GFB WGA – High-Performance Internal Wastegate Actuator

The GFB WGA is a premium internal wastegate actuator, designed to enhance boost control and stability for internally wastegated turbochargers. By utilizing a larger diaphragm area than the stock actuator, the WGA provides superior control over the wastegate flap, preventing exhaust backpressure from prematurely opening it. This results in more consistent, reliable boost levels and improved performance.

Key Features:

• Increased Diaphragm Size – Enhances control over the wastegate flap for more stable boost levels.
• Adjustable Base Boost Pressure – Includes three interchangeable springs, allowing boost settings from 5psi to 24psi.
• Unique Turnbuckle Pre-Load Adjustment – Enables precise fine-tuning for optimal performance.
• Compact & Versatile Design – Features a longer stroke, shorter height, and more adjustment than competitors.
• Direct Bolt-On for EVO X (Part #7303) – Pre-installed with 10psi and 7psi springs for a base pressure of 17psi, with an additional 5psi spring included for further tuning.

Upgrade to the GFB WGA for greater boost stability, improved response, and superior control over your EVO X’s factory turbo system.
