First thing to put in

i agree with oc. and another thing, if you want a fast car. you could 1. try and make a slow car faster by dumping countless hours and money into it. OR

2. buy a car that is already fast (dodge stealth RT TT, 3000gt TT, *basically the same car* or something to that extent that wont cost an arm and a leg. ebay motors has some outstanding deals on some 3000gt's for about 10,000 and under. and by the way, the 3000gt twin turbos have about 310 horsepower stock. any other add-on you put in the car will actually ADD a noticeable amount of horsepower. not that you need it in that car...
