Do you guys know the cylinder head bolt torque specs of a KA24de engine from a nissan 240sx coupe 1991 model? Thank you very much!

*Tightening procedures:

a.tighten all bolts to 29 N*m (22 ft-lb)

b.tighten all bolts to 79 N*m (59 ft-lb)

c.loosen all bolts completely

d.tighten all bolts to 25 to 34 N*m (18 to 25 ft-lb)

e.turn all bolts 86 to 91 degrees clockwise, or if an angle wrench is not available, tighten bolts to 75 to 84 N*m (55 to 62 ft-lb)

Also, its on page EM-17 of your FSM.

Also, you need to tighten them in a certain order....

Thank you very much Jerome! Its for my friend's car. He pulled down his cylinder head (due to overheating problem) and he doesn't know the torque. He already knows the tightening sequence. Thanks again.
