E85?
How difficult or what do I need to do to run e85 in my for the most part stock t2?
|
standalone ECU, larger injectors, bigger fuel pump, and REALLY REALLY REALLY clean the shit out of the gas tank. also e85 rubber fuel lines.
|
Ok sweet, I have 750cc primary and 1200cc secondary's not in it now but have them, also i have a walbro 225 not in yet either, as far as the standalone whats a good brand or where can I find them? When and if i switch over is e85 bad for a rotary? I was thinking it isnt but i dont know lol. Also if I do this would I need to take to a tuner and have them dyno tune the car after making it standalone?
|
Its a Good amount of trouble for a stock car
|
It would be pretty pointless.
E85 has less power stored in it, but higher octane, so in order for it to be useful you need very high compressor and/or very high boost. neither of which you have. it's also dryer than gasoline, so you'd probably have to premix and put more 2-stroke in than usual, not to mention, I don't know how e85 will mix with 2 stroke... |

https://www.rx7club.com/single-turbo.../#post11088073 Be forewarned that typically E85 will corrode most fuel system / components that were not originally designed to handle that fuel. You may very well need to change more than just the rubber fuel line. |
The reason I want to do this is because here in colorado if you run E85 you become emissions exempt for ever lol. So that way i would have to worry about putting the car back to stock just to pass emisions. I do have plans for the car, I want to run a gt35r or something of that nature, I already have full racing beat exhaust the rev2 one, and have the injectors and fuel pump, Just lacking turbo ecu and probably a few other things. But I just know all my dsm and toyota friends with e85 never have to do emissions again and now they can run rediculous set ups just for that reason

Do you have some documentation concerning that? I and some of my friends in CO would be very interested in this...

I dont personally no, but ill ask them what they had to do to do it. My friend has a 1G eclipse gsx and has a emissions exempt sticker now since he did that, so I will ask him hoe and post on here what he did to do it lol:icon_tup:
"** Hybrid electric vehicles, such as the Toyota Prius and Honda Insight, and other alternatively powered vehicles do not currently require emissions inspections. For further information on exemptions, call your county motor vehicle office, or the Colorado Division of Motor Vehicles' Emissions Program Office at 303-205-5603. Also see information regarding vehicles manufactured outside the U.S. and kit cars" Air Care Colorado :: Exemptions |
but if you are stock why are you worried about it?

beanol is another additive for premix.

I'm concerned that this is just some policy set by the DMV and not codified into law (subject to change at any time), that the OP's friend is lying or misrepresenting what he did (the word of someone's friend I don't know isn't strong evidence in my view), and that the EPA does not accept conversion since it touches emission control devices (fuel system and ECU) which has hefty fines for violators. Many states have duplicate laws, and while your risk of being caught is low when you don't have emissions, being inspected every other year is a risk. |

I now have the racing beat rev2 exhaust and it has no cats. Also my plan is to upgrade in the near future probably will happen with my tax refund. So with running the e85 would hopefully allow me not to test for a while.

It sounds like he wants to upgrade, and doesn't want to worry about Colorado emissions. Colorado emissions is very similar to CA, a visual inspection of the engine bay, air pump, and cat, and then a tail pipe sniff test on a dyno. The problem with Colorado is that the age necessary for classic or collector plates was set to model year '75. If you have a model year '75 year or older car, you can get collector plates and never worry about emissions again. All newer cars must get an emissions test every two years. Currently nearly every RX-7 in Colorado must get emissions every two years forever, unless the law changes (which I doubt it ever will).

The "friend" is actually a friend of a friend. So I usually meet up with them once a week for some beers, ill ask him again on sunday if what he said is legit, you bring up alot of thoughts for me i appreciate that. Basically I am just trying to figure out a way I can upgrade and never have to go back to the stock stuff just to pass emissions. I know its only one day is needed to pass, but to swap all the stuff it can be a pain in the ass. And thank you guys for all your imput! :icon_tup::nod: |
I can tell you switching to E85 was not cheap.. There is the the cheap way and the right way. I went the right way.. I made 443rwhp and 342 ft at 18psi . I'll post pics of what it take to setup your car the right way..

The most important thing to consider about E85 is that the ratio varies quite a bit over the course of the year, not to mention from pump to pump. Do not forget that below about 40F degrees, E85 is darn difficult to ignite - you need a really strong ignition system. So the "winter" blend is actually closer to E70.
I personally would not do a E85 conversion without using the the following; GM flex fuel sensor (one of which is the same as the Haltech sensor) true wide band O2 (not the cheaper "sort of" wide band sensor) true four channel ignition system with either AC/Delco D585 or Mercury Marine 1A coils an ECU that can use those input signals and ignition like a Haltech for example plus a full fuel system that can handle E85 from a coated tank to properly sized pumps, lines, regulator & injectors Like it was mentioned above, there is a cheap way and a right way. |
I love E85 and hate it as well.

E85 can have as low as 60% ethanol content.

Here is a start of pic of my setup on my Timeattack racecar.

It seems to me that it would be more involved then showing up with E85 in your gas tank and getting exempt from emissions testing forever. Has to be more to it then that?
