Question for the history gurus:

Was there any offical factory build of the 79 RX-7 that included a 13B engine?

Specifically the RHD GT build?

I second that they were all 12as, now if you are looking for odd engines there was a 12a 6 port and then of course they did also so a 12a turbo but not until 82-83 time frame all of the 79s were 12a

Thanks, that what I'd thought.

Saw a 79 rhd with GT badges at JCCS that claimed to be a"restoration." Didn't see how that could be.

My understanding is that the GT designation was a valid build in Japan... but it would have been 12A equipped based on everything I'd read here and elsewhere.

The "restored" car I saw claimed to be sporting a 13B (I say "claimed" as it was displayed hood-closed only). Can't see how it could be both, was all.

My nit-picking brain was agitated.

people use the word "restored" either loosely or without the adjective. no, some other word, like stock restoration, or restored to the same way it was found in a field or whatever.

Oh boy........... and me without any of my books.....

There are a bunch of JDM specific trim packages, it is really cool to look at the early JDM sales lit and see the things that would soon be in the US.

For 79-80 I know of

S model (very similar to the states however door panels a little different in the arm rest
GS model (again similar to the states)
GT model (trim desingation the interior is basically the same as the US Limited with slight color/cloth variation on the seats also has power mirrors on the fenders and rearview mirror console map light)
Limited model (79 trim designation again between this and the GT there were options one could have the other didn't get)
Limited model (80 basically this is a special combination of a LS us spec and GSL, it has the interior of the US 80 LS model but it also has power windows switches on the doors, power mirrors, LSD, rear wiper, cargo cover, rear seat etc.)

I currently have a 79 GT/Limited..... why do I say it that way, well according to the literature it has the options of the Limited but is branded and trimed to GT standards. It looks like they actually took 2 cars to make one.

I also have 2 other RHD SAs both base models a 78 and an 80

I have been lucky enough years back to be able to fully inspect a JDM 80 Limited

Please no flames if I made some slight errors as I am doing all of this from memory here in IRAQ... at least it gets my mind off other things ..... DAMN what was that big bang LOL

Keep yer head down 'Dude!

S and GS SA 79-80 models is strictly North American designation.
In Japan they initially offered 4 models:
-Limited
-GT - close equivalent to our GS
-Super Custom
-Custom - this was the stripper, but even it got the 5 speed, unlike our "S" version. No clock tho!

In mid/late 79 they finally got the sunroof's available in the Home market (up till then we go them all), which created TWO more sun-roof-equipped models:
-SE Limited - now upgraded to Leather interior and power windows, etc. as the 'Dude sez
-SE GT
6 total including addition to the 4 above mentioned...

Won't bang heads about the various accessories; 'Dude did a great job from memory - I have the benefit of having a handful of JDM brochures right beside me...

Thanks guys,

7aull as I recall and you will have to look at the lit to see if you read it this way also I think one of the big differences between the Limited and GT (79) models was the limited was top scale and you could get the sunroof, on the GT it was similar but sport based the only performance aspect I could see was the lack of sunroof and I think you could only get it with a manual trans ......

You are right on the custom/super custom I couldn't remember the names did you know that there seems to be 3 periods of SA JDM cars at home I have 3 specific groupings of JDM 79-80 lit, I don't want to throw out really bad info but one of the oddities I saw was on the ignitions, for JDM cars i saw the points ing on true 78s (early 79) then before the model year ended (79) they started using electronic ignition like in the 80 cars, and before the 81 restyle came out they started using the later electronic ignition, the SE Limited I saw had 81-5 electronic ignition factory installed

Huh. Did you see this in _person_ or in some Literature? I can't claim to have ALL the JDM brochures for SA but couldn't find any that detailed the ignition system enough to show this change-over. Like most manufacturer's tho, I suspect Mazda isn't immune to on-going upgrades rather than awaiting a proper "new-model-yr" to incorporate the changes. Would be interested in seeing what info you have once your in a position to dig it up...

Stu,

Yea that was what blew my mind on this it was on the SE-limited that I got to see and it was in Korea at the time. I searched all over to try to prove that it wasn't a factory install on the later model ignition but all evidence showed it to be factory.

In response to another question further up about the cats, I am not really sure on the cat issue I know that my euro spec 83 Car basically had a 80 engine in it complete with the thermal reactor as opposed to a cat I am not sure what they were doing on the JDM home market ones I did not pay attention to that part. I know that all of my RHDs have thermal reactors but then they were converted for US useage

Yea I have a few and a few more keep showing up. just remember that the list you are looking at only encompasses the First Gen Rx7s and my collection starts in 1970, we have actually added a few since the last time i updated my registry info.

the EU basically didn't have emissions until the late 80's, mazda had a TR engine in the rx7 until 88 in europe.

i'm under the impression that mazda tries stuff out in japan for about a year before it gets to the US, like the electronic ignition, and i was thinking the catylist too, but i dunno
