Garrett 877895-5006S Turbocharger G-Series G25-660, 0.92 A/R, Wastegated

Garrett G25-660 performance turbocharger with a wastegated V-Band turbine housing.

The GARRETT 877895-5006S G25-660 turbocharger is designed with a 0.92 A/R V-Band inlet and outlet in standard rotation, equipped with an internally wastegated housing.

As part of Garrett’s new G Series, it delivers outstanding efficiency and power capability in a compact frame.

Featuring a forged, fully-machined compressor wheel with CFD-optimized aerodynamics, the unit provides up to 15–30% more airflow compared to GTX Gen II turbos.

The turbine wheel, constructed from Mar-M alloy, handles exhaust gas temperatures up to 1050 °C while flowing up to 20% more than GTX designs.
