im planning on making my 91 EF with a b16 swap run on e85. i know i will need bigger injectors, possibly a fuel pump, some ecu tunneage, and possibly ss fuel lines, among other things. i need to know what pump i should get, what size injectors, and what chip works the best, im guessing its hondata. also anything else im missing would be great. i want to be able to fully run on e85 24/7.

 

Why?

 

mostly because i want to run high comp. pistons and dont want to pay for the extra octane. also because it would be cool, and unique.

 

up.

 

im pretty sure you have to do fuel lines

 

well, at least you have a reason. Although i don't know about it being cool. Ethanol is about the dumbest idea i have heard of.

I think your right about changing the lines. it seems like i read that it will eat away typical rubber lines.

 

E85 is not going to eat your fuel lines.. There is 10% ethanol already in most gas you buy. A higher concentration will make no difference.

 

if you have a steel gas tank you should probably do something about it, i hear that e85 will eat through steel and other metals, but i believe its OK with anything anodized and I'm about 90% sure stainless steel is good to go.
correct me if I'm wrong

 

i just looked it up, steel is fine, aluminum isnt. what im really worried about is the gasket material and any other seals. anyone have any ideas about ethanol safe gaskets?

 

Ethanol can break down resins and fillers in fiberglass gas tanks, causing them to leak.
Resins leached from fiberglass tanks can go through the fuel system, sticking to valves and other internal engine parts. These deposits have caused bent pushrods and have clogged intake valves.
The alcohol attracts water, leading to increased corrosion in metal gas tanks.
Water in the fuel affects the octane and leads to knocking and decreased performance.
Ethanol acts as an efficient solvent, gradually cleaning out the accumulated gunk in fuel tanks and lines, and clogging carburetors.
Certain rubber gaskets and fuel lines are weakened by ethanol.

apparently the e85 itself dose not do anything to metal tanks but the added air dose.

"Most fuel hoses made after 1984 and marked with SAE J1527 are designed to withstand ethanol."

other than that im not really sure what else it will do.
just tryin to help and actually thinking about running it myself

 

Man, E85 bent the pushrods right out of my block!! i can't even find them..

 

I was also thinking about doing an E85 project. Simply for the cheap high octane fuel. But like we know E85 likes to destroy rubber and gaskets. So basically every gasket in the fuel system needs to be replaced. Its probably easier to do a full aftermarket setup. Most companies list their fuel products as race fuel compatible. Seems way to expensive for me.

 

i dont think its worth the time and money when gas is 1.70 a gallon

IDEA:

You could save all the money that you want to spend to convert your entire fuel system to run crap gas, and just buy premium.

 

fuel pump should be fine, as would the lines. Step up to probably DSM 390cc/min injectors, they are cheap and will work. Then remap the ecu. Might be able to get away with an SAFC to dial the tune in, last conversion I did it ran with just stepping up the injectors, and only needed leaned out a small amount. I went from 210cc/min to 450cc/min. The 390's might put it close enough that an SAFC will be ok.
