Sorry to quote myself, but it is a nice segue.
Do you all suppose the Hayabusa V8s were cheap to develop? After all, its just two Hayabusa engines stuck together, right? Do yourself a favor and google the development process for these. It was VERY challenging and expensive.

Levi, wou are suggeting two N13B16 engines be mated just as with my example above. Not cheap.

The 1.6l I4 making up to 220 PS, as a V8 it would make 440 PS, all this from a light 3.2l V8.

N18B16 makes 220 hp, but that is for FWD applications. N13B16 is a completely different top end and induction system. Could it make 220hp? Probably, but BMW obviously developed the N20B20 for a reason. More efficient for 200hp+ application.
It would nevertheless be neat. But how compact? You may end up with something 95% of an N63 in size.
