Not all of them. B16A's are availible in OBD-0, I, and II forms.
The conversion isn't difficult. Pick up an OBD-I DOHC VTEC distributor and injectors, reuse your D-series harness and add the VTEC wires. It's not too hard.
The problem is the cable trans that comes on the first gen B16A's. Either sell it for a hydro or buy the proper conversion kit.
