Try going to your local hardware store and purchasing some "Easy outs" or some "Extractors"

OR IF YOU HAVE A WELDER..

Take an ordinary nut, one that's I.D. more-or-less matches the OD of the broken stud. Take your mig-welder, and set it to a high-voltage setting (I use 5). Hold the nut in your hand (don't worry, you can let go as soon as it's tacked... if you hold on too long, you'll melt your fuckin hand). Okay you've got it tacked. Now. Lay a brutal weld into it. Just fill the damn thing up with metal. Try to avoid any air-gaps... get it good and hot. The whole nut should be glowing.

Give it time to cool. Now simply un-thread the bolt you just made...Easy!

OR

step one:
you will be drilling the bolt out completely, along with the original threads. You need to determine what size the stud is, and drill it out one incriment higher than that.

so... go to the hardware store, and get some brass pipe. You want the kind with a tapered outside thread on both ends. Length doesn't really matter, get one that's a few inches long so you've got something to work with.

okay, so now you've got your brass pipe, and you've got your oversized drilled manifold stud-hole. Take a tapered-pipe-tap and tap the oversized hole the same size as the brass pipe you bought. Okay, now thread the brass pipe in NICE and hard. (the length will come into play here... you'll be turning it in with a pair of channel locks or vise-grips)

With the brass pipe threaded into the hole, take a hacksaw or a cutoff wheel and cut the pipe as close as you can to the head. Then take an abrasive-pad on your pneumatic die-grinder and grind the brass until it's ABSOLUTELY flush.

Sweet. now you've got a fresh hole with no threads. Tap the hole the correct size for your stock turbo stud, and thread it on in. BAM. done.

BTW, you are using brass rather than tapping into the aluminum because brass, like steel, has greater clamping force with smaller threads(larger number/per inch). Unlike aluminum which has greater clamping force with larger threads (smaller number/per inch)
