S14 vacuum sources

[ezza]

Im trying to install my boost guage and greddy E-01

where can i take my vac lines from?

I have searched but cant find anything conclusive, i.e. does it matter if i take a vac from after the TB?

thanks all

The only place that vacuum will exist is after the TB inside the manifold...

I tee'd off the vacuum line that goes to the FPR and use that for my BOV and boost gauge. You could also tee into your brake booster line but I'd recommend keeping that intact.
