BorgWarner Cartridge SX S200SX 46/61mm

This is the BorgWarner S200SX turbo cartridge, part number 176639. It's a core component for building or rebuilding a turbocharger system, designed for performance applications where improved airflow and boost are desired. The S200SX series is known for its robust construction and ability to handle demanding conditions, making it a popular choice for custom turbo setups.

The cartridge features a 46mm compressor wheel inducer and a 61mm turbine wheel exducer. This specific sizing is often chosen for its balance between quick spool-up and the capacity to move a significant amount of air, which can lead to noticeable power gains when properly tuned. BorgWarner uses well-made materials and precise manufacturing to ensure the components within the cartridge, like the bearings and seals, can withstand the high temperatures and rotational speeds inherent in turbocharger operation. This cartridge is designed to be a direct replacement for the center housing rotating assembly (CHRA) in compatible S200SX turbocharger frames, simplifying the rebuild process.

When installing a turbo cartridge, it's crucial to ensure the oil supply is clean and properly lubricated, as the bearings rely heavily on this. Many builders also opt to replace associated seals and gaskets during a turbo rebuild. This cartridge is a solid option for those looking to restore performance to an existing turbo or to build a custom unit for a project vehicle.
