hahaha, holy cow dude, like mrthins said, read the post again 
i have never really liked ebay parts and try to stay away from them because they seem to have fitment issues 90% of the time, but sense ebay seems to be the only place that has what i want i guess i'll have to try it again

WARNING: Light weight aluminum pulleys do not dampen belt slap. This will degrade the longevity of an engine, and as well can lower steering pump pressure from less rotation per engine revolution.

isnt it less rotation if its an under drive pully? mine is just a lightweight pully its the same size as stock and i had no loss of Alternator power or power steering power.

i don't know just how much truth there is to that but i like to play it safe and avoid crank pulleys that do not use a damper. some will say that the ka's are internally balanced and don't really need a "balancer". i put balancer in quotation marks because some question as to whether the crank pulley is really a harmonic balancer or a vibration damper.
i like to believe it's both and therefor was placed there by nissan engineers to deal with the torsional vibration and belt resonance (belt slap). both of which are not a problem at low rpms but can be at higher rpms. i haven't botherd looking too much into the matter so i could be wrong.
this is a conclusion i came to years ago and don't see a reason to change my opinion. so unless i can see proof i'll just stay away from these crank pulleys and recommend that others do so also

Yes, $150 plus shipping, plus core deposit, and I have one for you, I guarantee a minimum of 6 wheel HP for NA, and 12 wheel HP for forced induction, this is compared to the stock manifolds, that's also without any work done to the head.

My problem with aluminum pulleys is that there is no rubber damper to absorb the belt slap that will occur at slow and fast RPM speeds. The belts begin to slap (or vibrate as revolutions increase). This can wear down on the bottom end assembly, mostly crank bearings. In my case I rev the **** out of my engine, and to date I still haven't seen any dynos on the internet of a KA with under drive pulley that can beat my 162 whp, so do I personally think aluminum pulleys are bogus.... yea
If anything it's better to invest into an aluminum or lightened fly wheel than it is to invest into a aluminum crank pulley, if the objective is to drop over weight inertia.

but aftermarket pulleys are. so, anyone have crank pulley they have had on for awhile and not had a problem?
