so you cant thread a nut on? if you can put a nut on and tighten it up. then put another one on and tighten it up against the other, get 2 spanners, and make sure they are super tight against each other. then using the in side nut undo it, hopefully the stud will come out.

you might have to drill it out and rethread the hole worst case

I cant remember what size the thread on the stud is but this is what you need to do:- Go to the hardware shop and ask them for a "die". This is a tool that you will screw onto the stud and as you screw it on it will make a new thread. I would also suggest buying some tapping oil/grease to 1) make it easier to put a new thread on it and 2) if you get the greasy/thick tapping oil the metal shavings that will come off wont go everywhere they will just get collected in the grease. Because you have wrecked the thread on the stud, you would have to get the next size down thread die so it will actually make a new thread. If you know what i mean. Then buy two nuts to suit your new thread that you have made, lock them together, then turn till your stud comes out. Hope this helps cheers.

hey i know this doesn't help you right now (i'd just cut it down and use an easy out btw), but the longer studs don't matter, i also found that when you buy rb30 studs they often give you the toyota one which are longer but still fit, i used them on mine no worries!

yellow pages they call them self's thread doctors but i would have a crack grinding it flat so a spanner would fit on it

If the thread is still ok, put two nuts on it, then use the nut closest to the block to undo it. Otherwise, get yourself a set of....friggin.....snapped bolt removers....what the hell do you call them!? Gone totally blank.

Tack a Nut on the thread, use a Spanner to remove, quite an easy job mate.

See a plumber and borrow a stilson wrench, they are designed to keep inceasing jaw pressure as you try to undo the bolt. I have used them in similar situations many times over the years.

Heres a trick, Get some acetic acid/vinegar and soak a cotton wool ball with it and strap it/rubber band it to the place where the stud goes into the aluminium, keep it wet with vinegar for about 2 to 4 hours. Then use vise grips to unscrew it. The acetic acid/vinegar dissolves the aluminium oxide that holds the thread of the stud in the head. Best not to use a weld on the stud as you can often damage the thread in the aluminium head, you might need to helicoil it anyway if it removes some aluminium thread material at the time it comes out, edit: ie. Welding a nut means the stud is forced sometimes to tear the thread in the head when it does eventually turn without loosening some of the aluminium oxide first...
