is 87 octane .. regular .. bad for a d16y8?
just what i said .. i've always used 87 octane .. i never thought anything of it until a read a post about a guy using boost with it on his d16 and he blew it .. what should i be using? .. and will i notcie a difference
also .. how bout my moms tsx? what should she be using

a tsx should run on nothing but premium
If you d is 100% stock 87 would not be an issue but if your tuning it in any way i would suggest 94, atleast thats what us car guys can buy in Canada at the Mohawk gas stations

Re: (vtecftw)
alrite .. i have like 90k on the motor its all stock .. but if i eventually turbo it .. i should bump it up to like 93? .. what would be bad if i ran 87 w/ a turbo?

Re: (ridin98civic)
i was curious about tuning .. from what i've seen it seems like crome is the best .. do you tune it yourself using your computer .. or does a shop do it? if a shop did it .. how much does that usually run?

tsx - 91
civic-87
the guy blew his boosted d16 becuase he was supposed to run on 91 he prolly had it tuned for 91 and ran 87, either that or it just detonated, his fault for being a dumbass, also if you EVER run spray go for 91

crome is a basic tuning progrman used to chip the ecu to be able to tune it, what i did, was i pulled a chrage pipe, loaded the stock fuel map, and drove to the dyno tuner, from then on he did a basic fuel map setup and similar to it, he charged me 100 bucks an hour took him 3 hours, and got a cd with dyno charts on it which are useless now becuase i have a diffrent setup

Re: (spork motorsports)
yea i've been doing some reading on turbo set ups .. and i dont know how i would do the tuning .. deciding on injectors .. and what size turbo to get .. it's pretty confusing to me right now
but i definately think if i spend 900-1300 on a turbo set up for my d16 .. its worth it instead of doing a swap

Re: (pjr710)
yup, a diy kit is wesome, i did mine for 500 bucks, and it was the first set up ive everdone,
t25 dsm turbo, greddy manifold, mandrel exhaust piping, fmic for supra, you can get a stock one from an srt4 for cheap these kids swap em out quick

Re: (pjr710)
wow, if you tune tune on the highest octane you can get at your local gas station on a daily basis. Here in washington the highest octane you can get at every gas station is 92, california is 91 so it just depends on where you live.

umm if you tune on 91 then run 87 you will detonate. Thats what cause detonation. the higher the octane you run the cooler the burn. if you run 87 and your timing is set for a higher octane the fuel with spark to early and run hot. that is what detonation is. (its kinda hard to explain so yeah)

no honda motor is designed to run on 87. they all run on premium fuel in Japan. The thing they are desinged to do is run unleaded fuel.

Wrong, in two ways. JDM motors aren't the same as USDM motors, and Japanese gas is rated differently than US gas.
JDM motors usually run slightly higher compression and make slightly more power. Ex:
B16A "SiR II" 10.4:1/168hp/116tq
B16A3 10.4:1/160hp/111tq
B18C "Type R" 11.1:1/200hp/134tq
B18C5 11.0:1/195hp/130tq
B18
Honda's taken the octane into account when designing USDM motors - if they say they're meant to run on 87 octane, they're meant to run on 87 octane. Look at the user's manual. If it says 87, you only need 87. If it says 91, run 91. Simple as that if you're stock.
And remember that Japan (and several other countries) rate octane differently than we do here in the US. Generally (and this is just a quick rule of thumb), Japanese gas is rated about 5 points higher than US gas. Their 92-93 octane (RON - Road Octane Number) is about equivalent to our 87 octane (AKI - anti-knock index), their 98 RON is like our 92.

Wrong, wrong, and sorta wrong.
Detonation is caused from too high of cylinder pressure/temps for the gas. The higher the octane, the more resistant gasoline is to spontanious combustion (detonation). Its actually the infrared head from the building flame and/or the very high pressure raising air charge temps that heats up hot spots, at which a gas with too low of octane will ignite itself.
Hondas in Japan were designed to use their slightly higher gas. Most civics were designed to run on 89 octane, but actually the d16y8 will run on **** gas, as its knock sensor senses good gas, and increases timing as much as 4 degrees. Note its the opposite of most knocks sensors, which retard timing with bad gas. Its because most people with stock civics are cheap fukcheads.

that is HORRIBLE incorrect.
d16y8's use 87. THe knock sensor does NOT increase timing, it only pulls away. You pulled that right outta your ***. and it will never pull more than 3* of retardation. A knock sensor does not read voltage, it produces it. It averages around 1.5v when in operation. If it detects a knock it puts out around 3v or so which sends the signal to the ECU to pull timing. How is it physically possible to advance the timing when it senses knock?????
https://honda-tech.com/zerothread?id=1181854
most civics are designed to run on 87,
Civic SI = 91
Civic EX/LX/DX = 87
All OBD2a/b ECUs knock sensors retard timing.
OBD2 B16's retard timing if detonation is detected when using anything less than 91. Same thing with Most factory turbo cars such as volvo t5's and s60/70's. The owners manual says 91 octane for peak performance and emissions. However it does not say anything about NOT being able to use anything less than 91. The OBD2 computer's knock sensor pulls up to *3 of timing to keep things on an even keel.
Now if it pulls 3* and detonation still occurs, then you will have more troubles.
JDM civics are NOT designed for higher octane you idiot! they have a conversion over there. THey're 92 is the same as our 87..
If your really worried about the rating of the fuel you use, deburr the piston, this should reduce hotspots. Get a few catch cans, cooler air charge, and possibly a higher flowing exhaust setup. The cleaner the air charge the less chance of detonation. On a turbo setup, elminate the PCV system completely and use an ENDYN type setup. oil vapors lower the octane, even when you use a closed loop system, vapors will still mix with the air charge.
If you want proof that these things help with detonation, either get a det can, monitor the Knock sensors output voltage, or check the plugs after a WOT run.
but again, on a D-series, 87.

Re: (spork motorsports)
Stock d16: run regular
Boosted d16: run premium
TSX: run premium
Oh and HiProfile, why the hell would anyone run anything but 87 in their POS stock d series engine? Are you retarded or what? Civic's and most Honda's are shitbox economy cars designed to run on 87. This isn't a Corvette or Cadillac we're talking about here.

i agree with most of the guys.. stock motor run 87 its cheaper and your car is designed for it... if you go boost definatly swithch to 93...
... i personally use 93 on everything ..it burned better and it last longer

Re: (ek forever guy)
neither is using a fully synthetic oil and changing it often, but it cant hurt if your willing to pay a bit extra. I had a d16y8 with only a short ram intake tuned on 92 octane with crome and it made 129hp and 97 fl/lbs of torque to the wheels. Thats more than honda rates that motor at to the flywheel.

yep. if you boost it i would raise the octane. wouldnt want any knock

damn .. so if i tune my stock d161y8 .. i can get that much power to the wheels? that doesnt seem possible
