The 2.5's have a longer stroke right? Having a longer stroke would increase the inertia and the distance the piston travels for every revolution of the crankshaft. This would cause more stress on the crank and wear on the rings at higher rpms, but wear issues aside, what else would limit the ability of the 2.5 to make usable power in the upper rpm range? A 2.5 spinning at 6 grand is going to be moving a bit more air than a 2.2 at the same speed, so I can't help but see it as a matter of flow. If the intake, head, exhaust, and cam profile on a 2.5 were modified/chosen to optimize flow in the upper rpms, and the rotating assembly balanced, wouldn't it be possible to build a good high rpm engine out of one? I'm not trying to start any arguements here, I'm just curious to see what everybody's reasoning is behind their opinions, and hopefully learn something in the process.
