88,000 miles · asking $32,000 · 1.3L 13B-REW twin-turbo rotary
7 known failure points for this generation · cost data pending verification
The FD is a light, sublime-handling twin-turbo rotary sports car that rewards you with one of the best chassis ever built and punishes you with a fragile, heat-soaked engine bay. Ownership money goes into apex seals, the labyrinth of vacuum lines, cooling, and the notoriously fussy sequential twin-turbo system.
AI-drafted profile
This failure-mode list was drafted by AI and cross-checked against this car’s real NHTSA complaint data. It has not yet been verified by our mechanics or owners, and it deliberately shows no cost figures: we never publish a dollar amount we can’t source. Own one? Your cost submissions below are what turn this into a verified teardown.
What you’ll notice: Low compression, hard hot starts, loss of power, or refusal to start at all.
The 13B-REW runs hot and the apex seals wear or fail, especially on neglected, overboosted, or oil-starved engines. Most FDs on the road today have had or will need a rebuild.
Typical window: 60k-120k miles

What you’ll notice: Erratic boost, check engine light, poor idle, turbos not transitioning to sequential mode.
The sequential twin-turbo relies on a dense web of small rubber vacuum lines that harden and crack with heat and age. A single failed line throws the whole boost control off.

What you’ll notice: Rising temps in traffic or on track, coolant loss, warped components.
The engine bay is cramped and heat-dense, and the stock cooling setup barely keeps up. Overheating accelerates apex seal death, so a healthy cooling system is critical.

What you’ll notice: Boost spikes, flutter, second turbo not kicking in, or fluctuating boost gauge.
The complex OEM sequential twin-turbo system has many actuators and control valves that seize or leak with age. Many owners convert to single turbo to escape it.
Typical window: 50k-100k miles

What you’ll notice: Rough running, lean conditions, hard starting, fuel smell.
Old fuel lines, pumps, and the secondary injectors degrade, and a lean condition on a rotary quickly kills apex seals. Reflected in the high fuel-system and gasoline complaint counts.

What you’ll notice: Intermittent gauges, no-start, failed sensors, dash warning lights.
Heat and age take a toll on connectors, grounds, and sensors packed into a hot bay. Common enough to show up prominently in owner complaints.

What you’ll notice: Corrosion in rockers, floors, subframe, or evidence of hard use.
These were driven hard, modified, and often poorly repaired. Structure complaints and decades of enthusiast abuse make chassis integrity a real gamble.

EQUIPMENT DESCRIPTION: MAZDA SPEED RESINOUS HOODS, DESIGNED AND SOLD AS ACCESSORY PARTS FOR MODEL YEAR 1992-1995 RX7 VEHICLES, MANUFACTURED BETWEEN JUNE 1, 1997, THROUGH SEPTEMBER 19, 2000.
THE RADIATOR CAP PRESSURE RELIEF VALVE RELEASE PRESSURE IS SET TOO HIGH. THIS CAN CAUSE THE COOLANT TO REACH TEMPERATURES THAT EXCEED THE THERMAL DESIGN LIMITS OF SOME COMPONENTS OF THE COOLANT SYSTEM. SHOULD THIS OCCUR, ENGINE COOLANT CAN LEAK COLLECT ON TOP OF THE ENGINE.
OIL MIST CONTAINED IN THE ENGINE INTAKE AIR CAN COLLECT OVER TIME IN THE BRAKE VACUUM CHECK VALVE PREVENTING THE CHECK VALVE FROM OPENING AT THE SPECIFIED PRESSURE REDUCING POWER ASSIST TO THE BRAKES.
RESIDUAL ENGINE HEAT CAN CAUSE PREMATURE DETERIORATION OF THE FUEL HOSE CAUSING THE HOSE TO LEAK. ALSO, REMOVING AND REINSTALLING THE DETERIORATED FUEL HOSES INCREASES THE LIKELIHOOD OF A LEAK.
