Also search the alternative fuel section for posts from people way smarter then me. I think GST motorsports has been running E85 for over 2 years and all the seals and everything is fine. Mike from AWDmotorsports pulled his motor and disassembled it. It had been ran on E for a while as well. Parts were in damn good condition.
Like most ppl know, cars that run on E85 aren't very reliable on winter due to being hard to start. And up in the north it's so bad that even diesels don't start on a cold day. The locals only use 2-stroke snowmobiles due to the small problem that the fourstrokes don't start when it's below -22F. So I wouldn't have E85 if you have that cold winters even if a block heater helps
.If the E85/E75 is world wide, then I know that tuners don't recommend using the E85 tune when running it on E75.

I would for sure make the switch.. Only concerns I would have is availbilty in the area and cold weather starting other than that the gains are amazing. I would suggest getting oil catch can.
You don't have to have one to run e85. There is a breather hose that runs from the valve cover into the intake. When you run elevated boost you can have oil and oil rich vapors flow through there and back into the intake. That is not good for your turbo or any parts in the charging system (ie where the air is pressurized. In intercooler, etc.). When you run e85 you are almost always cranking the boost up which will really cause a good bit of oil to flow through that breather. Most people hook that valve breather to an oil catch to prevent the recirculation of oil through the intake.

and catch can is not a must but its good to have, you will rarely see any oil down the intake manifold or IC pipes even u drive it hard or boosted high but i dont know if u talking past 35psi
