Have a 95 z28. Car is currently tuned to run on 93 pump gas. I wanted to eventually run more boost and have it tuned to run on E85. The car has 60# injectors I beleive with two walbro fuel pumps and all custom stanless steel braided lines custom ran into the intake. What's everything I have to change, upgrade to run E85 - I'm new to all this stuff.

As far as I know, all hard lines are good to go in terms of E85. All seals that have been manufactured since about 1985 are also good for E85, since ethanol has been a chief component of modern gasolines as an anti-knock additive since the mid-80's.

You've increased your fuel delivery....added the requisite 30% additional volume capacity to your injectors... About the only two things I can think of is to double-check with the manufacturer of the braided stainless lines to ensure that the inner material is ethanol resistant, and the second is to get an E85 tune into the computer. Which system do you have?

Fast systems are capable of handling four separate, switched fuel maps, and can also be set up with fuel type multipliers in the lamda calculation for closed loop WOT operation with wide band O2 sensors. That's what I've got and I'm thinking hard about E85 as well.
