vacuum lines
ok, i've searched everywhere and as far as i understand the left nipple on the TB should go to your FPR,( i have a AVC R boost controller, should my pressure sensor be connected to this??) that line is just plugged, right now there is no FPR connected to that nipple. Next the right nipple should be connected to my SSQ BOV, and the lower one should be capped off. Now my boost controller is giving me weird readings at high boost ill get some reading in (mmhg), when the pressure sensor is connected to the left nipple on the TB, now when i connected to the lower nipple (that should be capped off), it gives me a reading in Kg/cm2, which i think is the same type of measurement unit the boost setting uses, can anybody help me with this??thanks

Re: vacuum lines (luis741953)
well, for the S13 SR
the top two nipples are for FPR and BOV.
bottom one is for evap canister. DO NOT USE THIS FOR ANYTHING BESIDES THAT.
the two on top are different sizes, run the bigger one for you BOV. The smaller one run to your FPR and T into it for your EBC/gauge etc.

Re: vacuum lines (inertiadrft)
this is how i ran mine. and yours should run the same:
Nipple to left of throttle body. Goes to the FPR nothing else! FPR should have it's own Vacuum line
Nipple to the right of the throttle body runs across the engine bay and is T'd off to go to the Wastegate and the bov. The line going to the bov is T'd again so I can run it to my boost gauge.
If you are installing a boost controller. Take the line going to the wastegate and run it to the boost controller. the boost controller should have a line to run from it to the wastegate. The boost controller needs to sit in between the waste gate and the vacuum line running to the TB.
Another option for people running the SMIC and OEM charge pipe. You can run a line from the charge pipe to the wastegate. It sees less vacuum there and if you're pulling too much vaccum for the wastegate this should help keep it from boosting too much.
I'm running smic with upgrade turbo elbow; 3 " dp; no cat and 3" exhaust. My t25 will spool 11psi with these mods. I'm moving my vacuum line to the charge pipe to keep it from boosting so high on smic.
