Do a compression test and hope for the best. I've known people who have unfortunately completely blown out pistons/cylinders like this.
If the cylinder/piston is toast then my recommendation would be to just buy a "new" long block. Maybe use this as an opportunity to go F22 block and re-use your current cylinder head assuming it's ok.
Your other option in the event of cylinder wall damage would be to bore out the FRM sleeves and use Mahle pistons, which isn't a bad idea but I think the F22 long block would make more sense both financially, reliability, and for power. Sorry this happened man, any idea why the plugs were so loose?

And I would need to see if my Supercharger could become compatible..
But I appreciate the advice! Hopefully it doesn't come to that.
And honestly, I don't know.. we installed the new plugs when we were doing my supercharger but my friend is the one who put them in (and he's more savvy than I am so I can't imagine he just thought they were tight enough..). Unless he meant to torque them and forgot? I don't wanna go around pointing fingers though. Do you think them being loose was a good indication of why this happened?
That would be my best guess as to what happened. I can't think of anything else that would cause this, I personally have never heard of spark plugs just backing out over time, especially the interval that you described.

I noticed that your are running BKR8EIX plugs. One step cooler than recommended NGK BKR7EIX. Has pre-ignition or knocking been an issue with this engine?
Thanks!
Thanks!

^You can find a lot of threads over the last few years where people answer pretty much in the same fashion. The problem isn't the plugs you were using, but how they were installed I think.

The electrode length of those plugs are pretty much identical to the oem plat plugs, I've been running them for years. Given that the entire center electrode has been blown away I'd still suspect detonation, if it was just the ground electrode I'd blame the gapping technique and improper installation, but you had some other stuff going on there.

So I read a bit more about detention from that link above. When I installed the supercharger, I throw on the fuel pressure regulator it came with and the piggy back ECU from comptech. The kit was used so it's very possible the FPR wasn't adjusted for what I needed so running lean is definitely not out of the question. I should pick up an AFR gauge before anything.

FWIW... upon further research (Google a few times more 
)... the -11S suffix "11" means pre-gapped to 1.1mm (0.044 inch). "S" = special gasket.

I'm in the same boat as him as this happened to me last week. Except only my ground electrode broke in cylinder 2. My coil pack was covered in oil for me I think and all the other coil packs were dry and normal. P1399 code for me only.
Run a compression test, on the engine?

Here is a direct quote from the S2000 service manual:
"Do not adjust the gap of platinum tip plugs; replace the spark plug if the gap is out of specification"
Also, there is a warning image on the NGK spark plug box that shows a tool adjusting the gap - specifically prying up on the ground electrode, with a big red X on it.

Would it be to late to try to retrieve any pieces left with a telescoping magnet like this? https://www.amazon.ca/Master-Magneti...scoping+magnet
