Buy-risk rundown
| Issue | Symptom | How to check | Typical cost (as of Nov 2026) |
|---|---|---|---|
| Apex / side seal wear (low compression) | Hard hot starts, rough idle, power loss | Warm compression test — look for ~100 psi/face and tight variance; low ~80–85 psi suggests rebuild | Rebuild cost not yet verified on this page; budget like an RX-8 job or higher [1][2] |
| Cooling system / overheat history | Steam, coolant loss, warped housings | Pressure test; inspect hoses and radiator | Not yet verified [1][3] |
| Rust (arches, sills, rear boxes, spare well, hatch drains) | Bubbling paint, clogged drains | Probe arches, sills, hatch channels, spoiler holes | Structural rust can erase the car [1][4] |
| Vacuum / turbo control complexity | Boost spikes or lag; check-engine lights | Boost test; inspect vacuum lines | Not yet verified [3] |
| Heavy undocumented mods | Bridgeports, big singles, no paperwork | Demand dyno sheets and invoices | Mystery builds are projects, not bargains [2] |

Notes
- US FD years are essentially 1993–95; later JDM cars are a different import story.
- Mineral high-zinc oil and frequent top-ups are part of healthy rotary life [1][2].
