who ever told you all that was lieing to make themselves seem cooler.
Im not saying its impossile. Anything is possible, however, a project car like that would have been known about. someone would have found out something and told everyone. twin supercharged nsx motor in a 350z would be crazy. doable, but crazy
if it was you friend who told you that, feel free to punch him. tell him or her that I told you to.
