Garrett G40 Turbine Housing Kit O/V V-Band / V-Band 0.95 A/R

This is the Garrett G40 Turbine Housing Kit with an O/V V-Band and V-Band connection, featuring a 0.95 A/R ratio. This component is crucial for managing exhaust gas flow into the turbine wheel of your turbocharger, directly impacting spool speed and top-end power. The A/R ratio, which stands for Area/Radius, dictates the cross-sectional area of the volute relative to the radius. A 0.95 A/R generally offers a good balance, allowing for relatively quick spool-up while still supporting significant airflow at higher engine speeds.

Garrett is a well-known name in forced induction, and this turbine housing is built to handle the demands of performance applications. The V-band connections on both the inlet and outlet provide a strong, secure, and leak-free seal, which is essential for maintaining consistent boost pressure and preventing exhaust leaks. This design also simplifies installation and removal compared to traditional flanged setups, making it easier to service or swap components. The cast iron construction is durable and designed to withstand the high temperatures and pressures associated with exhaust gases in a performance turbo system.

This kit is designed for custom turbocharger builds or as a replacement part for existing Garrett G40 turbochargers. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure this housing's A/R ratio and connection type are compatible with your specific turbocharger and engine build goals before purchasing.
