Does anyone know who makes the Nissan SC that is on the Xterra? Is it Nissan? And if not Nissan than why don’t they make one for the Z as an aftermarket product?

 

I believe it is an Eaton M62 Roots-type supercharger. The Xterra only makes like 210 HP with the SC from an engine that is only slightly smaller then the VQ35 so, using this supercharger probably would do more harm than good.
