HKS GTII Waste Gate D50/D60 Valve (14005-AK001)

The HKS GT wastegate is designed for large engine displacement and high supercharging pressure, featuring a compact and lightweight design that provides more flexibility for layout. Its smaller size, combined with V-band installation, simplifies maintenance. Available in two valve diameters, D60 and D50, these wastegates offer stable boost control for various turbocharger sizes. Both models come with pre-installed springs—four for the D60 and three for the D50—allowing for easy adjustment across a wide range of boost pressure settings.

Vehicle Fitment:
Universal

D60 Valve Details:
D60 valve, same as the GT wastegate but smaller and lightweight that has the about the same lift power and flow characteristics. We have made 2/3 of lightweight of 2,246g to 1,509g compare to GT wastegate.

• 1.58.8～98.1kPa (0.6～1.0kgf/cm2)
• 2.88.3～127.5kPa (0.9～1.3kgf/cm2)
• 3.127.5～166.7kPa (1.3～1.7kgf/cm2)
• 4.166.7～205.9kPa (1.7～2.1kgf/cm2)

D50 Valve Details:
D50 valve that is same as the SPL(racing) wastegate and we made them lightweight.We have made 3/4 of lightweight of 1,890g to 1,443g compare to SPL(racing) wastegate.

• 1.78.5～107.9kPa (0.8～1.1kgf/cm2)
• 2.107.9～137.3kPa (1.1～1.4kgf/cm2)
• 3.137.3～166.7kPa (1.4～1.7kgf/cm2)
• 4.166.7～196.1kPa (1.7～2.0kgf/cm2)

Small in size and lightweight, but it has the same lift amount/flow characteristic as the GT wastegate. The upper case is made of alumite, and housing is stainless cast steel for the beautiful exterior. Adopted G coupling for installation of upper cases and lower case. V band is included to install the exhaust manifold. The spring change work will be more efficient by using attached SST.
