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 new turbine wheel flows 15-20% more than GTX and has peak efficiency of 74%.
All G Series Turbine housings are made from stainless steel to provide ultimate durability and temperature resistance up 1050 degrees C. Internally wastegated housings are compact, efficient, and designed with maximum bypass port size to reduce boost creep and provide better boost control. Turbine housings are available in a variety of wastegated and non-wastegated, open volute, T25 and Vband configurations so be sure to order the correct part for your application. Wastegated turbine housings do not include actuator assembly kit.
The G Series turbos are 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.
