Vacuum line where to connect?

[Esqueda_]

Hello everyone, I've been having constant issues with lack of turbo. My car is running NA aparently...
When I bought it it came with bov so Im removing that butI noticed theres one vacuum line connected to the bov. Where should the line originally connect?

Im planning to have it stock and then find more possible issues.

Right now Ive checked westgate and turbo and they looked ok.

Im replacing turbo solenoid valve today.
Thanks for your help guys

Can you post a better picture? I'm having a hard time distinguishing what is specifically is based on the angle of the picture you took.

On the intake manifold there should only be the hose that goes from the manifold to the PCV. The N80 purge valve will plumb into the intake manifold as well. Most systems that need contant vacum connect to a separate vacuum pump. I can make out some sort of adapter between the intake manifold and pcv hose. this is where a vacuum line going to a BOV would tap into, usually a boost gauge is tapped here as well. If you aren't going to be using those remove the adapter and reconnect the hose directly to the manifold or insert screws into the unused holes to mantain vacuum. If someone did tap into the always in vacuum system you would never have boost as the BOV will stay open indefinitely. The location shown in your photo is at the false port on the intake manifold. It looks like something should be there but the hole is filled in(unless they tapped a port there)

Thank you. Bov was doing its function as I used to have turbo going in and out...
These are some better pictures of the hose from intake to bov(which I have placed a screw in for now)
The only one I installed was the adapter for boost gauge which you can also see there.
So then, this vaccum port connection shouldnt even be there correct?

The last pictures shows the hose going to what I called the false port. Normally that looks like its a fitting but is solid in the middle. I assume it was drilled out to make a vacuum port. Normally nothing goes there.
