Give Claude, ChatGPT, and any other AI assistant a real knowledgebase for the Mazda RX-7 FD3S. Factory service procedures, tuning references, and community build wisdom — not a generic guess.
Connect once, then ask anything — we do all of the research.
Add rx7db as an MCP server in Claude Code or any MCP client using your own Anthropic API key.
Describe your symptom, tuning question, build goal, or part you need — in plain language, with your car's mods if you like.
An internal research agent works the factory manual, tuning references, and current sources, and cites the diagrams that matter.
A collection of authoritative sources of information on the RX7 FD, plus real-time access to the latest community discussions.
Diagnose a symptom or malfunction and walk through the fix.
Overheating, temperature swings, and coolant loss — diagnosed before the engine pays for it.
Trace circuits, pinouts, and wire colors — with the actual diagram images.
Trace the vacuum "rat's nest", test solenoids and actuators, diagnose the sequential turbos — with routing diagrams.
Parts, tools, torques, and procedure for a job you're about to do.
AFR targets, timing, ECU settings, and tuning symptoms.
Airflow and WHP math for turbo and boost combinations.
Plan a modification sequence toward a target power level.
Check wheel offsets, tire sizes, and suspension, fender, and brake clearance.
Locate OEM or aftermarket parts, with live stock lookups.
Anything else — factory specs, maintenance, how systems work.
When a wiring answer needs a diagram, you get the actual factory scan.
"My fuel pump isn't priming — where's the FPR relay in the harness?"
The wiring tool traces the circuit through the factory diagram and returns the relevant page, so you're looking at the real harness instead of a text description of it.
