NST (NonStopTuning) 370Z VQ37HR Pulley Kit Review w/ Dyno Charts

1slow370

so nst what is your opinion on needing the center hole sanded out for instal should it be a hard press, slight press, slip fit? just wondering i have the FSM so i can see what it should be like for the stock one but i'm wondering if the install for these is different. and since his tech sanded the anodizing out of the bore could there be any complications from that?

NonStopTuning

NST pulleys are built on the "tighter" side. We believe this is better than a loose fitting pulley and will hold up better in long term use.

Sometimes, because of the difference in the OEM factory tolerance levels, our pulleys will fit tighter on some crank snouts when compared to others of the same make and model. This does not happen often, but when it does, some light sanding is required to remove a bit of anodizing to open the bore up just slightly. This will NOT lead to any abnormal wear and tear and will NOT lead to any issues. Just use your good judgment when sanding and try to remove the anodizing evenly.

Thanks again everyone, good luck and have fun with all your projects!
