EPIC nuts/studs loosening thread (reposting stupid stuff without reading = warning)
#988
tighten them up, tack weld at the flange. relieves the stress from the studs. they stay tight after that. you can still remove the turbo later if needed by breaking the spot welds. you don't have to tack all the way around either. just the top and maybe 1 or 2 on the side (vertical) front facing side, so you can easily remove them if needed. spookyfish tacked the bolts to the flange, but i think if the bolt breaks it won't stop the problem, although i don't think he has had any problems.

This approach might provide enough thermal isolation to eliminate the need for megabuck inco hardware...
But this is all a guess, having never seen the manifold. Maybe something is making this approach unworkable?

I don't think extra meat in the manifold will matter like you think. I have my uuber hardware in the stream now, and I trust it more than I do the iron the manifold is made out of.
As for the standard stuff, it would just prolong the amount of time it takes for the studs to stretch, but it wouldn't prevent it, unless you aren't on the track long enough for it to happen. In which case it may work. But doing so would only be a guess.

and your right, it may only "prolong" the amount of time it takes for the stud or bolt to break, but there's no need to guess, it absolutely will prolong the time before it breaks. my other 3 bolts that are not exposed to exhaust gas have been on there since 2003, for over 60k turbocharged miles and over 30 trackdays. (some of them 2.9-3.5mi. tracks, lots of wot time) so while it's possible that they will break at some point, i haven't found that limit yet.
i can't tell you how happy i am that i didn't spend 4k for a new turbo setup, or even $125 for uber bolts. my buddy threw on a weld that took literally 20sec. and $0 dollars. and i can still remove the turbo easily when the time comes.

here's one i took back when i had it done. i can take a daytime pic if you want. (that's a shitty phone pic) but i think you get the idea. don't know what i'd do if say the lower right bolt was messed up or exposed to the exhaust gasses. i guess i could've had the mani. welded to the turbo off the car or something. but that would've been a bigger pita. like i said, i'm lucky it was just the one easiest to get to bolt that was breaking.
i actually just had the top left bolt hole tacked shut. no need to have a bolt there if it's welded.

Shameless plug. There's a tubular absurdflow manifold that'll directly replace the BEGI piece and has none of the flange holes into the "steam". Through bolts are possible too. Pic below of the first and only (hit refresh or F5 if no pic shows). It's NOT a log mani damnit.

you don't "think" , but i "know" from experience. and it's not "extra" meat that helps, it's "any" that makes a difference. i'm lucky in that my manifold casting only had 1 bolt exposed to the exhaust gasses inside. others have 2 or 3, and all of them stretch and break.

I see your welding trick is working for you, but you must admit it isn't the most practical solution for everyone. Wanting to switch turbo's, or come time for rebuild, it could be a bit of a nuisance. I myself don't take joy in grinding off welds, especially on a 1000 dollar piece.
But, Its tough to knock it too much if it works. However, I still prefer my solution. Lucky for you, I'm quite alone on that one.

You had the guy weld additional material over the bolt holes, is that what your saying? From the inside? That's what I was mentioning, and although its a fine Idea, I'm not putting my stock in it.

also, i understand what you are saying about removing the turbo, but for me, it's not a problem because i don't remove my turbo every other weekend or anything. as a matter of fact, i've never removed my turbo in the 3 years i've owned the car. if i remove it, it's because the turbo's dead anyway's, i'll install a new one, tack it, and not touch it again until it dies too. and it sure is nice not having to worry about it. realistically, i can probably remove that weld faster than i can remove the lower right side bolt! ironic huh.

Nice ^^^^^^ yeah, i bet those studs/bolts would never have a problem at the track. as long as they're decent quality (but not $125 bolts) they would probably last forever. is it that the cast mani. can't be made like that at the flange/throat area? how much would a manifold like that cost tim?
$600, tight radius weld elbows are $$$ unfortunately. But that mani with a 2560 and my 3" downpipe made 265rwhp @12psi on my '94 1.8.
I'm making one of these in a vband/ewg style in a couple weeks.

that's serious horsepower for that turbo/psi.
