Which is better? The manufacturers should post the weights of each. I think the NST looks better, not that looks matter.

Prices are: ZPI $105, NST $110, both include shipping.

Which will you choose and why?

NST for various reasons. Their products are proven reliable. We use them on our shop cars and they use them on their cars. Furthermore, they are going to be used on a professional road race Scion tC that both us and them are involved in. Need I say more?

From a certain perspective, "because we're in bed with them" isn't actually a convincing argument... I'm not saying that their's may not be the superior product, only that yes, you may need to say more.

I was wondering when this question would pop up.

ZPI, NST, Unorthodox... all three companies make pulley kits. I'm not necessarily saying Unorthadox makes a Yaris pulley yet, but in general when pulleys are discussed these are the three companies that come up.

The difference is that NST's focus is on pulleys. They don't dabble in much else because they don't feel they have to. It goes along with the old saying, "stick to what you know." NST knows pulleys. This is why when Toyota was ready to donate a race car, they signed NST on to make the pulleys for their Scion. TOYOTA did.

One of the coolest things about NST is the company's connection with their consumers. If you have AIM, you can add NST to your list (NSTonAIM) and ask the president of the company anything about their products or cars in general. Trust me... I've spent countless hours over the past month or two talking to Mike about his products, his company, and the tuner scene in general, and I've learned a ton. He has a lot of great stories, pictures, links, and other things to share with anyone interested in NST products.

I am not going to say anything negative about any vendor on this site. All I will say is I encourage anyone to go to scionlife's forums and search for ZPI and NST and read what others have said about each. I did.

Also, when NST comes on to support any community, they grow along with it. The Scion tC community was a good supporter of NST, and when TRD decided to release a supercharger kit for the tC guess who eagerly started making kits to raise PSI numbers on their TRD s/c kits? I don't zealously support any vendor that comes on this site unless there is some kind of reciprocal advantage in doing so, and I'm telling you flat out... I want NST around down the road as a supporter of this community in case their services can benefit us again.

Our support of their CR-Lite pulleys has already paid off... if you go to the link below, you'll see that they're already planning to make two more lightened pulleys for the Yaris. The date is TBA, but from what I hear you can expect them sometime in the summer. :thumbsup:

A pulley is pretty simple. You will not see a difference in performance in either piece. A $5 dollar increase is fine for NST piece considering it is anodized. If you dont care about color, Get the cheaper one and save $5 dollars.

If I didnt already have the money down for the NST I would buy the ZPI. Plus it is available today.

I have spent a lot of time talking to the guys over at ZPI in the past few weeks… And I like what they have to say, and I like how straight forward they are… In short… I trust them… I don’t know much about NST, but it’s only a $5 difference… Maybe if NST and ZPI can post the weight of there Pulleys that might help the decision making process!

If I remember correctly, the ZPI actually mentions their weight (1lb I think), but I might have misread...
In any case, I'm not in the market for pulleys... yet :P

I can always visit the guys down at Unorthodox Racing if you want (have couple friends that work there). As long as there's enough market for it, they'll make it. They're only 20 minutes from me.

Get a list going and I can see whats good.

We measured it on our shipping scale.. it tips in at 0.9 lbs.

I think this weekend I will take it to the grocery store and ask the butcher to weigh it on his "legal for trade' scale for a accurate measurement. I'll make sure he wears his gloves. :D

Oh yes the inevitable this vs that thread. I don't plan on doing any mud slinging or fanning, but much like chino I did some searching of my own. I started by asking Mike from NST (NSTonAIM)some questions. He answered all of my questions and invited me to search about NST on the internet to see what others say about him.

Both NST and ZPI have a large presence over on www.ScionLife.com. I did lots of searches and read through a lot of different threads. Everything is there, people talking about customer service, quality, price, everything. I could not find anything negative about NST. All those threads and not one bad thing said about the company, the product, or the people! I never thought I would find a company in this industry with 100% positivie feedback, but NST has such a reputation!

I also noticed that NST has more to offer the Scion community than all of their competition combined! Mike says they will have a lot of cool stuff in the works and will be happy to support the Yaris crowd in much the same way that he does the Scion crowd.

My vote goes to NST. I have seen nothing to sway me toward the competition :headbang:

In my opinion, a Pulley is no Rocket Science (correct me if I'm wrong)... so at the end everything comes down to the service an support that the vendor offers and I think NST is LITTLE bit ahead on that department. I'm on the NST GB and they have promptly answered any question/requests that I have made. :thumbup:

I don't think you will go wrong with any of the two options (NST / ZPI). :clap:


Just don't go out and pay triple for one of those fancy JDM pulleys. :cool:

We are not 'in bed with them'. We have no ownership, legal ties or anything with them. We are a reseller of their products like we are of GReddy, HKS, AEM etc. Do we say that GREDDY, HKS OR AEM products are the best? No, I often bash 2 out of the 3 companies I just listed due to quality, craftsmanship or performance. We only sell and promote what we have tried, tested and beat the crap out of and it holds up 1000% to the abuse as advertised. NST's stuff has and it has withstood the test of time is what I am saying.

On a side note: You continue to blow everything I post out of context. Am I writing that off the wall? It seems it is only you that is misconstruing my posts. :iono:

Chino would you share a bit of that TON of knowledge...? :biggrin:

I don't know if this has been answered here before... but do you happen to know why NSt didn't underdrive their yaris pulley? Their Scion pulleys are underdrived. Just wanted to know if there's a reason for this. :thumbsup:

I can not speak for NST so I will not. I can assure you the ZPI product is of the best quality you will find anywhere. We have had some negative publicity around are company 99% of it stems from shipping issues. Our products have simply been more popular that our ability to make them. We have sold and delivered over a 1000 tC pulleys with no issue.

ZPIracing has eliminated past shipping issues by stocking up on item prior to their release. We do not do a preorder of any sort. We only take your money when we can ship your merchandise. This has virtually eliminated any and all issues with shipping, that is not to say we are perfect but we try to get as close as we can.

The ZPI Yaris pulley is a great mod; with as many as we have already sold this week it seems the market is welcoming us with open arms. We may even have to run an even better special to show we are serious about some Yaris performance!!

I can't recall ever having responded to you before. Maybe I have; I pay more attention to what's being said than who is saying it (with some exceptions, as some people have proven themselves especially stupid, so I disregard their posts entirely). But you don't ring any bells. Sorry if you think I'm following you around; I'm not.

I'll probably remember you NOW, though.

Okay, some of you still aren't convinced. Here is a couple more reasons.

First of all, weights...
ZPI pulley - 14.4 oz
NST pulley - 12.5 oz

Second of all, has anyone noticed that ZPI's pulleys don't come anodized? Hard anodizing does more than just make your pulley look pretty. It actually makes the pulley stronger. Aluminum is a rather soft metal by design, but hard anodized aluminum is stronger and will resist the sands of time better than untreated aluminum. ZPI will charge you 20 bucks extra to anodize your pulley. NST includes anodizing at no extra charge. They don't cut corners.

Sorry, I skipped right over that post.

Taken straight from the NST GB thread...

1. Regarding Light Weight pulleys vs Underdrive pulleys.

There is a ton of info about these concepts on our website and I will share just a tad with you here, you can look on our site or ask me on AIM and I can explain more. Also a lot of this info has been posted elsewhere on the internet by many of our customers and friends...

There are two benefits to NST pulleys. One is weight reduction, the other underdrive. Weight reduction leads to extra throttle response and a bit of HP and TQ being freed up and sent to the wheels. Underdriving from the crank pulley means sending less power to run the accessories, thus sending even more HP and TQ to the wheels.

The pulley we are offering you guys is of the first variety, it is an OEM diameter, lightweight crank pulley. We call this CR-Lite.

I will share some pics with you in the near future, but know this for now... The design of your crank case and your OEM crank pulley make it very difficult to design an underdrive crank pulley small enough to actually do any underdriving! If we could do more for you, we probably would, believe me.

Also, an underdrive crank pulley would slow your A/C and alternator by a tad, and many of you complain about your A/Cs being weak as they are. Most of you do not seem to want them any weaker.

90% of the time I am actually in favor of an underdrive crank pulley... but after doing some research I have come to the conclusion that for your Yaris a CR-Lite may actually be the best fit and best option.

My understanding is that a smaller crank pulley would not fit well on our car.

Charles,

Just a couple points here. I don't believe the NST pullies are HARD anodized. Correct me if I am wrong, I just hadn't seen that anywhere on the specs.

Anodizing is a chemical change on the surface of the alumnium. It does not actually make the metal stronger, just puts a tough wear resistant layer on the material. In hard anodizing, that layer is very similiar chemically to sapphire and it is more wear resistant than a regular anodized surface, or raw alumnium.

As I said above, the $5 extra for the anodized (hard or not) NST part is worth it in my book. It also seems the NST piece is a couple ounces lighter, which no one will ever notice one way or the other, but it is what it is.

I say make your own choice. Do the homwork and buy the one you want. Competition only heps us all out. I dont think either would benefit us that much. Im not a engineer so there is a fantastic chance im wrong.

Ashley, I am 99% sure I was told that these are in fact hard anodized, but I will double check that information.

When in doubt, it might be wise to do a quick search of the manufaturer's website for information :iono:

http://www.nonstoptuning.com/pKitToyYaris.htm

Here's an excerpt:

Each NST Yaris Kit is carefully crafted from 6061-T6 aircraft aluminum, tested and balanced to high tolerances. Every NST pulley is hard anodized for exceptional durability and is a great item for use at the track or on the street. Available in your choice of colors: Red, Blue, or Graphite Gray.

From ChinoCharle's DIY Thread:
OEM Toyota Pulley - 50.00 oz
ZPI pulley - 14.4 oz
NST pulley - 12.5 oz

The DIY has been edited to include this information. Thanks for your PATIENCE. :rolleyes: :bellyroll:

ZPI - 71.2% reduction
NST - 75% reduction

IMO with this small difference there should really be no tangible advantage between the two, especially when you consider other pulleys and the flywheel, so it should really be a matter of personal preference :smile:
