What is in the box?
You will need everything to get up and go with a Borg Warner EFR Turbocharger. That is, our swivel adaptor allows the fitment of any rod you need quickly and easily & we took this opportunity to put all the parts for 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 that many in this box can be customised. You have a few rod options and all the springs. If you have a minor 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 that having a wastage position sensor is an essential value to the 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 GenV IWG have?
You effectively have eight options; 3psi, 5psi, 7psi, 12psi, 19psi, 14psi, 21psi & 26psi, with the use and combination of just three springs. And remember, this is just base mechanical spring pressure. Much higher levels of boost can be achieved with some boost control or reference manipulation.
What is Twin Port & Why would I need it?
Twin Port boost control allows pressure manipulation on both sides of the actuator’s diaphragm. This is because you can force pressure into the top cap, keeping the gate shut longer. 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.
Wastegate not actuating – Confirm signal hose is plumbed to a pressure-only source; confirm preload during installation.
Poor wastegate actuation – Ensure the signal hose is not shared and is sourced as close to the compressor as possible; check the seal on fittings.
Poor wastegate actuation – Confirm no obstructions in the actuator rod path.
Boost creeping at high rpm – The wastegate flow path is poor, and the wastegate is too small for the application; ensure the balljoint is not seized.
Failing the above, submit a technical request to Turbosmart with information on your engine configuration and installation photos.
