The type s is nice and comes upgraded.
BUT, may I suggest these:
Very noticeable change in ride- drop it! Buy new coil springs and shocks (Tokico blues or Konicos). Also polyurethane sway bar links AND verify you have a rear sway bar. If not Get one! You will notice a great improvement in handling. Trust me. Want to do one better- Rims, go two steps up- see
www.discounttire.com on how to properly go up in diameter w/o sacrificing the ride quality.
Also, contact unorthodox racing for underpulleys at
www.unorthodoxracing.com. Best bang for the buck. I had them on my acura and she rev'd much nicer. It was a stick. If UR racing does not make them, try the site below, maybe AEM does.
Cold air intake kit- K&N. Platinum tipped spark plugs, thick wires- larger diameter, forget headers and a nice muffler will run you a few bucks.
See what you can dig up in your wallet and look here, I buy from these guys a lot:

MY best suggestion is join a toyota club forum and see what the people there use. They can give you recommendatiosn and advice on making mistakes they have made. I now own an Accord, dropped! and I'm part of 5 forums. It's priceless and you make new friends. Also, when something goes wrong, they own the car too so someone their is likely to know what your problem is.
