The FD RX-7's 13B-REW twin-turbo rotary engine is inherently prone to apex seal wear and failure. Apex seals are the rotary equivalent of piston rings, and they wear from high temperatures, poor lubrication, and carbon buildup. Seal failure causes low compression, power loss, har… Repairs typically run $3,000-$6,000. Severity: high.
The FD's sequential twin-turbo system relies on 8+ vacuum-controlled solenoids, dozens of small vacuum hoses (the infamous 'rats nest'), check valves, and two actuators to transition between primary and secondary turbo operation around 4,500 RPM. Extreme under-hood heat (often 20… Repairs typically run $400-$6,000. Severity: high.

The FD RX-7's sequential twin-turbo system uses an incredibly complex vacuum hose network to control turbo transition, wastegates, and boost control. The system has dozens of vacuum hoses and solenoids that deteriorate with age, causing boost problems, rough transitions between t… Repairs typically run $60-$3,000. Severity: medium.
A widespread FD complaint is that the car becomes very hard to start after a hot soak (10–30 minutes after shutdown). Aged primary or secondary fuel injectors lose their ability to hold residual fuel pressure and drip into the rotor housings, soaking the spark plugs and flooding… Repairs typically run $300-$1,500. Severity: medium.
The FD3S uses four ignition coils (two leading, two trailing) wired through a long harness that runs across the hot rear of the engine bay. The coils themselves fail from heat soak, and the harness insulation cracks and shorts to ground, causing intermittent or sequential coil fa… Repairs typically run $250-$900. Severity: medium.
