Im have searched and read all the relevant stickies. How do you remove all of the AIR stuff - especially the black plastic box and all the hoses on top of the engine. Is there an article that covers complete removal? I want to remove the pump, tubes, everything from my 92 RS TBI. thanks

Pretty straight forward. You'll need to purchase a new belt!

Good luck

 

I need the tube that runs to the cat if you have not trashed it to much. PM me!

 

PM sent...

None of the pics in that thread look like my 305 TBI. Which is which? Belt size? What bolt size do I need to have to plug up the holes left in the exhaust?

 

So you've read all the stickies, and you have seen my posts where I say its totally illegal to do on a street car in the United States, and it will not give you any more horsepower or greater gas mileage, so why do you want to still do it?

A 92 Camaro with only 18,000 miles should be more concerned with keeping it stock looking and preserving it, in my opinion.

 

What is the black plastic box and hoses? The heater hose diverter valve?

Are you obligated by law considering you're a mod to say this everytime someone brings it up? I've made a hobby out of seeing how many A.I.R. delete threads you've hit.... kinda a little game I play at work when I'm bored lol.

 

 

Nice to see that there is always more than one position on every subject. This must be the United States. I respect your opinion. I've been an automotive engineer for over 25 years. The air injection was required to JUST get some cars under the limit to pass the emissions test in place back then. I was planning on removing it because it probably wastes more fuel running it than it saves on emissions. I would leave the fuel injection and cat system intact. I'd still have a VERY clean running car.

The reason I asked is because I have some harware and valving off some other vehicles on which the AIR system is more or less passive. Under certain operating conditions fresh air is drawn into the system to do it's job in the early parts of the exhaust system. You still get most of the benefit of AIR withut the energy loss of running the pump. If you're familiar with early 1990's BMW twin cylinder air cooled bikes you'll be familiar with that system.

Thanks. I'm really enjoying my new to me Camaro and this forum.

 

No, I'm obligated by my love for our vehicles, and my disgust that ignorant politicians are trying to keep us from modifying our vehicles, and even trying to get us into newer vehicles "which pollute less and use less gas." It would be very easy for someone who hates our muscle cars to make a copy of all threads on this website that talk about removing cats, removing EGR, removing AIR, and forward them to a politician who also hates muscle cars. That might cause him/her to write a new bill that would sieze cars that are missing emissions devices and crush them. I dont want that to happen, and I'm sure you dont either. But its possible. In some parts of this country, they already seize and crush your car if you're caught street racing.

 

I heard they only seize and crush your car if you lose.

"The Fast, The Furious, The Crushed".

 

I've got a question regarding emissions equipment. When I bought my 84 Z28, it didn't have any drivetrain at all with the exception of an exploded 10 bolt. There was no emissions equipment on the car at all. When I rebuilt the car I did not install any emissions gear except a new cat and a PCV valve. Did I do anything illegal since I didn't remove any of the components?

BTW, it passes emissions testing without any problems.

 

I think there are still laws forbidding the REMOVAL of emissions equipment. Those laws were really written to keep service people from tampering with emissions parts. You didn't remove anything. The chance that the MAN would ever come after you is zero. Your cat evidently does enough to help your car pass.

 

You sayn the air sistem that was put on these cars dont contribute for lower emissions? and CAT without air = CAT with air?

 

look i took mine out for cleaning up my engine bay i love it now i even bypassed the heater valve and removed all those extra hoses and its great and have had no problems the past few months now you can always put a smop pump delete pulley as well

 

everything contributes - but if he can pass the test without the air pump the rest of the system is taking care of what it needs to. The air injection to the cat helps the cat heat up on cold starts to be effective sooner.

 

I dont belive you can really enjoy a 170hp engine even with a few hoses less. Polluting even more for the same ridicoulous 170hp would make me feel bad.


Looks like you know wery well why its there. If your air sistem doesent work properly and you dont have the budget to fix it, I would understand the removal.

 

Not getting into the pollution bs but that heater hose mess that GM blessed everyone with right on top the engine should be the first to go.....

 

Amen

 

ok - what IS all that crap??

 

I just took off my smog pump and all air emissions 2 days ago. Make sure you plug both exhaust manifolds and the tube coming up from the cat. I also just used the same serpentine belt and just rerouted. Hopefully this helps any more questions on how to do it let me know. Or i can give you pics if u need them on how i rerouted


91' camaro 5 spd rs 305 TBI

 

Send pics to nimrod.sixty9@gmail.com

I also have a 91 L03 5spd... Should be perfect for me

 

How do you get rid of all of it? And does it have any adverse affects if you do?

 

No effects what so ever. So far that is lol. I did notice when in 4th gear i had a little bit more pick up and go at 90mph. I was also going to take out the coolant bypass but i decided to keep it in and just shorten the hoses so that its not sitting over the valve covers but i have not done it yet

 

This pic shows without heater valve and extra hoses. Run the intake to the heater and the heater hose to the radiator. FYI on this intake the hose runs from nest to the TBI unit. It is a Vortec RPM.


HTH

 

would u just cap the hose that comes from the black piece to the center? And what do u do with vacuum line. Here is also pics of what i have and thnx for the assistance

 

Plug the vac and cap the center line on the metal coolant tube on the frame rail below the dipstick.

IIRC DEWEY316 posted some good pics of this several years ago on a related thread.

 

Hey thnx alot for the help

 

 

Doing that today. Those pipes for the cooling annoy the hell out of me.

Dude I have removed EVERYTHING under my hood that doesn't need to be there. No one here and I mean NO ONE in the TBI world can rock my engine bay.

 

so can you remove just the heater hose diverter valve (black box) and plug the hoses sitting on the valve covers? I don't really feel the need to remove everything and reroute my serpentine just yet, i just want to clean up the top of the engine bay/make plug changes etc easier.

 

How come you don't complain about people using your Dad's headers in California? Completely illegal. Even with the AIR tubes, still illegal.

 

PRICELESS!

 

Hey thomas suck in all that air cause im polluting

 

They're SLP 1 3/4" headers, that's why.

And, they dont remove the AIR tubes, nor relocate the cats, therefore they fall until the stock replacement exhaust system provision.
----------
I hope none of your liberal lawmakers in Las Vegas are behind your car, smell your polluting exhaust, and decide to make the smog testing laws tougher in your area.

 

you know what the best thing is i dont have to do a smog test since the car is registered in another state good to be military and if they did wouldnt be hard to find someone to pass it and the best part of all my car as pass californias test tune your car right and your ok
