So you just aren't satisfied with the complete list that 'wantboost' gave you?
Or are you asking for exact manufacturers part numbers for the parts you need?
If that's the case, you should change the title of your post to "please Google this for me because I'm THAT lazy".

So to help u out bro as I see no one else here will guide u. Trust me I learned the hard way too, people nowadays
Yes fuel pump u should search on lime for something above 25th
(Aem, skunk2, walbro, and high flow) make great in tank pumps for us Hondas
Injectors if u using or Need 1000cc right now up it by 500cc at least.
Re tune oh yes this is a biggie!!
Also don't forget if u can a air fuel gauge
Good luck end can be a bit unstable so some days u have mad power and other fill ups u won't

yea I don't know if that was even english.
Here's the big issue with gas station e85. It isn't consistently 85% ethanol... the purity and quality varies... i've seen it as low as 50% ethanol to 80% from the same station at different times, it's almost always never 85% ethanol.
To get the car to run the best you need to do a flex fuel tune (if your engine management system supports it) first you need an ethanol content analyzer, gm units can be purchased off ebay or zeitronix has a nice affordable sensor. it is installed on the fuel return line and tells the ecu the ethanol percentage of the fuel.
so install and wire up the ethanol sensor (wideband required for tuning) and do a tune on straight 93 octane. Drain the fuel system and then do a tune with ethanol that's actually 85% ethanol (buying a 5 gallon pail from a race fuel supplier is the easiest way to guarantee purity) with flex fuel enabled the ecu will read the ethanol content from the sensor and automatically blend the 93 and e85 fuel and ignition maps to allow the motor to run the best.
the nice part about this is if you are somewhere that doesn't have e85 you can still fill the car up with 93 and drive home with no issues, no tune swapping, etc.

All I did was use bigger injectors (550cc on 8psi), and a walbro 290 fuel pump - both of which I already had installed anyway.
Then I just started tuning with my wideband.
I suppose I could replace those two tiny sections of hose by my gas tank with newer e85 compatible units, but idk if that's absolutely necessary.

Why are you bumping a thread that's on the first page? do it again and I'm locking this thread.
we've already told you repeatedly what you have to do to run e85. If you can't comprehend our simple instructions then you shouldn't do it or let the professionals do it.

Do we all need one opinion from people we don't know and have no idea if they even have the experience with the question at hand?
I have no reason to doubt you but I don't believe half the jumbo you type

let's make this even dumber and easier...
fuel pump - must be ethanol compatible, size depends on power level, brand is personal preference
fuel injectors - must be e85 compatible, size depends on displacement and power goal, brand is personal preference
fuel lines - must be ethanol resistant
fuel pressure regulator - current regulator is fine
fuel filter - must be e85 compatible, brand is personal preference, a filter with a reusable stainless steel filter element is preferred
now was that hard?

When it comes to brands we can't tell you what is best for you,we can suggest brands but in the end it's your decision.
it comes down to your budget and your personal preference

I guess I haven't really research too then, as I didn't know anything about the ethanol content analyzer on the fuel return line. I alway though you can just run e85 with a ethanol capatible fuel pump with stock line capatible filter and capatible bigger injector if you stay under a reasonable amount of hp, I remember seeing some testing showing that e85 does not harm the oem fuel tank and line and the only reason for upgrading fuel line is if your trying to go way beyond 500+whp.
I think out here in az some of the pumps state that e85 is a min 70ish% ethanol.
The stock lines will handle more than 500hp on e85, not sure what the upper limit is but I recal hearing some people peaking 600+ on the stock lines

I HAVE PERSONALLY RAN E85 FOR A YEAR ON A WHALBRO 255 AND STOCK LINES THROUGH RC INJECTORS WITH NO PROBLEMS AND THE GAS SAT FOR 6-8 MONTHS AFTER AND I HAD NO PROBLEMS ON START UP. STILL RUNNING THE SAME SETUP TODAY SAME PUMP SAME LINES SAME INJECTORS
Was that hard to understand?

Doing a general test for "e85" is pretty simple. I would test the stations around you in 2 week intervals. It would tell you whats high and whats low. The swing of 5% ethanol will not hurt anything.
Quick Keys to going on E85:
-Double your injector size of what you would on Petrol
-Stock lines and filters work, as long as they are clean and not damaged
-Walbro will get you to about the 420-450whp (dynojet) area based on the fuel system
-There is a lot of rumors online about E85
-Most of the time, e85 is not 85%. It is not the end of the world, test and make sure you are getting the same blend.
