First we have a guys who wants speed, so he narrows his cars down to an Integra GSR or Prelude??

So here are some head to head comparison numbers from C&D and SCC(same conditions, standard testing technique); unless you want to base ur decision on all street racing stories:

C&D:
Prelude 1/4mile: 15.4
GSR:15.7
Prelude Lap time:1:22.3
GSR lap time:123.4

SCC
Prelude SH 1/4mile:15.5
GSR 1/4mile:15.7
Prelude SH lap time: 1:12.49
GSR lap time: 1:13.90

So ya, the GSR owns the Lude...
