It all depends on where you race from, and the driver. I have a 97 black base model prelude. The prelude low end is a good bit better, but, the integra's high end compensates for it. The prelude will get the gsr up front but the gsr's 3rd gear is crazy. It ususally just depends on the driver. If one gets a bad start the other one will win. If both get good starts, i can't really tell you which one will win. The two cars are very similar.

The gsr is lighter than the prelude but the prelude has a more powerfull engine.

From my experience racing them, I have won many times, and lost many times. It mainly just depends on how well your car is running when you race.

Oh and I race my friends at the track, not on the street.
