Almost Finished

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

Only because you can overtorque with lube, but it should give more consistant results. There's separate torque charts available for bolts that are molybdenum disulphide coated, and the recommended torque is a fair bit lower than for non coated bolts. I'll see if I can find the two for comparison.

Reverend HighTower :w00t:no grease on wheel nuts and studs:w00t:
Agreed, and make sure the threads are clean, otherwise you could undertorque the studs.
Any substance or material that is in contact with the underhead bearing surface of the fastener or the mating threads, must be taken into account when selecting the torque value. As there's no data (as far as I know) for the coefficient of friction for copper greased studs/nuts, it's safest to use the manufacturers recommended torque value which is only based on non lubricated studs/nuts.
Using copper grease could cause over tensioning of the stud leading to ductile fracture or loss of tensile strength.:thumbdown:
LUBRICANT OR PLATING - TORQUE CHANGES
Oil - Reduce torque 15% to 25%
Dry Film (Teflon or moly based) - Reduce torque 50%
Dry Wax (Cetyl alcohol) - Reduce torque 50%
Chrome plating - No change
Cadmium plating - Reduce torque 25%
Zinc plating - Reduce torque 15%
