      Alright guys, I've been lurking around here for a number of years and the forced induction forum has been of great assistance with my build. Since I got my car back on the road about a year ago I've has some nagging fuel issues that I've finally traced down. E85 is plentiful here in Indiana and I'd like to take advantage of the benefits it has. Long story short I'm looking for info and advice on getting my car ready for corn juice. Current fueling set up is as follows, but is definitely subject to change:

      Lugtronic ECU
      630cc injectors
      Stock fuel rail/lines
      4 bar fpr
      Walbro 255 in-tank, soon to be replaced with a stock pump and something in line
      New wiring harness coming from Kevin with fuel pressure sensor

      Thanks in advance for any input!

      Around 20 psi and your injectors will be around maximum. Milbroz in Sweden did easy 796whp on E85 with stock fuellines,stock fuelrail and 4bar fpr.

      Wowza, that's nuts. Guess I just need a new pump and I'll be ok.

      044 and walbro225 aint designed for alcohol, those will stop working sooner (2 weeks) or later.
      Get Dw200 or Dw300 or new Walbro E85 or any other pump what can handle alcohols.

      I guess my next question is how are you guys plumbing these pumps? Just running new line with A/N fittings or stock? I hear e85 is more corrosive than gasoline.

      Bumping this up.

      Looks like I'm going with the INA surge tank/044 combo, new lines and a new rail. Seeing the new ID injectors from USRT has me thinking about replacing the Siemens 630cc that I've heard some horror stories about.

      Many of us are running 044 pumps. Have also used ID1000, ID2000, Siemens 630cc and 840cc

      no reason to change your lines. your car was made after the mandate that all cars fuel systems handle alternative fuels. save yourself some money, and headache from leaky lines.

      i wouldn't only be changing the lines to go bigger and have a nice tidy setup from the surge tank to the rail, and back.

      Kevin, I'm emailing you now anyway.
