evap canister removal ???

[subinut24]

I just purchased a 96 impreza 2dr coupe 5spd awd for $500. I know, its not a wrx/sti but I'm building it to be a race car. My question's are, how can i remove the evap canister under the rear bumper and still run the car? are there any perks or down falls from this? I don't care about emissions. Mike.

Weight reduction? 3 lbs? (better off switching to light lugs) I can't find a logical reason at all.

You should start a progress thread on your build.

+1 ^ ....Also in 96 ( unless its a 1.8 FWD Cali. spec model) if its a USDM model the canister should be behind the P/S headlight housing next to the ABS/HCU...

seriously, to those of you that have responded, your'e a bunch a f*****g idiots, weight reduction, haha, yeah I'm serious about losing 3lbs. All I asked was if someone could tell me how to remove the canister and still run the car, and I get smart a** remarks, if you dont have helpful input don't say anything. I know enough about subaru's I know that the canister is under the rear bumper on the passenger side, US model, like I have the f*****g money to waste on a '96 cali. version 1.8. in VT. Like I said, if you dont have anything helpful to say, don't say anything!!!

They ARE attempting to help you, they want to know your reasonings behind removing it. It's a standard part on every Subaru and has no bearing on performance, nor does it decrease performance in any way. Why are you so adament, and defenseive, about wanting to remove it? Answer that and maybe someone will give you the answer you want.

Id probably take a deep breath and relax, the person who your screaming at in my best knowledge is a certified subaru technician and knows his stuff. Cali models can be all over doesnt matter if your in VT.

Sounds like a good price. Even if it's not in perfect shape, you should post some pics.

Locate and remove the canister. There is a line feeding from the gas tank that connects in to the canister, do not block off the end of this line. The gas tank requires the ability to take in and expel air though this line.
I'm not sure if this line is hard or soft, but make sure it's attached to something firm and that it's out of direct path of stuff getting in it.

The following PDF specifies it's a Toyota canister spec, but the system is the same on Subaru's.

are there any perks or down falls from this?

Perks

1. Your car will lose 3lbs in an area of the car that could stand to loose some weight. Provided it is located in the engine bay.

Down Falls

1. Check engine light will come on. The ODB-II spec and US Federal Law requires the Evap canister to be installed, and functional on street driven vehicles. Some racing organizations require the EVAP system working (some AutoX classes come to mind).
2. You may be able to have a ECU tuner disable this code, but it's going to cost you a tune. There is not a free/cheap way to tunes your 1996 2.2L NA ECU (that I know of at least)
3. Road debris can enter the tube causing issues.
4. Fuel sitting in the tank can freely evaporate to the atmosphere.
5. Evaporated Gasoline under the sunlight produces photochemical smog.
6. Here's some information about why the Evap system is important.

Gasoline - Wikipedia, the free encyclopedia

Besides lowering the volatility of the fuel, other means of controlling the emission of unburned hydrocarbons, for environmental concerns, exist and are used. All vehicles sold in the United States (since at least the 1980s, probably the 1970s or earlier) are required to have a fuel evaporative control system (called an EVAP system in automotive jargon) which collects expanding fuel vapor from the fuel tank in a charcoal-lined canister while the engine is stopped and then releases the collected vapors (through a "purge valve") into the engine intake for burning when the engine is running (usually only after it has reached normal operating temperature.) The fuel evaporative control system is also required to include a gasketed filling cap which seals the fueling inlet to prevent vapors from escaping directly from the tank through it. Modern vehicles with OBD-II emissions control systems will turn on the MIL (Malfunction Indicator Light, a.k.a. "check engine" light) if it is detected that the gas cap is missing or loose and so not sealing. (The general purpose of this light is to indicate when any of the emissions controls are not working properly.)"]Besides lowering the volatility of the fuel, other means of controlling the emission of unburned hydrocarbons, for environmental concerns, exist and are used.

I don't care about emissions. Mike.

That's fine, there are lots of folks running around in turbo Subaru's without catalytic converters.
However, changing the exhaust is a well thought out, highly regarded modification, with very few drawbacks.

Is 3lbs really worth the hassle that goes with removing this?

If you really want to put your car on a diet look at "AnorexicSTI's" car for inspiration. He's obsessed with making his car as light as possible.
The first page lists every item he's removed from the car. The Evap canister is not on the list.

seriously, to those of you that have responded, your'e a bunch a f*****g idiots,

No one has been rude to you here. Consider this a verbal warning to lighten up; we frown upon both personal attacks and dodging the swear filter to use the f-word in our tech forums.

oh no did I f*****g offend you, deal with it, life isnt a box of chocolates, people are rude everyday, it's what makes us different. You wanna block me from the site, go ahead, I come on here to ask experienced techs/enthusiasts and I get ragged on about my intentions, wrong person to be warning!
