Garrett G-Series turbochargers are designed specifically for hard-core enthusiasts who want optimal performance. The forged fully-machined billet aluminum compressor wheels feature next-generation aerodynamics that provides a larger horsepower range and maximize boost response. The G45-1125 in the G45 lineup provides up to 1,150hp to drivers who need a ton of power. If you need more than that, you'll have to go to the G45-1350 or G45-1500.

For all G45s, ported shroud compressor housings increase surge resistance and provide reliable, continuous power throughout the power band. A dual ceramic ball bearing cartridge prolongs the lifespan and improves shaft balance. The water-cooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Inconel, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures, that means you can push your car further than ever before and it will keep performing well.
