E85 ka24de

[bradspiker240]

What’s up guys. novice here, but my current set up in my s14 is a Ka24de, fresh rebuild with all oem parts, and bc 264/264 cams. I’m highly interested in running e85. I’ve done some research, but yet here I am asking anyway. What all would be needed to run e85? Tune, new fuel lines, bigger fuel pump and bigger injectors? I know e85 uses more fuel than regular pump. Injectors need to be bigger to compensate for more fuel needed. Any certain parts that you recommend? I don’t want trash or cheap quality

Update** 750cc five o injectors, walbro 255, z32 fuel filter and tune by rs enthalpy. Can use stock lines for my set up. Annnnnnnd action

Optimally an in-line ethanol content sensor that is communicating with the ecu and allowing it to adjust for different ethanol percentages.

[bradspiker240]

Awesome. I’ll look into that.

You'd need a standalone ems of some sort. With the enthalpy tune you'll be stuck with either an e85 only tune, or dual tunes that are switchable say one for pump gas and one for e85, but you'd need to make sure the tank was nearly empty when filling up and changing fuels.

I got ya. Yeah for now I just want e85. There is a station that sells it 5 min down the road. And another place that sells it on my way to work. I’ll be sure to empty all contents of fuel before filling. I’ll prime the hell out of it with my power probe to make sure only ethanol is in there.

Nistune supports Flex Fuel, so does Nismotronic

[souljaseth33]

+1 for Nismotronic

[TheRealSy90]

Ah I forget that some newer daughterboard options offer flex fuel now. Definitely appealing compared to the cost of a popular standalone.

Watch the local content of the E85 you can get, it can be something besides 85% I hear. Which is why the flex-fuel sensor is so important for performance builds.

It wouldn't matter for a stock engine nearly as much.
