I'm only posting this info here (and in the FAQ) as a reference for those that might want to get a B18A engine and don't know what it looks like.

I would love to fool around with those carbs and manifold. They do fit the A20 right?

carotman

From the JDM parts catalog I have here, the intake manifold gasket is really different from the A20A/B20A ports.

It might be similar to the A18A head.

i'll get a diagram of the B18A intake in a couple of hours

So basicly thats the big sister of the A18A

Just like the B20A is to the A20A

How odd, square ports.

How about the bolt holes are those simmilar?

Yes, please post any pics / diagrams you have.

Here is the intake manifold (sorry for the big picture but the bigger the better they say!)

B18A intake manifold (http://carotman.no-ip.com:8888/3geez/b18a/B18A_Intake.gif)

B18A Carbs(2) (http://carotman.no-ip.com:8888/3geez/b18a/B18A_Carbs2.gif)

Here's the 2nd gen Prelude ES engine (I mixed it with the A18A in my 1st post)

ES Carbs(2) (http://carotman.no-ip.com:8888/3geez/b18a/ES_Carbs2.gif)

Here's the B20A3 (Prelude 88-89 S, Dual Carb) engine carbs
B20A3 intake manifold (http://carotman.no-ip.com:8888/3geez/b18a/B20A3_Intake.gif)
B20A3 Carbs (http://carotman.no-ip.com:8888/3geez/b18a/B20A3_Carbs1.gif)
B20A3 Carbs(2) (http://carotman.no-ip.com:8888/3geez/b18a/B20A3_Carbs2.gif)

The ES engine seems to use a similar but sifferent kind of manifold setup. The carbs do seem to be quite similar if not the same.

The B20A3 seems to use a very similar intake port design. The gasket seems to be upside down if you compare it to the B18A (turned 180 degrees). The weird thing is that runners #2 and 3 are connected together...


That's all I have that seems pertinent. Do you need any other diagrams?

08-15-2005, 08:45 AM
Hmm, strange... I always just assumed they would be the same as the ET/ES engines because of the same/similar dual carbs.
I'd like to have a B18A block and mess around with. Shorter stroke on them :)

oh by the way, a little offtopic but how do you get the diagrams out of the program like that? and in fullsize

carotman
08-15-2005, 09:53 AM
The B20A and B18A heads aren't the same. However, the blocks seemm to share the same headgasket so it could be possible to use the B20A head on the B18A block I guess. The only advantage would be that it could rev higher whitout destroying itself. Without a Vtec head, revving higher with an agressive cam means a shitty idle :D. (bah, who cares hehe)

For the diagrams, catch me on MSN, I'll explain it to you. Basicaly, you right-click in the window and it should enlarge. Then choose "edit" then "copy"

Is #26 on the first B18A carb diagram a TPS ?

carotman
08-29-2005, 10:11 AM
Yeah, it looks like a TPS of some sort...

I don't have the exact description in the parts catalog (it's in japanese) However, I will compare the part numbers with existing ones to see if it matches with something.

OMG the B18a didnt even come in the JDM 3 gen accords or ever for that matter. The JDM engine for the 3gen accord is the B20b " not to be confused with the 88 - 91 preludes B20b. lets break down engine code reading....

Firs there is the series number: B
then there is the Cubic centimeters converted in Liters: 18 "hince a 1.8L"
the Letters after that signify the version. and or "Emission changes or revision"

now we have the JDM 3gen engine . the B20b
signifiying that it is a 2.0 liter. that is why almost every part will exchange from the USDM B20b prelude engine.

also in the picture to point out differences. the B20b uses the same exaust and intake manifold as the A20a3

Im not flamin anyone, and if i am wrong without a doubt i will apologize. It is just that i want my fellow 3g's to have a better understanding of our cars.

Legend, the pics is really a B18A jdm from accord 86-89.
And we have the B20A too. Both engine look the same and came from the accord 86-89.

Not to be confused with the B20A from Prelude 88-91.
D16ZC from Integra look similar to the B18A. But as the B20A, don't be confused by both engine!

Look a this link. I did my research and I find all my answer. I did this page for reference 3 weeks ago for the quebec accord club.

False. The B18A did come in the JDM 3gen Accord. and the B20 who came into the 3gen accord is the B20A. Not to be confused with the 88-91 Prelude.


Firs there is the series number: B

True


now we have the JDM 3gen engine . the B20b
signifiying that it is a 2.0 liter. that is why almost every part will exchange from the USDM B20b prelude engine.

False about the parts from the USDM B20A prelude. Almost EVERY parts WON'T exange from the USDM B20A.


also in the picture to point out differences. the B20b uses the same exaust and intake manifold as the A20a3

50% false, 50% true. B20A uses a different intake manifold as the A20Ax but the A20Ax intake manifold can be used on the B20A. For the Exaust manifold, they are different and the A20Ax won't fit the B20A


Im not flamin anyone, and if i am wrong without a doubt i will apologize. It is just that i want my fellow 3g's to have a better understanding of our cars.

we will all wait your apologize :rofl:

btw, the B20B is the same as the B20Z and they both came from the Honda CRV

That is not a B18A1.... im sorry, clean the block plate to find its a d16 DOHC non vtec that came in the USDM 1989 Integra. how do i know this ypu ask? because of the timing cover. the B18A1 and B18B1 top timing cover is made cast out of the valve cover. not a bolt in plastic guard. Im not flaming just you need to payattention yourself before you htink about "schooling us"

I know it's not a B18A1, it's a B18A ... There is only 1 type of B18A engine and it came in the 3G accord. the US 2g integra had the B18A1 and not the B18A. the JDM 2g integra had the ZC and the B16A...

The D16A1 may look the same because it was build in the same years but it's totally different.

THIS is a D16A1 from a 1g 86-87 integra.
http://www.muller.net/sonny/crx/d16a1/top.jpg

Notice how the valve covers do not bolt in the same places.....

Just check the stats for the JDM 86-89 Accord EXL-S in the modeldata:

Anything needs to be cleared out?



oh i forgot, some of the DOHC ZC/D16A1 engines came with a carb.... but they didn't come with dual carbs like the B18A

01-31-2006, 06:25 PM
Would any of those DOHC transmissions fit on the JDM B20A? I.e. the 1.8L and what would be the code for the 1.8L 5 seed transmissions? http://www.clubaccordquebec.com/temp/l3g10n/3rdgen.html
I would believe that the SOHC JDM, USDM, EDM are totally different. Sorry about going way off topick

If only I had a couple bucks to spare. There is a B18A here in montreal at an engine importer. If it was manual, I would already have bought it for the tranny hehe. No way i'm spending 500 bucks on an Auto B18A tough.

i had a white 1987 vigor b18a. i got my b20a 5 speed out of. i had no idea about honda engines then i was so lucky they just bolted... lol never drove it cause the engine spun a big end and ran noiseyseily and was gunna die ne second.

a guy at our dumpyard has one,..he was sciteing one day sayin he cud do 130KM/H but he ran out of road...umm we thought thats a bit slow...maybe he cant drive?!?!?! lol 137HP tho it shd b able to pull damn fast

Forgive me for my lack of knowledge...but is it correct to assume that if a B18A swap WAS done on a carb'd accord...that a bolt on B-series turbo intake would be possible?

shepherd79
03-08-2007, 07:31 AM
yes turbo manifold should bolt up, but lets not forget that it still has carbs attached to it.

carotman
03-08-2007, 08:12 AM
The intake ports are totally different.

Venyix
03-08-2007, 10:27 AM
The intake ports are totally different.

So the intake ports on the turbo manifold would not bolt onto the b18 then?

carotman
03-08-2007, 11:03 AM
AFAIK, nothing matches the B18A intake ports.

IF you can get your hands on a B18A, just install a B20A head on it. That one matches the USDM A20A ports and you can easily install any later B series intake manifold.

However, you don't need a specific intake manifold for a turbo, it's an exhaust manifold.

It's not an integra engine. It's an accord engine and you wont find it on any junkyard in the US.

Well guys, here's some update.

I was browsing www.preludepower.com (nice guys there) and came across this picture.

http://i59.photobucket.com/albums/g303/DonDominican/100_2339.jpg

This is a picture of a B20A3 head intake ports... notice the port shape and bolt pattern.

I guess the diagram I posted earlier for the B20A3 wasn't accurate. The B18A and B20A3 intake ports seem to be exactly the same.

It would be really sweet if someone that has access to both engines could compare things.

Whats the power specs on B18 carbed? i'm looking for some potential carb upgrades for my ET want to try to get around 130-140bhp from the stock type manifold and twin carbs if the jetting on B18 is bit richer will make it a lot easier to reach. Trying to squeeze the most i can out of this ET with it looking totally stock from the outside. So looking at a 2.0l block, Big valves, ported flowed head, header, exhaust, very mild camshaft maybe, CR ratio of around 10.5:1, and adjustable pulley. Never tried modding an engine with stock carbs to any great length so should be a learning curve!! Hate the stock carbs but at least English ones don't have all those daft emission things on them so are a lot simpler.

Is #26 on the first B18A carb diagram a TPS ?just to add,the lude with the dual carbs also has a TPS sensor like this. so it might be a good idea to look at the carb control systems on it to compare to this one. i would bet there are a lot of things the same. it also has a check engine light and stores trouble codes like a FI system.

Pretty much nearly running 130bhp with my stock ET engine fuel pump is lacking though keeps loosing power at high speed and full throttle i think if i drop my Facet race pump in with my King filter adjustable regulator i might be able to add a few more and at least make the power constant instead or intermitently on and off which is damn annoying!!

Sorry kinda an old thread but....I'm wondering if the dizzy from that b18a can fit on the b20z or b20b? The question is due to the thought of running DCOE's or Mukini's on the CR-V b20...:) Then I could save myself some time by avoiding ECU's, injectors, MAP sensors, etc. and all the trouble thats becomming of FI cars. Thanks in advance!

Thanks for the reply my friend! Now when you say "little mods" are they actually little mods or do I have to break out the chainsaw? I really want to carb a b-series....man that would be sweet:) I saw someone DCOE'ed the h22 in a mag awhile back for the SCAA or Auto-X, they got rid of the EFI stuff to save weight! Hope I'm not wasting my time with this...input is quite welcome!

A18A Got any more pics of those carbs? Can you do us a favour and measure the width of the bores on the inside just in front of the butterfly? Interested to know if they are same as the other carbs on 2nd and 3rd gen preludes. Thanks.

Hmmm Carbs on Vtec engine hey i like this guy go for it i say not sure if you'll have to disable the vtec system though to make it work properly may be interesting to try and setup. Also if your B20Z is making some serious power you may want to think about some carb mods to help make them flow better and or upgrade to bigger ones e.g. DCOE 48/50's but trouble is with that is they bore spacing is wider so you won't have straight shot at the inlet ports. Other options are Racing Bike carbs which are fully adjustable albeit they have to be taken off each time cause the jets are allways underneath for some stupid reason!! But you can get these in 40-55mm and there really small and light.

Yes, you can see the D16A1 distrubutor on that engine. If you want to install it on a later Non-Vtec B series, all you need is the cam endcap from a B20A5 and bolt it to yout B20Z. The distributor will them bolt to the head with 2 ears and will be solid enough.

that mugen intake manifold looks like an ordinary gold top b20a manifold. BUT it has two vacuum line things in the middle of it instead of one.

so if i got a d16a1 (ZC over here) dizzy and crank sensor it will fit to my b20a, somehow i wire it up it will mean the ecu will now not control the ignition and therefore it wont have a revlimiter since the b20a has a ignition cut??

is rwd. again the pod intake and exhaust manifold/headers and is dry sumped.
can see the oil pump on the lower/rear side of the motor.

there should be a good b20a powered parts car somewhere in malasia for you that would be the best thing you would do, swap everything over, the wiring loom fuel tank fuel lines head distributor and intake manifold, either that or jsut swap the b20 in there.

i dont have any idea left than to pick up b20a parts
but with all those parts needed to be replaced, i think it's better to put in a
h22a engine, which came from 93 preludes.
i bet the total price for those parts is about 1/3 from the prelude halfcut
it least h22a is vtec powered
so, need to wait a bit more to afford that h22a
but i cant find any mounting bracket for 3geez in here
so hard to find 1

i wonder, my b18a engine is running weak last few weeks
it's like that my 1st gear will take about 5-7sec to reach 6000rpm
so very2 slow
even my civic 1.6 SOHC will do much better
really dont have any clue what's the problem
guess need to overhaul the engine first

the h22 is fuel injected so you still are going to convert to EFI by swapping the tank and lines and loom etc, h22 in a 3g well i have only seen one and they require lots of modification i hear. but if you had a b20a head and intake you can slap that right on plug it in and away she goes

but i still need to replace all those things even if i want to plug in the b20+injection, right?

What about swapping on a b20a head and a20a carb manifold if you want to stay carbed :P

indeeeeeed but he wants power and an a20a carb wont do that unless he does a weber conversion and some other mods

surely some quad carbs would be easier to attatch to a a20/b20 head than they would be to a b18a head? the spacing between intake ports look quite gay on the b18a

i see
just like u've said, a little bit noises from the engine
plus sometimes the idling turn out to be so low, making my car shaking everywhere(suspecting twin carb prob,
this is why i want to change it into injection in the 1st place)
ah, 1 more thing is the noise that came from the carburator(also?)
it's like "ktang ktang ktang" just like when u put a screw into the inlet(but nothing found)
i think got something loose from the air inlet part bcoz when i hold the carburator, it's stop making noise(nvm can be solved when i have a time)
i'm the only 1(that i notice) in my local area that using this ca2
my friends(who r using later model of accord n civics) keep telling me to put in the h22a or b16a
yeah easy for them to say (-_-")
overall, ok but need to replace the lower arm
it give me a bad sound since 4-5 days ago
dunno if i can find it in here, hope so

I just noticed that the B18A intake manifold gasket is similar as the B20A3 but upside down

I found better pictures of the B18A Intake manifold on Yahoo Auctions. Obviously, the seller didn't know what he had and labelled it "B20A".

This is clearly a B18A manifold.

Notice the square ports and stud spacing. This is really the same thing as a B20A3
