I have a 2000 Civic SI with B20 V-tech turbo i was wondering what is required to run E85 in my car i will give you a quick break down of what i have. Im running a Dual in tank Walbro system to the Fuel rail with -8 line and a -6 return im currently making about 600 Hp to the wheels. I was told that you have to swtch all the lines to metal first before running E 85 can you help me out

All you really need to do is get a set of larger injectors (since E85 requires 30% more fuel) and a retune. Pretty much as simple as that...

if you dont mind buying a new fuel filter, dont use a cellulose filter, get a ss mesh filter. we had a problem on our s2000 sandrail once we switched to e85, it kept missing while accelerating. all we changed was the filter and it runs perfect.

does oem honda filter work with e85 ?

it does, but not worth it..... upgrade to a new one.

since youre buying a new injector set, you can get the alcohol friendly ones and maybe annodized fuel fittings?

v-tech....lol

Not needed, I run shelf RC 1000's that have had 15k miles of E85 run through them, I had them cleaned and flowed in the spring and they were just fine. My friend put the bulk of those miles on my injectors and he was on a 100% OEM fuel system besides the rail, pump and injectors. He had OEM Lines, Filter, Banjo Fittings etc and there was no oxidation on/in anything, he even left 6 gallons of E85 in his tank from November of last year to October of this year and his tank was not oxidized inside.

^^ Exactly. I dont want to push people to be less cautious, but i think some of the worries of E85 use have been exaggerated slightly. I know a few people who run it and have never had problems with the stock fuel system.

My understanding is that the E85 will eat the rubber in the lines over time.

redboost10

its possible

Use what you got and dont worry about it, I am speaking from personal experience, what I posted above should be more than enough to satisfy you, the same friend I mentioned just retuned on a 42R setup with twin walbro's and 1600's and made 560whp at 18psi, still using the OEM 2+yr old fuel filter and rubber lines with the banjo fittings. I would be more worried with the task of trying to control 600whp to the wheels on the street, its a real handful!!!! If you make that now on race gas and your fuel setup is up to par you can easily make that on the street with e85 at a much cheaper price.

I have been running e85 since july.....NP at all.....3500miles and counting DD@ 421whp

the deterioration of rubber fuel lines is more of a long term effect. running e85 on a dd will have little to no effects on rubber fuel lines. im talking about letting the car sit weekend to weekend and over the winter if its a strip only car, thats when the rubber will deteriorate when using alcohol as fuel.

at that power level you are going to need a very large injector with E85

1200's and crossed fingers or 1600's and plenty to spare but shitty to tolerable driving characteristics.

Im running 1000cc imjectors on the car right now that should be sufficient enough i would think to hit my HP mark of 600HP or more.im running a precision Turbo custom echaust manifold and victor X manifold getting ready to install skunk pro 1 cams and springs and retainers as well. this should do the trick. my previous was 550.00 hp on 50/50 mix of 92 octance and C16 race fuel, no skunk cams was running Gsr and was at about 20 pounds of boost or so.sounds like ill be running E85 in my car.

96 GSR-T

if you are shooting for 600whp you WILL not have enough fuel, the 1000's will not do it.

Boostinb20!

What can i squeeze out of them then, or is it better to run on just race fuel i know my car will make about 600 with race fuel i would think i could be almost there with the same set up.

96 GSR-T

E85 as already stated requires generally 30% more fuel than gasoline, so with 1000's and your twin pumps I wouldnt expect over 550whp. Obviously numbers vary from dyno to dyno.........

Boostinb20!

Is there a real HP gain from Fuel to E85 sems to me ill be going through gas real quick keep in mind this a a full interior daily driven civic.

96 GSR-T

you will gain a small % of horsepower with just the fuel swap, all the extra power is made by running extra boost and in turn making more power that isnt possible on 93 octane, I was averaging 23-26mpg beating on the car pretty good this summer. I can pretty much say confidently that I wouldnt of made more than 500whp on pump gas, I made almost 600 at 23psi and would of made more if I had bigger Injectors.

obviously 105 octane > 93 octane in a boosted motor

Ive been running E85 in my car for the past 8months...with over 15K miles...my tuner and them have been running E85 for the past 2 years with no problems on Stock fuel lines... i think it comes down to the cars in the old days were the ones that had problems with Ethanol and rubber fuel lines... check this video out about E85 :

Dude im making 465whp @17psi and my precision 1000cc's are well over 100% Duty cycle 600whp you will need a 1600cc injector to be safe!

If your using an aftermarket fuel rail, make sure the coating on it ( paint ) is of good quality or else it will get eaten away.
