Think about it, those busa motors make 200hp and have a 14+k redline in a super light car. Hate to say it but that setup would had the vast majority of us our asses in a race. And to top it off you'd be laughed at by everyone and you'd look pretty dumb to boot. I'd do that swap and take it to the track, sure I'd be made fun of until the first race and I destroy the other car. Oh and if I wanted to go faster, they make turbo kit for hayabusa motor that will put out over 500 HP. Just think of how many red faced dipsh!t owners that would get ran over that way. Just have to wonder would they come talk to me in the pit haha.
