Vacuum block install

[91Protege]

So i know the best spot to put the feed is in the brake booster line, what lines should I run from it to where?

I ran my bov and wastegate from the block I installed on the BB line. Ran my boost gauge off the stock nipple on the IM.

Thats what I figured. Can I run the boost gauge off it too?

 

[Alejo_NIN]

you cna run anyting off of it but i wouldn't do the Boost Gauge...i like to have the cleanest vaccum/boost read, so i always disconnect something from the middle of the intake manifold and plug my boost gauge there.

Ok I didnt know if it was better or not. Then wouldnt it be better to drill and tap a hole into the intake manifold for the vacuum block?

I just put on a T3/T4 turbo with atmospheric BOV and external wastegate and want to know for sure where the vacuum hose goes on the wastegate-side port or top port?

I plan on getting a central vacuum box/hub to source everything from, but in the mean time I have as follows.

I sourced it from the nipple on the intake manifold with a t one side going to my manual boost controller and from there to the wastegate (side port or top port?) and the other side goes to another t to the boost gauge and to the blowoff valve.

Is this gonna work or what do I need to change?

Thanks

On my vacuum block I have independent lines for the WGA, BOV, and EBC. Then the stock port on the IM for the BPV/WGA is hooked to my relocated FPR sensor and the vac nipple that sensor was hooked to is where the SSAFC vac line runs.

I seee so i think im gonna mess with in the am.

Make sure you cut the brake booster line in the right spot becasue there is a check valve in there. Not sure if you want to put the vaccum block to the left of it or right tho.

 

[hornsfan10609]

You want the vacuum block on the passenger (motor) side of the check valve, the valve is near the booster so if you put it in the middle of the line it will work fine. You can feel the valve in the line if you aren't sure.

Yea I installed the block today, also did some other work while I was at it.

Just wanted to confirm that you caught the note about the check valve in the stock brake booster vaccum line. There should be a "bump" in the vacuum line between the vacuum block and the brake booster (you need to keep the stock vacuum line in that location). The stock brake booster vacuum line has a check valve embedded within it, that prevents the brake booster from seeing boost (pressure). Sorry if you already got that ... Just want to make sure you understand the situation.

It does look like you used new line. You MUST have a check valve for the brake booster! You will notice it as soon as you drive it.

Yea I saw the valve, since a vacuum booster isnt supposed to have boost in it, I just blew through both ends before I cut.
