I've heard that some people have been having issues with the studs on their FM turbo manifolds backing out. This has sometimes necessitated track cars to have to have their manifold nuts retorqued after each session during track days. There have even also been reports of stud failure because of the repeated retorquing of the nuts. So here's my proposed solution...
My solution is threefold:
-First, the size of the manifold studs were upgraded from M8 to M10.
-Second, nuts that are prepped to be safety wired in place will be used so that they can't back off. Each nut will be safety wired to TWO other nuts on the manifold.
-Third, setscrew holes were drilled and tapped into the turbo manifold. Setscrews are then put in place which screw into the manifold's M10 studs, locking them in place and preventing them from backing out.
Other typical hardware is also used (ie the special lockwashers) as are found on other installs.
Here's a pic. It's just hand tightened, not safety wired, and the turbo orifaces are still taped...but you should get the idea:
I'm open to any opinions/suggestions/criticism on this solution. Thanks!
