Re: e tec.
Everyone will have their own opinion, like Chevy or Ford. They do have quite a list of pros though.
What TD said is correct, and that's just the start. The E-TEC engines use an exclusive low friction design. There are no belts, no chains, no powerhead gears, no cams, and no mechanized oil pumps. That being said, when you consider the fact that the 2-stroke E-TEC produces a power stroke every revolution and it doesn't have the added complexity of all of the belts, camshafts, valves, timing chains and oil pumps that add weight and rob power and torque it's easy to understand why they are said to have more power and performance.
If you are interested in the environment, they are also fairly eco friendly. With their fully stratified combustion system, E-TEC's are designed to comply with 2006 EPA (Environmental Protection Agency and the 2008 CARB (California Air Resource Board) 3-Star emissions rating, and dont smoke.
I would buy one, but have always been Jonnie/Rude biased.
