My point was that there are options to speed up the NSX to modern day expectations. A CTSC for $10k will help, and there are plenty of folks with turbo'ed NSXs at 450-475 crank hp, which should be about the same as a Z06 at the wheels. Reliability may suffer with a turbo, but the Z06 isn't built as well either (and it remains to be seen how long that supercharger/motor lasts on the 'vette).
That being said, if top performance was my goal, I'd still get the Z06 for factory-set ease of use.
The C6-z06 is normally aspirated, not factory supercharged. At this point its a 7 liter small block 8 making an honest 505hp at the crank. Its not a POS either (as many like to say), with titanium rods, aluminum castings, 7k RPM redline and a dry sump system. Ive seen stock Z06's (BONE stock) get into the 11's on a drag strip with competent drivers and traction. Its 3132 lbs also and has brakes better than a 996 TT (which are a lot better than the NSX)
I LOVE the NSX and Im not a big Vette fan (owned one), but the >C6< Z06 is a world killing titan. The Ferrari F430 and the Gallardo get embarassed by it in many absolute numbers tests. Dodge upped the 08 Viper to 600hp because of it.
You're just not going to take an NSX with its essentially 20 year old design that never truly evolved, as BRILLIANT as that design was, and compete with the absolute EDGE of modern performance by pushing it through the tuner market.
The C5 Z06, possibly, since the C5 Z06 was a far lesser beast (although I still think it would take a HELL of an NSX to match one in *pure* numbers), but a C6 Z06 it just isnt happening.
Now consider that Vipers and Z06's have supercharger kits too and they're all a lot easier. And those motors are ENORMOUS and can take the power with zero effort and no dependibility hit AT ALL. Supercharged Vipers make an extra 100hp and dont breathe hard.
Dont mean to belabor the point, but I think the OP should go in with eyes open. The NSX is NOT the place to look for PURE POWER. You'll spend far too much, end up with too little, and in the end be sort of nullifying the BEST quality of the NSX which is that it was the gentlements exotic - the look and manners of a Ferrari with the soul of a Honda (both good and bad - the good being that it is rock solid, not tempermental and as reliable as a civic)
=============================================================================================================
EDIT: And my suspicions were correct! To the OP: forget it... If you are after neck snapping acceleration and the feeling of massive torque, forget the NSX. DO NOT buy an NSX and embark on some crazy project to try to turn it into a drag queen or a Supra. If you do go the C6 Z06 route though, PLEASE be careful. It seems people that want to feel their head thrown back are totaling Z06's and Vipers in numbers lately that are going to get those cars banned and they are taking innocent people out with them!
The NSX is a corner carver. It lives in the high revs and on a track it will reward you with its perfectly balanced suspension, amazingly neutral steering, excellent mid-engine weight distribution and setup, driver friendly position, and great gearbox. It was called "too easy" by the pompous Euro mags back in the day even as it matched lap times with the likes of a Lotus Esprit and Ferrari F355.
But it has no torque and no off the line acceleration in modern terms. The Viper and Z06 are high 3 second 0-60 low 11 sec quarter mile cars. The NSX in its absolute fastest domestic incarnation is POSSIBLY as quick as a C5 Vette, but again, that isnt even the point. A midengine track super car is just NOT supposed to be a fire breathing torque monster. The Lotus Esprit and F355 arent either. That role is made for muscle cars like the Vette and Viper (which, interestingly enough are also good on the track).
The best of ALL of these worlds is almost certainly the 911TT (although having owned the 911, I cant help but find it a bit boring b/c of the styling and ubiquity of them no matter how hard I try)
