Unorthodox Racing Stock Sized pulleys are now available for the 2003+ Nissan 350Z and Infiniti G35. The main purpose of the stock sized pulley is to lose as much weight off the crank pulley, and turn that extra lost weight into HP Gains. These do not underdrive the accessories, and work great with superchargers or competition stereos. Includes Crank Pulley, Alternator Pulley, Water Pump Pulley and Bando drive belts are included.

The earlier VQ35DE engines had a second idler (fan pulley in the diagram below) on the alternator/power steering pump belt. But it wasn't really necessary, and Nissan deleted it from the later engines (starting in August of 2006). In doing so, the pulley assembly was replaced with a small spacer to take up the gap between the timing cover and alternator bracket. This kit gets you that spacer as well as a new OEM alternator belt, so you can perform a like-stock conversion using genuine OEM parts.
