My Bimmer is stock, so I don't expect a problem with that, but I also have a car with an engine swap (yes, it's a Honda :)

How do I go about getting that car registered? The SMOG check station refused to even test it. They said that I would have to get the stock engine put back in! Which I don't have... Also, he said that couldn't even sell the car in Cali. So... There must be a way around this; otherwise I don't see how cali can be the center of car culture.
