Ok I've been searching and no dice. I was wondering what the I.D. of the 57 trim Garrett turbo 4-bolt turbine was?? I'm thinking 2.5 inches, anyone out there know or can measure for me. I shot PhoenixTurbo a PM a few days ago but got nothing back so any help would be great.

 

itrs liek 2.37 or so

 

Cool thanks for the answer

...umm I have that turbo. It's 2.5" I measured it because I wanted a 3" DP and was wondering why the outlet was only 2.5".

edit: Actually I think you're right because I measured 2.5" from bolt to bolt, so the actual diameter of the exhaust "hole" might be that 2.37
