how about an 2.2l i4 with 9k redline + turbo for the new gen m3 that produce 480hp? haha
for example, the s2000 just a 2.2l i4 that produce 240hp. So this must be doable. This will in turn reduce weight significantly too because the s2000 i4 weight next to nothing.
I this would make more sense for m car than to fit a low reving engine with turbo. Then it would be the same as the 335i.
