GFB Mitsubishi TD04 Internal Wastegate Actuator

The GFB Mitsubishi TD04 Internal Wastegate Actuator is a high-performance boost control component designed for Mitsubishi turbocharged engines. Featuring an industry-first Silicone/Nomex diaphragm with a bead retention design, it offers the largest effective area while maintaining a compact size, resulting in improved control authority over the wastegate flap. With an 18mm rod travel, it is suitable for controlling large internal wastegates or increasing boost pressure without spring changes. The unique pivoting rod guide, machined from PEEK, provides low friction and superior wear resistance, while the overall design ensures the shortest actuator on the market. Its adjustable turnbuckle and three stainless steel springs (ranging from 5psi to 22psi) allow precise, quick boost tuning without spring swapping, enhancing performance and reliability.

This actuator is compatible with Mitsubishi turbo systems utilizing the TD04 internal wastegate, suitable for various models and engine configurations. It serves as an upgrade or replacement for OEM components, offering improved boost control for street and track applications. Installation is straightforward, with options for bolt-on or universal kits. The design caters to enthusiasts seeking precise boost management, whether for daily driving, racing, or tuning purposes. The kit includes the actuator and necessary components for optimal fitment and performance enhancement.
