Overview

The WGA is a high-performance internal wastegate actuator designed to improve boost control on internally wastegated turbos. It utilizes a significantly larger diaphragm area than the OEM actuator, providing greater control authority over the wastegate flap. This results in more stable and reliable boost control by preventing exhaust backpressure from easily overriding the flap position. It is supplied with three springs and features a unique turnbuckle pre-load adjustment, allowing the base boost pressure to be configured and adjusted from 5psi to 24psi for optimal boost control. The WGA boasts a longer stroke, shorter height, and more adjustment compared to its rivals. WGA part #7301 is specifically designed to bolt onto EVO 4-8 models with the factory turbo. The 10psi and 7psi springs are pre-installed for a base pressure of 17psi, with an additional 5psi spring included for further tuning options. It's important to note that while 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.

Part #: 7301

Massive Performance, Compact Size.a Industry-first diaphragm design - the WGAa (TM)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. Ita (TM)s like telling your turbo what to do instead of pleading with it!a Longest stroke a 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.a Unique pivoting rod guide a 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.a No unnecessary bulk a 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 thata (TM)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. Thata (TM)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 high performance internal wastegate actuator. The WGA replaces the factory turboa (TM)s actuator, offering a larger diaphragm and adjustable base spring pressures ranging from 5-22psi to get the most out of your turbo.
