I know its somewere in these forums already, but i spent 45min and still couldnt find it (of course i got sidetracked and went into other threads and such).

so what is the difference between the s4 and s5 turbo motors? well as far as the mechanical things. I know the OMP pumps are different, the thermostat housings are different, what else?

Thanks!
Jonathan
