The Turbosmart wastegate actuator range has been designed as a stronger, more reliable replacement for OEM parts. Like all Turbosmart parts, billet construction means they are stronger and more durable than a stock actuator, while Turbosmart’s focus on performance means boost comes on faster and holds on longer.

- Stable boost control
- Improved boost response
- Flatter boost curve in the top end
- Interchangeable springs for a great range of boost levels

What is in the box?
  • Everything you will need to get up and going with a Borg Warner EFR Turbocharger. That is, our swivel adaptor allows fitment of any rod you need quickly and easily & we took this opportunity to put all the parts, for all the current EFR range in one box. All 3 rod options, and every spring you could need are inside the box, ready for you to set up, on your EFR.
Is this a universal product?
  • No, this part number is specifically put together to suit EFR Turbochargers…. However, those handy will quickly realise there is allot in this box that can be customised.You have a few rod options and all the springs. If you have a small bar bender and consider yourself capable, you’d be surprised what you could come up with.
What do I need a sensor cap for?
  • Not everyone will – But for those interested, or pushing the absolute limits… We’ve found havingwastage positions sensor is an important value to data log. We’ve even worked with some engine calibrators on using that sensor for closed loop, highly technical boost control strategies. More data is always better.
What spring options does the Gen-V IWG have?
  • You effectively have 7 options; 5psi, 7 Psi, 12psi, 19psi, 14psi, 21psi & 26 Psi / 1,8 Bar with the use and combination of just 3 springs. And remember, this is just base mechanical spring pressure. Much higher levels of boost can be achieved with some type of boost control or reference manipulation.
What is Twin Port & Why would I need it?
  • Twin Port boost control provides for pressure manipulation on both sides of the diaphragm of the actuator. In the simplest of terms, this means you can have a much broader range of boost control options & often able to fit a much softer spring while still able to run very high levels of boost. This is because you can force pressure into the top cap, keeping the gate shut for longer.
