If I remember corectly There was hardly anything that was the same.

When I was looking into that engine I never got one because I had spent to much money on my a20. I was talking to Mike and he told me I couldn't use my pistons, rods, flywheel, and all this other trick stuff that I had from the a20.

just my 2 cents:)

thanks for the info........I almost bought some pistons and other engine goodies for the a20. But as for now I only have the cam, headers, coldair intake and msd setup......Im gonna sale the cam
and the headers and basicly bolt everything else on to the new engine!

I doubt your headers will work. your intake maybe. your USDM motor is an A series and you are buying a B series motor. different series=different parts.

im selling all that stuff!
headers, intake fuel reg and whatever else is on this car

i thought too......so how hard is it to add an vtec head to the b20?

Where did you order your swap stuff from and how much did it cost total? I've been checking around about B20A swaps and am trying to get the lowest price. Any information you could give me about whoever you're getting your stuff from would be great.

For the JDM B20 ****I think*** you can use parts from the USDM B20 i.e. header, cams, cam gears.

carotman
05-04-2002, 07:22 AM
The header is similar between the US and JDM B20A.

The clutch is the same but the T/O bearing is different.

The camgears are much bigger on the JDM.

The rest will have to be verified... maybe the pistons are similar.... but that's about it.

HondaSi88

ok what about axles, ecu and basic parts
? thanks for the info!!!!

carotman
05-04-2002, 10:54 AM
The axles are the same as the A20A Accord.

The B20A uses an intermediate shaft but you can use the USDM axles.

The ECU is different from the USDM Accord and Prelude but someguy is supposed to have used a Prelude ECU with his B20A.


I'm not that familiar with that engine. The oil filter is the same amongst all Hondas.. so no worried here.

The oil pan might be the same..

I will do ALOT of research on that (I got the JDM parts Catalog) and I will compare between the Prelude and the A20A...

We might be able to sort a list of compatible parts

That sounds like the best Idea I ever had....

AccordChemist
05-04-2002, 01:47 PM
ok lets clear some things up.. are we all talking about a jdm b20 accord engine or a b20a? and hondasi88 does the $650 include transmission and everything you need to swap? since the b20 is a direct swap, all you really need is the engine and tranny? or is there more like ecu, etc.? and what if your car is auto could you still swap it?

carotman

Well I checked everything regarding to the engine and the following are EXACT MATCH for the parts number

Rings
13011-PK1-003
13011-PK1-004
13021-PK1-003
13021-PK1-004
13031-PK1-003
13031-PK1-004

Pistons
13103-PK2-000
13105-PK2-000

Rods
13210-PK2-000

Clutch
22200-PK1-000
The pressure plate is supposed to be interchangeable too but aren't the same part number

JDM
22300-PH3-J00

USDM
22300-PK2-000

That's all that matched my research..

If you get in trouble with the rings/ pistons... they will work OK

The crank almost matches
JDM:
13310-PH3-010

USDM:
13310-PH3-020

So I can't confirm it's compatible but it's close

Oh an the ECU will not match but that doesn't mean that the prelude ECU will not be able to make the Accord engine run.

Here are the ECU numbers for the JDM B20A

83305-SE3-010ZD
83305-SE3-010ZB
83305-SE3-010ZE
83305-SE3-010ZG

I also added this to the FAQ

I can help a bit. I was very close to buying Mike Lee's but bought something else instead. The headers from a USDM B20 will fit BUT you will need to get it chopped and rewelded at a different angle since the USDM tilts back while the JDM doesn't. There's always a guy on E-bay selling DC and Pacesetter headers for Preludes. You can use most of the USDM engine rebuild kit if you are going to get new gaskets and stuff. You can also get pistons from www.raceeng.com to raise the compression (they quoted me $370 for 11:1). You can also upgrade the rods with ones meant for the h23 if you want. You will also need to do a bunch of work to the ignition system. If you are lucky, you'll have the external ignitor which is usually clipped onto the EGR valve in the intake manifold. The USDM ignitor is a 4 wire while the JDM is a 3 wire (maybe you can rig something up). I don't know how compatible an ignitor has to be but the 5th gen Accords also use a 3 wire from the looks of things. Also, hopefully they gave you the B20 with the simular intake manifold. Like over here, the JDM B20 is supposed to have two different types (when it comes to vaccum connections and stuff) like how ours are different between the 86/87 and 88/89.

Here's a pic of the ignitor.

Carot and YK thanks for your help I need to get yall email addresses so i can ask all the question that I need!
And as for the price I called the guy on friday he out in CA somewhere......anyway I told him like 20 times I want the jdm b20 from and 86-89 ACCORD and told me 650.00 with the 5speed tranny!
Monday he is gonna tell me the shipping so i can't wait!
I would get the b16a but I don't want to pay for the mounts.....

May I add this to the FAQ Yasu,

Whit your permission of course :p

YK86

I have a bunch of info too like the piston pin sizing and stuff but I'll have to dig those up. I do know that with custom machining to the rods, you can get the B series pistons in there too which would be great since there's so much pistons and rings on E-bay you can get for fairly cheap. There is one guy in Japan I was able to keep in touch who helps run the Aerodeck site and if I can get a hold of him again, I can get some more info. It seems like getting a factory service manual for these engines is EXTREMLY hard but it would be nice if someone could get one.

Darry took a trip down to one of our engine suppliers the other day and he sed that they have 3 JDM B20s in stock and they where willing to sell them cheap cuz nobody wants them. I think that when they bought these engines they miss took these engines for the prelude B20s and bought the accord B20s. From wut darryl told me was that there where 3 long block B20s, 2 with transmissions and one with out a tranny. No axles, no wiring harness, and no ecus. I will post more about this in the swap section after i talk to darryl more about it.

Justanothermike, please do post some info about those motors you found when you can. Everytime I mention a JDM B20a for the 3rd gen Accord to someone around here, no one knows what I'm talking about.

HondaSi88
05-04-2002, 08:22 PM
might be the same place that i called!

CARBurn
05-04-2002, 08:27 PM
Yeah, the only thing that people think of when I mention a "B20" is the Cr-V or the old preludes!

carotman
05-05-2002, 05:21 AM
Bah I'll get a complete front cut from Europe I think (I may bet one for like 1000 canadian plus tax and custom fees)


The problem with the B20A is the Knnowledge base in America and the parts availability.

I would not be ready to buy that engine for more than 300 bucks including the transmission. Those engine importers are stuck with them forever.

Like I posted, there are 5 different ECU types.. It all depends what type of idle control you have, and the type of intake manifold (different for between the years)

It also depends on your distributor and other things like that. So, unless you get the engine WITH the matching ECU, you're on your own... and in trouble.

HondaSi88
05-05-2002, 05:45 AM
carot do u know of any dealers or junk yards that let those engines go for that price? email me [email protected]

Another problem that im having is the shipping from CA to MD
They haven't got back with me yet and that is really bothering me!!
So now im calling everyone about the b20a and b16a

carotman
05-05-2002, 06:25 AM
I don't know any junkyard that will sell them fot that price.

I found a place in Montreal where they had the 1st gen B20A (86-89). It uses the same idle control and Intake manifold style as the 86-87 A20A3/4

They were asking 800 and I had them drop to 650 US. The guy wanted an account before I would get it delivered.. I never agreed to the account (he told me that would make sure no one would buy the engine before me) I never got it delivered becuase I changed my mind.

I checked this spring and the guy still has the engine.. He's been having it for 3 or 4 years I think. He will NEVER get rid of it.. Maybe in 10 years or so...

Like I said, the problem is the parts availability and the ECU.

A guy told me it would cost around 500 Canadian to ship a whole front cut from Belgium... I might go to that route. I can buy the front cut for 300 CAnadian and get it shipped. For 1000 or 1100 canadian, I would get a complete fron cut with EVERYTHING needed to install that thing in my car.

That's roughly 700 US. Plus, I would get the CA front end that I'm sure some of you guys will want.

You just have to deal with the guys there and make them realise that they are stuck with those engines forever.

The guy at the engine importer told me: "Yeah but YOU want it, so someone else might want it...)

Bullshit... there are so much variations in those engines....

If you get a B20A, make sure it has the dual stage intake manifold, it will ease the instalation alot...

Any other questions?

DarknessRS
05-05-2002, 05:01 PM
what does a dual stage intake look like and what year is it found on?

HondaSi88
05-05-2002, 07:42 PM
ok here is where i stand........Im not gonna post the whole converstation with the place that im getting the engine from but here is the basics..........Carot u are right on the fact that NO ONE wants the b20a so he wants to get rid of it.......but they still don't know the shipping till monday!
I found another place not even 30minutes from me with an
b16a for 1100 everything 5speed , but whats up with the wires being cut at the firewall......

carotman
05-05-2002, 07:58 PM
ok it all depends of the price... the complete B series kit from placeracing costs around 1200 to 1500 (not sure or the exact price)

This is a serious turndown!!!! The wires being cut at the firewall isn't a problem as long as you have the complete enginebay harness, the rest, placeracing can take care of it..

The B20A is good cause nobody wants it... thus you'll get a good price on it. It's just a little harder to get it to work... but I'm sure we can all help you :)

MoonScryer
05-06-2002, 04:34 AM
$1937 when I added up the whole kit, for everything, last time. Did they drop their prices?

B20 would be nice...the power would be so nice in our cars...but the B16 would be a bit more fixable, given parts from the A2/3 fit on it.

Thoughts....

CARBurn
05-06-2002, 05:10 AM
Carotman, does the place your talking about to get a complete front end cut have a website address?

So a front cut engine would be better than to just get the motor and tranny cuz you get everything needed to start and run the car, cool.

carotman
05-06-2002, 05:55 AM
nah they don't have an adress. It's someone I got contact with in Belgium that might be able to do it for me...

the jdm b20 is a really difficult engine to install you need special motormounts due to the engine sits far back towards the firewall but the accord b20 sits foward and the monts should match mor or less

carotman
05-06-2002, 12:38 PM
the JDM B20A only erquire that you use the rear tranny mount from the JDM engine..

no mounts are required...
