Hey mate, sorry for the late reply, I have no net access at work. Exploration drilling in the middle of no-where for two weeks.

Anyways, heres some specs off the turbo from the Monsta Turbo page on eBay:
The turbo offers the low inertia and fast boost response of the light weight T3 Turbine wheel and the high airflow characteristics of the T70 compressor. Air flow rating of up to 800HP 3" Inlet Diameter : 2" outlet : Wet Floating Bearings : 1/8 NPT oil inlet
T3 Flange : Fits T3 and T3/T4 Manifolds

Im wanting $500 including postage anywhere in Aus for the whole setup.
