i see that both t3 and ihi turbos use the same 5 bolt exhaust flange,but my question is, can you use the wastgate from the ihi on a t3 or a t3/t04e hybrid?
As I recall, the elbows aren't the same on the IHI and T3. The bolt pattern is different and the elbow is different. So no, you can't use the IHI parts on a T3 or T3/T4.
