M60 vs Boosted M42

[Massimo]

I did not vote both are awesome options the v8 swap would be more reliable but a boosted m42 is a boosted m42

Looking to swap my 318i in a few months. The reason I want to narrow it down now is so that I can start collecting parts. I am trying to get between 230-300 hp. The car is not my daily so it could be down for weeks if need be. I don't mind losing power steering and ac either. What's the best bang for my buck.
