Swap over a few electronic parts, block a few other things off and you are good to go.

Swap the front cover, swap the OMP, swap the entire (from the throttle body back) intake and all the sensors.

S5 have lighter rotors I believe and run at higher compression. I'm sure there are a few other things too.

you need to rewire the dash harness for the s5 ecu. Not worth the effort
