it goes to the pipe on the left of the plenum, the other end goes to the wastegate or boost solenoid if still in place

I already have one pipe going from the left of the plenum (as you look from the rear of engine bay) to the actuator via a bleed valve. My solanoid has been bypased completly. I just have a etal pipe poking out the top of the intercooler now thats not even blocked off?? how strange lol

the metal pipe was originally used to route the plenum pipe, obviously it has been routed around the intercooler now. (the metal pipe exits below the intercooler, nissan must of thought it necessary to put this pointless bit of metal pipe in)

both ends are probably connected to nothing, take the intercooler off and youll see its just a small bit of metal pipe to help with routing

Cheers for the info on the TMIC pipe tho steve 8)

B1A3d,

your vac at idle is to high, mine is about -40/-50 Hmmg?? or someting like that (mm of mercury) so it does look like you have a leak somewhere

not sure, some conversion website says that is -67 on my gauge, so that seems good (if I read the website correct)

oh actually i just read my guage a bit better and it seems possitive pressure is read in PSI and vac pressure is read in HG. so thats means i have around 13 hg at idle.

well we seem to have 600 views and 30 odd posts for a bit of plumbing.

Im just gonna start ripping shit apart and going from there because it seems we have the people that like to read but not help.
