With E85 you would need to upgrade your filter and lines, and run bigger injectors.

E85 supposedly eats away at anything rubber, so you need to run PTFE lines. The disintegrating rubber lines will gum up your fuel filter and/or injectors.

Also, for 400+whp on E85 I would run at least -6 feed lines.

Are you saying upgraded lines as in larger diameter to meet 500 whp for E85, or upgraded lines as in a different material to handle E85? I ask because I'm running stock lines from the tank up to but not including the engine bay on my car, and only have updated the engine bay lines. But, my WHP goal is 400 or less.

Isn't the stock hard line (feed) equivalent to -6AN? I have heard that the banjo fitting at the hanger eventually becomes a restriction, but not sure at what power level / fuel flow requirement that is at.

You're fine. I ran E85 with stock lines up to the engine bay like you're saying with zero issues, stock fuel tank with ID1000's. Daily drove it for years this way making 600whp.

OP if you do run E85 you can easily make 500whp on ID1000's and stock lines.

Pretty sure 1000's will run out before 500whp on E85, unless you are bumping up your fuel pressure. Mine run out in the 400-450 range with a stock FPR.

Yes I am using E98, and I am using PTFE lines however back in the day I used the PTFE lines from my engine bay to a fuel filter to the rail and to a return. All my lines were stock from the engine bay back and ran a stock fuel tank. I mean obviously things have changed on my setup over the years, I know have a 1.9 gallon fuel tank in my engine bay but don't get concerned with E85 unless you are planning on not driving the car months at a time.

Yes I maxed my ID1000's out at 650whp before I added 4 more and then maxed 8 ID1000's out at about 950whp and now run 8 ID2000's. ID1000's and an adjustable FRP, you will be fine with 500whp.

‘I’m surprised you reached those power levels with 1000cc’s , im guessing you raised the baseline fuel pressure? I’m already close to 50% duty on my 2200’s

On our EG chassis, -6AN is larger than the stock hard lines. The AN hose fits pretty loosely over the hard line.

For sure on the return line, but I never tried one over the feed line and thought it was equivalent. I learned something today! :)

My buddy runs his turbo integra on stock lines with E85 no issues. I want to share this link in case anyones interested.
