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

29 fl/lbs. in several passes,in sequence shown( when facing the block)

11 9 7 1 3 5
12 10 8 2 4 6
and do 1 and 7 one more time as 13th and 14th.

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

What about the physical studs themselves?

Didn't he say 29 ft/lbs at the top of his post?

 

[ardmore]

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

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.
