So everyone in California can have an SR20 now?

No, they closed the BAR referee stations for a short time this summer (5 weeks I think, I'd have to look it up), but reopened them. If you had a ref ticket go to court at that time, you could say that you called but they couldn't get you inspected, and I heard most people ended up having to pay the fine anyway.

Regardless, Ref stations are back in action now, and cops are certainly still writing the tickets.

Most likely, if everything else is completely legit. Problem is, most of the cats from ~15yr old cars are 15 yrs old, and have seen more than their recommended 80,000 mi, so any increase in NOx and HC from the cam overlap will definitely show up. Maybe someone who's tried to pass with 248/248's can comment.

Okay, I got one. I've been trying to pass the state ref in my sohc for about 2 months now. Here's the breakdown. No check engine lights and I've passed everything really clean except for NOx. It's starting to get on my nerves. Here is the #'s I'm getting.

HC CO NOx
max ave meas
15mph 118 31 26 0.75 0.100.01 799 2371666
25mph 93 20 24 0.63 0.09 0.04 738 199 321

Here is the list of parts I've replaced. Most were just maintenance but they also help.
-plugs
-plug wires
-thermostat
-cts
-fuel filter
-all vacuum lines
-I've also seafoamed the engine(before swapping plugs) and removed the egr valve and cleaned it along with the bypass pipe, and transducer.

So here is the issue. My car isn't getting hot enough. After driving to the ref they check it with the laser thermometer and it only reads between 110 and 130. The thermostat opens and the hoses pressurize, but I just don't get why it fails only at 15mph. I thought it was my fan clutch but after checking 2 other stock sohc's they have the same resistance when trying to spin em. I think I pass at 25 since the rpm's are higher in 2nd gear so the motor heats up more. I think that at 15mph the rpms are too low to heat the motor up enough. The ref even runs the car on the dyno for a minute to warm it too 150 but it still fails. I'm stuck and any help would be appreciated. Sorry for the looooooong post.

Maybe get a hotter thermostat, turn off the fans, drive through Van Nuys in August.....it will get hot.

Stock fan clutch, no e-fans. Not interested in hotter thermostat. Not trying to drive all the way to Van Nuys. Anyone else got any ideas? Got another ref appointment on monday, and I want this done and over with.

How about a new thermostat? Thermostats are designed to fail in the fully open position. That could be the reason why it's not hot enough.

test only shops are more inclined to test the car as is. we want you to pass, free retests cost us money. however, we are so closely watched, that if your shit fails (for one reason or another), we usually don't cut you any slack. get out of here, get that shit fixed somewhere else, come back for your retest, gtfo. test and repair shops MAKE MONEY off repairs. if they repair your car, they make the money for the repair, and the smog. as the name states, test only shops dont fix cars. we give the test, you take care of it yourself. test and repairs will test the car, and are allowed to fix it (if you want them to).

on being sent to test only:
california has this thing called "high emitter profile" that sends a "random" 15% of people to a test only shop for no reaason. simple as that. besides that, if your car is salvaged or a gross polluter, california sends you to test only every time, every year.

the obd2 check is a functional check. it checks to see if the monitors are complete (all but 2 must be complete in all 96 and newer vehicles) it checks to see if a dtc is in the ECU (automatic fail, no exceptions) and for an RPM signal during the smog test. i know someone is going to ask, so no, you cannot just reset the check engine light. the smog machine hooks up into the ecu, and will automatically fail you because the monitors are not complete. so to pass the obd functional, you should be able to read rpm from your diagnostic connector, all but 2 monitors must be set to "ready", and you must not have a check engine light/dtc

question 2. What would it take to pass a ls1 in a s14? The car would have two cats, two mufflers, and be quiet. It would also be running the stock ecu/pcm and all factory vacume lines will connected. Engine will also be newer than the chasis. Any other rules to get it to pass?
rumor had that awhile back, that california laid off the refs, couldnt pay them, whatever. i dont know if thats true or not.

as for question 2
read appendix E of the smog check guide.
http://www.bar.ca.gov/80_BARResource...heck_Guide.pdf

if you are going to bother making this swap legit, i would try and talk to a referee so you can find out exactly what you need to do. once again, he is pretty much the final authority smogwise.

last time i checked, smog checks didnt get x-ray vision when we got our license. we dont know what we cant see, and assume all internals are stock unless the customer informs us. so, if your car passes with the old cams, and you dont rat yourself out, it is what it is. but if you wanna get technical, they are older parts from an older engine, therefore older model emissions components, and technically fails.

nox is increased when:
cylinder temperatures are too high (carbon, motor running hot)
ignition timing is too advanced (base timing or timing advance)
defective egr (not just the valve, the vacuum sources clogged, etc)
lean fuel mixture (low fuel pressure, vacuum leaks, shitty injectors, bad fuel pressure regulator)
if all the above is perfect, check the catalytic convertor. (more than once before you get a new one, these shits are expensive, and dont go bad for no reason, no matter what the shady smog guy tells you)

theres a somewhat common problem with accord 4 cylinders. the egr ports get clogged with carbon. theres a technical service bulletin on it somewhere if you can find it

I just failed my smog 3 mins ago, im on my laptop using his Wi-Fi, he seems pretty mad cause its pass or dont pay, =\ but yeah heres the results, the HC for 15mph was measured at 132 and maximum allowed was 118, my NOx at 15 was measured at 1556 and maximum allowed is 799. I had no problem for HC at the 25mph test but the NOx was still high measured at 806, and max allowed is 738, the guy said I should check my CAT...

what do you guys think..

its a stock KA24DE with straight pipe...

let me know if u need my other numbers

I just failed smog and need help cause re registration is coming up in a few weeks and i would like to be able to drive my car. Any help would be great. Here is my numbers. I failed for high CO and high NO

CO Max is: 0.75 and i measured 1.10 for it
NO Max is: 799 and i measured 1993 for it

when i bought the car about 1 1/2 years ago it pass smog with no problems... now this.
The smog guy said i probably need a new cat, but if there is a way i can get my numbers down with out having to dig deep in my wallet for a California legal cat that would be great. I hear seafoam i hear changing the O2 sensor, spark plugs ect ect and i was wondering what you think


Thanks

I had no problem for HC at the 25mph test but the NOx was still high measured at 806, and max allowed is 738, the guy said I should check my CAT...

what do you guys think..

its a stock KA24DE with straight pipe...

let me know if u need my other numbers
if "straight pipe" means no catalytic convertor
you should probably get one. if it means a muffler tip, read on.

easy stuff first. timing, check for vacuum leaks, fouled plugs, wires, obvious shit.
high HC and NOx sometimes mean a misfire. check how much o2 is coming out at the 15mph. if it is high, there is unburned oxygen coming out. check for a misfire. if O2 is low, check the EGR valve, it may be malfunctioning.

NO Max is: 799 and i measured 1993 for it

when i bought the car about 1 1/2 years ago it pass smog with no problems... now this.
The smog guy said i probably need a new cat, but if there is a way i can get my numbers down with out having to dig deep in my wallet for a California legal cat that would be great. I hear seafoam i hear changing the O2 sensor, spark plugs ect ect and i was wondering what you think


Thanks
is this during the 15mph or 25mph?

burned oil, unburned fuel, and lean exhaust fuck catalytic convertors up. they either melt or clog the substrate.

i have seafoamed my 197xxx mile stock KA a number of times. half the time just to see the spy hunter smoke cloud behind me. and it would be just embarrassing if my car didn't pass smog, right?

is hc low?
look for something causing a lean condition, or a lean misfire. you have partially burned fuel (co) coming out, as well as high levels of Nox (high cylinder temps, lean air/fuel mix, advanced timing).
