okay so I bought it just to sell but now am curious inside the exhaust housing stamped .64 on the compressor it is .60 a/r. The thing is it's smaller than a t3 it is a garrett same exhaust flange just smaller. so I'm tryin to figure it out before it goes up for sale so I don't present it as the wrong thing. I would post pics but don't knw how.

 

probably a t25.
