vacuum line question

[turboyota]

hello im new to the forum and i have a 90 300zx tt 2+2 (jdm vg30dett swap). but the question i had is the car has custom intercooler piping and the shop that made the intercooler piping had never worked on a 300zx before. I have 2 vacumn lines from each throttle body that arent hooked up. I was guessing that the vacuum lines were attatched to the intake piping. here are some pics thank for the help. ( tried to find similar post could not find one)

So.... Are you asking where the vacuum lines should be hooked up? Or are you asking what they go to?

You are correct, they go to the intake piping. If you need, I could take some pics of where they are supposed to attach.

yeah that would be great . thanks for the help. the car isint runing all that well so i guessed that would bepart of the cause. Do you know what size the vacuum lines are so i can weld the fittings to the intake pipe.

difficult to distinguish by your picture becuase the size of teh piping would tend to show it is the pcv valve that come off the front of the valve cover.. but that flexible rubber hose isnt factor from teh facotr they are slight s bend hoses with a filterscreen inside. they attach to the main plastic intake pipe feedign the turbo

edit : after i read again i realize your werent talking about those.... http://twinturbo.info/ has some good vaccuum diagrams int he delete/ bypass section and im pretty sure you dont even need them..
