Product Details

What you get with this BorgWarner Super Core assembly is the heart of a high-performance turbocharger system, ready for custom plumbing and turbine housing selection. This is the S300 frame size, featuring the BorgWarner EFR (Engineered for Racing) design, specifically the SX variant with an Integrated Dual Scroll (IDS) housing. This unit is built for enthusiasts looking to build a unique forced induction setup, offering a robust platform for significant power gains when paired with the right components.

The EFR line is known for its advanced aerodynamics and durable construction. The SX series takes this further with features aimed at maximizing airflow and responsiveness. The Integrated Dual Scroll design on the compressor cover helps improve boost control and spool characteristics, especially beneficial in applications where quick throttle response is critical. This super core is designed to be a solid foundation, allowing you to select the exact turbine housing and wastegate configuration that best suits your engine's needs and your performance goals. It’s a well-built piece that’s ready for the serious builder.

Because this is a super core assembly, it requires additional components to become a fully functional turbocharger. You'll need to source the appropriate turbine housing that matches your engine's displacement, exhaust flow, and desired powerband, as well as a compatible wastegate. This approach gives you the ultimate flexibility in tuning your engine's performance. Please note that this unit is not CARB approved and cannot be shipped to California.
