Red face 12mm studs: how bad of an idea is this?

Ok so goggle search turned up jack squat.
MT search turned up only the 1 "stretched studs" thread in which I don't want to post since people will go ape-**** for not reading the whole thread and possibly asking a question that's been answered in one of the eleventy billion pages of that thread.

Anyways, my question is super simple:
would running 12mm mani-to-turbo studs/nuts run into any physical limitations? any other issues?

mani in question is a begi log.
hotside in question is a garrett t2 .64ar

TIA

Someone's done this and taken pictures, I think in the stretched stud thread. Worth a search? They looked ridiculously huge (that's what she said), but if they work, they work.

meaing the t2 flange is too small altogether on both the mani and hotside?

I'll keep digging of course.
The 10mm holes already in the mani look like they've plenty of room for enlargement without intruding onto the port, what I'm worried more about is the hotside.

The last time I lost a stud, it shot out under pressure and pinged the side of my fender, I thought something badwrong happened. :-)


Anyway, after putting these badboys on:


I stopped having problems. Not a single problem. Not loosening, not turning, not backing out, not just being gone one day. They've been f'ing perfect.

Basically, it was just this:


Big studs. And decent lock nuts. I don't even think all the threads are engaged. But I've had so many sets of threads, etc, nothing ever worked. You had two choices, break the studs/housing/nuts/etc or have them back out. Even if you tightened them weekly, you'd lose one once in a while.

I'd done Nord-Locks, I liked them, but they didn't actually work. :-)

Plus, how often do you get to bust out your mexican potato sack shirt?

M12 nuts on a T25 housing would likely be impossible to tighten.

Hold a 17mm box wrench next to your turbine housing and decide for yourself... Not a chance.

Eh, it was worth a shot lol.
I figured it'd be unlikely but better to ask then to keep wondering.
Thanks for the responses
