I've read in a different forum (NASIOC) that they have successfully added a turbo (AVO turboworld) to an XV with an FB20. has anyone tried to add a turbo for the FB20 foresters? or any link to any site that has successfully done it. I've also heard of a supercharger made by raptor superchargers that is bolt in to an XV with the FB20. has anyone looked into this? thanks!
