Default Pulleys ???

I bought a used ur crank pullys from one member here, i installed the idler and alternator, but stup*d crank pully didn't come off, so i decided just leave it like that.

here is my question, is that ok to just use lightweight idler and alternator with stock crank pully? or should i replace back to stock?

The crank pulley is a bear to get off. I had to use a breaker bar and a 3 foot section of aluminum pipe from Home Depot to get mine off. If you do go for it you will need to replace the belts.

I have a UR crank pulley and lightweight flywheel and the car revs up a lot faster then it does stock, really makes a difference. The rev action at idle when you blip the throttle is much faster than before.

Smaller pulley uses a shorter belt.

Old pulley
I just took them off,
http://www.unorthodoxracing.com/inst.../04100150_.pdf
i got an idea from here, also from other member's pictures.
You can find more DIY from G35driver.com

worth it?
After i installed pulleys, i realized that 'it's NOT that worthy for $'. But i got it for good deal + time to change my belts anyway. Lot of people said that they felt from their butt dyno, but my butt dyno felt more power from MD's spacer lol
