20B engine for sale, Alabama

[BlueflameFE]

I'm selling this 20B engine that came out of my JC Cosmo when it was restored. The owner before me put everything new under the hood. This is a low mileage engine that ran until they took it out for the new one. If you are interested let me know. I'll entertain reasonable offers. I also have the stock computer from the cosmo that I'll include if the price is right.

Thanks,

Dan

I so wish I could get this....GLWS

[Whizbang]

do you have a rough price in mind? also even MORE important, do you have the counterweight for it?

[Brent]

Also interested in a price. Did you get compression numbers by chance before it was pulled? How long since it has been running/pulled from the car? Thanks.

I'd like to have at least $3,500. And I have a store room full of the extra parts and new back-up parts for the Cosmo. Can you tell me what the counterweight looks like? I've never built or installed an engine.

Don't have compression numbers, and it was pulled 3 years ago I believe. Would like at least $3,500.

so for 3500 it comes with the manifolds and related then?

Give me a list of exactly what you would want with it and I'll see what i have here.


Where would I find what series it is?

[To_Slow]

From looking at the pics its an early series engine. will be a great NA application. 3500.00 is a bit much, for an early series motor, but gl with the sale.

where 13b is cast on the rotor housings look at the number/letters stamped right below that. then post

You mean where the "20B" is cast, the serial number is to the right of that. Looks like "B03" to me but then I don't think that can be right as it should be "B" plus three digits. Might not be a "B" so it could be three digits only.

We'll see.

OK, the engine is 503 series. If you zoom in on the pic you can see it.

Also, I had emailed the previous owner about the condition of the engine. Here is an excerpt of what he said:

With regard to the engine...I don't recall the mileage, but the only reason to keep the motor is because it was the original motor in the car. And if you were ever going to restore it to original, original, original, then you would need to rebuild it and reinstall it. Anyone who knows anything about Cosmos will know that a 1990 would have a three digit numbers only motor xxx, perhaps a late 90 would have a Axxx series motor, but that might be pushing it. The original motor lasted so long because it was a diplomat's car, driven in the U.S. and was never abused. So given those facts, you will have to decide if keeping the motor with the car has some future value - not to you necessarily, but to a future owner or collector. I haven't checked lately, but the supply must be getting low, which means the prices may have gone up.


I will take offers on the engine.

I kind of agree. I have an early series (Number series) and I'm planning to do an NA instead of a turbo.. You could do a turbo but I would prefer C or D.... or E.

[Whizbang]

if it has the counterweight for that engine i might be tempted to work something out in the next couple weeks. But without the counterweight you really cant use it since there will be no way to attach a flywheel or anything.

The one in the Cosmo now is a D.

As the engine is "503" with no letter, it is an original run engine and as such, is the least desirable of them all due to problems Mazda had with these engines failing. The problem is with the irons and these were redesigned in the B series and greater engines. FYI - I have C339 which makes me happy. From the "other" forum:

I do not know the total numbers of "runs" that were
made but it goes like this:
the first run went from 001 to 999
then the next run was A 001 to A 999
there may have been more than 1000 per run but this is
what I have seen.
next came:
B 001 to B 999
then last was:
C 001 to C 999 (actually D was the last series)
the differences between the run numbers are strength.
the first 2000 motors were the first run and are the
ones that mazda had the problems with, and had
changed lots out on warranty to the newer motors
at great expense.
I was told that the first run motors have a short life
and its not a matter if they will fail, rather when,
especially under higher boost levels (anything over 12psi)
the strengthened housings of te 2nd run (B toC)
make the motor much more reliable and hold higher boost.

[Herblenny]

I thought it started from C series not B (stronger engine).. But its been awhile. I have a number and a "D" series engine.

Also to add, There are few "E" series. Some say this was the last series Mazda made and used mainly as a replacement engines for Eunos Cosmos. I have seen only one photo of E series engine.

[BlueflameFE]

I'm learning a lot!

The middle of the B series engines were stronger. E series are the replacement ones without any numbers and the black rotor housing area.

Thanks for the info guys.

After hearing the bad news, damn. I was kinda interested too, being in LA not too far from you and about to get my reenlistment bonus =(

I am sure it went for more than that. He ended the eBay bidding because it looks like he sold it elsewhere.
