Does anyone here in California have a k24z3 build, and does it pass smog? I've text some shops asking questions about a k24 bottom and smog. Only answer I've gotten is they are high compression and only guys from the Midwest to the east coast but them. Any answer in the right direction will be appreciated

I didn't think about that. I'm looking to do an engine swap. And need all the info I can get
I know this response is a bit late, but per the laws of Comifornia, as long as a motor of a newer year goes in a car, it will pass smog. If you do just the bottom end, you may have to obtain the K24z ECU while you're at it. I don't know if the K20 stock exhaust manifold and cat will play nice with the K24 ECU and intake components though. But, if you are doing a straight up swap, (apples to apples), you're golden.
