I've just had my turbo in pieces getting it ready to have the compressor outlet pipework modified to suit it's new application. While it was in bits i took the opportunity to measure it up to see what it actually was.

I was under the impression it's an externally wastegated GT3071R but now i think it's some kind of hybrid gt3071 exhaust side but gt3076 compressor side.

Measurements are as follows

Compressor
inducer 57mm
exducer 76.12mm (probably 76.2mm)
A/R 0.6
4" inlet with ported shroud
2" outlet

Turbine
wheel diameter 58mm (not accurately measured as I can't get the exhaust side apart at the moment)
A/R 0.6 (i think... see photos below)
3" outlet

Tial 38mm external wastegate

on the turbo to manifold flange this number is visible 1679-6









I presume this 0.6 marking in the photo below is the turbine A/R ?



Is it just what i think it is, a cross between the gt3071 and gt3076?

What kind of BHP figure would this turbo be capable of?

Cheers in advance to the pf gurus

Oh and for the record it's on a 1000cc Kawasaki ZX10R motorbike engine.
