I just Picked up another 7. Its a 79 but im not sure which model it is how can i find out ? Also u think i should work the 12A, or do a 13B swap? Which one will cost less and which will give me more power. Plz give me pros and cons. Thanks guys.

 

'79 only had one model.

 

Double post.

 

i knew a guy who had the 4 speed tranny, i have the 5 speed, is that the only difference ?

there was also a 3speed automatic... Not that we care about such things

But I don't htink there were any other models....

(Victoria British has a little history section in the catalog... that's all it mentions except later '79 models havign a passanger side mirror)

 

The 79 did to have more than one model..... it had two: S, GS. I think the difference between the two are alloy rims and a 5 speed on the GS vs steel rims and a 4 speed on the S.

You probably have a GS.

 

there where a few more differances in the two models for that year but absolutely a g and a gs model for us in 79. g models stricly only had a 4 speed. gs came standard with supension bars ,alloy wheels, pass side mirror, five speed transmission . I have not seen a 79 gs with out a sun roof this may have been standard on gs also. my 79 gs also came with a sport pkg the center of the alloy wheels were gold air dam on front and a rear spoiler called a duck tail very simlar to the three piece imsa one that came on latter years

 

The basic model is called "S" not "G" and your correct, 79 only had S, and GS models, as did 80, the only exceptions being a few limited production models, such as the 79 Limited Edition, 80 Leather Sport, and Anniversary X edition.

 

damn lucky you I'd love to have that

Known as an 'SA' type due to its VIN number, the 1979 model (released in 1978) was the first of the RX-7 line.

Mazda aimed to make a true sports car and not repeat the errors of the Rx5 Cosmo. The chassis would be a monocoque with the unbelievably high torsional strength of 6,780lb-ft per degree, a figure which turned out to be something of a challenge to better in the second generation Rx7.

The RX-7 debuted in the spring of 1978, production started in March and introduced as a 1979 model. Road & Track compared its impact to the instantly successful 1970 introduction of the Datsun 240Z, subtitling it's initial article on the rotary-powered sports car "A major
breakthrough for the enthusiast". It was, the magazine noted, the first such vehicle since the demise of the original Cosmo Sports and the NSU Prinz.

The RX-7 was praised for ventilation and heating (a Mazda tradition), including the then novel idea of demisting the side glass by separate vents at the A-pillar.

Models

S

The Sport (S) was not a stripped loss leader. Standard equipment on the $6,395 base model included AM/FM stereo radio with electric actuated antenna, tinted glass, quartz clock, rear defogger, and HR-rated 165-13 steel belted radials from Bridgestone.


GS

The Grand Sport (GS) package was $600 more, offered a lot of functional stuff: the 5-speed gearbox, 185/70-13 Bridgestones, the rear anti-roll bar, and a 4-spoke (instead of the base's 2-spoke) padded steering wheel, as well as an electric hatch release, a day-night mirror, and miscellaneous trim bits including side molding not on the base model.

Aluminum alloy wheels were not included in the GS package - the standard wheel was a 5" wide styled steel rim painted an aluminum/gray color. The optional 5.5"-wide alloys added to the sticker price, and the intricate design added a lot of time to a car wash to get all the road dirt and brake pad dust from all the nooks and crannies. Other freestanding options were the automatic transmission, air conditioning, stereo cassette sound system, a rear spoiler, and California emissions.

LE

The Limited Edition, sold in small numbers, had cosmetic differences.

 

ty manntis for the X details. I think Then it is the gs , although
kuhlrx7 u say that u never seen a gs without a sun roof, this one does not have one
i dont know what to do first, it does run but when i give gas it like sputters and exhaust sounds awful. I did buy some goodies for it already, but mostly interior and exterior parts, nothing under the hood yet. It just sittin right now. when i get more ill start this project, prolly in the fall.
