Rebel2k4 is running an Mx3 turbo KL power car running E85. Making 400Whp
I've considered it.
Its closer to 105 RON, for a boosted engine the potential is great in terms of performance.
I wouldnt consider doing it for economic reasons.
you would need to raise the compression to at least 12:1 on an NA engine to get a useful performance gain, and even then expect it to use 33% more fuel.
So it needs to be at least 33% cheaper to break even, then there is the less distance out of a tank issue.
If you still want to do it....I believe you probably wont need change all that much except you'll need 40% bigger injectors, and maybe a bigger fuel pump and lines depending on the power increase your looking at. then it wont run on anything else after you've made the modifications, as the variations in AFR will be outside the ECUs self tuning range.
Steel lines and tank are OK generally, so is neoprene lines, some aluminium alloys and zinc alloys are no good, I was going to make up a SS fuel rail. Other people have not done this however and the rail seems to be OK.
You will at least need to change the fuel filter on the transition and then change it alot more often.
Do a google search on E85 and E85 conversions, and you'll find alot of interesting articles on the subject.
