Product Description:

Garrett G-Series II G25-585 Turbochargers

High-Performance Turbo for 1.4L - 3.0L Engines | 300-585 HP

Product Overview

The Garrett G-Series II G25-585 Turbocharger is the latest evolution of the high-performance G-Series line, engineered to deliver faster spool, increased airflow, and superior efficiency. Designed for 1.4L to 3.0L engines, this turbo supports 300-585 horsepower, making it ideal for street performance, track builds, and race applications.

Featuring next-generation compressor aerodynamics, the G-Series II provides up to 10% more flow compared to Gen I, improving response and power output. Its easy upgrade path allows existing Gen I users to swap the CHRA without changing housings, ensuring a hassle-free installation.

0.72 A/R (PN: 934076-5002S) – Balanced performance, offering a blend of spool and top-end power.
0.92 A/R (PN: 934076-5003S) – Maximum top-end flow, designed for high-horsepower builds.

👉 Use the dropdown menu to select your preferred A/R ratio based on your power goals!
