jspec intake manifold vaccuum routing HELP ME!
I have all emissions removed. The manual is not helping me because the lines on the manifold are different, infact there are less. on the UIM, I have two facing towards the firewall. The bottom goes to the fpr. The top goes to a nipple on the bottom of the lim. Then there are three that are capped off because the solonoids are gone..they face forward. Then there is one facing the passenger fender. I believe that one goes to the pressure sensor, aftermarket boost gauge, and blowoff. So, I am left with one open nipple on the middle of the LIM, facing inward half way up. Where does it go? Also, where does the nipple on the UIM that is facing up towards that back go. It is bigger, and I don't know what it is for. Also, I heard there is a line running to the brake booster or something...ahk. Stupid j-spec. Any help is appreciated...and the sooner the better, I wanna get my engine running! its been 8 months...

The nipple on the J-spec manifolds aren't different location-wise, there's just less of them. The angled nipple on the inside of the LIM is for the FPR (not any of the ones of the UIM). Only one on the front of the UIM is for the solenoids, the other two are for the purge control valve. The slightly bigger one on the back of the UIM is for the oil nozzle air splitter; the other smaller one is for the primary or secondary (can't remember which) air bleed. The one on the outside of the UIM facing the side of the engine bay is for the BOV, and if you're removed the ACV you can tee the pressure sensor line into this line. The really big one on the back of the LIM (not UIM) is for the brake booster.

Thank you guys. My rebuilt motor is now running. It has been 8 months since it last shot flames. It starts up after being deflooded, but if I dont keep the rev's above 1500 it dies. I have just open downpipe right now, so it sounds like a boat/lawnmower breaking the sound barrier. Anyways...thanks,
Ben
