For a 1993 Toyota Paseo with a 1.5L engine, the torque specifications for the main bearings are typically around 50 ft-lbs (68 Nm) for the main bearing cap bolts, while the rod bearings usually require a torque of approximately 40 ft-lbs (54 Nm) for the connecting rod bolts. It's essential to follow the proper torque sequence and use a torque wrench for accuracy. Always refer to a service manual for the most precise and vehicle-specific information.
