Pulleys 101...

MeetJoeAsian

I really have no intention of modding my car to gain anymore power and such...I did however kinda been thinking about getting another 350Z, pay cash for it, and just make it a project car....which KINDA led me to wanting to maybe do something here and there with my 370Z...

One of my coworkers have been nagging on me to get some NST pulleys for my car, and he said that all I would do is change out the OEM pulleys for lighter pulleys...I haven't been in the loop for over 12 years, and the last few cars I had, I never really cared to mess with, even when I had my 350Z...my whole intention of buying a powerful car is just so it is what it is...I don't plan on racing or showing it...but SOMEHOW, I've just been getting a little ITCH (you can say) to do a little here and there...

My buddy said the pulleys won't affect the car (as in messing up the engine)...now, I've read something about underdrive pulleys...what's the difference? And also, can someone give me a rundown of advantage of lighter pulleys or how it affects negatively or positively in the engine...from what I understand, when you change the pulleys, you're only changing the weight of the pulleys, and thus giving you better power? or something like that?
