A stock k20a2 puts down around 200whp. They make power extremely easily, and hold it together pretty reliably. If I were choosing between an si and a v6 camaro, I'd choose the si anyday.

Sidewinder manifold, pte6262, id1000s, rbc intake manifold, kpro, and all the little things that go along with that, and you're looking at 500whp on pump gas. We made 840whp on a friend's stock block on a 67mm, but it threw a rod after some hard passes at the track. Don't let the people here tell you otherwise. You may look cooler in the camaro, that's all opinion, but the fact is, you can go faster in that civic mod for mod.

If you decide to do a roots blower, you could easily run 12's. You can find Jackson racing blowers for as low as $1200-1500. Then all you need is kpro and header back exhaust.

Never seen a modded Civic Si that could hook up. I can't imagine what a 500 rwhp (much less 800+ rwhp) would do with all that power. Sit and spin I imagine.
