Humm, for some reason I thought all of the axioms had the DI, and that was why they averaged about 3-4 better mpg, and that the 04's were just tweaked to gain some better HP. I had no idea bout the Aisin though. Thanks for the help, I appreciate it.
Yup, just the '04 model but interestingly enough you can also find '04 Rodeos with the DI drivetrain as well.
