I have this rather special turbo available at the moment, Garrett GT4094/42R hybrid. Its a hybrid turbo that AET Turbos put together, its basically a combination of a GT4094R and a GT42RS using the body of a GT40 with a GT42 compressor wheel installed with a 4" V band flange on the T4 exhaust housing.
I was using this turbo on my own car until very recently proving to be 100% reliable in Time Attack and managed to produce 860bhp at 1.6 bar with more to come from it if needed. Very nice turbo this one, all in good working condition, £650
Any questions just ask.
