@Biffmeistro

Most of the posters with manual transmissions use some sort of coasting with the engine off coasting to help out mileage. I'd be hesitant to do this w/ a turbo because of the same reasons turbo...

I'd also be less inclined to kill the engine at stops or while coasting with a turbo, which takes some of the driver side of FE out of the equation. Not good for gassers imo.
