alright some of you guys might find this as a way to open ended question but im new to cars i've always been into bikes i've got a ninja zx-6 but i just bought a blk cobalt SS/SC 2 days ago and now that i got it seems like everyone has one of these things all i want to do to outside is change the head lights and put on some LSD hinges other then that i want to put about 2-4 grand in the engine how far or what stage could i get to by spending that much? what should I do to the engine to ge this thing to jump off the line and through the gears quicker?

i'd really like everyone to send me some ideas either on this or 2 my email
