Adding a turbo to a car and not changing gearing or going to a smaller motor is not going to help anything but acceleration really. Kind of a similar problem of doing aero mods and not changing gearing. The engine load decreases but the rpms are high enough you are still using a lot more gas than you really need to.

"or going to a smaller motor"
that i would like to see, two engines same power, one NA, and one turbo'd.
that would be interesting, OK who wants to do it?
PS. power and economy are usually inverse.
