i'm not an expert on this but i was told thats a popular conversion though you should buy a kit to make things easier, however i dont know where you would find the kit however i belive it was maxiwesty.com did a comparison of the motors a few years back and found the v6 nissan maxima motor to be better suited to the task yes the 911 motors faster but for perspective go on any parts stores website and compare say headgaskets for a 911 motor then for a v6 maxima motor. personally im going for the 2.3l subaru in my 84 vanagon
