Hi all,
Has anyone fitted the overdrive 5th gear to their ZD30?
My coil cab (CRD) has the standard tires (265) and would like to know if gearing the ZD30 for 2000rpm @ 100kph is feasible. Currently it is geared to do 2500ish @ 100kph according to the GPS.
I do plan to do the usual mods to the engine to fatten up the torque.
My rationale is for touring and aiming to keep fuel consumption down.
I'm aware that there are 3 ratios available, just wondering if its worth it.

cheers

Ralph
