Ok so i know im repeating a very covered topic but my question is, what combo/is the normal 2.8 cranks swap good for forced induction? When i say the normal 2.8 crank i mean the combination of... m50 crank, crank spacer, eta rods, and 325i pistons. I saw on a thread that i have since lost that this combo will yield a 9.7.1cr. What i want to know is, is this the best combo i can get for a turbo build? 9.7.1 seems a little high compression. If there a setup that will yield a lower compression ratio?
Any input is appreciated unless you want to say i should m50 swap.
The car already is getting a ported and polished head with bimmerheads dual pattern turbo cam, upgraded valve springs and HD rockers.
