Forge Motorsport Billet Turbo Actuator for Audi A4 and Volkswagon Passat 1.8T Engines
This Forge Motorsport billet two-piece replacement aluminium turbo actuator is specifically designed for the Audi A4 and Volkswagon Passat 1.8T engines that are longitudinally mounted. It is manufactured from 6026 grade aluminium and is vehicle specific, turbo specific, and built to order. The actuator is machined and hand polished in the UK and comes with a choice of spring pressures to suit your car. It also features nomex reinforced flurosilicone diaphragms and laser cut stainless steel brackets (where applicable).
When you fit a Forge turbo actuator, you will be able to fine tune and manage your specific boost requirements, allowing for improved response and better control. The actuator is built with a predetermined actuator spring suitable for, or slightly above factory boost levels, and can be assembled with a stronger spring upon request for tuned vehicles. It is designed and built with the intention of increasing the boost output of a turbocharged system.
Diaphragm sealed internals are the default selection for this actuator product, but customers now have the option of piston sealed internals, offering 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 green coded spring as standard. If you require the FMPACTUN spring tuning kit, fitting of the part is available at our performance workshop at Progressive Parts.
