Mazda RX-7 FC3S Turbo II
The second-generation RX-7, known as the FC3S, was a significant step forward from the original FB in every dimension. The Turbo II variant, featuring a twin-scroll turbocharged version of the 13B rotary engine, was the performance flagship — a car that could compete with European sports cars costing significantly more.
The 13B-T engine displaced 1,308cc (equivalent) and featured Mazda's twin-scroll turbocharger system, which directed exhaust gas from each rotor to separate scroll paths before combining at the turbine. This reduced lag and improved low-RPM response compared to a conventional single-scroll design. Output was 200 horsepower at 6,500 rpm and 266 Nm of torque at 3,500 rpm — strong figures for the era.
The FC platform was a complete redesign. The chassis used independent rear suspension for the first time in an RX-7, with a semi-trailing arm arrangement that significantly improved handling precision and ride quality over the FB's live axle. The front suspension retained the MacPherson strut layout but with revised geometry. The overall weight was approximately 1,250 kg — heavier than the FB but still light by sports car standards.
The styling, created under the direction of the Mazda design studio, was a significant departure from the FB. The flowing, curved body eliminated the pop-up headlights of some variants (though they returned in certain markets) and featured a distinctive hatchback profile. The Turbo II received a prominent hood scoop for the intercooler and wider body-colored bumpers.
The interior was significantly upgraded, with power windows, air conditioning, and a more comprehensive instrument cluster including a boost gauge. The seats were supportive and comfortable, and the overall driving position was good. The five-speed manual gearbox featured a precise shift action that complemented the engine's eager character.
The FC Turbo II could accelerate from 0-60 mph in approximately 6.5 seconds and reach a top speed limited to 245 km/h. On a twisting road, the combination of light weight, responsive turbo engine, and competent chassis made it a genuinely rewarding car to drive quickly.
The FC RX-7 was produced from 1985 to 1991, with the Turbo II available throughout most of the production run. Total FC production was approximately 272,000 units. Today, the Turbo II is the most sought-after FC variant, appreciated for its balanced performance, engaging driving character, and increasing rarity of unmolested examples.
Rotary engine compression test on each face is essential. Check turbocharger condition — shaft play and oil consumption. Rust in lower fenders, rear quarters, and hatch area. Verify that the car is a genuine Turbo II (not a naturally aspirated model with aftermarket turbo). Cooling system must be in good condition. Original, unmodified examples are becoming rare.
Produced at Mazda's Hiroshima factory from 1985 to 1991. Total FC platform production was approximately 272,027 units across all variants and markets. The Turbo II was the performance flagship of the range.
