What grade bolt, washers, nut for turbo exhaust housing to turbo manifold? I was thinking about using some stianless steel bolts but I don't they they will hold up. Should I go with a grade 8 bolt or is there something better I can use to prevent rusting?

I just use whatever manifold bolts NAPA or the dealer sells. Not sure what grade they are.

grade 8 will work fine, I have not seen many bolts not rust once they get heated a few times. The last ones I got from Advance with nuts and locking washers. Check the flanges ensure they are true if not hit them with a belt sander. should take no more than a little spray copper to seal them.

I tried using grade 5 stainless before but the bolts didn't hold up when I took them out. The nice thing about the stainless bolts were that they kept their finish and didn't rust.

I use grade 8 stainless. They look alot better and i never have a problem removing and reinstalling them.

Stainless is fine, just use alittle anti sieze on them. Grade 8 is overkill.

Where can I find grade 8 stainless? I've tried ACE's hardware and they don't carry it.

I would like to have the extra security if possible. I just don't know where to find grade 8 stainless.

Are you referring to a Bumax 88 stainless bolt.

I don’t recall seeing a grade 8 stainless bolt.

I have only seen grade 2,5 and 8 numbering
used on steel bolts.

I guess i should have clarified i use Aircraft grade stainless bolts. With a tensile strength equal to a grade 8 or stronger (but i get them at a good discount).

I can understand wanting some overkill but I have used standard stainless bolts from ACE hardware on everything automotive we do and never had a problem. The fastner doesnt really need to be strong.

I snapped 2 stainless steel bolts trying to untread them to take my turbo out.

You dont need more strength, you need anti sieze.

Stainless into mild steel without antisieze is not good. Use the hi temp antisieze.. IE:

Spring type lock washers are useless after the first hit w/ heat..
