i just got my car and dropped a b16 in. stupid me put 87 instead of 93. dropped it a few times and heard knocking. i filled it up with half premium and the other half is the 87 i used. whats the chances of permament damage? i know the knock sensor is good until 5k but i've gone to 8200 a few times without knowing i used the wrong octane. the car runs ok now, less vibrations and such. been drivin under 3 k when i found out. this topic been covered many times and yea i used searched but nothign came up for b16 that i wanted. help! octane booster good?

 

you'll be fine just fill up with premium on the next fillup

 

^^^what that guy said. No worries.

 

cool. hopefully nothing will happen..... hehe

 

my problem is similar, except I've put my b16 in and already have a half tank of 87 octane, I guess I'll fill up with 93 and add octane booster, is that what I should do.

octane booster doesn't really do anything unless your tank is almost empty. A full bottle of your average octane booster in a full tank of 87 would up the octane by .1-.2. I wouldn't expect a stock b16 to knock on 87 in the first place though.

 

runs like *** and knocking. its a jdm sir2 b16. not the usdm b16a2 if theres any dif. which i believe there is.

 

You could always drain the tank if you are concerned about it but just baby it through this half and half tank get it damn near empty then fill up with premium and you should be good

what brand gas? recently i've found my car hesitates a lot on bp gas, but if i fill up at exxon, my car is a lot more responsive.

 

citco brand and the premium i put in is petro brand.

 

Its funny cuase I drove a NA b16 and I felt like it had no power. Hell its not that much quicker stock for stock.

If you dont have an answer to his question then dont post.

Back on topic- try searching for dyno graphs of d16z6 motors. Should be able to tell from there somewhat.

 

i run 87 and theres no problem dont worry about it just put 91 next time if your that worried about it

 

if you want to drain the gas out, disconnect the return line from your fuel pressure regulator, connect a longer hose and stick the end in a gas can...start the car and let it idle... the gas will come out pretty fast.

 

and again im with stupid^^^

 

^^^That is how we drain the gas out a turbo car on the dyno if they want to tune on race gas. Pumping it out of the system does seem to work pretty fast and hell it isnt a lot of work.

 

just stay out of vtec till the next fill up...it shouldn't knock below 6K rpm even at full throttle. put a large "premium gas only" sticker on your gas cap.

 

yeah, i'd just keep it out of vtec for ahwile

 

if you are so worried, put in 2 gallons of toluene and that will boost your octane up to right where it needs to be. I run a b16 2nd. generation with 91 premium (CA premium that is) with 2 gallons of Toluene everytime i fill up. Octane rating is at about 95.5

 

i dont think that b16's requires premium fuel. i think its more of a psycological thing

 

theres your answer, the JDM SIR2 b16 engines were orignally "tuned" on 100octane fuel in Japan. I guess 87 is on the low side.

 

i was told the jdm b16 does. not sure about usdm ones. i am running a jdm

mine is a JDM B16a2 by the way

 

i have jdm b16. and yes i know its on the low side. haha. i will drian the gas out tomrow when i have time to. which line is the return line, top or bottom from the fuel pressure regulator?

 

I keep hearing that it really doesnt matter.

I dont know what to believe in any more
