It was interesting when I read that with the 276hp Supra, that it was more like 320 horsepower. I have the old game "The Need for Speed SE." None of the new stuff (that my computer can't handle). But the first NFS as a special edition. Anyhow, the game rated the Toyota Supra at 319, maybe 320 horsepower. And the Acura (not Honda in the game) NSX at 276 when GTs 2 and 3 had the American NSX rated at 289 horsepower. Maybe some cars are powerful, but are restricted. Maybe also you can imagine if the JGTC race cars were unleashed from their air restrictions, the McLaren F1 would be a podium contender almost all the time, granted that impressive drivers are racing it.
And call me crazy but, why not take the newer Honda Accords, put in a 260hp motor, and let them loose in touring car, club racing, and of course, the street... and to me, I like the 2-door Accords of now better, even though the lights at the back resemble a Mercedes than a Honda...
