well i was wondering if there are any alternative fule conversion kits for the rsx or k20? i have heard of alternative fuels like E85 and Biodeisel but has anyone ever used them in a honda?

 

I believe there is a thread I've seen about a biodeisel conversion.

 

ok well find it and show me

 

You should search yourself ... and E85 would work in the car with little mods to it. Alot of Evo and STI guys are running it because it has a higher octan rating and they have forged pistons, That is the biggest thing that you need ... the pistons.. It will also take something like 25-33% more fuel so a better fuel pump and fuel system. My local tuner shop has a civic ls/vtec that is turbo'd and they are running E85. Something like 600hp that they are dyno. I could ask them to see what they all did. Biodiesel more likely wouldn't work well because it is less processed. But if you do find a kit post it up. Hope my non sense made some sense.

 

Why would you want to do this anyway?

You've got 185 posts and been member since 06, you know how this works.

Again, why would you want to do this or are you just curious about it.

 

well e85 has an octane rating of about 105-110 and is about 2 dollars a gallon and i live in socal where 91 octane is about 3.40 per gallon right now so i figure if i can get higher octane at a cheaper price and fuel that burns cleaner and is over all better for my car why not

why would i need forged pistons the kits i have seen on the internet just show bigger injectors and a modded fuel system i just havent seen a kit for the rsx

 

because you are running a higher octan it is harder on parts to a point. , and is guess i was more talking about b series, I havent worked alot with the k20 yet so a.

 

Gas prices suck here too. More power to you on the setup. Post up if you get it installed.

 

new fuel injectors and MAYBE a bigger fuel pump are all that are necessary really for E85. there are alot of things you can do to the fuel system for safety and longevity but you can do the research on that. i say on $2.66 race gas. and if tuned right its just as easy to pass emissions, so you wont have any owrries there.

You'll melt the stock pistons.

 

i would really like to see some kind of documentation on that. i really do not believe that is true and for you to tell everyone here that E85 requires forged pistons calls for some proof. ive been researching E85 for a year now and have never once come across that info before.

 

I seen it on the news like 2 years ago. They showed pictures.

 

haha......

 

you'll need to upgrade your fuel tank to stainless steel and upgrade all rubber lines to hard lines ... E85 will eat away rubber components!

 

The Rubber thing is true and it wont fully melt your pistons but it will eat away with the pistons and then as time goes on the pistons will get little holes on the top and it will eat through the piston rings.Your compirsion is go down. Then the rings go and you wont be going any where for a while. Again It wont do it in week or even a month it will take time to do that. And it is going to mess with your Air/ fuel mix. I cant and dont have full documation on this it is just what i have heard and have see here and there from different locations. If your really want I will do a full right on it.

 

how can E85 melt pistons when it has a lower combustion temp than gasoline?

 

well the only thing i heard about e85 is that it has a high amount of water in it so without the right additives it can rust the inside of your motor

 

All of the Info i have been hearing about it is Hear-say so I cant tell you anything for sure and i dont mean to come off like I know for fact. But my friend and I are testing it in a 1993 dx so we will see what happens. I have search on the web and there isnt much out there so i guess its time to start testing. On a side note i just bought an evo and i have been on the evotuners and or evo forums. They are useing it on the high boost apps. because of the higher octan rateing and they are running safe with out any mobs besides the fuel system.

 

i just did a research paper on this for one of my college classes

the only things that would be needed are a larger fuel pump, stainless steel lines in place of rubber lines, and injectors that are roughly twice the size as stock, and get your car tuned to stoich which i believe is around 8:1 with E-85

your stock motor will be perfectly fine and will make more power with very slightly less gas mileage..... yes the car will need more fuel but it will also make more power which will help even out the gas mileage

I agree with everything - except the gas mileage. Your miles per gallon of fuel will go down, by a lot. You need almost 2x as much e85 to travel a given distance versus gasoline. So where you were getting 30mpg, you'll get like 18 with e85. The cruising range of your car goes down as well unless you also increase the size of your fuel tank.

The real measure is cost per mile driven. If e85 is $2.00/gallon and you need 2x as much of it to travel a given distance, then gasoline priced at $4 would be equal in terms of economy (perhaps not emissions).

Anyhow, IMO, e85 makes the most sense in high compression motors as they tend to be able to extract more power from the e85.

Again, I'll reiterate what's been said before, the only changes needed are properly sized injectors (possibly a re-tuned fuel/ignition map), upgraded fuel pump, and replacing all rubber components in the fuel system with metal lines. You'll also have to periodically replace any o-rings. Forged pistons are NOT required.

 

Waste of money honestly

 

its a waste of money to help the corn farmers of america while getting more power, cheaper gas, and better emissions??

 

From testing I have found that it is not that bad of gas mileage difference and its not twice the size injectors more like 30%. I did this on a stock d16z6 of 13 tanks of gas. Only thing done to the car is a AEM v2 cold air and plugs, wires. I would get about 38mpg high with 93, 37 ish on 89 and 36-37 ish on 87. E85 gave me about 28 highway. Now for the avg i got 25 with e85 and 30 is 87, 32 with 93. I run the E85 in 13 tanks of gas. the 87 and 93 i got before i started this and this is all about numbers. I check my lines and everything and didn't see any problems. the car has 120,000 on it and it felt about the same as on 93. High rpms feel a luggish but i beleive that is becuase im maxing my injectors. I stopped running 100%E85 and not run about a 50/50 with 87 and e85. I feels good and gas mileage is in the 30. I do 85-90% highway driveing to work.
