Garrett G Series | G40-900 Turbo

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. All are interchangeable with both super cores. 

While the G40-1150 certainly has its place in the lineup, the G40-900 is a excellent choice at this mid-frame size. The 900 is a step up from the G35-900, giving you a lower backpressure option at that power output. If you need more power than the G40-900 can provide, then the G40-1150 is ready to get the job done, but don't go straight there without making sure the G40-900 will get you everything you need. In many cases, it'll do just that and more.
