I bought a T3 4-bolt flange thats supposed to work for T3's T3/T4 and GT turbos.

It doesn't fit! Here's some pictures.






Any suggestions?

My turbocharger is a Garrett T3/T4 hybrid .60trim with .63 A/R

I think I bought a GT exhaust flange.

Are regular T3/T4 hybrid ones different?

well why not open up the holes a lil more. it might make it weak and crack though, not sure, just get another one. make sure when u buy it, you measure the proper diameter on the turbo, and ask for that.

I'll take more measurements mang.

Problem solved, I bought non-GT exhaust flange.

New problem though - my oil outlet flange is a 1/2" NPT, but my 1/2" NPT to 1/2" hose barb fitting won't thread in!.

Argh!

Problem solved, bought brand new oil inlet/outlet adapters.

Turbocharging sucks.

ohhhh but its soooo sweet when you get it right.
