HKS heavy duty actuators can enable increased boost pressure by altering the length of the actuator rod. Obtain increased engine horsepower just by installing a reasonably priced actuator upgrade kit to the turbine kit.
Features
Power
To obtain extra horsepower in a factory set up with increased boost, just replace the factory actuator with the HKS actuator kit onto the factory turbine kit, or with an upgraded HKS turbine kit. This will result in an instant increase in engine power.
Cost
To reduce cost, the factory turbine kit can be used, and still obtain an increase in engine horsepower.
Boost pressure adjusted
Boost pressure can be altered by expanding or retracting the actuator rod.

HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
