What is the A/R ratio, and what does 0.82 mean for my turbo?

The A/R ratio, or area-to-radius ratio, describes the size of the turbine housing's volute. A 0.82 A/R is a moderate size that typically offers a good balance between how quickly the turbocharger spools up and its ability to produce power at higher engine speeds.

What type of inlet and outlet connections does this housing use?

This turbine housing features an open T3 inlet flange, which is a common pattern for many turbocharger applications. The outlet uses a V-band connection, known for providing a strong, leak-free seal to your exhaust downpipe.

About this part

Product Details

If you're looking to upgrade the performance of your forced induction system, this Garrett GBC37 turbine housing kit is designed to help you achieve improved airflow and boost response. This housing is built to work with Garrett's GBC37 turbocharger, offering a specific A/R ratio that balances spool speed with top-end power.

This kit features an open T3 turbine inlet flange, a common and versatile mounting pattern, along with a V-band outlet for a secure and leak-free connection to your downpipe. The 0.82 A/R (area-to-radius) ratio is a well-regarded choice for many applications, providing a good compromise between quicker turbocharger spool-up at lower RPMs and the ability to sustain boost at higher engine speeds. Its well-built construction from durable materials ensures it can handle the high temperatures and pressures found in a turbo system.

Please note that this part is not CARB approved and cannot be shipped to California. Always consult your local emissions regulations before purchasing and installing aftermarket forced induction components.
