WGA Wastegate Actuator EVO 4-8 [7301]

GFB WGA: High-Performance Internal Wastegate Actuator

Take Control of Your Boost with Precision and Reliability

The GFB WGA is a high-performance internal wastegate actuator, engineered to provide greater boost control and stability for internally wastegated turbochargers. Featuring a significantly larger diaphragm area than OEM actuators, the WGA ensures better authority over the wastegate flap, preventing exhaust backpressure from forcing it open prematurely. The result? More stable boost levels, improved turbo response, and enhanced overall performance.

Key Features:

• Optimized Boost Control – Larger diaphragm ensures more stable and accurate boost management.
• Adjustable Base Pressure – Comes with three interchangeable springs and an adjustable turnbuckle pre-load, allowing for a boost range from 5psi to 24psi.
• Compact & Versatile Design – Offers a longer stroke, shorter height, and more adjustability than other actuators.
• Direct Bolt-On Fitment – WGA #7301 is designed specifically for Mitsubishi EVO 4-8 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 fine-tuning.

Fine-Tune Your Boost for Maximum Performance

The WGA’s customizable spring setup allows precise boost adjustments, ensuring optimal turbo response and reliability.

Upgrade your EVO 4-8 with the GFB WGA for superior boost control, sharper throttle response, and increased turbo efficiency!
