m20b25 turbo build

[gd01]

I have a m20b25 which I am rebuilding and will be swapping into my 86 e30. The engine will be turbo'd later.

The engine is currently being rebuilt with new rings, race bearings, rod bearings, arp headstuds, and a full head rebuild.

The turbos which I will be putting in are from the n54 twin turbo.

My question is, which head gasket should I use? Should I get a new one directly from BMW? or should I be getting a MLS one? I will be running approx 10 psi boost.

Also, I am planning on changing my clutch to a stage 1 aftermarket clutch.

I will also be using the flywheel from the 2.5i which is lightweight, but I also have the one from the ETA which is heavier. Will the ETA flywheel be better for turbo purposes?

Thanks guys!

Use a Cometic MLS, a standard one may well work fine short term but it wont last and you'll be regretting it when you need to pull the head off .

Lighter flywheel the better , i wouldn't recommend a paddle clutch, stage 1 or 2+ is best i think.

post some pictures up
