The Mazda RX-7, specifically the Third Generation (FD) chassis, represents a pinnacle of sports car engineering from its production years of 1992-2002. Renowned for its distinctive lightweight chassis, balanced handling, and the iconic 13B-REW twin-turbo rotary engine, this vehicle embodies Mazda's 'Jinba Ittai' philosophy, emphasizing a profound connection between driver and machine. Its aerodynamic styling and exceptional performance, which earned it accolades such as Car and Driver's '10Best' list, positioned it as a formidable competitor in the grand touring and sports car segments against rivals like the Nissan 300ZX and Toyota Supra. This Workshop Service Manual (WSM) in English provides comprehensive guidance for the maintenance, repair, and rebuilding of your Mazda RX-7. It covers all major systems, including the 13B-REW rotary engine, fuel, ignition, cooling, lubrication, exhaust, transmission, drivetrain, suspension, steering, brakes, and electrical systems. Detailed procedures for scheduled maintenance, troubleshooting, component testing, and in-depth engine and transmission overhauls are included. This manual is an essential resource for professional technicians and advanced DIY enthusiasts seeking to preserve the performance and integrity of their RX-7. 🏷️ Basic Information Identification Make: Mazda Model: RX-7 Chassis Code: FD3S Generation: Third Generation (FD) 👋 Introduction Market Position Market Segment: Sports Car, Grand Tourer Key Selling Points: Rotary Engine, Lightweight Chassis, Balanced Handling, Iconic Design Competitive Analysis Primary Competitors: Nissan 300ZX (Z32), Toyota Supra (Mk4), Mitsubishi 3000GT/GTO, Porsche 968, Chevrolet Corvette (C4/C5) Key Features Design Philosophy: Jinba Ittai (Horse and Rider as One), emphasizing driver connection and agility. 📋 Manual Details Coverage Areas Manual Type: Workshop Service Manual (WSM) Language: English Format: PDF Download Intended Audience: Professional Technicians and Advanced DIY Enthusiasts 📖 Manual Coverage Systems Covered Engine: 13B-REW Twin-Turbo Rotary Engine (All Configurations, Maintenance, Troubleshooting, Rebuild) Fuel System: Fuel Injection, Fuel Pump, Injectors, Fuel Pressure Regulator, Emissions Control (including secondary air injection) Ignition System: Ignition Coils, Spark Plugs, ECU Control, Timing Cooling System: Radiator, Water Pump, Thermostat, Fan Control, Intercooler System Lubrication System: Oil Pump, Oil Cooler, Oil Filter, Oil Capacity Specifications Exhaust System: Catalytic Converter, Mufflers, Exhaust Manifolds, O2 Sensors Transmission: R154 5-Speed Manual Transmission (Disassembly, Assembly, Repair, Fluid Specs) Drivetrain: Driveshaft, Differential, Axles, Wheel Bearings Suspension: Front and Rear Suspension Components, Bushings, Shocks/Struts, Springs, Alignment Specifications Steering: Power Steering System, Steering Rack, Tie Rods, Column Brakes: Front and Rear Disc Brakes, ABS System, Brake Lines, Master Cylinder, Rotor and Pad Specifications Electrical System: Battery, Alternator, Starter, Wiring Diagrams, Fuses, Relays Body And Chassis: Body Panels, Doors, Hood, Trunk, Chassis Structure, Corrosion Prevention Interior: Seats, Dashboard, Trim, HVAC Controls, Airbags HVAC: Air Conditioning System, Heater Core, Blower Motor, Refrigerant Type and Capacity Lighting: Headlights, Taillights, Interior Lights, Bulb Types and Specifications Diagnostics: OBD-II Codes, Diagnostic Procedures, Troubleshooting Guides Procedures Included Maintenance: Scheduled Maintenance Intervals, Oil Changes, Filter Replacements, Spark Plug Service, Fluid Checks and Replacements Troubleshooting: Systematic Diagnostic Flows for Common and Complex Issues, Symptom-Based Troubleshooting Repair: Component Removal, Installation, Reassembly, Adjustment Procedures for All Major Systems Rebuild: Detailed Engine Rebuild Procedures (Apex Seals, Rotor Housings, Rotors), Transmission Rebuild Procedures Electrical Diagnostics: Wiring Harness Repair, Sensor Testing, ECU Diagnosis Specifications And Tolerances: Torque Specifications, Gapping Specifications, Clearance Measurements Component Testing: Testing of Sensors, Actuators, Relays, and Electronic Control Units Technical Depth Engine Rebuild: Comprehensive, including apex seal replacement, rotor housing inspection, and port timing adjustments.
