    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
    Cobb does e-tuning now? Because they don't have a shop in Miami...

    Domestic pro-tuners is the section that all of the tuners are listed in.

    Ramini motorsports is the name of the tuner in Tamarac. I have no experience with them.

    I told you my first hand experience with my walbro. If you're uncomfortable with that, then purchase a larger pump. I can promise you that a properly functioning walbro 255 will be more than enough pump for your application.

    I second that the Walbro 255lph will be sufficient. Of course you could go with a Aeromotive 340lph, or the relatively new Walbro 450lph e85 pump.. both would work just fine and outflow the 255 by quite a bit. I would not even consider a double pumper unless you're running a large turbo and shooting for over 500whp..

    i am not going with double pump. i think walbro 450 is right and 1000cc injectors

    but my main problem is the tuner.
    not a single tuner (good one) in 200 miles around miami

    Robin, just out of curiosity... if you run dual pumps, do you run a single pump/damper/filter for each fuel rail separately?

    You run the two lines from the pumps to a Y block into a single feed line. Then after the filter in the engine bay another Y block to parallel lines going to the rails.



    Running the rails off of individual pumps would be really inconsistent fueling, and you would have to run both pumps all the time. The way mine is set up the second pump only kicks on when the boost pressure crosses a predefined threshold.

    Huh. I wonder if anyone is running dual pumps on a returnless system, one to each fuel rail.
