Ok so I have an 06 350z rev up, and I just installed my unorthodox underdrive pulley. As I was installing them I noticed I had no idler pulley stock?! im the second owner of the car and the first owner was a cop and kept the car all stock and had everything done at Nissan so I don’t think he pulled it off and the belt that was on the car was still the original Nissan one...so im very confused. Does 06 not have that top idler pulley?? Or am I just missing one for some reason? And if I am missing it do I have to have it? My car is running perfect (knock on wood haha) so idk

 

What size is your OEM belt? It was probably just removed, no big deal, its better of gone.

Belt size 450 or 465 ?

 

Theres actually an idler pulley removal modification that removes the idler pulley that is not needed on the earlier 350Z's from what I understand the later model 350Z's had the pulley removed. The first pick is with the pulley on the second pic is with the pulley off...

yes! thank you! thats the exact one thats missing! as for my belt size i'll recheck because i pulled off the stock belt and the belt size that was recommended by unorthodox wouldnt fit (it was too long) so i had to guess and go down in size untill i found the right one. so its ok to be missing that one pulley?

 

no prob removing it, mine is gone and the 07 and newer cars that run the DE don't have them. I would search the thread about the pulley removal, someone posted the size you need.

 

Ok I am going to remove this pulley as I have on idea where it came from nor have i seen it on any z i have worked on before. Anyone with a stillen supercharger if you could chime in and maybe tell me if this is an additional pulley from stillen. but i did a crap *** drawing showing where this idle pulley is. I see it servers no purpose anyone able to chime in here and let me know if this comes with the stillen charger.
