Turbo vacuum lines

[ave22]

I recently installed a new turbo. The evo3 I had was shot, so I installed a new Garrett t-28. I noticed that there is a nipple on the compressor outlet elbow, and on the waste gate. (The evo3 didn’t have one there, just on the waste gate.)I was just wondering if I have to T in a line somewhere to connect to that. I do have a MBC.

yes you should, connect the nipple on the turbo for your boost source and connect the wastegate nipple to your mbc with a t fitting running between the turbo and wg to your mbc

if you look at vacuum line diagrams you'll see that they actually have the one on the compresser housing nippled off and just the wastegate is used. i'll try to post it for you.

You need to hook the compressor housing nipple to your boost controller inlet (usually the side opposite of the knob) and then hook the wastegate to the outlet on the boost controller (usually comes out the bottom/side of the boost controller). No need for a tee or anything. Just one hose from the compressor housing to the boost controller and another hose from the boost controller to the wastegate.

do you still have your emissions hooked up? or have you done an egr blockoff?
