i am doin a v6 to a v8 swap in my camaro and was wondering if i could get rid of the smog and emmisions items in the engine. If not would the parts from the v6 go into the v8? both are fuel injected.

 

Technically, federal law requires the engine to come from a passenger car of same or later year, with all emissions equipment for that engine installed in the receiving car. V6 equipment, even if it fit (which it won't), doesn't cut it.

Enforcement is another matter.

 

i understand the law requirements. I aint lookin to put this on the road i just want it to run without any problems. The v6 stuff makes sense and thanks for that.

If i am looking to do away with all of the rest is this a possible task even to a degree or will this screw the engine up entirely?

 

Not putting it on the road? What are you going to do with it?

Since you didn't mention your intended use in your original post, we had nothing to go on other than to start with the basics. Driving the car on the road would be the first assumption any reasonable person would make.

 

cant argue with that assumption. my buddy wants to start competing in a local derby race and being a 3rd gen fan i naturally wanted him to run a camaro. We picked one up for a good price but it has a v6. We got a v8 froma buddy but not a complete set up. we are piecing it together but budget is a big stress point. so we are looking to avoid this cost and also remove the clutter from under the hood. so that is why i am wondering how or even if we can remove the emmissions tubing and such from the engine without screwing the car up.

thanks

 

Okay, that helps.

Identify the wires that currently go to the coil (power & tach), oil pressure, water temperature (not the one with the sealed connector), and alternator. You need those. The rest can be taken out.

You'll need the fuel supply line (the 3/8" one), the rest can be capped or taken out if you use a vented gas cap.

If this is a fuel injected car, you'll either need to drop the fuel tank and remove the in-tank electric pump, or wire it up with a return-style regulator (can do this along with a mechanical pump on the engine).

 

that stuff really helps man. What about all of the emmissions lines on the passenger side of the engine.

 

They should come out with the engine and exhaust.

 

will removing the system make the car run bad?

 

You're taking out the V6 and putting in a V8.

You'll be replacing all of the control system (now non-computer carb & distributor) and exhaust (now headers, I presume, and some sort of exhaust if required).

There won't be anything left of the current "emissions system", and none of the stuff you're putting in will be hooked to any kind of emissions system.

I guess I don't understand what you think will be a problem.

 

i am planning on running a tpi setup in the car with the computer and everything, not a carb setup. You hit the nail on the head that i will be running headers but i have a tpi setup. this is why i am curious because we will still have a computer.

 

Well, that's something else you didn't happen to mention.

The TPI needs certain sensors, depending upon which system you get. O2 sensor needs to go in the header collector, you'll need BPS, and MAF or MAP. Plus TPS, coolant temp, knock sensor, etc.. All of those things should come with the TPI, assuming you get a complete system.

You won't need A.I.R. or the charcoal canister, although the canister isn't a bad thing to keep for fuel tank venting. EGR is optional - doesn't hurt anything, but if you eliminate it, you need to tune it out of the PROM.

You can make the system look pretty clean (isn't bad from the factory, IMO). Deleting A.I.R. is the main "clean-up" thing you can do.

 

now we are on the same page. sorry for the confusion, i figured by saying they were both fuel injected in my first post it would have been clear, but it was about as clear as mud. that makes alot of sense.

so as i understand it all of the hoses and stuff on the passengers side is not required to make my car run properly as long as i get the proper prom installed?

where do you recomend getting the prom made?

 

I'll accept some responsibility for reading too fast.

The A.I.R. system only has a minor effect on the PROM tuning, and for an off-road vehicle, probably none at all. The EGR delete is just to keep the SES light off - keeping the EGR intact won't hurt anything.

Learn to do them yourself. You'll have to buy some equipment, but it will only take a few burns to pay for itself.

 

hey thanks man. this info is really pointing me in the right direction. With the chip burning. can you elaborate that. I have never really looked into this or thought this was a do-able project. what exactly does this entail and what do i need to do this.

 

Check out the DIY PROM forum for those details.

 

hey i know you said that the emmisions stuff does not fit a v8 from a v6. do any of the sensors>? they are both maf type engines.

 

I'm not completely familiar with the details of the V6 system, but the barometric pressure sensor is probably the only thing that would be the same.

Getting a full TPI harness & computer, with all sensors, would be the sane way to go. Trying to meld V6 stuff onto a V8 would be an exercise is frustration.

 

makes sense man. I appreciate the guidance bro. im just trying to utilize anything i can off this old system.
