hey im just wondering if i can run e85 fuel in my standard 04 ba xr8, ive heard lots about upgrading fuel lines and all that, but im still not sure, does anyone know if i can run it?

You will need to upgrade your injectors as well as you fuel pump and possibly your fuel reg.

Fuel lines etc should be fine.

You will also need at tune to run E85 as well, probably Xcal3 or 4.
