Im starting this thread to ask about the pros and cons of each engine. I was really interested in acquiring a 325i, but I have been reading a lot about the M42 engine and it is peaking my interest. I want to know what kind of potential the M42 has in relation to the S14. Also what kind of numbers might one see realistically from the M42?...Like can it be bored/stroked, ect.
Thanks in advance.
