g42 1200 turbo kit mods upgrade

Garrett® G 42 Series turbochargers offer enthusiasts a new range of quick spooling, high horsepower solutions for 2.0 liter up to 8.0 liter engine platforms. The G42-1200 Compact, G42-1200, and G42-1450 turbochargers produce up to 1450 horsepower thanks to the ten blade, forged, fully-machined G Series compressor wheel with high flowing aero. These low inertia compressor wheels are smaller in size and weight resulting faster boost response.
