This keeps the overall size of the WGA down whilst giving it more control authority over the wastegate flap, resulting in better boost control. It’s like telling your turbo what to do instead of pleading with it!\n\n•\tLongest stroke – with 18mm of rod travel, the WGA is suitable for controlling the largest of internal wastegates, or the extra travel can be used to further increase boost pressure without having to change springs.\n\n•\tUnique pivoting rod guide – machined from PEEK (an extremely high-performance engineering polymer), the encapsulated spherical rod guide takes up significantly less height in the actuator body than other designs, whilst offering low friction and superior wear resistance.\n\n•\tNo unnecessary bulk – sounds obvious, but attention to detail in the design means the WGA is the shortest actuator on the market.\nMore Adjustable, More Easily. \nSetting 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!\nWe 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. \nThat’s why we added another industry first - turnbuckle adjustment. The long stroke of the WGA means more adjustment range for the spring pre-load, so you can fine-tune your base boost pressure in a matter of minutes without swapping springs or removing the actuator. \n\nAvailable in bolt-on or universal kits - Check the GFB website for details.\nBolt on high performance internal wastegate actuator. The WGA replaces the factory turbo’s actuator, offering a larger diaphragm and adjustable base spring pressures ranging from 5-22psi to get the most out of your turbo.\nSubaru: Impreza 02 - 07 WRX\n\u003cul\u003e\n  \u003cli\u003eWGA Benefits (compared to a factory-fitted actuator):\n•\tFaster spool up\n•\tLess boost taper at high RPM\n•\tMore stable boost control\n•\tCustomizable spring rates\n•\tSupports higher boost pressure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade your Subaru Impreza's turbo performance with the Go Fast Bits GFB TD04 Internal Wastegate Actuator. Designed to replace the factory actuator, this high-performance component features a larger silicone\/Nomex diaphragm with an innovative bead retention system that maximizes effective area while maintaining a compact size. This design offers better control over boost regulation, translating into faster spool times, reduced boost taper at high RPM, and more stable boost control across your engine's operating range. The result is a more responsive turbo system that supports higher boost pressures for improved power delivery.\u003c\/p\u003e\u003cp\u003eThe GFB TD04 actuator boasts an 18mm stroke, allowing for precise control over large internal wastegates or enabling increased boost pressure without spring changes. Its unique pivoting rod guide, machined from durable PEEK polymer, reduces height and friction while enhancing wear resistance, ensuring long-term reliability. Despite its robust features, the actuator maintains a minimal footprint, making it the shortest unit available on the market, ideal for tight engine bays.\u003c\/p\u003e\u003cp\u003eAdjustability is a key feature of the GFB TD04 actuator. It includes a turnbuckle for quick and easy spring preload adjustments, allowing fine-tuning of boost pressure from 5 to 22 psi without removing or swapping springs. The package includes three stainless steel springs, offering versatile options for different boost targets. Available in bolt-on or universal kits, installation is straightforward, and the actuator can be configured to optimize spool-up, boost stability, and overall performance. Suitable for Subaru Impreza models from 2002 to 2007, this actuator supports higher boost levels and delivers a more consistent and customizable turbocharging experience, making it an excellent upgrade for enthusiasts seeking peak performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eIndustry-first silicone\/Nomex diaphragm with bead retention design for maximum effective area\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e18mm stroke for controlling large internal wastegates or increasing boost pressure\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePivoting rod guide machined from high-performance PEEK polymer for low friction and wear resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompact design, the shortest actuator on the market, ideal for tight engine bays\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTurnbuckle adjustment for quick and precise boost pressure fine-tuning\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes three stainless steel springs for versatile boost settings from 5 to 22 psi\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFits Subaru Impreza models from 2002 to 2007, replacing factory turbo actuator\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports higher boost pressures, faster spool-up, and more stable boost control\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2002 Subaru Impreza WRX\u003cbr\u003e\n2003 Subaru Impreza WRX\u003cbr\u003e\n2004 Subaru Impreza WRX\u003cbr\u003e\n2005 Subaru Impreza WRX\u003cbr\u003e\n2006 Subaru Impreza WRX\u003cbr\u003e\n2007 Subaru Impreza WRX\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbdoy\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: true\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: t\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbdoy\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Go Fast Bits","offers":[{"title":"Default Title","offer_id":53602452406545,"sku":"7304","price":209.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/3830\/0689\/files\/91fb86c29752c1fad1d9a3ce337ea543.jpg?v=1779943124","url":"https:\/\/shoprenegade.com\/products\/go-fast-bits-gfb-mitsubishi-td04-internal-wastegate-actuator-part-number-7304-for-subaru-impreza","provider":"Renegade Speed by Renegade Racing \u0026 Performance","version":"1.0","type":"link"}
