|---|---|
| Assembly Number | 1J403-00004, quoted for the complete unit and carried with 1J477-53000 in the same listing |
| Cylinder Head | 1G780-03043 and 1J860-03040, bare head listed for this engine and its direct injection and turbocharged builds |
| Injector | 16419-53900 and 16419-53905, listed across the 2.2 and 2.4 litre members of the range |

| Caution - One Name, Two Fuel Systems | The mechanical and common rail builds do not share pumps, injectors or control hardware, so the plate code decides what can be supplied |
| Caution - A Second Badge On The Same Engine | One engine guide states the family is also sold for under the C2.4 designation, so a search by machine model can return the other badge |
| Caution - Ratings From 33.6 To 48.6 kW | 33.6 kW at 2400 rpm, 36 kW at 2600 to 2700 rpm and 44 kW at 2700 rpm all appear on this engine, with 48.6 kW on the common rail turbo build; one capacity carries all of them |
| Caution - A Smaller Relative With Shared Numbers | The 2.2 litre member uses the same bore on a shorter stroke and shares the injector numbers above, so capacity and injector number together still do not identify the engine |
| Caution - Wide And Uneven Price Spread | Units sit mostly between 800 and 5500 per piece, used from 350 to 1280, new around 3290 to 5500, with one heading quoting 2700 to 5500 for two pieces |
| Related Components | Cylinder head 1G780-03043; injector 16419-53900; turbocharger 49131-02090; piston and ring set; liner kit; crankshaft; main and rod bearings; injection pump; water pump; oil pump; overhaul gasket kit |
Two families share the block: mechanical direct injection versions marked M, M-DI and M-DI-T with their emission and OEM suffixes, and common rail versions marked CR, CR-T and CR-TI. Suffix and stage together fix what is inside.
It can. One engine guide states the family is also sold for under the C2.4 designation, so a buyer searching by machine model can be quoted the same unit under a different badge.
Heads are listed as 1G780-03043 and 1J860-03040, injectors as 16419-53900 and 16419-53905, and the turbocharger as TD03 with number 49131-02090, so they identify the range rather than the exact build.
