Tested: 04 VQ35 IM on 98 VQ30
Hello
This weekend I tried to put the intake manifold from an 04 Maxima onto my 97 Maxima engine. The lower manifold will bolt on just fine and appears to form a tight seal to the heads however, the holes for the injectors are different. If you want to use the 04 Maxima lower IM you will need to dremel the injector holes on your VQ30 heads slightly, not much, but some. The upper intake manifold hit the coil packs as well but that could probably be solved with a little effort. I gave up because of other issues with my particular application.
Of course you will need to use a top feed fuel rail and top feed injectors. The 04 fuel rail is a returnless type and is probably not the best way to go. The 00 VQ30 uses a top feed returnable type, that is what I was going to use but gave up before I got the chance.
Hope this helps someone,
allen
