You don't have to change the transmission if you have the crossmember for the engine.
The big thing is the wiring.If you intend on staying with the s5 wiring then you have to change stuff.
If you alter the engine components on the s5 to allow it to be an S4 engine(like the front cover with the mechanical Omp instead of the s5 electric OMP), then you can make the engine plug and play as an s4.You would use the s4 harness and the S4 Ecu,boost sensor,AFM,s4 injectors.
Search the Archives and the Sec Gen specific sections..It's there,it has "been done" just a few times less than Kim Kardashian!!
So LOTS!
