Vacuum Lines for turbo?

[Vaddy]

Hey, I am almost finishing up my turbo build for the LFX but I am confused on the vacuum lines. I've heard people hooking them up to the throttle body or brake booster but I have no idea which one to do. Also I heard about the back of the intake manifold near the brake booster? If someone does have a setup, please can you provide pictures I honestly have no idea lol.

It doesn't matter which one, either works. For my boosted build I add 6 port vacuum module to the brake booster (one line goes to my BOV routed along the engine).

Is it relatively easy to do? Is it just cutting a simple line for the brake booster and putting the t fitting?

Also what about the clean side pcv? I don't have any openings on the intake tube, how should I go about this? Would leaving it unconnected have any issues?

When it comes to connecting vacuum lines in a turbo setup, it's crucial to ensure proper functionality and avoid any issues. Here are a few general guidelines:

Brake Booster: Many people tap into the brake booster line for vacuum. It provides a stable source of vacuum, but keep in mind that you'll want a vacuum source that doesn't fluctuate much, as the brake booster requires a consistent vacuum signal.

Throttle Body: Some prefer tapping into the vacuum port on the throttle body. This can work well, but be cautious about potential fluctuations in vacuum pressure during throttle changes.

Intake Manifold: The back of the intake manifold near the brake booster is a common location. Just ensure that the source you choose provides a stable vacuum signal.

Says the honda guy!! Our TB's don't have vacuum ports on them.
