You've listed some good points about both cars, however, I think you are more concerned about looks and presence of each cars.
- Supra seats 4-4 1/2 people, NSX seats only 2. Supra is far bigger than the NSX, making it a far more practical car to use.
- Supra is a supercar in its own right, it was part of the Japanese supercar gang of 4 (300zx, Supra, GTO, RX7).
- It is a great track car. May not have had the huge success that the GTRs had, but it was still better than many other cars that were more expensive.
- Handling can always be fixed. Upgrade the suspensions and you will have a car worthy of racing with the big boys (Ferraris etc).
- A FI and an NA of the same car (Toyota did build FI and NA supras) drive differently. For the average driver, It is far more difficult to control a turboed car than an NA. People who knows FI will know what I'm talking about.
If you are a great driver who really understand your car, then FI will always kick arses on the track. NSX may be light and all that, but fast it is not. Even if you add FI, it is no longer the same car and will in fact change the whole characteristics about the car.
I suspect that the driver of the 500++ hp Supra does not know how to track his car properly. He might have upgraded the power, but what about the brakes, suspensions etc etc?
Both are great cars in their own right, however don't be mislead into thinking that the NSX is fast and that the Supra is not a great track car.
