Forge Motorsport Turbo Actuator for Ford Focus RS or STi Models
The Forge Motorsport Turbo Actuator is specifically designed for the Ford Focus RS or STi models. It is available in two versions: one with a straight rod and one with a bent rod. It is important to determine which version you need before ordering.
This billet two-piece replacement aluminium turbo actuator is manufactured from high-quality 6026 grade aluminium. It is vehicle and turbo specific, ensuring a perfect fit and optimal performance. The actuator is machined and hand polished in the UK, guaranteeing excellent craftsmanship.
With a choice of spring pressures, you can customize the actuator to suit your car’s specific needs. The actuator is available with either a piston or diaphragm operation, depending on your preference. It features nomex reinforced flurosilicone diaphragms and laser-cut stainless steel brackets for added durability.
When you install the Forge Motorsport Turbo Actuator, you gain the ability to fine-tune and manage your boost requirements. This allows for improved response and better control. The actuator is designed to increase the boost output of a turbocharged system, but it is important to note that compatibility and boost levels are dependent on the engine management system of your vehicle.
The actuator comes with a stock spring as standard, but you can upgrade to a stronger spring with the FMPACTUN spring tuning kit. Please note that fitting of the part is available at our performance workshop at Progressive Parts.

- 1 x FMACFRS Actuator
