Head Sequence for 1-14: 12 8 4 2 6 10 14



Front

11 7 3 1 5 9 13 1-14==m12x 1.5 15-17==m6x1.0

Tighten to 29N-m (3kg-m)Tighten to 98N-m (10kg-m)Loosen to 0N-m Tighten to 25-34N-m (2.5-3.5kg-m)Tighten to 9.5-10.5kg-m

The r33 manual does have a bottom end section for the rb25, only for rb26. The torque specs may be the same but I'm not sure. LMK if you want it.

Says they're "cylinder head auxillary bolts" I don't know what they are for but don't torque them to the above specs. I don't see any torque specs for them.
