X20dth Vectra engine is a different engine to the Y22dth fitted to the Omega unfortunately.
I believe you are limited to Omega and Fronterra as sources for the Y22dth
I can back this up as the crank went on my 03 plate tail end of last year. These engines are hard to get and even if you get a frontera engine you still have to change a few parts. If its of any help to you i have some pistons with rods here for a 2.2 dti but this only helps if your bottom end has no large holes in the side, also if you have to go down the road of getting a new bottom end then when you come to getting the head gasket a 2.0 dti as it's all down to the amount of notches in the edge and it's less money than a 2.2 for some reason. Also there is a vauxhall breaker in the midlands who i got an engine from and it had to go back because they hacked it out of the car and then dropped it so stay well away from them as it was the only engine they had.
