Introducing performance out of a package you never thought possible. This clean sheet product is tailored to meet the demands of hardcore racing enthusiasts while providing industry leading power capability in a small package.
The G-Series G25-550 and the G25-660 turbochargers are compatible with 1.4L - 3.0L engine displacements and capable of producing up to 550 and 660 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.
A new name designates a new generation of industry leading technology and innovation.
A clean-slate ball bearing turbo with state of the art aerodynamics, this turbo is smaller and outflows all comparable products on the market. New compressor and turbine aero combined with exotic high temperature alloys allowed engineers to push the limits of performance.
Carrying nothing over from the old gen GT/GTX – the G-series 67mm exducer billet compressor wheel redefines what we thought was possible for a given airflow range – flowing +12 lbs/min (+24.5% gain) compared to the outgoing GTX2867R Gen II turbo it supercedes.
Max turbo speed is 165krpm and max temp is 1050C/1922F. G25 Compressor housings use a traditional 3in inlet and 2in hose outlet with fully machined Speed Sensor Port. The Improved ported shroud inlet design offers maximum surge-resistance with huge flow rates in a compact outline.
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.
Sold as Complete Assembly with Supercore and Turbine 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.
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.
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.
