Message	I am going to upgrade my fuel system for e85 while I have the motor out for repair. I am getting conflicting advice from various sources on how to upgrade my fuel system ranging from "just get some 740cc NISMOs", to "upgrade your fuel pump and get 2000 cc injectors." What do you guys think? Fresh stock rebuild with forged pistons. Sport 500 turbos Breather Mods Full 3" turbo back
