I didn't read all - but I had a similar fate so I thought I'd post up quick

cliff notes:

20G STi w/ 50-60k miles -

I had lots of blow by (a quart every 1-2 sessions)
Definitely detonated - it blew a hole through the piston (stock)

The octane of oil is like 2 - lots of blowby at high RPM/boost - ouch?

I had so much blowby the hoses all blew off/things caught fire etc

(don't mount your a/o separator anywhere near a turbo !)
