last August i purchased a spare engine for my VIS with 52k. Out of curiosty I thought I amy need the engine number if i decided to resell the engine as the engine in the coupe is fine, and just wants to eat miles.
182B7000 is the type of engine, and the car it was destined for (i.e. originally fitted). This is the type, not the engine number, which should be underneath it.
