i just happened upon your post on your own profile. lol. but the best upgrade for power would be to get a 6spd swap from either a acura cl-s, tl-s, or 7thgen accord. you can also get a comptech s/c fr some real power. that'll all cost you a pretty penny though. but heck, it'll make for a power *** car. you can also get the basic's i/h/e/p.
