get a cheap ebay cold air intake

that chip thing on ebay isnt a "chip". its a transistor. walk in to radio shack and you can get 10 of them for $.99. it plugs into your iat sensor on your car. i've been there, done that. it does add a couple horses if you don't have a cold air intake. if you do it doesn't do anything.

300zx fuel filter is a nice maintenance upgrade. keep your car nicely maintained and it will always run faster.

get an electric fan and pull out your mechanical fan. costs $60 and a couple hours installing it in.

remove the ypipe in your stock intake system. sounds just like an intake too.

get iridium spark plugs and new spark plug wires

shortshifter

straight flow muffler

that's about it. when all that is done go get a job.
