Hey guys just a quick one. My crank pulley on my '98 wrx is making a horrible noise and been told it needs to be replaced asap. I have recently undergone an engine swap, from an ej20 to an ej22. The pulley on the ej20 is still good, so I'm wondering if it would fit the 22, save me buying a brand new one. If anyone knows or could point me in the right direction, that would be great.

Or.. do i really need to buy a brand new one? If so, genuine?

Thanks, Sam
