The weak link is the automatic transmission.
More than about 200 crank hp will sorely test it's ability to shed heat and put down power. I've yet to hear of a solution that makes the Integra auto trans a reliable component in dealing with high horsepower.

Two options:
a) Convert to a manual transmission, assuming the laws in Illinois allow it. (Check.)
b) Save up for a manual trans Integra LS.
