HKS Adjustable Boost Pressure Actuator Upgrade Kit

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).

This strengthen actuator is the first step of the boost up tuning for Lancer Evolution X.
It's an easy boost up tuing because it can be used without an EVC installation.

Features

(1) Boost up without EVC
HKS' electric boost controller "EVC" uses correction maps to control boost of 4B11 engine.
Actuator Upgrade Kit enables boost up without EVC.
Of course, It is possible to use them together.

(2) Safe boost up solution without affection to stock management system.
10kPa (0.1kg/cm2) can be increased from stock boost level. This level does not cause engine check light problem.

(3) Feel boost up effect at partial throttle and high rpm range
Large diaphragm that is used for HKS GT Pro turbines enables quick boost increasing and stable high boost level.

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.
