Choosing the Right Turbosmart Wastegate


What Do Wastegates & IWGs Do?

What Do Wastegates & IWGs Do?

The Wastegate is responsible for controlling the flow of exhaust gas from the engine to the turbocharger. By controlling the flow of exhaust gas to the turbine in the turbocharger, the wastegate directly impacts the amount of boost pressure provided by the turbocharger to the engine. As such, the wastegate needs to be correctly sized for the engine and turbocharger to ensure correct boost pressure is delivered to the engine as required.

There are two main types of wastegates; Internal and External. Internal or external refers to whether the wastegate sits on the inside or the outside of the turbo housing.

Internal Wastegate Actuators

Internal wastegate actuators have the wastegate valve built into the turbine housing. Turbosmart’s range of Internal Wastegate Actuators have been engineered using premium quality materials that can withstand high stress and extreme operating temperatures over long periods of time.

Turbosmart Internal Wastegate Actuators are highly adjustable, come with a wide variety of springs that can be set from 3-26 PSI and feature a locking system that allows for fast and reliable springs changes as required. As such, Turbosmart internal wastegate actuators are ideal for performance oriented drivers who require superior boost control.

Vehicle Specific Actuators

Turbosmart vehicle specific wastegate actuators have been designed to provide better turbo response and greater sensitivity when managing boost pressures. Specifically designed to suit popular models across a range of makes including Ford, Mazda, Mitsubishi, Nissan, Porsche, Renault, Subaru and Volkswagen Auto Group vehicles.

  • Direct bolt on replacement
  • Easy to install- no special tools or fabrication required
  • 3-26 PSI adjustable pressure
  • Ideal for lightly modified and tuned vehicles

Turbo Specific Actuators

Turbo Specific Actuators have been designed to provide better turbo response and greater sensitivity when managing boost pressures. Specifically designed for applications where the standard turbo has been upgraded to a larger unit, the actuator is easy to install and requires no special tools or fabrication.

  • Garrett and Borg Warner specific applications
  • Greater turbo response for reduced lag and improved acceleration
  • Easy to install- No special tools required
  • Consistent performance and boost delivery

Universal Fit Actuators

Turbosmart Universal Fit Actuators have been engineered to provide better turbo response and greater sensitivity when managing boost pressures. Universal fit actuators have been designed to fit most factory or aftermarket turbochargers with an internal wastegate.

  • Greater turbo response for reduced turbo lag and improved acceleration
  • Easy to install- No special tools required
  • Consistent performance and boost delivery
  • Ideal for tuned and modified turbocharged vehicles

External Wastegate Actuators

One of the most common reasons for investing in an external wastegate is fitting an aftermarket turbocharger to your vehicle and, consequently, dramatically increasing the power output of your engine. Strongly recommended for engines producing over 400hp, Turbosmart external wastegate actuators feature bigger inlet and outlet ports, higher pressure springs and bigger actuator diaphragms to effectively control high boost pressure.

  • Specifically designed for turbocharged engines producing 400hp+
  • Suitable for street performance and race vehicles
  • Superior flow path and high temperature resistance
  • Consistent boost delivery
  • Ideal for large frame turbochargers not equipped with internal wastegate systems
  • Designed using the latest technology
