What is in the box?
You will need everything to get up and going with a Garrett G25 Series Turbocharger. 
 
Is this a universal product?
No, this part number is designed to suit the Garrett G25 series Turbochargers. 
 
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 essential 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 eight options: 3psi, 5psi, 7psi, 12psi, 19psi, 14psi, 21psi, and 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, 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 are 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 longer.
 
Troubleshooting
Wastegate not actuating – Confirm signal hose is plumbed to a pressure only source, confirm preload during installation.
Poor wastegate actuation – Ensure signal hose is not shared and is sourced as close to the compressor as possible, check seal on 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 installation photos.
