I want to know where I could buy an external wastegate exhaust housing for a garrett gt25r turbo. I cannot just weld the internally wastegated stock one shut because I am using a top mounted manifold and the stock exhaust housing is to big.
The ONLY 4 bolt ( external WG type ) housings that would fit up to a T/GT 25/28 are sized to fit a T03 exhaust inlet port, come in .63 or .82 only and it’s designed to work with a 53mm 76 trim T28 impeller…
