There is a standard torque rating for different thickness, thread pitch, and alloy/hardness grade of bolts. I don't know what those ones are without digging out a turbo in a box but look at the diagram posted above, there is no locking hardware on them - just a strap washer under them.

For example if they are common 8mmx1.25 thread pitch grade 8.8 bolts the torque would be about 18 ft lbs and it can be a little more than that without any problem. I don't know if turbo rebuilders put some type of high temp loctite on those bolt threads but you should be able to find out.
