I just bought some new studs for my exhaust manifold, and after searching, I couldn't find any torque specs for how tight they should go into the manifold.

Does anyone have that number?

Also, how tight should the nuts be?

Thanks

That looks like how to tighten down the manifold. I appreciate that.

What about the physical studs themselves?

nowhere in the FSM say anything about that, I think it work like the head studs, don't over tighten it when you torqued down the manifold it'll tighten it together.

Hey bud, I just put mine in until they stopped turning and went about a 1/8 turn more. No issues after a few years. As for the nuts that tq the header down, I used a sequence known as "tight as a motherfucker" and no leaks or issues there either

Didn't he say 29 ft/lbs at the top of his post?
Oh thanks... I missed that when I read the sentence right below it. :1poke:

Awesome! In the past I've used the "tight as a motherfucker" method, but I've been taking my time on this build, so if there is a quote "right way", I might as well do it.

I'm working on making a basic picture tutorial for installing a single turbo kit on a 2jz-gte, and I just don't want to tell someone the wrong information.

If you're installing a single turbo kit, you're going to have problems accessing the nuts if you're running a tubular manifold.

I tightened all the nuts in FSM sequence and in stages but I used slither's "tight as a motherfucker" approach on the nuts I couldn't get a torque wrench on. I properly torqued the nuts I could access with a torque wrench.

The technical term for tightening the nuts is RFT, (really Fucking Tight). Other than that this is spot on.
