SA's only came with a 12A,with the "big top" carb and the intake alot of people like to use on SCCA cars.. It has less emissions.

My first 7 was actually a red 79,with a sun rood and black insides.I didnt like the tail lights so I sold it a few weeks later.

The 13B (fuel injected) ONLY came in the 84/85s which are called series 3.

79-80 series 1
81-83 series 2
84-85 series 3

86-88 series 4
89-91 series 5

I personally like the look of the 84-85 alot better (insides) and they are better built to me.Rear axels are alot stronger/bigger..
84/85 GSL SE have bigger brakes,
steering box is geared diffrent
tranny is geared diffrent
rear end is 4.07 not 3.90 like the other first gens
rear disc brakes
