i almost forgot, the car's an auto, for some reason 2 gear (15-25mph) it appears that i hear a little rattle coming from the front of the car, but then it disappears after it either upshifts or downshifts out of the gear, anyone know what i mean? thanks. the car runs great its just the little rattle that worries me.

Usually people put 62mm TB's on cars with head work (port and polish), cams, boost, a full exhaust, and an intake. A 62mm throttle body probably isn't going to do a stock motor any good without other modifications.

I would recommend starting out modding your exhaust before anything else. Get a header, high flow cat, I would also suggest a resonator unless you like the weed wacker sound, and a nice performance muffler with 2 1/4" mandrel bent pipes. Then maybe move on to a larger TB.
