Why would you want to remove carbon canister? Its your fuel tank breather...

The carbon canister is filled with active charcoal to absorb evaporative gases produced in the fuel tank. These absorbed gases are then delivered to the intake manifold by manifold vacuum for combustion purposes.

To free up the space for a cold air box.

If removing it is unsafe or cause damage i will not remove it and please advise me if it is.

I thought you were selling your car aaron??lol

[r33madd]

haha can still play with the car and do cost free mods haha

ok i understand that the charcoal cannister aids in emission control. can a tech member shed some more light on this.

When i had my turbo done in my car and new cooler piping and all that crap my workshop removed the carbon canister... i dun know why they did it but they seem to think it doesn't do anything in particular.. it wont hurt leaving it in, they just took that out and put my oil catch tank there... still not sure exactly what its for tho...

[CameronBNR32]

My understanding is that the carbon canistor is your fuel tank breather/removes fumes from the tank when its being filled up or when the fuel is being used (driving). it recirculates into the plenum under vaccum and burns off.

I just pulled the hoses off, removed the canister and blocked the metal lines off with rubber plugs, then fitted a longer piece of hose to the fuel tank breather and ran that to the front of the car.

Runs fine

Don`t get caught without it by police or R.T.A. They would take a dim view of it I`m sure.The fumes from your tank will store in the charcoal powder within the cannister where it will be consumed by the engine under vacume.It has no side effects on the performance of the engine at all unlike hot oil fumes from the valve covers.If you let the fumes run to atmosphere then congratu

lations,your wasting fuel vapours and poisoning us all for no apparent reason.By the way,try taking it off and tap it on the ground a couple of times then give it a shake.If you can hear the granules inside then good,if not then it needs replacing as they are supposed to only last 40,000km.

has anyone got any pics of how they blocked the tubes etc

[BAMR33]

Yeah, where do tubes and stuff go. I'm removing this soon as it will be more effort to keep than remove with the new plenum. Anyone know where that one metal tube goes? as far as I can see it leads down the passanger side rail up and over the motor and then down under the drivers side well.

[markimak]

thats right i remember.. they taught me bout that.. the fuel vapours go through the cannister and any remainding vapours go thru vacum lines to ur plenum...

its not as hard as you must think. you pull the ends off at the canister, shove whatever you like down the vaccum line and put it back on. Be careful as there maybe some residue that comes out of the lines.

why not just Relocate it and stay legal, rather than remove and be epa defectable.

i totally agree...just telling him how to do it if hes so set on blocking it.

thats what i would do.. well actually i belive mine has been relocated to the back of the engine bay cause it looks like someone has crated a bracket for it so they could install a pod filter..

just move it to a better location...

If you let the fumes run to atmosphere then congratulations,your wasting fuel vapours and poisoning us all for no apparent reason.

Actually congratulate Brad @ Chasers for that one cos when i went back to ask for it.... they couldn't find it nemore... took it all of 6hrs to dissapear lol

What benifit to the running of the car will removing a carbon canistor have? i notice in the threat "DIY 13.5 for stockish r33" it also mentions removal of the canister??

[Giveitall]

mine came removed from Japan. i was still wondering how it got complianced. after reading through the threads, i realise i got to have it put back to stay legal.

[Gazee]

But if you want to stay safe with the epa why would anyone own the cars like we do? No one keeps theirs stock and they'll always find something to drill you with... so if your in it to mod you might aswell not do it half heartedly but if it makes no diff in removing it then its no use, might aswell just leave it in.. not that i can talk lol
