The Honda S660's sole S07A 660cc turbo petrol engine is generally robust but known for turbo wastegate rattle, timing chain tensioner wear, and oil consumption on high-mileage JDM imports. Every rebuilt S07A engine supplied through EngineMarket includes upgraded internal components designed to address the original failure point - plus a minimum 12-month...
Turbo Wastegate Rattle
Most affected vehicles
Honda S660 α, β, Modulo X, Modulo X Version Z, Concept Edition (2015-2022, S07A)
Failure mileage range
40,000-70,000 miles
Typical failure window
Root cause
The S07A's small turbocharger wastegate actuator can develop play over time, causing rattling noises and inconsistent boost pressure, particularly on JDM imports subjected to UK fuel quality variations.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Wastegate Actuator Replacement | £850 - £1,400 | £550 - £950 | Replace wastegate actuator and linkage, recalibrate boost control | Viable if caught early before turbo damage; 20k-40k mile extension |
| Intermediate - Turbo Rebuild Kit | £1,450 - £2,200 | £950 - £1,550 | Full turbocharger rebuild with new wastegate, bearings, seals | Addresses root cause; suitable for moderate wear scenarios |
| Full Replacement - Rebuilt S07A Engine | £3,850 - £5,200 | £2,850 - £3,950 | Complete rebuilt S07A with upgraded turbo components, bench-tested, supply & fit available | Comprehensive solution; recommended for high-mileage or catastrophic turbo failure |
Our recommendation
For S07A wastegate rattle under 60k miles, a specialist turbo rebuild often offers the best value. If the engine has high mileage or shows additional wear signs, a full rebuilt S07A with upgraded turbo components provides longer-term peace of mind for your JDM import.
