It's possible, but then why????? :shock:
When you go turbo, your oil filter will then be underneath & behind the turbo. Have any idea how much fun it is to remove a oil filter when your turbo is hot????
This is why some peeps have the oil filter relocation kits done when they go turbo.... Less hassle dealing w/ removing the oil filter when the turbo is warm.
And it will also depend on your IC pipe routing. Which might make it more of a pain to try & remove the filter from the top.
