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

1slow370 · 04-09-2010, 11:57 PM

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?

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!

Anyone have any Dyno runs of their own yet?

NST,

I sent you guys a PM last week, still haven't heard anything. Any chance you can get back to me?

I'm at over 1k miles with the NST pulleys and new belt, and I've not had any issues. I really love this mod. As for dynos... none. The gains are negligible, but the response feels great. I love shifting into 3rd and punching it... the engine winds up much easier and gets into fel... er passing territory easily

Thank you for the feedback. It is very much appreciated.

Thanks again

I finally ordered these, can't wait to put them on!

elmz · 05-14-2010, 01:54 PM

Has anyone placed an order with NST recently and have not heard back from them? I'm a little concerned, I haven't received any type of confirmation or shipping info and I have already paid for the product. It's been 4 days(paid and ordered on 05/10) and so far nothing. I'm not trying to rub their name in the mud here, but I think I have a valid concern.

I've sent them multiple emails from their site and this forum, also called and left a vm.

elmz,

As I stated on the phone today... unfortunately you did not include your first and last name, or your order number, with your PM. Unfortunately, I have not received your emails either.

As we spoke on the phone, we expect your package to ship within the next seven to ten days. You will receive an email with tracking information as soon as your package has shipped.

For anyone else who may be interested in this kit. We are sold out at the moment, but more kits are being anodized as I write this. We expect to have plenty of inventory and to start shipping packages in seven to ten days.
