X25XE

Cavalier and Calibra (not vectra)....its  an earlier version without EGR and air injection plus a different exhaust cam

Would that be the Y25 then?

Nope

C25XE - First verision fitted to Calibra and Cavalier - No EGR and air injection plus differnet exhaust cam (an 'A' from memory). No multiram setup and an average inlet setup.

X25XE - Fitted to Omega, Vectra and Post 95 Calibras. This had EGR and air injection plus multiram. The exception to the rule is the later Calibra which kept the C25Xe inlet setup without multiram.

Y25 - Does not exist, there is the later Y26SE which ahs no air injection or EGR but utilises lower compression ratio and coil per plug ignition to meet emmisions specs. Also has drive by wire throttle and a different exhaust cam (an 'N' cam from memory)
