I personally like using a vacuum block to simplify house routing, like this one.

First, cap off that nipple on the turbo. Use your intake manifold for a better boost/vac signal.

Manifold -> vac block
vac block -> boost gauge
vac block -> boost controller -> wastegate
vac block -> BOV

Each arrow is a hose.

Here is my vac block with outlets to boost gauge, meth injection controller, BOV, and wastegate.

Or have an intake manifold with the ports welded in ;)

Interesting. The instructions that came with the eBoost2 specifically say to route off between the turbo and the intercooler, preferably right off of the turbo housing. I had a port for it on my intake, and capped it because of what the directions said.

I can't use that manifold. Idk how to set up the iacv on that and different pipe. Be nice if I didn't need diff pipe for that manifold.

As for the boost controller routing, you would want the boost controller between the boost source (turbo housing or IM) and the wastegate. I would tee the boost gauge to show what you are seeing as the selected boost level, so it too would go after the boost controller, or on its own source at the IM.

I'm going to thread-jack a little bit, anyone know if you need to put in one-way valves in the vacuum lines that go to the intake manifold when you go turbo, like the vapor recovery system, or any of the other lines that come off the intake? Only the brake booster comes with one in it. I'm not sure what will happen if you expose the vapor recovery system to boost.

Because you brought it up, here's how I'm getting around the IAC and the vacuum port sources with an aftermarket intake. Keep in mind that it has not run yet, so my remote IAC is as of now untested.



I'm using -10 AN fittings, the top one is welded to my intake piping from the intercooler, just before the throttle body. The bottom one is welded on the intake just after the throttle body. My hope is by keeping these lines very short, I will minimize idle speed hunting.



Here is the remote IAC mounting plate, resting on the intake runners for the pic. I had aluminum -10 socketless hose barbs welded to it, the stock IAC screws on the opposite side. I'm going to run just enough hose to bridge between the two fittings shown earlier.



Here are the vacuum ports I had welded into my Jay Racing IM, in lieu of running a vacuum manifold. I can't say that a vacuum manifold won't work, or that you'd definately see a difference doing it this way, but I can't see where each thing needing a vacuum source would be hurt by having it's own port. Certain things, like the BOV, specifically say not to share with another item on a tee.

What about the sensor for it thou? Doesn't that throw a CEL. Or brake booster. How's that set up?

You dont need the BAP switch , use the manifold for the boost ref to the WG and to the BC and keep them short
