I have a GT17 that I picked up awhile ago. I can't find out what flange it uses. It's shaped like a T3 flange, but smaller. (Assuming it might be a T2.)

It needs a 3 bolt exhaust flange, but I don't know where to find one.

Any help as to what the flanges are or where I could look up the information would be greatly appreciated.

Nobody has any ideas?

A lot of OEM GT turbos use their own flange. You'd have to find out what car it comes from and get a flange for that car, or just take a plate of steel and drill the holes. The garrett site only lists the gt15 and gt20 flange sizes, and are both 4-bolt.

I think that's what I'm going to end up doing for the exhaust flange.

For the manifold/turbo mating part I'm either going to drill out the holes on my manifold that's a T3 (holes are just barely off) or I'm just going to go buy a T3 flange & weld it to the turbo.

Ever find the correct exhaust flange for this?
Inlet is a t25, but I need an exhaust flange for the turbine exit.
