HELP: Vacuum line problems!!!

[nxpoweredsr20]

i have a s14 sr20det and i have searched for the vacuum line diagram but it dosent help me....I removed my canister...I have to hook up a boost gauge, boost controller, bov wastegate, turbo timer,and power fc.....my first question is do i need the wastegate source to be right next to the turbo or is mani. pressure ok? i have the little one comming out of throttle body going to the fpr, the one on the side of the mani to the boost gauge and turbo timer....so i have 2 openings left on the mani, and a small one on the charge pipe.....im so confused....any help is good....thanks alot

if you can, it's best to get vacuum source of the wastegate somewhere on the hot pipe. the bigger one on the throttle body is for the BOV, and the boost gauge tee's off of the fpr line, that's how i've done at least 3 sr swaps without a hitch

ok thanks ...ill try that tom...ill take some pics....there is 2 bigger ones so i was going to run one for the bov and one for the boost controller selenoid...anyone else ?

the boost controller solenoid should go from the nipple on the hotpipe, you should add one if one isn't there, then the other to the wastegate

ya there is one on the hot pipe....that should take care of everything.....thanks alot....which one do you think i should tee off for the power fc ?

the boost control/ wastegate source should be as close to the turbo as possible for best wastegate response.

Any sensors used for boost calculation (boost controller/ fuel management
should recieve manifold pressure. Boost pressure will be higher further down the system do to restriction's (intercooler) causing "pressure drop."

The top left nipple on the TB is the only vacuum source to use. This port only recieves a signal (vacuum/boost) once the throttle is opened past idle. This keeps the recirc valve from staying open at idle/decel.

The fuel pressure regulator and boost gauge can recieve any vacuum source.
Important note: keep vacuum lines as short as possible for best response. If your run out of vacuum sources, consider using a vacuum canister.
