for the 180 hp finishing point, you have the options that daox gave you with those price ranges, or you could swap the 1.8 ecotec out of the cruze (ecu and long block) and get 140 hp, and then get a tuner chip and end up with @ 150-155 hp for less than 2 grand. OR spend the 2-3 grand on a 1.4t swap out of a cruze, and tune that, (trifecta has @ 190hp out of one with just a tune).
that includes your own labor.
