Turbo M20B25

Post by bugboyaidan »

Hello all, I have a e28 that I'm swapping an m20b25 into from an 88 325is. I'm curious as to what supporting mods I would need to run around 7psi or less. I have seen some running completely stock systems with only a RRFPR but I'm wondering what sort of a budget I should have for a simple setup and also if anyone has parts they can sell me?

Completely stock with an RRFPR is a great way to go for that boost level. Stock injectors, stock AFM, stock fuel pump. The stock clutch will hold it without issue unless it's on the way out.

Your budget depends on the quality of the components you want to use. A reasonably nice home made setup should run about 3000.
