It looks like we have threads popping up constantly with questions regarding pulleys.

So I decided to take some time and put up a good thread (FOR NST SCION tC II PULLEY DISCUSSION) in which we can cover most of the topics that normally come up, FAQs, along with user reviews and data. This last bit (user reviews and data) I feel are most important... so pulley owners, PLEASE take a few minutes out of your very busy days and post your experiences with us in this thread. I am very confident that your fellow board members will find your reviews very helpful.

First, I will post some general info regarding NST Pulleys, how they work, and why they help to free up power and torque.

Second, I will list some FAQs that have come up in past threads with info and answers.

Third, it is your job pulley owners, to post your first hand experiences, comments, and data with us.

Crank pulleys, attached to the outside of the crankshaft, are the source of power for a car's accessories. The alternator, power steering, water pump, and air conditioner are all belt driven units, attached to the crank pulley, that use horsepower from an engine to provide their own services. This draw of power by these accessories is called parasitic loss. NST Underdrive Crank Pulleys increase an engine's horsepower by reducing the power required to drive these external accessories. By replacing factory pulleys with CAREFULLY RESIZED / LIGHTENED units, some of the accessories are slowed enough so that their performance DOES NOT suffer, but just enough so that more horsepower is sent to the wheels and put to the ground. Where horsepower should be!

The R&D team at NST is dedicated to developing kits that provide great gains for track days and continue to deliver proper accessory output for everyday street use.

NST equipped cars do better on the track, benefit from increased accessory life on the street, and also deliver better mile-per-gallon fuel efficiency.


NST was the first company to design and develop pulleys for the Scion tC, and now offers more for the tC than all of our competition combined. We offer the most comprehensive line of pulleys for these cars, and we also have the ability to build custom pulleys for any custom application. NST offers more than 100 different pulleys for Honda, Nissan, Toyota, Lotus, Volkwagen, etc on www. NonStopTuning .com. When you buy from NST, you are buying from the leader in sport compact pulley development.


MIKE @ NST

1. Will I need to buy a new belt if I am using NST Pulleys?

A. The NST CR-Lite Crank Pulley for the 2011+ tC II, NST07158, is specifically designed for use with the OEM belt. You can use your OEM belt as long as you have a good, healthy, belt. Please remember that all belts are normal wear and tear items and should be replaced at roughly 50,000 miles.

2. Will/should NST Pulleys lead to any squeaking or noise from the belt?
A. A properly installed kit, along with the porper belt size, and a healthy belt, should NOT lead to any noise. Belts should be inspected from time to time and replaced at proper intervals. Belts should not be sprayed or cleaned with any chemicals. Dust or debry can be cleaned with a brush or a can of air.

3. Do NST Pulleys actually add HP/TQ?
A. NST Pulleys do not technically add power, they free up the power that the engine makes by way of great weight reduction and the slight underdriving of the accessories. The great weight reduction leads to improved HP and TQ curves in the low, mid, and high range... this is something very few bolt on modifications can do. These pulleys also improve throttle response and fuel economy, both of which can not be measured on a dyno but can definitely be seen on the road, or track.

4. Are there any independent dyno charts available to prove these claims?
A. Yes, there are several sources of independent dyno charts for NST Pulleys. Viewers should be careful to look for AREA UNDER THE CURVE when looking at these dyno charts. You can see improvements in low, mid, and high range HP and TQ. This is something most other bolt on modifications can not do...

5. Can NST Pulleys cause my engine to run lean?
A. The above pulleys can not, in any way, change the air/fuel ratio of a naturally aspirated or turbocharged engine... as pulleys have nothing to do with the flow of air, exhaust, or fuel. ECU reflashes, intakes, exhausts, or header systems are what normally affect air/fuel ratios.

6. Can I use the CR-LITE Crank Pulley on a supercharged or turbocharged tC?
A. The NST Crank Pulley can be used on any naturally aspirated, supercharged, or turbocharged tC.

7. What colors do you offer?
A. All NST Pulleys are HARD ANODIZED. This is the most durable method of anodizing in the industry, and very few brands are actually hard anodized. This process adds a hard layer to the outside of the aluminum and helps to make the pulley as durable as possible. Our main color is red, and we can offer custom colors on a special order basis.

8. How hard is installation? Can you provide tips or a DIY guide?
A. Installation should not be too difficult if you have previous experience with wrenching on your car. Chances are if you did your own intake, header, or exhaust, that you should be able to tackle this in a couple hours with the proper tools.

Ofcourse if you are the least bit hesitant, or uncomfortable with trying this yourself, you should seek the assistance of a trained professional. NST can not be held responsible in any way, shape, or form for any damage due to improper installation. DIY installations are performed entirely at the risk of you, the end user.



MIKE @ NST

This one deserves an entire book, but here goes...

Q. Will NST Pulleys lead to premature engine failure?

I cover this topic at least several times a month but I don't mind, I understand that your cars are a very large investment for all of you and I prefer that you be intelligent and informed about all your modifications. So here we go again... Please take a few minutes to read everything I have posted here, as I worked hard on trying to give you a good explanation on the topic...

In the past many engines were externally balanced. There was an external balancer attached to the outside of the engine, on the crank snout, used to balance the engine externally. The crank pulley in such engines would then be attached to this balancer. Removal of this balancer is a bad idea. These balancers were most often used on large (6 to 8) V shaped engines of the domestic muscle car era.

Take a look at any modern (1980s and beyond) Honda, Toyota, Nissan, or other japanese inline 4 and you will find no such balancer. These engines are all internally balanced, and this process has improved even further since the late 1990s. So the topic of a BALANCER does not apply here.

What you will find on many modern engines is a harmonic damper. This is a small rubber band, litterally less than 2mm, less than 1/8th of an inch, thick that is built into the crank pulley. OEM crank pulleys are often called DAMPERS. Try placing an order for a crank pulley at your dealer and your invoice will read damper. This rubber is used to absorb something called NVH, noise/vibration/harshness. Suffice it to say, this rubber is actually not very good at performing its intended purpose after as little as a few thousand miles. What happens to rubber after a couple years of humidity, weather, snow, rain, etc? It often becomes brittle, hard, and crunchy. Can something with these properties actually absorb vibrations very well?

Many many NST customers, including people on your own forums, have reported smoother running engines with NST pulleys. Especially at idle. How is this possible if the rubber is such a vital and super important piece??? Perhaps the rubber is not as important as it is cracked up to be???


Furthermore....


On the topic of the rubber damper, engine vibrations, or possible threats resulting from elimination of this rubber piece...

On a relatively understressed near stock motor with bolt ons or low amounts of boost like what most of the people on this forum probably run, a solid pulley will not have any life threatening consiquences. The factory pulley with a 2mm (less than a 1/8th inch) damper is primarily there for wide band NVH (noise vibration harshness) supression from the engine and driveline. Removing the damper and replacing it with a solid pulley may lead to minor addtional NVH but will not harm the engine. In fact, most people claim their engines seem to run smoother with NST pulleys.

The engineering reasons are that most modern engines have a short, strong crank with, a relatively high natural frequency. The dangerous second harmonic that can cause damage occurs at an rpm that this sort of engine will never see, in the area above 10,000 rpm. Even the stock damper is not tuned for attinuation at this sort of rpm so the argument is somewhat of a moot point.

Now weak engines that are pushing the limit with LOTS of revs, wimpy cranks, super long strokes, lots of boost and dwelling in the upper rpm ranges for long periods of time can benefit from a damper designed to deal with this sort of operation but our engine is not like this, and probably very few people with this motor on this forum push the envelope that hard. How many 2.0 Liter, 500HP, 12,000RPM motors do we have on these forums?

As far as I can tell, our engine has a strong and stiff bottom end that is well built for our intended use. It has an internaly balanced crankshaft which is less like to break due to torsional vibration.

There are a lot of Honda, Toyota, and Nissan guys who use underdrive crank pulleys in road racing series like NASA or SCCA. Road racing is much more punishing on an engine than other motorsports. The engine is subjected to run times lasting roughly 30 minutes with the engine always in the upper ranges of its rpm limit. One race weekend is the equivlent of hundreds of 1/4 mile passes. These guys would not use NST pulleys if they were not reliable.

NST sponsors the first ever wheel to wheel Scion tC NASA Road Race car. The same car is also very competitive in the Grand Am series and has factory backing from Toyota, Scion, and TRD. This car has been using pulleys from NST with great results since day one.

NST has sponsored several drift cars participating in the professional US drift series, Fromula Drift. Several of our cars have also competed in the Xtreme Drift Circuit and NOPI Drift series. To make things better, NST products are also used in autocross, time attack, and drag cars. These cars have been using NST pulleys with no issues of any kind for the past few seasons.

We could go on and on...

Is a solid crank pulley harmless to all engines? No it is not. As I said... small, super high reving engines, when modified way past the simple bolt on stages may have problems. These engines reach critcal harmonics, past the 10,000 rpm range, an rpm only reached by certain RACE engines.

A mildly modded inline six will most likely be fine but one subjected to high rpm for long periods of time (90% of its life) with lots of boost will probably suffer. In this case , the stock balancer/damper is probably not adequate either.

Some of the older american V8 engines are externaly balanced and it is critical not to use a solid hub pulley not designed for these applications, or damage to the engine could result. You will not find solid NST pulleys on our website for such engines.

Our engines and most around here do not fall into the above catagories. Rest assured that your engines will not blow up and die or have a reduced life in street and even racing use with these parts.

I would bet that every "expert" that tells you otherwise has little personal, practical, real world experience with the subject; as it applies in your case.

Again, I understand that your cars are a very large investment and that you depend on them as your daily means of transportation, so I do not take your questions personally. But please remember... No NST product is designed to cause you any harm or grief. Not all pulleys are created equal, and no other pulley is an NST pulley.

Well, I just finished installing the NST CR-lite Crank pulley. I would say the install was about a 3 on a scale of 1 to 10 (easiest to hardest). With that being said, you should use the proper tools (impact gun to remove and re-install the crank bolt, and gear puller to remove the pulley) to facilitate the job.

Initial impression: The NST pulley is significantly lighter tha the factory steel pulley. I was pleased with the overall quality of the NST pulley and the Skittles:). As soon as I finished the install, I took the car for a test drive. I was very pleased with the noticeable increase in performance, and had a big smile on my face when I came back in the house. I took my wife for a ride, and she could tell the difference as well (which is good because it was a Cristmas gift for her).

If anyone has questions about the install or needs help, please feel free to pm me or post it up.

I will be writing up my review in a few hours after I get a chance to take the car for a spin. This pulley is of the same high quality that NST normally produces. I run the NST pulley on my xD as well, it free'd up a lot of midrange power and it shows when I need to accelerate on the highways. So fired up to drive my tC with this installed!

i forgot to put the little wrist band in the picture but oh well! i should be having mine installed in the next few weeks although i doubt i will be able to wait that long.ill post my review as soon as soon as i get done test driving it.can not wait.

I got this pulley at scion expo an im glad i did felt the difference right away sry no pic i dont have one right now

BAM!

Is this still available? How much if I was able to.buy 3?

Why do you want 3??

Why do you want 3??

Couple guys in my local scikotics chapter would be interested fa sho!

True!

I have a question.

I read all of the posted material (except the section on premature engine failure) as well as a few articles on the NST website and am somewhat confused. From my understanding, it seems like the crank pulleys fall under three categories: underdrive, overdrive, and NST- "Lite." If I am not mistaken, this particular product falls under the "Lite" categorization, correct? Which pulley type is the best for overall horsepower gain? And does anyone know if NST plans on developing future pulleys for the TC2 (underdirve, overdrive)? Also, what do the aftermarket belts do vs the OEM ones?
Any clarification is appreciated, thanks :)

Good questions.

In some cases, NST Underdrive Crank Pulleys are very beneficial for naturally aspirated and turbocharged engines. In fact, we offer one for the first generation Scion tC. We also offer a CR-Lite for the first gen tC.

In the case of the second generation tC II, we offer a CR-Lite Crank Pulley... OEM diameter, same size as OEM. The design of the tC II pulley does not really allow us to make a smaller (underdrive) version. Our CR-Lite Crank Pulley has shown some very good gains on the dyno and in the real world. In fact, we have never seen any other four cylinder engine respond this well to a crank pulley. Very good news for tC II owners.

If you have not done so already, you can read about our dyno testing and watch the video at the following page on our blog: http://nonstoptuning.wordpress.com/2011/09/08/nonstoptuning-crank-pulley-dyno-testing-2nd-gen-2011-scion-tc/

And regarding belts... You can use your OEM belt with the CR-Lite that we offer for the tC II. You just need to make sure that your belt is in good shape. These belts need to be changed at the 40K to 50K mile mark.

Feel free to contact us by phone if you'd like to discuss further.


MIKE @ NST

Quick question...i think that our first gear is relatively short...for those who have it installed, have you noticed different mph of gear changer close to redline? Or that yer getting through the gears quicker. Mine is getting installed on Wednesday...just curious.

Thanks

i dont own an impact gun or a gear puller, is it still going to be a problem for me to do the install?

talked about it in my thread in the last 2 pages

what are the torque specs to re-install the bolt in the middle of the pulley, if you guys did torque it down

thanks

use this and a mallet to take off the bolt

wow thanks thats super helpful, im gonna borrow the gear puller from the mechanic at work lol make things easier on myself

id suggest having somebody help. i dont think its very easy to release the tension on the belt and take it off/put it on

plus its a good idea to have somebody keep the pulley in place while you are taking off the bolt/torquing it

My review, copied from my thread:
Ok, so I got the pulley installed yesterday(finally!) and the car is so much smoother! Which was a bit of a surprize to me. I ran the NST pulley in my xD and only noticed the hp increase, no real change in the drive itself. BUT on the tC2, I can shift smoother, rpms rise and fall smoother, the car feels much better. There is a noticeable increase in performance/speed at about 4,000rpm, all the way to redline. Which is much different from what I am used to in the pulley on the xD. The xD always felt like it gained a bunch of low end torque and died off in the upper range. The tC's upper range increase is much nicer. Also, Its only been a day of driving, but it seems as though I have gained some mpg too. I will update after a week or so of drivings. I am super happy with the pulley and NST.

^^
I have experienced all of that.

I got mine installed by a local mechanic this morning and was charged $84, which I thought was reasonable. So for all of you guys that don't want to do it yourself, use that as a baseline for what you may want to pay.

I was in and out in around 30 mins.

Quick question...i think that our first gear is relatively short...for those who have it installed, have you noticed different mph of gear changer close to redline? Or that yer getting through the gears quicker. Mine is getting installed on Wednesday...just curious.

This is what happened when we tested speeds on the dyno. As you can see, the MPH does not change, BUT it does require less time to achieve the same MPH in each gear.

In layman's terms... the Scion tC accelerates more quickly with the NST crank pulley :)

We decided to keep the NST garage open late tonight to install the NST CR-Lite Crank Pulley & a new set of coilovers on JTK2's tC. Yeah, both just happened!


MIKE @ NST

thats f*ck sexy!

except Josh was suppose to get purple coils! haha

So according to this graph our cars will go 0-60 in about 3sec with the pulley installed? Ummmm last time I checked the tc wasn't a supercar
haha! Pretty sure baseline on the 2011/12 tc is around 7sec...

can someone explain all this?

^^ If you actually look at the graph time starts at 0 but the speed starts at 50 mph on the x axis. So what the graph is saying is that roughly 3 seconds after you start accelerating from 50 mph you will hit 60 mph where as in our cars stock it would be closer to 4 seconds to accelerate the same amount.

^^ ah ha I knew there was something I was missing lol, thanks for clearing that up....it was late I was tired :lalala:

Correct. And to clear things up just a bit further...
We did this test in 4th gear, the closest to a 1 to 1 gear in the new tC.
We started at 50mph and went up to 120mph for each dyno run. What did the test show?

The tC required about 22 seconds to reach 120mph with the OEM pulley.
The tC required about 20 seconds to reach 120mph with the NST CR-Lite pulley.

That is a very noticeable increase in the car's ability to accelerate. If all other factors are kept constant, this will result in quicker 0-60 times, 1/8 mile, and 1/4 mile times. Will it reduce your 0-60 time by TWO seconds? Absolutely not. Will it reduce your 0-60 times if you keep other factors constant? Absolutely yes.

Thanks again, best of luck with all your projects!

Does installing a NST pulley have an effect on warranty?

^^^sheesh these among other parts have been and will continue to be in debate......warranty void....probably if your ____ blow ans this is installed....if not, prolly not....who the feck knows! lol

That's why he's asking. Why bother answering if you're just gonna say you don't know?

The answer is that no, it won't void your warranty unless Toyota can show that it was the cause of an issue.

Thanks. I ordered one today after doing some research. I am pretty easy on my new tC so I don't think I will have a problem. Just wanted a little more pep and the pulley seems like a nice mod for what I want.

Lol, I don't think I will be blowing it anytime soon. Just wondered if anyone experienced some warranty hassles. I guess this pulley is a fairly new mod for the 2nd gens so it may not have even been tested warranty wise.

got the pulley installed at a mechanics yesterday, today i seem to be leaking some oil or something, does this have to do wit the crank pulley?

Hey bud, sorry again to hear about your issue.

I spoke with you a couple times on the phone today, but wanted to address this here as well.
I would not want anyone to read this and possibly freak out.

IF your pulley is installed correctly and installed by a technician that has experience with TOYOTA/SCION cars, then there will be no issue. A properly installed crank pulley will never lead to leaks of any sort.

If you take a look at the center of the pulley you will see what we call a KEYWAY...

https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/417476_361938207169195_129204447109240_1263247_1338160394_n.jpg

THIS keyway must be lined up properly. Otherwise the KEY could be damaged and this could lead to a leak. There is also a seal on the backside where the pulley mounts to the crank. If this seal is damaged during installation, you may experience a leak.

As I suggested on the phone, I would suggest taking your car to a trained TOYOTA/SCION mechanic at a shop that has experience with these pulleys.

A properly installed crank pulley will NOT leak, wobble, etc.


Thanks again, best of luck with all your projects!


MIKE @ NST

Does installing a NST pulley have an effect on warranty?

Good question. And the answer really depends on your relationship with your dealer. We have seen a lot of dealerships service cars of ours, our customers, and friends who owned aftermarket parts including NST pulleys. We have also heard of certain dealerships that will try to void warranties for the smallest of modifications. So in a nutshell... it really depends on your dealership.

Technically speaking, the NST pulley DOES NOT change your air fuel ratio, does not change the way your ECU controls your car, it does not change your car's breathing (intake/exhaust) characteristics. There should be no reason why any of your warranty should be void as a result of this type of modification.

Finally, there is something called "the magnuson-moss warranty act" that basically states: A dealership can not void your warranty due to the use of any specific part UNLESS they can prove specifically that the part in question led to a particular failure. For example: You installed custom gears in your transmission, your trans failed, custom gears were the undisputed cause for the failure. Your transmission warranty is void.

For the record... we have never heard of any of our customer cars having warranty problems being blamed on NST pulleys.


MIKE @ NST

Thanks for the reply Mike. I'll be looking forward to receiving mine in a few weeks.

Finally got mine ordered.

Looks great!


MIKE @ NST

Ordered mine yesterday!!!!

There are now a couple of owners that have posted on their build threads that they have mentioned oil leaking from around the NST pulley they have installed on their 2nd Gen tCs.

You guys running these pulleys…can you keep a close eye out on your oil “consumption”? Take a look at your oil levels and post how many miles you’ve got on your car and how the oil level is doing. And keep reporting back. All of your feedback will either bring out this “problem” or put it to bed. Since this is a new product and still under development, I think this is invaluable information that should belong in this “comprehensive” thread.

The dealer I took it to to have my engine problem checked into, said the consumption wasn't an issue and went ahead and changed my seal and reinstalled my pulley. No issues with the aftermarket part. He said it would be a good idea to maybe reinstall the old pulley before I take it to my dealer to have my engine problem looked at. I believe I hit 4600 or 4700 miles yesterday.

I got 17k on mine
~400 miles with Pulley

Just checked oil level for the first time ever and it looks just fine

We definitely encourage all our customers to post feedback with us in this thread, both short and long term feedback. This is the reason for a comprehensive thread.

We have installed a good number of these pulleys here in the Houston area and we have never seen any issues with leaking in any of the Scion cars... be it the tC, xA, xB, xD, tC II, or any of the other Toyota cars that share these same engines.

PROPER INSTALLATION IS KEY HERE. Rubber seals can be damaged/punctured if proper care is not taken... whether they are behind the crank pulley or elsewhere on the engine. In some cases, Toyota even calls for the replacement of seals when things are opened up or taken apart. As I have shared with many of our customers, we strongly recommend going to a technician or a shop that has experience with pulley installations if you are not going to do the install on your own. You don't want a random person working on this sort of installation.

Thanks again, best of luck with all your projects everyone!

any update on the latest batch of pulleys? :pray:

Nvm it came today

http://s15.postimage.org/4db4o34kq/IMG568.jpg

Checked the pulley myself after first dealer said it wasnt an issue and that they retightned it. When checked I could loosen the bolt with my hand, thus that Had to be where the noise was coming from and those effers didn't even listen to me. So I tightened as much as I could and took it to MY dealer where they said yes it wasnt at torque spec and took care of it. I should have known better and torqued it myself...

just installed the bushing kit that came with the pulley SOOOOO much better when banging into gear ;) its very solid feel when you are all the way in gear cant wait till the pulley is done my mechanic wants 145$ gonna do it myself when the weather clears up will post up pics when done

Yeah man $145 is steep. The local shop took 2 mins assessing the install and was like yeah $84 no problem. If a shop quotes you anymore than 30-45 mins of labor, they are incompetent.

I didn't know a bushing kit came with it. Are they shift cable bushings?

just checked my pulley and no oil leaking..had my pulley on for about 1000 miles now

sorry for the confusion i ordered these at the same time i got the pulley they are cable bushings

I got ya. I also got some cable bushings. That with the TRD short shifter, the shifting experience is like a different car.

Now just waiting for my pulley to arrive. I ordered mine about five days after you so I am hoping it will come any day now.

If all goes according to plan will be installing sunday morning 8-)

i got the belt off no problem
but the bolt holding on the pulley itself wont crack lose i tried a 1/2inch drive breaker bar with and without extension on it also a electric impact gun rated for 230 ft/lbs torque

my car is manual and all the info i found online said you need to have the car in gear clutch released and brakes pressed in fully

tried all of these to get it off and was unsuccessful

any really wanna get this installed asap


thanks!

you're gonna need an air impact, 230 lbs./ft isn't going to cut it. The torque ratings on impacts are always inflated by manufacturers. An air impact on the other hand is generally gonna run a minimum of 350 in reverse, but most are higher...you just need a better tool or if you don't run air, Scion202 found a good way to manually get it off in his thread...something about a mallet and breaker bar I think.

Yea thanks I sent him a pm, problem is the pulley spins when using thar method even with brakes applied and gear engaged

yeah u need 2 ppl, one of my friends was holding the pulley in place with the other end of the black lug nut wrench that came with the car, he shoved it in the pulley opening

Or you just need to get the impact gun that Yuriy swears by :blah: haha

Got my pulley today. Installing tomorrow. :icon_biggrin:

Edit : Installed now. Definitely a little more pep and seems smoother.

guy i know has a shop near my house gonna help me take off the crank bolt for free this weekend

Pulley has been installed finally after about a month and I am thoroughly. Pleased with it. I was slightly disappointed by the rust on the inside of the pulley and the lack of communication. But I feel the wait was worth it. So overall I would recommend this to one of my friends. Thank you for the opportunity for the group buy and when I purchase a scion in the future I will use the NST pulley. Thank you again

Checked my oil the other day after at least around 5-600 miles. Completely full.

well i got the pulley on but now the 14mm tension is rounded out i dunno wtf happened to that lol picked up some gator grips heading out the the shop to get the belt back on its off by 1 thread, not having very good luck with this install

for anyone that's hesitant to do this its not that bad, breaker bar was much easier then the impact gun ( pull towards the bumper ) and when using the tension release i would recommend the serpentine belt tool for better leverage those a/c lines get in the way when using a socket or close ended wrench

update: gator grip socket wouldn't fit into that space, used a pry bar to release as much tension as possible pushed the belt a fraction over and then cranked the motor and shut off as soon as it started it resulted in the belt threading itself onto the last notch

After driving for a little while I'm now at around 23.3mpg where as before I was getting 19.9-21.2, definitely a gain in responsiveness and a much better feel when getting to higher rpms

You were getting 19MPG? Damnnn you beat on that thing

What do you have 35 inch tires and 4 wheel drive? I get better then that in my automatic driving 80 all the time. BUMMER DUDE!!

Still waiting for mine to come in.... I was told it should be shipped by the end of next week. Im anxiously awaiting its arrival.

Just don't get yourself too excited. It provides a nice mild pep...but nothing that is going to knock your socks off or anything.

Oh i know im not expecting anything crazy I just really love driving my car now so anything I do to it that will make it more fun is a plus to me.

Nothing wrong with that man I feel ya :)

So after about a month or so since my original problem with my pulley and taking it to dealer to torque down properly, the same rattling noise coming from the pulley area resurfaced this morning. Has anyone else heard a rattling noise or different sound coming from their engine compartment since installing this? I am seriously considering removing it if I keep on having problems. I will be taking car Back to dealer to have them check it again.

im really wanting to order this for my scion but i differently dont want to hear any rattling noise from my engine

Had mine installed for a few months now no oil leak and no rattle noise, rattle could be the plastic cover not installed correctly its four plastic body clips

Same here. Over 1000 miles driven since install and no issues.

thanks im probably goin to order mine thursday

thanks im probably goin to order mine thursday

just an FYI, it takes a while to get them. I ordered mine at the end of February and just cancelled my order because they wont have them until the end of April.

If theres something else you got your eye on, buy that, then come back to the pulley later.

why would it take almost 2 months for a pulley to get shipped to you

I guess after the group buy they must have decided to not make any more? I would keep them in stock

Am I the only one from the group buy that hasn't installed it? Lol....

Yea I gotta get on it.

Mine's being installed within a week or two, along with turbo, springs, etc. Wanted to do it all at once.

Thanks for the updates and the compliments ladies and gents. We appreciate it.


This pulley has been a VERY popular item for us this year. In fact, we've had a very hard time keeping it in stock and keeping up with production. We appreciate those who have pulleys on back-order with us and we do have an ETA of mid-late April for our next batch of pulleys. You can order now from our website or by phone to get on the list and take advantage of FREE shipping this month.

As always, I am available to handle your questions via email or phone call.


Thanks again everyone!!!


MIKE @ NST

I have spoken with NST over the phone and through email, and I can say they are great and will help you any way they can! I just got my pulley ordered yesterday, and I can't wait to get it installed!

Thank you sir! And we can't wait to get a pulley in your hands so you can get in on your car and post a review!


MIKE @ NST

I wish my pulley would come. I ordered it like 3 or 4 weeks ago:/

3-4 weeks isnt so bad. Ordered mine in late Feb. Im only impatient because I cant wait to get it on the car lol.

Your pulleys will be shipped out to you ASAP. Not a moment longer after they are ready. I hope you understand that building these things the right way, and testing them during the build process the right way, requires some time.

Thanks again, best of luck with all your projects everyone!


MIKE @ NST

The wait for a product that is 100% is well worth it. No one wants something rushed and not made to spec. I'm not impatient with NST just itching to get it and put it on the car. But I've learned that quality product is def worth the wait.

hey guys, i know NST made a pulley system for a supercharged engine for the TC1, is NST going to release a pulley for boosted engines or is this pulley fine to use on a turbo'd car?

The point of the pulley for the supercharged tC1 was to reduce the size of the pulley, which would make the s/c spin faster and produce more boost.

No s/c is avail for our car yet so it's not possible.

And turbo applications don't make their extra power from the belt system so there won't be a turbo specific pulley. NSTs current pulley will work fine for turbo applications.

wow completly wasnt thinking there... thanks for the reply.

Correct! The same pulley that we offer now would work for any n/a or turbo application. If a SC is released in the future, this same crank pulley will also work to provide better response and quicker acceleration!


MIKE @ NST

Finally ordered mine today! I'm so excited.

Another reported leaker...

Is it in stock??

I highly doubt it. However they should be done sometime soon..... Hopefully.

This was from way back though, I think he found out that it wasn't torqued down to 150 lb or whatever spec is.

Well…there have been several of them. So if the product is good then the installation must be bad. Do that many of you not follow instructions…or don’t have the tools to do a job properly and do it anyway?

We've sold a very large number of these pulleys since the release, and we have only heard of a few instances where a leak occurred... maybe 1% to 2% of all customers. Correct installation is key and when installed correctly, this pulley is good to go for the life of the car.

Feel free to read through the reviews and feedback of NST customers here on ScionLife. You'll find thousands of positive reviews from xA, xB, xB2, xD, tC, and tC2 owners right here on your own forums. Customers with well over 100,000+ miles of happy driving.

Our next batch of pulleys is scheduled for completion within the next couple weeks.


MIKE @ NST

Ordered mine about a month ago, can't wait to get it!

i think this an lightweight wheels and an intake are my next mods....in that order....

Installing my underdrive pulley on my xb2 next weekend (after finals) along with new pads all around. I bought it used (mistake), the keyslot is slightly mangled. I'm going to try to clean it up with a file and a bit of dremeling. It looks like the PO put it on and took it off using nothing but a hammer :facepalm:.

Hopefully no problems come from it, but if they do, I'll just pick up a new one from you guys!

paired with the fidanza flywheel I already have in here, I'm pretty excited to see the results!!

We decided to keep the NST garage open late tonight to install the NST CR-Lite Crank Pulley & a new set of coilovers on JTK2's tC. Yeah, both just happened!


MIKE @ NST

That's Awesome!!

^^
I have experienced all of that.

I got mine installed by a local mechanic this morning and was charged $84, which I thought was reasonable. So for all of you guys that don't want to do it yourself, use that as a baseline for what you may want to pay.

I was in and out in around 30 mins.

I figured it would be more wonder how much the dealer would charge lol

Good question. And the answer really depends on your relationship with your dealer. We have seen a lot of dealerships service cars of ours, our customers, and friends who owned aftermarket parts including NST pulleys. We have also heard of certain dealerships that will try to void warranties for the smallest of modifications. So in a nutshell... it really depends on your dealership.

Technically speaking, the NST pulley DOES NOT change your air fuel ratio, does not change the way your ECU controls your car, it does not change your car's breathing (intake/exhaust) characteristics. There should be no reason why any of your warranty should be void as a result of this type of modification.

Finally, there is something called "the magnuson-moss warranty act" that basically states: A dealership can not void your warranty due to the use of any specific part UNLESS they can prove specifically that the part in question led to a particular failure. For example: You installed custom gears in your transmission, your trans failed, custom gears were the undisputed cause for the failure. Your transmission warranty is void.

For the record... we have never heard of any of our customer cars having warranty problems being blamed on NST pulleys.


MIKE @ NST

Wish I had a TC to put one on. Seems like for the price its a very good addition to the car.

Y U NO DRIFT YESTERDAY???

@NST - I was told that the pulleys were going to be made at the end of April, any updates on them? I'm trying to avoid what happened with the group buy haha

Bro, I'm in the same situation. I ordered mine in mid-april and was told they would be done by the end of the month. I don't want to sound impatient...

I can wait, at 37 yrs old I have grown used to waiting. Lol, It always pays off if you want something worth a damn,. What colors will be in the next batch? I'm not picky, grey or red would suit me fine. I'd prefer the grey to keep it stealth, but the red is purty.
On the leaking issue, I'd have to say user error is probably the main culprit. I have botched a few simple installation jobs in my day.
I would like to know the exact width(thickness) of the stock pulley and NST's tolerance for the width. I imagine there is no room for error on the pulley's width.

I feel pretty confident that user error is the cause of the leaking problem. I ordered mine the first week of April and would love to know how long it is ACTUALLY gonna be until I recieve mine, because I as well as many others was told the end of April.

Has anyone recieved an update on their pulley? Still waiting for mine

No. Nothing. Not one word.

Finally got in contact with them. They said the pulleys have been pushed back to the end of May.

I was gonna start railing on how sad it is that you have that great part just sitting there....then I realized I have a set of beautiful coilovers sitting in a box right now. But for real, put the pulley on.....

Patience. When I ordered mine earlier this month, I was told that it wouldn't be shipping until the end of the month due to supply and demand. It'll get there man. Just hold out a little longer.

What you have to understand is that we ordered ours 2 and 3 months ago. The date they should be completed has been postponed a few times.

Ordered mine in Feb..... STILL nothing. I mean I understand the need to make sure they are machined correctly but how much longer do I need to wait. Every time I contact them the response is always that it will be shipped in a few weeks or the end of next month. How much longer do we all need to wait? I've tried calling but I can never get a hold of anyone.

They are waiting until enough people buy them so it's worth the time and money to make a batch.

Wow! I completely understand why you're so anxious to get your pulley. I'd feel the same way if I had to wait that long.
