Garrett G Series G25-550 Reverse Rotation Turbo

Garrett’s G25-550 is the smallest turbo in the G-Series turbocharger lineup, but don't let that dissuade you. For its size, it makes plenty of power and spools fast. A clean-slate ball bearing turbo with state-of-the-art aerodynamics, this turbo is more compact yet 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 60mm exducer billet compressor wheel redefines what we thought was possible for a given airflow range—flowing +10 lbs/min (+22% gain) compared to the outgoing GTX2860R Gen II turbo it supersedes.

• Compressor Wheel Exducer: 60mm
• Compressor Wheel Inducer: 48mm
• Compressor Wheel Trim: 65
• Compressor Wheel Material: Forged Billet Aluminum Alloy
• Compressor Wheel A/R: 0.70 A/R
• Max Flow Rate: 50 lb/min
• Max Recommended Turbo Shaft Speed: 185000 RPM
• Compressor Housing Connections:
• Inlet: 3.0″ Hose Coupler
• Outlet: 2.0″ Hose Coupler

Available in standard rotation and reverse rotation options for applications with installation restrictions. The max turbo speed is 185krpm and the max temp is 1050C/1922F.  The G25 compressor housings use a traditional 3″ inlet and 2″ hose outlet with a fully machined speed sensor port. The Improved ported shroud inlet design offers maximum surge resistance with huge flow rates in a compact outline. It's sold as a complete assembly with supercore and turbine housing.

A new name designates a new generation of industry-leading technology and innovation. In G25-550 “G” designates 81 years of Garrett® Turbo heritage. “25″ classifies the frame size. The remaining 3 digits identify the “max horsepower” rating at the flywheel of the turbocharger (ie 550).

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. The computational fluid dynamics (CFD) engineered compressor wheel increases airflow up to 15% for 60mm with 79-80% efficiency (compared to GTX Gen II).

All G-series turbos utilize a V-band turbine housing to CHRA connection. This improves the ease of installation, clocking, and servicing of the turbo. Each turbocharger includes 1 -4AN oil restrictor fitting with a 1mm restriction orifice to provide the turbo with the recommended 40psi of oil pressure. 4 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 2 -6AN water fittings and two plugs. *Recommended to install waterlines on opposite sides of the housing.*

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 for the ultimate boost control solution for your high-performance turbocharged vehicle? Look no further than the Full-Race's Garrett G25 Electronic Wastegate Conversion Kit and the Electronic Internal Wastegate Controller by DCCDPro.

The Full-Race Garrett G25 Electronic Internal Wastegate Conversion (eIWG) kit replaces traditional boost activated wastegate canisters with a powerful and reliable OEM electronic actuator (stepper motor).  Electronic actuators allow for precise control of the turbocharger wastegate in all conditions - opening the gate when you want it open, and closing the gate when you want it closed. 

The Full-Race eIWG actuator does not rely on boost pressure to operate properly. The actuator is fully controlled electronically. This type of control is much safer than older methods where a popped off wastegate boost reference line could lead to a blown engine. In addition to being safer, the level of control is much better. The actuator supports positions from 5-95% so that boost can be dialed in perfectly. It also removes the need to worry about changing springs, solenoids, hoses and fittings.

The Full-Race EWG-PRO Programmable Wastegate Controller can be paired with the eIWG Boost Control Conversion Kits for the ultimate in user-programmable control. If your ECU does not have an available H-Bridge output the EWG-PRO is fully capable as a standalone controller, or in conjunection with a standard PWM output from your ECU. 

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. As turbocharging continues to grow globally, our unwavering commitment to high standards ensures unrivaled quality, reliability, and performance.
