turbo i.d. help (wheel dimensions inside)

[eiuskoalman]

i've got a turbo from a recent TR purchase i'd like help i.d.'ing. i know its not stock or a 49, the inlet is cast into the compressor side. the major diameter of the comp. wheel measures 3", there are 2 different blade (i guess thats whatcha call them) sizes, 7 of each size. the outlet on the exhaust side measures 2 9/16" so i'll assume the wheel measures about 2 1/2". the compressor housing is a garrett and is labeled A/R .60 M24. the only noticable marking on the exhaust side is inside the inlet, stamped .82. so, what do i have here? thanks again, Aaron

edit: just noticed the center section has 2 seperate raised cross shaped markings casted on it, both with a "T" stamped on them, both located just under the oil feed flange. dont know if its a stock center section or not.

The compressor wheel back-disc of 3" says the comp can be a T04B or T04E comp, with about 10 or so trims to pick from.

The ~2.5" minor diameter of the turbine says that it is most likely the T4 "P" trim.
