S4 and S5 engine question
I have a chance to get a S5 Turbo motor and it is going to go into a S4 car. If I change the whole intake system to a S4 and premix would it be able to work? If not, what esle would I have to change. If someone could, could they list all that I would absolutely need to make the S5 motor work in a S4 car?
Thanks
Thanks

Leave the slightly better S5 intake manifold on, there's no need to change it. If you want to retain the S4 OMP then you'll need to swap the front covers and throttle bodies.

What I want is to us as much stuff from the S5 motor, but use the S4 wiring, ecu, etc.
So I need to:
Change throttle body
Change injectors to plug into S4 wiring harness
Premix
Am I missing anything else?

So its just the injector plugs that I would have to change on the wiring harness? What would I have to do about the knock control unit because it's different with the s4 and s5?

Now your saying that I can get a S5 complete engine and everything will match up except for the injectors and the omp. And what about the tps? Doesn't S5 have two and S4 only have one?
