work in progress

[skunk]

I just bought a 87 supra turbo, giving the known head gasket problems I decided to replace it. When I removed the turbo my nightmare came true, the turbo has a small crack, along with hairline cracks around the internal wastgate exhaust port (common problem). My question is can I change the single wastegate exhaust housing with a little bit later model dual wastegate exhaust housing also changing manifold and down pipe to fit six bolt pattern. Any ideas you all have would be greatly appreciated, thanks.
