Toto Power Gravity to G-Max conversion?

[Maverick]

I've searched for an answer, but haven't found anything yet. I have a Toto Carolina Power Gravity toilet. Can I convert it to a G-Max flush system? If so, what parts are needed? Thanks...

A new toilet! The internal passagways are larger on the G-max. It's more than just the flapper, it's the tank and bowl.
