ok, so i am almost done with project tird (spelled intentionally that was cause its a mix of a turtle since its taking forever, and a bird because when my car is done its going to fly !!) and i break out the old fsm and start to torque the intake down but its in a Nm spec, and my wrench does nm and lbs, but the readings on my wrench are diff than the manual, like my manual says for instance i think liek 13~`18 nm, and my wrench says 130nm and 180nm, is that the same thing ? i was debating converting the nm to lbs and doing it that way, also for one of my bolts, i replaced it with a stud and a nut , the num 3 to torque down , due to clearance issues with my manifold, should i toruqe it to nut spec which i know is either stronger than bolt (due to how the pressure is applied) or to bolt spec, if this is confusing its because i am typing this kinda fast, and my digital camera fubar

Look at the first few pages of the FSM that explain the measurement icon legends and make sure you're converting from the right base. I think FSM shows both KGM and NM for each nut, can't remember the order though. One's on top and the other underneath IIRC.

I'd torque the stud/nut to the same spec as the FSM says...
