How many of you Kalifornyan's with 24v e30's are smog legal?

[cmybimmer]

Damn, it took 45 mins to inspect it?

And im planning on going to solano cc in fairfield...

[Yeee30]

it took me 45 mins, it took my friend a good 20 mins, it all depends where u go.

Have the BAR appt Monday... Anyone have any problems with a k&n cone or do you think I need to make some janky airbox setup? lol

[reelizmpro]

Somebody isn't grasping the concept.

OBD exempt? Did you make that up?

You need to wire a check engine light.

LOL, M3's and ETA's are OBD exempt because they don't have check engine lights. Idiot smog techs will often fail M3's because the old books say they should have them but they in fact never did. If you put in an M50, then you'll need one to wire one up.

[rlddlr53]

the m3 is long gone, the car I am trying to get the sticker for is a 89 325i coupe with an s50. Just had e36 cats welded in. Only thing I think they may fail me for is the k&n cat., but I do not have the carb sticker. I was thinking about creating a carb sticker with the correct carb# for the intake I have off k&n's site and putting it on lol

Congrats, how hard was it for you?

It actually wasn't too bad at all.. I passed visual since my first appointment, but failed emissions two times.. was trying to get away with not replacing my cats to pass, but no dice.. replaced the cats with a magnaflow universal cat, made an appointment and all was well :up:..

Feels good to have a street legal car now!

[ninety4e36]

I haz no catz

[blackhawkimpact]

Bumping thread. I'm about to see if I can get the car BAR'd and sniffed since my plates are due. I'm running with no cats right now and was wondering what you people that pass BAR were running for cats. I'm looking into buying the Magnaflow universal cat 46004. It's a direct fit for the 95 BMW M3. Will this cat be ok?

I'm using (2) of the Walker 80301 cats.

Cool thanks. I'll check the price on those

Alright ladies and gentlemen, I'm coming to you for help on this one. I am nearly there in terms of having a BAR'd swap and wanted your opinion and expertise as to what I need to do to turn this frustrating corner.

In 2011, I went to the CA Referee with a stock obd1 m52 running a red label 413 ecu. Nothing was done to the engine except a lower temp thermostat I believe. I was running obd2 exhaust manifolds, obd1 e36 m3 midpipe to stromung catback exhaust. Nothing crazy. Here is the smog attempt for that day.



After this test, I didn't try to have the car BAR tested for a while. In between the last test and the upcoming SMOG test that you will see in a second, the following modifications were made:
-S50 Cams
-TRM M52/S50 Cams Tune
-Timing was corrected (It was off by a few degrees according to Chris Castro)
-Exhaust was modified after the manifolds but before the CATs for corrected exhaust flow
-New Radiator
-I can't recall what else I have done since then to modify the engine to increase power output.
-All maintenance was taken care of (spark plugs, fuel filter, oil, oil filter, air filter, etc)

Here are the results for this SMOG test that happens roughly 2 weeks ago:



My emissions scores got SIGNIFICANTLY WORSE. What happened? I immediately called Chris Castro and promptly stopped by for a new set of replacements CATS, new fuel filter, and new throttle boot breather hose. This all happened about a week ago FYI.

I go in today for another crack at the Referee Station and here are the results:



As you can see, I passed the 25mph test on all accounts but the 15 mph test is still bad. NO readings dropped about 300ppm from 2 weeks ago's SMOG attempt but it is still three times the accepted amount, putting me in the Gross Polluter category. The engine runs fine honestly but there is clearly something wrong for me to fail.

I understand NO is typically produced when the engine combustion chambers exceed 2500 degrees F and a culprit of this would be running too lean (more air is entering the combustion chamber than gas, causing an imbalanced combustion, leading to high NO). HC is also too high but not by much.

I heavily appreciate any input on what could be the cause of this and the fix to this problem as well.


Also, the engine is being tested as a 1995 m3.


Thank you for reading and thank you again for any response that may lead me to the fixing of my little problem. I am so close!

[cmybimmer]

Wholy cow! Uhmm yeah definitely a gross polluter you got there =/

Crazy how the new cat barely dropped the numbers.. Could it be the tune maybe? Just a guess, I made sure to BAR my shit as stock as possible. Sucks that you didn't try again after your first attempt.

Good luck man!

just scheduled a appointment for next friday :up:
