The Z1 is made for increased fuel economy, assuming you have the proper matching ECU.

Considering it's a frankenstein steup...there's no 100% way for us to tell you, but I would guess in the low to mid 30's. Maybe high 30's if it's well maintained and properly driven. Bone stock and in perfect running order, the VX is rated 39 city, 49 highway.
