If the nuts are good enough a get a wrench to grab the hard part is over. The trick is to use an oxy-acetylene torch, small carburizing (low oxygen) flame and you want to quickly get the nut cherry red without getting the stud to match. The nut will then come off. The challenge will be to do this without setting the rust bust crap on fire.

I am trying to replace the turbo on my Syncro TriStar. It it held on to the manifold with three 13mm nuts, these nuts go on to studs which go into the manifold. I really don't want to break the studs. I can put enough pressure on the socket where I know if I go much further the stud will break. Three days of penetrating oil "3-IN-ONE 'High Performance Penetrant'" and no with luck other than my garage stinks. I've tried the tighten a bit and then loosen which seems to work with allen bolts and light tapping with the impact gun... they're still in place. What should I do next?
