Editorial notes
Key Takeaways
- Japan's October 1985 launch engine was the intercooled twin-scroll 13B turbo, rated 185 PS net.
- In April 1989 regular grades rose to 205 PS with an independent twin-scroll turbo, and the tail lamps became round.
- FC3S is the coupe code. The cabriolet is FC3C, and Mazda's parts list treats the two separately.
- ∞ (Infini) editions began in August 1986 with two seats, forged BBS wheels, dedicated dampers, an aluminium bonnet, and 300 cars in the first sale.
- Carsensor lists eight ∞ releases; Mazda mentions seven after describing the first. Its counting scope is unclear.
- Mazda reproduces about 90 FC/FD repair parts but warns that some deliveries take time, so check parts early.
Background
Launch and engine
Mazda's history dates the second-generation Savanna RX-7 (FC3S) to October 1985. The engine changed from the earlier 12A to the 13B, a two-rotor unit of 654 cc × 2 with an air-cooled intercooler and a twin-scroll turbocharger. Mazda rated it 185 PS net.
Mazda gives the front-to-rear weight split as 50.5 to 49.5, and the launch size as 4,310 mm long, 1,690 mm wide and 1,270 mm high. The rear suspension became independent semi-trailing arms with a lateral rod, replacing the first generation's rigid axle.
Grades and ∞ editions
The GT-Limited Special Edition was added as the top grade in June 1986. The first ∞ (Infini) followed in August 1986, limited to 300 cars. This two-seat Japanese RX-7 had forged BBS wheels, dedicated dampers and an aluminium bonnet. Mazda describes seven subsequent limited sales through 1991; Carsensor counts eight releases overall, although Mazda's counting scope is unclear.
Web Motor Magazine reports the later ∞ III at 215 PS with higher compression and premium fuel. The Winning Limited of August 1991 marked the Le Mans win and was announced at 1,000 cars, based on the GT-R.
The April 1989 update
Mazda raised the compression ratio, improved the turbocharger and adopted an independent twin-scroll turbo in April 1989. Regular-grade output rose to 205 PS and 27.5 kgf·m, rotors and flywheel became lighter, and the tail lamps became round. Mazda's chronology records a further minor change for the 1990 model year. Mazda's first production rotary turbo came earlier: the Cosmo launched with one in September 1982, and the Luce rotary turbo followed in October.
Cabriolet, production and parts
The FC3C cabriolet was added in August 1987 to mark 20 years of Mazda rotary-car sales. Its roof opens fully, as a targa or closed, and an airboard sits behind the seats. The Final Version followed in August 1992, after the coupe had ended. Inside Mazda gives 272,027 FCs worldwide across all body styles; no Japan-only or cabriolet-only total was found.
Mazda reproduced about 90 FC and FD repair parts but warns that some deliveries take time. For Europe, Mazda UK says the car first arrived with a naturally aspirated 150 PS engine, with 180 PS and later 200 PS turbo versions following. The Mazda RX-7 family covers the other generations.

NHTSA's safety exemption starts 25 years from each car's manufacture date under 49 CFR 591.5(i). EPA's separate age provision requires the original engine configuration or an eligible EPA-certified replacement engine and emissions system. State registration rules vary. Canada counts its 15-year federal age exemption by manufacture month and year. Check the car's documents before shipping. Calculate import costs →

Should You Buy a Mazda RX-7 FC3S?
Why You'll Love It
- Turbo power from launch Japan's 13B turbo was rated 185 PS net from October 1985, then 205 PS on regular grades after April 1989.
- Independent rear suspension Mazda replaced the earlier rigid rear axle with semi-trailing arms, a lateral rod and toe-control hubs.
- Balanced layout Front-mid-engine, rear-wheel drive, with Mazda quoting a 50.5 to 49.5 front-to-rear weight split.
- Factory parts programme Mazda reproduces about 90 FC/FD repair parts for owners.
Why You Might Not
- Parts supply has limits Mazda warns that some reproduced parts take time to deliver and publishes a list of genuine parts nearing the end of procurement.
- ∞ paperwork matters Confirm the ∞ edition and specification against the car's paperwork.
- Two codes, two bodies FC3S and FC3C are separate in Mazda's parts list, so confirm which one you are buying.
- Specs vary by market European cars had different engines and ratings, so do not mix export figures with Japanese ones.
Who Should NOT Buy This
- Anyone who needs a guaranteed supply of every original part: Mazda warns of delivery delays and lists parts nearing the end of procurement.
- Buyers who want one spec sheet for every market: Japanese and European cars differ.
- Buyers paying a premium for an ∞ without paperwork confirming the edition and specification.
Differences between JDM & USDM
Japanese FC3S cars launched in October 1985 with the intercooled 13B turbo at 185 PS net, rising to 205 PS on regular grades in April 1989. Mazda UK says Europe first received a naturally aspirated 150 PS engine, with 180 PS and later 200 PS twin-scroll turbo versions following.
Pre-Purchase Inspection Checklist
These checks rest on Mazda documents and import rules. We do not publish compression limits or repair costs because no Japanese factory figures were found.

Comparable Alternatives
Mazda RX-7 FD3S

Mazda RX-7 SA22C
The first generation. The FC moved from its 12A engine to the 13B.

The Buyer's Read
Start with the edition and build date. The FC3S launched with 185 PS net; regular revised grades reached 205 PS in April 1989. Web Motor Magazine reports 215 PS for the later ∞ III and IV editions. FC3C is the separate cabriolet code.
For an ∞, ask for paperwork identifying the edition and specification. Carsensor lists eight releases; Mazda's wording leaves its counting scope unclear.
Check parts before planning a restoration. Mazda reproduces about 90 FC/FD parts, but warns of delivery delays and lists genuine parts nearing the end of procurement. Match the part numbers for the car.
Ask a rotary specialist for a compression report covering every rotor face and the test method. No Japanese factory pass mark is established here. Check import requirements against the actual manufacture date, including EPA and state requirements for the US. The Mazda RX-7 family covers the other generations.
Frequently Asked Questions
- Was the Japanese FC3S turbocharged?
- Yes. Mazda's history describes the October 1985 launch engine as a 13B with an air-cooled intercooler and a twin-scroll turbocharger, rated 185 PS net.
- What is the difference between FC3S and FC3C?
- FC3S is the coupe code. FC3C is the cabriolet, launched in Japan in August 1987 to mark 20 years of Mazda rotary-car sales. Mazda's reproduced-parts list treats the two codes separately, so quote the right one when ordering parts.
- What changed in April 1989?
- Mazda raised the compression ratio, improved the turbocharger and adopted an independent twin-scroll turbo, lifting regular-grade output from 185 PS to 205 PS. Rotors and flywheel were made lighter, and the car got round tail lamps.
- What is an ∞ (Infini) FC?
- A Japanese limited-edition series first sold in August 1986, initially limited to 300 cars. It introduced a two-seat Japanese RX-7 with forged BBS wheels, dedicated dampers and an aluminium bonnet. Carsensor lists eight releases; Mazda mentions seven after describing the first, leaving its counting scope unclear.
- Was the FC Mazda's first production rotary turbo?
- No. Mazda's first production rotary turbo preceded the FC3S: the Cosmo launched in September 1982, and the Luce rotary turbo followed in October.
- How many FCs were built?
- Mazda UK's Inside Mazda site gives 272,027 for the FC worldwide, all body styles. We found no sourced Japan-only or cabriolet-only total.
- Can I still get parts?
- Partly. Mazda reproduced about 90 FC/FD repair parts, but warns that some take time to deliver and publishes a final procurement list of genuine parts. Check each part number before you commit to a restoration.
