Forge Motorsport were one of the first company’s 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.

The Turbo Actuator for Ford Focus ST MK2 225pk is a high-performance replacement part designed by Forge Motorsport. It is manufactured from 6026 grade aluminium, making it durable and long-lasting. This turbo actuator is vehicle-specific and turbo-specific, ensuring a perfect fit and optimal performance. It is machined and hand polished in the UK, guaranteeing superior quality.

One of the standout features of this product is the choice of spring pressures to suit your car. This allows you to fine-tune and manage your specific boost requirements, resulting in improved response and better control. The actuator is built with a predetermined actuator spring suitable for factory boost levels, but can be assembled with a stronger spring upon request for tuned vehicles. It also features a Nomex reinforced flurosilicone diaphragm, laser-cut stainless steel bracket, and comes with a lifetime warranty.

The Turbo Actuator for Ford Focus ST is a fantastic upgrade for your vehicle. It is easy to set up and install, providing an instant improvement in performance. You don’t even need to remap your car to experience the difference.

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. The actuator can be assembled with a stronger spring upon request for tuned vehicles, and where a higher boost level is required. Please contact us directly concerning this process. It is designed and built with the intention of increasing the boost output of a turbocharged system. We cannot guarantee compatibility with all applications, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine-management-system of the given vehicle at the time of installation, whether that system is factory or aftermarket

Diaphragm sealed internals are the default selection for this actuator product but customers now have the option of piston sealed internals. Unique to Forge Motorsport, this innovation offers equal performance to the diaphragm type and low maintenance due to the hard wearing nature of piston sealed valve internals.

Forge Motorsport nor any of its authorised distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of allowing for the desired level of adjustment. While Forge Motorsport is happy to supply you with an actuator capable of holding boost beyond that of your factory unit we are in no way capable of knowing nor suggesting that your vehicle’s engine or related systems are capable of supporting or surviving the stresses of such elevated boost pressure.

In The Box:

This actuator is built with a stock spring as standard. If you require the FMPACTUN spring tuning kit seen in the associated products below, you will need to select the Diaphragm Type 2, 049 option.

All actuator rods are manufactured from 303 grade stainless steel.

Please note that the quoted spring pressure against the various colour codes relates to the mechanical aspect only, applicable to earlier turbocharged engines that are not ECU/solenoid regulated.

However, modern ECU/solenoid engines do not require the target boost pressure to be matched pound for pound by the quoted mechanical specification of the springs we offer. Please take advice from an appropriately qualified tuner if you are unsure of the correct spring application for your model and the planned level of tuning.
