Forge Blow Off Valve for Vauxhall Calibra Turbo

Forge Motorsport was one of the world's first manufacturers to design two-piece aluminum dump valves. Originally designed for Cosworth, Renault 5 GT Turbo, and Lancia Integral Turbo, they soon developed a wide range. By installing a Forge actuator, you can achieve full and precise adjustment, and manage specific turbo pressure needs. This product offers improved turbo response and control. It is manufactured with a standard spring suitable for pressures slightly above those of the factory turbo.

The blow-off valve has been designed and manufactured to increase turbo pressure. We cannot guarantee compatibility with all models, nor the ability to increase turbo pressure above the level defined by the vehicle's engine programming at the time of installation, whether original or modified.

The diaphragm setup is the default, but a piston setup is also available. Exclusive to Forge Motorsport, this innovation offers similar performance to the diaphragm, as well as less demanding maintenance due to the piston's robustness. Forge and its distributors are not responsible for damages caused by the installation or adjustment of this product in a vehicle whose programming, whether standard or modified, does not allow for an additional level of adjustment.
