Nissan from 1988 to 2024: why the same engine capacity doesn't mean the same part, depending on the model and year

The most common pitfall with Nissan is precisely this: a 1.5 dCi can come with a K9K 276, K9K 700, K9K 608, K9K 629, K9K 646 or K9K 896 block depending on the power output (65, 82, 90 or 110 hp), the year of manufacture and the model — the Qashqai, Juke, Micra, Note and Almera do not necessarily share the same engine code even at the same power output. Equally, the 2.5 dCi covers both YD25DDTi blocks (Navara, X-Trail, Pathfinder) and G9U gearboxes (NV400, Primastar, Cabstar), which have nothing in common mechanically. Before placing any order, the engine code stamped on the block or gearbox is the only reliable reference.

Four part families, each with its own identification logic

The Nissan range offered by EDEN BOITES is built around four families: engines, gearboxes, turbos and transfer cases. Reconditioned engines and reconditioned gearboxes each account for close to half the catalogue, with a strong concentration on the Qashqai (all generations), the NV400 and Primastar on the light commercial side, and the X-Trail and Juke on the SUV side. Turbos cover mainly the K9K, M9T, R9M and YD25DDTi families, with new and reconditioned references available depending on the engine. The transfer case covers a narrower range — checking compatibility model by model is essential.

On the diesel side, three major block families structure the range: the K9K (1.5 dCi, found across city cars and compact crossovers), the M9T / M9R / R9M (2.3 dCi and 2.0 dCi, dominant in the NV400, Primastar and post-2013 X-Trail light commercials), and the YD25DDTi / G9U (2.5 dCi, Navara and larger light commercials). The ZD30 and RD28 engines relate to older vehicles — Patrol, Terrano, Cabstar — with a production range going back to 1988. On the petrol side, the MR16DDT (1.6 DIG-T, Juke) and HR12DDT / HRA2DDT (1.2 DIG-T, Micra, Note) codes are the most widely represented.

Key points to watch depending on use and segment

On the NV400, Primastar and Cabstar light commercials, the gearbox and engine often share their architecture with Renault or Opel vehicles of the same generation: the same M9T or G9U code can appear across several brands, which can sometimes make cross-referencing easier. On the Navara, the YD25DDTi evolved in power output (110, 122, 136, 144, 171, 174 and 190 hp) over a long period: both the year of first registration and the power level are needed to identify the correct part. For the Qashqai, the switch between the 1.5 dCi 110 hp (K9K 410, 636, 646, 666, 896) and the earlier sub-90 hp variants (K9K 608, 629) is the most common identification point to get right.
