I have a 00 GT.
Can I convert this to run on E85 like the FFV's from Ford?

How about my 04 Expedition with the 5.4 V8?

Nobody has any input on this?
Is this an easy thing to do (fuel lines, injectors) or is it way too involved to even consider?
I heard someone say it was possible...

In short, it would be difficult.
One of the biggest problems comes from the fact that the stoicometric ratio for ethanol is 10:1. With your 15% gas added, it should bump to 10.7:1, but that is still far different from your 14.7:1 on all gas now. Basically, it will require nearly 40% more fuel volume flow than what the currerent demands are.
You will need bigger injectors, and most likely different seals and rubbers in the tank/lines to cope with the ethanol. You will also need to either go with an aftermarket ECU or figure out how to get the stocker to injector more fuel, and then use the correct stoic ratio for cruise.

Personally, I would love to get a car running on E85. My only problems is the stations are too far in between. I have one 30miles to the west, and one 35 miles to the east, but 70+ miles is a 1/3rd of a tank of gas.
I would enjoy converting my 88 2.3 turbo to run on the E85. With an octane of 105, and being oxygenated, I could really make some power. hehehe

Thanks, I hope Ford makes a kit someday.
I don't have any Ethanol stations where I live (there's a Hydrogen station down the street, believe it or not) but I really would like to send money to farmer bob rather than shiekh abdullah...
I guess Arnold has madated many more E85 stations be buit in CA soon.

Stoich for E85 is 9.7 The stock injectors and would be able to keep up with that because you are not changing the load, and the EEC could be tuned to run at that afr. The main problem would be that the o2's could not read at that level, so I'm not sure how you could work around that.

E85 is averaging about $.40 to $.50 less a gallon from the $2.80 - $2.90 for regular unleaded. So basically, it's almost 20% lower in price. Flex fuel vehicles normally average 30% less mileage when using E85 compared to the normal fuel burning engines. So basically, the "break even" point to monetarily is a price 30% lower - and that's just to come out even.

Here in southern California, the cheapest regular is $3.19. And my car pings a little on regular, so I use plus, which is $3.29.
Besides, like I said, I'm all about paying for a new John Deere for Bob than a new Ferrari for Abduhl.

Even if you come out even with Ethanol, i think the major point is we are use way less gas. Instead of making crazy leaders in foreign countries wealthy we are sending the cash to Farmer bob and his familiy in Ohio.

Plus it feels better to pay less each visit, even if they are more frequent.
