Nice.

OK, what ECU did you use? Oh, and this guy who had them; did you say he had an automatic? Just wondering....

how does it run? and will u guys sale these in the future?
is it still a manual and what tranny did u use?
and whatever other info u wanna share!

Is it me or you used the A20A distributor to make it run???

Damn that looks nice in that engine bay! You got a 5 speed on that mofo right? I need one of those motors, do a dyno run and get us some track times!!!

What's with the vacuum advance on the distributor? Is that the distributor that came with the engine or did you use one from another car? JDM Accord B20A's came only with electronic ignition(no vacuum advance). Unless, your B20A is from a 2nd gen Prelude, which did have vacuum advance.

carotman
06-17-2002, 07:13 PM
well maybe he used the distrubutor from the Prelude and therefore he was able to keep the A20A ECU.......

im still debating whether to save for a b16a swap or a b20a swap,

the b20a looks tempting because it'd be cheaper, and has more torque and low end power.


but the b16 looks tempting because its got VTEC and the aftermarket support for it is sweet!

ahh! However though, depending who you talk to around here the price of a b20a + transmission is roughly $1600, which isn't bad, considering it'll bolt in while the b16a would cost more, but still require more capital to be spent to get it to sit in.

hmmm

Import....look at buying from a country where the USD has strong buying power.

I found a b20a here + transmission for $1500 , so that'd be about $750 + shipping and handling.

look around japanese importer and shit...

How do I get in touch with these people? I have tried "import parts" places and they are for foreign-brand USDM vehicles mostly. Those that actually IMPORT their imported parts either don't know what I'm talking about at all, or think I'm talking about a Prelude or CR-V motor, or know what the engine I want is and can't get it. I don't know what to do about this except keep looking, which hasn't been working out too well. Could you give me the web link or email of someone in Australia that would ship what I want overseas for $700 (USD) + S/H? :)

just not sure the condition

06-20-2002, 12:41 PM
is that out of a prelude? if so what year? what motor mounts did you use? also what axles? help. i'm thinking more on this than on the b16. which would be faster?

06-20-2002, 03:06 PM
Its the JDM Accord motor...well, the Accord 2.0SI. It makes 160hp on Japanese gas, but we have yet to see what one can do here in the states.

Here's the quick rundown of why the B20A rapes the B16A in the poop-chute (er.. manifold? how does a fucking car poop anyway?): first of all Jap gas is higher octane than US gas, which makes no sense to me since they also have more rigorous emissions standards. (Please note my ability to miraculously use "sense" and "since" correctly in the same sentence. Yay me.) More octane going in equals more oxide coming out, right? Anyway, assuming you could get the approximate performance out of the B20A here that you could in Japan, then it's far superior to the B16A. They have the same horsepower but the B16A has about 30 ft-lbs less torque. I believe the exact numbers are 140 and 111... Anyway, I'm not sure why the B20A has so much better torque conversion but it's probably got something to do with the fact that the Accord is a heavier car than the Civic or CRX for which the B16A was originally designed. You need more torque to move a bigger car. Couple the greater torque with the ease/cost advantage of the B20A swap into our cars... ladies and gentleman, I think we have a winner. IF you can find one that is.. which seems to be a problem as I'm finding out. :( Now if you're planning on dropping not only a couple grand on the swap but also an additional couple grand on mods, the B16A might be more worthwhile simply because you can get pretty simple bolt-on shit because the aftermarket support is great, whereas the B20A will need a lot of custom-fab or imported shit. And they're still making B16A's in a form compatible to the old ones (the Civic Si and DOHC Del Sol are two recent examples), while the B20A in it's 3G form at least is more or less extinct. I also just noticed this post has a couple of anyways, which means I'm going on unrelated tangents. Oh well, it's late and I'm a fuckup, you'll deal..

Just to let you guys know, I saw the Open-loop crew at Sacramento Raceway yesterday and the B20 Hatch hit 15.7. Gordon is looking for better though, as that was only his second run with the new engine. 4th gen Accord ran 14.7 with some traction problems, thats what 2.2 liters of pure Honda torque will do though.

I hope that b20a was with stock cams and stock exhaust manifold because he was getting 15.7 with his A20.

Basically if the engine came with that distributor than that particular engine came from the 2nd gen Prelude which was available with the B20A. All 2nd gen Preludes with B20A's I have seen have the vacuum advance distributor. Check out the pic of the Prelude I have attached. Anyways, whether vacuum advance or fully electronic it's still a B20A...160hp!!

Go to search engines, and just do a search of

Australian jap engine importers

try different combinations, thats how I do searches. IM actually wanting to go up to melbourne eventually and go to the wreckers and that there that specialise in Jap parts, Honda's ,etc. Im wanting to one day do a b20a, over a b16, merely out of cost reasons. THe b16a is a nice engine, but the amount of hassle, aftermarket parts and the lack of experiences people locally to deal with it makes it very costly. Custom mounts, wiring, axles, will cost me just too much, way more than i want to spend. I'd rather spend about $1500 for a B20a with all the necessary parts, and just drop it in. Versus all the other hassles

carotman
06-28-2002, 05:21 AM
Then I just basicaly need an engine that has the same Idle control as my A20A 88-89 and get the vacuum distributor.

I will then be able to use the stock ECU to make it work...

Simple as 1-2-3

CARBurn
06-28-2002, 12:44 PM
Sounds like you've got a plan...

gr3k0sLaV
06-28-2002, 12:51 PM
I wish someone would create a detailed guide on engine swaps, in the b20a case there is obviously more than just having the engine, the mounts and the ecu.....

what about the wiring, sensors, vacuum lines, etc? it cant be as easy as dropping it in and turning the key.

What sensors and things in the stock accord will work with a b20 and so forth...

carotman
06-28-2002, 03:36 PM
Yeah I got something in mind......

I noticed that the B20A has the same sensors and idle stuff as the A20A (if you take the same years)

The only difference is the distributor that's controled electronicaly instead of a vacuum.

So, if you take a vacuum distributor, you will get the B20A to run with your stock ECU.

The only problem might be that you won't get the 160 HP because of the fuel maps and stuff like that.

A modded ECU will take care of that.

Or just piggyback stuff.

CARBurn
06-29-2002, 06:22 PM
ah, so there is hope in getting those engines to run at least. So you have to modify the stock ECU or how about a stand alone one to achieve its peak power? I do know the stand alone ones can be expensive but it might be worth it, I dunno.

You must be the guy who had the B20 hatch. You bought Mike Lee's Ludespeed turbo kit right? How is the install coming along? Oh, I actually e-mailed you a while back asking how you hooked up the ignition for the b20 when i was thinking about buying Mike's but you said it was complicated and didn't go into details just like Openloop is sort of doing right now. If you can post that kind of info now, or write up a basic how to or something, that would be greatly appreciated by all of us. The ignition and finding higher compression pistons (since Mike's had the 8.5:1) was the only thing that stopped me from buying it.

07-01-2002, 03:19 PM
I see that the B20a is a CIA top secret project so I don't think Im gonna bother trying to get any info on this!
All I want is a site or place that might sale these engines!
Nothing more nothing LESS!!!! Every place that I contacted said that the b20a was a forgot about motor! and its basicly cheap between 600.00 to 800.00 for everything.....
thanks

I'm not entirely sure, but I get the impression that mike is not a owner of openloop. I think 2 other guys are. Mike likely broke the news of the swap without fuguring that he'd be asked questions that the owners of the business would not want shaired. Which would explain why he's been mostly silent on the topic. So I don't think he's being cocky, I think he's been put into a very tuff circumstance where he has all the details, but the owners have tied his hands. The owners may think that you should come to their shop and pay for such a swap, and if they give you all the answers, you won't show up. Of course it's possible that none of what I said may be right and he may post something where he laughs at me. But this is the kind of thinking that happens with out real info. Just my 2 cents, no offence to ANYONE.:smokin:

B20Aturbo I wasn't bitching about your post... more about Mike's acting like an engine swap was a fuckin Enduring Freedom black-op or something. But if what Jim said is the case, Mike's unwillingness to respond on his own thread is understandable.
BTW how much you want for the B20A/B2K5? Approximately how much will shipping run to send it to Harrisonburg VA 22802?

First of all, I wasn't trying to bad mouth you, I was just stating what everyone else who has posted on this topic was wondering, why all the secrets, and what do you have to offer, point blank. Now you say you have done this swap before, it would be nice if you could offer some help to some of us that are thinking of doing the same thing. I thought this forum was to help other people doing upgrades and maintenance on their vehicles, so if you offer to help fine, if you don't want to help then say so.
I am trying to learn as much about this swap as possible and if I have to go off on my own and do this because some people want to keep it to them selves, I'll have no problem doing it, I learn things as I do it anyway. But I'll be sure to post a nice how to on doing the swap, so others can at least be able to do the same swap if they wanted to.

And to Openloop, I completely understand you not wanting to unveil your secrets cuz then you would be out of business. But it would have been nice if you put some sort of disclaimer under the pics to lets us all know you would be able to divulge certain information about the swap.

B20ATurbo, when i spoke to you awhile back you were the same way you didnt want to share info which is understandable since you did do a lot of homework. It seems you have come around to help others but the B20A is not as hidden as before now their is and handfull of running ones out there. The only problem i have with the B20A is lack of OEM parts available which is what drew me away from it before. I will be doing a swap and i wont rule out a B20 yet but im leaning towards a different swap such as a B18 GSR because of parts and research on the other b-series. Im glad you kept your car and didnt sell it hope to see it soon.

When I e-mailed a bunch of known people with the B20 that was working, AccordEXI was the only guy who really took the time to help me out. You said it was too much details when it comes to the ignition and I left it at that. I have nothing against you and I understand why you would reply like that too because I also got a ton of e-mails before the how to went up on the board on how to do a 5 speed swap and I spent 20 minutes or so typing up all the details and most people didn't even say thank you which can be very discouraging. Anyways, none of us are saying "gimme gimme gimme". If you can help out great, if not, that's fine to (everyone has reasons). You offered help on your first post because no one else was sharing and we would love to hear anything you have to offer.

Jim was correct on his earlier assumption. Gordon(the owner of the Hatch) didn't even know i posted the swap pictures on the board and then it started getting out of hand with Mr B20aTurbo shooting off with out knowing anything. The fact is that this is not even my car and i deffinately have now right to even talk about it on this board. I had gordon take a look at the thread and he was cool about letting the some of the basics of this CIA operation out.
After all like he stated we're here to help everyone as much as possible and all that other stuff.

Wut you need to do the swap: Integra left axle(i think it was the second gen one) to go with the intermediate shaft( we don't recommend trying to use the accord axle because obviously the B20 was ment to run with a intermidiate shaft, using the accord axle with cuase torque steer), Integra(1st gen) distributor if u wanna run the stock ecu, custom rear mounthttp://openloopmotorsports.com/mount.jpg, and a modified Lxi A pipe(down pipe). Running the LXi pipe with not be the best thing either as the two pipes from the B20 A pipe are actually biger then the Lxi pipes. We made a DC header from a 88-89 prelude fit the. basically u gotta cut out a section of it and then weld it back together.

http://openloopmotorsports.com/header1.jpg
http://openloopmotorsports.com/header2.jpg

back to the politics for a minute, of course there are gonna be somethings thati will not be able to share with you guys, but of course i try to be as open as possible. I had one other guy on some message board ask to come take a look at our H22 accord so he could show someone else that would do the swap for him. In my mind i was like "F**K the hell off" After all when u don't have business you can pay the bills and thats not cool. Our project cars are examples of our work, which would show our customers what we are capable of and that is what we want to do with our cars. Happy swapping!:)

Ok here's my example. here in australia i'd be hard pressed this f far south to find anyone within my state who would know much about a b20a swap and the fact that there are practically no done up or modded 3rd gens around here, makes it hard for me to get info or find someone to do the swap...leaving it up to me to get it done myself and get the information in order to get someone to do it for me or help me with it.

So i'd take whatever I could, funny how the FAQS just say you need the ECU, motor mount and motor...but now I read u need another axle, custom mounts and all this stuf..

I wish someone could just give some clear and correct answers.

From the faq it makes it sound like it's all bolt on, and no mention of integra axles, or distributor.

mike is correct about the dist you must use this dist you run the stock harness and the stock ecu...as for the intermediate shaft that is correct too and you can use the integ axels but the stock accord axelss you can use as well they work fine i have them in my car now...as for custom mounts the only reason to use custom mounts is for the rear tranny mount which the 3rd gen rear tranny mount doesnt work so that is why maybe they had to use a custom mount...the only way around this is to get the JDM rear mount that way everything bolts up.....the motor bollts right up you can use your stock harness,stock ecu , and stock axels just make sure you get that intermediate shaft....you will find alot of parts will work on this motor from your a20a...as for the dc header that is correct as well i had to cut the flange off where it meets with the downpipe and redo the piping to go under the ooil pan the prelude header hits the oil pan its not to hard to do any any muffler shop can do it for cheap. The big problem i see with doing this swap was the spark getting spark for the motor was a big prob that people were having but the best thing you can do is try to switch the JDM parts to USDM that way replacement will be easy example the integ distrib. I also installed AEM cam gears....when looking for parts i learned to to tell the honda dealer or parts stores that its a JDM motor becuase right away there like oh umm we dont have anything for that but thats un true because alot of parts work with this motor its more like honda took an a20a motor a b20 prelude motor and a b18 and put them alll together to make the motor thats the basis that i can give on this the parts are out there it just takes a little research

Thankyou, what exactly is an intermediate shaft? ive never heard of it before.....

Also what happens with all your sensors, vacuum lines and all that? the vacum control box and everything? does it go or stay?

b20aTURBO
07-03-2002, 08:21 AM
the intermediate shaft is behind the motor its where the axels connect to...as for the vacume box that statys all the vaume lines connect to the motor....there are 2 diff yr b20a motors as well just like 86-87 accord motors and 88-89 accord motors diff vacume on each the newer has less vacume on the motor...you can tell the diff by the valve cover the older series is the gold vavle cover that everyone has seen the newer has a black valve cover

our engine supplier has a like 6 B20s or something like that but only 2 with manual tranies. If we can somehow get the trannies we could sell them. I know for sure that gordon wants to keep one more for himself to play with, but the last one i don't think we need. Our options where to sell it as a complete swap with everything needed to do the swap and bolt right in. U know, with the custom mount, axles and distrubutor, or maybe a rig for a different ecu. Its an option we have that i have to discuss with gordon, so i'll get back to you guys.

Also one other thing i wanted to mention about the B20 installation was how good the over all balance of the car was afterwards. The steering with the power steering hoooked up got pretty easy and cornering got much better. no more PLOW! I have good reason to believe that this engine could be a good 100lbs or more lighter then the cast iron A20.


honda took an a20a motor a b20 prelude motor and a b18 and put them alll together

I would say that he B20 prelude, A20, and B18 evolved from the accord B20. Believe it or not but this engine is freaking OLD.

I can definitely understand Yasu's comment about people be ungrateful about the information given to them. I try not to be, If someone helps me out with something I try to do the same in return but at least say thanks for the help.

All I have to say is thanks B20aturbo and Mike for passing along some knowledge on this swap. I know I appreciate it, and it takes a little more of the headache and hassle of trying to swap that motor.

Mike, I'm definitely interested in that spare B20a motor, let me know when you and openloop decide what you are going to do. Again thanks.

B20aturbo you live in NYC? You think I could drop by and see your setup?

I have done the JDM B20A swap as well and one thing I do not see being mentioned is the fact that the front mount is different as well. You can get away with using the A20 front mount but if you want the engine sitting 100% correctly get the JDM mount. Check out he attached pic: 86 BT front mount left, JDM B20A front mount right.

Hey you guys,

I haven't checked this site for a long while. And when I did, It looked (at first) like nothing but haters and bashers..and the sad thing is it was 3gers bashing themselves. But - I'm glad that the dust is settled. 'Cause there's no room for bashing and hating.

Your moderator Yasu had to step in a few times and settle the dust. Didn't look good though that he had to to that.

Good job to Yasu and the other moderators for keeping the site running...anybody know how much shit he reads everyday? He has to put up with my drunkenness too :)

Good job to you all for keeping up the rides, replies, and posts. I take second looks still when I see a 3rd gen on the street.

B20Aturbo, Justanothermike, AccordEXi, Carot, Rob etc - thanks for all the information - what you guys are doing is all good - joining all the info together to get the low down.

That was the problem doing the swap way back then for me...only B20Aturbo and I had the motors - totally guessing game with the swap. Hey - nobody has all the answers - right?

Keep the movement alive (sound slike a commercial)!

I found an 88-89 B20A in montreal (with the correct Idle controls for my stock ECU)

I plan to run it with the stock ECU for now using a vacuum distributor.

My only concern is the manual tranny, the 88-89 B20A I found is automatic, I did manage to find a manual tranny but it's from a goldtop B20A (earlier model)

Would this transmission work on the newer B20A ???

I heard they had different transmissions for that engine

BTW guys, I can get you B20A's (no trannies) for real cheap here

b20aTURBO
07-08-2002, 08:16 PM
you are correct they havea diff tranny for the new b20a ive been looking at the two and experimenting i think the flywheel and the clutch mount up but the gear ratio may be diff for the newer year the tranny you want is the f2k5 i beleive i can check on it if you want i have that tranny here with the newer motor i have 2 b20a with the b2k5 thats the gold top

carotman
07-09-2002, 09:30 AM
Well, if only the gear ratio is different, that doesn't matter too much.

Will they bolt-up to the engine?????

I did get an Open-Loop Motorsports flyer put on my accord though :). Hopefully the person who put it there recognized my 3rd Gen (the one with RACSO on the plate)

I'd liek the information on teh B20A's in Montreal...or at least the shop thats importing them....since every place that I've contacted told me I was full of shit...(luckyStar)...wasn't untill I sent them pictures(thanks to who ever it was that posted those) that they totally back pedaled and said they can't adn won't get any of them....

carotman
08-12-2002, 06:47 AM
there isn'T much info to get on this,

There is 1 shop that has 2 left (they both have auto trannies)

They are sitting outside, in a yard. I don't even know if the guy still has them.

They can be had for relatively cheap but they would need to be shipped (of course)

Anyone knows a cheap way to send those ???

Your car cant fit ANY B-series. It will only take the normal B-series like B16A to B18C etc....They are talking about the JDM Accord B20A similar to the older prelude motors. They uses the accord mounts with the addition of a rear mount. If parts were readily available this would be the ideal swap for the accords and it is realatively cheap too.

Now I'm wondering... an importer about 7 hours from my house said that the JDM b20a would drop right in my 89 Accord, and hook right up with the tranny. I have no idea if he was talking about the gold top or black top or anything at all, but he guaranteed it wouldn't have more than 35k on the motor... pretty cheap too I think.

He said the automatic trannies are different as far as he knows, but the 5-speeds link right up. If he was right, then everything else here wouldn't matter, (axles etc), because as long as you're using the original tranny, all you need is the long block with a few extras...


Does he really have no idea, or is he thinking of the wrong car? He said the motor mounts are all almost the same, and that I could use my tranny without modification...


I've been searching the boards for weeks and can't find information about the 5-speed transmission, how much different it is, if I can use it, and/or what it took to mount the JDM b20a transmission in place of the a20 if it's necessary...

hmm...

b20aTURBO
06-28-2003, 08:03 AM
the 5 speed tranny's will not mount up you need the JDM trannys in order for it to work..if that was the case the guys would use there stock a20a trannys...the trannys are diff along with the rear tranny mount is diff as well...the importer is correct in saying that it will bolt up to your car but you need the mounts and the tranny...ive sold 2 complete b20 motors so far with 5spd my motors come with everything that you need

08-17-2003, 02:49 AM
Hi yes I know many people have done this swap on Accords but I own a 87 Honda Prelude SI and I would like to buy the engine so i can do the swap in my prelude seeing how in Japan the motor also came with the JDM Preludes of the same year i own so I would please like if some 1 can respond to better help me and if so please give me the parts needed to at least make the Engine run and also be installed...i know most people do custom mods but i just want to bring it to stock level first before doing all the mods that why i would need a parts list for each thing i'll need to buy or get from a yunkyard if needed or can also prices for the engine and tranny and what can i use from my old prelude to cut cost thanks.

KnightLuder
08-30-2003, 07:48 AM
robm87PreludeSI, We are in the same boat. I am looking for the motor as well. It is very easy to install the B20A into our cars. The only problem I am running into right now is trying to find the motor for a good price. All you will really need is the engine, tranny, and ecu. Let me know if you find a motor for a good price and maybe we can buy them at the same time to get a better price.

10-27-2003, 09:54 AM
Yeah, that's the frustrating part, there is a lot of "B20A" stuff out there, but not much of it applies to the JDM Accord B20A. I've been poking around a lot, looking for a B20A w/5 speed or just the 5 speed and I'm not having much luck. I try calling or emailing just about any shop I can find that advertises JDM motors. Many don't know what the hell you are talking about and the few that do, don't have any Accord B20A's and no plans to get them.

The frustrating part for me, is there has to be a lot of these things sitting at wreckers in Australia, New Zealand, Europe, etc... but no easy way to get them.

We need a hook-up overseas that can locate these things and help arrange shipping. They could probably make a few buck just doing the leg work to find them. (hint, hint, any overseas guys listening?);)

Gregg86DX
10-27-2003, 12:34 PM
There is a lot of info on the Accord B20A's around here, but quick answers are Yes, Accord B20A only came in cars sold overseas and the easiest way (IMHO) to tell an Accord B20A from a Prelude B20A is the oil fill cap will be next to the distributor on the Accord motor and near the timing cover on the Prelude motor.
