Just to add my 2 cents to the fray: thanks for the post Snakey and good luck with your Viper. I'm sorry your NSX experience wasn't was good as many of ours.
As Tim mentioned, having an engine blow up regardless of the circumstances or who is to blame would sour any ownership experience. I'm just dissapointed Snakey never investigated the many excellent FI options out there for the car like Lovefab, Wil (Angus) and SOS. Any one of these folks could set you up with a NSX that will destroy a stock Viper. The Honda C3X engine is a robust platfrom- Super GT NSXs used this engine to produce 500+ hp under race conditions. So, if you really want it, the NSX can be made as fast as any "modern" supercar. Personally, I don't think Snakey was ever that enthralled with the NSX in the first place. Most of his posts that I recall were always comparing the NSX to his Vipers.
These "comparo" threads in general bother me, as there is very little utility in bench racing these cars against each other. So much of a sports car experience to me is the intangible stuff. Some cars just feel "right" and others, though they may be superior on paper, don't. For example, I am this way about Porsches (sorry, Tim). I can't stand 'em. I know they are super fast, I know they have a great heritage and I know that they are raced all over the world in GT classes high and low. But, they don't feel right to me. I have driven 924, 944, 993, 996 and 997 P-cars and they all feel wrong. I don't like the gearbox, I don't like the pedals, I don't like the steering feel and the engine in the 911 models is in the wrong place. Notice how none of these complaints mentioned comparing dyno charts or nebulous 0-60 times from some magazine test. Instead, I just don't like 'em. This is such a personal feeling, that comparing cars doesn't really get us anywhere because different people like different intangibles. I'm sure there are plenty of folks out there that think a 993 Turbo Porsche (my teenage dream car btw until I actually drove one lol) is the best sports car ever!
So, when I see threads like "Which is better, NSX or Viper?" I roll my eyes. Nobody can tell you the answer to that question because nobody else is you. Clearly, Snakey always liked his Viper more than his NSX- it just means the Viper's intangibles were better for him. In truth, it would have been a mistake for him to spend $15k on a 700hp Lovefab turbo setup, since all he would be doing is trying to make his NSX into a Viper. Better to just get the Viper. I have driven a Viper and I think it's a brute and a handful. That sort of stuff gets real old real fast for me and the thought of driving that car for more than 30 minutes makes me shudder. On the other hand, I feel that my NSX gives me the best driving experience out of any car I've been exposed to. It is sedate enough to tool around town and, if driven properly it can deliver more thrill than I can manage at my present level of driving skill. Plus, all of the other intangibles that make NSXs popular despite being "slow."
