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?

Re: Any boosted road coarse k20's?

I highly suggest NOT trying this on stock internals. You will need a full size thick radiator (i suggest Koyo or a high quality custom piece). What core does Full Race use for there intercooler? I would suggest either a Garrett core or Bell Intercooler Core - as they are much more efficient than most others out there. You'll need an external oil cooler as well. The problem can be getting air to the radiator with the intercooler blocking the majority of the air flow

I think you'll want a clutch type diff - I don't think the oem can take the repeated abuse of coming down hard off the curbing. You may have issues with longevity of the transmission (for us it was 4th gear) as well.

For a road coarse car - I highly suggest fine tuning your suspension & tire set up. what is your current suspension & tire setup, and one what chassis? lastly, is your car already caged?
