Any boosted road course k20's?

Hey guys, was just wondering if anyone has had a boosted k20 or k24 survive multiple track days and track day abuse. I've had my N/A k20 in for about a year now and am looking to get more power than an an N/A setup can provide. I plan to use quality parts ( full-race kit with a gt3076r tuned by mikey at profunction) and run 8-12 lbs for next year and be between 320-350 whp.

My main questions are....

-Can a k20 turbo setup safely survive 20-30 minute sessions at full throttle in 80-100 degree heat?
-Is my factory lsd strong enough to survive this kind of abuse?
-Is downshifting constantly at high rpms risky with a turbo setup?
