Forge Turbo Actuator for Ford Focus ST250 (2012-2018)


A replacement turbo actuator for the Ford Focus ST250.Forge Motorsport were one of the first companys 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.Choice of spring pressures to suit your carManufactured from 6026 grade aluminiumVehicle specificTurbo specificBuilt to orderMachined and hand polished in the UKChoice of piston or diaphragm operation on most actuatorsNomex reinforced flurosilicone diaphragmsLaser cut stainless steel brackets (where applicable)Tuning and service kits availableMade in EnglandLifetime warranty*Please Note:The pressure figures listed in the drop-down menu above are minimum regulated pressure figures. If you are unsure, please don't hesitate to call us on 01452 380999. 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 aftermarketDiaphragm 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:1 x FMACST250 Actuator1 x Forge StickerThis 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.

IWG75 Ford Focus ST 2.0L Ecoboost 7 PSI


Ford Focus ST 2.0L Ecoboost Internal Wastegate Actuator (IWG) provides better turbo response and greater sensitivity when managing boost pressures. Designed as a direct bolt-on replacement for the factory part, the ecoboost IWG is easy to install and requires no special tools or fabrication. Weve taken the proven technology from our WG38, 40 and 45mm External Wastegates and applied it to the Internal Wastegate Actuator.
