But the question is, "Does this guy know what hes talking about and what does his car have?" Remember that the Civics are super light and highly modifiable.
MOST people that race Civics don't know what they are doing, or only can afford an exhaust can and maybe an intake/header, that's it. But there are Civics out there running K Series engine swaps complete with internals, turbo, and the works. This are the ones to watch out for, but MOST Civics are super slow.
