lol, a diesel diff looks like a petrol one and NONE of the internal bits interchange....so going on that (and having examined a opel diff from pics) i would say no go.....i could be wrong but until some1 gets a opel diff to compare we are none the wiser....
Quaife in the UK make torsen style centres for the opels and piazza. Note the label in the bottom right corner. I have used this diagram and compared it to the diesel centre I have and everything lines up. So from this information you would conclude that an opel manta and some kadett centres would fit a diesel housing. It would still need someone to fit one and prove it though.
From what I can tell, like Australia, the UK only got the turbo Piazza. Like Australia some of the non-turbo cars snuck in. The diff behind the non-turbo cars is a torque tube style and shares the centre with opels and diesel gemini where as the turbo Piazza has a bigger banjo style diff. A non-turbo Piazza can have a twin cam, G200Z or 2.3l SOHC. The US on the other hand got everything but they called it Isuzu Impulse.
No. Not easily anyway. The carrier in a petrol salisbury diff is longer than the diesel carrier. The early Borg Warner comes close but is too small. If I could find my diesel centre I would post some pics but I think its buried under some Ford crap.
