Just reciently aquired a 2005.5 A4 2.0T. Intake is off and the turbo was replaced. Basically the intake system was dismantled to upgrade the turbo. There is a TIAL BOV on it and a Garrat Turbo. My question is how can I identify these parts so I can complete this project correctly I was left with. I could not find any kits that matched the parts that are with the car. Also, there is several sets of injectors, none of witch I know what to use for proper fueling. any help would be much appriaciated. Even sources. I have extensive knowledge of Audis and have worked on the for many years, however, I am lost here as I have no expierience with the aftermarke mods but am willing to learn/have to learn to complete this project.
