Garrett G-Series G25-660 turbocharger

The Garrett G-Series G25-660 is a cutting-edge performance turbocharger engineered for small-displacement engines, offering an exceptional balance of high-airflow potential and rapid transient response. Featuring the latest G-Series aerodynamics in both the compressor and turbine wheels, this unit provides industry-leading efficiency for its size class. Its compact architecture, combined with a water-cooled center housing and integrated speed sensor port, makes it a premier choice for serious street-performance builds and competitive motorsports applications where space is at a premium and maximum power-to-weight ratio is required.

Fitment & Technical Note:

• Application: This is a universal, high-performance unit requiring a custom turbo system setup. It is not a direct-fit replacement for any production vehicle. Proper integration requires bespoke fabrication of the exhaust manifold, downpipe, and oil/coolant plumbing.

• Performance Capability: The G25-660 is designed for engines capable of producing up to 660 horsepower. It is essential that your engine's internal components, cooling system, and fueling architecture are professionally validated to handle the increased load and thermal demands of this power level.

• Installation: For reliable operation, ensure the use of high-quality synthetic oil and verify that the oil drain path is clear and gravity-fed to prevent back-pressure. Utilizing a professional-grade ECU for boost control and data logging is highly recommended to monitor air-fuel ratios and intake temperatures during initial mapping and tuning.
