The G-Series G25-550 turbocharger is compatible with 1.4L - 3.0L engine displacements and capable of producing up to 550 horsepower. G Series 25 turbochargers are smaller and outflow all comparable products on the market.

New compressor and turbine aero combined with high temperature resistant materials allowed engineers to push the limits of performance.

Compressor Aero
Forged fully-machined compressor wheel and new aerodynamics increase maximum horsepower output and boost response. The compressor wheel increases air flow up to 15% for 60mm and 30% for 67mm with 79-80% efficiency (Compared to GTX GenII). 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.

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.

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.

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°c.

Turbine Housings
All G Series Turbine housings are made from stainless steel to provide ultimate durability and temperature resistance up 1050°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.
