I've got a 92 cavalier 2.4l 4cylinder tops out at like 110-120 im not really sure cuz the spedo stops at 100. is there a gov. in that car? i dont know much about cars really, also im wondering if its worth it to put anything into the car...i want to be able to do 150 160 tops. im not looking for a 9 second car right now, but i do wanna be able to move. ya know? anyway, any input would be much appreciated.
