It looks like you might need to resurface your gasket surfaces. If the shop does a good enough job you may not even need a gasket. See if you can find a shop that will surface grind both surfaces of the manifold and the turbo inlet to a finish of 16 (microns differential height). I think that will be sufficient to run without gaskets at the (relatively) low pressure.

If you can't find a shop to do that then use a metal straight edge diagonally across each flange. Use a feeler gauge to see how much difference in height there is between the high/low points of the flange. If it's more than about .015 then it needs surfacing so your can keep gaskets.

I wonder if you could make your own out of think copper sheet?

I don't use a gasket on my turbo -> manifold flange and as far as I know there is no leak.

the manifold/turbo gasket for a 300zx twin turbo vr4 should work, but you should try no gasket and tightening the sucker down better....looks like you had two leaks on the head as well.

don't run a gasket between the manifold and the turbo. Had no problems with my Galant VR-4 that way.

Had lots off problems with gaskets... Finally a saab gasket (single layer) fixed it..
Be sure all surfaces are flat ... (if resurfaced run without gasket!!)

I could do with a new Turbo -> DP gasket on mine really.

Anybody got the definitive part code/source for one that would work on the Greddy TD04??
