Turbo Exhaust Housing Question.

[Kanaric]

Around where I live used, and good quality, Garrett turbos are extremely common. 2860r/rs 2871r 2876r etc I can all find for like $400-$700 used by people for only like 1500miles or so as they upgraded to GT30 types.

My question is that I want to use stock manifold and exhaust fitment, what oem-style exhaust housing can fit these? If I can acquire a R33 or OP6 style housing would that work? I have a R32 GTS-T so i'm sure mine will not. Trying to keeps costs down and avoid having a housing machined.

I tried searching and you don't get reliable results on the topic i'm trying to find when searcing on these terms. Just housing sizing and things like that.
