The GT Wastegate, which would handle large displacement, high boost situations with relative ease is now available in a lightweight more compact design with all the performance of the previous version. The compact design gives more space and freedom within the engine bay for layout and piping whilst the V band flanges allow for easy fitment and removal for maintenance. Available in 2 valve sizes, 50 and 60mm to suit a wide range of turbochargers. With 4 springs for the 60mm and 3 springs for the 50mm, multiple combinations can be used to acquire the exact boost you're your application
60 Valve
Utilising the same 60mm valve as the GT Wastegate, the same valve lift and flow capacities are maintained whilst making the whole unit more compact.
Weight is reduced from 2,246g in the GT Wastegate down to 1509g
58.8~98.1kPa(0.6~1.0kgf/cm2)
88.3~127.5kPa(0.9~1.3kgf/cm2)
127.5~166.7kPa(1.3~1.7kgf/cm2)
166.7~205.9kPa(1.7~2.1kgf/cm2)
50 Valve
Utilising the same 50mm valve from Special Racing Wastegate, a more compact design has allowed a lightweight unit which does not compromise on performance
Weight is reduced from 1,890g in the Special Racing Wastegate down to 1443g?
78.5~107.9kPa(0.8~1.1kgf/cm2)
107.9~137.3kPa(1.1~1.4kgf/cm2)
137.3~166.7kPa(1.4~1.7kgf/cm2)
166.7~196.1kPa(1.7~2.0kgf/cm2)
Lift amount and flow properties are maintained from previous generation GT Wastegate in a smaller compact lightweight design.
Upper casing is finished in HKS' distinct purple anodising whilst the housing is cast stainless. This combination created an item which is not only functional, but accents the engine bay.
V band flanges used as per previous model to allow use of existing exhaust manifolds.
Spring changes are easy by using included SST

Simple power upgrade
By simply changing the actuator(s) on your stock turbo, power can be increased by raising boost levels.
Affordable Performance
As an easy first step to tuning, actuators can be fitted to boost power without changing the stock turbocharger.
Adjustable Boost
By adjusting the rod of the actuator, Boost can be controlled and set to the users exact specification.
Fitment/usage notes
Increasing boost levels can lead to engine damage or failure if the appropriate fuel management is not in place. For large boost increases, please ensure that you have fuel cut control (FCD or similar) and fuel control method (F-Con or similar)
