With a larger diaphragm than the OEM actuator, the WGA has more “control authority” over the wastegate flap. This makes it harder for exhaust backpressure to blow the wastegate open during spool up and at high RPM, two areas of the boost curve where the factory actuator can be overwhelmed. This benefit is particularly useful with Subaru’s factory “2-port” boost control system, which cannot effectively shut off pressure to the wastegate during spool up.\u003cbr\u003e\u003cbr\u003eSupplied with 3 springs and a unique turnbuckle pre-load adjustment, the base boost pressure can be configured and adjusted from 5psi to 24psi for the best possible boost control.\u003cbr\u003e\u003cbr\u003eThe WGA features a longer stroke, shorter height, and more adjustment than its rivals.\u003cbr\u003e\u003cbr\u003eWGA part # 7305 is designed for Subaru WRX STi models from MY99-21, and will also fit most single-scroll IHI VF turbos. The 5psi and 10psi springs are installed for a base pressure of 15psi, and the 7psi spring is included in the packaging for further tuning options.\u003cbr\u003e\u003cbr\u003ePlease note that whilst this is a “bolt-on” product, it should be considered a tuning tool as it WILL increase boost pressure and therefore TUNING IS REQUIRED.\u003c\/p\u003e\u003ch2 style=\"text-align:center;\"\u003eMORE ABOUT THIS RANGE\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhen it comes to external wastegates, some things you want big, others you want small – like big flow, small size, right?\u003c\/strong\u003e\u003cbr\u003eGFB offers a range that are among the most compact external wastegates in their class, being shorter in height than their closest rivals without sacrificing flow.\u003cbr\u003e\u003cbr\u003eAll GFB wastegates feature an investment cast body made from 253MA chromium-nickel stainless steel, a CNC machined billet stainless valve, and all stainless steel weld-on fittings and hardware, whilst the diaphragm is nomex-reinforced silicone.
