URGENT: another connecting rod bolt torque question
 
I’m getting few conflicting answers from few different reliable sources and trying to figure out which is correct

The motor is a 1980 911sc 3.0

1. Is a picture of the connecting rod bolts sent to me by pelican in their kit

2. Is a picture posted on pelican in a few other threads I’ve been reading

My question is, my bolts say 12.9 clearly but the bulletin does not pertain to my engine year.

Do I still follow the 10.5ft/lbs and then 2 90s?

Your rod bolts are a different size. I would use the torque specification for your engine.

Yes, the tech bulliten is for the 3.2 motor, which has 9mm bolts. The SC has 10mm bolts.

First two shops I talked to locally said 50-55nm, I only second guessed that after seeing the 12.9
