What is a super core assembly?

A super core assembly, often referred to as a CHRA (Center Housing Rotating Assembly), is the central part of a turbocharger. It contains the turbine and compressor wheels connected by a shaft, along with the housing that supports them. This assembly is the heart of the turbocharger and is typically used as a base for custom turbo builds.

What does the 'GXR55-88' designation mean?

The 'GXR55-88' designation refers to the specific Garrett model and wheel sizes. The '55' typically relates to the compressor wheel diameter or trim, and the '88' refers to the turbine wheel diameter. This specific model uses a 0.18-inch trim compressor and a 106TW turbine wheel.

What other parts are needed to complete a turbocharger using this super core?

To complete a turbocharger using this super core, you will typically need to source compatible compressor and turbine housings that match your desired performance characteristics and fitment. You will also need oil and coolant lines, and potentially an exhaust manifold and downpipe designed for your specific application.
