well, she's a professional racer so we'll probably never know what her engine truly has/is made out of. but i suppose that they probably spend a lot of their time tuning it so it can run like that.
and the quickest from my civic, 13's with nitrous with the factory civ ex motor. i'm gonna learn a bit more about the h22 swap and maybe look into that into the future and hope that the skies the limit, both in terms of parts and money.
the quickest professional i've seen in a civ is 8's, but i think he'll probably be breakin 7's soon, or i at least hope to see it soon

the fastest civ i've seen run on street's, a vid clip of jason's h/b, haha.
