Cheap Nissan NP300 Cylinder Head

The NP300 Navara was sold in the UK in two main generations: the D22 (produced into the mid-2000s) and the D40 (2005–2015), with the current D23 running from 2016 onwards — these generations do not share cylinder heads, as the engines differ significantly between them. Even within a generation, fitment depends above all on the engine code, which you can find on your V5 or via a VIN check. Always confirm the engine code with the breaker before purchasing, as crossing a generation boundary is very unlikely to work.

This question spans the D40-to-D23 generation boundary (the D40 ran 2005–2015, the D23 from 2016), and the two generations use different engine families, so a direct swap is very unlikely. The engine code is the definitive check — supply your registration or V5 engine code to the breaker so they can match it precisely. Never assume fitment across that 2015–2016 generation boundary without the breaker confirming it against your specific code.

No, the trim level does not affect cylinder head fitment on the NP300 Navara — Acenta and Tekna are specification packages covering interior, infotainment, and cosmetic features, not engine variants. What matters is the engine code, fuel type (diesel or petrol), and whether it is manual or automatic, not the badge on the tailgate. Give the breaker your engine code and they will match the correct head regardless of trim.

The 2.3-litre twin-turbo diesel in the D23 NP300 Navara (2016 onwards) uses the YS23 engine family, but there can be differences in head specification depending on the exact variant and production date. The engine code stamped on the block is your most reliable guide — give this to the breaker rather than relying on displacement alone. Confirm with the breaker against your registration that the specific head they have matches your code, as ancillary and mounting details can vary mid-production.

No — diesel and petrol cylinder heads are fundamentally different in design, combustion chamber shape, and injector provisions, and they are not interchangeable under any circumstances. Make sure you tell the breaker your fuel type as well as your engine code when requesting a quote. This is a basic but critical detail that will prevent a completely wrong part being supplied.

A cylinder head itself is a mechanical component and does not typically require ECU pairing in the way a fuel injector set or engine management unit might, but whether any ancillary sensors or components attached to a second-hand head need calibration is something to confirm with the breaker and your fitting garage. Some variables, such as whether sensors carried over from your original head will be reused, can affect this. Your fitting mechanic is best placed to advise once they have the specific unit in front of them.
