PRODUCT DESCRIPTION
These actuators were designed for the Mitsubishi GTO (3000GT) twin-turbo (price per pair). Made from billet aluminum, these Forge adjustable actuators are a two-piece design, which makes them easy to service and maintain. This also allows the rods to be adjusted for individual settings. Stainless steel mounting brackets allow for a standard-fit replacement. This product is built with a default actuator spring for atmospheric or slightly above factory boost pressures. This actuator can be supplied with a stiffer spring on request. Please contact us in this instance. It has been designed and manufactured with the aim of increasing the turbo boost. We cannot guarantee compatibility with all models, or the ability to increase the boost pressure above the level set by the vehicle's engine management programming at the time of installation, whether original or modified programming. Please note: The boost pressure figures stated in the drop-down list above are minimum adjustment figures. If you have any questions, please feel free to contact us. The diaphragm configuration is the default, but customers now have the option of requesting the piston configuration. This innovation is exclusive to Forge Motorsport and offers similar performance to the diaphragm design, as well as easy maintenance due to the strength of the components. Forge Motorsport and its distributors accept no responsibility for any damage caused by the installation or adjustment of this product to a car whose programming, whether standard or modified, does not allow an additional level of adjustment. We are pleased to be able to offer you this Forge Motorsport actuator, but we cannot know or recommend whether the different bodies of your engine will be able to withstand such high pressures. After several requests for a product that will last a lifetime, resist corrosion or simply not tarnish, Forge now offers the ability to order all its piston diverter valve actuators and stainless steel fasteners. This option incurs an additional cost that will be added to your cart. In the box: 2 x FMGTOACT Actuator 1 x Forge Decal These actuators are assembled with a green spring as standard. If you also wish to order the FMPACTUN spring kit, you will need to select diaphragm type 2, option 049.
