    I have a 91 crx hf with a sohc zc engine in it and the smog places keep telling me that i have to out an egr valve on it. But the zc wasnt made with an egr valve so to deo this i would have to put the hf intake manifold on it anyways and then it probably still wont pass. what should i do ? thanks

    if you put the HF intake maifold on, it will probably pass, most smog shops are not going to know whether what the difference between and HF and ZC with an HF or Si intake manifold on it. The only way they would be able to tell is the valve cover. One says 8 valve (or is it 12?) and the other says 16. The truth of the matter is that the ZC is an illegal swap in california, and there is no real way to get it to pass. So try putting a hf intake manifold on it and see ifyou pass that might just do the trick.
    Good Luck.

    nope they are both illegal, there is no USDM equivallent that can be used for the ZC, even though we all know that it is super similar to the d16a6.

    I am a cali guy, and I am trying to play by the rules, or at least till I pass the smog ref. Then It is play time, by upping the compression and switching out the cams, and valvetrain. I will be swaping in an OBD1 b16 into my 89dx hatch very soon. And I will be installing all the 94 del sol vtec smog equipment. There are some good links in the FAQ on this site about passing smog in Ca.

    A b16 is a legal swap, however there is no USDM ZC. Yes there are motors that are similar to a ZC the D16A1, the D16A6, and the D16A9. However they at least say D16 on them. Smog officials, will fail you if you do not pass a visual. I am sure you can pass smog somewhere, whether it be legal or not. The zc SOHC ZC does not look that different than a d16a6, and if that is the motor you previously had, it really should not be that much of a problem assuming you can pass the emissions numbers...

    the ref never gave me a sticker, he handed me a print-out and said that my car passed all tests and was legal to drive on california highways, i dont have a scanner with me, but i will be able to scan the printout tomorrow.
