Depends on what you consider cheap. Cobalt SS T/C isn't the best looking but they are fast. A tune alone will get you 300whp. Also the car weighs ~2900lbs. Talk about a sleeper. A tune, bigger I/C and charge piping can get you 36xwhp and 39xwtq. Only downside is FWD. If you aren't a 4 cylinder fan you could always pic up a used 06 GTO with the 6.0. It'll do 0 to 60 in 4.7 seconds.
