BorgWarner S3A Turbine Housing

If you're building a custom turbo system or replacing a worn-out component on your forced induction setup, a turbine housing is a critical piece. This S3A turbine housing from BorgWarner is built to handle the demands of high-performance applications. It's designed to work with specific BorgWarner turbocharger models, ensuring a proper fit and function when paired correctly.

This housing is constructed from durable cast iron, a material chosen for its ability to withstand the extreme temperatures and pressures found in the exhaust stream of a turbocharged engine. The S3A designation refers to a specific frame size and A/R ratio, which dictates how quickly the turbocharger spools up and the overall flow characteristics. BorgWarner is a well-known name in the turbocharger world, and this housing reflects their experience in creating reliable components for enthusiasts and racers alike. It's important to match this housing to the correct compressor cover and center housing rotating assembly (CHRA) to achieve optimal performance and longevity for your turbo system.

When installing a new turbine housing, it's always a good idea to inspect the exhaust manifold for any cracks or warping, and to ensure the turbocharger's oil and coolant lines are clean and free of debris. Proper installation is key to preventing leaks and ensuring the turbocharger operates efficiently. This part is not CARB approved and cannot be shipped to California.
