i think they actually have a nice flat torque band.

edit it looks like those are all f/i setups
go to jeff evans dyno pages and search for c series nsx under engine type. its interesting to see the numbers that all the different cars and setups that he tunes put down.
id love to buy an nsx and probably will some day but stock i think they run like mid 13’s at around 105. not enough for a car like that especially since every fool will try and line up wit you.
