any b-series swap is going to require basically the same amount of work. its an engine swap, its work. but if your looking for a good deal on motors and are willing to wait for a while to get it... flashoptions.com. its a pretty smalltime operation, but ive gotten 4 motors from them and they were great. back to your question, all the b's require new mounts and computers/wiring harness. if youve never done it before, dont worry, its a honda. kinda like legos, but bigger.
