hey people, i'm about to get rid of all that emissions junk so i can free up my engine bay and get back those few lost hp's is there any website or tech article to do this? who has had experience with this kind of thing? will it mess up the computer at all? ALSO- i want to take my a/c out since I dont ever use it- what all do i need to complete the project. I know i need the a/c delete box but i'm not exactly sure how that works- can you experts help a brother out?? :hail:

 

Do what you want with removing emissions equipment, but I'd recommend reading this thread first. As for messing up the computer by removing emissions equipment, the main thing that comes to mind is the EGR valve. Removing it requires disabling it in the PROM.

I removed the A/C on my Camaro and it wasn't a big deal. Just go in there and see where the lines run and remove them. I'd suggest getting the drier (the metal canister) drained before you do anything -- I knew that mine wasn't drained when I took it off. Be prepared for the R-12 or R-134a (depending if you've converted) to shoot out... you might want to cover the front end of your car down if you don't get it drained at a shop. Other than that, it's basically straightforward. After you have the lines removed, unbolt the drier, the compressor, the consdenser (in front of the radiator), and the evaporator (located in the heater box). An A/C-delete heater box is the way to go, though I've seen them go as high as $80 on eBay. It wouldn't hurt to try a junkyard... apparently, some older GM trucks have the same design heater box. Lastly, if you don't want part of the compressor bracket sticking up, you'll need a power steering pump bracket from a non-A/C engine. That's purely cosmetic, though.

 

blue86iroc- thanks for the input- is there any websites that maybe have some pictures of the removing process? thats the best way i learn- or i can always read something about it, thanks bro

 

Not that I really know of. If you have a GM service manual for your car, that should have pictures and detailed instructions on removing practically ANYTHING. If not, a Haynes or Chilton's manual will have some information and pictures. For $14.99, it couldn't hurt. The GM manual is far more, usually around $100 or so.

 

i've got the chiltons manual but it doesnt help all that much- couple questions--

1. what does egr stand for-i keep hearing it but i dont know what it is.

2. can you give me a brief description of what each piece is and does?

 

1. EGR stands for exhaust gas recirculation. During normal driving, the EGR pumps exhaust gas into your intake manifold to improve emissions. Whenever you push the gas pedal to the floor, EGR is automatically disabled to produce the most power (exhaust fumes mixed with fresh air isn't ideal for performance).

2. Did you see Grumpy's article? He pretty much explains operation of everything. Stuff he didn't mention: the PCV valve ventilates the crankcase; the charcoal canister retains gas fumes and prevents them from leaking into the atmosphere; and the O2 sensor monitors the air/fuel ratio -- it's used by the car's computer to regulate the amount of fuel it injects to compensate for the air it takes in.

 

where does the chacoal cannister sit?
are most of the misc small hoses and stuff all the emissions junk?
do you think i'll pass emissions by taking all that stuff out? i had a really really low emissions when i got the car- you couldnt even see the reading on the chart it was so low- will the emissions stuff being gone cause that much polution?

 

The charcoal canister is the round cylinder on the driver's side engine compartment, right behind the headlights. You'll see a bunch of hoses and vacuum lines running to it. Some of the miscellaneous hoses are emissions equipment, but some are also vacuum lines that operate your power brakes and your fuel pressure regulator, just to name a few. If you look on the underside of your hood, there should be a label near the latch that explains emissions hose routing.

I highly doubt that you'd pass an emissions test with all of the equipment removed. After all, that's why it's there . Also, what you determine to cause "not that much pollution" may be considered terrible by the EPA -- they're some tough folks. I would suggest talking to an inspection shop and seeing what they look for. Here in PA, my car can become emissions-exempt if I put less than 5000 miles on it per year. Rather than limit my driving style, it's easier for me to deal with the emissions components and maintain legality... there's really not that much extra horsepower to be had, although it does clean up the engine bay nicely. Also, they check to see if the car still has its smog components. Meaning, you could pull everything off and pass the sniffer test with flying colors, but if you don't have a catalytic converter, AIR pump, etc. (the stuff the car came with), you won't be able to get a sticker. But that's here in Pennsylvania.

Try doing a search on removing emissions equipment; I've seen threads about it in the past.

 

With all your questions about the Emmission Conrtrol Equipment,
I think the best advice would be to leave it alone before you screw up BIG TIME...

 

no no, see thats WHY i'm asking all the questions so I DONT screw up big time- how else is one going to learn?

 

Thats Not the way to learn about your car by pulling All the Emmission Controls Start by doing the little things change the spark plugs for example amd read up on the workings of your car. Not by pulling something you call JUNK.

 

generally speaking- anything that doesnt add power and make the car handle better is pretty much junk. Dont worry about me messing my car up- i've done much more difficult things on my 91 than removing a couple lines and misc. parts. This thread was posted for positive input on how to remove the pieces, not insults. So i'd appreciate that it stay that way. Thanks

 

Go to it fellow.....:lala: :lala:

 

91, DJP87Z28 does have a point. I've just been answering your questions, but you should really do some more basic things before tackling a project like you're talking about. Removing any and all emissions parts can be a long an involved process. Just referring to the charcoal canister, if you don't connect those hoses properly you could release fuel vapor (or worse, liquid gasoline) into your engine compartment and possibly start a fire. Don't forget what I mentioned about changing things in the car's computer chip, the PROM. It's designed to run with emissions equipment, and if you pull it off it may run worse. Unless you REALLY feel comfortable (and I mean not a doubt in your mind) about yanking all the smog equipment, don't do it. I don't want to sound harsh, but I don't want you to turn your Camaro into a paperweight.

 

definitely understandable 86iroc- and i definitely appreciate your input

DJP- no offense taken to your comments- maybe it is a little steep of a project without more research.

mainly, i was planning on removing the a/c since i never use it, and i thought it'd be a good idea to go ahead and remove everythng along with it.

any ideas about takin the a/c out?

 

With the A/C removal, just look at what I wrote a few posts up -- that pretty much describes everything. There's probably a few things that I missed, but it's really just common sense... see where the bolts are and take them out. I had a little trouble finding some of the bolts that held the compressor on, but that was on a V-belt engine. Since you have a single serpentine belt, it might be easier.
