Just keen to know if any of these 3 vacuum lines are really needed for anything, or if I can just block them off?

Also what's the best way to block these plugs off anyway?

1ST PIC: you can either run ur boost gauge there or block it off, there is also one under the intake that u can block off also

2ND PIC: cant see it lol

3RD PIC: if u block it off u will run either no boost or stock boost.. or leave it open and #### ya undies coz then it turns open boost, the thing u wanna do is, see the line commin out the front of the turbo.. plug it into that and u will run stock boost,

if u run a manual boost controller that line goes to one side and the line on the front of the turbo goes to the other side of the controller.

I think the one you mention under the intake is the one in pic 2 (when I first linked it the pic was really small)

The first two pics (ones on intake side) These are required for the charchoal canister setup which is required for unleaded vehicles.

Has a purge line from the fuel tank into the charcoal canister as well as these two lines from the intake plenum. To deal with those nasty fuel vapors.

mildman's has a track car, its not a road car..

also u dnt need the black catch can if its blockd up..

no one runs one,, oh were so rebal LOL

Yep no carbon cannister for me - I found a pic to back that up too.

So what's the best way to block up a vaccy line that will also see boost?

EDIT: Try this link


So referring to this diagram
Pic 1 = 22320P
Pic 2 = 22320J
Pic 3 = 22320H

Looks like 22320H goes to what I assume is the boost solenoid (will do some more reading)

I pushed a big bit of "bluetack on a string" inside the plenum (with throttle body removed). Making sure it caught any aluminium shavings. Then carefully cut off the tube, drilled out what was left and retapped the hole so I could put a grub screw in there to blank it off.

or just get sum silcone line, put a screw one end and push it on, it sucks so it wont fall out but it dnt suck that hard to suck it in

Cool thanks....by the way - does anyone know where these diagrams (like the vacuum line one below) come from?

Is there some Nissan CD or something that is the source?

Is it only something dealers get?

theres sum nissan site, its sumthing like nissnico? or nissannico? i downloaded a whole manual, just google search
