Turbo exhaust studs

[nissanracer29]

Has anyone every had any problems with the exhaust studs on a t25/t28 or any other turbo? I have two broken studs on the back of my turbo and they are giving me a hard time. I have tried everything to remove them. I broke two drill bits and one easy out. Would it be ok to weld a new stud on there? Any and all advice would be greatly appreciated. Thanks :)

drill them out,

find out what size thread they are, go to an auto parts store, but new thread, and install them. worked perfectly fine for me when i was in that situation.

friends t28 is like that, there gonna drill the broken bolts out and put new thread in.

hope that helped.

good luck!

He said he broke two bits and an easy out already, so to me that means he HAS tried to drill it out, with no success...
Anyways bro, if there is any remaing stud on there, try to weld a nut on it and put a socket and breaker bar on there to back the stud out. That is pretty much gonna be your only option minus the easy-out. Spray a shit load of penetrating oil on it and let is soak for a good while first. Good luck, that shit sucks

If I can not get them out do yo guys think it would be ok to weld a new stud onto where the old stud still resides? I hate exhaust studs they always are a pain. Thanks for the replys keep them comming.

This happened to mine on my t25. Mine were rusted in and some broke. What I did was spray a shitload of PB blaster or whatever that spray is called...let it sit for awhile and spray some more.

What you can do is get vice grips, and tighten the SHIT out of them to the point where it starts smushing it to a square. Use another vice grip or somthing to tighten it. Then just start smacking it loose. Studs are a pain...

make sure after you get it out, to clean it probably run a tap through it.

just make sure when/if you do get them out invest in some stainless steel studs and nuts, they help alot if you ever need to unbolt them again, most likely you might have to its just good insurance

Take your time and drill it out. You will have to use a good carbide bit not those cheap one's. Also soak the bit and stud in oil as you drill, and at time dip the drill bit in water so it will cool off. (too much heat will cause the bit to seize and snap on you, so just take your time)

Start off with a smaller bit then go all the way through. Then work you way up wit a bigger bit until the hole is big enough for you to re-tap it to the correct stud size. Then re-tap the tread and put a new stud in. Go with ARP studs since they are stronger. (Earl's has the ARP studs)
I've done this a couple of times already, and this might sound weird but the quickest way of drilling out the stud was that I used a hammer drill with a concrete drill bit. I also kept it soaked it oil and it sure does cut down the stud much quicker than any other drill bits that I used. It will take you about 1hr to get out one stud so don't expect this to be a easy task.

GL and hope this helps...

this has happened to a colleague of mine not too long ago... like jbma said, make sure you don't go with those cheap bits... my friend went through like 8 or 9 before he finally threw down on the carbide bit. This bit should pretty much make it butter. Also, what he said to me is that a good preventative measure, if you haven't already done so, is to get a down pipe with a flex piece in it. He said this REALLY helps out alot, especially since you now know how much of a pita it is to replace studs.
