Seeing how Japanese tend to be much cheaper than their German competitor in the same class, I would say the NSX would be in the class of the 911 turbo, not the regular 911. Which means 300HP is no where near enough unless the weight is in the low 2000 lbs. This is not considering all the new sport cars coming out w/in the next year or two will be 400+, M3, M5, CTS-V, and etc. Then there are cars like the next GT-R w/ 480+ HP, the next C6 & Z06 w/ 400&500HP, and even the current 911 turbo is already 415HP.
