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

birdmanx1 · 08-06-2011, 06:37 AM

Christian, I've had mine done for $150. There were absolutely no issues with the install.

CFZ · 08-09-2011, 12:34 PM

So with this pulley kit the water pump would slow down correct? is there any heating issue with these pumps. i dont know if its covered but Im not willing to read 30 pages to figure it out.

Thanks!

No the coolant pump and oil pump are controlled by the timing chain, which is separate from the belt/crank pulley.

The pulley belt runs the alternator, A/C, and power steering.

For those with this mod, any increase in engine noise over time? I'm talking those who have had them for atleast 6 months.

Kind of odd that we can get picture updates in the other thread, but can't get a response on here or from PMs...

NST Still waiting on that belt, or at least a good word on when they'll be in stock/shipping...

For those of you with these installed already, did you use the Gates K070786 Belt that comes from NST, or did you use the OEM one already on the car, and if you didn't use either of those, and got your own, What belt did you get and from Where??

I hope you eventually get the belt. I used the belt provided by NST for my pulleys. You can use the OEM belt but it won't fit the same as the NST belt. It was covered way early in this thread and that's why NST started providing the kit with the belt.

Here is what the package looked like for me, it came with M&M

Yeah, mine did too lol It was cool even though I don't eat them. I was notified on my invoice that they were out of stock, and would be back in stock by end of July. Well it's almost mid august now and still no word from them on if they're in stock (Even though the website said they were when I ordered, and still does say in stock) And I'm trying to be patient with them, but I really don't like having the parts sitting here wanting to install them, with no belt. And I'm almost about to just go to autozone and get one, but I want to make sure I get the right one since obviously the OEM one they'll have listed isn't right...

This is the only concern I have. Any experiences?

wstar · 08-25-2011, 06:53 AM

I never noticed an increase in engine noise from switching the pulleys on my car, and mine have been on a really long time. There might be some (it would make sense, since the stock crank pulley has an NVH ring), but IMHO it's pretty inconsequential given how noisy a modded car is anyways. If you have aftermarket intake/exhaust work, that's going to drown out any change from the pulley.

XwChriswX · 09-02-2011, 04:37 PM

NST Please check your PM's, thanks.

quicksilver08 · 08-11-2011, 08:28 PM

I ordered my pulley's friday and got them wednesday. I didn't order the belt though. Gonna go pick it up from o'reilly's tomorrow. And the m&m's were freaking sweet. Thanks!

Yeah, the pulleys arrived super fast.

Which belt are you getting, there's an O'reilly's up the street I can go to..

birdmanx1 · 08-11-2011, 08:31 PM

I hear you Chris, I would call just call Mike @ NST rather than PMing. The belt with the part number you listed above can be acquired from Autozone as well

wstar · 08-12-2011, 08:40 AM

Use the Gates belt, whichever model number (length) NST recommends for your setup. Gates is good quality stuff, and they're generally available from local auto places, although sometimes they have to order them from a local dist center (a few hours, or a day at most).

red6spd · 08-12-2011, 10:00 AM

Ok so instead of searching all 29 pages and 400+ post has anyone had any negative issues with these kits? I'm interested but my local performance shop who is very very experienced with cars in general but mostly the VQ series and they have warned me not to install a pulley kit on my Z.
