HKS GT wastegate has big engine displacement and high supercharging pressure for smaller and lighter design. With the smaller design, there is more room for layout. And the installation with the V band makes it easier for maintenance. 2 types of valve diameter of φ60, φ50 setting can have the stable control over boost for the size of the turbocharger. There are 4 wastegate spring for φ60 and 3 for φ50(2 are already loaded for both products) attached, therefore, it's possible to change from wide range of boost pressure setting.
