sorry for not putting up much info last night was half awake...
billet compressor wheel. It flows 88lb/min
compaired to gt4294r or gt4202r
The turbine inlet is slightly different than a t4 bolt pattern. You can still get the t4 manifold to work just fine by enlarging the bolt holes.
I think its 67mm Comp / 72mm Turbine but I have to double check
