You're forgetting the Novi doesn't come with an IC. Novi & intercooler will cost as much as an IC'ed KB 1.7L. If you get a built motor, then you'll need to upgrade your fuel, suspension, rear end, trans, etc. If you want a reliable 600+hp, it will cost you over $25K in the end. I'm not saying the Novi isn't the way to go; it kicks ass, like any power adder. But you seem to have a false perception that going centri will be much cheaper than positive displacement. It isn't. Horsepower is never cheap.
