Note: When fitting a Forge turbo actuator, you can achieve a full and accurate setup and manage your specific boost pressure needs. This product provides improved response and control of the turbo. It is manufactured with a standard spring suitable for pressures slightly higher than the factory turbo. The wastegate has been designed and manufactured to increase boost pressure. We cannot guarantee compatibility with all models, nor the ability to increase boost pressure beyond the level defined by the vehicle's engine mapping at the time of installation, whether original or modified.
We are pleased to offer you this Forge Motorsport actuator, but we cannot know or recommend whether the various components of your engine will be able to withstand such high pressures.
