What is the A/R ratio, and why does 1.45 matter?

The A/R ratio (Area/Radius) on a turbine housing measures the cross-sectional area of the housing relative to its radius. A larger A/R ratio, like the 1.45 found here, generally allows for better exhaust gas flow at higher RPMs, which can help sustain boost and improve top-end power in performance engines.

What type of exhaust manifold flange does this housing use?

This BorgWarner turbine housing utilizes a T6 inlet flange. This is a common and robust flange standard used on many larger performance turbochargers, designed to handle significant exhaust flow.

What are the implications of this housing not being CARB approved?

If a part is not CARB approved, it means it has not met the emissions standards set by the California Air Resources Board. Consequently, this part cannot be legally shipped to or installed on vehicles registered in California.

Product Details

This listing is for a BorgWarner S500SX turbine housing, featuring a 1.45 A/R ratio and a T6 inlet flange. It's designed to work with a 110mm turbine wheel, making it a solid choice for serious performance builds where airflow and exhaust gas management are critical. This housing is a key component for anyone looking to build or upgrade a high-horsepower turbo system.

Crafted from durable cast iron, this housing is built to withstand the extreme temperatures and pressures found in high-performance forced induction applications. The 1.45 A/R ratio is on the larger side, which generally means it's optimized for better top-end power delivery and sustained boost at higher RPMs, making it suitable for engines that operate in their upper rev range. The T6 inlet flange is a common standard for larger turbochargers, ensuring good compatibility with a wide range of exhaust manifolds designed for this size.

When considering a turbine housing of this caliber, it's important to match it with the appropriate turbocharger center section and exhaust manifold to achieve your desired performance goals. This housing is intended for custom turbocharger builds and performance applications where precise airflow control is paramount. Please note that this part is not CARB approved and cannot be shipped to California.
