What does the A/R ratio mean for this turbine housing?

The A/R ratio (Area over Radius) of 0.96 indicates the size of the exhaust housing's volute. A lower A/R generally leads to quicker turbo spool-up at lower RPMs, while a higher A/R helps sustain power at higher RPMs. This 0.96 ratio offers a good balance for many performance applications.

What type of turbocharger does this housing fit?

This turbine housing is designed for T4 flanged turbochargers. The specific wheel size it accommodates is 66mm. It's important to verify that your turbocharger uses a T4 flange and is compatible with a 66mm wheel for proper fitment.

Is this turbine housing street legal in all states?

No, this part is not CARB approved and therefore cannot be shipped to California. It is essential to check your local emissions regulations before purchasing and installing this component.

Product Details

This listing is for a Turbosmart B Frame T4 turbine housing with a 0.96 A/R ratio and a 66mm wheel size. This component is crucial for controlling exhaust gas flow into the turbocharger's turbine wheel, directly impacting boost response and overall engine power delivery. The A/R ratio of 0.96 is a moderate setting, generally offering a good balance between quick spool-up at lower RPMs and sustained power at higher engine speeds.

Crafted with durability in mind, this housing is built to withstand the high temperatures and pressures associated with forced induction systems. Its cast iron construction offers solid thermal resistance, making it a reliable choice for performance builds. The T4 flange ensures compatibility with a wide range of T4 turbochargers, and the 66mm wheel size is often selected for applications seeking improved airflow over stock while maintaining reasonable response characteristics. This housing is a well-built piece that can help you fine-tune your turbo system's performance.

Please note that this part is not CARB approved and cannot be shipped to California. Always consult your turbocharger manufacturer's specifications to ensure this housing is the correct match for your specific turbocharger and intended application.
