Cup engines are rebuilt frequently because they are sprint motors, built to live at 8400+RPM and have much tighter tolerances, thus the parts "time out" and/or stretch (rods), and need refreshing to prevent a catastrophic failure from fatigue. I am no expert, but this is what I've been told about Cup engines from 3 separate builders.

This engine is different. It is pretty much still a street 3.6 motor, but bored out to 3.8, with some "special sauce" Porsche Motorsport parts added that kick it up a bit (997 Cup heads, for example).

I don't count hours, but its had about 13,000 miles added to it since the motor replacement in 2013. Maybe 1200-1500 of those are track miles, the rest are highway cruising, canyon runs, commuter miles, etc., where its just as happy. It is also fully smog compliant with stock intake, O2s, catalytic converter/headers, etc. I used to live in CA and it passed smog there about a year ago.

Hope this information helps...it really is a very cool, very unique GT3.
