Garrett G Series G35-900 Turbo

Get More Power With the Garrett G Series G35-900 Turbo

Garrett's G35-900 is really the sweet spot for the G35 turbos. The turbo brings one of the best blends of usable power and responsiveness that Garrett has ever offered. While the G35-1050 is an option that will deliver more power, the G35-900 is really the turbo to buy. 

This turbo is an all-new, clean slate design. A 3576 rotor group, this is the successor to the 35-size turbine with a 76mm billet compressor wheel. The G35 features all-new G Series compressor wheel aerodynamics, along with a Mar-M turbine wheel material rated up to 1050° C | 1922° F in one piece center housing and backplate for increased durability. It has 4 water jacket ports for customizable coolant port installation plus a fully machined speed sensor and pressure ports. 

This turbo has a one-piece center housing and backplate for increased durability. It is available in standard and reverse rotation configurations to fit a multitude of installations. Oil restrictor and water fittings are included with the purchase. It is also now available in twinscroll 1.06 a/r.

G35 Compressor Aero

Forged fully-machined compressor wheel and new aerodynamics increase maximum horsepower output and boost response. The computational fluid dynamics (CFD) engineered compressor wheel increases airflow up to 15% for 60mm and 30% for 67mm with 79-80% efficiency (compared to GTX Gen II).

Available in standard rotation and reverse rotation options for enthusiasts that want the perfect twin turbo installation or a single reverse rotation turbo for applications with installation restrictions.

Speed Sensor

The compressor housing features a fully machined ported shroud to help reduce compressor surge. A fully machined speed sensor port provides enthusiasts the option to add the new G Series speed sensor to measure turbocharger shaft speed, a key factor in determining ideal operating conditions.

The new speed sensor is easy to install and does not need to be adjusted for length like previous sensors. Simply remove and plug, then insert the speed sensor and tighten the bolt. The new speed sensor is sold separately and is not compatible with GT and GTX sensors due to the new design and sizing.
The addition of an o-ring between the compressor housing and backplate reduces the possibility of boost pressure leakage.

Center Housing

A new one-piece center housing and backplate increase durability and product safety by reducing the number of failure points associated with the turbocharger. The center housing to turbine housing v-band connection allows for 360-degree orientation when installing with Garrett non-wastegated turbine housings.

Water Jackets

Four large water jacket ports increase cooling capacity and allow enthusiasts to customize water line routing to help improve the installation process. The turbocharger comes with two -6AN water fittings and two plugs.

*Recommended to install waterlines on opposite sides of the housing.

Oil Passage

A single-stage oil passage directs pressurized oil to the new oil cavity ensuring proper bearing lubrication at both sides of the cartridge. Each turbocharger includes (1) -4AN oil restrictor fitting with a 1mm orifice to provide the turbo with the recommended 40psi of oil pressure.

Rotating Group – Twin Piston Rings

A shorter bearing cartridge allows us to incorporate twin piston rings on both sides of the shaft wheel assembly. This will reduce the likeliness of oil leakage at the seals from the center housing to the compressor and or turbine stage.

Turbine Wheel Aero

The turbine wheel features all new aerodynamics to improve flow and boost response. The new turbine wheel is made of Mar-M super alloy and is capable of handling exhaust gas temperatures up to 1050 degrees C.  The G35 turbine wheel flows 15-20% more than GTX35 and has a peak efficiency of 74%.
