I know this is in the wrong section but I need help quick on this
thank u

[guaynabo89]

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

[HondaSi88]

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!

[Don87LX]

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.

[HondaSi88]

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

[guaynabo89]

you might be able to use the regulator.

[HondaSi88]

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

[toastyghost]

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.

[AccordChemist]

where did you order a jdm b20 accord engine from?!!?!

[HondaSi88]

i actually got the info from the AF board one87jtstyle posted
here is the post and the number i called



Here's the email, [email protected]
and here's the number and info, I haven't ordered it yet, and it's in Ca, so I don't know how much shipping will cost. Yasuhiro (Yasu) Eto

The guy was really cool its came out to 650.00 but the shipping is gonna kill me
he is gonna call me tomorrow for the shipping total

[HondaSi88]

im trying to do some b20 search right now but i can't really find anything.....

[1988starter]

Si how much for the cam I want it.

[MoonScryer]

$650....hmmmm....

[88LXi68]

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

[carotman]

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]

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]

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

[YK86]

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.

[YK86]

Here's a pic of the ignitor.

[HondaSi88]

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.....

[carotman]

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.
