i need help running the vacuum lines for an integra with a drag turbo kit. as of right now i tapped into my IM with 1 vacuum going to the bov and 1 going to the wastegate with a manual boost controller. Theres also a fitting on my turbo housing, am i suppose to run the vacuum line from the wastegate to the turbo housing or should i run 1 vacuum line to the IM and 1 to the turbo off the wastegate?

 

You can either run the line from the turbo to the wastegate or from a vac. source to the wastegate.The side port of the wastegate to be exact, leave the top port open.

 

so if im running the vacuum line from the wastegate to the vacuum source. what do i with the fitting from the turbo housing? just leave it open or do i have to close it up with something?

 

you'll need to close it off with something.You can find a little vacuum plug at your local auto parts store that should fit.
