Title: Pontiac Firefly Post by: 2ML67 on February 27, 2006, 12:42:11 pm A friend of mine just finished redoing the body and paint on his girl friend's convertible Firefly. The motor has a lot of miles on it so we are looking into a swap for it. Now big decision got it down to two possible engines either a 4 cyl eco-tech or a nice 3800SC series II. The car is a standard tranny car and will remain that way just need to decide on which way to go all out racer or reliable slightly faster compact. Opinions appreciated. Dan

The 4 cyl 140+hp eco-tech would give you almost 3x power increase. A 3800 series 11 is a lot heaver for the 1600 lbs car and would have to be wedged in to the tight engine compartment and with the 5x power increase would be a handfull. Guys have been putting in the 180-300 hp Hayabusa engine and no problem with space. Bottom line --- I would have to side with the eco-tec.
