The Mazda RX-7 was produced across three distinct generations from 1978 to 2002, each with its own engine variants:
The original RX-7 launched in 1978 as the SA22C (early production, also called Series 1, 2, and 3) and continued as the FB (after 1981 refresh). Engine options across the SA22C / FB generation:
| Engine | Years | Configuration | HP | Notes |
|---|---|---|---|---|
| 12A | 1978-1985 | 2-rotor 1.1L NA | 100-135 HP | The original RX-7 engine, naturally aspirated |
| 12A Turbo | 1983-1985 (JDM) | 2-rotor 1.1L Turbo | 160 HP | JDM-only turbo variant |
| 13B | 1984-1985 | 2-rotor 1.3L NA | 135-160 HP | Optional upgrade engine, US GSL-SE trim |
The SA22C / FB RX-7 was the car that introduced rotary power to the mainstream US sports car market, selling over 470,000 units worldwide across its 7-year run.
The FC RX-7 (also called the Series 4 and Series 5) introduced more advanced styling and the first turbocharged RX-7 sold in the US. Engine options:
| Engine | Years | Configuration | HP | Notes |
|---|---|---|---|---|
| 13B NA | 1986-1988 (early FC) | 2-rotor 1.3L NA | 146 HP | Base FC engine |
| 13B-T (FC Turbo) | 1986-1991 | 2-rotor 1.3L single turbo | 182-200 HP | The legendary FC Turbo |
| 13B-T (Convertible) | 1988-1991 | Same as FC Turbo | 182-200 HP | Convertible body |
| 13B-T (Series 5 Refresh) | 1989-1991 | Updated 13B-T | 200 HP | Refined FC Turbo with improvements |
The FC Turbo became iconic for its turbocharged rotary performance at an accessible price.
The FD RX-7 represents the pinnacle of rotary sports car engineering and one of the most acclaimed sports cars ever produced. Engine options:
| Engine | Years | Configuration | HP (US) | HP (JDM) |
|---|---|---|---|---|
| 13B-REW | 1992-1995 (US) | 2-rotor 1.3L sequential twin-turbo | 255 HP | 252-265 HP |
| 13B-REW (continued) | 1996-2002 (JDM only) | 2-rotor 1.3L sequential twin-turbo | N/A (not sold in US after 1995) | 276 HP (final JDM spec) |
The 13B-REW is the legendary sequential twin-turbo rotary that defined the FD's character. The US received the FD from 1992-1995 only, with peak output 255 HP. JDM markets continued FD production until 2002 with the final 1999-2002 "Spirit R" producing the official 280 PS (276 HP) rating under the Japanese gentleman's agreement (actual measured output was approximately 280-300 HP).
The crown jewel of Mazda's rotary engineering is the 13B-REW sequential twin-turbo system used in the FD. How it works:
The sequential twin-turbo system was technically complex but produced the rolling boost power delivery that defines the FD RX-7 driving experience. The same system was used in the Eunos Cosmo, scaled up for the 3-rotor 20B engine.
