i already made an adapter for the turbo intake side but it wont hold any boost:1zhelp::aigo: do i have to plug off any of the vacuum lines or any hoses?? thanks.

Find where it is leaking from. It should be a sealed system. So if it isnt holding the pressure then it is getting out somewhere. Shouldnt have to cap anything.

Can you post pics of your adapter? I am trying to find a way to do the sam to mine. did you find where you leak was?

Go to a hardware store and look for a big rubber cap, same inner diameter as the outer diameter of the intake pipe. Then use a valve stem for tires mounted in the center of it. Apply air like you are filling a tire.

Thats what I did on my TT3000gt. I lost it so I cant show a pic of it.
