GT II WASTEGATE

[GT II WASTEGATE]

HKS new 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 forφ60 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.


φ60 VALVE

  • employed φ60 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.

φ50 VALVE

  • employed φ50 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.

Setting for supercharging presuure

φ60 VALVE

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)

φ50 VALVE

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)


  • New arrival has small in size and lightweight but 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.
  • employed existing V band. Can install to the exhaust manifold.
  • The spring change work will be more efficient by using attached SST.

GT WASTEGATE ADAPTER

[GT WASTEGATE ADAPTER]

HKS is introducing new GT(II) wastegate which has employed V band that has more installation angle flexibility for one-off production. With the GT wastegate adapter, it's easy to install to your current exhaust manifold. And it can be used for some other maker's manifold, too.
