I have a turbo that I thought was a Q trim but just wanted me make sure by measuring a few things. At the base of the compressor wheel is 3.401” in diameter and the top fins are 2.611” in diameter. I'm counting 8 big fins and 8 small ones. I was told it was a T67-1. A housing that used to be on it is an undivided .96 AR exhaust housing and it is 3.163" in diameter for where the fins fit in. I'm just looking for a divided 1.0 AR exhaust housing for this turbo and people keep telling me it’s going to be hard to find one for a Q trim turbo so I wanted to see if that’s what it really was. If I need to measure the exhaust side fins I should be able to do that later or pics if that would help.

 

If you are looking for an exhaust housing then you have to measure the exhaust wheel, not the compressor wheel , I THINK that makes sense! and all manner of housings are available if you go to the right people.
