2nd Gen Accord SEI B20A Swap

[SQ is the SQUAD]

off topic

i love it when someone blast a n00b or even a regular member about bringing back an old post. it only means that someone SEARCHED for something

[2ndGenGuy]

Man that is sweet. I would love to do this to my car. I'm just lacking experience, time, and money...

Wow, I can't believe I missed this one.. I always thoght it would work but never had the money, or the b20a, to try it. About those sei spindels. The actual hub that fits into the bearing can be pressed out, you need a good shop press but it can be done. This is the really cheap and hard way to replace a wheel bearing. If the 3g uses the same inner diameter on its wheel bearings then you should be able to put a 3g hub into the 2g carrier no problem. If the 3g hub is to big (odds are that if it doesn't fit its going to be too big) then you should be able to take it to a machine shop and have it turned down. I'm probably going to do this when I break my 2g's axles. Which I bet will happen once I stop running bald tires that I got from a junkyard. Then again it hasn't moved in almost a year because of lack of money and time to do all the minor repairs that have crept up. But thats enough ot ranting from me.

well, do i have a reply for you....
In some other thread i spoke about going to the bearing place and doing some cross-referencing. Well, here's how it goes: (Federal Mogul bearing #'s)

Bearing B-32, (36mm bore, 2.8363'' OD, 34mm inner/outer ring width), fits 81-87 Prelude (exc Si), 81-85 Accord (exc SE-i)

Bearing 513025 (38mm bore, 2.8362'' OD, 34mm inner/outer ring width), fits 85-87 Prelude Si, 84-85 Accord SE-i

Bearing 513053 (40mm bore, 2.9937'' OD, 41mm inner ring width, 38mm outer ring width) fits 86-89 Accord.

As you can see, the 2g and 3g bearings are quite different, but the 2g and Si/SE-i bearings are identical, except the 2mm difference in the bore (ID) that will allow us to run the SE-i/Si drive flanges. changing the knuckle won't be needed; just change the bearing and flange, now you can run the bigger shafts to accomodate your engine swap! I'll be checking part #'s to see if the prelude Si and Accord SE-i flanges are the same (which i think they are). If so, Prelude Si's will provide a ready source of the oversised flanges, as they sure are a hell of a lot easier to find than the Accord SE-i's are.

Another solution would be to have the 3g flange machined down the 2mm so it fits. i wouldn't want to machine it down 4mm to the original 2g bearing size

That is just friggin unbelievable! Nice job man! I think a write up is in order!

[PhydeauX]

Thats good to hear. I wonder why the SE-i and 2g lude have a .0001 smaller OD? I doubt the tolerences in the hubs are even close enough to make a diference. Anyway good job. Hopefully I'll get that info up into the FAQ in the near future.

I noticed that .0001" difference as well. i think it might be a rounding error when they measured a fractional metric bearing. I also have the pages from the Federal mogul book i was going to scan and post, lots of pertinent info for any honda owner.

[Honda3G]

yo i'm back hello all, oh the forum are very differente now, very nice....

well the status of the new proyect will be posted on time and some other think are out to the light, like some minor problems with the axel and the mount of the driver side was to much out and the left axel it was to short thats why my right axel was to short, alredy fixed now the axels are aligned.

[Ichiban]

Bump!

Hey honda3g, you still around? Hows the car doing?

[2ndGenGuy]

Just thought I'd bump this thread, for the hell of it. Lots of good info, a sticky perhaps? What do you guys think?

[carotman]

Bah, who's going to use the info except you? :p (kidding)

[AccordB20A]

If john is going to be running EFI he may need to install a surge tank if he cannot find a suitable fuel tank with the baffles for the efi.

[Ichiban]

If john is going to be running EFI he may need to install a surge tank if he cannot find a suitable fuel tank with the baffles for the efi.

Why?

[2ndGenGuy]

Yeah why?

[carotman]

bah, you could make your own baffle or use an SE-i fuel tank.

The reason you "need" baffles is because the EFI fuel pump needs a constant pressure to keep the engine running. With a carb car, the float bowl will compensate for the lack of fuel delivery at low fuuel levels

[AccordB20A]

thanks for answering that for me. I wonder if you can make a 3g tank fit?

[2ndGenGuy]

Maybe I'll do that later if I have problems. I'll see if I can get by without it. I don't think MustardCat has had any problems with his EFI conversion.

[Ichiban]

I wonder if the 85 Se-i tanks were baffled. Come to think of it, most EFI tanks I've taken apart have some sort of pot that the pump sits in.
