My B18C came with a 3 belt crank pulley. I only need one belt, to run my alternator.
Is there a safe(rubber damped) alternative that won't cost $600 like an ATI?
Maybe one from another Honda/Acura?
Anyone have any luck cutting down their stock one?

 

You cannot cut down the stock one, it will take it out of balance.

 

Keep the OEM pulley, no reason to get rid of it, there are guys out there making plenty of power with it.

I had a CTR N1 pulley on my last motor and it is the likely cause of eating up the oil pump, as they are known to do.

OEM or FluidAmpr or equivalent

 

That is exactly why I asked for a "safe alternative". No N1 for me
This engine is going into a CRX so the extra clearance would be helpful. My pulley is also showing signs of starting to delaminate, so it would be a good time to put something else on.
