anything pre 2000 is pretty much garbage,(in any type of performance aspect) after that heavy engine modifications were made... AKA the 2.2 and 2.4 ecotec inspired engines. Designed in europe. It is a modern high reving engine. They hold up great and work miracles for your information hollywood.. and the whole it won't make it to 4500 rpm was a lame comment. I am not putting it in the same class as that mustang, but they are good cars.

cionsidering the cobalt uses almost the exact same engine.(smilar mods can be done to the z24 as well)
