if you want to get a b16, just make sure it's obd1. That will be the cleanest and easiest way to swap it in. If you can get a complete swap from a unkyard or import engine supplier, make sure you get the complete swap with ecu, mounts, shift linkage, axles, etc. It will all bolt directly in. The only difference will be that your map sensor is on the firewall as opposed to the TB on the B series.
