what to torque bolt to?

 

Do you mean the bolts that go from manifold to engine, or manifold to turbo?

 

to engine

 

I dont know exact numbers but most people just get it as tight as they can and a few days later retighten.

 

somewhere around 40 ft lbs i think

 

I want to say it's 37-45 ft*lbs... but It's been a while.

 

Is the factory spec still valid with a greddy cast manifold?

Tighten it till just before it breaks. Can you actaully get a torque wrench on all the bolts anyway? I just tightened the **** out of it and have had no issues.

 

thanks,i just used 40 ft/lb on the ones i could get the torque wrench to and guessed on the others

 

Hand torque them inside to outside and then re-torque them in a couple of days. Only one of mine came loose.

I just tightened mine to PFT spec.
