The G-Series G25-660 turbochargers are compatible with 1.4L - 3.0L engine displacements and capable of producing up to 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.

Understanding the Name G25-660:
  • G designates 81 years of Garrett heritage.
  • 25 classifies the size of the frame.
  • The remaining 3 digits identify the max horsepower rating of the turbocharger. (ie 660).

Forged fully-machined compressor wheel and new aerodynamics increase maximum horsepower output and boost response. The CFD (computational fluid dynamics) engineered compressor wheel increases air flow up to 15% for 60mm and 30% for 67mm with 79-80% efficiency. (Compared to GTX GenII). 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. The new speed sensor is easy to install and does not need to be adjusted for length like previous sensors. Simply remove and plug, then insert the speed sensor and tighten the bolt. The new speed sensor is sold separately and is not compatible with GT and GTX sensors due to the new design and sizing. The addition of an o-ring between the compressor housing and backplate reduces the possibility of boost pressure leakage.
