RB Motor - Underdrive pulleys?

[MELLO*SOS]

Where can I buy a set of underdrive pulleys for my RB motor?

Specifically, my crank pulley had a little chunk broke off and I'd rather replace it with a CNC'd underdrive pulley than a heavy stocker if possible. I've searched around but all I can seem to find are adjustable cam pulleys for the RB. :( On another note if you're sitting on a stock RB pulley PM me for a possible sale!

Thank you for your help!

I'am in the same boat. My crank pulley is destroyed.what i did discovery was that on http://www.driftfactory.com/inst.php
site was that they used an rb25 crank pulley on thier rb26 click on the link so this leads me to believe that we rb25 owners can use an rb26 crank pulley http://www.atiperformanceproducts.com/products/dampers/charts/damnissan.htm
Even though its costly it seems like a quality product. but i wonder if it will line up with all the ps pump and everyhting. Anyways hopefully there is sopmeone out there that has a solution or knows more about this. my crank pulley is jacked.

From what I've read it seems that the RB motors need the harmonic balancer to absorb vibrations, otherwise the oil pump is destroyed. The ATI pulley looks like the way to go..

For future reference...
