    The N75 is a 3 port boost valve... not sure why you would want to change it for something the same...

I'm new to vag stuff always been jap turbo till I got the Audi.

    N75's are fine... I use one on my car and has 380hp... they wear out as does any other valve but other than that they are fine... N75 issues are usually done to mapping issues...

    standard ones cost the same but with the ones your talking about they will most likely need calibrating? maybe? mapping is not my area so i'm sure Bill or Tuffty will say

    The guy who mapping mine said an uprated 3port would be betterl but it's up to me coz he can set it up either way cheers for your help Andrew. Andy

    Who is mapping it? it won't make any difference to the tune at all...

    Only real differences between 'solenoids' is typically reaction time... you could sometimes get a bigger spike of boost on AGU engine codes using a different N75 valve but on newer ECU's it will go into limp mode...

    N75's rarely go wrong... assuming you have an S3 (from your user name) there is no reason to change the valve unless its proven faulty..
