Turbo Studs! Which ones to use?

[Matt01]

Hey Everyone.

I used Napa cheapo studs when i changed my manifold, and 1 of them has broken off inside, the other ones have loosened up.

What studs/bolts do you guys use on the turbo?

thanks

From manifold to turbo, or turbo to wastegate, or wastegate to downpipe?

Mostly, I use Saab parts.

SS studs, and double nuts.
Cleat put together kits long ago, been using them ever since. Get the GOOD Anti-seize.

Its really the turbo to manifold i have problems.

I have seen without reference to it specifically, people using cummins studs.

After looking, the last time I did this (in '12) I used hardware from ATP Turbo. Been five and a half years, so far so good:



Using the right nuts is just as important as the right studs - they need to stay put but still be able to be removed.

Nice! what coating is on the manifold? and did it hold up?

[thesameguy]

Manifold was ported, then ceramic coated in & out. It was done by these guys:

So far, so good.

Those nuts look to be copper. Correct?

[thesameguy]

Copper coated, yes. Small locking head copper coated nuts. They stay put but come off when they should.

They are not cheap but well worth it.
