Genuine Garrett GT30 hybrid turbo with internal wastegate.

Similar in spec to a GT3076R but with a larger trim compressor wheel to the likes of the ATP3076R. I think it's the same as HKS GT3037S i.e. 56 trim as opposed to 52 trim

Genuine Garrett T04S compressor cover with 4" inlet 2.5" outlet.

0.86 A/R turbine housing

Built for me by Owen Developments who are Garrett's European Performance centre.

Spools up rapidly on my 2.4 Fiat Coupe 20V Turbo - I get 1 bar boost by 3200rpm in 3rd and 2800rpm in 6th. I've made 420BHP at the wheels, 430lbs/ft @1.25 bar boost on it. I have a higher boost fuel map (1.65 bar) but have never had it dyno'd it with that map.

Has done just 4000 miles.
