I have a 97 Honda Civic hx and my d16y7 motor blew in the second cylinder. I got a d15b2 for super cheap and have been running into some difficulties. I know some of my woring won’t fit but mainly I can’t figure out the distributor. The one from my old motor won’t fit into the d16b2 but if I leave that d16b2 distributor then my wiring won’t plug in. What do I do?

That's going to depend on how the engine blew. Spun bearing or bent rod could leave the head untouched. Burnt/bent valve, broken con rod, over-revved, chunked piston and other situations could leave the head in bad shape. This sounds like a more-time-than-money situation, so tools to replace a burnt/bent valve might be out. Hell, even a replacement head gasket could be out.
The Y7 distributor should fit. IIRC, it's just the 5th gen VTEC distributors ('92-95 EX/Si/VX in the US) that have a different bolt pattern. Everything should bolt up fine except the driver's engine mount (needs the timing belt cover modified) and maybe the power steering pump bracket? No PS on my CRX, so I dunno. The B2 radiator fan switch is on the back of the block instead of the thermostat - run wires or maybe swap the thermostat housing. Maybe even just swap the housing cover. I'm not sure exactly what fits what so take a close look at it before pulling things apart. If you swap, get a new o-ring or two for the black metal water pump tube. The old ring(s) will leak if you pull the tube out at either end (the thermostat housing is one end).
