BorgWarner Cartridge S300SX-E SX-E 64.5mm (87/76)

This BorgWarner S300SX-E turbo cartridge is a well-built unit designed for performance applications. You're getting the core assembly, which includes the compressor wheel, turbine wheel, and the center housing rotating assembly (CHRA). This cartridge is built around a 64.5mm compressor wheel with an 87mm inducer and a 76mm exducer, paired with a turbine wheel sized for efficient exhaust gas flow. It's a popular choice for those looking to upgrade their forced induction system or rebuild an existing turbocharger.

The S300SX-E series from BorgWarner is known for its robust construction and ability to handle increased boost levels compared to stock turbochargers. The cartridge design means you're replacing the heart of the turbocharger, which can be a more cost-effective solution than replacing the entire unit if the housing is still in good condition. This specific model features advanced aerodynamics in its compressor wheel design, aiming for improved airflow and efficiency across a wider RPM range. The turbine side is also designed to spool up quickly while still supporting higher horsepower outputs.

When installing a turbo cartridge like this, it's crucial to ensure your oil and coolant lines are clean and free of debris. Proper lubrication upon initial startup is essential for the longevity of the bearings. This cartridge is a significant upgrade for many performance builds, and it's recommended to consult with a turbo specialist or experienced mechanic to ensure it's the right fit for your specific engine and power goals. You'll want to make sure your supporting systems, like fuel delivery and engine management, are also up to the task.
