I found the solution to the B20A "RARE" transmission.

[Ichiban]

what i have found is:

86 only had the 21200-PC8-J00
87 had both the 21200-PC8-J00 & J52
88-89 Had only the 21200-PC8-J52

What is the defferance between the two tranny's?

This would be good to know. My tranny came out of an 87 twin carb lude, but since it has the larger 3g sized splines, it's either been swapped, or is some sort of factory botch job.

Also, Aaron, you want to sell me a B18a bellhousing without speedholes and JB weld all over it?

If I'm not mistaken, the 87 lude's came with either the A18 or A20, and I'm pretty sure the 87 Si Lude was the one with the dual carbs and was an A20. Long story short, same splines.

I have one in my garage and I'll check it out in the next few days and come back with that code too.

lol i told you that gearbox had many holes, but im sure you will fix it up

It's almost completely fucked out. Turns out JB weld actually has a greater hardness than the aluminum, making it pretty much impossible to grind out. Also, there are 3 or 4 trashed bolt holes, and the bore for the oil seal is, well, mostly missing. Oh and the 3 big holes.

I can put a bunch of time into restoring this bellhousing, but all the welding may distort it to the point that it kills bearings all the time or just won't seal. I'm kind of hoping to get another one in decent shape if at all possible.

Maybe you can use that stuff:

Seems less prone to distorsion.

It's already welded. Doesn't seem to have warped more than a few thou, and the gasket will make up for that. Gonna plane the engine side flat on the mill, just to avoid any undue stress.

getting hard to find the old b18 accord as all the b18 motors have all blown up and been scrapped now. there was one on trademe but do you wanna pay 400US for it? lol

400us for the tranny? I would be willing. this motor is no good without a tranny, unless i make an adapter plate.

yes i did.

[AccordB20A]

lol i was looking on trademe and i cant seem to find the car thats b18 manual anymore.

this auto hooked up to mine (b20a) is still being loads of fun, and is much more power than before even with the mods on my A20. This thing will tote the mail and drag the dog... lol

well i've got the auto trany that it came with. but i'm not about to convert my car to auto just to solve my trany issue. i'f your looking for an extra one let me know

[Ichiban]

Some info on this: The JDM B18A bellhousing has a pressed in roller bearing that differs slightly from the USDM A-series tranny.

JDM bearing- NSK 8E-NK 33x55x21

USDM bearing- NSK 8E-NK 33x55x19

Because I destroyed the JDM bearing whilst removing it, I machined a 3mm spacer to fit behind the other one, in order to locate it properly within it's bore.

[hammer3rd]

Has any one actually done this,jdm b18a bellhousing with a usdm a20a tranny on a jdm b20a motor. If so I would like to know how it worked out as I want a 5 speed to go with my swap.

[AccordB20A]

^^ posted last year and no one helpted him out. i had a 2nd gen prelude casing and internals bolted to the bellhousing i sold mike, it drove good as i just neded to keep topping up the oil cause it dripped out haha

i have another one of these bellhousings if anyone is interested, gearbox is still in one piece

[Slipup]

How much do you want for the bellhousing? Send me a PM if possible.

[AccordB20A]

i cant sell it atm as its my only gearbox :(

[Slipup]

Crap lol. Well I have a buddy in Okinawa but he said he isen't in the mainland so its harder to get stuff. I just hit him up to see if could get me a few things anyhow. What model/years car did this engine come in so I can give him a better idea when he goes looking.

[AccordB20A]

85 to 89 accord ca2 for the correct bellhousing, but if you want a complete gearbox BA1 prelude or CA3 accord will work.

[Slipup]

Thanks.

This makes me wish i never sold my 86 hatch LX-i

[fmn716]

I am only confused about 1 thing, will the B18A Gearbox work with the half shaft ?
