[PN: TS-0620-4014] Turbosmart Gen-V IWG Borg Warner EFR Twin Port with sensor cap (fits ALL EFR turbochargers) comes with ALL available springs - Black

What is in the box?

You have everything to get up and going with a Borg Warner EFR Turbocharger. Our swivel adaptor allows the fitment of any rod you need quickly and easily, and we took this opportunity to put all the parts for all the current EFR ranges 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 people will quickly realise a lot in this box 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 that having a wastage position sensor is important 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 Gen-V IWG have?

You effectively have 7 options: 5psi, 7psi, 12psi, 19psi, 14psi, 21psi and 26psi with the use and combination of just 3 springs. And remember, this is just base mechanical spring pressure. Higher boost levels can be achieved with some boost control or reference manipulation.

What is Twin Port, and why would I need it?

Twin Port boost control allows pressure manipulation on both sides of the actuator’s diaphragm. In the simplest of terms, this means you can have a much broader range of boost control options and 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.

TROUBLESHOOTING

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 the fittings.

Poor wastegate actuation – Confirm no obstructions in the actuator rod path.

Boost creeping at high rpm – Wastegate flow path is poor, wastegate is too small for the application, ensure balljoint is not seized.

Failing the above, submit a technical request to Turbosmart with information on your engine configuration and photos of the installation.
