vacuum lines
What/Where did you all tap your vacuum lines for your boost guage and bov? I tapped mine from all the way on the other side of the engine bay.
It reads 20mg of vacuum and +boost just fine. But I want something closer and cleaner, I know the intake manifold has a few of them. I can supply pics if needed.

I tapped mine into the vaccum line from the resonator box on the intake to the manifold. Just t into that line.

There is a line coming off of the #1 intake runner. Tap into that one, and your set. I might have a picture somewhere...

Yeah, all three of these guys are both suggesting a common place to hook the boost gauge up. It sounds like that's what you're using already.
If you have the EJ22T intake manifold, there should be a nice 5.5mm nipple right below the brake booster nipple. This is meant for the blowoff valve. It's a better choice than the other one because it's near the throttle body and is larger.

No, why would you move from the runner, to the BOV feed line?
What is the point?

I am having bov surging problems, and I have adjusted the bov so many times, and still cannot get it right.
I ordered a ej22t intake so I am going to run the greddy type s bov recirc. soon.
But I cant seem to get it right. Is it becuase its made for a WRX (14psi) and I am only pushing 5psi?

right, but it seems when i adjust it it either idles fine, but when i hit any boost it surges.
or when I adjust it again it idles like crap, but blows off fine.
I am hoping the recirc will help.
I heard I can tap a vacuum source for the bottom small nipple on the greddy type s (which is usally left open to suck in air) so to help it get more air faster.

Right, that's what I'm saying -- it simply may not be possible to set your valve to both not leak at idle and fully prevent surge.
I'm sure a recirculating valve will help. You can set it to open at a small enough pressure differential that surge won't happen. It'll open at low loads (like at idle), but that'll be just fine. In fact, it will in theory allow the turbo to spool up slightly faster by equalizing the pressure on both sides of the compressor.

i readjusted my rfl and it works fine now. closed at idle and open under all stiuations that it needs to be.
to answer phil. my engine bay is soo cluttered and moving it is just an attempt to clean things up a little

The valve acts on differential pressure between the inlet and the manifold reference. The differential pressure between the intercooler's end tank and the manifold is very small, even at the flow rates achieved by the WRX's engine.
