you mention power to weight, great, but look at a torque curve on both engines, a non turbo builds, peaks and then drops off. a n/a tends to build, hold for a while and slowly drop off. n/a hold torque for longer, turbo's have much shorter but bigger power bands.
then there is grip where torque spikes cause spin.
also an integra is much more aerodynamic, which at the end of the run plays a big part, not so much low down though.
i would be betting on the honda, sorry but the facts speak for themselves really.
