What is a SuperCore Assembly?

A SuperCore Assembly contains the essential rotating components of a turbocharger, including the turbine wheel, compressor wheel, shaft, and bearing housing. It serves as the central part around which a complete turbocharger unit is built, allowing for customization of the turbine and compressor housings.

What components are included with this BorgWarner SuperCore?

This SuperCore Assembly includes the aluminum bearing housing, the turbine wheel, the compressor wheel, and the connecting shaft. It does not come with the turbine housing or the compressor cover, which must be sourced separately to complete the turbocharger.

Can this SuperCore be shipped to California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

The aluminum bearing housing on this BorgWarner EFR B2 8474 SuperCore Assembly is a key detail, offering a lighter weight compared to cast iron options. This assembly is the heart of a turbocharger system, containing the essential rotating components like the turbine and compressor wheels, along with the shaft and bearings. It’s designed to be the core around which a complete turbocharger unit is built, allowing for customization and specific application tuning.

BorgWarner's EFR (Engineered for Racing) line is known for its performance focus, and the B2 8474 is a robust option for those building a custom forced induction setup. The assembly features a 74mm compressor wheel and a 70mm turbine wheel, designed to support significant airflow for higher horsepower applications. The bearing system is built for durability under demanding conditions, crucial for sustained performance.

When building a turbocharger around this SuperCore, consider the specific manifold and turbine housing you'll need to match your engine's displacement and desired power band. This assembly is intended for experienced builders and tuners who understand the intricacies of turbocharger system design and integration. It does not include the turbine housing or compressor cover, which are typically selected separately to fine-tune spool characteristics and peak power output.
