Forge Wastegate Actuators

Forge's precision engineered race series approved actuator parts improve performance and boost with fine tuning for improved response and better control.

Being the pioneers of full replacement wastegate actuator technology for internally gated turbochargers, the Forge Motorsport upgraded actuator range is designed to compliment any application making higher than stock boost levels. 

Our quality manufactured actuators can be supplied with different base spring pressure ranges, so the spring tension that best suits their application needs, and the target output can be applied.

With full billet aluminum bodies, laser cut stainless steel brackets, and fast response piston or diaphragm based internals, all actuators have been approved for use by the sanctioning bodies of multiple race series' and are used by numerous shops and teams around the World.

Machined in the UK, hand polished in house, and complete with our limited lifetime guarantee means there's no better choice of actuators anywhere in the world. 





Forge Motorsport were one of the first companies in the world to design and manufacture the billet two-piece replacement aluminium turbo actuator. Originally for the Cosworth, Renault 5 GT turbo, and Lancia Integral turbos, we soon developed the largest and most diverse range of actuator replacements.

When you fit a Forge turbo actuator you will be able to fine tune and manage your specific boost requirements. This will allow for improved response and better control. This product is built with a predetermined actuator spring suitable for, or slightly above factory boost levels.
