BorgWarner Cartridge SX S300SX3 66/73mm

This is the BorgWarner S300SX3 turbo cartridge, part number 176650. It's a well-built component designed for those looking to upgrade or rebuild their forced induction system. This cartridge is built around a 66mm compressor wheel and a 73mm turbine wheel, offering a balance of airflow and responsiveness for a wide range of performance applications. The S300SX3 series is known for its robust construction and reliable performance, making it a popular choice for serious tuners and builders.

The core of this turbo cartridge features a high-flow compressor cover and a durable turbine housing. Inside, you'll find advanced bearing technology that helps ensure smooth operation and longevity, even under demanding conditions. The precision-machined wheels are designed to move a significant amount of air, allowing your engine to breathe better and produce more power. BorgWarner has a long history in turbocharger technology, and this cartridge reflects that expertise, offering a solid foundation for a custom turbo setup. It's important to note that this is a cartridge only, meaning it's the center housing rotating assembly (CHRA) and will need to be integrated into your existing or custom turbocharger plumbing and housings.

When installing a turbo cartridge like this, proper oil and coolant supply lines are critical for lubrication and temperature control. Ensure your system is clean and free of debris before installation to prevent damage to the new cartridge. This component is ideal for custom builds where precise control over airflow and boost is desired. It's a well-made piece that can handle significant power increases when properly matched with supporting modifications.
