With all this talk of the 335 coming to meet the challenge of the IS and G cars, I was wondering if some more 'tenured' BMW owners could fill me in.
The E46 M3 engine has somewhere in the region of 330HP. I believe the non US version has 345HP out of 3.2 litres.
Apart from the 250cc displacement, what are the key differences between that motor and that in the E90. Seems to me BMW could squeeze at least 300 out of the new motor. Cams? Redline? Compression Ratio?
Please educate me.
