power means very little in most autocross classes. Case in point: My car is a '92 VX. For those of you unfamiliar with this model, that means its ass slow (92 hp). Yet I have managed a number of 3rd place finishes and a 2nd place finish in H-stock (which is where most civics would end up in stock form). After I got my GC and konis, I got a pretty respectable finish (5th or 6th--i don't remember) in STS against cars like gs-Rs and the like (e.i. double my horsepower). Really all you need for autocross is good tires and good driving skills, power has very little to do with it until you get into mod classes and so on.
