S13 SR20det Vacuum line setup

[cotbu]

I'm going to say this. Have you ever seen the stock vacuum line routing?
Okay I have the vacuum T'd from the Fpr to a vacuum/boost gauge and i can see if it ever looses vacuum or whatever!

There is no right way to run these lines, but your current routing of no fpr vacuum is wrong!

I wouldnt...NEVER EVER T-off shit off the FPR line. The FPR should always have one line dedicated to it. More shit you T-off on it, the more chance of you getting a leak causing the FPR to not work properly. FPR dropping your fuel pressure at WOT...one of the best way to lean out the engine and blow it up

this old school super street type shit. we monitor everything now! if you don't have the gauges to monitor your setup what does it even matter. He didn't even have the fpr vacuum connected.

Again I monitor my boost, as you should if you see the boost is not correct or even if you vacuum is not correct get out and check something, but if you have noway of monitoring any changes how will you know.

Ultimately you need to decide for yourself. My routing works for me and has for quite awhile. I have never rebuilt this engine, but if it blows right now, I would have gotten every penny i put into it out of it. My SR is probably older then your license!
