Comprehensive parts and service manual for 1989 to 1990 Mazda RX-7 second generation. Covers the unique 13B rotary engine with apex seal procedures twin turbo diagnostics sequential fuel injection suspension geometry and complete system diagrams.
1989 to 1990 Mazda RX-7 Second Generation Service Repair Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The second generation Mazda RX-7, known internally as the FC3S chassis, was produced from 1985 to 1992 with the 1989 to 1990 models representing the Series 4 and early Series 5 updates. The FC RX-7 marked a significant evolution from the original FB generation featuring a more powerful 13B rotary engine, improved suspension geometry, and a more refined interior. The rotary Wankel engine, unique among mass produced automobiles, was a major selling point for this lightweight sports car.
The 13B twin rotor engine displaced 1308 cc (654 cc per rotor) and produced approximately 146 HP in naturally aspirated form with the twin turbo variant delivering up to 180 HP in Japanese specification. The sequential twin turbocharger system was engineered to eliminate turbo lag across the entire power band, providing smooth power delivery.
Mazda was the only manufacturer to persevere with rotary engine technology through the 1980s and 1990s, and the RX-7 remains the most successful rotary powered production car ever built. The FC chassis features fully independent suspension with front double wishbone and rear semi trailing arm layout, providing handling that rivals European sports cars.
