When adding a wastegate actuator to any turbo package offered by EQT, it is important to know the orientation of your setup so we can install and calibrate your new wastegate actuator to work with your vehicle. Below is an example to show you which wastegate you have. IS38 orientation has the connector plug towards the turbo outlet (motor side), whereas the IS20 orientation is towards the turbo inlet (firewall). It is important to note that not all IS38 turbos have the same orientation, so it is critical to check your specific setup.
