what used a 13b?
 

what cars & years used a 13b?

Rotary Engine Pick Up
RX-3SP
RX-4
RX-5/Cosmo
Some late model Cosmo's
Some 84 & 85 RX-7
Everything USA from 86 on
Did I miss anything?

13b's
 

wow thats a lot. when did it go out of production?
Where can I find a serial no on the case?

Actually to my knowledge rx3 sp came with 12A...

Correct Nick...all rx3's came to America with 12a's.... some had 10a's over sea's

parkway bus

Nope.. 12A ;)
Atleast, the 2 I've seen in person were 12A

I was pretty sure the Parkway bus was 13B. I think the US spec series 3 FB RX-7's had the option of 12A turbo or 13B 6 port whereas the SA models from series 1 to 3 were all 12A, that's my understandng anyway. Or are series 1 & 2 SA and series 3 FB for the US?

Going a bit off topic, A lot of people over here have a tendancy to call all the first gen RX-7's FB instead of SA (we only got the 12A powered SA first gen RX-7 here).


Keith ;)

rx3 sp is 12a and parkway bus is the 13b

.. you have left out all of the HB cosmo series ( used 13b RESi, 12a 6p and 12at )
HC cosmo ( 13b RE and 20B )

and rx9 ( the european double overhead headlight 929 before HB cosmo )

and the holden roadpacer

and rx8...FC rx7, FD rx7 ... and the H2 13b premacy vans

roadpacer

They aren't all SA either...
There is no such thing as a 13b SA ;)

'78 - '80 is SA which is series 1
'81 - '83 is FB which is series 2
'84 - '85 is FB which is series 3

The VIN changed in 81, hence the different name

Yea I agree with SA's not being 13B. Maybe it's different in different countries? I was under the impression (any Aussie guys feel free to correct me if I'm wrong) that:

78-80 Series 1 is SA with 12A
81-83 Series 2 is also SA with 12A
84-85 Series 3 "Aussie spec" SA with 12A
84-85 Series 3 FB with 12A Turbo or 13B 6 port for US (and other?) market.

Therefore it would seem correct that any 12A Gen1 RX-7's should be an SA for the Aussie market?


Keith ;)

Regular RX-3 had a 12a all of the SP's had 13b's, that's what made them special.

No RX3 Sp came with a 13B from the factory. .. they all came with 12A. What made RX3 SP special was the appearance package. 13B came on the RX4, RX5/Cosmo, REPU. Then it disappear till the gslse.

No RX-3 ever left the factory with a 13B engine. Not all RX-3SP's had the appearance package either.


Keith ;)

Your right just checked the RX-3 SP manuals and it's 12a all the way. Must be old guy syndrome.

just wondering, was every US '77 and '78 Rx3 an SP?

All rx3 from 8/76 thru 78 were sp's... Even if it didn't have the appearance package..

sp
 

none of the sp's came with rear window that rolled down and from what i have been told there is a calif. model that had shortened rain rails on the a pillar

I had an 808 parts car that had the shortened rain rail and non roll down rear windows... think it was a 76... maybe Mazda changed all of them????

serial no
 

where can I find the s/n on the block of a 13b

They don't have serial numbers or anything that can prove it came with a specific VIN. The only thing we have are design attributes.

your funny tony

I don't believe that you saw one of the 44 parkway 26 buses ever produced and it was 12a model to boot
