As anyone who's ever owned and run a Z32 will know, the Z is always pretty weak off the line but hell to catch on the open freeway. The NSX has a weight and power advantage over an NAZ but once you break the inertia and the momentum's going I don't see why you can't at least keep up with the Acura. My fave highway run involved a lovely summer evening back in '97 with a 928S4, and a Ferrari 348. I had my old Slicktop and the three of us cleared a pack of "commoners" and gunned it. We all were holding together at nearly 140 mph for over 3 minutes until the Ferrari (fearing for his insurance rate I think) let off and dropped back, followed by the porsche and then myself. Man, the adrenaline was pumping so hard I couldn't feel my legs. Heh, that was before the wife and kid came along...
