Go Fast Bits GFB Mitsubishi EVO 9 Internal Wastegate Actuator Part #7302

Massive Performance, Compact Size. • Industry-first diaphragm design - the WGA’s Silicone/Nomex diaphragm uses a new bead retention design that achieves the largest effective area with the smallest possible outside diameter. 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! • Longest 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. • Unique 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. • No unnecessary bulk – sounds obvious, but attention to detail in the design means the WGA is the shortest actuator on the market. More Adjustable, More Easily. Setting 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! We 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. That’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. Available in bolt-on or universal kits - Check the GFB website for details. Bolt on internal wastegate actuator for Mitsubishi EVO 9 models. 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. Mitsubishi: Lancer 05 - 06 Evolution

• WGA Benefits (compared to a factory-fitted actuator): • Faster spool up • Less boost taper at high RPM • More stable boost control • Customizable spring rates • Supports higher boost pressure

Upgrade your Mitsubishi Lancer Evolution 2005-2006 with the GFB Mitsubishi EVO 9 Internal Wastegate Actuator from Go Fast Bits. This high-performance actuator features an industry-first silicone/Nomex diaphragm with a novel bead retention design, providing the largest effective area within a compact size. This design enhances control authority over the wastegate flap, delivering more precise boost regulation and improving overall turbo responsiveness. Its innovative construction allows for better boost control, making your turbocharged engine more predictable and responsive under various driving conditions.
The actuator boasts an 18mm stroke, enabling it to handle the largest internal wastegates or extend boost pressure with ease. The long travel capability allows fine-tuning of boost levels without the need to swap springs, simplifying the adjustment process. The unique pivoting rod guide, machined from durable PEEK polymer, minimizes height within the actuator body and offers low friction and exceptional wear resistance, ensuring reliable performance over time.
Designed with minimal bulk, the GFB WGA is the shortest actuator available, allowing for seamless installation without unnecessary space constraints. Its adjustable design includes three stainless steel springs, offering a wide range from 5psi to 22psi, and features industry-first turnbuckle adjustment for quick, precise spring preload tuning. This makes setting your ideal boost pressure faster and more convenient than ever, without needing to change springs or disassemble the actuator.
Compatible with bolt-on or universal kits, this actuator replaces the factory component on your Mitsubishi EVO 9, providing benefits like faster spool-up, reduced boost taper at high RPM, more stable boost control, and support for higher boost pressures. Whether you want to maximize performance or fine-tune your boost levels, the GFB Mitsubishi EVO 9 Internal Wastegate Actuator offers a reliable, adjustable solution to meet your turbocharging needs.
