If they were both same mileage, running stock power etc, same driver all the kind of s**t that's never ever going to happen, 106 GTi would be faster in a straight line, probably around a track too.
Chances are a standard 106 GTi will be quicker off the mark anyway as they're newer cars so haven'tbeen ragged for so long and not so down on power, lighter and have diddy 14" wheels which all help.
