The Series 3 (1984--1985) featured an updated lower front fascia. North American models received a different instrument cluster (the NA S3 RX-7 is the only rotary-engined car to not have a centrally mounted tachometer). GSL package was continued into this series, but Mazda introduced the GSL-SE sub-model. The GSL-SE had a fuel-injected 1.3 L 13B RE-EGI engine producing 135 hp (101 kW) and 135 lb·ft (183 N·m). GSL-SEs had much the same options as the GSL (clutch-type rear LSD and rear disc brakes), but the brake rotors were larger, allowing Mazda to use the more common lug nuts (versus bolts), and a new bolt pattern of 4x114.3 (4x4.5"). Also, they had upgraded suspension with stiffer springs and shocks. The external oil cooler was reintroduced, after being dropped in the 1983 model-year for the controversial "beehive" water-oil heat exchanger.
The 1984 RX-7 GSL has an estimated 29 highway miles per gallon (8.11 litres per 100 km) /19 estimated city miles per gallon (12.37 l/100 km). According to Mazda, its rotary engine, licensed by NSU-Wankel allowed the RX-7 GSL to accelerate from 0 to 50 (80 km/h) in 6.3 seconds. Kelley Blue Book, in its January--February 1984 issue, noted that a 1981 RX-7 GSL retained 93.4% of its original sticker price.
1985 - Mazda released in Australia the RX7 Finale - this was the last of the series and brought out in limited numbers. The Finale featured power options and a brass plaque mentioning the number the car was as well as "Last of a legend" on the plaque. The finale had special stickers and a blacked out section between the window & rear hatch.
The handling and acceleration of the car were noted to be of a high caliber for its day. This generation RX-7 had "live axle" 4-link rear suspension with Watt's linkage, a 50/50 weight ratio, and weighed under 2500 lb (1100 kg). It was the lightest generation of RX-7 ever produced. 12A-powered models accelerated from 0--60 mph in 9.2 s, and turned 0.779g (7.64 m/s²) laterally on a skidpad. The 12A engine produced 100 hp (75 kW) at 6000 rpm, allowing the car to reach speeds of over 120 miles per hour (190 km/h). Because of the smoothness inherent in the Wankel rotary engine, little vibration or harshness was experienced at high rpm, so a buzzer was fitted to the tachometer to warn the driver when the 7000 rpm redline was approaching.
The 12A engine has a long thin shaped combustion chamber, having a large surface area in relation to its volume. Therefore, combustion is cool, giving few oxides of nitrogen. However, the combustion is also incomplete, so there are large amounts of partly burned hydrocarbons and carbon monoxide. The Exhaust is hot enough for combustion of these to continue into the Exhaust. An engine driven pump supplies air into the Exhaust to complete the burn of these chemicals. This is done in the "thermal reactor" chamber where the Exhaust manifold would normally be on a conventional engine. Under certain conditions the pump injects air into the thermal reactor and at other times air is pumped through injectors into the Exhaust ports. This fresh air is needed for more efficient and cleaner burning of the air/fuel mixture.
Options and models varied from country to country. The gauge layout and interior styling in the Series 3 was only changed for North American versions. Additionally, North America was the only market to have offered the first generation RX-7 with the fuel-injected 13B, model GSL-SE. A turbocharged (but non-intercooled) 12A engine was available for the top-end model of Series 3 in Japan.
Sales were strong, with a total of 474,565 first generation cars produced; 377,878 were sold in the United States alone. In 2004, Sports Car International named this car #7 on its list of Top Sports Cars of the 1970s. In 1983, the RX-7 would appear on Car and Driver magazine's Ten Best list for the first time in 20 years

My 1980 series 1 rx7 stock 12a with new full racing beat street port exhaust!
I got my new Exhaust on! Sounds quiet... But it's ok runs great! She really opened up at about 4500 rpm. Thank you racing beat again! If you call them talk to mike he is the man! It's been 7 years comein! If you like this please thumbs up it! Thanks to jdoublenaz I have a low like value cause someone forgot to change his tampon and got his Honda pants got messy!

MAZDA RX7 Rotary Engine, How It Works
MAZDA RX7 Rotary Engine, How It Works
The MAZDA RX7 rotary or Wankel engine is a marvel of engineering. It has won more races than any other vehicle in its class. Rotary engines develop a great deal of power for their weight (power to weight ratio). They're also able to develop high RPM bursts like no other internal combustion engine. Learn the details of it operation, how the rotor transfers power to the output shaft, what it the stationary gear set, what is the rotor to output shaft ration and relationship. Get all the specifics on the rotary engine's operation here in this video.
