Garrett G25-550 Turbocharger 

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 SPECIFICATIONS

  • 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
 

EXTERNAL WASTEGATE (EWG) AND INTERNAL WASTEGATE (IWG) CONFIGURATIONS AVAILABLE IN BOTH STANDARD AND REVERSE ROTATION

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.

UNDERSTANDING THE NAME

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).

DUAL BALL BEARING CHRA – STANDARD AND REVERSE ROTATION

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.*
