I will now join the ranks of idiots who do not safety wire

I was thinking about the whole problem of studs backing out etc and wondering how manufacturers deal with it without vbands. I wonder if manufacturers (like garret) are able to manufacture both studs/fasteners and the housing (turbine housing or manifold) with much higher quality thanks to high-quantity-cost-efficiencies.
Reworded, I wonder if OEM (or near OEM) manufacturers are able to cheaply produce parts with very very high tolerances for cheap since they produce ten billion of em.

The people with these fastener problem are apparently putting hardware through stress that manufactures chose to ignore for obvious reasons.
I hope that with the correct oil pressure, safety-wire, and a safe tune I'll be able to track this car for a long time.

No OEM is designing for the abuse that is being spoken about here. We are even talking about a higher specific output than most supercars, and a duty cycle on all critical parts higher than most design targets.

The track I ran on Saturday has a 3x apex where I have an 11-second period of sustained 1.25-1.4g loading. lol

Which jig did you get? I'm thinking of doing the same thing since I have the turbo off anyway to replace the head. You can do it without the jig on a drill press but I'm thinking the jig will speed things up.

You know that wont work for nuts but it will be great for the bolts.
Was looking at this for the nuts MOTORCYCLE TOOL SAFETY WIRE TWIST LOCK Nut Drill Jig:eBay Motors (item 370143850607 end time Nov-08-09 11:12:26 PST)

That is Safety Wire Fail. If you're gonna safety wire, do it right:
Safety wire - Wikipedia, the free encyclopedia
Also, I think the .032 SS safety wire would be fine for your application. The inconnel stuff is probably overkill (unless you split the cost with a couple people).
Chris
EDIT: Also, when drilling holes in the bolts, drill atleast two so that it is easier to pick a hole without having to over/under torque for proper alignment.

I remember the bolts for Tial's housing being much smaller than cast housing bolts, what's the reasoning behind that? I'm no engineer, but to me they look too small.
Trey, are you buying bolts with bigger heads? The tial supplied bolts won't be fun to drill. Also, you're going to run into a problem with the oil return flange, it was hard enough fitting the tial bolt in there. Get one of these, the begi one is too bulky.

I'm stuck with the tiny bolts, but I bought a jig to drill them for .022 inconel...any reason you can see why this will fail. I have enough clearance to get the wire through and who knows what thread begi used on these fittings.

I don't know enough about safety wire to comment on the size, but I'd trust Rennkafer/Miatamaniac92's advice and go .032". They seem to know what they're talking about.
I just figured a smaller head would be tricky to drill, especially, two holes, but if it can be done, I don't see any problems.
