Congrats on your purchase. I have the same exact model accord. Does you automatic transmission slip at all. Mine was a piece of junk and than I found a recall on them. You might be able to still cash in on that recall. But, As said, a 5spd swap would be the ticket. I'm happy I did. Some minor gains can be brough by doing a bunch of small stuff.
After I got my intake, head, exhaust, new irdium spark plugs, new spark plug cables, and had it tuned, I gained about 21hp! No joke. Also, change the oil, get the injectors cleaned, and get all your fluids flushed and replaced. It really is just a good thing to do to your new baby.
