Engine: The Rotary Realm
The 13B-REW engine, the beating heart of the RX-7 FD, is a masterpiece of engineering that demands respect and meticulous care. While tales of rotary reliability woes are plentiful, a well-maintained engine can indeed surpass the 100,000-mile mark with grace. The key to longevity lies in rigorous and regular maintenance.
Service History: A Chronicle of Care
A comprehensive service record is your first line of defense in ensuring the rotary engine's vitality. Regular oil changes documented every 3000-5000 miles, with a new oil filter at each interval, are non-negotiable. Given the rotary's design to consume oil, these changes are paramount for health. Query the seller on track use, as rigorous post-track maintenance can speak volumes about the car's care.

- Turbo Inspection: Check for smooth operation of the twin-turbo system. Stiff or brittle vacuum lines should raise flags for potential replacement.
Test Drive: The Moment of Truth
- Idle and Exhaust: A healthy RX-7 should idle around 800rpm. Watch for steam or unusual exhaust emissions, which could indicate compromised coolant seals.
- Coolant Maintenance: Verify annual coolant replacement to protect seals and check for any signs of leaks, a common concern in these vehicles.
Transmission: The Power Pathway
- Clutch and Gearbox: While the FD's clutch is robust, the twin-turbo system's second turbo requires vigilance. Ensure it engages correctly around 4500rpm. Synchromesh wear, particularly from fourth to fifth gear, is a known issue to monitor.
Suspension: The Dance of Dynamics
- Bushings and Alignment: Time and use can wear down suspension components. Check for any modifications that could affect ride quality or wheel alignment. Listen for rear knocking, a sign of potential trouble.
Brakes and Steering: The Control Centers
- Braking System: While adequate for stock conditions, worn brakes are a concern. Ensure the hydraulic assisted steering operates smoothly, free from age-related degradation.
Interior: The Command Center
- Wear and Authenticity: Look for signs of wear in key areas like the steering wheel, gearstick, and seats. Confirm the car's market origin through interior configurations, as UK models differ from JDM imports.
Exterior: The RX-7's Armor
- Modifications and Rust: Exterior mods should be scrutinized for quality. Inspect for rust in common areas, including under the brake lights and around the rear wing. Moisture intrusion from spoiler deletions or wing damage can lead to hidden rust issues.
