BorgWarner Cartridge S500SX-E SX-E 94mm (120/110)

This is the BorgWarner S500SX-E turbo cartridge, part number 15007105016. It features a 94mm inducer compressor wheel and a 120/110 turbine wheel specification, designed for high-performance forced induction applications. This cartridge is a core component for building or rebuilding a custom turbocharger setup, offering a robust foundation for significant power gains when properly matched to an engine's needs and airflow requirements.

The S500SX-E series from BorgWarner is known for its well-built construction and advanced aerodynamic designs. This particular cartridge utilizes a 94mm compressor wheel, which is capable of moving a substantial amount of air, making it suitable for larger displacement engines or those seeking to achieve higher boost levels. The turbine side, specified as 120/110, indicates the exducer and inducer diameters of the turbine wheel, crucial for matching exhaust flow to the compressor's capabilities and determining the turbocharger's spool characteristics and overall efficiency range. This cartridge is designed to be integrated into a complete turbocharger assembly, requiring appropriate housings for both the compressor and turbine sides, as well as a center housing rotating assembly (CHRA) that houses the bearings and oil/water cooling passages.

When building a custom turbocharger with this cartridge, careful consideration must be given to the selection of compressor and turbine housings to achieve the desired performance curve. Factors such as engine displacement, intended RPM range, and boost pressure targets will influence the optimal housing sizes. This BorgWarner cartridge represents a significant investment in a high-performance turbo system, and its successful implementation relies on precise engineering and matching to the specific application. It is intended for experienced builders and tuners who understand the complexities of turbocharger system design and integration.
