What exactly is a CHRA?

CHRA stands for Center Housing Rotating Assembly. It's the core of a turbocharger, containing the turbine wheel, compressor wheel, shaft, and bearings all housed together. You typically need to attach separate turbine and compressor housings to complete the turbocharger.

What materials are used in the G42-1585 CHRA?

The turbine housing is constructed from high-nickel, ductile iron, known for its resistance to high temperatures. The compressor wheel is made from forged aluminum billet, offering a good strength-to-weight ratio.

What else do I need to complete a turbocharger using this CHRA?

To use this CHRA, you will need to acquire compatible turbine and compressor housings that match your specific performance goals and engine setup. You'll also need all the necessary oil and coolant lines, exhaust manifold, downpipe, and intake plumbing.

About this part

Product Details

What you get with this Garrett G42-1585 G-Series II CHRA is the core assembly itself, ready to be integrated into your custom turbocharger setup. This is the central rotating assembly, including the turbine and compressor wheels, shaft, and bearings, all housed within their respective housings. It’s designed for builders and tuners who need a high-performance core for a custom turbo application, offering a robust foundation for significant airflow and power gains.

The G42-1585 is a serious piece of hardware, built for demanding performance builds. It features Garrett’s advanced G-Series II aerodynamics, which are known for improved efficiency and airflow compared to previous generations. The turbine housing is cast from a high-nickel, ductile iron material, giving it excellent durability and resistance to high temperatures, a critical factor when dealing with the extreme conditions of a performance engine. The compressor side utilizes a forged-aluminum billet wheel, which is both lightweight for quick spool and strong enough to handle high boost pressures. This CHRA is designed to be a direct replacement for the core in a Garrett G42-1585 turbocharger, making it a straightforward component for a turbo rebuild or a custom turbo build where you're sourcing the housings separately.

When planning your build, remember that a CHRA is just the core. You'll need to source compatible turbine and compressor housings, along with all the necessary plumbing, oil and coolant lines, and mounting hardware to complete the turbocharger assembly. This component is intended for experienced builders who understand the complexities of custom forced induction systems. Ensure you have the correct supporting modifications for your engine to take full advantage of the airflow this turbocharger core can provide.
