Turbosmart External Wastegate GenV Hypergate45 FAQ's


  • Do I need to use the liquid cooling ports?

No. however, it is purely an option for extreme applications where there is limited airflow around the wastegate.

  • Can I rotate the top housing?

The modular design of the GenV Range of External Wastegates means you can rotate the actuator housing 360 degrees. As a result, virtually unlimited hose routing options.

  • Will a GenV version fit where my Gen4 Turbosmart Wastegate fit?

We made sure the inlet and outlets fitting orientation matched the previous gates for that exact reason. As a result, the only thing in common between the previous design and this one is the mounting orientation.

  • How do I change the spring(s)?

You will need the locking collar tool as supplied in the box. Most importantly, you also need to observe the instructions. Secondly, apply pressure to the top cap before you can remove the collar. This is part of the design. Moreover, an important anti-vibration measure.

  • What size are the reference fittings?
