Hi guys
I currently have an m62 swap in my 318is but i recently decided to swap back an m42 in it

I am looking at building a serious turbo set-up with a friend of mine of is a pro welder and can build many parts for me and his m42

I have taken a look at many plenum design but haveńt found any info on dimensions
, specs anywhere.
Is there a post or a member that is willing to share info?
I am planning on build a serious engine possibly with a stroker and cutom made exhaust manifold and plenum
Any info would be appreciated as i'd rather ather info before starting
Thanks a lot
