Datsun 280ZX (S130) Common Problems & Reliability
The Datsun 280ZX (S130) arrived in British showrooms in 1979 as the grand-touring successor to the 240Z and 260Z, badged with both the Datsun and Nissan emblems at the start of the marque's UK changeover. It kept the torquey 2.8-litre L-series straight-six but traded the S30's raw edge for a plusher interior, better sound insulation and independent suspension all round; from 1981 a facelift brought revised bumpers, lights and hood plus the L28ET turbo. Only a few hundred were officially imported by Nissan's UK dealers and today barely fifty are thought roadworthy, so honest examples are scarce. As with every classic Datsun, rust is the boss fight: sills, frame rails, floor pans and the hatch all rot from the inside out. Turbo and ECCS fuel-injection examples add fuel-pump, airflow-meter and turbocharger concerns. Buy the best chassis you can afford and treat this as an affordable, characterful classic GT rather than a sharp sports car.

Most Common Datsun 280ZX (S130) Faults & Repair Costs
Structural corrosion (sills, frame rails and floor pans)
All 1979-83 280ZXs are S130 unibodies with minimal factory rustproofing, and UK examples have spent decades on salted roads. Corrosion starts inside box sections and shows at the lower sill seams, front and rear frame rails, floor pans, the battery tray and around the hatch; left unchecked it becomes structural and MOT-failable. Because few panels are reproduced, major rust repairs are expensive and often the economic write-off point for these cars.
Bubbling paint along sill seams and wheel-arch edges, Soft or holed floor pans beneath the carpets, Flaking or scale on the front frame rails behind the front wheels, MOT failure or advisory for structural corrosion, Water entering through a leaking rear-hatch seal
- Run a magnet along the sills, arches and door bottoms to detect filler patches
- Lift the carpets and inspect the floor pans, seat-boxes and battery tray for soft metal
- Look behind the front wheels at the frame rails and front crossmember mounting points
- Check the rear hatch rubber and look for rust bubbles inside the hatch
- Review the MOT history for repeated corrosion advisories
ECCS fuel-pump and turbo-model quirks (1981-83 L28ET Turbo)
The 1981 facelift added the L28ET turbo with Nissan's ECCS electronic fuel control. ECCS-governed fuel-pump relays and modulators can fail, causing cranking without starting or stalling that clears when the ignition is reset, and the pump primes for only a few seconds with the ignition on. The earliest 1981 turbo was automatic-only with an unusual crank-trigger arrangement, so model-year identification matters. Turbochargers neglected on old oil lines lose boost and can destroy bearings, making repairs expensive relative to the car's value.
Engine cranks but will not fire, or stalls and will not restart, No audible fuel-pump prime when the ignition is switched on, Boost slow to build or the gauge failing to reach the red zone on full throttle, Hesitation or lost power above 4,000 rpm on turbo models
- Switch the ignition on and listen for the in-tank fuel pump priming for several seconds
- On 1981-83 turbo cars, check whether the ECCS fuel-pump relay and modulator click and hold
- Confirm the model year, since 1981 turbos were automatic-only with an unusual crank-trigger arrangement
- Test-drive on boost and note any hesitation or lost power
Timing chain stretch and tensioner wear (L28E / L28ET)
The S130 280ZX's L28E inline-six (and the L28ET turbo) uses a single-row timing chain with a tensioner and slipper. After 40-plus years the chain stretches and the tensioner foot wears, so cam timing retards and the chain can slap against the front cover: owners report poor low-speed power, a rough idle and a metallic rattle at cold start. A collapsed tensioner lets the chain slacken or jump a tooth, destroying cam timing and risking expensive internal engine damage on these low-value classics. A full timing chain and tensioner kit is the fix, but labour to reach the front of the long straight-six dominates the UK bill.
Metallic rattle or slap from the front of the engine at cold start, Poor low-speed power and a rough idle (retarded cam timing), Persistent ticking from the timing cover once the engine is warm, Engine cranks but will not start if the chain has jumped a tooth
- Listen at the front of the engine from a cold start for chain rattle or slap
- With the timing cover off, check the cam-sprocket alignment marks to confirm timing has not retarded
- Inspect the tensioner slipper foot for wear and confirm the tensioner holds the chain tight
- Ask whether the chain and tensioner have ever been renewed; budget for a full timing kit if not
Buying a used Datsun 280ZX (S130)? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
