The GenV WG45 HyperGate45 External Wastegate is a Motorsport proven, cost effective external wastegate – The highest flowing gate of its kind. The GenV provides extensive user configurability, world leading extended thermal performance, fatigue resistance and best in class flow performance for optimum control and longevity.

The GenV External Wastegate from Turbosmart was a ground up rework of a classic and the only feature that rolled over from the Gen4 range was the mounting orientation. CFD optimized and validated in-house for maximum flow and thermal management, the GenV range has more features, options and performance than any other gate like it.

A direct fit upgrade to all Gen4 Turbosmart wastegates and feature our unique collar-locking system, variable actuator cap and base for easy, 360 degree optional routing of reference hoses, strap-type V-band clamps, optional liquid-cooling provision, 1/8″ NPT reference ports and are provided with the full range of available springs.


Do I need to use the liquid cooling ports?

No. It is purely an option for extreme applications where there is limited air flow around the wastegate.

What makes it so thermally advanced?

There are several features, some easily overlooked or hidden. Starting with the valve, there are advanced designed features that ensure thermal dissipation. Thermal transfer was reduced with the use of ceramic spacers either side of the vale guide and huge amount of CFD performed to ensure the most efficient movement of exhaust energy, which also equates to flow.

Can I rotate the top housing?

Yes. The modular design of the Gen-V Range of External Wastegates means you can rotate the actuator housing 360 degrees, for virtually unlimited reference hose routing options.

Will a Gen-V version fit where my 4th Generation Turbosmart Wastegate fit?

 Yes. We made sure the inlet and outlets fitting orientation matched the previous gates for that exact reason. Literally 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. You also need to observe the instructions and apply pressure to the top cap before you can remove the collar – This is part of the design & an important anti-vibration measure.

What size are the reference fittings?

Both the boost control reference ports and the (Optional) liquid cooling ports are 1/8NPT. We have a range of AN adapters and high temp push-lock fittings available in the Spares and Accessories Tab.
