hey everyone. i just bought a turbo si and was wondering if i could get some help with some vacuum line issues. i think that's what's causing my car to start and idle low or start and die. i included a couple pictures to show you all what's what. looks kinda goofy. the vacuum line that all of my lines seem to be connected to comes from the back of the edelbrock intake mani. it runs up to a little black cylinder with two bungs. it then runs out and connects to several T fittings. they all run to different things like the fpr, bov, wastegate, boost gauge, and a little black box w/a black wire coming out of it. a lot of people here seem to know what they're talking about. can u all help me out? thanks in advance.

 

Don't those intakes have several vacuum ports under the plenum. I know mine does.

 

yeah, i didn't think of that, but i didn't see any. anyways, is this how the lines are supposed to be routed? it seems that it's all random. isn't it supposed to flow a certain way? i checked my manual, but that told me next to nothing cuz the guy who sold me the car had so much sh*t modified. thanks.

 

You just don't need so many things hooked up to the same source. Especially if you have so many available. I try to have as little "t's" as possible.

 

I have the same thing in my single am turbo hatchback is having alot of vaccum lines for turbo bad? or would it be ok? I know I need a vaccum mantifold because I got vaccum line everywhere.
