worst set up for a Z u can do. Poor milage, crappola power.

Good point !! Thanks !!


I always got decent milage out of the Dual SU's 20-25mpg. Custom EFI system (Change the head, computer, fuel rail , fuel pump, injectors, coil pack ) Pretty involved job, but will get you a few more MPG. SDS makes a really good EFI system.


sorry, that answer was SU OR custom EFI
