It would take some double-checking with those who are in the know, but I think that LK9 engine had a "new" (that is, updated) block at the time of introduction as well, and that the entire project was collaborative between Rüsselsheim, Pontiac (city, not brand), and Trollhättan. Maybe the latter did the head.
But that project was going on more than a decade ago. It sounds like Trollhättan was moving to the periphery in the last several years. One could make the case that GM had sucked them dry, but I think the rest of GM would have been able to get by without them anyway. Even though it doesn't always look like it from the consumer POV, lots of smart people work at that company.

Good stuff. Not saying GM isnt full of bright folks. Just figured it may be like the Daimler takeover of Chrysler... Get a few things, suck them dry, then get rid.
I might be way off... But the story was that the Saab 2.0t engines were highly modified variants of the alloy 2.2L engine modified fully by Saab and designed for better fuel economy than the existing super/turbocharged GM equivalents of the time. The main thing was a grabbing of some of the key experience and design aspects (turbo engine design, some controls stuff that they were ahead on as far back as the early 1980s), etc.
Standard means of a large company getting technology...
I have a 9-3, and wish that GM had not dumped saab. But my story is based upon my reading back to 2004. Take it with a grain of salt.
