What is Ecomodding?
Welcome to EcoModder.com, an automotive community where performance is judged by fuel economy rather than power and speed. EcoModders employ a combination of vehicle mods, driving techniques, and common sense to squeeze every penny out of the pumps. Reasons for becoming a member range from the economical to the ecological. More info about where EcoModding came from.

When his 1997 Civic CX engine needed a lot of work, turbovr41991 decided to spend his repair time doing something different: he picked up a rusty Civic HX and swapped over the more efficient lean burn engine instead, and went with the more efficient gearing of the Civic VX.
