Frequently Asked Questions
Does this manual cover apex seal replacement on the 12A engine?
Yes. Apex seal wear is the most common rotary engine concern on first-generation RX-7s, and the manual provides complete step-by-step teardown, inspection tolerances, and reassembly procedures for both the 12A and 13B-RESI engines, including rotor housing inspection and eccentric shaft measurement specs.
Is the Japanese-market Savanna RX-7 covered alongside the US-spec car?
Yes. The manual documents both the North American FB-chassis RX-7 and the Japanese-domestic Savanna RX-7, which share the same SA22C platform. Specification differences between markets are noted where applicable.
Are complete wiring diagrams included for all model years?
Full electrical schematics are included for every year from 1978 through 1985, covering ignition, charging, lighting, instrumentation, and emissions-related sensors. Color-coded wire identification and connector locations are documented to simplify diagnosis on aging wiring harnesses common on these vehicles.
What format is the manual?
The manual is a PDF file delivered via instant download after purchase. It is fully searchable and compatible with Windows, Mac, Linux, iOS, and Android devices. Pages can be printed individually or in sections, and the file may be saved to multiple devices for permanent offline access.
