Turbosmart isn’t just another name in the performance aftermarket, it’s a brand built on innovation, motorsport pedigree, and a relentless pursuit of boost control perfection. Founded in Australia in 1997, Turbosmart has grown into a global leader in turbocharger accessories, trusted by tuners, racers, and OEMs alike. Whether you're chasing lap times or refining your daily driver, Turbosmart’s products are engineered to deliver sharper response, greater reliability, and total control.
Let’s dive into two of their most popular product categories: Diverter Valves and Turbo Actuators, what they do, why they matter, and how to choose the right one.

What Is a Diverter Valve — and Why Upgrade?
A diverter valve (DV) is a key component in turbocharged engines. When you lift off the throttle, the turbo is still spinning and producing boost, but that pressurised air needs somewhere to go. The diverter valve redirects it back into the intake system, preventing compressor surge and maintaining drivability.
Why Upgrade?
Factory diverter valves are often made from plastic and designed with cost in mind, not performance. They can leak under high boost, respond slowly, or fail entirely. Upgrading to a Turbosmart DV means:
- Faster throttle response
- Improved boost retention
- Greater reliability under load
- Enhanced sound (if desired)

Turbosmart Diverter Valve Options
Turbosmart offers several DV styles to suit different driving goals and sound preferences:
|
Model |
Type |
Benefits |
Best For |
|---|---|---|---|
|
Kompact EM Plumb Back |
Fully recirculating |
Quiet operation, OEM-like integration, improved sealing |
Daily drivers, stealth builds |
|
Kompact EM Dual Port |
Recirculating + atmospheric |

Enthusiasts wanting a bit of turbo whoosh |
|
Kompact EM VAG V2 |
Plug-and-play for VW/Audi |
Motorsport-grade billet construction, fast response |
VAG owners seeking direct OEM replacement |
|
Kompact EM VR1 |
Universal fitment |
Boost-balance tech, high-temp solenoid, billet body |
Custom builds, high-performance applications |
Key Tech Highlights:
- Boost-Balance Valve Design: The more boost you run, the tighter the seal.
- Positive Seal O-Ring: Ensures zero leaks and maximum pressure retention.
- Billet Aluminium Construction: Durable, heat-resistant, and race-proven.
Whether you want subtle performance or full-on turbo theatrics, Turbosmart has a DV to match.
What Is a Turbo Actuator — and Why It Matters
A turbo actuator (also known as a wastegate actuator) controls the turbocharger’s boost pressure by opening and closing the wastegate. It’s essentially the gatekeeper of your turbo’s output.
Why Upgrade?
Stock actuators can struggle to hold boost at higher pressures or respond quickly enough for aggressive tuning. Turbosmart’s actuators offer:
- Greater boost control accuracy
- Faster response times
- Wider tuning windows
- Durability under extreme conditions

Turbosmart Turbo Actuator Range
Turbosmart’s Internal Wastegate Actuators (IWG) are built from billet aluminium and feature stainless steel rods, proprietary diaphragms, and a clever locking collar for easy spring changes.
