Welcome!

General rule of thumb is what ever goes in, must come out.

So adding a better air intake would be a good start.

Many prefer a fender well intake (FWI) over anything else. You can usually make these yourself for next to nothing. Or you can buy them already made for you if you have the funds.

Maybe a set of new plugs, one heat range colder. Many run the AutoLite brand, or NGK's.

A down pipe is one restrictive thing on our cars, the I.D. of the pipe is quite narrow, so by adding a 3" down pipe, or even a set of headers...you would be golden. Lets not forget the ever popular "U-bend" thats the exhaust pipe for the second 02 sensor, and the sensor is mounted vertical, which makes the pipe go from round to squashed. You can have any muffler shop cut this out, and mount the 02 on the side and run a fully round pipe.

Pulley size...a 3.4" would be a good starter pulley. If you plan to take your car further...invest in a modular pulley system now, and don't even waste your time and money with a press on one size pulley.

Lots of other things you can also do...rockers, cams...etc. Just depends on your budget, and how far you want to take your car on the mod bug game.

Though, its far from a game, its more like a contagious disease.
