Theres many N54 and N55's running about with nearly 400hp from just a remap so I'm sure 450 is easily available with just a change of internals,cams and turbo's etc - standard ///M tuning.

I'm nearly sure the current M5 engine (S63) has its roots in the standard N63 so I'd say the new M3 engine will be the same.

The S86 and S65 were oddballs in that they didnt have any commonality with the engines in the standard cars.
