Quick answer
Mazda sold the RX-7 in Japan in three generations: the SA22C from March 1978, the FC3S from October 1985 and the FD3S from December 1991. All three used Mazda rotary engines, and Mazda's chronology records production ending in August 2002. Check the chassis code, grade and build date.
Background
The SA22C went on sale in March 1978 as the Savanna RX-7, in Custom, Super Custom, GT and Limited grades. Its 12A (573 cc × 2) was rated 130 PS gross, and the launch GT seats four. A turbo version was added in September 1983, at 165 PS gross in Mazda's Japanese history and 160 PS in Mazda UK's retrospective.
The FC3S went on sale in October 1985 with a 13B (654 cc × 2) and an intercooled twin-scroll turbo rated 185 PS net. An independent semi-trailing-arm rear suspension replaced the SA22C's rigid rear axle. Regular grades reached 205 PS at the April 1989 minor change, and Web Motor Magazine lists the later ∞ III at 215 PS.
The FD3S went on sale in December 1991 with the 13B and sequential twin turbochargers, rated 255 PS. The headline rating rose to 265 PS in January 1996. Type R and RS reached 280 PS from 21 January 1999, while Type RB stayed at 265 PS with the manual and 255 PS with the automatic.
In Japan the SA22C and FC3S were sold as the Savanna RX-7. The FD3S launched as the Anfini RX-7, and Mazda renamed it the Mazda RX-7 on 14 October 1997. Mazda UK's retrospective calls the first generation the FB platform; this guide uses Mazda Japan's SA22C code.
Seating depends on the grade. The SA22C launch GT seats four. Mazda describes the first FC3S ∞ edition, of August 1986, as a two-seat Japanese RX-7. Of the FD3S Spirit R, Type A is a two-seater and Types B and C have four seats.
Mazda describes the rotary engine as one where a triangular rotor rotates to generate power. Its FAQ says the design needs fewer parts than a conventional engine and makes the engine small and light. The first Mazda vehicle with a rotary engine was the Cosmo Sport, introduced in 1967 (see the Cosmo guides). The RX-8 followed in April 2003 as a separate model.

Constants
Chassis history
Dates are Mazda's Japanese sale dates. Mazda's chronology records production ending in August 2002; exact first and last build dates are not established for any generation.
Identification
Generation names are broad families. The factory chassis codes below identify the variants represented in JDMBUYSELL's current Mazda RX-7 guide data.
Confirm the complete code on the vehicle's frame or VIN plate; drivetrain, body, and market variants can use different prefixes within one generation family.

Reliability
UK buying-guide advice from Hagerty and PistonHeads, not Japanese failure rates.
| Issue | Cause | Solution |
|---|---|---|
| SA22C corrosion and scarce panels | Hagerty UK lists the wheelarches, inner wings, sills, floorpans, door bottoms, windscreen surround, boot floor and suspension mounts; replacement panels and new interior parts are scarce. | Inspect those areas closely before buying. |
| FD3S air-separator tank leak | PistonHeads says the air-separator tank can split and leak coolant. | Inspect the cooling system before judging engine condition. |
| FD3S turbo-control ageing | PistonHeads says under-bonnet heat can damage the turbo solenoids and rubber pipes, causing erratic sequential operation. | Check the solenoids and pipes. |
| Flooding after short runs | PistonHeads says very short start-and-stop use can flood the engine; hard starting alone does not identify an apex-seal failure. | Have a rotary specialist diagnose the cause. |
Market
This guide describes Japanese-market cars. Export cars differ. Mazda identifies a 1984 US GSL-SE with the fuel-injected 13B in place of the Japanese turbo. Mazda UK describes European FCs with a naturally aspirated 150 PS engine first, followed by 180 PS and later 200 PS turbo versions, and gives 239 PS for the European FD. Do not apply export ratings or grade names to Japanese cars.
Specs
Japanese-market ratings. Mazda states the SA22C figures as gross and the FC3S launch and FD3S 280 PS figures as net, so do not compare the rows directly.
Custom, Super Custom and Limited were also launch grades.
Mazda's two sources disagree and the cause is not established.
The later ∞ III is listed at 215 PS.
Mazda's history gives 265 PS for the January 1996 revision without a grade-by-grade breakdown.

Editorial
Start with the chassis code and the build date. The SA22C is the 1978 car with the 12A and a turbo version from September 1983, the FC3S coupe and FC3C cabriolet are separate codes, and the FD3S was rated 255, 265 or 280 PS depending on grade and date.
For any RX-7, PistonHeads' buying guide makes a rotary-specialist compression test the starting point and notes that all rotary engines use oil. For the FD it also names the air-separator tank, the turbo solenoids and the rubber pipes. Hagerty UK's guide to the first generation lists the wheelarches, inner wings, sills, floorpans, door bottoms, windscreen surround, boot floor and suspension mounts as rust spots, and says replacement panels are very thin on the ground.
Then work out the car's age from its own manufacture date. The US 25-year rule counts from manufacture (49 CFR 591.5(i)), EPA expects the original engine configuration or an equivalent or newer EPA-certified engine and emission-control systems, and Canada counts 15 years from the month and year work was completed at the place of main assembly.
