GEMS is the engine management system. Bosh is the later D2 /Range Rover P38 system. 14cux is the earlier (pre OBD2) system.

Gems was engine management system that was used after 14cux and before Bosch
96 is likely noted to explain that it is fuel injected, as 94 & 95 d1 was sporting a dizzy

GEMS engine will have a big black intake sitting above and between the cylinder banks.

The Bosch engine does not.

Gems has aluminum plenum, Bosch is plastic, its noticable

Gems will say 4.0 or 4.6 on plenum
