S4 with S5 motor & box!
I agree with most things here (especially those farking balljoints!)
We have the normal belts here on all models, and never bother playing with factory ECU's
But don't forget S5 engine has higher compression, lighter flywheel and rotors, better exhaust manifold & split pulse turbo with much larger wastegate area. None of this really matters if you are upgrading tho
You boys S4 have noticed the resonance that goes thru the gearbox @3500 in 4th at full throttle? S5 gearbox has a harmonic balancer on the output shaft to eliminate that. We use S5 boxes with steel flywheels that take S4 clutches, cos the range of performance clutches in the smaller size is far greater!
