Levi, When they build 1M they dont need to do anything on N55 engine, just chip little. Only bad thing is that intake noise is gone, but otherwise FI engines are lot better, It´s allso weigth less than S54 NA(N55 190kg, S54 ~210kg), maybe N55 aluminium-magnesium block makes differend.

I think next generation M3 F80 need forged engine parts if they wanted to taken +450hp, if I am rigth N55 engine doesn´t have forgen pistons, rods, crank etc?
