Re: Suggestions for a fuckup?
drilling it would be a bitch for a few reasons, its wierdly shaped and made of hard *** steel... can you fit a piece of metal in two opposing "holes" and then use a longer bar to turn the tap out? or weld something to the tap... that could be tricky.. but probably not bad if you have a mig...

They make tap extractors that is an assebly of little bars that fit in between the flutes of the tap so you can turn it out, but they never worked for me
It is hardened steel so you will not be able to drill it, but I have had some luck shattering them out.
Usually I just try to shatter it and drive it through, then run another tap through to clean it up. If there are no threads left I go a size bigger or use Heli-coils

Try a tap extractor, or needle nose pliers, like stenseltizm suggested. Your tap was most likely mad out of High Speed Steel. Drilling that will not exactly be easy, even with a carbide drill.
My machine tools book mentions using an acid, to east away at the material being tapped, around the teeth of the tap. This will "loosen" the tap allowing it to be freed. Never tried or seen it though.

Just had to deal with the same thing in a my wastgate flange. I tried all that was mentioned above except the acid, none worked. Ended up using a punch and a 2# hammer. Then drilled it out and just used a bolt and nut, but a heli coil would work also.
