do a tune-up.

Check the plugs to make sure they're clean, maybe clean out the engine with some sea foam, check for any loose intercooler and turbo connections, make sure there's no exhaust leaks and all that kind of stuff. Also right before you go in to the place to have it smogged, drive the car hard so everything is nice and super hot, it helps the cats work better.

If it really comes down to it, try replacing a catalytic converter, that will probably help as well.

 

Aww crap!

 

I'm going today or tom. and I checked everything that rexbo said. Everything is new. I'll post the out come.

 

I heard that a bunch of rx-7 guys put this additive that makes your car run super clean for the emissions test. Its like a fuel additive that tricks the sensor into thinking it is clean air and it will alow you to pass with like Hybrid car numbers....should check it out. go to www.rx7club.com and search for it

You can get an SR to pass emissions in Illinois? That must be nice, if I fart in the room when my KA is getting smogged I won't pass, effing CA.

thats funny. actually i dont even know if its possible to pass smog in Illinois with SR20. Has anyone in here really passed smog with their SR20? And why is it so hard to pass in CA?? Isnt emission requirements same all around the US besides a few states?

 

CA requires a VISUAL inspection and if you dont have a USDM motor that is either newer or origional, then you cant pass.

 

just lean that bitch out before you go to the shop... sure its not to good on the engine but you'll pass!

 

Well FUCK, I didn't pass either! Here are the results:
Reading:
HC: 19.01
CO: 191.6
Standard:
HC:0.80
CO:15.0
As u can see I failed with flying colors!

 

There has to be a way around this dammit!

 

runnin a little rich there holmes. i would recomend getting a new cat and a wideband and or safc. they will definatley be assets in the long run but those things will definatley get you through this. sorry its a costly answer but thats the only way i can really safely tell you how to lean it out. i mean ou could introduce an unmetered air leak( unmetered air is air theat enters the engine without passig through the mas air flow sensor, hence "unmetered"), but it is unmetered and you will have no way of telling how much you are letting in, so you may run real lean and detonate a bit.
check out this site for any emissions related info, itll help a bunch in understanding how chemicals are measured and how it effects the final outcome, pass or fail. http://www.autoshop101.com/forms/h56.pdf

ps - is your bumper black?

oh yea something just caught my attention. the measurements they took seem to be inacurate. co is measured in a percentage and hydrocarbons are measured in parts per million. so i dont know how they got 191% co and 19.1 ppm of hc. if you only had 19 parts per million of hydrocarbons in the exhaust i dont think the car would even be running. so check the numbers and check their equipment too. if those numbers you gave were criss-crossed, then it would be a valid measurement but yo'd still be running around 12:1 a/f and they dont want to see that type of shit at the emissions station. anyways thats waaay too much gas for cruising at 2500 rpms (around where they test i beleive).

 

Find out what additive they put in their gas that makes your car run alot cleaner. I've heard it works but I can't remember what they put in.

 

ahhh.. Good ole Oklahoma.

I currently have a track pipe on the M3 and knocked out the converter on the 240. Haven't failed a smog test yet. Haven't taken one either. haha. I hope it stays this way for a while.

 

And why is it so hard to pass in CA?? Isnt emission requirements same all around the US besides a few states?

California is the only state in the entire US able to set there own smog laws.....
i have a link to a site explaining the increases in emissions laws and stuff so if your curious ,PM me
yea but it's fun to live here half the time.... but laws are horrible here lol

 

It is possible to pass emission test in IL my brother and I did it. He passed it with completely stock SR including side mount IC, and I had to switch back to stock injectors and lean to hell my SAFC II , run stock boost, and converted my Blitz BOV to recirculation with all this it still was pretty close. In my brothers case I just told him to drive on a highway at high rpms for around 30min and than go to testing station. He went to Palatine station and I went to Lincoln Shire. If I were you I would order new cat and probably get new sparkplugs (basically just do tune-up). I ordered our catalytic converter from summit racing I think it was somewhere around $100.



My test results:

Standard: HC 0.784 CO 9.648 CO2 NA, NOx na
My: HC 0.716 CO 8.460 NA NA

 

God I love living in South Carolina...

 

Bastard:happyfing
salt in an open would lol

 

hm.. i'm obdII what do i do haha i'm fucked 97 240sx with sr swap

 

time to sell your car bud lol your screwed... luckily im in MS and we have no emissions whatsoever... all the cars i've owned have had everything emissions related removed including the cat.:1bowdown your firewall actually starts to look bare after all the sensors arent hooked up

 

Yeah, it cost's an arm and a leg to get your car's registered here in cali when you have a OBDII car.
Ive had my 98 for 5 yrs now with an SR in it and each time smog comes around i bite by teeth.
F***'n sucks!

 

also another tip before you I heard, before you smog your slammed it soo low it can't get on the dyno and they will have to do a smog test threw the throttle only.

 

Hey, I am going to a shop tomroorw to hve my friends turbo gsr passed illegaly because I work at a shop and the owners friend has a shop that is certified in passing people. I can talk to him tomorrow, but know this, its not gonn be free.

 

what do you mean illegally?
your friend is just going to help his eclipse pass with some enviromentally friendlyt help
we don't do anything illegal here:rotflmao

 

ahh i love having a 95... obd1 in NY is eeaasssyyyyy
