A "typical" HPDE session for the car goes like this 
:
1. Ten minutes idling in the cold pits with the occasional rev.
2. Clutch stall when the grid worker waves the car out.
3. Startup and then a small burnout.
4. Brisk acceleration and then mild braking for one lap.
5. Brisker acceleration and mild braking for two laps.
6. Hard acceleration and mild braking for 1/2 lap.
7. Heavy understeer and front tire grinding for one corner with a snap spin on exit.
8. Mild acceleration and mild braking for one lap.
9. Brisk acceleration and mild braking for two laps.
10. Idle into the paddock and shut off.

The car I spoke of, had an oil cooler. That simple fact is, you can't race an engine and expect to last for 150K miles. Even with oil changes after each track event, oil coolers, proper maintainence, the engines will not last forever. In all honesty, running an OEM engine for 100 days on track, is pretty respectable in anyone's book. 
I would recommend using the best quality fluids and changing them before/after each track event, and being religious with track inspections, and general maintenence. All the key moving parts will wear out with time. Don't neglect things like upper and lower control arm bushings, front and rear hubs..etc..etc.
Have fun!

of course, none of those problem never existed in real life and I was dreaming all the time according to the owners.

Now that sounds better. 100 track events versus 100 track days. Of course all track event vary in terms of duration. I have had some one day events where I got more track miles than other 2 day events.
