (like turbo, intake manifold, sensors...) to pretend that its still a s5 engine. I wanted to know if or why not it is possible, to take the complete s4 engine with its engine harness and ECU and put it in the s5 car?

thanks for any input,

Harry

 

Wiring to the ECU (from the other parts of the car) is completely different.
