is it possible what would have to be done?
raise compression , forged internals, tuning, etc....etc
man I need to do that I live in the middle of corn country man
might have to mess with ignition system maybe
You need a stainless tank, all new lines. more sensors, bigger injectors like stated. a wicked tune
Talk to Skunk he's swapping over.
oh ok thanks

you don't need a stainless tank, you don't need any more sensor than what the car came with except a good wideband since you are having to retune the car a bit, more or less adjusting the injector constant.
If someone is going E85 the best thing to do is change any of the rubber lines to a steel braided line, make sure your fuel pump can handle the increased amount of fuel it will be pumping, jump up to larger fuel injectors, and retune it for the e85, after the first half a tank of E85 or so, change out your fuel filter to a new one.
We've done it for many cars. And actually there's quite a few 70's Datsuns, a handful of Evos and DSMs 2 or 3 240sx' also some Hondas the shop I'm connected with has "converted" to E85. Most of them with the biggest changes being just the fuel injectors and tuning.
Haven't had any tanks developing holes, haven't had any rubber fuel lines leaking, no metal corroding and a in the case of the Evos making over 600hp.

my brother switched over to e85 on his DSM, and it made a world of difference. took care of knock completely, enabled him to run higher boost. Just have to work with the tuning, but we did 390awhp on 17 psi and just upp'd the timing 2 degrees. A decent start. He has upraded the fuel lines(obviously bigger), runs a intank walbro, and a bosch 44 inline pump to handle the demand.
He also had his fuel rail anodized as to have a protective coating on the aluminum.
Now, he told me about a test that was done at his work (briggs and straton) on what E 85 did to a normal gas engine parts(fuel line, carb). In sitting for 2 weeks, it ate through the primer bulb, and left the carb all pitted up(looked like rust) and not sure what was left of the rubber line.
Just do alot of research on the web, there is tons of great info out there. I will see what i can find and post back.
never had any weird pitting problems over here.

ive never had a problem running mine on it, but i never put in a full tank: a half at the most, and every other week if i do. i have tripped the o2 sensor once i jus ignored for a bit then put some regular back in and it went away. granted my car is stock (99 z) it handles it jus fine. but if your goin run it all the time make sure your fuel system can keep up, change your rubber lines, and tune it.
that is what a uncoated aluminum carb bowl looks like after 2 1/2 weeks of e85 in it.
^^^^ I would expect pitting over an extended period of time, but only 2 1/2 weeks? Ouch!

"Youth in Asia"...I don't see anything wrong with that.
I guess that's why we dont' use carbs?
Yes it is an ignorant statement, but however one picture verses numerous cars at the shop here running big power and E85 not having issues with it, some running for over a year and a half going on two years with some simple modifications tells me otherwise.

Fuel rails are uncoated alminum. Uncoated aluminum is uncoated aluminum no matter how you look at it. Is there any Flex fuel vehicle out there that has a aluminum fuel component?
He just showed me the picture and told me what E85 tests have be done at his work by the r&d department & their surface engineer. I will get a list of what else e85 will corrode. He talked alot with the coating engineer and asked about running e85 and running a plain alminum part with e 85 ,the guy just laughed at him.
Probably not a problem by you in las vegas, but E 85 causes hard starts in the cold, and hope it dont get gelled up. In the colder climates they switch to a different blend, it is a lower octane rating and something like e -70 it is called.
Just letting you know what my brother has done to covert to e85 and the research he gathered. Yes it has enabled him to make alot more power and is a cheap alternative to race gas. Glad to see the J body people finally researching into running it.
On my brothers dsm, he had his fuel rail anodized. He didnt want to take the chance of running a uncoated
aluminum part knowing the corrosivness of e-85, then clog up his 1600cc injectors and there goes his stroker motor on his dsm. Cheap insurance.
just an FYI any 03+ cav with vin code 6 is flex fuel
all vin code F's are not supposedly but i dont see the differences in fuel systems

It's not a problem of the fuel gelling up. They do switch to the E70 for the winter time for the same reasons as why in the US we run E85 instead of E100. The comes in handy like lighter fluid when you're outside grilling. Once the fire is going a bit, the heat will cause the rest to take off.
The flashpoint of 95% (theoretically without a molecular sieve this is the highest concentration of ethanol that can be made... Everclear maybe?) is around 62*F (17C). Gasoline's flashpoint is -40*F (-40C). So you mix the ethanol with gasoline to help in colder weather. You can get the gasoline to ignite. The other purpose for gasoline in the Ethanol is to make it unfit for human consumption.
Ethanol won't hurt aluminum. It's when you get a little water into the mix it gets highly corrosive. And it's almost gauranteed that you're gonna get some water in with your ethanol (see above about highest concentration of ethanol). So perhaps a water separator on the fuel line would be a good idea to help protect your aluminum pieces.
what is that aftermarket venom fuel rail made of? it's nice that e85 burns cleaner. with a polished up engine, you would get very little carbon build up. also if your worried about water in some e85 put a bottle of heet in the tank.
Or better yet to could not run e-85 not have to convert anything and run run alky injection! It will do far more for cleaining the internals of your egine than running e-85.

what happens when your alky injection fails? ^
You can make more power on e85, then pump gas and water/meth/alky injection. And then you dont have to worry about a injector clogging up, a relay not working, or a wire coming loost on your injection set up.
I agree with sho0ff 100%. My whole deal with the uncoated aluminum coming in contact with e 85 isnt a major issue, just a little extra protection never hurt anything.
That seems easier then doing a ton of reading misinformation, redoing your entire fuel system, finding the right size injectors, tuning for them ect. The list goes on and on. Plus you still have to worry about the modifications you make to tyhe fuel system, parts failing eiher way. So as far as I see your point is moot.

misinformation? All my post says is the results a person got from testing e 85 againest un coated aluminum , my bro's dsm has a coated fuel rail and he made a big improvement in HP switching over to e 85. Ya it had some work involved(new lines, extra fuel pump, big injectors). But his set up wasnt even close to being ultilized on regulaur 93 octance and e 85 was his next option or run race gas everyday.
Everything in this post is correct. Listen to spyhunter, i seen some of the work coming from that shop, and taking in consideration making 400+HP on a 2.4l motor means he knows his stuff.
Ya it might seem like a lot of work to you, but it might seem like easy work to people like spyhunter looking to push them motors to the limits and maintain a margin of safety.
I know how alky/water/meth injection works. I personally wouldnt want my car tuned to rely on a add on injection system to keep me in the safe zone. I ran water/meth injection b4, not saying it doesnt work. I used it to cool down my s/c and it worked great for that.
