I am hopefully ordering the NST underdrive pulley tomorrow and just wanted to make sure of some things...
Are there any other parts im going to have to buy such as a new belt for the pulley? and just to make sure, everything will still work in my car such as my a/c and stuff. ive read about pulleys on other cars and they made things like that stop working. thanks.

 

When changing pulley sizes you have to buy new belts. It's not a big deal though, that information is usually included with the pulley, and you can just run down to Autozone or whatever and get the right belts.

 

I dont know about not working but make sure there is enough tension on the belts and to torque things down to spec.

 

if your getting the NST underdrive crank pulley, yes you will need a new belt. you can find all the information on on there website at www.nonstoptuning.com or if you have any other questions, u can always IM the NST rep on AIM. there SN is NSTonAIM. hope that helps you sir.

 

NST pulleys kick @$$ They list the proper belt numbers on their website and you can always find them on AIM if you have questions. You can buy these belts at your local parts stores and they are pretty cheap.

As far as your accessories go, I have been using NST pulleys for years and years on several different cars and I haven't had any problems.

There's a thread here that shows you what other pulley customers have to say:

NST FTW!

 

so their hasnt been any problems with the NST pulley concering power for your a/c and stuff? Props to NST then. thanks alot

 

Do youa ll have the underdriver pulley? or the other pulleys?

 

You won't have any problems either way. If you are on a budget and want to spend about a $100 then just pick up the underdrive crank pulley. If you have more money to play with and want a little more power and response, pick up the accessory pulleys also. You won't have any problems either way.

 

btw, has anyone measured the amperage output of the alternator? would be great if there was a comparison between:
stock vs
underdrive vs
underdrive w/ accessory pulley vs
stock diameter crank w/ accessory pulley.
