If Dinan couldn't get an CARB approval for it, then there's little hope.
1) Register the car in a California county that does not require smog checks. Yest these places exist, and all you really need is a P.O. Box in that county.
2) Register the car in an other state, and drive the car here hoping the CHP or any police doesn't give you crap about the car's plates and registration. I believe out of state cars legally can't be in the state longer than some specified amount of time.
