what turbos have a 2.75x3.25 bolt pattern where manifold bolts to turbine housing? i have a turbonetics turbo lying around and dont remember what it was. on compressor housing it has numbers 20192. ill post pics later. if anyone has specs on this it would be helpful too. thanks.

 

Sounds like a T4 turbine inlet flange to me....with those dimensions you gave.

i have nothing better to do with my life then read these forums. i'd also say maybe a .63a/r or maybe even .82
