motorswap for 95 civic coupe

i just got a b16a1 in my 92 teg and i love it but I want something more for my civic. i was considering the b18c1 or the b16b. I can get these two for considerably less than the itr. how difficult would it be to obtain parts for th ctr? and would it be alot more expensive to get them because they would be jdm? what would you guys suggest?

I hope someone will respond.Id like to hear what people have to say.
I have a 98 honda civ. and I am looking into a engine swap myself.
