What is included in this HKS turbo kit?

This kit includes the HKS SYMMETRY TURBINE GT5565 BB turbocharger with a 3-bolt exhaust housing (A/R 0.73) and ball bearings. Installation components are also included as per the manufacturer's instructions.

What does the A/R ratio of 0.73 mean for this turbo?

The A/R ratio (Area/Radius) of 0.73 on the exhaust housing helps to control the flow of exhaust gases into the turbine wheel. This specific ratio is selected by HKS to provide a balance between quick spool-up and efficient high-RPM airflow for performance applications.

Can this turbocharger be used in California?

No, this HKS turbocharger is not CARB approved and therefore cannot be legally shipped to or installed in California.

Product Details

This HKS SYMMETRY TURBINE GT5565 BB turbo kit includes the GT5565 turbocharger itself, featuring a 3-bolt exhaust housing with an A/R ratio of 0.73. It also comes with the necessary components for installation, as detailed in the manufacturer's instructions. This is a serious piece of equipment designed for those looking to significantly increase their vehicle's power output through forced induction.

The GT5565 turbocharger is built with ball bearings, which help reduce friction and improve spool response compared to traditional journal bearing turbos. This means you can expect a quicker build-up of boost pressure, leading to a more immediate power delivery when you get on the throttle. The 3-bolt exhaust housing is a common mounting pattern, and the 0.73 A/R ratio is chosen to balance exhaust gas flow with turbine speed for optimal performance across a broad RPM range. This kit is intended for custom applications where significant horsepower gains are the primary goal.

When installing a turbocharger of this caliber, it's crucial to ensure your engine's supporting systems are up to the task. This includes proper fuel delivery, engine management tuning, and robust cooling. Because this turbocharger is not CARB approved, it cannot be legally shipped to California. Always consult the included installation manual and consider professional tuning to safely achieve the performance potential of this HKS turbocharger.
