GFB WGA: High-Performance Internal Wastegate Actuator

Superior Boost Control for Internally Wastegated Turbos

The GFB WGA is a high-performance internal wastegate actuator designed to deliver more stable and reliable boost control for internally wastegated turbochargers. With a significantly larger diaphragm area than stock actuators, the WGA provides greater control over the wastegate flap, preventing exhaust backpressure from overriding its position. This results in precise boost management, improved turbo response, and enhanced performance.

Key Features:

• Enhanced Boost Stability – Larger diaphragm area prevents boost creep and ensures more accurate boost control.
• Adjustable Boost Pressure – Includes three interchangeable springs and an adjustable turnbuckle pre-load, allowing for base boost settings from 5psi to 24psi.
• Compact & Versatile Design – Longer stroke, shorter height, and greater adjustability than competing actuators.
• Direct Bolt-On Fitment – WGA #7302 is designed specifically for Mitsubishi EVO 9 models with the factory turbo.
• Pre-Configured for Easy Installation – Ships with 10psi and 7psi springs pre-installed (for a 17psi base pressure), with an additional 5psi spring included for further tuning.

Optimized Performance & Tunability

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