The factory actuator’s weak diaphragm spring allows the wastegate to blow open prematurely under high boost — robbing mid-range torque and capping peak power. Kinugawa’s dual port design holds the wastegate closed longer, delivering quicker spool, sharper throttle response, and sustained peak boost for superior acceleration and mid-range pulling power.\u003c\/p\u003e\n\u003cp\u003eThis kit ships with a \u003cstrong\u003e1.0 bar (14.7 psi) spring pre-fitted\u003c\/strong\u003e on the actuator head, plus a full set of 6 additional springs and 4 straight rods in four lengths — giving you everything needed to dial in the exact boost pressure and rod geometry for your specific turbo application.\u003c\/p\u003e\n\u003ch3\u003eCompatible Application\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal fit — compatible with internal wastegate turbochargers across multiple platforms\u003c\/li\u003e\n\u003cli\u003eDual port type; can also be run as single port (leave lower port vented to atmosphere)\u003c\/li\u003e\n\u003cli\u003eSuitable for street, track, and towing\/pulling builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Performance Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHolds the wastegate valve seated longer — higher peak boost achieved sooner\u003c\/li\u003e\n\u003cli\u003eProduces strong torque from idle through the full RPM range\u003c\/li\u003e\n\u003cli\u003eCrisp, controlled boost response — eliminates boost creep and mid-range sag\u003c\/li\u003e\n\u003cli\u003eBidirectional diaphragm control for more precise boost management vs. single port\u003c\/li\u003e\n\u003cli\u003eMultiple rod lengths and spring pressures included for universal fitment flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSingle Port vs. Dual Port — What’s the Difference?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSingle Port Actuators\u003c\/strong\u003e\u003cbr\u003eBoost reference is supplied to one side of the diaphragm. The wastegate opens in one direction; spring pressure alone handles the return stroke and holds the wastegate closed. Best suited for basic boost control via a manual boost controller (MBC) or electronic boost controller (EBC). Simple plumbing, straightforward setup — ideal for street and mild performance builds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual Port Actuators\u003c\/strong\u003e\u003cbr\u003eBoost reference is supplied to both sides of the diaphragm, enabling bidirectional control of the wastegate — both opening and closing. Spring pressure is pneumatically assisted on the return stroke, allowing a softer spring to achieve the same or higher boost targets with greater precision. Recommended for high-boost applications, high exhaust backpressure environments, or oversized wastegates. Best used with an EBC for maximum tunability.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eTech Tip: Dual port actuators can also be run as a traditional single port — simply leave the lower actuator port vented to atmosphere.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eSpring Pressure Options \u0026amp; Setup Reference\u003c\/h3\u003e\n\u003cp\u003eSix spring pressure options are included: \u003cstrong\u003e0.5 bar, 0.8 bar, 1.0 bar, 1.2 bar, 1.5 bar, and 1.7 bar\u003c\/strong\u003e.
