NEW!! Info About NST pulleys
I did and i will again choose Non Stop Tuning!
heres why:



The NST Scion tC pulley kit increases horsepower via great weight reduction and the underdriving of accessories. Superior to other available kits, NST kits also offer an Overdrive Alternator Pulley to optimize output for stereo system lovers!
Each kit is carefully crafted from 6061-T6 aircraft aluminum, tested and balanced to high tolerances. Every NST pulley is hard anodized for exceptional durability and is available in a choice of colors: Blue or Graphite Gray.
BENEFITS
Great weight reduction
- Average of 65% - 70% over OEM
Increased horsepower
- Average of 7 - 10 horsepower
Lower ET's & higher trap speeds
- Average of .20s & average of 2MPH
WEIGHT COMPARISONS-_________OEM-___________-NST-
Crank Pulley_____________________59oz___________14oz
Alternator Pulley _________________10oz___________03oz
Water Pump Pulley________________14oz___________06oz
Also some notes that NST would like to point out:
1. Our underdrive specs and stats have not changed.... our underdrive pulleys NST02020 are still the same size
2. the only difference is the pulleys now have holes drilled in them for a more cosmetic look
3. this results in a little more weight reduction
also on another note:
Prices may be going up soon because the price of aluminum has steadily increased over the past couple years. So anyone interested may want to take advantage of the $99 price tag (20% Underdrive Crank) while they can.
Also a note from me
im going to make a note that i am not an employee of NST and that this is just a customers review
i hope that this was helpful and if anyone has any specific questions feel free to send NST a message on AIM: NSTonAIM :D

i dont exactly know the effects of it on a turbo car, but if the underdriven scares you they have a stock sized pulley that is just lightweight!!!
i also dont know when the price will go up. but dont expect it to go up a lot. you should be good. how long do you think it will take to save up? you should be good

Your A/C will run a little bit slower than normal, but not so slow that it will blow hot air (anyone who tells you that your A/C will become a heater is full of it!)
You will gain more power at the wheels and your A/C will last longer because it is not working as hard.
The same as above goes for your water pump, alt, etc.
Another benefit of running the accessories a little slower is increased fuel economy. You will see better MPG if you install an underdrive crank pulley.
All NST pulleys are also lighter than the stock pulleys. Weight reduction leads to better throttle response and quicker lap times

Look for the screen name NSTonAIM if you use AIM and ask them to go into it further if you want.
you can search around for that, some say its a myth some say its true. i dont know exactly, but i believe i read somewhere that most cars wont even see any damage from it in its lifespan.
someone correct me if im wrong
