Im wanting to convert to E 85 fiuel . What all would i need to do this? I have seen some articles where a stock gt can pick up to 19 rwhp just by switching. The E 85 fuel is more oxygenated than reguler fuel, thats where the extra hp comes from, also on higer compresion, turbo, supercharged engines can run more timing due to the higher octane rating ( 116) i think.

Its been my experience that your MPG's drop significantly on e85 fuel as well. Not sure if that matters to you or not.

imho it is not worth it unless you are running alot of boost on a built motor. i will be running it on my car but i will also be pushing 20-25 psi out of a twin turbo kit

You would have to get a performance fuel pump and bigger injectors also the tune.

I heard also it can eat at the gaskets in motor if its not built for it.

^this. I dont think its worth it at all until you go with high boost.

You need new pumps, injectors, and possibly even new rails and fuel lines. And when you run a dual pump setup you need to buy dual FPDM's so itll just turn into a big project

E85 uses about 30% more fuel. Find injectors and a fuel pump that'll support your power level and the extra 30% fuel. Get it tuned and enjoy.
