Garrett G Series | G40-900 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.

Featuring the latest advanced ultra high flow aerodynamic designs with the Garrett G Series Turbine Wheel, the G Series models offer previously unobtainable improvements in spool and power levels by frame sizeThe G-Series Turbine wheel is constructed of Mar-M super alloy material. This material is designed to withstand up to 1050° C - that’s 200 degrees more than inconel turbine wheels! The newly engineered turbine wheel with optimized G Series aerodynamics increases flow up to 16% (Compared to GTX Gen II). 

An oil restrictor is recommended for optimal performance with ball bearing turbochargers. An oil pressure of 40 – 45 psi at maximum engine speed is recommended to prevent damage to the turbocharger’s internals. In order to achieve this pressure, a restrictor with a 0.040” orifice will normally suffice, but you should always verify the oil pressure entering the turbo after the restrictor to ensure that the components are functioning properly. Recommended oil feed is -3AN or -4AN line or hose/tubing with a similar ID. As always, use an oil filter that meets or exceeds the OEM specifications.

Computer designed and fully CNC machined, the forged G Series compressor wheel and new aerodynamics design increases maximum horsepower output up to +30%. The new aero design increases peak flow and offers higher power levels within a large operating RPM range.

Looking for a way to protect your turbo or exhaust manifold and improve its efficiency at the same time? Our in-house ceramic exhaust coating does both! Available in black or silver, these 2000+ degree ceramic coatings look great and provide an extra layer of protection against corrosion. By coating the exterior surfaces of your turbo hot side or manifold you retain the heat and energy in the exhaust, not in your engine bay. Improving under-hood temps and increasing efficiency with improved turbo spool are great reasons to add these coatings. Please note that ceramic coating is completed in-house and will add an additional lead time of 1-2 weeks to your order.

Looking to ensure you get the perfect turbo for your unique application the first time? Full-Race is here to help. Our customized turbo matching and system integration services use accurate operating parameter plotting to eliminate guesswork and trial and error.
