So i got this turbo today with a bunch of other stuff. Its got a Turbonetics Compressor housing. The middle part? has a number of 408752. The guy i bought it from was advertising it as a 81mm turbonetics turbo which i do not believe it is.

All the numbers you've found are the part numbers for the individual components, and don't tell you anything about the unit as a whole. The only real part number is the sticker on the backside of the compressor backing plate; if that's missing, post up both the major & minor sizes of both wheels.

Compressor wheel
~82mm
~118mm

Couldn't get the exhaust housing off

 

82mm mid frame or maybe super T - check the turbine wheel measurements and see:

Mine is a t6 exhaust housing. I still can't get it off so I can't measure the wheel yet.

 

T-6 Housing....prob Y2K 82mm

Yup that's it! Awesome thanks a ton. Where can I find more info on it like how much power it will support and stuff like that
