"Pulley installed. Took maybe thirty minutes? And that's with my minimal mechanical experience. All of my friends drive Hondas and I'm the only Hyundai so this whole car has definitely been a learning experience for me. I can notice a slight increase in torque, definitely feels a little more peppy, and the **** dyno likes. Small gains add up, well worth the buy.

"Based from experience these pulleys are well worth the money. Does everything it says it does. Easy installation (depending on car and mechanical knowledge). I've had the NST Pulley on my tC for about 4 years/40k miles and that was with about 20k miles of having it turbo charged. After that I bought some for my 370z and what a difference it makes! When installing correctly and using NST products you won't have any issues!"
"1JZ swapped 240SX NST cam gears NST pulley kit. Great items. Easy to install and they work great. NST has provided me with these awesome parts. Once I start assembly of my 2JZ I will purchase another set. Thanks again NST."
"This kit was purchased for my 09 Scion tC and after 85k on the car. I have not had any issues and like it states it does release some hp and tq as you could feel it from 2-4k RPMs. Great kit for the price.

"Ok, got my oil changed AND had my NST crank pulley and alternator pulley installed at the same time. First of all, let me say that the pieces look great. They are SO much lighter than the stock units and the quality looks fantastic. I had a mobile mechanic come by to do it. He used to work at an Infiniti dealership so he didn't have too much of a problem installing. He did say that pulling the stock alternator pulley off was a **** from underneath, but he got the whole thing done in about an hour. Driving impressions: The car definitely revs more freely and seems to accelerate quite well. I don't know if it's just me, but it seems that there is less vibration than before also. I was expecting the opposite, but was happily surprised that the car felt smoother overall. This was the first mod done to the car and I'm happy that I did it. Once I drive it more, I'll post any other impressions that come up. All in all I give NST a big thumbs up for great service and information as well as supplying a quality product."
"I had this full pulley kit installed on my wife's 2006 G35 coupe and instantly noticed a difference in its drivability. It now has quicker throttle response, better acceleration, smoother movement throughout the power band and is overall more fun to drive. Very impressed with the kit. The car has always had power, but more is always better. Wishing we had installed this kit a long time ago. Props to NST for making a quality set up that is easy on the pocketbook."
"I'd like to weigh in on my experience with your pulley for the tc2. I have had mine installed for 140,000 out of my cars 200,000 miles and it has been great! no squeaks, no leaks, no shredded belt, it does exactly as you claim. Hell the only reason I remember I installed the pulley any more is when I pop my hood to check/change my oil i see your shiny red crank pulley. Great product NST, and if i ever purchase a pulley or pulleys for any of my future vehicles you guys will be my first search."
"2013 Toyota Corolla s. Looks good. Arrived in a timely manner. I did notice a some extra pep in my step, so it did free up some power. Nothing too crazy, but significant. I already have the K&N short ram intake, DC sport headers, Borla catback exhaust, and a Monkey wrench throttle body spacer. Every little bit counts. The only reason I didn't give it five stars is because It wasn't really compatible with my OEM belt. It was too lose, but I just bought a smaller belt and problem solved. Great product."
"I have had about 300 miles on this crank pulley and it really helps out my 2014 CVT Corolla. I used the same belt, just had to tighten it all the way. Really helps out in acceleration. Car revs faster. No issues with AC A must in combination with CAI,header, exhaust,and Pedal Commander. Thanks NST!"
"Shape, quality, and material were great. I do wish it were a little heavier, but that is personal preference."
"Ordered, received, and installed pulleys from Nonstop Tuning (NST). Pulleys were installed for approximately 8,000 miles before 2 of them failed. Initial contact made 9/14/2016 regarding the failed pulleys, at which time I was asked to ship them back. Pulleys shipped to NST on 9/15/2016 and on 10/3/2016 NST contacted me to say the bearings were bad, they had a bad batch and were working on a solution.
-Skip to January 16, 2017 when I next made contact regarding any updates...... no reply
-Skip to February 3, 2017 when I again made contact regarding an update; reply came on 2/7/2017 "We have been working on this issue and we believe to be getting closer to a good solution. We expect to have a final update for everyone in late Feb / early Mar."
-No updates provided.....
-Skip to July 11, 2017 Made contact again regarding an update; reply came on 8/16/2017 "We apologize for the delay on this matter. The entire process of redesign, testing, and then manufacturing on our idler/tensioner kit has been ongoing. This is a process that has taken longer than we would like, but it is a project that has been ongoing and has not been forgotten. We expect to move forward with manufacturing/production over the next couple months and all outstanding cases/orders are at the top of our priority list.
We continue to ask for your patience and support and will update you ASAP."
-ASAP is apparently never because there weren't any updates between 8/16/2017 and now, despite making contact with them again on 3/9/2018.
Maybe they're working to resolve the issue, maybe they're not. I have no idea because their communication is about as reliable as their pulleys.
Spend your hard earned money elsewhere. "
"Weight, heft, and feel are superb. Absolutely love the way my shifts feel with the new knob. Personally, I would prefer a little bit more of a roundness to the top, but it's great as is. It does get a little warm when left in the sun, but not nearly as much as my leather seats"
"Extremely happy with these pulleys. Installed in about an hour, fitment is perfect. Anodized purple really pops. Overall an easy and cheaper mod to free up as much power as possible.

"Small team of enthusiasts offering quality products at unbeatable prices. "
"They took my money and months later still "waiting to ship" will not respond to messages on website or other media platforms or phone and email. I want a refund. "
