I Need a Big Stud
Ok, since I'll be swapping studs #4 and 5 of this year (meaning I average one a month) on this ******* FM set up... I wanted to see who swaps studs, and what they do.
My issue is the studs I put in back out if I don't tighten the hell out of them.
If I do tighten the hell out of them, they break off.
I'm going to try wiring the next set in, wire the nut and the stud.
But I've heard of people putting in larger, American sized studs. What size? How do you do it? Any other advice? Is wiring a bad/good idea?
Plus, I have a friend who's a blacksmith, and he's going to forge me a custom wrench - how cool is that?

you dont need to pre-tighten studs. that's not how they work. hand tight, bottomed out is plenty.
i wish I could give away my secret as to why mine have never ever ever never come loose, but I can't. hand tight with audi-style turbo locknuts (deformed, copper color) and that's it.
do you run gaskets or something?
I even put anti-seize on mine. how's that for your luck.

Take your turbine housing off, and take it to a local machine shop to be re-drilled/tapped for M10... or send it to Corky. I had mad loosening issues with the studs on my DP. I tried Nordlocks and they've worked fine for about 6 months. If they back out again, I'll just tighen'em up... but I'll never have another turbo that doesn't use M10 on both flanges.

Yeah - I guess that M10 is the way to go. Too bad, I'll have to wait on the custom wrench then.
Things are SO tight in there, do you mill out any more access to the nuts?
Also, my studs don't really bottom. I've retapped so many times.....

that'll work, it's what Brad ultimately ended up doing.

Can you use bolts? My studs were backing out all the time, I put nordlocks and they still came loose. I put in bolts with the nordlocks and no problems. They are actually pretty hard to get loose.
I still don't know why I went with studs to begin with? They were annoying to screw in and have to put the nut on top. The bolts just fit in, spin and hold.

My original thought was to slit the sides of the turbo, to allow bolts to come in. I still sort of like the idea, but I imagine it will do bad things to the structural integretiy of the turbo.
Speaking of risking integrity.... Can I mill out any of the turbo to make it easier to get a wrench on it? What size nuts do you use when you go to M10 studs? I keep thinking removing 5 cubic mm of material would give me 30 degrees more swing with my wrench.
Anyone have any pics of this conversion? I'd love to see how things look.
Also, why can't you do it yourself? Drilling and tapping is not that big a deal, and there are already guide holes there! Maybe this time I won't tap all the way through...

Where's a good spot to get studs from, McMaster? Any size suggestions?
I still like the idea of opening up around the nuts a bit to make installation easier.... Has anyone done this?

If it's the one I think, my friend is going to make me a wrench just for it. :-) I keep that stud pretty short, too. Anyway, I ordered me a bunch of studs, a variety of nuts, some NordLock washers, jesus, I spent way too much on it, but I'll be glad to have it done. I would have bought a tap but a friend claims to have one up to the task.
