YES!! I finally installed my unorthodox pulleys.
I thought I had to take my radiator out, but I didnt have to, but I took my alternator inorder to replace my alterntor pulley. Other things are piece of cake.
WEight wise, stock ones are WAY havier than the unorthodox. There are no squeeq sound ( i got belts too) what so ever, I really love it.
Performance wise, I can defnitely feel the difference from high rpm around 3 and above. I installed it from nissan dealer. They charged me 125.
THanks to concept z ( coz) i will post up some pics later today

 

Z,

Please post the pix as soon as you can! There are a lot of us anxious to see the results. BTW, how many pullies did you swap out?

Thanks!

Q

 

I did all 3 with belts. Installation wasnt that hard. You could ask nissan dealer guys to do it for around 120 dollars. They do a good job on it. If someone say you need to take your radiator out, than he or she is bulls@itting. That way they can rip you off like crazy. Infiniti dealer quote me 450 dollars to install my pulley. Only thing you need to take out is an alternator to make sure you torque them right.
It is the best mod with under 400 dollars budget. I can defnitely feel the torque gain on this. No weird noises so far. I had them for about 3 weeks now. Make sure you get the belt with the pulleys. Ask COz at concept Z, he will take care of it.
