It would be amazing if the stock fuel system in this car is able to supply the amount of fuel it would take to run completely on E85.
To give you an idea, on my Evo I had to swap the fuel pump from 190lph to 300lph, and the injectors from 550cc to 1250cc, it takes roughly 30% more E85 to get the same energy as it does from pump gas. I know that this is a high pressure fuel system with direct injection, I just don't know if the port injectors will flow enough for a propr idle, and high load, RPM operation.
On a side note if you run E85 your gas mileage will suck, I usually get between 20-25 mpg with pump in the Evo, I'm happy if I get 15mpg with E85, ofcourse my driving habits change quite a bit with alcohol in the tank
