I noticed today, as I'm getting my new turbo on, a mismatch between the manifold and the turbo.
Putting the steel gasket on the turbo shows there are 1 or 2 millimeters to grind off, almost all arond. So I did that. Together with the same work on the manifold it should be worthwile..
Anyone else done this?

Also on the std turbo there's an edge which stands out in the flow, so bad that it had 4-5 fatigue cracks along it..
