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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\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.\u003c\/p\u003e\n\u003cp\u003eRead on for more technical information on wastegate springs, and how the correct\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/gfb.com.au\/tech\/tech-articles\/how-to-choose-wastegate-springs\/\"\u003espring selection\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003ecan improve performance.\u003c\/p\u003e\n\u003cp\u003eThe WGA features a longer stroke, shorter height, and more adjustment than its rivals.\u003c\/p\u003e\n\u003cp\u003eWGA part # 7305 is designed to bolt on to 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eMORE ADJUSTABLE, MORE EASILY.\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003eSetting the base spring pressure correctly for your application can have significant performance benefits, so we made sure the WGA offers the best adjustability on the market!\u003c\/p\u003e\n\u003cp\u003eWe supply 3 stainless steel springs that can be used in any combination ranging from 5psi to 22psi, but that’s only the beginning. Whilst other brands may offer more spring options (sold separately), changing springs to fine-tune boost pressure is time consuming and quite frankly, a pain in the butt.\u003c\/p\u003e\n\u003cp\u003eThat’s why we added another industry-first: turnbuckle adjustment. Because the WGA was designed with a long stroke, it is possible to use some of that extra stroke length to fine-tune the base boost pressure in a matter of minutes without swapping\u003cbr\u003esprings or removing the actuator.\u003c\/p\u003e\n\u003cp\u003eAs an added benefit, the turnbuckle makes swapping springs so easy that it can often be done without removing the actuator from the car!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: that whilst this is a physical “bolt-on” product, it should be considered a tuning tool as it WILL increase boost pressure and therefore TUNING IS REQUIRED.\u003c\/strong\u003e\u003c\/p\u003e","brand":"GFB","offers":[{"title":"Default Title","offer_id":50628683759919,"sku":"7305","price":257.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0848\/3903\/9279\/files\/7305_1-1-scaled.jpg?v=1729813617","url":"https:\/\/www.prospeedracing.com.au\/products\/gfb-wga-internal-wastegate-actuator-7305","provider":"Pro Speed Racing","version":"1.0","type":"link"}
