Having owned both it would be much closer than you think in a straight up drag as both have identical power to weight ratios.
I'd say it would be down to driver skill levels TBH, off the line clutch control, reaction time, gear changes etc...if both standard that is. Comparing modded cars is just pointless!
Power runs are pointless as well, as the ep3 comes with more power from factory and your 2zz is standard so save your money there straight away.
