-- Posted by Ashley Amazing at 2:05 pm on Aug. 1, 2008 What is different about a 2.2 compared to a 3.9? Obviously one is bigger but if one fast? More power? -- Posted by Chevy Jackson at 2:09 pm on Aug. 1, 2008 I'm pretty sure a bigger engine means more power, but also less gas milage. I'm not an expert, though, so don't take my word for it. -- Posted by tempoluvver69 at 2:25 pm on Aug. 1, 2008 3.9 will most likely have more power. Can't really say anything else since you didn't say what type of engines they are or what cars you are looking at. -- Posted by Ashley Amazing at 2:27 pm on Aug. 1, 2008 Quote: from tempoluvver69 at 2:25 pm on Aug. 1, 2008 3.9 will most likely have more power.

Is a cougar a decent decently fast car? depends what kind ouf cougar we're talking.. if we're talking the FWD european designed one, it's okay, if it's an older one, they can be made fast. -- Posted by hinshawwrx at 9:37 pm on Aug. 1, 2008 Not all engines are the same so this is a very very VERY broad question. Like a 2.2L Turbo Diesel will get more mpg  and have more power then a 3.9L gas motor. -- Posted by emo sux69 at 6:03 am on Aug. 8, 2008 Quote: from hinshawwrx at 2:37 pm on Aug. 2, 2008 Not all engines are the same so this is a very very VERY broad question.
