    Apparently this engine was not built by people with muscles. 60ft/lbs all the things.

    except for the axle nut haha I had to barrow a TQ wrench for semi truck pinion nuts to torque my axle nuts, and no that's not a joke.

    Looks like the torque rating was taken from the G35M-R and not the A26MX-R which is our transmission/turbo engine setup. They are just a few pages apart in the workshop manual so easy to miss. The right torque should be 151.3 - 161.1 Nm (111.6 - 118.8 ft-lbf)

    Glad I could help, when I was building my engine I kept getting pissed when I couldn't find a spec or if I has to dig forever for one, drove me up a wall

    I can't find the head gasket procedure in the workshop manuals. Do the head bolts call for any lubricant? I would think enine oil but I can't find any info anywhere.

    In my mind knowing if they need lubricated or not is a pretty important part of torqueing! :)-

    Good info. In the past I had to spend most of the time researching torque specs. Then it ends up the torque specs would be hand tight, hand tight + 1 turn, tight but not too tight, normal person tight, and muscle man tight lol.
