-31 Wastegate Actuator to fit 4wd Sierra RS Cosworth

Motorsport Developments

1x Brand New -31 Rated T3 Fitment Wastegate Actuator.This wastegate actuator is of the type normally found fitted to the 4wd Sierra Rs Cosworths.The -31 actuator has an initial lift pressure of 8psi when used without boost control and is used up to 2 bar with additional boost control such as amal valves, air injectors etc...Don't pay more money for inferior alloy products. This device controls your turbocharger boost pressure and if it fails you can destroy your engine. We have seen inferior alloy products that have had the little securing screws fall out so the unit is no longer airtight. Take care out there. All that shines is not usually gold!Please Note :Most suppliers sell you a normal -31 with shorter shaft length and then have you fit a rough looking extension piece to the end. Why downgrade and fiddle around with two items? Why not just buy the correct length from us in the first place? We are usually cheaper too!

Forge Ford Sierra Cosworth 4 Wheel Drive Adjustable Actuator

Forge

This actuator is designed for the Ford Sierra CosworthForge 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.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 FMACCOS4 Actuator1 x Forge StickerThis actuator is built with a green coded 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 3, 048 option.

Turbosmart IWG75 Ford Sierra Cosworth 14psi

Turbosmart

Turbosmart Upgraded Wastegate Actuators have been developed to provide maximum possible boost response for your factory frame turbocharger. The Turbosmart IWG75 Series of upgraded Actuators benefit from an increased 'Working Ratio' over the factory equipment resulting in improved boost response, throughout the RPM range.This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.Upgrading with the same base pressure as factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning & recalibration is likely required.FeaturesProprietary Silicon Nomex DiaphragmChoice of Springs from 3psi to 26psi (Optional)High Grade Billet Aluminum ConstructionStainless Steel Rods and ClevisTurbosmart Unique Locking Collar SystemThis is a bolt on fitment for the T3 turbocharger as fitted to the Ford Sierra Cosworth 2.0L DOHC Turbo motor.
