VG30DE vs VQ30DE? 300ZX motor top-end swap..

I'm wanting to do an NA build-up on my '95 Maxima. From what I've gathered, it has the VQ30DE motor. Are the internals in this motor interchangable with the internals of the VG30DE (300zx motor)?

I have a friend with a used, still strong running 300zx motor he's willing to part with for cheap and I'd like to basically slap the top end of it onto a re-built bottom end of my motor. Will this work?

More specifically, is the block the same (ie. heads and pistons/rods etc a direct swap?)

Any info much appreciated

The VG and the VQ have no common internal parts. To my knowledge there is not a single part that will bolt up. The only thing that we can use is the injectors (only for 95-96 Zs) and the MAF if boosted. There are also some brake components but nothing as far as the engine. The 350Z has a lot more parts that we can use regarding the engine. The 89-94 maximas have the VE30DE and the VG30E so they have more parts in common with the Z31 and Z32.

like the other one.
