Mazda RX-7: generations, Wankel engine and what to know before buying
Mazda RX-7 — a sporty car produced from 1978 to 2002 with a Wankel (rotary) engine, one of the most iconic Japanese sports models. In this article, we'll look at the three generations, engines, and what to check before buying a used RX-7.
RX-7 in brief
The RX-7 is Mazda's sporty coupe with a rotary Wankel engine — that's what sets it apart from many competitors. Over 24 years of production, three generations were made, each with its own character and fanbase.
This car is praised for its lightweight, well-balanced body, direct steering, and distinctive engine sound. In Lithuania, the RX-7 is rare, with most of the cars available imported from Japan or the USA.
Generations — what sets them apart
The first generation (FB / SA22C, 1978–1985) is a simpler, angular coupe with a 12A rotary engine. The second (FC, 1985–1992) features a more modern design and a 13B engine, as well as a turbo version and a convertible. The third (FD, 1992–2002) is the most rounded and powerful generation with twin sequential turbochargers.
The FD was officially sold in Europe in limited numbers, so most of the cars found there are imports. It's considered one of the most beautiful and hardest to maintain generations, highly sought after by collectors.
Engines and transmissions
All generations of the RX-7 feature a rotary Wankel engine: the first has a 12A, the second and third have a 13B. The FC turbo version produced around 180–200 hp, while the FD managed about 250 hp or more, depending on the market.
The most common gearbox is a 5-speed manual, with an automatic option available for some versions. The car is rear-wheel drive.
What to check when buying a used RX-7
The key question is the condition of the rotary engine: check the compression, inspect for excessive oil and fuel consumption, and ask if the engine has been rebuilt. Rotary engine apex seals wear out and repairs can be expensive.
The body should be free of rust and signs of previous accidents, and the cooling system and turbo vacuum lines should operate smoothly. Proper vacuum system operation is especially crucial for the FD. Consider hiring an RX-7 specialist before purchasing.
