I’ll offer up my .02 real fast since I had these put on last Saturday. Woke up around 8:00 am and set out for the short 3 hour trip to Houston to pick up the parts and have them installed. I wanted the install done by them since these were their parts and all. On the way out though, I pulled over and took a quick video of how well the car reved up in neutral after it had time to get up to operating temperatures. Did a few quick pulls before continuing on… The things I noted are: -Pulleys did free up some power. -No change in sound from the engine or anything. Everything sounds just fine. -The stock pulleys are HEAVY!!!! My goodness they were heavy in comparison… -Revmatching is a bit easier. -IMPROVED GAS MILEAGE!!!!!! I want to call special attention to this last one because I really feel that it is often overlooked when people discuss modificatioins to any vehicle and it really frustrates me because I am a stickler for maximizing the efficiency of a system, in this case the engine. When I set out Saturday morning and got on the open road I reset the in car instrument that records average MPH and average MPG and drove very conservatively, trying to maximize my MPG. I originally planned to fill back up once I got to Houston and get a hard figure, but they unplugged my battery and it erased my trip numbers (o the joys of the digital age). However, the in car instrument showed a solid 27 mpg for most of the trip. Just for reference, the stated highway mileage is 26 mpg. Post pulley install, I filled back up, reset the in car instrument and hit the open highway driving the same way. On the return trip I recorded a solid 29 mpg and verified it after getting home and filling the tank back up. That is a solid 2 mpg increase or a 7.4% increase in gas mileage which is IMHO, pretty substantial. I will be keeping a close eye on the coming weeks to see if I get similar results under normal driving conditions. As an aside, there was a section of driving where the speed limit was 55 mph for probably 5 minutes of time with pretty even terrain. Before the pulleys, I was seeing around 28.5mpg and after the pulleys I was seeing around 31 mpg, or about 9% increase in mpg.

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 had my pulleys installed ~10k mi. Currently about to hit 55k (N/A), and zero problems from either crank/alternator pulleys.

That’s my car in the video years ago! 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!

Pulleys are in!! Nissan Master Tech “Chuck” did a great job. He said he lowered the front sway bar to access them. He had it done in about an hour (that included a ester oil change)….As far as Reviews, Chuck at Nissan said everything went smooth and he really liked the quality of the pulleys….those factory pulleys feel like 10lb weights!!! Drove 5 miles home and got on it twice and seem to feel a bit quicker revs in 1st, 2nd, and 3rd….Also some others complained about wine or noise….I could hear nothing and seems just as smooth as factory or better…(maybe Nissan Techs have a special sheet on how to install and remove pulleys?) Overall im very pleased!!!
