5-10 years ago fuel systems were made with rubber seals and diaphrams that couldn't handle alcohol now a days 99% of all vehicles are compatable with it.

OF COURSE THE MANUAL SAYS NOT TO USE IT, it will not work without at least a reflash and since reflashes aren't covered by nissan it basically just a liabilty notice just like a tdi manual telling you not to put gas in it(no-brainer) a stock car will not run on e85. our engines relatively high CR of 11:1 makes it a great candidate for e85 especially considering the sophisticated anti knock logic nissan had to use there is room on the table for e85. as to the injectors, maybe in a stock motor you could get away with it just check your duty cycle and see if there is room to go maybe gtm could tell you on that.

also there are all aluminum flex fuel motors with no special coatings, this is actually the norm. Also there are no e85 motors i know of that are running 18:1 base CR. Thats crazy almost diesel territory. turbo applications may have an 18:1 dynamic ratio (adding in boost pressure over base), but most n/a e85 engines are flex fuel meaning they are in the 10-12:1 range static cr because they still have to work on gas. e85 is all about timing advance and running pig rich on it for na power, emission state guys love it because its harder than hell to fail a sniffer on e85
