Hey guys ive seen a few posts but no answers, does anyone have the torque spec for these main studs?

Thank you so much i swear i looked through every post for these. Do you know if these came with washers for an rb26?

Not 100% sure but from what I can tell from an old pic & description they didn't come with washers

Okay thank you, only picture i could find was of sr20 ones with washers.
Just curious where did you find picture/torque spec

I got them from GReddy for one of the drift guys & still had the email

To drag up an old thread. I recently stripped an engine I got and it has grex/greddy main and head studs. Anybody know the torque specs for the rb26 grex head studs?

As a guess I would say arp2000 specs should be fine mate if you can’t find solid info on them

If you can't find the actual specs then I'd stick with standard RB26 specs, maybe just a touch higher. Being a stud as opposed to a bolt the actual clamping force will be greater than a bolt at the same torque so at factory spec you're actually at a theoretical higher tightening torque level if that makes sense?
