some vacuum line ?'s for s14 sr

[quickline23]

hey i just recently picked up this 95 s14 with a s14 sr blacktop in it. now i have a couple ?'s regarding the vacuum lines on it. here is the pic of the ones in ?



i labeled the ones in question excuse the graphics i dont have the steadiest hands lol but here we go

1. has no line or cap on it???

2. u cant really see this one but its next to number one and is capped off

3. go to the stock bypass valve (im guess this will go to the new bov im putting on?

4. just has a hose run and then its capped off?



does anyone know exactly where these wil go or if everything it good i just have to cap of the one that open? any help would be appreciated thanks

i just ran into the garage and looked at my s14sr20,

1&2 are capped off

3&4 controll my Bov and boost/vacuume gauge

run your waste gate/ boost controller solenoid off the nipple on the fmic pipes (the wastegate should not see vacuume, just boost psi)

ok so i just need to cap of 1 2 is already capped off. now 3 runs to my stock bov i will just run this to the new bov. where did 4 run to exactly on urs? mine just has a hose on it and its capped off. can this be used for a boost gauge? or no thanks alot though i appreciate it

does anyone know which vacuum source (1,2,3,or 4) on the s14 SR20 should be used for an electronic boost controller (GReddy PRofec B, spec 2)?

im talking about the line that would go from one of these sources to the main unit inside the car.

Right now I have it as well as the BOV attached in a loop to sources 3 and 4 and im getting boost spike that i cant get rid of Thanks!
