18k for a b18c civic lol. don't think so man. even if there was one for sale, thats waay overpriced imo

you can easily get b18 eg's under 12k. price depends on quality and other parts. theres a h2b swapped eg for sale atm for 18k.

your looking at around 16-20 for a k20 swapped civic but again price depends on other parts, quality and also what model civic its in.

you'd really need to specify what type of civic your chasing - ie ef, eg, ek, em1?
