Found this page...does 47-62 ft/lbs on the third turn sound right?

For a standard bolt - 43 lbs is where it should end up if I remember correctly. The turbo bolts go up to about 60....
Good luck with it - hope you are running again in no time.

Nissan specs L18 and L20B are 47-60 ft lb. The bolts are reusable.

Torque sequence:

R A D
7....8
3....4
1....2
5....6
9...10

Use that sequence and torque all to 20, then 40, then 60. Done.
Dry gasket no coatings

Looks like I got it correctly, everything is lining up and no threads were damaged during torquing
