Flywheel lightening is a standard mod in racing and it translates to better FE. I did it on my VW bug and the thing revved up MUCH quicker and gave a seat of the pants acceleration increase.

It's similar to reducing the weight of your rims but more effective because of the gearing. Rotational mass reduction in the drivetrain is usually a good thing. I can never remember the ratio but one pound of rotational mass is worth several static pounds. If you are a good stickshift driver, you won't notice much difference in a manual. Idle may be a bit more lumpy though.
