Fellow Adaptronic user, also lusting for E85, watching intently

Send me those injectors and I will be happy to 'break them in' for you

Sorry for the noob question - I haven't been keeping up lately, but basically the only hardware changes needed to run E85 in my miata is a bigger fuel pump, larger injectors, and a new fuel filter? What about ignition?

I just started reading about this so I don't know much, but it looks like ethanol combustion is C2H5OH + 3O2 → 2CO2 + 3H2O + heat. What toxic byproducts are released and can I remove my cat converter? If someone has any good reading on e85 please lmk because this is very intriguing to me.

If that is all that's needed, then I'll be right behind ya after I get my welder. What kind of turbo did you get?

NB's run different (stronger? more pressure? not sure) fuel pressure regulators, so you'll probably need an adjustable fpr. Maybe bigger lines/rail. I'm trying it out with the stock rail/lines cause according to some peoples (on here) calculations they should provide enough flow and be sufficient for my goals of low to mid 300's whp.

By products? Don't know don't care: I'm completely catless.

Turbo is a 3076r

The 1999-2000 (like yours and mine) have returnless fuel systems that run at about 63 psi.

E85 is still 15% gasoline, but overall the combustion is cleaner.

You two dudes who are going to try out the stock rail. Do a little experiment and run a pressure gauge on the fuel lines. See if you have consistent delivery at the big end on the dyno. At least then you won't be unsure if you have enough fuel delivery.

My fueling setup was cheap insurance, compared to the engine build, but still expensive at probably like $800 among the rail, pump, afpr and all the hoses.

BTW, I'll photograph my plugs this weekend. Clean burn doesn't start to describe it. The first set just had a slight yellow tinge on the ceramic after a number of hard pulls on the dyno.

Man, I wish e85 was more readily (simply available) up here in Canada. This should change since we have a butt-load of flex fuel vehicles. I too have an NB miata so I will definitley be following your porgress 18psi (keep us updated on your findings).

LOL, someone got a good deal, methinks!

azn, don't be skeered. I got mine at least running well enough to load onto the trailer and get it to the dyno just by changing my fuel constant in the MS. And I went from 1.6 with 450's on gas to a 1.9 with 1000's on E85. Surprised how easy it started.

Seeing what I saw on the pump sock after just a little running, anyone running E85 should probably go ahead and change all the filter stuff out after running a few tanks through. I think the alcohol is a better solvent than gasoline, a lot of gunk gets loosened up.

My plan was to go a little further and get rid of the stock fuel filter and put a canister type filter in place under the hood. It's a very easy fit-up when you are running all braided AN lines. I think I found a few pretty cheap ones from Summit and/or Pegasus, just make sure they are for fuel injected systems to handle the pressure and will work with alky.

lol..I sure did. Time to sell my two sets of RC injectors.

I wonder if there is a way to do flex fuel and which EMS can do that.

You can use a GM device that detects the level of gas vs ethanol in the fuel system, IIRC they cost about $100. There are folks in the DSM world that have talked about wiring one in with MS but I don't think I've read about anyone actually following through.

Adaptronic can do that. You just need the flex fuel sensor.

On par with respect to size or materials?

I think webby459 already did that on his NA. He said it works well.
Do it Andrew!! I want to know the dyno hp from your motor.
