With a built bottom end (sleeves, crank, etc), the same old nissan lump has hit 500hp/liter.
needing sleeves to make 1000whp is lame!
On a serious note though.. there's a lot more factors here than just a peak hp number. Making the power at a high RPM is easier on a motor. Low end torque is hell on a motor, just as much if not more so than revving to the moon. The harmonics change throughout the RPM range and different parts take different beatings at different RPMs.. where the power is made affects what parts of the motor take the beating. When you have a high hp 2 liter you're making your power by revving the piss out of it which keeps the beating pretty much localized to the bearings more than anything else. A motor that makes massive low end and midrange power like David's Firebird will take much more of a beating on the rods, pistons, etc, due the power it's making at slower piston speeds.
