I bought this GT4576 brand new to run on my 275 drag radial car, rules have changed for next year so my loss is def your gain!
This 76mm is "rated" @ 1250hp, I have see them make more. The turbo is dual ball bearing, has a billet machined impeller wheel, ported exhaust housing, 1.44 a/r, t4 flange, anti surge compressor housing, and is water and oil cooled. I have the v-band for the exhaust and the aluminum exhaust flange to weld to, I will also include a raw t4 flange in case your are making your own hot side.
Call Precision, do some searching... Turbo with extra's is almost 3 grand, found one used yesterday for #2,300.00.

I will take nothing less than 1,800.00, or trade for a GT47 88mm
Turbo has never been used, just mocked up!!!
