The thread appears to have cooled off a bit, so this might be a good time for an initial review of the NST pulleys post install.
Installation: I had the install done at Hills Garage (highly recommended shop) in Baltimore by Frank (Nissan Master Technician) and Suzanne; the install went as smooth as baby skin. I was worried about fitment, sanding issues or having to take the alternator out but luckily none of that happened. Install took a little over an hour and the car was ready to be picked up.
Parts: I went for the kit with the 2 pulleys and belt stock grayish finish, the parts looked great and very clean plus Mike@NST did provide a fantastic customer service along the way, kudos to you Mike.
Driving Review: The pulley kit is a great replacement for the vehicle so far, Triple nailed it when he stated something in his review about the car feeling smoother and having a better flow overall. Now compared to the stock pulleys, the NST pulley give a much better throttle and once again smoothness while switching gears and cruising. It may be just me but I feel like there is a power gain from the 3rd gear and above.
Overall, would I recommend the pulley kit so far based on the initial miles... absolutely yes. Will keep all posted on kit experience as mileage goes up.
