Product Description

The Go Fast Bits 7300 WGA Internal Wastegate Actuator is a precision performance upgrade engineered for the turbocharged Mitsubishi Lancer Ralliart (2008-2015) equipped with the 4B11T engine. Designed to replace the factory wastegate actuator, the GFB WGA features a significantly larger diaphragm and adjustable springs, giving enthusiasts greater authority over wastegate control for more consistent and stable boost delivery. This results in improved throttle response, reduced boost taper at higher RPM, and an overall more satisfying turbo experience.

Supplied with multiple springs and a unique turnbuckle pre-load adjuster, the actuator allows base boost pressure adjustment from approximately 5 psi up to around 24 psi depending on tuning setup. While the actuator bolts directly to the factory turbo wastegate flange, it should be considered a tuning component - professional ECU tuning is recommended after installation to safely optimize performance and prevent engine damage. Built with high-quality materials and designed for motorsport durability, the GFB 7300 is ideal for enthusiasts seeking reliable, adjustable boost control on their Mitsubishi Lancer Ralliart.
