    So I've been fishing around and wondering about the conversion. Is it benificial for an 02 gt to get this done? Worth it? What to expect if can be done as in power difference?

    If this is just on a stock 2002 GT, I wouldn't do it.

    Expect atleast a ~30% loss in fuel mileage, do to E85 needing ~30% more fuel to make everything happy. Without making huge power, this change over is pretty much useless.

    switching to E85 is only beneficial for boosted cars and trucks. the gains on a naturally aspirated vehicle are negligible.

    If you don't give a s*** about the oxides of nitrogen emissions you could run it lean as f*** without detonation and probably about Break Even on fuel economy per dollar
