Re: what grade bolts
 

I've used heat treated steel bolts, as well as grade 5. Grade 5 holds just fine, I never have had problems.

Re: what grade bolts
 

Grade 8 just has to do with the tensile strength of the bolt. The bolts don't need to be strong when mounting a turbo to a manifold. The part that gives people the most difficult is when the bolt and the flange are made out of different materials. Different metals expand and contract at different rates and temperatures. If you have to contrasting metals, they can loosen very quickly.
