is buyin the whole set a viable cost-effective mod, or should i just buy the crank pulley? also, how much should i expect to spend for the 2 belts needed?

 

Only the crank pulley is needed to get the performance gains. The others are just to have a balanced appearance. Not certain about the belt prices since my pulley hasn't arrived yet. A few posts have part numbers and/or belt lengths posted so you could easily call any parts shop with the information and they will give you a price.

 

Correct, the crank pulley does all the underdriving and a majority of the weight reduction, but the other two pulleys do help in a very small way with the weight reduction. As far as belts go, you can expect to pay about 10-20/belt that you need.

 

is unorthadox the only one out so far, and where can i get one?

 

I got mine from SummitRacing.com for $168.

 

yeah, i was tryin to order from them, via the internet, but i couldn't find it. i saw it in their catalog i got in the mail. well, they didn't specify 350z, but i saw the ad.

 

The Summit Part # for the chrome crank pulley is UNR-021011502.

 

awesome; thanks. b/o, but shippin 6/2.

 

how difficult is the crank pulley install? I've heard rumors of having to remove the radiator and use and impact wrench???? jeeze

 

It took me about 25 mins to install start to finish on a LIFT. You do not need to remove the radiator and you do not need an impact gun. Just read my review on it....
Oh, and the the 2 belts cost me a total of $26
