Ok, Ive been searching thru the engine bay clean up threads and the TPI threads, but with the kids buggin me, I dont have time to find what I need.

Here goes: Can I still drive my TPI Camaro minus the smog equip and possibly the cat conv? I dont have to worry about emissions testing. I want my engine bay to look cleaner. The cat question comes from my TB car not having exhaust past the manifolds and I want to put my TPI on that car after I install the new heads and stealth ram on my B4C. I would like to run headers and the "off road" y pipe. What kind of issues am I going to run into?
Sorry if this thread is a rehash and therefore redundant, but I would love a straight answer. If you have any questions for me that would help you answer me, then shoot...I check this site every few hours...thanks guys!

 

yes you can drive it with no prob just get your smog pulley delete, now since you are deleting the smog you gotta replace the cats (if u wanna use any) because the stock ones have a breather tube that get the air from the smog pump. try to keep the o2 sensor tho because if you don't you will be getting a code and the ecm will not behave as it should

 

IMO, you will require some sensors that are considered emissions equipment... your TPI injects juice through various calibrations that your ECM calculates.... you can delete your CAT if you don't have an O2 sensor after it...

 

its a 91 the only o2 its on the exhaust manifold so he should be able to delete the cat with no prob theres really not much else that goes to the ecm i just replaced the wiring on my can and for the emissions there were only like 5 wires going to ecm and most of them were power for the A.I.R.divert valve...

i have the diagrams and pinouts if you need them so u dont have to go through tons of info to get them

 

only thing will have to keep is the EGR valve, EGR Solenoid and vacuums. the ecm needs this or will run in open loop

 

@juanillox8- YES that would be awesome...I so appreciate it. So if I want to run headers, then I have to get the ones that are listed "with emissions"? or can I get the non emissions headers (Cheaper) and just get an O2 bung welded in place?

 

do your manifolds currently have tubes coming out the top? if they do then you have A.I.R. which is part of emissions... you will have to get a set of headers with those tubes...

 

If you mean those tubes that are making it a huge pain to change the plugs...yes. Is there anyway to bypass that system?

if youre familiar with this thread, then is there anything else you would add to it?

 

removing your cat is a federal offense...doesn't matter what state you're in.

removing your o2 sensors would be the dumbest thing you could do to your car. it will completely throw off your ecm.

 

&

Regardless of emission in any State.....It is a FEDERAL offense to remove any smog stuff.

So even if your state doesn't require testing, a car without the smog stuff (pump, A.I.R. tubes, catalytic converter, etc.) SHOULD still fail visually.

Yes, many states that does not require testing have inspectors that think since there is no testing, it doesn't have to be there. Well.....Their wrong. FEDERALLY wrong.

 

@aks- As I stated when I started this thread, Most of these questions are regarding moving my TPI to my other car, which has no exhaust past the manifolds and no emissions equipment on it whatsoever. I wanted to know if I put my TPI on this car, without all the smog stuff (ie, its already gone, I never had it since Ive owned it)would it still operate properly, if not what I would have to find from salvage yard or whatever. I am well aware that removing the Cat is illegal. But I really do not want to spend a lot of money on things I "dont need" for the car to run well enough to have fun on weekends and go to shows. If I have to go yard out a bunch of smog crap, then I'll just go with an old school carbureted engine.
As far as removing my o2 sensors, I said nothing of removing them, I just asked if I needed the headers with or without emissions. Believe I even mentioned welding in the o2 sensor bung.

I appreciate people making sure that others are aware of the laws regarding cats and what not, but please...leave the lectures for my professors!

yes the easiest is to get the off road headers and weld the o2 sensor fitting now once you put the headers on u will be removing the tubes that are on the way for the plugs, those tubes run from the AIR pump to the intake manifolds to the cats thats all ur emissions

 

Federal... LOL!!!

 

Hey I'm just letting you know. do what ever you want i could really care less

I know two different people paying $20,000 fines for punching their cats. Also a whole dealership near me was shut down for removing 3 people cats, just shut it down no questions asked. they had the proof. and my state isn't even strict at all on emissions.

 

@aks- c'mon man...Im not lookin for an argument...I appreciate the info, I really do. I live in eastern Washington, farm country. I didnt even need to get my car inspected at all. My red RS has no smog already...one of the prior owners yarded that **** out a long time ago...I want to put a TPI motor in it...so I am not removing anything as far as smog equipment. ok? Back to topic
I got under my B4C, and there is no cat there either...the tube is cut and crimped. So all the AIR crap under the hood is just for show at this point, would this account for my car running poorly? after the car is warmed up, it acts like the timing is off a little, and the RPMs at idle fluctuate between 700-1200. WTF???

 

checked vacuum lines? checked timing? plug wires? plug gaps?

 

New plugs n wires (problem started before this), cap n rotor, timing within 1/2 degree. All vacuum lines seem to be in place, and in good condition. I saw in other threads that the injectors may be out of spec, but haven't been able to check with multimeter yet...dont have one.

 

Just checkin to see if my new signature pic will show up

That link shows how to delete the AIR pump and not need a delete pulley. I am running it that way and have no problems with it. Yes you can remove the AIR equipment and have no ill effects. You might want to consider putting in a hi flow cat as they are cheap at $65 and will eliminate alot of hassles. If you use headers get ones without AIR pipes and get a O2 bung welded in then consider getting a heated O2 sensor and harness for such as it will be more accurate.

 

@bonesbrakr---THANK YOU SO MUCH...Im sure I would have found that article the day AFTER I install a delete pulley! Dont suppose y'all know about deleting bothe the smog and ac? Would I have to run regular pulleys and standard rotation water pump? It would probably be easier to just install the AC delete pulley and go that route. Thanks, you helped me answer my own question.

 

So did you end up removing the emissions, because I'm also from Eastern WA and am looking to get rid of all this stuff(I already got rid of my cat) is there any vacuum lines that need to be plugged in order for my motor to run as usual?

 

Haven't gone after it yet. As far as vacuum lines, I dont know. I bought a haynes manual off ebay so I can look at the vacuum schematic and make sure everything is in the right spot now, and I will go from there. You ever come around Colton let me know. Love to check out your ride and maybe we can bounce ideas off eachother.

 

You are aware the more you modify your B4C car the Les its worth.

 

I dont know why hacking the car apart is such a popular idea. There are not many decent 80s camaros out there anymore and it seems like everyone wants to ruin the ones that are left.

 

Just to let you guys know, my B4C has been hacked on by previous owners, been in a wreck, and I really have no illusions that its going to be worth a lot because of that. Im just trying to enjoy mine, and if I wanted to make it all original, I would have just as hard a time now as I will after I remove some of the smog stuff and what not. I am keeping all the things that I do take off the car, along with pictures to document everything I do. I dont think that Im going to ruin my car by personalizing it to my tastes. The AIR tubes are just for show at this point, and theyre in my way, not to mention ugly as hell. So, thanks for the concern, I understand.

 

yes, well you really don't see a difference unless perhaps you are doing quarter miles or something...I've ran my car with my CAT gutted and saw not one difference... ..

 

Today i put 2 new cats on my B4C to pass smog that wasn't cheap but i have to say the exhaust sounds so much better then it did with 2 cats that had nothing in them.
I was going to replace the magnaflow muffler because it sounded so pathetic now i might get another year out of that old magnaflow.
Oh yea it runs and idles better amazing.

 

hey if you do take the stuff off your B4C send it my way. I'll even pay shipping or haggle a price if you want. my b4c has no sign of emissions stuff or a smog pump delete pulley. so i don't even know what size belt to get for it. Trying to restify mine and would love to have the original smog stuff.

i know but I want it to look stock or damn close

 

Hello
Just found this thread. Thought I'd post my thoughts as I am doing the same thing.
As far as the emmisions, just make sure you pull all the tubes and replace the cat. this is what i did if your interested. Sounds really nice.

Here is a video of what it sounds like.

Here are pics of the exhaust.

I did not use a smog delete. Route the belt as you saw in the article but I used the 960K6 sized belt. Works great.

As far as the o2 sensor, use a three wire heated sensor because the stock sensor won't get hot enough to close the loop and your car will run like crap.
This is the one I am getting. It's already wired and adapted for a single wire thirdgen. Some headers like mine come with a bung already on the collector, you just have to drill the whole before installing them.

Hope this helps you. If not ask me again as I was trying to follow the reply but I started getting lost in the off topic responses.

 

PM me. I have 2 91's and both have all the smog tubes and what not. Im gonna save the smog stuff for the B4C, but my 305 tb RS has the same stuff, and Im going to throw an old school motor in that. It doesnt have the cat anymore, but the smog pump, AIR tubes and all that are there. If you would like them, then we can work something out.

 

Thanks for the info man, btw your car looks great!!!
