The car is definitely running very lean at the moment, especially WOT as the car can correct up to 25% during idle/cruising but it will take a while for it to apply that to WOT fueling, and on top of it the injectors aren't big enough to go full throttle.

I would estimate that you'll be doing permanent damage after a few pulls.
Lean burn. Turning the tops of the pistons into silly putty.

Which is why I asked in advance. But I guess there ya go for stupidity. Never trust internet trolls. I have barely driven and not done any hard pulls yet so I guess thats a saving grace. Time to drain the tank and put some 93 back in it until I can finish the build and get the rest done. I love how no one says, don't do that until xyz is done until after you do it and even ask people in advance. So what all do you need to run E85 well and realize some benefits (without going full twin turbo at this time)? Injectors? E85 sensor kit? what else?

You got your answer in posts #2 and 3. You need injectors. Post #2- Bythabay (Eugene) is a master Ecutek tuner. Contact him, he can tune it for you without the need of the ethanol sensor.

lol you'll read replies by internet trolls on who knows what site, but you won't read legitimate responses in your own Z forum thread?

What the hell are you talking about? I asked and all the post up to the were about how I changed this or that and I am running fine. Not a single response given was remotely good until the first guy said on hell no. You need to learn to read JARblue. I screwed up by assuming that no negative responses to a straight up question were a green light and I was woefully wrong. I learned my lesson. But don't talk trash to me like you had some good answer I didn't respond to. You are no better than a troll right now.

Now does anyone have any good advice on how to drain the tank? I have been able to siphon it to about 50% but the anti-siphon device is now getting in the way of making much progress. Any good advice on this subject is greatly appreciated.

The tank is saddle shaped on the bottom for driveshaft clearance. You won't get all of the fuel out unless you open up both sides. To open up the top of the tank. You have to in behind the seats. Don't know if you want to do this or not.

Thinking of another way. Behind the right seat is the fuel pump. You might be able to disconnect the fuel line and put a hose on the end of the fitting. Once you do this. You can turn the key on, and let the fuel pump do the work.

Great advice for sure Rusty! Worked like a charm. I am already empty. 45 mins vs 3 hours of manual pumping...You rock!

So regarding injector sizing. I see lots of different sizes on injectors being referenced in this thread alone. Is there a right or wrong size to increase to from stock? If I were to change to 1000cc or 1500cc injectors would that cause a problem on pump gas (93)? Ultimately I would like to be able to run E85 for track days or performance and 93 for general driving. I have already been tuned on 93 for the setup I currently have, but I am about to install the Berk test pipes this weekend, which I assume will require additional tuning and so I would like to get 2 maps done when I have it retuned. That being said, I know I will need to go get some injectors then and I am trying to learn more about the appropriate sizing for now and possibly future expansion. Down the road I will eventually be installing Twin Turbos (Most likely the AAM kit from what Houston Z aka SZRPro is recommending) and want to make sure that I am not wasting my money now and have to purchase different injectors down the line. My apologies if I am showing my ignorance of the subject but I come from an older era where I worked on Chevy 350s and Holley carbs type setups...this is the first fuel injected car I have ever tried to work on.

Also what advantage does the lex fuel kit from SpecialtyZ give you if its not needed as was earlier suggested...Injectors and a tune on e85 if read correctly.

Hello pot; meet kettle.

I'm talking about the 2nd and 3rd responses in your thread, which I have quoted for you again below. You need E-85 fuel, upgraded injectors and a tune. There are also optional flex fuel solutions available. And yet, based on those responses, you decided to just put E-85 in your stock car, completely ignoring the need for the other necessary upgrades (i.e. a tune and injectors). What on earth made you think that would be ok???

I think Facebook might be a better resource for you. I'm sure you can find someone to tell you you're doing it right regardless of the facts. Alternatively, you could reach out directly to ByThaBay since he is quite knowledgeable and obviously willing to help. The choice is yours. I recommend choosing wisely

There is a dyno sheet if you scroll through, the car made 310 whp.

Specialty Z offers a flexfuel kit that would make it much easier, but you can have separate 93 and E85 maps and just switch, but you have to run it way down low before switching w/o that kit.

I would stay away from the AAM turbo kit. People on here have had issues with the kit. Where the turbo's are located at. They don't drain oil very well. Best bet would be going with either FI or BP turbo kits.

Rusty,

Your helpful information is really starting to infringe on my ability to troll. Please stop.

Warmest Regards from my insides,
