FD turbo to downpipe nuts coming loose
Perhaps a silly question. I'm running stock twins on my racing FD. All of the fasteners (studs and nuts) and gaskets are OEM from Mazda. I'm having a tough time keeping the nuts holding the downpipe to the turbo tight. Any suggestions? Thanks in advance.

Gracer-7 yes, I have the yellow FD. As for EGT's I'm not sure as I don't have thermocouples up there. I don't think things are too hot as my tune is very conservative and I'm only running 12psi.
I do start off with the specified torque, but that only seems to last a while. I'm trying to avoid re-torqung between sessions on the hot turbos.
I'm using the stock nuts which are pretty tall so I don't think I can double nut them.
Do people use nuts from other manufactures? I know the BMW locking nuts are nice.

Don't use Nylocs, don't bother with Loctite. Double nutting helps -- you can get a thinner nut for the second one. I've seen Nordlocks in other high vibration locations used very effectively.

there is a little bar thing on the s4 t2's that goes in place of the washer, and you bend the tabs up and it physically locks the nuts down....
