Fitment Information:

The BorgWarner S300 SX-R 8476 SuperCore Assembly is a universal performance turbocharger core designed for custom turbocharger builds and applications where compatible turbine housings and supporting components are selected separately.

Compatible applications include high-performance diesel and gasoline engines requiring custom turbocharger configurations, including but not limited to:

• Cummins diesel performance applications
• Custom turbo builds using T3, T4, and V-band turbine housing configurations
• High-performance street, race, and competition applications

Proper turbine housing selection, exhaust manifold configuration, engine specifications, and supporting modifications are required for installation. This super core does not represent a direct bolt-on replacement unless paired with application-specific turbine housing and supporting components.

Compressor Specifications:

• BorgWarner 4-inch inlet compressor housing
• 2.5-inch compressor outlet
• Port shroud map width enhancement
• Pre-tapped compressor cover for speed sensor and pressure port installation
• Additional drilling through required for installation of sensors and accessories
• 64.0mm inducer compressor wheel
• 84.0mm exducer compressor wheel
• Black anodized forged milled (FMW) billet compressor wheel
• Extended tip technology design

Optional Compressor Discharge Options:

• Factory turbo configuration uses a 2.5-inch hose outlet
• Optional 2nd Generation machined V-band discharge available for 1994-2002 Ram Cummins 5.9 applications
• Optional 3rd Generation welded elbow available for 2003-2007 Ram Cummins 5.9 applications

Optional T51R Mod:

The optional T51R modification is a compressor housing modification designed to increase turbocharger sound by amplifying turbocharger whistle and compressor noise. The modification is completed after the order is placed and requires additional machining time.

The T51R modification typically adds approximately 1-2 weeks before shipment. Additional finishing options such as ceramic coating or polishing may require additional processing time beyond the standard production schedule. Due to the labor-intensive machining process, delays beyond estimated timelines may occur.

Each order is carefully prepared to ensure the highest quality components and proper shipping preparation.
