Abbreviations.
Alright. Call me a newbie and all that for this post.
I understand that there are the generations of the RX-7; and that each generation has additional separations of model types.
The first generation has three models:
The base model, or "S"
The slightly more upgraded model, the "GS"
and the model with a sunroof and rear windshield wiper, the "GSL"
In addition to these there are others such as the "GSL-LE" and the "GSL-SE"
I'm not sure of the difference other than (maybe) having the 13b engine instead of the 12a.
I've realized that 13bt means the 13b turbo motor...
In this forum I have heard other abbreviations such as SA, FB, FS, FC, TII, SP......are there any that I'm forgetting?
Anyway, I'd appreciate it if someone could clear these up for me. Then I can get to work in understanding the second generations......

Have RX-7, will restore

there's no GSL-LE, only GSL-SE. 13B rear disc, limited slip, beefier trans, EGI(electronic gas injection aka fuel injection),
SA-79-80 rx-7. VIN began with the digits SA22C...
FB-81-85 rx-7
FC-86-91 rx-7
FD-93-95 rx-7 (continued until 2002, not available stateside)
FS-for sale
WTB-want to buy
TII- second gen rx-7 that had the turbo engine. it was called the "TURBOII"
SP-streetport- level of porting that is very common and yields good results with reliability, idle quality, and tuneability.
this should be a good start to help you out in your abbreviations. any more you can think of, just ask.

Take a look at a terms list taken from the 2nd Gen section. Not all of this pertains to 1st Gens, but still good to know.

Terrified.
I thought the 79 was just a limited?
Regardless, the 1983 LE pretty much gives you a special color and 14 inch rims, which are the sexiest stock SA/FB rims you can get imo (imo=in my opinion).

1979 - S, GS, LE
1980 - S, GS, LS
1981 - S, GS, GSL
1982 - S, GS, GSL
1983 - S, GS, GSL, LE
1984 - S, GS, GSL, GSL-SE
1985 - S, GS, GSL, GSL-SE
The '79 LE was a GS with a few cosmetic differences.
The '83 LE was chateau silver w. red pinstriping, 5.5" wide special alloy wheels, pop-out sunroof, cruise control, "plush" red velour interior, air conditioning, and a special sound system with a four speaker ETR/AM/FM stereo/cassette, Dolby noise reduction, and seven-band graphic equalizer.

Engine porting abbreviations:
SP - street port, ports are enlarged over stock port, can still be driven on the street
BP - Bridge port, the intake ports were made so big that the corner seals would fall into them, so a thin bridge of metal was left in the side housing for the corner seal to ride across the intake port. This is a high rpm, racing only port job. Not used on the street because of poor low rpm performance, and most street driving is done at low rpms. Bridge ports are used in racing classes that do not allow peripheral porting.
PP - Peripheral port, a racing only intake port. The stock intake ports in the iron side housings are filled in with Devcon epoxy; they are no longer used. A new intake port in the periphery of the rotor housing is bored right thru the side of the housing, giving a nice straight path for the intake charge to rush into the engine. Not used on the street because of poor low rpm performance, and most street driving is done at low rpms. Peripheral ports make the most horsepower of any naturally aspirated rotary.
Altering the port shape on a rotary can have the same effect as changing the cam profile in a piston motor. You can shift the power band to higher rpms and make more power, but always at the expense of smooth low rpm operation.
