Not sure how crediable this is but Auto Express mention the next gen NSX's HP output to be 450HP with a similiar 3.6L V6.
Seems like just another rumor, but a sweet sounding one at that.
"Meanwhile, sources in Japan have revealed that the next-generation NSX, which is due for launch in late 2005, will be powered by a mighty 3.6-litre 450bhp version of the current model's V6 powerplant."
