Ok, so I've got the engine I'm building all most put together now. I'm at the point of putting my CA20E mani on it and then running the vaccum lines. I have to pass an emmissions testing program (Aircare) to get insurance for the car. My question is what emmissions devices can I "delete" from the car without harming my chances of passing? I know that the EGR is pretty much off limits but what about the carbon canister? It's pretty useless anyways right?
why would you want to get rid of the carbon canister? that dosen't give you any hp gains that I have ever heard of...
And why not just leave it all on till you get it checked then take stuff off?! :wink:
I agree. How would you know exactly what the problem was emissions wise if you change too many things. Wait until you get inspected and then start taking things off.
As far as the carbon canister goes. I have no idea what impact that stupid thing will have on emissions but I think it will be negligible.
actually!!
removing the EVAP(carbon canister) will give you BETTER emissions...
the carbon canister will raise your co2 levels a bit because it holds unused fuel in there and then sends it out the exhaust or somthing along those lines...
so when you go to aircare with it off, your co2 levels will be down a bit...
but then again you'll be dumping that stuff directly into the atmosphere...so...it's a toss up...lil higher co2 and have "worse" emissions...or add to the polution and have "better' emissions
*flexes biceps*...see..I'm the king of the ca18et too ;) bahahha
The evap system recycles the vapors from the fuel tank and puts them into the regular induction system (i.e. intake). If it did dump it into the exhaust HC would be high becuase it would basically be fuel. The carbon canister's sole job is to ensure that only vapor enters the intake tract
Like I said I don't know how it affects engine emissions if at all but evaporative emissions would go up... like anybody gives a ****... a gas can emits 1 million times the evap emissions of a car and the enviro-mentals don't cream their pants about that.
:p

teehee j/k what's up with westside's threads ending like this anyways?
I leave you guys for like 6 hours and this is what you come up with.... :gay:
J/K
Yes I have though about just putting it all back in and then taking it out after, but becuase I'm using the CA20E mani I have to reconfigure all of the vacum lines so that everything works the same as it did before on the CA18ET mani. So if I get rid of unnessary stuff that means I have less stuff to figure out.
Well there is one very important line to keep. This is the one that is about 1/2 inches in diameter which attaches from the intake manifold, and goes to the intake pipe. if you look at the intake manifold from the fron of the car, it will be to the left of the TB, a couple inches back, and a couple inches down. It is a metal pipe that goes to the back of the ntake manifold...somewhere...in any case this one controls the idle when cold, and to a certain degree when the engine is warm...if you do not connect this line the car WILL NOT IDLE!!!. The cars like it better when att the lines are connected, so I wouldn't be disconnecting anything until you have it emissioned...8)
Better to leave it all alone.
And as for this whole king of this that and the other ...
I have 4 vacuum lines left :finger:
My car also blew up, but that's besides the point.
Odds are most of your emissions devices are no longer functioning as it is, but if you disable it and then fail the test, you have the headache of trying to put it all back together. I nuked all of mine because a) the car was running like crap for no reason, and b) it will never be etested.
The car ran a million times better, but still.
The EGR can be disabled very easily by just disconnecting the solenoid.

what does that look like, where can i find it?
On the american CA20's it is on the drivers side in front of the shock tower. there is a grey connector, and you just unplug it. when I un plugged mine the car became more sluggish, so I actually reconnected it...8)
Same location on the turbo car

Not necessarily a power mod, but if your EGR is faulty, you might be surprised.
There's other stuff missing in the pic, but that electrical connector just hanging out there ... that's the one.
