What does the .91 A/R ratio mean for my turbo?

The .91 A/R ratio influences your turbocharger's performance. A higher A/R like .91 generally helps the turbo breathe better at higher RPMs, supporting more top-end power, while still offering a reasonable spool-up time.

What material is this turbine housing made from?

This BorgWarner turbine housing is constructed from durable cast iron. This material is chosen for its ability to withstand the extreme heat and pressure generated within a turbocharger system.

Can this part be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This BorgWarner turbine housing features a .91 A/R ratio and an 80/74mm wheel size, making it a solid choice for building or upgrading forced induction systems. The A/R ratio, which stands for Area/Radius, directly influences how quickly the turbocharger spools up and how much boost it can produce at higher RPMs. A .91 A/R generally offers a good balance, allowing for a responsive feel off the line while still supporting significant airflow for top-end power.

Constructed with durable cast iron, this housing is built to withstand the high temperatures and pressures associated with turbocharging. The 80mm inducer and 74mm exducer wheel dimensions are designed to pair with specific compressor wheels within the S300SX3 family, ensuring efficient flow and performance. This housing is a key component for anyone looking to fine-tune their turbocharger's performance characteristics, whether for racing, performance street use, or heavy-duty applications.

Please note that this part is not CARB approved and cannot be shipped to California. Always consult with a qualified professional to ensure this housing is the correct fit for your specific turbocharger build and application.
