What do I need to change in order to run E85 on my stock 420A?

i wonder if there would be a power increase on e85 on a stock engine...

There shouldn't be.
, your wrong. There will be a power increase as long as the engine is decently tuned. It will be on the order of 7%. If you were to run E98, it would be about 9%, and methanol is 13%.
Have a nice day.
I don't need E85 for more power. Pump gas is very expensive over here and E85 costs about 2/3 of it.
2/3 the price of gasoline, and almost 3/2 the amount needs to be injected, that's a perfect mathematical trade-off.

You're going to spend more on E85 than you will on gasoline. You need to inject more than 3/2 of it, and that 2/3 difference will be wiped out.
^^^ beat me to it, but heres my late and slightly alternative/wordy perspective.
IDK about 420a's but, on the turbo versions... I recently weighed the pros/cons and although e85 is about 2/3 the price of gas for me, (actually better than that because I believe you run regular? no? and I have to run premium, but its still 2:3 for me)
the only problem is you have to flow about 33%.
And for what? the same miles per dollar? each gallon will be cheaper but you will use more. in my case, I dont win in mpg vs price discount, so i didnt switch. for n/a it may be different, but I am doubtful.

While that's a good point, we have already established that his car is a 420a (in previous threads that you would need to read, . He also posted in his sig that he is 420a).Has anyone notice that hes car is not the 420a engine hes on europe, they dont use 420a engine over there they use the 4g63 n/a.

Curious theory conversation so far, but I do want to point something out; our ecu's are not tunable so we have to presume that he is not going to be able to adjust his. Thus he can't take advantage of the qualities of the E85. His ECU will take in info from the O2 (and other sensors) to adjust the fuel useage based on "formula's" built into the ECU. So as its looking for that stoich (or whatever point it wants to hit at what rpm/throttle/density) how do the qualities of the E85 come into play there?
