## Key facts
- Make: Mazda
- Model: RX-7
- Generation: Second generation
- Factory code: FC3S (coupe) / FC3C (convertible)
- Years: 1986 to 1992
- Body styles: 2-door 2+2 coupe with pop-up headlamps (FC3S), 2-door convertible with removable rigid roof panel and folding rear section (FC3C)
- Engines: 1,308 cc 13B-DEI twin-rotor Wankel, naturally aspirated, six-port induction, 9.4:1 compression - 146 hp at 6,500 rpm and 138 lb-ft at 3,500 rpm (Series 4, North America); 1,308 cc 13B-DEI naturally aspirated, Series 5 from the 1989 model year - 160 hp at 6,500 rpm, raised redline and thicker rotor housings; 1,308 cc 13B-T turbocharged, single turbocharger with twin-scroll housing, split intake manifold, air-to-air intercooler and 9.0:1 rotors - 182 hp and 183 lb-ft (Series 4 Turbo II), 200 hp and 195 lb-ft (Series 5 Turbo II); Japanese-market 13B-T rated 182 hp at launch, 202 hp from Series 5 and 212 hp in the Infini limited editions
- Production notes: The figure in general circulation for the second generation is 272,027 cars, stated by Wikipedia and echoed by Old Motors as 'approximately 272,000'. It is not asserted here as settled: no manufacturer source reachable during this research repeats it, and Car Throttle's generation guide states only 'over 250,000 units built'. Mazda's own motorsport archive gives dates rather than volumes: the FC3S coupe October 1985 to October 1991, the FC3C convertible August 1987 to October 1992. Wikipedia dates the same runs September 1985 to December 1991 and August 1987 to December 1992, a difference no source reconciles. Sub-totals are patchier still. Roughly 22,000 convertibles are cited. The 1988 10th Anniversary edition is consistently given as 1,500 cars. The Japanese Infini limited editions ran to four series at about 600 cars each per year, though Wikipedia places them across 1987-1990 and the JDMBuySell buyer's guide across 1989-1992. The American GTUs is worst documented: Wikipedia gives 'between 100 and 1,100', The Truth About Cars 'around 1,100 over two years'. One number circulating as production is not production at all: conceptcarz's '9,743 units' for 1990 is identical to GoodCarBadCar's United States sales total for that year, so it is a sales figure relabeled. Note also that the R1 and R2 designations often attached to this car belong to the third-generation FD, not to the FC.

## Summary
The second-generation Mazda RX-7 replaced the first-generation car for 1986 and ran until 1992, sold in Japan as the Savanna RX-7 and coded FC3S as a coupe, FC3C as the convertible that followed in 1987. Development ran through Mazda's North American design studio with the Porsche 944 as the stated benchmark, and the result was a heavier, better-equipped and far more sophisticated car than the one it replaced: the first RX-7's live rear axle gave way to independent semi-trailing-arm suspension carrying the Dynamic Tracking Suspension System, a passive rear-steer arrangement built into the toe-control hubs. The 1,308 cc 13B twin-rotor Wankel came naturally aspirated at 146 hp and, in Turbo II form, force-fed through a turbocharger with a twin-scroll housing and an air-to-air intercooler for 182 hp, both rising with the Series 5 revision for 1989 to 160 hp and 200 hp. It sold in the largest numbers of any RX-7 and was, for three decades, the generation collectors reached for last.

- Convertible (FC3C, 1987 Japan / 1988 United States): The only factory drop-top in three RX-7 generations, its launch tied by Mazda to twenty years of rotary production. A rigid removable panel over the occupants with a folding rear section. Automatics are common and depress values.
- Savanna RX-7 GT-X / GT-Limited (Japan): The domestic turbocharged grades, sold under the Savanna name Mazda reserved for Japan while export markets used RX-7 alone. Right-hand drive, 182 hp rising to 202 hp.
- Infini I-IV (Japan): Four annual limited series of roughly 600 cars, with Bilstein dampers, BBS wheels, a limited-slip differential and series-specific colors. The final cars were rated at 212 hp, the highest factory output of the generation.

## History

### An RX-7 Drawn for America
The first RX-7 had been a light, cheap, live-axle coupe that sold on novelty. Its replacement, launched in Japan in October 1985 as the Savanna RX-7 and coded FC3S, was deliberately heavier and more conventional, aimed at the market that had bought most of the first ones. Design work ran through Mazda's North American studio in California, the Porsche 944 was the openly stated benchmark, and the finished car carried a quoted drag coefficient of 0.29 at roughly 250 lb more than the car it replaced. Commercially it worked at once. The FC took Motor Trend's Import Car of the Year for 1986, the Turbo II made Car and Driver's Ten Best list for 1987, and the RX-7 took more than a quarter of Mazda's United States sales in its first full year, at 56,203 cars.

### The 13B in Two Tempers
The 13B twin-rotor Wankel measures 654 cc per chamber, 1,308 cc nominal, and appeared in two states of tune that have aged very differently. The naturally aspirated 13B-DEI used six-port induction and 9.4:1 compression for 146 hp, rising to 160 hp with the Series 5 revision for 1989, which also brought thicker rotor housings and a higher redline. The 13B-T dropped compression to 9.0:1 and added a single turbocharger with a twin-scroll housing, a split intake manifold and an air-to-air intercooler fed by a hood duct: 182 hp and 183 lb-ft as the Series 4 Turbo II, 200 hp and 195 lb-ft as the Series 5. Japanese cars were quoted in PS - 185, then 205, and 215 in the Infini series. Precisely when the twin-scroll arrangement arrived is not agreed: encyclopedia and magazine accounts attach it to the Turbo II from launch, while Grassroots Motorsports credits it to the 1989-and-later cars alone.

### Toe Control at the Rear Axle
The engineering the FC is remembered for is not the turbocharger but what Mazda did behind it. The Dynamic Tracking Suspension System replaced the old live axle with independent semi-trailing arms whose hub carriers sat on compliant bushings, allowing the rear wheels to toe out slightly under light lateral load and to toe in once cornering forces passed roughly 0.5 g. It is passive four-wheel steering achieved with rubber rather than actuators, with optional Auto Adjusting Suspension varying damping alongside it. Whether it was a good idea depends on the tire. On period-width rubber and fresh bushings it does what was intended; on worn bushings and modern tire sections it produces exactly the transitional unpredictability it was meant to cure, which is why race preparers fit toe-control bushings that disable the rear steer outright.

### Convertible, Anniversary and the Limited Cars
The FC3C convertible arrived in Japan in August 1987 and the United States for 1988, the only factory drop-top in the RX-7's three generations, with a rigid removable panel over the occupants, a folding rear section and an integral windblocker claimed as a first. Mazda tied its launch to twenty years of rotary production. Above it sat a run of commemorative cars: 1,500 10th Anniversary Turbo IIs for 1988 in monochromatic Crystal White; the American GTU and GTUs of 1989-90, lightened naturally aspirated cars carrying the Turbo's four-piston front brakes and a viscous limited-slip differential to mark the model's IMSA record; four annual Infini series in Japan of roughly 600 cars each; and a 1991 Winning Limited marking Mazda's Le Mans victory with the 787B. The R1 and R2 designations frequently attached to the RX-7 name are not FC cars at all - they belong to the third-generation FD.

### Falling Sales, and the Generation in the Middle
On track the RX-7 was doing better than in showrooms: Mazda counts 100 IMSA wins across twelve years, and the RX-7 GTO took four wins and both titles in 1991. Sales told the opposite story. United States volume fell from 56,203 in 1986 to 38,345, then 27,814, then 16,249 by 1989, and 6,006 in 1992. By then the FD was arriving, and the attention went with it.

## What to look for

Start with a warm compression test read per rotor face rather than as one number. Specialist guidance puts a healthy 13B above 100 psi per face with the faces even; below about 85 psi indicates seal wear and a rebuild in prospect. Hot-start behavior matters as much as the gauge - a long crank on a hot engine points to weak seals or flooding. Then work through the cooling system, because a rotary's tolerance for overheating is close to nil and one event can warp a rotor housing: radiator, fan shroud and clutch, thermostat, coolant loss. Establish which series the car is, since Series 5 cars from the 1989 model year carry the higher outputs, thicker housings and higher redline and price accordingly. On Turbo II cars check turbo shaft play and smoke under boost, and expect to replace the vacuum hose network, which is extensive and brittle. Rust is structural here: sills, arches, strut towers, hatch channel and door jambs, and the rear hatch drain plugs that clog and cause it. Check the front subframe for accident damage, as it resists straightening. Underneath, feel for play in the rear lateral rods and assess the DTSS bushings, worn on most survivors. Second-gear grind is common. Body parts are the quiet expense: nose cones have been quoted around $800. Prefer documented engine work over claimed engine work.

## Common problems

Apex and side seal wear is the defining risk, and it is a wear pattern rather than a fault - low compression from age or neglect means a rebuild. Coolant seal failure is the more damaging cousin: it lets the engine overheat, and overheating warps rotor housings, turning a seal job into a housing job. Buyer's-guide costings put an FC rebuild at roughly $4,000-$9,000 for seal work and $4,500-$10,000 where housings are involved. Supplier pricing in August 2026 sits in the same territory: Atkins Rotary lists a rebuilt 13B at $4,099-$4,699 on used rotor housings and $5,299-$6,699 on new, with the turbocharged 13B at $4,999-$5,199 and $6,499-$6,999 respectively. Beyond the engine: flooding on cold start; overheating in traffic from a clogged radiator, missing shroud or failed fan control; turbo seal wear showing as smoke and low boost; detonation under boost from lean running or heat soak; oil leaks from the front cover, sump and rear main; second-gear synchro wear; and electrical faults traced to poor earths. The eccentric shaft bypass valve that feeds the seals only operates once warm and is worth replacing as routine maintenance. Regulator records for 1986 cars cover front brake caliper corrosion where road salt restricts pad movement, and in Canada a misrouted evaporative purge hose.

## Market notes

As of August 2026 classic.com separates the FC into submarkets that sit a long way apart, and the spread is the story. The Turbo II carries a Market Benchmark of $24,093 against an average sale of $24,729, on a rising trend, with a high of $39,250 recorded on 29 October 2025 for a 1988 10th Anniversary car and a low of $843 in June 2022. The naturally aspirated base coupe benchmarks at $11,460 with an average of $11,623 and is trending down, its recorded results running from $5,000 for a 1986 in May 2025 to $18,257 for a modified 1987 in October 2025. The convertible sits lowest, at a $10,663 benchmark and a $10,931 average on a rising trend, between $3,750 for a 1988 project in August 2024 and $19,999 for a 1991 in March 2026. Across the whole generation classic.com's average sale is $15,681. Auction rooms have been less forgiving: a 45,000-mile automatic 1991 convertible offered at Mecum Kissimmee in January 2024 failed to sell against a high bid of $12,000. For orientation against the generation that followed, classic.com's third-generation FD average sale is $48,593 as of August 2026, with a 1993 R1 recording $127,000 in August 2026 - which places a strong FC Turbo II somewhere near where the FD market begins.

## Value trajectory

The FC spent the 2000s and early 2010s as transport rather than as a collectable, and the record shows it: Grassroots Motorsports quoted $2,500-$6,000 for a decent car and around $1,000 for a project, with hundreds listed at once. A great many were consumed as drift and track cars in that window, which is the single largest reason unmodified, un-swapped survivors are now scarce. The re-rating since has been selective rather than general. As of August 2026 the Turbo II benchmark of $24,093 is rising while the naturally aspirated base coupe at $11,460 is falling, so the generation is separating internally rather than lifting as a whole. Two structural facts hold the bottom down. A rotary rebuild at $4,000 or more can exceed the value of an ordinary naturally aspirated car outright, which caps what a tired example is worth to anyone. And the FD, at a $48,593 average as of August 2026, absorbs most of the money and most of the attention that flows toward the nameplate. What that has produced is a market where a documented, rust-free, manual Series 5 Turbo II moves and everything else waits.
