Overview
The FD (chassis code FD3S) is the third and final RX-7, and arguably the purest expression of Mazda's rotary dream: a low, light, 50:50 two-seat coupe powered exclusively by the 13B-REW - the world's first mass-produced sequential twin-turbo engine. Every FD ever built used this one 1.3L twin-rotor; there is no other engine, so the 'variants' here are the series/spec levels Australians actually buy. Australia got the Series 6 officially from 1992 (around 176kW, five-speed manual only, no auto was ever sold here), the legendary Series 6 RX-7 SP homologation special in 1995 (just 35 built, ~204kW/357Nm, lightweight, for the Bathurst 12 Hour which Mazda won), and the facelifted Series 7 from 1996 to 1998 before Mazda withdrew the car from the local market. The Series 8 (1998-2002) was never sold new here but is extremely common as a Japanese grey import, which is why it falls inside the 1992-2002 span. These are now appreciating modern classics and prices are strong - but the rotary is fragile and unforgiving: apex seals, the notorious 'rat's nest' of vacuum lines controlling the sequential turbos, chronic underbonnet heat and a stock cooling system that struggles all mean a neglected FD can need a full engine rebuild ($12k-25k+) without warning. Buy on compression test and documented rebuild history, not on looks.

Timing chain / belt / gear
No timing belt/chain - eccentric shaft is gear/chain driven internally; not a service item
Pros
- The original, lightest, purest FD - the enthusiast's pick
- Sequential twin-turbo gives near-seamless boost when healthy
- Sublime balance, steering and chassis - a genuine 90s icon
- Officially Australian-delivered with local compliance and history
- Strong and rising values as a modern classic
Cons
- Apex seal / rotor wear leads to expensive rebuilds, often by 120-150k km
- The 'rat's nest' of vacuum lines/solenoids degrades with heat and disrupts boost
- Stock cooling system is marginal - overheating is a real risk
- Manual only; no auto was sold in Australia
- High running costs, frequent oil top-ups, specialist-only servicing
Known problems
high
Apex seal failure / loss of compression
The rotary's apex seals wear or break, usually from oil starvation, detonation/pre-ignition or overheating. Symptoms are hard cold starting, rough idle, blue smoke and a failed/uneven compression test. A worn rotary cannot be 'patched' - it needs a full engine rebuild.
Fix: Compression test before every purchase. Rebuild with quality (often 3mm) apex seals by a rotary specialist; maintain oil level, use premix or a working oil-metering system, never lug or overheat the engine.
high
Sequential turbo 'rat's nest' vacuum/solenoid failure
The sequential twin-turbo system is controlled by 8+ vacuum solenoids and a maze of small hoses that harden, crack and leak with underbonnet heat. Leaks cause poor secondary turbo transition, boost spikes, flutter, flat spots or limp running - and dangerous overboost can hurt the engine.
Fix: Full vacuum hose ('rat's nest') replacement with silicone lines, test/replace solenoids, verify charge-control and pre-control actuators. Many owners simplify to a single-turbo conversion.
high
Overheating - marginal stock cooling
The stock radiator and cooling are barely adequate; cracked radiators, warped/perished turbo coolant hoses, a failing expansion tank or a tired thermostat let temps climb. A rotary that overheats can lose its coolant (corner) seals and apex seals.
Fix: Fit a high-capacity alloy radiator, fresh hoses, new thermostat and good fan/shroud; never run a hot rotary hard. Watch the gauge religiously.

Engine
1.3L twin-rotor Wankel, sequential twin-turbo (uprated SP spec)
Config
Twin-rotor sequential twin-turbo
Displacement
1308cc (2 x 654cc rotor)
Power
204kW @ 6500rpm
Torque
357Nm
Drivetrain
Rear-wheel drive (RWD)
Economy
13-17 L/100km real world (track use far higher)
Transmission

Timing chain / belt / gear
No timing belt/chain - eccentric shaft is internally driven; not a service item
Pros
- Genuine Australian-built homologation special - only 35 made
- Uprated to 204kW/357Nm with a larger intercooler, bigger radiator and 120L fuel cell
- Lightweight bonnet, seats and trim - a true road-legal race car
- Holds Bathurst 12 Hour history; the most collectible Australian FD
- Improved cooling over a standard Series 6
Cons
- Extremely rare and very expensive; values well into six figures
- Same fragile rotary internals - a rebuild is just as costly
- Many have been modified or raced; provenance is everything
- Hard-driven examples can have heavily worn engines
- Parts for the unique SP-specific bits are scarce
Known problems
high
Apex seal / rotor wear (often track-stressed)
As with any 13B-REW, the apex and corner seals wear and the engine eventually needs a rebuild; SP cars were built to be raced, so many have had a harder life than standard road FDs.
Fix: Demand compression figures and documented rebuild/race history; budget for a specialist rotary rebuild.
medium
Provenance / authenticity risk
With only 35 built and high values, mis-described 'SP-spec' or replica/converted cars exist. Buying the wrong car is a five-figure mistake.
Fix: Verify build number and documentation; use a marque expert/club to authenticate before purchase.
Series 7 13B-REW (1996-1998)
Engine
1.3L twin-rotor Wankel, sequential twin-turbo (facelift)
Config
Twin-rotor sequential twin-turbo
Displacement
1308cc (2 x 654cc rotor)
Power
Up to 206kW @ 6500rpm
Torque
Up to 314Nm
Drivetrain
Rear-wheel drive (RWD)
Economy
12-16 L/100km real world
Transmission
5MT
Timing chain / belt / gear
No timing belt/chain - eccentric shaft is internally driven; not a service item
Pros
- Facelifted FD with revised aero (taller rear wing) and updated interior
- Improved engine management and slightly higher output than early S6
- Last factory-delivered RX-7 in Australia
- Same brilliant chassis and balance
- Strong collector demand
Cons
- All the rotary fragility of any FD remains
- Heat-soak and vacuum-line degradation unchanged
- Manual only in Australia
- Specialist servicing essential; running costs high
- Late local cars are now 25+ years old - condition varies wildly
Known problems
high
Apex seal failure / compression loss
Identical rotary wear pattern - apex and corner seals degrade, giving hard starting, smoke and low compression that mandates a rebuild.
Fix: Compression test pre-purchase; rotary specialist rebuild; disciplined oil and cooling maintenance.
high
Vacuum/solenoid 'rat's nest' degradation
The sequential-turbo control hoses and solenoids harden and leak, upsetting the primary-to-secondary turbo transition and boost control.
Fix: Replace the full vacuum system with silicone lines and test all solenoids; some owners convert to single turbo.
medium
Carbon build-up / weak compression from short trips
Rotaries dislike cold short trips and idling; carbon deposits can cause pre-ignition and accelerate seal wear, and flooding a hot-restarted rotary is a known way to foul plugs.
Fix: Warm thoroughly before load, give regular spirited (not abusive) runs, fresh plugs, and follow correct hot-start procedure.
Series 8 13B-REW (1998-2002, grey import)
Engine
1.3L twin-rotor Wankel, sequential twin-turbo (final JDM spec)
Config
Twin-rotor sequential twin-turbo
Displacement
1308cc (2 x 654cc rotor)
Power
Up to 206kW @ 6500rpm (280PS JDM)
Torque
Up to 314Nm @ 5000rpm
Drivetrain
Rear-wheel drive (RWD)
Economy
12-16 L/100km real world
Transmission
5MT, 4AT
Timing chain / belt / gear
No timing belt/chain - eccentric shaft is internally driven; not a service item
Pros
- Final and most developed FD - best electronics, ABS and cooling tweaks
- Hit the full 206kW/280PS JDM output
- Desirable trims (Type R, Type RS, Spirit R) come as imports
- Common and affordable to find via the Japanese import market
- Auto was offered in Japan (rare) for those who want it
Cons
- Never sold new in Australia - grey import, so check compliance and history
- Same fragile rotary - rebuild costs are unchanged
- Import histories can hide accident damage or tired/modified engines
- JDM speedo/odometer in km but verify genuine mileage
- Auto saps the rotary's character and is rare/hard to service
Known problems
high
Apex seal failure / engine rebuild
The same rotary wear applies, and on imports the true engine condition and history are often murky. A 'fresh' import can be one bad compression test away from a rebuild.
Fix: Independent compression test and pre-purchase inspection; treat undocumented imports with caution.
medium
Import provenance / odometer and accident history
Grey imports can carry undisclosed accident repairs, modified engines or wound-back odometers from the auction chain.
Fix: Obtain the Japanese auction sheet, verify compliance plate and import paperwork, and inspect for prior crash repair.
high
Vacuum/solenoid and heat-soak issues
Even the latest FD keeps the complex sequential-turbo vacuum control that degrades with heat and age, plus the marginal cooling.
Fix: Refresh the vacuum system and cooling; verify sequential transition on a test drive.
Common problems (all variants)
high
Chronic underbonnet heat soak
The FD packs a hot turbocharged rotary into a tiny, tightly sealed engine bay. Heat cooks the vacuum hoses, wiring, coolant hoses and the radiator, and is the root cause behind many FD failures - including coolant seal and apex seal damage.
Fix: Upgrade radiator/cooling, replace heat-perished hoses and lines, fit heat shielding/venting; never shut a heat-soaked engine down hard after a hard run.
high
High oil consumption is normal - low oil is fatal
Rotaries deliberately inject a small amount of oil into the combustion process to lubricate the seals, so they always use oil. Owners who do not top up - or who delete the oil-metering system without proper premix - starve the seals and destroy the engine.
Fix: Check oil every fuel stop, keep it topped up, use the correct oil, and never run an OMP-deleted car without disciplined premix.
medium
Hard hot-starting / flooding
A warm rotary shut down and restarted briefly can flood and refuse to fire, fouling the spark plugs - a classic rotary trait that worsens as compression drops.
Fix: Follow correct hot-start procedure, fit fresh quality plugs, and treat persistent flooding (with low compression) as a warning of a tired engine.
medium
Differential, clutch and driveline wear
The high-revving turbo drivetrain and spirited use wear clutches, and the LSD and rear diff can whine or wear, especially on modified or track-used cars.
Fix: Inspect clutch and listen for diff noise; rebuild/replace as needed with quality parts.
medium
Rust and aged interior/electrics
Now 25-30+ years old, FDs can show rust in sills, floors and around seals, plus brittle interior plastics, peeling switch coatings and aging electrics.
Fix: Inspect bodywork and underbody carefully; favour dry, well-kept cars and budget for trim/electrical refresh.
high
Modification and abuse damage
FDs are heavily modified by the tuner scene; over-boosted, poorly tuned or single-turbo-converted cars can have stressed or already-damaged engines and dubious workmanship.
Fix: Prefer stock or professionally modified cars with dyno/build records; compression test and inspect tune quality before buying.
