Garrett G Series G40-1150 Twin Scroll Turbo Brings a Lot of Power

Garrett’s all-new G40 mid-frame turbochargers are engineered for 2.0L - 6.0L engine displacements and support 500 to 1100 horsepower.  One of our favorite turbochargers for the 1000+hp range, the G40-1150 (71mm compressor inducer) brings big power in the G40 mid-frame turbo size. It's a step up from the G40-900, and is the turbo to get if you need more horsepower than that turbo can deliver.  Stainless steel turbine housings are available in T4 divided inlet or Vband inlet configurations and are fully interchangeable.

About Garrett G-Series Series Turbochargers

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.

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 watercooled 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.
