Garrett G Series G25-660 Turbo

G Series turbochargers feature the latest innovations in turbocharger technology. Advanced compressor and turbine aero offer enthusiasts a wide range of performance boosting solutions for 2.0L - 12.0L engine platforms. Available in a variety of turbine housing options, it’s easy to select the right turbocharger for your application. To make choosing the right turbo easier, the G Series naming convention includes the maximum rated horsepower. For example a Garrett G37-900 is rated at 900 BHP.

Featuring the latest advanced ultra high flow aerodynamic designs with the Garrett G Series Turbine Wheel, the G Series models offer previously unobtainable improvements in spool and power levels by frame sizeThe G-Series Turbine wheel is constructed of Mar-M super alloy material. This material is designed to withstand up to 1050° C - that’s 200 degrees more than inconel turbine wheels! The newly engineered turbine wheel with optimized G Series aerodynamics increases flow up to 15% (Compared to GTX Gen II) more than the GTX and has a peak efficency of 74%.

All G-Series utilize a V-Band turbine housing to CHRA connevtion. This improves the ease of installation, clocking, and servicing the turbocharger. Each turbocharger includes a -4AN oil restrictor fitting with a 1MM restriction orifice to provide the turbo with the reccomended 40PSI of oil pressure. 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 fittings and two plugs.
