i was looking for a new engine it has a d15b2 that blew up so time for a new engine. its a 91 civic dx hatch. i was looking at a b18b swap is that a good engine will it fit how hard wood it be and what do i have to change to get it in and running. thanks

 

first off the 91 dx has dpfi (dual point fuel injection) meaning it only has a 2 fuel injector system, so the first thing you will need to do is rewire and convert the car into mpfi so you can run a 4 fuel injector engine, there is tons of help on this subject
look up dpfi to mpfi swap. now to swap in a b series into a d series car you will need engine, trans, axles, harness, ecu, shift linkages, motor mounts
