My knowlege of these cars are limmitted, other than my mother had one of those lilac ones when i was a kid

Now my car has an engine number : KAR 11 4 02 and i can't for the life of me find any information as to what it originally came from.
I know its not the original to my car as i have found an old bill saying that the engine was changed in 1999.
is there any way I can find out as google searching has drawn a blank?
