If you'll use glycos be sure to check edge thickness really good. Some are way off.

And what's the problem with the edges and how can I even check that?
And can anyone comment on the pic of my old bearing? I think that the wear is normal but would like to hear from some people who know more about such things.

I thought Glyco was the only option for 94 bearings. I've never seen any other brand that fits.

Your best bet though is to take pics of all 8 pieces and start a new thread just for feedback on your bearing condition. Put it in the general 944 area, not the turbo-specific one, and it will draw the attention of people who know

I can't tell you much about your pic, except that the 2 lines that run the whole way along the length look strange to me. You should have a read through this - it might help.

Apparently my bearing is typical of 944s although mine is towards the more extreme. Thanks for the mahle link. According to that link, my bearing looks to be suffering from slight oil starvation and possible dirt contamination which makes sense as starvation is what kills the rod bearings on our cars.
Anyone know if running mobil 1 synthetic is not good with the new bearings? Should I start with standard oil and then switch to syn after break in? Is any break in really needed with just new rod bearings? And how about revs during break in?
Also, one weird thing I've noticed is a white/pinkish coating throughout the exhaust, including the spark plugs, O2 sensor, manifolds, crossover pipe, etc. It looks like the standard build up usually seen in these areas except that it is a very pasty white which turns to a pinkish hue and then almost to red in certain areas. And there is what seems like a large amount of build up considering the plugs aren't that old. Plugs are NGK iridium. Anyone ever see this?

You might want to check out Michael Mount's rod bearing mod to allow the use of clevite bearings. No changes to the crank are required but you do need to send him your rods.

Arrrggggggggggg, didn't notice it til now but my downpipe is cracked where it attaches to turbo. Apparently it has been without the support bolt into the block and that caused lots of stress on that flange. I don't think welding is a smart idea since the downpipe is double walled and ceramic lined. Has anyone welded their downpipe?
