i was going around it to clean it up and get it ready to paint and found a broken bolt in one of the intake inlets so i started to try and get it out first by cutting a slot in it as it was still sticking above the hole but that didnt work so i filed the rest of the bolt flush with the hole all is good at this point then i start drilling the bolt still doing good i was about a 1/8in into the bolt then a budy showed up a was going help me out hahaha well what he helped me do is he put a torx bit into a screwdriver handle i did not have my easyouts on hand and he thought hey this the same so he tapped it into the nice little hole that i had drilled into the bolt then broke the tip off and now i cant drill it out any more
any ideas would be great or am i screwed

The torx bit is not hardened so it is not surprising that it broke.

I was in the same boat accept it was an broken easy out. the only thing i did was burn up about seven different drill bits, used super small ones to drill around it and create slack so i could peel it out with a triangular chisel/knife type thing(any thing would work here)
I finally drilled it out and helicoiled it.(it was an exhaust stud)
This is a similar strategy to what I did on an intake bolt. I drilled a small hole next to the broken easy out and made a tiny hook to yank out the broken piece.
Krazinite, be very very careful. If you can't get a welder to extract it (which is probably the cleanest method and you may not need to helicoil/retap), be super patient with it. Plan on taking a long time. If you rush it, it can get real ugly real fast. Don't drill deeper than you have to. There are usually enough good threads below the broken bolt to give you something to screw into with a longer bolt when you are done.

Take a small chisle and grind it so it's very narrow.
Use a simple butane torch to put some heat around the broken bolt. Hit it with penetrating oil, let it soak in for a while. Heat it again, more oil....
Then use the chisle and small hammer & try to get a bite on what's left of the bolt and unscrew it.
You might even let the pentrating oil work overnight...
Buddies always have the "best ideas"...don't they
