People that own NSX's are not buying it for drag racing or with the mindset of "making 1000HP" like Z06 or Supras. Heck a stage III 300ZX TT's with a price tag of $8K will murder a stock 90K NSX when it comes down to racing. But dont forget the NSX still has a higher top end and than the Z. You buy the NSX for class, status quo. Z06's are common everywhere. But hey its your money buy what you like.
