Can a car with a swap pass emissions

[southside]

I have a civic with a obd0 ls swap i tryed to get it to pass emissions but the guy told me the readings for my stock motor .and the motor i have wont match so i couldnt pass emissions. I was wondering has anyone got a swap and passed emissions?If so where did you take it

[EmminoDaGreat]

what year civic.

[southside]

90

[EmminoDaGreat]

you can pass.

[southside]

the guy told me my swap wasnt reading the same specs as the stock motor so it wouldnt work

[EmminoDaGreat]

you can pass..

[southside]

well where and how

[Vteckidd]

put a catalytic convertor on it, make sure your O2 sensors work, turn your timing down.

[RBS]

anywhere that does emissions, make sure everything works good and it doesnt throw a CEL

[joesblk_teg]

well if its obd0 dont they just hook it up to your exhaust?

[JDM onlyy]

you can always do it the illegal way but i don't condone it. Lol

Well I've been back in ATL since March and I've been getting :idb: by the Clean Air Force... I Have a 99' Chassis Which should be OBDII, It's not The Factory computer has since been replaced with a Standalone ECU...

I left some componets of the factory ECU hookedup so the OBDII port is still active...

Does Anyone Know any way I could Pass... ???

You guys help me with this I'll buy the beers

The guy who did it is a dumbass. I would've read what the hood engine size said and kept going. Most of the people who do emissions know nothing of engine swaps, unless you tell them about it. But on the same token, if you make them aware of your engine swap, then they're gonna panic. Overload on their brains. You need keep your mouth shut next time and just go in next and tell them you want emissions, but at another shop. If you feel the need to blabber off, bite your tongue. If the nox is high, retard your timing. If HC's are high and your idle is screwy, change your O2 sensor. If you don't wanna get it done anywhere else, PM me and I'll do the emissions.

Its not tough to do emissions with a swap. Just don't make mention of it as shyne said. If the car is before 96, I wouldn't even worry about a CEL so much. Most emissions regulations go body-like to body like. IE: whatever vehicle you swap the motor into, it must conform to those regulations. Sounds bad, but it is not so bad. Just retard your timing, richen it up a smidge, make sure your cat is unclogged and your EGR works.

And ditto on the emissions. Shyne is a pretty good tech. He'll make sure you pass ok, swap or no.


And no swap here, but I've got my motor modded to the hilt pretty good. Its somewhat easier to pass with standalone fuel/spark management but it takes time.

I've gotten my car to pass every year (3 years now) LEGALLY. When I had the B16 in the CRX I had a stock cat & it'd pass, but then when it didn't I used the "Guaranteed to Pass" & it worked. Then when I got my LS/VTEC (high flow cat) I would only pass 1/3 (or however many tests there are) so I've been turning down the fuel pressure all the way down & it passed 2 times like that now.

so what about if its still obd2? I went the other way 94 ls to obd2 gsr? So do i still get it plugged up or dont say shit and let them keep thinkin its an ls?

[iEvo]

yea it will pass, just make sure all the emisions stuff is working like it should and u should be fine

I had a 95 EJ and swapped in an older model d-series,90-93, and my car passed, barely but it passed. And again never tell the testers what has been done to your car. Shoot I am finishing up a H22 CB7 swap and lucky for me I live in Newton Co., no emissions, but just for the heck of it I want to see if my car passes also. Motor is stock but a JDM H22A. I am making sure all emissions equipment is working and taking my time.
