How much would a shop charge you just to do this I'm curious?

prob 30 min of work at most

so it depends on shop rate really.

I stripped one on my S2k, I got a threaded insert coil kit and did the repair myself, it worked perfectly and torqued down fine. You just drill out the hole, then tap with the supplied tap tool, then put in the insert and you are done. It was very tight to get at, so I used a 90 degree drill and it worked fine.

Did you fixed the repair with the same size thread or did you went up a size a little due to the thread being damaged? How much was the coil kit you got for and where if you don't mind me asking?

why would you go up a size when you dont have to?

can get the whole kit at autozone for 20 bucks

,
with a new coil thread repair kit you can stick with the same oem size bolt and thread size. I bought my repair kit from a shop that sells tool and cutting supplies for machine shops in my local area, but you should be able to buy one from some of the auto parts stores in your area. The kit should come with the proper tap, new coil threads, and installation tool, then all you need is the proper size drill bit which will be listed on the kit. There are various length of threads, measure the threaded portion of the bolt and try to match up the thread length to the threaded size of the bolt, I can't remember the ones I used but they were something like 20mm or 30mm long or whatever the threaded portion of the bolt was. Just be careful when pushing the drill into the hole so you don't go through the block, when you are drilling out the old threads they will be very soft and you will push through them very easily when you get to the end of the old threads the drill will bottom out and you will feel it, stop drilling at that point and pull it out. Same thing with the tap when you get to the end of the hole it will bottom out and you will feel it hit and get harder to turn, that is where you stop. When you cut the new threads with the tap use some motor oil on it, then go slowly one turn at a time, remove it and clean it by dipping in a cup of motor oil then insert and turn again, remove clean and repeat every turn until you get to the end. Then run the tap through it a few times to clean up any residue. I find it easy to dip the tap into a cup of motor oil to clean off the residue. The tap will bring out residue on removal so it is a way of cleaning out the threads.

You can find thread repair kits on Amazon or through industrial suppliers like Grainger (local pick up may be available) or McMaster-Carr.

Make sure you get the proper size drill bit.

I haven't read the whole post, but I would drill and tap it one size larger and use a "threadsert". It looks like a setscrew with a bolt hole in it and will last much longer than the helicoil you pictured. It should have adhesive on the outer threads. Use red loctite if it doesn't. Make sure the threads you cut are clean and sharp. I would degrease them and let them dry well to ensure a good lock.
