FWIW, I was running 93+meth on my STI. I asked my tuner about E85+meth, and he talked me out of it. From what he said, the E85 is actually a higher octane than 93 with a 50/50 water/meth mix. In effect, I would be lowering the octane of the fuel by adding the meth in. If you're staying with bolt-ons, you would only need a fuel pump and injectors if you plan on running E85. 91 shouldn't need it.
