V-specs can get great lifetime if taken care of. Mine is just now starting to show signs of wearing out, and it has 11+ gallons on it so that's reasonable. I would recommend a rod and bearing change. If it's still got good compression a rod and bearing change will extend the lifetime. You can check your crank pin with a good set of digital calipers.
As for the difference between the 2 rods(assuming that is what akiyama77 is talking about), the ninja/speed rod is much better. It is made better, and has an oiling hole in it to provide better lubrication. It is a great upgrade for the standard v-spec, and is only $5-10 more than the standard v-spec rod.
