hey guys, i bought a external wastegate today from this guy. i was just wondering why it has two vacuum ports. one on top and one on the side. why are there two, and how do you hook them up?


thanks for your help.

 

the one on the bottom/side is the one u hook up to your turbo outlet or intake manifold.

the top nipple is for boost controller..

if you dont have a boost controller the spring will open at a set psi..

 

like shorty said. You can leave the top port open if you dont have a boost controller though. Just thought i would add.
