    n75 help

    hey guys im having a problem connecting my n75 valve to my holset turbo, i know there are 3 ports to the n75 valve, one goes to the wastegate, one to the turbo inlet, and the third goes to the compressor it self, however my turbo doesnt have a connection for the n75 to connect to the compressor itself, can i tap into the outlet of the turbo to the intercooler instead? or anyone have any suggestions any help would be great or diagrams on this thanks alot

    Yes you will need to be as close to the outlet of the compressor as possible for better boost control or you can tap the outlet of the compressor housing

      yea ive heard from others to tap the compressor housing, i might have to do that, but for now will it due making it as close to the compressor housing as possible, if im not going to tap the compressor housing yet.

        I taped the compressor housing on 3 of my holsets. No problem with that. You can use other outlet also but as jamo said maybe the boost control will be a bit slow.
        Go Holset or Go RS4

          one of my knowledgeable buddies here said to tap into the vacuum lines where the fuel pressure regulater gets vacuum and that will work fine what do you guys think?

            Erm that vacuum line comes from the inlet manifold so no you need a source pre throttlebody!

              Best to insert a tap into the compressor housing.
              Takes all of five minutes at a turbo shop...

              Do not take it post intercooler... always take it from the turbo, the closer to where the air gets compressed the better really.
