So i'm in the process of saving up so I can swap a b18b into my 96 ex. Ive been doing some research and looking everywhere and see a lot of good deals. I noticed it would be cheaper to piece an engine together block and head seperately compared to complete change over. My main concern is will all the b18 blocks work, or do I have to go with just a b18b obd2 block. This is my first honda swap and its on my only car. So i'm going to be without a car for a couple of days and I want this to go as smoothly as possible. I know this swap has been done hundreds of times, but if anyone could help me out and give me a heads up as to any other potential problems i might run into along that would really help.
