Here is the pictures of the engine..
And here is the engine number 10299012001369
Decoding this number leads to a regular 2.5 16V, maybe an AMG power pack maybe not...but for sure not an evo1 or evo2
codes:
102983 = 2.3-16
102990 = 2.5-16
102991 = Evolution
102992 = Evolution 2
102990 10 0000030 = MG manuel getriebe (gearbox)
102990 12 0000030 = AG auto getriebe (gearbox)

so it was a 2.5 16V with an auto Gearbox
