Only on the studs that I didnt use Rebond on when they were put in the manifold. The one that I did - because it came out at the time - is tight.
So, to finalize conclusions I am going to Resbond them all with stainless studs and report back.

Ive had my lugs come loose after I fooled around doing some burnouts, I was leaving and I heard a clunking 2 were falling off...and i did torque them to 100lbs! Had my waterpump bolts back out which were lock-tighted, and i just pulled out my motor last week because it sounded like a spring/lifter collapsed, but it was my cam gear bolt backed out a bit and my gear was sloppy so it created a oval shape inside the gear where the camshaft pinion goes in, so it caused a ticking noise. The guy who built my motor fixed it all for free, im only upset because i had to pull out my whole motor for a stupid cam gear :@

I shopped briefly for some A286 fasteners but all I could find was very expensive. I know of a project here we are using A286 fasteners for, but it is a high-end NASA application.

Well they also have 316SS. You need to find out what alloy they are using if you want to duplicate it since there are a lot of different stainless alloys out there. For example, if they are using A286, which is a corrosion resistant superalloy, that is a LOT different. It is a high strength steel, which depending on how it is heat treated can be up to 150+ ksi ultimate. 316ss is half that.

Air power systems use A286 studs and copper lock nuts in their turbo kits. You should contact them for metric sizes.

I have been trying to get a SM Turbo type of class going for a while now. The cars I build use A286 fasteners. I don't know of anyone else who can say they have raced- and won - endurance races in a Turbo Miata. 4 hours in 2008, 8 hours in 2009.
Seems everyone wants to build a better mousetrap. If you want a proven solution, you can get me at kverges "at" figdav.com. I have 2 built cars ready to race.
