Mogami, found this in the March 2012 issue of Road & Track:
”Our sources in Japan say that the future NSX will be powered by a 310 HP 3.5L V6 gas engine and two electric motors
good for an additional 100HP, for a total of 410 HP...it’s rumored to hit 60 in 3.0 sec.”
There’s the SOHC J35 and RLX setup you were referring to (388HP reality vs a 410HP rumor back then)...
Well they basically hit their 0-60 target.
