THE GARRETT G SERIES G40-900 TURBO BRINGS BIG POWER IN A MID-FRAME TURBO
Garrett’s all-new G40 mid-frame turbochargers are engineered for 2.0L - 6.0L engine displacements and are capable of supporting from 500 - 1150 horsepower. G Series G40 is offered in two sizes depending on the performance targets of the engine: G40-900 (62mm compressor inducer) and G40-1150 (71mm compressor inducer). Stainless steel turbine housings are available in T4 divided inlet and V-Band inlet configurations.
While the G40-1150 certainly has its place in the lineup, the G40-900 is a excellent choice if you need lower backpressure and up to 82lb/min in the mid-frame footprint. The 900 is a step up from the G35-900, giving you a lower backpressure option at that power output. If you need 1000+hp (more power than the G40-900 can support) then the G40-1150 is ready to get the job done

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 provide 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.
