Engine/Transmission (1994 - 1998) turbo housing

Will soon be adding the 16cm. Any need to smooth the bore, and is port matching to gasket a good idea? Would also do the same to the ATS, if I do it to the housing.

Between the ATS exhaust manifold and the head is where port matching is needed the most.

Thanks. Guess I will worry about that at a later date when the manifold comes off for what ever reason.

I would do port matching on both sides of the ATS manifiold. You will see a big difference in size.
