I've done this swap on a d series before and it should roughly cost $700 +/- 100. This mod is cheap in comparison to an engine swap. Provided you're going for a street car you'd need to have it done by a pro if you want any chance of getting it rego'd. For a b series swap which is most common in gli ek civics, it should cost you in the order of $2000 if not more. This mod is fairly straightforward and requires no extra paperwork. In exchange, you get vtec and if paired with some good mods such I/H/E and a tune, you're much better off
