Used Nissan 350Z Engine

The 350Z was produced from 2003 to 2009 and used variants of the VQ35DE and later VQ35HR engine codes across that run, with the HR unit replacing the DE around 2006 — these two codes are not a straight swap, so you need to confirm which code your car has before searching for a donor engine. Check your V5 or run a VIN check to get the exact engine code, as that is the single most reliable detail to give a breaker. Whether ancillary brackets, engine mounts, or loom connections differ between specific production years is something you should confirm with the breaker against your registration.

The 2003–2005 cars used the VQ35DE, while from around 2006 onwards Nissan moved to the revised VQ35HR, and these are different engine families with different internal architecture, so this crosses a significant engineering boundary. Always tell the breaker your engine code — found on your V5 or via a VIN check — rather than relying on year alone, because the year-to-code cutover may not fall exactly where you expect on every car. A breaker can confirm whether the specific donor unit matches your car's code and whether any ancillary or mounting changes need accounting for.

For the engine itself, trim level does not affect fitment — a VQ35DE is a VQ35HR regardless of whether it came from a GT, Touring, or GT4 car. What matters is the engine code, fuel type, and gearbox type (the 350Z was available with a six-speed manual or a five-speed automatic, and these configurations can affect ancillary components). You may find minor cosmetic or bracket differences between donor cars, but confirm any ancillary specifics with the breaker against your registration rather than assuming a like-for-like swap on every detail.

Yes, it is worth flagging your gearbox type to the breaker, because manual and automatic variants of the 350Z can have differences in ancillary components and sensors associated with the engine that affect compatibility. The core long engine with the correct code — VQ35DE or VQ35HR — is the primary match, but telling the breaker whether your car is a six-speed manual or five-speed automatic helps them supply the right ancillaries. Never assume a bare engine and all its attached components will be identical across both gearbox types without checking.

The engine code is the most important detail you can provide, and the easiest way to find it is from your V5 logbook or by running a VIN check through a reputable UK service. For the 350Z you are looking for either VQ35DE (broadly the earlier cars up to around 2006) or VQ35HR (broadly the later cars from around 2006 to 2009), though the exact changeover point on your specific vehicle is best confirmed by the code itself rather than the year. Give that code to the breaker at Findapart so they can match a like-for-like donor unit accurately.

Provided both cars share the same engine code — for example both are VQ35HR — this is the right starting point for a compatible match, and the engine code matters far more than the model year within the same code family. However, whether ancillary components, engine mounts, or ECU pairing present any complications across that period is something you must confirm with the breaker against your specific registration, as mid-production changes can occur without a clear year boundary. ECU and immobiliser coding in particular should always be discussed with the breaker before purchase.
