Garrett G25-700 GEN II

The G-Series II is the latest generation of Garrett Performance Turbochargers / G25-700 Gen II

Power Range: Up to 700 HP
Displacement: 1.4 to 3.0 liters

A true evolution of the original G-Series

With the G-Series II, Garrett further refines its performance turbocharger range, delivering increased airflow, higher efficiency, and greater power potential while maintaining the compact footprint and fast response the G-Series is known for.

Designed for high-output road and motorsport applications, the G25-700 Gen II represents a direct evolution rather than a redesign, building on proven architecture with advanced aerodynamics and improved flow characteristics.

Let’s stick to the facts:

New Gen II compressor aerodynamics with up to 10% higher airflow compared to G-Series Gen I at maximum pressure ratio

Increased efficiency at high flow rates for improved power potential

High-flow compressor housing with preparation for optional turbo speed sensor

Mar-M turbine wheel, resistant up to 1050°C

Stainless steel turbine housing, resistant up to 1050°C

Dual ceramic ball bearing CHRA for fast spool and reduced friction

Four water connection options for flexible installation

Dual piston ring seals on both sides

V-Band turbine inlet and outlet

Uses Gen I compressor and turbine housings for full compatibility

Available in standard and reverse rotation.
