All i have to say is Easy! went well the belt used in a previous post worked great the belt said to be used was way to small. performance increase is good! its very smooth off the line (5 speed). here is the belt number from advance auto parts Dayco Poly Cog 5060755.

just installed mine recently too. I love how the car drives more smoothly. I have 5spd also.

But somehow it started making some squeal noises when the car is cold. I'm gonna re-tighten the pulley bolt and see if that fixes...

Sounds like the belt you are using is too big.

Actually mine did that as well a few weeks after install. Yet mine isnt underdrive. Whenever its cold it'll make this weird sound until I drive for a few minutes. I feel like it wasnt coming from the pulley side though.

I looked on the NST website and I'm confused as to which pulley to get. It shows a few different ones.

Were you able to fix that problem?

I'm using the exact same belt as you're using.. The sound it makes is like a bird chirping noise. And it does go away after car being warm

The squeeking noise might be caused by the belt not being on the grooves closest to the motor. Thats what happened to mine and it got progressively worse until I figured it out. Stopped the noise.

I searched a lot of threads to find the correct belt for the NST UD pulley. Some say that a 74.7" belt is perfect, some 75" and others say 75.5". I went with a 75" belt but haven't installed it yet. To those running the 75.5" belt, do you think you could have fit a 1/2" shorter belt? TIA.

i had the squeaking the dealer said was cuz belt was 1/4" to big but then sound stopped b4 replaced so forgot to change

Finally installed my NST UD crank pulley. Pretty easy install except for the awkward location of the belt tensioner. Gates K060750 belt was a perfect fit.
