I have a jdm b16a in my 95 eg. i bought it 4 months ago all is good. i just wanted to know if it was the b16a off the del sol. it has a p30ecu its a obd1 sir 1 i belive all i know is that it came off a jdm 95 civic i guess. it has 170hp. so its should be the newere one. it also had lsd tranny. it also has two holes on the front of the tranny like for a extra motor mount. the only tranny that i have seen online with those 2 holes going vertically down is the b16b type r trannny. gas is getting expensive and i heard that del sol b16a need premium, so thats what i have been putting. if it's not a del sol motor i can save my self some cash and put cheaper gas. thanks any help is appreciated.

jdm b16a on 87 regular unleaded right here, no sign of detonation!

 

cool cool that's what i thought too, when i swaped in my motor it had half a tank full of regualr unleded gas. and it drove like normal. i thouhgt maybe it would abck fore or something. my friend ahd an evo n his dad filled it up with the cheap gas one time. it was backfireing n sputtering. so im guessing its not a del sol motor or it not noticeiable if ur damging it. thanks for the post any other suggestions.

 

either one of these will run fine on 87 oct, Delsol DOHC USDM B16a1 or a3 P30 / Integra Xs-i DOHC JDM b16a PR3 / or 99' Civic Si DOHC USDM B16a2 PR3, all of there compression ratio is under 10.5cr.... The only one that i would run with Premium is the B16B Civic Type R, it's got a compression ratio of 10.8cr closer to the 11cr's, someone please correct me if im wrong.

1.) A B16A is a B16A. Del sol or civic chassis doesn't matter. Same engine. 10.4:1 compression, and 170hp (If it's JDM). The USDM B16A2/3 (Del sol VTEC or 99-00 civic Si) is pretty much the same as well...IIRC 10.1:1 compression and 160hp. They both require premium. For many reasons. Compression isn't the ONLY thing to take into account. The ECU advances timing a certain amount to be able to get good gas mileage, and put out a certain level of emissions. The manual says that you can put in regular gas....but you will notice a decrease in power (more on this in #3).

2.) lol dude...cmon. Usually, you fill up around 10 gallons in a civic. You pay 20 to 30 cents more for premium, making a difference of $2-$3. Be real. No matter how high gas prices get, you're still only paying a $2-3 difference between regular and premium.

3.) The amount of fuel needed to prevent detonation on a B16A under normal (non highway) driving conditions with 87 octane is increased. So you use more fuel since the ECU has to retard timing more, and keep the knock counts down. So your whole theory of saving money goes flying out the window.

Just put in premium...it's not that big of a deal. I used to put in 87 or 89 in my GSR just because I wanted to kinda experiment with it. It knocked like CRAZY with 87 octane. With 89, it was pretty normal...but I drove like 95% highway, so my fuel economy wasn't really affected. I just ended up putting 93 in it again because 87 wouldn't work...and 89 was only 10 cents cheaper. The car made much nicer power on 93. The ECU was able to advance the timing properly. The car made noticeably more top end.

The gas mileage difference for me was negligible..but again, I drove about 95% highway.

 

alright cool sounds good, i guess i will keep running premium. i never did the math of how much more i would pay for premium and it's really not a lot of money. i fill up with $30 on premium at 76gas in so cal it's $3.29 a gallon and i get like 9 gallons b4 my tank overfills. i get 360 miles to the tank. and thats both street n highway. thanks for your help guys.

 

You get 40mpg with a B16A? Iduno....

 

yea i'd think you would want to use higher octane gas for a higher compression motor anyways

 

i agree 100% with b serious. i have always used 93 and always will.

 

i have a y8 and i'm getting 18 mpg, sux, an d don't know why

What CELs do you have?

 

B Serious is entirely correct!

lol had to do it

 

ya dudes i get 360 miles per tank. and when i fill up with $30 on 91 premium. it never hold 10 galons. it stops at like 9. somethign then if i keep going it will over fill. i get alot of miles and i dont know why but it's all good. i also have code 10 "intake air temperature sensor" and 36 "traction control found on JDM ecu's"
i dont think these codes mater. i always get 360 miles i sometimes get like 340 but i never get more that 360.

 

What is the trans code? Del Sol B16A's came with a Y21 trans (best b series trans imo other than jdm type r) and the swaps usually come with the gold colored shift linkage.

that's probably because your tank is not fully empty when you refill. the tank should be 11.9 gal

lol you DEFINATELY need to fix the Intake air temp code. It's a critical sensor for the speed density fuel system that honda uses. Your ECU is "guessing" air/fuel maps. There's a variable missing if you have a IAT sensor problem. You really need to fix it.

 

ya i tried to locate the iat sensor, but i couldnt find it. i know where it's located. it's been so long since i had the stock airbox on this is my 3rd swap. and since my local sho "Autolink" closed i have to find somewhere else to tka eit. as for the tranny i have to check the code i will post that up later.

 

i couldnt find the code for the tranny isnt it a sticker on the side it says the y something. here is a pic of the mount holes i was talking about.

 

in the picture you posted it looks like thats where a VIN plate should go...Like maybe it was removed...that is if its a US trans...
I may be wrong tho

looks like someone has a stolen tranny hope the police don't find you...

 

yeah that's where the vin plate went. as to the motor itself, if you look at the number on the block, under the B16A stamp, it will have a long number. if it starts with a 1, it is an sirI motor, if it starts with a 5, it's an sirII motor.

It's either on the intake snorkel or on the intake manifold.

If it's on the snorkel, it will be the only sensor there. If it's on the manifold, look for the white sensor being held in by 2 screws. IIRC, one of the wires going to it is red/something.

You sure that's not 360 kilometers per tank?

 

OH MAN. you need to be running 91 or 92 depending on what state your in. especially when your reving it to 8200 with that p30 ecu.

The increased octane is used mostly for acceleration from a stop at low RPMs so that the ECU can keep the timing advanced without knock. It is used for high RPM operation, but with stock timing, and boltons, the octane at high RPM operation is not quite as critical as low RPM operation.
