What is a super core assembly?

A super core assembly is the central rotating part of a turbocharger. It includes the compressor wheel, turbine wheel, and the shaft that connects them, ready to be installed into custom housings for a complete turbocharger.

What vehicles is this designed for?

This super core assembly is designed for custom forced induction builds. It is not a direct-fit turbocharger for a specific vehicle model but rather a component for enthusiasts building their own turbo system.

Why is the compressor wheel made of forged aluminum?

Forged aluminum is used for the compressor wheel because it offers a strong yet lightweight construction. This helps the wheel to spool up quickly and efficiently handle the air being compressed.

Product Details

The BorgWarner EFR B2 7670 Super Core Assembly features a forged-performance aluminum compressor wheel. This is a key component for anyone building a custom forced induction system where precise control and robust performance are paramount. It's designed to be the heart of a turbocharger, housing the essential rotating assembly – the compressor wheel, turbine wheel, and the shaft connecting them – ready for integration into a custom turbocharger housing setup.

This assembly is built with performance in mind, featuring a 76mm compressor wheel and a 70mm turbine wheel. The forged aluminum construction of the compressor wheel offers a good balance of strength and light weight, crucial for quick spool and efficient airflow. The turbine side is designed for durability and efficient exhaust gas management. This core is intended for builders who need a reliable, high-performance rotating assembly to build their own custom turbocharger, allowing for specific housing selections to match engine requirements and desired boost characteristics.

When building a custom turbo system, selecting a well-built core like the EFR B2 7670 is critical. It’s the foundation upon which your entire turbocharger’s performance will be based. Ensure you have the correct turbine housing and compressor cover to match your engine's displacement, power goals, and desired boost curve. This assembly is not CARB approved and cannot be shipped to California.
