yes, that's why I'm giving it a shot first. But, given the location, heat cycles, vibration and pressure, I'd prefer to have a plan in place should the stud fail to hold.

New manifold, no. This stud passes through the manifold and threads into the turbo.

Helicoil, great! Which one? Never used one before and a quick look through the product list I see 1084-10CN150 are the "common" 304 stainless rated up to 800 degrees F; and 1084-10TN150 are the INCONEL X750 rated up to 1000 degrees F.

Will the 304 stainless be sufficient or do I need to track down the INCONEL X750?
