Hi,
Im an apprentice mechanic and decided to get a project car!
Ive got myself an e30.
Im putting a m50b25 into it and need some help.
Its all bolted in and need some help with the exhaust manifold.
Is this what I need? I did do some research and i need a m52 manifold?

Welcome mate.No they are not what you need.You need original m52 manifolds which look similar but need altering to fit.Coincidentally i have a pair available.Where are you located?
If you have any other queries search on here first as its been done loads of times.

This link is the definitive guide to installing M50/52 into E30,grab yourself a beer,notepad and pencil,get stuck in.
As you will have discovered,M50 sits at a slightly different angle to M20,fabricating the exhaust manifold is one of the more challenging bits of the conversion.

Malc, that link dates back to 2005, when Jimmy Saville was innocent.

I have a M50B25 engined E30 touring here still fitted with the cast iron exhaust manifold it came with, although slightly modified. This was built eight years ago, though, when M52 manifolds weren't as easy to come by as they are now.
