What is the deference in the Vq30 and the VQ35? Other thin the displacement.. Is the block the same and its just the stroke is more on the 3.5 or is it a bigger bore? I want to make my 3.0 in to a 3.5. Rather do that then get a new 3.5!!
The 3.5L had variable timing control camshafts, for starters. The intake was differant, the stroke was differant, harness and ECM, to name a few things. You'd be better off trying to find a 3.5L Maxima or Altima in a junkyard (good luck) than trying to convert the 3.0L. You can do quite a bit to the 3.0L and depending on what you're going after, it may be more beneficial to use the 3.0L.
Replace your 3.0 with a 3.5; a good condition junkyard 3.5 is only US$1000 or so, which is far cheaper than the labor and parts involved to bore and stroke a 3.0L to 3.5L-- hell I don't even think you can get a 3.0L block out to more than 3.3L or so with factory VQ parts (VQ20, VQ25, VQ30, VQ35, VQ40....)...
