the stock 5 speed EXs aren't too bad from the factory, eh, 16.5ish in the quarter with a semi-descent driver. I imagine with a few polishing mods like i/h/e, and a small shot of nitrous you'd be doing quite well with those cars. Just don't get your hopes up if you descide to go with only i/h/e....while it'll gain you power, not really anything that exciting.
