from wut i knoe CA is the stricktess state with emission laws,dohcvtec_accord swapped that engine into that car, and he pulled it off in colorado where there are emissions regulations, so you might talk to him about it. I don't know if cali is stricter than colorado though. As for doing performance stuff to the f22b1, as long as its a stick, you can get some more power out of it, but if it's an auto then definitely do the swap. Intake and exhaust can only do so much for the f22 compared to a factory difference of 55+hp out of the H series engines. And as I understand it, the main thing you'll be fighting with that f22b1 is the sohc, vs. the twin cams in the h22a.
