    I was E85. Keep in mind that E85 gives poor gas mileage, and E85 prices are through the roof these days.

    Injectors, pump, tune are necessary at a minimum. Depends on what your other modifications are though.

    You can daily drive, but you'll run out of gas frequently due to the poor gas mileage. It also sucks to have to plan your drives around E85 stations. If you want to switch fuels, you have to be on top of things, and make sure you flash your ECU. Do you have a way to flash your ECU? You'll also have to pay for 2 tunes. A pump tune, and a E85 tune.

    As for the good side of things... Look at my build thread in my signature. I couldn't have ever considered making that much power / torque on a Dom1.5XT-R on 91 octane. The power / torque is phenominal!

    1) You can absolutely DD your car, provided you have ready access to E85 at the pump
    2) You absolutely need injectors and pump to handle the increased/different fuel
    3) I don't know of any good Subaru tuners in Miami that can handle E85; closest I can think of would be to drive to Atlanta GA and get tuned @ Top Speed Motorsports

    I wouldn't store E85 for prolonged periods. E85 is hydrophilic. It loves water. It'll absorb water out of the atmosphere, and degrade your fuel fairly quickly. It goes bad a lot quicker than gasoline does.

    You can do an E-Tune if you're really wanting to... but I wouldn't recommend it.

    I'd only purchase injector dynamic injectors, and I had the Walbro 255lph pump

    You never said what kind of car you're talking about.. I would suggest a Walbro 255 and ID725 injectors.

    The base Cobb maps will not be applicable. You'd need two custom tunes.

    Food for thought: Injector Dynamics - Alcohol Article

    ...Keep in mind, this is written by a company who makes and reconditions fuel injectors. They are knowledgeable and know their stuff.

    I used to want to run e85. Lately I've kinda been leaning more towards meth injection, personally. Both have their ups and downs.

    I can't speak to recent events, but the 65c had a lot of quality problems when it was first released. The Walbro 255lph is a much more proven unit.

    You have to tune for injectors, regardless of what fuel you are using.

    just spoke to cobb tunning (domestic pro tuners )

    he said walbro is not enough for new model wrx (running out of fuel)
    he will check and let me know about the fuel pump injectors and if i need some thing else to run e85
    he has not done new wrx for E85 (older one was ok with 255 pump)

    first he will do 93 with new pump and injectors
    after week or so later E85
    week later retune E85

    The walbro is plenty. Not to knock down cobb's knowledge.... But the "new model" WRX has 565cc injectors and a 2.5L engine with a turbo similar to the VF39. I had that setup (vf39 +2.5L on e85, and had no problems... Then I upgraded to a dominator 1.5XT-R turbo which is equivalent to a GT3071R turbo, ran 1000cc injectors, hit mid 400whp on a low reading dyno and never ran out of fuel. On a dyno jet I would've been in the high 4's or low 500's. All with a walbro 255lph.
