JDM motors are 100% smoggable. B16 in an obd1 car is probably the easiest hybrid to ref next to a B18A/C. One of the major things you're going to need is a USDM P30 ecu and to make sure that all of the sensors are properly working. You're a shoe in once you get your hybrid to the point where you'll pass the visual and functional test, the sniffer test will be easily passed given you've done everything correctly.
