Custom Billet Adjustable Internal Wastegate Actuator - Bespoke Configuration

Under a high boost level, the stock actuator's weak spring allows the wastegate to blow open, limiting midrange torque. Bleed orifices just make it worse. The problem can be solved by replacing the boost actuator. Kinugawa Billet actuators allow more precise and more stable boost control for internally wastegated turbos. Kinugawa actuators hold the wastegate closed for quicker boost, then controls the opening to maintain peak boost for superior acceleration and mid-range towing or pulling power.Kinugawa actuators are available in both single and dual port configurations and is now also available in a big-head design for additional benefits over the standard actuators.
