"No KLZE will pass emissions" is that true?

Is it possible to have a KLZE get the same emission levels as a regular K8?
In other words, is it possible to have a KLZE pass emissions even if you live in Emissions Anal California?

i have heard its doable, if emissions are a big deal i would just do a DE swap and put in ZE cams and be happy

Most definately and please think before you ask such a question. If ZEs wouldn't pass emisions then how would anyone in Cali. do a swap? There are docuemented cases of ZE swaps in Cali and I think there was a ZE'd MX on here for sale recently that was from California.
However, to answer your question, yes they will pass and yes can pass with better results than a K8. My ZE has passed every year so far with better numbers than my K8 ever did. I bought the MX with 30,000 miles and have done emisions on it every year since I bought it. The ZE has been in the car for about 6 years now and passes with flying numbers. You do see alot of people on the board that have a ZE that fail. They usually fail the first time they try and get the emisions and I would attribute that failure to a lack of repairing old parts on the car. Generally you see high flow cats that don't do their job of burning the expent gasses, poor plugs caps and wires, old O2 sensors, old fuel filters, K8 exhausts on a ZE and other things. What is often overlooked is the fact that the ZE is NOT a K8 and thus shouldn't be treated as one when preparing the car for a ZE.

If you put a ZE in, without any modifications, then your answer is no. A ZE engine will not pass in California. 2 reasons. First, you need to add an egr, for the smog test. Second, you need a smog sticker(to match the engine), you have to have the state's smog referee inspect the engine, to pass. Now, if you can find a smog station to illegally smog your car(meaning smog it without testing the egr and checking off the smog sticker), then you don't have to go to the state's smog referee. So that would be a yes.

A ZE will pass emission. Swap ur EGR setup over from the K8..and hook everything up as normal. And ur ZE will pass all inspections and sniffer in Cali.

it also depends on the testing regulations... up here in the great white north... well at least in ontario... i have the option to test as a 'Hot Rod'... any car that doesn't have the origional motor in it has this option. and the 'hot rod' specs for emmisions are basically twice as much as the stock ones... so its really hard to fail.

Locally, a guy passed w/ a ZE without EGR.. go figure

Same here in California...my friends probe. I had the EGR on there for visual purposes, but it was not functional, and still passed Cali emissions.

I'm in Ontario as well, and I passed as a K8. Apparently Hot Rod specs are getting stricter, while the stock K8's are getting more lenient. Although they wanted documentation saying that it's not stock (cause it's not obvious, even tho my mechanic works there and confirmed it), but they did explain that to me none the less. One thing I may have lucked out was that my car was too low to take a chance on the rollers, or even get up on the ramp, so they only did an idle test.

also from what i have heard by putting a egr setup on the ze will somehow hurt the valves because it is now running "cooler" inert gasses and not the true "exhaust" gasses can anyone else confirm the theory?

I doubt it, the Millenia is the same block/heads and it has EGR.

My ZE passed in Utah, even with two EGRs... It got lower emissions than my K8 ever did. It almost didnt pass because it was idling too high, but I just turned on the rear defroster and the rpms dropped.
