will not knowing the cali laws on emissions idk if it past. One thing would be call hmotors since there in Cali and ask. The b18B Ls motor will swap into your EK, you need mounts from hasport motor mounts, get an integra shift linkage and shorten it for you model, axles are different. Swap is basic everything is bolt on, harnesses are the same, note if your motor is OBD1 you need to convert your EK OBD1 with a jumper harness at rywire.com if you dont feel sure on the swap seek a local performance shop it shouldnt cost you more then $3000 for the whole thing. Honda-tech.com and e-hatch.com are good forums to get more honda know how
