I am new the crowd here and in the middle of a motor swap on a high mileage FD (150K). While dissassembling the turbos I saw that the turbo exhaust housing with the wastegate was SEVERELY cracked around the wastegate to the point that there is no way the gate could seal, and some cracks around the area where the gasket seals between the exhaust manifold.

The original plan was to rebuild the stock twins and go non-sequential simply the nest of snakes under the intake....but looking at the full NS mods I still need that cracked housing/wastegate to be fully functional correct? Are there any cheap alternatives/replacements available, has anyone had success get the manifolds welded up and remachined?

Any help would be much appreciate... this is my first go around with the rotaries so I am anxious to get this bad boy on the road. I have used the search query quite extensively but have not been able to find anyones solution to the cracked exhaust housings.

Thanks,

Chris
