Is it possible to use AEM pullies on a JRSC'd car and pick up horse power from it?

 

You can use the AEM pulleys with the JRSC. It will require using a different main accessory belt. The belt that comes with the JRSC is 6PK1930. You will need 6PK1970 to fit the AEM alternator pulley. The AEM power steering pulley will use the same belt that came with the pulleys.
