GFB WGA: High-Performance Internal Wastegate Actuator

Superior Boost Control, More Power, Better Reliability

The GFB WGA is a high-performance internal wastegate actuator, engineered to provide more stable and reliable boost control on internally wastegated turbos. By utilizing a larger diaphragm area than stock actuators, the WGA offers greater control authority over the wastegate flap, reducing the chances of exhaust backpressure overriding the flap position. The result? More precise boost control and improved turbo performance.

Key Features:

• More Control, Less Boost Creep – Larger diaphragm area prevents exhaust pressure from pushing the wastegate open too soon, allowing for tighter boost control.
• Customizable Boost Settings – Comes with three interchangeable springs and an adjustable turnbuckle pre-load, allowing base boost adjustment from 5psi to 24psi.
• Compact & Versatile Design – Features a longer stroke, shorter height, and more adjustability than competing actuators.
• Direct Bolt-On Fitment – The WGA #7304 is designed to fit Subaru WRX (MY97-07) with the factory TD04 turbo.
• Pre-Configured for Easy Installation – Comes with 5psi and 7psi springs pre-installed (for a 12psi base pressure) plus an additional 10psi spring for further tuning options.

Optimize Your Boost Control

Choosing the right wastegate spring is crucial for maximizing performance. The WGA’s customizable spring setup ensures that you can fine-tune your boost response for the best possible power delivery and reliability.
