I find that hard to believe. I can't see the T56 being lighter than the Honda transmission. I also can't see the aluminum V8 being lighter than an aluminum 4cyl.

You're obviously ignorant when it comes to V8s. I got 28-32mpg on my heads/cam Z06. Granted, this was taking it easy on the car, but it's very tame when you want it to be.

LSXs are aluminum block/heads.
