UR has a stock diameter pulley (Ultra Sc as opposed to Ultra S) for the VQ35 on their website, but I haven't found it being sold anywhere else. I would prefer this over an underdrive pulley so that I don't have to change the belts also, so has anyone bought this, or have any info on it, or is it just some generic pulley that they are advertising?
Here's the link:
