Hey all,

I need to move the charcoal canister in a BNR32. I’m trying to think it over in my head, and i cant imagine it would harm its operation if i dropped it 4" down. Any one? Either it hasn’t come up here, or i cant use search to save myself

Actually, if someone can describe, or picture'ise how the three lines connected to the black cylinder work in purging gas tank vapor into the shared "collector" thing on vacuum, that'd be swell :mellow: I can only guess (1) ones from the tank, (2) another from the valve to the collector, (3) the last maybe triggers the valve to vent the (2) to the engine under vacuum / over run.

Any help would be appreciated!

am also interested in this, as i want to move my canister soon as its the best place for my catch can to go...

where aer you thinking of mounting it, Michael?

Hey Waza,

I’m thinking bout mounting it underneath the corner of the engine bay, to sit in front of the passenger side wheel plastic. Close to the location of the bovs but other side. I figure there’s something glaringly obvious stopping people, as every R32 iv seen either leaves it in the stock location, or ditches it altogether to make room for the PS reservoir re-position.

So far I’m thinking that there’s a in, out and a trigger, and that if its just vapor, then I should be ok.

this also includes a breather from the fuel tank if im not mistaken.

so going lower than the tank will cause a possible siphon effect when the tanks full ?

would only be on an over filled tank i guess sine the breather is mounted to the cap ontop of the tank.

Craved, yah the breather from the tank is the "in" i refer to. What if i run the tubing high first, like up the firewall, thats a fair deal higher then the filler kneck, where i believe the tank breather comes from.

i know the 33's run a metal line, so if you cut it and run a loop you should be fine, however the filler cap breather should only be for when you fill it up, so seals when the cap is back on

Revived for sure!

Level with the strut tower is bout wot?... 2" higher then norm?

Mines been in the lower passenger side brake duct; no worries.

In reality this thread was started by myself with some caution (I have NON now)

The only thing I worried bout was the tank feed. People suggested running a loop (like a toilet drain) but I gave in, and didn't.... all seems well.

Unless your car tips upside down, your ok.. and really.. if that did happen, you aint guna be worrying bout the charcoal cannister.. you'll be checking your dates tits...

... my attempt at humor on a Sat night.. :thumbsup:

Its fumes, not liquid thats the transfer medium.

haha.

all i'm worried about is the fuel vapour.. being near the very hot turbos and dump pipe..

do you think it would cause a safety issue?

edit:

i've looped the fuel line with a T piece and blocked the inlet on the carbon canister, so it should be safer now.

Guys, do you have any photos of the cannister set-up? I've just found out my cannister has been moved before i bought the car, and i'm worried that it's not working properly. The line going under the car (which ends near the cat) has vacuum, and i'm not sure it should?

This thread was started for BNR32's, so i cannot be sure of your setup.

The CC has vapor line from the tank, the purge line and a trigger from the plenum somewhere.

- The f.tank line runs along the fuel lines from the back to front, up over the firewall near the brake lines, past the AC HP lines, and to the thickest lines on the C.cannister.

- The trigger line is the thinest, and on a BNR32 connected the the first (of 6) throttle bodies.

- The purge line hooks up somewhere to the plenum, i forget.

Thread just doesn't die :)

Surely a loop would only add 200mm of hose, and would add, what do the boffins call it? - linear head wall friction something or other? I cant imagine the friction of air and fumes on the inside of a rubber hose would amount to much, def not cause fuel tank combustion / pressurization :)

Regardless, mines been setup as described ok b4 it got taken off the road...

Time well tell, SAU will def know if my car blows up :down:

... dammit, now im stress'in out

    • That's the thing. Especially at idle, changing the cam angle by that much could be spewing more fuel out the exhaust courtesy of everything happening that bit later. More fuel also means more air (if the fuel didn't burn, then neither did the O2) and so the O2 sensors can start to tell interesting but misleading stories. And the specifics of what is happening could easily be affected by everything else you changed as well. And it could be dynamic, where a few revs more or less could somewhat change how the engine is breathing.
    • Good idea on the temp probe. The mv readings of the O2 sensors are very similar to one another, as is the injector pw. I went through logs in the past to see if there was a discrepancy and there is. Because they alternate up and down as narrowbands do.. they do often 'switch' as to which one is more. They were never 20%+ (more like 1-2%) so it's possible the difference between 20 and 15-17% is a similar discrepancy to 2.0% and 1.7% which I wouldn't have really noticed in the past. We did think about spacing the strut brace. Unfortunately the ~20mm that the GTR brace is lower than the GTT brace is effectively what you need to clear the vents. Moving it up would make it very uncomfortable, but it's plausible that 10mm is a unhappy medium between both hard places... The good news is.. using MR HAMMER it was actually pretty easy to bend back the bent bits to make sure the guard and headlight/new headlight tabs line up right. Yes, we used a R34 GTR guard to make sure the bolt holes all lined up with a known straight guard. As above, you can see the side skirt and the GTR guard are not meant to play together, but everyone seems to think this is a simple fix to the point where nobody who has had these talk to one another mentions how... ...so I'll just assume they know how to fix it when it comes to paint jail time again. Whoever they are. Nobody returns my calls. There's so much changed with regard to the ECU and the car.. that the next step really is to connect the scanner and attempt to drive the thing. It'll be pretty clear pretty fast how in or out everything actually is...
    • That's nasty! I think there is perhaps an inherent problem is using elastomers in such environments. The whole thing can and will get quite hot, and elastomers are not famous for their temperature resistance. On top of that, if the components are cast rubber or urethane and so on, there might be QA/QC problems with bubbles or voids in the material that could critically change their performance. They might just tear apart after being squished (presuming that any elastomers are used in compression rather than tension, I'm thinking that you squeeze one with a void in it and it tears the wall of the void to the outer edge of block, then the next time it extends or otherwise twists, it just gives up). This is all purely hypothetical, but it makes me wonder if the things that they have put into it to make it nice to use/live with are perhaps going to cause occasional failures like this. I wouldn't be getting up in arms over it, unless there are many repeats. I have personally ruined an Xtreme clutch - just an HD thing. I can't remember if it was still behind the 20 or was after the 25 went in. But it inverted some of the retaining spring/clip things around the outside. No-one could explain it. It wasn't thrashed, there wasn't heaps of torque being put through it, and there were no obvious problems other than the above. They were quite concerned by the event so they replaced it even though it was a few years old, which was very nice of them. As far as I am concerned, these things happen with clutches.
    • Any damage to the box/input shaft?
    • Hey there Mate , I just got my local guy to install it Waterhouse Performance, Penrith (specialise Nissan/Datsun and other performance cars) , you can do it yourself if you like , AMS has instructions on their website.  Cheers Pac
