Default Turbocharger torque specs

I could not find the torque specifications in the manual, someone help me out:

-Oil feed line to turbocharger (two M8 hex bolts)

-Turbocharger mounting bolts ( two M8 allen bolts)

I am going to go for 14lbs on them (manual says all other M8 bolts 14lbs-15lbs)

I don't want to over torque the bolts and crush/break those two o-rings (top and bottom turbo oil seals).

Turbocharger mounting bolts will flex alot more since they're so long. Be careful with those. But I would be solid and confident at 14lbs.

Just a little technical detail to relieve your O-ring anxiety
You should never be able to crush a properly sized O-ring by “over-tightening” a joint, since their (circular) cross sectional area should always be slightly less than the (rectangular) cross sectional area of the groove they are in.

Now stripping the inside hex in the long turbo Allen bolts is another (ugly) matter
