EGR removal?

[DarkRaptor42]

I was looking at enjuku racings car of the week. They have on there that they removed the EGR, AIV and a charcol canister? Is there any real benefit to removing these things from the engine? What do they do too?

[hopeful]

dunno bout the other things but EGR is recirculation of your exhaust gasses to your engine for th purpose of lowering emissions. Its exhaust air back into the intake manifold.....I didnt kno 240's had em.... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

There may be some benefit, but not much. &nbsp;Most likely you'll get a horse or two. &nbsp;Personally, I'd leave em in. &nbsp;I wouldn't be surprised if removing those items on a stock car would set off the check engine light. &nbsp;Plus, you will have much crappier emissions. &nbsp;Not a problem for you, but if you ever sell it to somebody who has to have it smogged, and you don't re-insert those parts, it'll bite you in the ass hard.

plus its a PIA to get to and remove in &nbsp;our cars. &nbsp;all the way back by the firewall. &nbsp;it's hard enough just to look at it, even harder to get to.

Don't worry about removing that stuff.

[jyt747]

IMO, there's really no point in removing it. Plus the engine light will be on so you won't know if you have a new problem.

[SSJ2Gohan]

Not worth it imo either. &nbsp;As said, its a god damn pain in the neck to get to and remove. &nbsp;not worth the hassle.

If you pulled your engine for some reason, that would be the only time to consider doing it. &nbsp;Otherwise, fogedaboudit.

I really don't know why people are always so eager to remove this stuff... in my opinion, if your car still has a radio or a rear seat, then it is not serious enough to warrant removing emissions equipment.

EGR is inactive at WOT. &nbsp;It makes no difference in power. &nbsp;AIV is only active at idle as far as I know. &nbsp;Again, no difference in power. &nbsp;The charcoal canister is connected to your fuel system; it absorbs fuel vapors from the fuel tank vent gasses. &nbsp;Again, no difference in power. &nbsp;And I bet all three systems combined weigh less than 20 pounds.

[GamblerZ]

It may weight less than 20 pounds, but it sure decreases some of the clutter under the hood. &nbsp;Good for style points. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

I took a trip out of state and somewhere along the way a piece of schmutz got lodged in the seat of my EGR valve wich stuck it open and the fricken thing would barely idle! I didn't want to pay "Joe's Garage" $65/hr. So I limped it back home and took that thing off and threw it as far as I could. And while I was in that mood, I also took off that AIV pump and chucked it too! So there is a good reason for eliminating emission controls.........

i pulled all the emmissians crap out of my FC. it was such a basic set up then. it was intake, maifolds, block, and header. it was great!! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> there was nothing left hardly. there was no AIV, but i did pull it out of the 240. doing so made my car idle normal again. the FC got the EGR removed, it was broken i suspect b/c it made a power difference in a good way. i havent pulled the 240's. the charcoal canister did nothing but bad things when i removed it in the FC. my idle got pretty bad, gas mileage went down the drain for all of like 2 lbs. sucked. id like to move my 240's to the rear passenger side of the engine bay though, but i wont remove it becomes a race car. i just need some hosing now and a little ingenuity.

<edit> &nbsp;by the way, the FC was just a weekend racer. &nbsp;i drove it around occasionally, but an NA rotary with straight pipe from the header back is not exactly a quiet ride! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> the interior was stripped and stereo removed. &nbsp;i had a ported engine, ported intake manifolds, intake, full engine back exaust, roll bars and springs. &nbsp;w00t w00t!! man, it was fun! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

Removing the EGR is a good thing because it keeps your intake side cleaner plus it might reduce the intake temp and if you dont want the MIL to show up there is a way of tricking the ecu with a resistor from radio shack.

If you remove your EGR, you WILL have some idle problems...

shouting out from the Chicago ILL area <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'> I would say that if you do not need to remove this stuff, don't!
On S13's removing the aiv for Turbo's or Sr installs is pretty common because it gets in the way.
FYI, the SR comes with egr in it stock so that should tell you something. I.E. removal of the egr is a waste of time and causes more pollution. It does not effect performance to the point of warranting its removal and the tradeoff of worse emissions is not a good thing. AIV is somewhat useless so removing it is your decision.
S14's do not have it I believe. I was about to say us S13 owners but I just realized. I am a wrecked S13 owner at this particular moment <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>
oh well.

[basemies]

my egr system came disconnected at this black box that is really close to the airbox, and my check engine light came on. &nbsp;i had a lot of idle problems, etc. &nbsp;i slid the piece of hose back into the box and superglued it, and i havent had any problems since. &nbsp;it's not worth removing, really.

[flipboi13]

S14s do come with EGR systems, its pretty small in 240s, but as of now, I'm having electrical problems with my EGR and whenever i turn off the a/c or come down from a high speed, my idle likes to dance between 300-900 RPMs, i swear its trying to match the music i'm playing.....

Aside from some air pollution generated w/o the EGR, the engine was designed to accomodate the EGR system, and you'd have to do some research on the vacuum lines on your car to have it run perfect w/o it. I'm not sure about this, but I heard that people have noticed a difference in mpg w/ and w/o the EGR running.

It may weight less than 20 pounds, but it sure decreases some of the clutter under the hood. Good for style points. <--- LOL!!!!

Removing the EGR is a good thing because it keeps your intake side cleaner plus it might reduce the intake temp and if you dont want the MIL to show up there is a way of tricking the ecu with a resistor from radio shack. &nbsp;<--- why would you want your intake side cleaner?? shows?? &nbsp;And the EGR hardly affects the intake temp that much. &nbsp;For those of you who think things like the EGR are worthless, go to a local community college and take chasis design, every manufacterer has put in an EGR system for a reason.
