I need an 02 housing quick.  I own a 1990 sunbird GT turbo and I'm putting a TGP turbo on it.  My o2 housing should've fit, but I think that I have some strange non original turbo.  So if someone has a thrashed stock turbo and just wants to sell the o2 housing let me know.

what's not fitting that you are hoping to fix with a different housing?

My o2 housing does not bolt onto the turbo, not the exhaust to the housing.  I'll have a different down pipe built any way.  The cast iron turn down.  The piece that has the hole that the o2 screws into, wait I forgot the TGP turbo the o2 hole is in in the topside of the turbo... ok the cast piece that covers the waste gate flap and the turbine blade.... I don't know how else to explain it.  I've had a couple other places that I post tell me how to clock it... I have that one covered also.  

I hope that helps you guys understand me

I saw on another posting turbo discharge flange... I think that is refering to the part I need...
