Definitive ka24de crank pulley question

[NashT]

Hey guys i recently picked up a full set of NST under drive pulleys for a steal.

Im only planning on running the crank and water pump not the alternator pulley.

Anyways ive been reading previous posts on here and on nicco, and am now skeptical about running the crank pulley.

Does anyone have any real experience with any negatives running an aluminum crank pulley?

I understand the ka's crank is only half ballanced, and the stock crank pulley has a dampner ring weight for vibrations, but im guessing its not actually a weight for the crank like on an old v8 with a harmonic ballancer.

Basically, if I run this NST crank will I run a risk of spinning a crank bearing?

And for the guys who would argue to only use the stock crank or ATI, what about when you change fly wheels to a light weight one, that in turn would change the ballance weight of the crank on the back side. (Just a comparison)

And no i dont care about the insignificant hp gain if any, i just couldnt pass up buying this NST set for 80 bucks.

So has anyone had any negative issues arise from running an aluminum crank pulley?

Thanks and sorry for the novel
