what should i do?!?! plz help

Read, buy, install....
But seriously, what is your goal? Looks, Drag, AutoX, all of the above (and if so, what is most important to you?) You've got to build the Stang that you want, not that everybody else wants.
For starters, full exhaust, including long tube headers (BBK's are nice), mid pipe, catback=about 25 RWHP. And add 4.10s or 4.30s, a tune, K&N filter, pulleys and you'll be having fun...ENJOY!

well, IMO you should leave off the body kit. I would focus on performance first, just my opinion of course. Some great mods that will make your car handle better and perform better are 4.10 or 4.30 gears, chip, cams, long tube headers, jerry mod, tranny cooler, PI stallion torque coverter, o/r midpipe, catback of ur choice, subframes, upper/lower control arms, springs, drag radials, etc....

or just save for a s/c or nitrous. If i were i your shoes, and had that money to spend, i would focus on the tranny and rear end. 4.10s, jerry mod, tranny cooler, and torque converter. That will really wake the slushbox auto up then, i would use the left over for exhaust or start on the suspension mods and then save for the cams
