HKS GT II Sports Turbine Kit

GT II turbine is HKS original turbine developed along with the engine deveopment and designing which is replaceable for stock engine. We designed wheel and housing for each engine characteristic and tested over and over to develop better products and new technology.

• Factory Replacement Type Sports Turbine Kit for SUBARU EJ20/25 Single Scroll Turbine.
• Compared to the existing kit 11004-AF010, EJ20 engine is the main target of this kit; therefore, A/R of the exhaust housing is 0.67.
• The ball bearing turbine of this kit was originally designed by HKS. Enlarged turbine wheel increases air volume. The ball bearing can reduce response loss. Also, the bypass port was also enlarged to reduce load to the engine and restrict the exhaust pressure increase at high engine rpm.
• This turbine kit includes all necessary parts in order to install the kit such as an actuator, oil outlet pipe, etc. (There may be parts necessary to purchase separately, and parts modification is required in order to install this kit.)

There were many famous turbines in HKS' History. And that's the history of the tuning itself. HKS have been optimizing those turbines for each automobile and with other necessary parts they made tuning kits for small tune-ups to super high-power tune-ups. HKS' turbine kit can fulfill your desire of tune-ups.

HKS turbine kits are developed under the tough situation such as street or motor sport competition. We have tested in all situation of driving environment and collected the data. All these exploitation lead them to develop the world's best tuning turbine kit.
