well you can start with a new air filter i got a K&N, they can be bought at parts america or pep boys they are univeral fit. After that you can get a new exhaust system that will set you back a couple hundred of bucks for a good one, I 2.25" pipes going into a glaspack, loud as hell, but it rumbbles, you can get those at any good muffler shop. they will increase you HP a little but nothing hugh for that your going to need major work or invest in EDGE products. oh yea and hope you have gass money for the Huge HP you wanna add.

well, you can save up and get a nitrous kit thats probably going to be your best bang for your buck, and the newer systems have plenty of saftey features to keep you from blowing your engine up

 

Well,the msd ignition put a little pep in my engine, not much though, throttle body spacer adds noticeable gas mileage but not speed, im about to get a cheap air intake without the heat shield though, I want it more for the sound heh.... and of course don't forget exhaust.

 

75 shot of nitrous, cut-out before cat-'s, UD pullies, intake, traction bars, gears, stall, tuning.

 

How much would it cost to get a nitrous kit installed at a shop?

 

they quoted me $400. thats why i learned to do it myself. its pretty easy compared to building my own turbo set-up. just some wiring and thats about it.

you'll want-
window switch
purge
automatic bottle heater

for accesories.

 

Yeah, I just gotta find a shop around here that does this kind of thing to see what they quote me. Too bad you don't live closer, id pay you to do it.

 

its not bad @ all. are you good with any wrenching. i can help you through it if oyu like.

 

Yeah, its more I don't trust myself or if I do something wrong im gonna mess my motor or have leaks or something like that..

 

intake, exhaust, smaller lighter pulleys, better plugs and wires that's about it for the cheap hp gain but to do anything major you're talking paying money, nitrous isn't a bad way to go, but then you have to keep in mind that you have to get refills when it runs out.
