Garrett G25-585 G-Series II CHRA

What you get here is a Garrett G25-585 G-Series II CHRA, also known as a turbo cartridge. This is the core assembly of the turbocharger, containing the turbine and compressor wheels, along with their housings. It's designed to be a direct replacement for the center section of a compatible Garrett G25-585 turbocharger, allowing you to rebuild or upgrade your existing unit without replacing the entire assembly.

This CHRA features Garrett's G-Series II advancements, which include an updated compressor wheel design for improved airflow and efficiency. The turbine housing is cast from a high-nickel alloy to handle high exhaust gas temperatures, and the aerodynamic design of both wheels is optimized for a broad powerband. It utilizes a dual ball bearing system, which is known for its durability and quick spool response compared to journal bearing setups. This setup also includes an integrated speed sensor port, allowing for precise monitoring of turbocharger speed when used with a compatible sensor and gauge.

When rebuilding a turbocharger, using a genuine Garrett CHRA like this ensures that the critical rotating components are perfectly balanced and matched to the housings. This is crucial for longevity and performance. While this is the core assembly, remember that you'll need to transfer or acquire the turbine and compressor housings, as well as the oil and water lines, to complete the turbocharger assembly. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure optimal performance and lifespan.
