Difference between B16A1 and B16A2

I just want to know what the difference is between the b16a 1 and 2 !! And if they will fit tha same mount in the car... (Speaking theoretically)

Well the b16a2 as about 10 or so more horse power, not really sure why. Head flows better? I have no idea, but would like to know if someone can answer that.

And the b16a1 has a cable tranny, while the b16a2 has a hydro tranny. if you have a fourth gen, which I guess you do, the b16a1 will go in easier, since fourth gens also have cable trannys. 92 and up have hydro trannys.

The 10 or so extra horsepower come from the slightly higher compression ratio.

heres some b16 info for you.

http://tech.hybridgarage.com/tech/b16/index.html

the b16a2 runs OBDII while the b16a runs OBD0.

well, techincally the b16A1 came from the civic 1.6/VTi in europe. But is has the same power rating as the JDM first gen B16A. (In japan, there was never a B16A1, B16A2, etc rating, just B16A). The B16A2 is USDM from the Del Sol Vtec. The B16A3 is USDM Si. Both are rated at 160hp. The B16A3 is ODBII, the B16A2 is ODBI (unless there was a 97 Del SOl Vtec, that B16A2 would be OBDII if they made one). The first gen JDM B16A was rated at 158hp and was non-ODB, the second gen JDM B16A was rated at 168hp, and was ODB-I. The JDM 3rd gen B16A was ODB-II, same hp as 2nd gen. The reason for the power bump of 10hp in the 2nd and 3rd gen JDM B16A vs the JDM 1st gen B16A (and the USDM B16A2 & A3, the european B16A1) is that it has a 10.4:1 cr vs the 1st gen's 10.2:1. Also, the 1st gen JDM and the european B16A1 had a cable tranny. All others had a hydro tranny.

B16A's in Japan were never officially called B16A1 and B16A2 but they still get called it. (not just in US but in JDM countries like Japan and NZ)

B16A1 - 160hp. Cable tranny. Came in EF9 Civic SiR, EF8 CRX SiR and DA6 and DA8 Teg XSi

B16A2 - 170hp. Hydro tranny. EG6 and EG9 Civic SiR, EG2 Del Sol SiR, DA6and DA8 Integra XSi facelift plus EK SiR

The differences are B16A2 has OBD1 instead of OBD0 wiring, different rocker cover, higher compression, different cams.

HTH

so if i was doing ls/vtec i would want the b16 head right, opposed to the b18,s?

You can use a GSR or B16A head for an LS/Vtec. However, the B16A head flows better by 5.25% and also has silighty more displacement than the GSR head, 42.7 to 41.6 (the LS head is 45cc). An LS/Vtec with a B16A head would be 1832.17cc. A LS/Vtec with a GSR would be 1831.07cc. A regular LS is 1834.47cc.

Dude, we never got a Del Sol in America with a B16, you're probably thinkign of the 98+ Civic Si.

:rolleyes: Wow, this is something I'd never expect from someone with over 2000 posts.

I'm not a postwhore, if that's what you're tryin to say. The guy said Del Sols in in AMerica came with B16s...then siome kid thnks del sols have B16s for a while, which is wrong info.

actually integra the 94-95 Del Sol came with an option for the B16a3 motor. there were the base del sol, the s model and the del sol vtec which had the b16.

however eckoman, the b16a2 is from the USDM 99-00 Si's and the b16a3 was the USDM 94-95 Del Sol Vtec.

I'm not a postwhore, if that's what you're tryin to say. The guy said Del Sols in in AMerica came with B16s...then siome kid thnks del sols have B16s for a while, which is wrong info.

Dude, the Del Sol DID COME WITH AN OPTION FOR A B16A FOR A FEW YEARS. IT WAS CALLED THE DEL SOL VTEC, MANY YOU'VE HEARD OF IT. This is not wrong info, but fact. Ask Honda, go find a Del Sol Vtec and pop the hood. Regular trim Del Sol's had a D16Z6, not B16A, but the Del Sol Vtec trim (made in 96-97) had a B16A under the hood from the factory. It was not a mass produced car, but it was produced. Del Sol's in the us did come with a B16A....not all del sol's, but some, the Del Sol Vtecs. (I beleive the 96-97 Del Sol's came with the option for the B16A powered Del Sol Vtec)...I get so sick of people coming in here and saying things like this without properly looking up the info. There were 2 cars in the US released with a B16A...the Del Sol Vtec (B16A) and the 99-00 Si (B16A). Neither were a mass produced Honda, per say, like the EX, etc civics were. But they were released. Look up the codes, all the engine books, etc, all list the Del Sol Vtec as having a B16A as well as the Si. I can't believe someone actually came in here and told us "you're wrong, the del sol never came with a B16A, must have been thinking of the 98+ Si." Ok, besided that being wrong (The Del Sol Vtec had a B16A), the Si was not 98+, it was 99-00. Get the facts straight before you say them.

To crxlvr, you may be right about the exact codes, though I swear I remember it the other way around. I'll check out the codes when I get home tonight to see which one had the B16A2 and which had the B16A3. I'll post it tomarrow. I have multiple sources I can cross-reference there, so I'll check and post it tomarrow afternoon.

Aright, aright, relax man, a small slip-up and you go ballistic on me, chill out. The fact that I've NEVER seen a Del Sol with a stock B16 has led me to believe that they never came with that engine, even tough they do. MY mistake, you don't have have to burst into flames and shit like that.

Jesus, man you're an idiot. Talk about misinformation, you're full of it. 94-97 Del Sol vtecs had the 160hp B16A3, the Si had the D16Z6 and the S had the D15B7, now drive on through.

I did not know they were made up to 97 though, but here it is link (http://www.wabe.net/silum/97DelSolSpecs.html). 1997 Del Sol VTEC.

eckoman, the del sol's started the VTEC model in 94' and continued it to 97 when the car series died. I personally own a 94' with the stock B16A3 motor under the hood. (hydro tranny)

It's easy to talk shit over the internet huh??? Fuckin coward.

Hahahaha, you're all butthurt because you're wrong and got called on it. Coward, wow, that's a doozy, please don't hurt me mister E thug. If you were in front of me and you tried to tell someone that the Del Sol never came with a B16 in the states, I'd slap you upside the head, then maybe we could go have a beer once some sense started to seep into your cranium, but don't get all ghey and start trying to peice together some dignity via trying to insult someone, try this instead, "sorry guys, I was wrong, they did make a Delsol with a B16 in the states"

About the "sorry guys, I was wrong, they did make a delsol with a b16"..look back a few posts...it's there. IF I was infront of you,key word 'IF', but I'm NOT in front of you, what IS in front of you is a computer which makes you feel special when you talk shit to people on the other side of the world.

I still see no fuckin point in you insulting me like this, you're acting childish man. I was dead convinced that there were no stock B16 Del-Sols in America because I've NEVER seen one stock, but now I'm convinced there is since so many people mentioned it. I'm not trying to "piece together some dignity". It takes more than an internet forum to hurt my feelings.

Stop the shit-talkin, it's not making you look any better, all you're doing is making both of us look inmature here, altough I'm not really afraid of how people judge me on these boards, but I rather have a good rep than a bad one.

to late for both of you your both idiots jk..... hey maybe the saying is true maybe we do learn something new everyday. well i knew that but you didnt but now you do. :screwy: :sly:

what IS in front of you is a computer which makes you feel special when you talk shit to people on the other side of the world.
Sorry bud, I don't need a computer screen to fullfill my life correcting BS is not the highlight of my day, but it is funny seeing people like you who get butthurt over internet forum post, haha

I was dead convinced that there were no stock B16 Del-Sols in America because I've NEVER seen one stock,
Well then, maybe next time you try to spout off that someone is spreading some "misinformation'', you'll make sure you KNOW what you're talking about, and not spread your own brand of "misinformation" around, k?

but now I'm convinced there is since so many people mentioned it.
Or, you could just do a little research, or read around a bit before trying to sharpshoot someone else, it isn't like it was some ultrarare never heard of model that Honda kept under wraps.

So what are you crying about?

Stop the shit-talkin, it's not making you look any better, all you're doing is making both of us look inmature here, altough I'm not really afraid of how people judge me on these boards, but I rather have a good rep than a bad one.
You say "stop talking shit", yet lay out a tirade of your own, hmmmm...If you want a good rep, then as said before, don't try to correct people who are right.

So anyway, this is getting pretty boring, and not going anywhere, the question was pretty much answered, so time to move on.

eckoman, the del sol's started the VTEC model in 94' and continued it to 97 when the car series died. I personally own a 94' with the stock B16A3 motor under the hood. (hydro tranny)

Yea, I know...I was posting at 4am from a friends apartmen, I thought I typed 94-97, simple typo. Also, to crvlvr. I looked, you are right, I remembered wrong at 4am when I was posting (i regards to which car had what. I found listings for the Del Sol Vtec as having the B16A2 and A3. Maybe a misprint, but hears what I figure. Since the Si had an A2, I figure the OBD-I Del Sol Vtec had the A3, and the OBD-II Del Sol Vtec had the A2, which was also in the Si (OBD-II).

96-97 Del Sol's had B16A2's. The Si is obdIIb.

Aright, aright, relax man, a small slip-up and you go ballistic on me, chill out. The fact that I've NEVER seen a Del Sol with a stock B16 has led me to believe that they never came with that engine, even tough they do. MY mistake, you don't have have to burst into flames and shit like that.

Just because you have never seen one doesn't mean they weren't made. I knew they existed long before I ever saw one. It's not some special hidden tresaure car. It was a trim line of the Del Sol. Read a repiar manual, talk to the Honda dealership, it's fairly commen knowledge. It's find that you didn't realzine there was a B16A del sol, thats fine. You learn something knew everyday. My problem was that you said, and I qoute, "not a postwhore, if that's what you're tryin to say. The guy said Del Sols in in AMerica came with B16s...then siome kid thnks del sols have B16s for a while, which is wrong info."
You are the one that tried to get all over me about it, tell ing me I was wrong, and that because of my so-called wrong info, "then siome kid thnks del sols have B16s for a while, which is wrong info." If you didn't expect me to respond to that in such a manner, then maybe you should have looked up the info and double checked to make sure before trying to know me down. Then you would have realized on your own, that I was correct and you were wrong. It's okay to be mistake, but don't go trying to snipe me off, thats rude, be more polite in your demeaner. Also, don't go telling someone they are wrong without checking your info out first. Just because you haven't seen it doesn't me it doesn't exsist.

96-97 Del Sol's had B16A2's. The Si is obdIIb.

Ahh, okay, so I was right then, pretty much. I knew I have seen a B16A2 stock under the Del Sol's hood, but it was the last year or so, a 96 or 97. That would be why. Yea, as I said, the Si is OBD-II, but isn't the 96-97 (or is it just the 97, I can't remeber the year OBD-II started, it was one of those) Del Sol also? That was my thought on why the 96-97 Del Sol's had the B16A2, but the 94-95 had the B16A3. Because the B16A3 is OBD-I, and the B16A2 is OBD-II. That's why the A2 is in the later year del sol's, cuz they are OBD-II, just like the Si.

OBD IIB slightly higher on the emissions teir. But I believe the only difference is in the ECU.

ahhh...arent motors fun?!?!?! lets let it bring us together...no need to argue over it...

quick question though, maybe this was mentioned if so sorry: what engine came in the 92 -95 civic si's?

also what engine is in the 94+ gsr's? did both of these cars have OBD1 or 2? thanks to who ever can answer.

OBD IIB slightly higher on the emissions teir. But I believe the only difference is in the ECU.

Yeah that makes sense. This explains why the later gen del sol's had the same b16a2 code as the Si.

92-95 Civic Si had the D16Z6 and the GSR's had the B18C1.

OBD levels are as follows:

OBD 0 = pre 92
OBD I = 92-95
OBD II = 96-98
OBD IIb = 99+

and the d16z6 is an sohc right? also that is the same engine that came in the ex model of the same years? what else was the b18c1 put in? once again sorry for asking so many questions...

and the d16z6 is an sohc right? also that is the same engine that came in the ex model of the same years? what else was the b18c1 put in? once again sorry for asking so many questions...

The D16Z6 is a SOHC 1.6 liter vtec motor, it is the same engine that came in the EX of the same model years, it also came it the 94-97 Del Sol Si (not the Del Sol Vtec) as well s the 92-95 Civic Si Hatch (and the EX). The B18C1 is a DOHC, 1.8 liter vtec motor. It only came in the 94+ Acura Integra GSR. There was a JDM B18C motor, similer to our B18C1, I think it had a little higher compression, and it had a little more hp. The Integra it was in wasn't called the GSR over there, think it was SiR-II or something like that, though I could be wrong on the JDM name. Also, I responded to your pm. :bigthumb:

and the d16z6 is an sohc right? also that is the same engine that came in the ex model of the same years? what else was the b18c1 put in? once again sorry for asking so many questions...
Yes it is the same as the EX motor, and also the Si Del Sol. The B18C1 is unique to the GSR, but in Europe there is a 1.8 Civic that has a B18C4, which is the same as the B18C1.

OBD IIb = 99+
:wtf:
what's the diff between that and OBD II?

Not sure of the exact differences, but I would guess different monitoring emissions on the ECU's part, and different maps that deal with the emissions. Physically the difference is the location of one of the plugs. Here you can see the diff...

http://www.hondata.com/images/stackof4ecus.jpg

OBD IIb
OBD II
OBD I
OBD 0

not much ricochet, there were small upgrades to devices and the ecu's ability to control them, enough of an upgrade to warrant the 'b', but not enough to warrant OBDIII.

:wtf:
what's the diff between that and OBD II?

Hell if I know, I've never heard of it before this. Never seen it listed either. I am gonna go go to the Honda dealership, play off like I am interested on the 99 Si in their lot, and find out exactly what is what...lol.

(12:04pm) Edit:Well...looks like jcrv answered our question on some of the difference, lol. I wonder why it's not listed anywhere? I only see it listed as OBD-II, not IIB. If I find anything moe out, I'll post it.

Sorry bud, I don't need a computer screen to fullfill my life correcting BS is not the highlight of my day, but it is funny seeing people like you who get butthurt over internet forum post, haha

First of all, I'm not getting "butthurt", second, I'm not crying about anything, if it was anyone crying here it would be you seeing as how YOU'RE the one acting like a kid.

Dude, just stop already, you're just fueling the fire, it's useless, we're arguing over nothing. Take it to PM if you want.

Dude, what the fuck is wrong with you??? I'm tryin to end this shit and you're fuckin sparkin it up agian like a fuckin retard that wants to prove he's big and bad or something.

Ok, so now you want to start cussing at me, and trying to sound like a victim, good try. No, I am having fun, I already said it was over, it doesn't need any further response from you, yet here you are, blah, blah, blahing all over my screen. If I was trying to make you feel like a turd I would, and you don't need to try to tell me where to take it, if I cared enough to PM you, I would.

Chek your PM box.

Chek your PM box.
Look dude, this thread is sooooo far past your petty bullshit that I barely remember it. Suck it up, and drive on, alright. And as for your bullshit PM trying to say some dumbshit about "going nazi", or whatever the fuck your poor excuse for a delusioned mind came up with, cram it up your ass. I could careless (much less know) what ethnicity your are, you got drop kicked on your ass because you are a tard that made a fairly ludicrious statement, and not only that, you were trying to say that someone who was right was wrong. So take your deluded "poor me" ass home and jump in the shower rinse off the persecution, and come back with a clear head before you actually piss me off.

There are del so with b16a in them stock. You did not know they mad a del so that came stock with b16a. Look it up man
