    Hi all,

    I need some advice please!!!

    I have a project car Golf mk3 2.0ltr ABF 16v Turbo. Running DTA S40 PRO managment

    What i would like to know is what goes where...

    Do i need a N75 valve?????
    N75 - F version.
    T piece connection
    Long horizontal connection
    Short horizontal connection
    and connection point down.

    Audi S2 Turbo
    Where does the connection on the compressor housing go to? (this is the tiny pipe that stick out to where the air filter connects)

    Audi S2 Wastegate (With adjustable hex nut on top, also the is vented to atmosphere)

    Sorry. It is difficult to understand what you know and don't know about the basic Audi 20V turbo system from your questions. Here are some links and diagrams that might (or might not) help you:
