Well to start a Cold air intake and full exhaust will give you the most power for your money, and to got futher a chip for your computer or a reprogram. As for astetics a lip kit w\ some adr 17" rims w\ kumho ecsta supra tires. All together under a grand and pick up a substancial amount of ponys as well as eye apeal

First- don't expect large power gains unless you go forced induction- which in the case of the TSX is most likely a supercharger. Comptech is your best bet if you choose to go this route and you'll pick up an easy 60-70hp.However going FI is pricey and will void your factory powetrain warranty. For most owners, sticking to bolt-on modifications like an intake and exhaust are your best bet for mild power gains at a reasonable cost wihle maintainig your factory warranty. Best bang for your buck is a cold-air intake- Comptech, AEM, K&N, and Injen are just some of your choices and you'll pick up 5-7hp. Personally I'd stick with a Comptech intake as you get the benefits of a cold air intake without the (small) risk of sucking up water into your engine and having it seize. Next I'd get a Hondata ECU- basically an upgraded engine management chip that raises power across the entire rev-band as well as bumping up the redline. The engine in the TSX has a lot of potential and the Hondata ECU gains you some of that potential- you can expect 7-10 hp.Next would be exhaust and headers- but these start to get expensive ($700-1000) each and the gains are smaller (3-4 hp).The TSX has a great suspension from the factory- a few simple mods will go a long way without reducing the driveability of your car.First if you're an agressive driver, upgrade your tires. The all-season tires perform poorly in both dry and wet. The only good thing about them is that they will last forever (30K+ miles).If you live on the west coast or south where you never get any snow, you can get ultra high performance tires like the Bridgestone S-03, Kuhmo MX, or Michelin Pilot PS2 which will grip tremendously in the dry and give your great wet grip. However, these tires wear very fast (15K miles) and cannot be driven in the slightest bit of snow. By themselves, these tires will completely change the handling of your car.However, there are also great high performance tires which wear slower at the expense of some dry grip- though still a great improvement over the stock tires.Honestly- besides possibly upgrading your brake pads to more agressive compounds (the factory pads are little better than cardboard)- there is little more you need to do to your TSX to have a great handling sedan which will be great fun on any twisty road.
