Used Nissan Primera Engine

The Primera ran as the P11 generation from 1996 to 2002 and the P12 generation from 2002 to 2008, and these are fundamentally different platforms with different engine families, so a direct swap across that generational boundary is very unlikely to be straightforward. The engine code on your V5 is the key detail — share it with the breaker, who can confirm whether any crossover is feasible for your specific application. Never assume a P11 unit will drop straight into a P12 without expert confirmation.

Both years sit within the P12 generation (2002–2008), so you are working within the same platform, which is a good starting point. Engine code compatibility is still the deciding factor — the P12 used several different units including 1.6, 1.8, and 2.0 petrol engines alongside a 2.2 diesel, and you need matching codes rather than just matching years. Give the breaker your exact engine code from the V5 and they can confirm whether a 2004 donor unit suits your 2006 car.

For engine fitment, trim level makes no difference — the SE, SVE, and Touring Sport are all built around the same engine families within the P12 generation, so the trim badge on the donor car is irrelevant. What matters is that the engine code matches your own, along with fuel type and gearbox type (manual or automatic). Bear in mind that ancillary components such as brackets or mounts may differ between donor cars, so confirm those details with the breaker against your registration.

The P11 received a facelift in 1999, and while both pre- and post-facelift cars share the same generation, there can be mid-production changes to ancillary components and mountings that affect a straight swap. The engine code is your primary guide — if the codes match, the core unit is the same, but confirm with the breaker whether any bracket or mounting differences apply to your specific registration. Routing this through a breaker who can check both the donor and recipient against their records is the safest approach.

Gearbox type is a key fitment factor alongside the engine code — a diesel engine sourced from a manual car will not bring the correct bellhousing or ancillary setup for an automatic transmission without additional work. You need to make sure the donor engine came from a car with the same fuel type and the same gearbox configuration as yours. Tell the breaker both your engine code and your gearbox type so they can source a compatible unit from the outset.

The engine code is the single most useful piece of information you can supply — it overrides year, trim, and body style as the primary identifier for a compatible replacement engine. You can find it on your V5 registration document or via a VIN check, and it will typically be a short alphanumeric code such as QG16, QG18, SR20, or YD22 depending on your model. Give this code to the breaker along with your fuel type and gearbox type, and they can cross-reference donor stock accurately.
