HKS Actuator Upgrade Kit Subaru Impreza
By just installing the kit to normal turbine, you can get more power, and it's very cost-effective.
Easy power up
You can get more power and higher boost just by changing the normal turbine installed actuator.
Cost-effective
You can use existing turbine for the first step of the tune-up.
Adjustable boost pressure
You can adjust boost pressure for your needs with rod that is installed to the actuator by expansion and contraction.
Precautions
When you just want to increase the supercharging pressure, there is risk of damaging the engine by fuel insufficiency. So for the high supercharging pressure setting, you should use fuel cut defencer(FCD) or fuel control system (F-CON).
It is an easy and affordable boost up solution without EVC.
For vehicles with EVC or other boost controllers, the upgraded actuator will solve "boost drop at high rpm" that is a week point of GDB.
Features
● Easy boost up with stock solenoid.
Quicker boost increasing than stock actuator. As it can be used with stock ECU, it enables affordable upgrade from intake and exhaust tuning specification.
*This is in-house test result. You might need to set the ECU depend on the other installed parts or vehicle spec.
● Using with EVC would solve the problem of boost drop at a high rpm.
By using with EVC, it will prevent boost drop at high rpm by EVC rpm correction setting and improves peak power.
With F-CON iS, stock turbine can produce ultimate boost up.
"Boost spooling characteristic" can be adjusted by EVC. (Test was done with a restrained over shoot)
Stock solenoid controllable. Not compatible with limited model and Spec C.
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.
