Anyone know the exact things I need to run E85? I know I need upgraded injectors, but how would i Convert to Top feed and what kind of pump would I need?

What pump do you recommend.

Unless your car is a 2004-2006 STi, or 2005-2006 LGT you already have top feed injectors.
The cheapest pump is probably the Walbro 255lph. There are also Deatschwerks pumps (300) that specifically state they are e85 compatible and don't cost too much more. All you really need is 30-40% higher flowing injectors, a fuel pump capable of keeping up with the increased demand, and a tune.
I ran a DW. 65c fuel pump on e85 in my 2011 wrx
How long did you run straight e85? I just read that e85 will really mess your car up.

About 10k miles. No problems at all.

If your car is from the 70s, yeah, it will mess it up. Every car manufactured after 1986 or so is designed to be ethanol compatible. You just can't run it without being tuned specifically for it.
I went over to NASIOC and right now im running about 20% ethanol and the rest 93 octane, I cant wait to run full e85

Who's doing your tuning?
Noone as of yet, they said I should be safe running a low percentage of e85 mixed with fuel and not require a tune, however once I go full e85 im probably going to Precision Tuning in Jersey.

What's your AFR with e20? I would think that much is starting to push it dangerously lean.
Not sure, but the car is running pretty good, atleast thats what my butt dyno says. lol

Yea.. but the butt dyno doesn't tell you you're burning valves or stressing the #4 ringland until it fails and the motor is trash.
I would at least data log it to be sure you're not damaging anything. e20 is about as far as I would feel comfortable without a specific tune, but only if my data logs checked out good.
