Do you have the serial number of the engine? I only have spec's based on the engine serial number.

If this is a 5EK serial number, use these spec's,

Lubricate the bolt threads and the seating faces of the caps with 4C-5593 Anti-Seize Compound .
Tighten the connecting rod bolts.
Torque for bolts ... 90 ± 9 N·m (66 ± 7 lb ft)

Put a mark on each bolt and each cap.
Tighten each bolt from the mark to angle ... 90 ± 5 degrees (1/4 turn)
