These turbo actuators have been developed specifically for BMW’s  N54 twin turbo motor, as found in the BMW 135,335 and 535 models,  Whilst similar to the actuators as used from the factory , these have the added benefit of :

  • The entire valve assembly is precision CNC machined from T6-6061 billet aluminum alloy on our very own Mazak CNC milling machines. 
  • The actuators are fully tunable by way of proprietary interchangeable springs
  • Suitable as a direct replacement replacement for a stock car or one that is heavily modified.
  • They are capable of handling an infinitely wider range of boost pressure, more reliably, than the OEM actuators.

This product is built with a predetermined actuator spring suitable for at, or slightly above factory boost levels. The actuator can be assembled with a stiffer spring upon request. Please contact us directly concerning this process

Whilst these actuators are 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. Forge Motorsport nor any of it’s 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.
