What grade stud is everyone using? I pulled the turbo off my car after 2500 miles, and the studs BEGI supplied with their manifold aren't holding up. One backed out and one broke with almost no effort. I'm going to replace all 4, but I want to hear what everyone else is using.

 

Home depot nuts. The shiny ones. I retightened some of them a few times after installing them, but they have been solid for a couple of years straight now.

 

The shiny ones. You kill me. Like the Grade 8 gold-ish color?
