What does the .83 A/R ratio on the turbine housing mean?

The A/R ratio (Area/Radius) on the turbine housing indicates how much air the housing can flow relative to its size. A .83 A/R generally offers a good balance, allowing the turbo to spool up relatively quickly while still supporting strong airflow at higher engine speeds.

What kind of engine modifications are typically needed when installing this turbo?

Installing a turbocharger like this often requires upgrades to fuel systems, engine management tuning, and proper oil supply and return lines. It's recommended to consult with a performance specialist to ensure all supporting systems are adequate for the increased power.

Is this turbocharger suitable for daily driving or only for track use?

While built for performance, the SX S200 with a .83 A/R can be tuned for a wide range of applications, including daily driving, depending on the vehicle and supporting modifications. Its design aims for a usable powerband across different driving conditions.

Product Details

The 46mm inducer wheel on this BorgWarner SX S200 turbocharger is a key detail that tells you this unit is built for serious airflow. It’s designed to move a significant volume of air into your engine, helping to increase power output. This turbo features a T4 turbine housing with an A/R ratio of .83, which balances responsiveness with top-end power. This specific A/R is a popular choice for many performance applications, offering a good compromise between spool time and breathing capacity at higher RPMs.

Constructed with BorgWarner's well-known attention to detail, this turbocharger uses robust materials and manufacturing processes to ensure reliability under demanding conditions. The SX-E series is known for its durability and consistent performance, making it a solid choice for those looking to significantly enhance their vehicle's power. The turbine housing is designed to bolt up to T4 exhaust manifolds, a common pattern in many performance and aftermarket setups. While this turbo is built for performance, it's important to note that it is not CARB approved and cannot be shipped to California.

When installing a turbocharger of this caliber, it's crucial to ensure your engine's supporting systems are up to the task. This includes proper fuel delivery, engine management tuning, and an oil supply and return system that meets the turbocharger's requirements. Consulting with a professional tuner or experienced mechanic is highly recommended to optimize performance and ensure the longevity of both the turbo and your engine.
