ok so first of please dont tell me i should have went with lower compression pistons,or i should have done this or done that, its just a car ive been toying around with...something a little different....so i have a 92 eg hatch with a built and boosted b18c1, the only thing stock in the engine are the sleeves, it has je 13:1 pistons...my question is what would be the best fuel to run in this engine with such high compression pistons? the cost of the fuel is no matter, just wanting some input on the best fuel would be..thanks in advance

jbpnoman

Why did you put "boosted" in your title? Are you actually wanting to boost the car?

Did you buy the car or motor like this, or did you build/have it built yourself?

Run whatever fuel it's tuned to run on. At that compression, it should either be tuned for 93, or E85, but for all we know it was tuned to run on 114. There is no such thing as a "best" fuel. Higher octane just means higher detonation resistance. If you don't know what fuel to run, you have a lot to learn about building quick cars.

Just what jbpnoman said, at that compression holy ballz the only fuel I would consider is E85 unless you want to pay $100 for 5 gallons of race gas all the time...

What fuel was it tuned on? Or is it tuned...

evilpenguinking

i built this car from the ground up, the car is currently boosted and at my tuners shop...everything is ready to go..we are just having trouble on which fuel to decide on..ex, vp110 race fuel, pump e85, e98 out of the barrell, c16..

evilpenguinking

it is currently not tuned...my tuner has already installed neptune on the ecu though...

evilpenguinking

and when i say boosted i mean it has a full turbo kit on it..

jbpnoman

And your tuner doesn't know what kind of fuel to feed it?...Sounds like a top notch guy you have, there.

Do you even know what you want to do with the car? DD? Circuit track? Drag? If you're planning on DDing it, and if E85 is readily available, replace your injectors and fuel pump and get it tuned on E85. If E85 isn't readily available...just stop now. You're going to shatter those sleeves. If the car is going to be a track-dedicated car, FIRST make sure whatever class you want to run in allows it, then tune for the highest octane racing fuel you can get at the tracks you go to.

evilpenguinking

well he said e85, just wanted some more input from some members on hondatech just to see if anyone here says different...i plan using it for drag..

evilpenguinking

and stowne78, price does not matter at all on the fuel...just wondering if there is something a little better than e85 or e98 for detonation..

jbpnoman

C116, or AvGas. Period. C116 is easy to get your hands on.

evilpenguinking

ok awesome, thanks jbpnoman, never heard of avgas...do you know a website that sells it by anychance? just wanting to look at it..

jbpnoman

AvGas = aviation fuel. More information. It's a whole different world of fuel, and you generally need either a license, or a hookup to get it. 100/130, or 100LL are absolutely AMAZING at preventing detonation, but they're expensive as as hell if you can get your hands on it in the first place. I had the fun of ******* around with 100LL once when doing a street tune - the difference was amazing.

Just go with C116 or C114. You can pick it up by the 5G mini-drum at most Sunoco stations, and it's fairly common at race tracks. Just make sure you're ready to deal with the hell that leaded fuel is going to do to your O2 and wideband sensors.

evilpenguinking

oh wow avgas would be amazing...i think what im going to do then is have an in-cabin switch and have tunes for both e85 and c116 so i dont always have to use the race fuel..im just a little weary about pump e85, so i bought a tester from summit racing to measure the consistency..

why the hell are you running such high compression?

jbpnoman

The high compression isn't a problem...the high compression with boost on stock sleeves is. Yes, it's stupid, but I was leaving that alone.

You'll need a little more than an "in-cabin switch", OP.

evilpenguinking

@doood, honestly just because...ive got the money to do it...just wanting to try it out...whats the worst that can happen? my engine goes boom? lol then it will be time to build another one.

evilpenguinking

it does have replacement iron sleeves, bored out to 81.5 not looking for any ridiculous amount of power..

jbpnoman

I have a strong suspicion OP is pipedreaming, but I'm going to indulge him.

First off, high compression with boost on stock sleeves is stupid. Stop that.

Second off, a cabin switch to change between fuels is a lot more complicated than you seem to think it is, especially if you want to use E85 as one of the options. You'll need two completely different tunes for the different fuels, and on top of that you'll basically need to run open WG on the street tune, or you're going to absolutely shatter those sleeves. That's not even getting into the different requirements for injectors and fuel pump flow rates.

Third off, leaded fuel can wreak havoc on a car. Your cat will be absolutely fried, and your wideband and O2 sensors will be fucked right up the ***. None of those are cheap parts to replace.

Fourth, and finally, this is probably the worst pizza I've ever eaten. I shouldn't order from these guys again.

evilpenguinking

did i ever say it was a smart idea?? ive got alot of money and im just messing around with different setups...i have 2 other golden eagle sleeved blocks, im not worried about any type of money situation, and i just want to see how this setup turns out...and lmfao about the pizza

Ash J. Williams

you COULD run O2 sensors with avgas, but it is not cheap, and you would have to clean the sensors often. it also isn't good for you, at all.

jbpnoman

If you don't care what happens to the motor, why do you care what kind of fuel would be the correct fit?

evilpenguinking

just wanting to know, but youve already answered my question

You're talking like you're Donald Trump but are running stock sleeves for some reason. Can you give us the reason as to why?

just use pump e85 and call it a day. you are making this thread too complicated -_-* E85 trumps race gas when it comes to using it for a street car or track even, it would be a waste of $$$$ to run race gas. Tune the car and report back to us. Search for the username "Muckman" he has a 13.5:1 turbo build he did, not on stock sleeves though.
