Hi all, so i've got my turbos off and most of the nuts were really loose.
one elbow was held on with 1 nut slightly tight 2 nuts less than finger tight and 2 missing the other wasn't much better.
The manifold bolts where pretty loose as well.
While this made stripping down a lot easier i'd like to get them torqued down correctly.
I've ordered new locking nuts from driftworks.
i've searched but can't find the correct torque.
looking for manifolds and elbows torques?, i did find one thread that sugguested 18-24nm would that be right?

thanks for any help

I had the same problem, I'd re-fitted the turbo's, then about 12 months later all of the nuts came loose.

Stripped it all down again and a friend of mine who's a Rolls Royce technician and builds these RB's for people helped me.
Using a 3/8 drive he did the nuts up as TIGHT as possible having had this problem before. Since then no problems, so whether the torque setting aren't high enough, I don't know, could be the case.

Yes 18-24Nm.

Not a fan of “as tight as possible”......take it from a real engineer who has designed many successful bolted joints.

Tight as possible usually ends up as: "Just a bit m...*SNAP!* "

I bought a Silverline torque wrench for doing a few bits on my GT86, it wasn't hideously expensive like some and does the job, really pleased with it.

cheers guys.. didn't want to do as tight as i could
got everything i need now to fit turbos. just one stubborn stud in the elbow to get out.
and hopefully every nut will stay tight.

24Nm is 17.70 ft-lb I'm old school

My torque wrench doesn't even go that low. So hopefully all will be OK mate.

Ive got a bike torque wrench, the max setting is 24nm lol lucky,
it's only a short wrench and 24nm is about as tight as i can get it with it

just snapped to many things to risk it.
