I would like to start upgrading my car a little at a time. Not really mechanically inclined, but catch on fast. I current have my 2003 honda dx in the shop for a engine swap, going to a v tec. But what could I do myself that would be fairly easy to grasp ahold of and increase the performance of my honda? I have seen a good place to start is exhaust and cold air intake. Is this accurate? thanks in advance.
