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?

its fine

 

^thanks

 

use a 24" breaker bar....your crank pulley will come off.

 

isnt the whole point to lose 5lbs in the crank pully?

 

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.

 

what do you mean by replace the belts?

 

Thanks for info, will try my next day off.

 

i kno, i ended up just installed idle/radi pullys...

 

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.

 

Edit: i took it to local shop, still didn't come off. I guess my car loves stock crank pully lol..

 

Fixed

 

 

How did you manage to change the Alternater pulley?

 

bolts was easy. Just a crank pully.

 

you didn't have to remove the alternator?

 

I hear it's a reall SOB to get the old pulley's off kinda of like z headers.. Is this really worth it?

 

I didn't

i got an idea from here, also from other member's pictures.

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
