Hello fellow bimmerist !
I'am manufacturing turbomanifolds for BMW e30's. At the moment I have a nice model for m20 and m30 engines. Manifolds are tig-welded and parts are laser cut. Material is normal steel.
I make these manifold in Finland and if you think that someone in states (or elsewhere) would want one - I can find out about the postal costs.
Here's couple of old pictures of manifolds that I have made.. I'll post new ones if someone gets interested.
I can also manufacture m30 engine mounts for e30. Mounts fit to older m30 engine (not e34, e32). Two positions for engine. Laser cut parts - nice quality.
M20 turbomanifold 480$
M30 turbomanifold 540$
M30 engine mounts 180$
