vk: better engine management, shorter length, lighter block
rb: massive iron block that can handle lots of boost (but weighs a billion pounds)
in the end, you have to realize that truthfully, there is no replacement for displacement.

Get the VK. Even the LS motor would be better. There's way too many turboed VQ's, and quite a bit of RB's in the Z already, and going smaller in displacement seems kind of odd.

Wow whats with the hybrid swaps.. 2jzswap, Ls swap... wtf I think thats lame
. IMHO If you want to spend that money do turbo RB . If you want to turbo that VK good luck I wouldn't do it. RB ftmfw

i'm not looking for huge power really just a comfortable level like 500-600
i do have the cash to do what ever to the vq but sticking fix one to the two motors

3.5 vq 287hp
-2.6 rb 280 hp
0.9 litter larger than rb and 7 hp more than rb but not bad for smaller displacement

well umm... if you have plenty of money to do the swap, meaning funds arent really an issue? i would say go with the RB motor swap nice solid build and tune, and get the AWD installed in your car. i believe function tuned in VA can do this for you. How sexy would that be..... AWD rb 350z ^^ now thats something different. just motor is for pansies lol j/p
only reason i say this is because if your planning on a 500+ hp build... lol RWD just spins in first and second... awd you would have much more useable power

VK56DE
The VK56DE is a 5.6 L (5552 cc) version built in Decherd, TN. Bore is 98 mm (3.9 in) and stroke is 92 mm (3.6 in). Compression ratio 9.8:1.
Output is 305 hp (227 kW) at 4900 rpm with 375 to 390 ft·lbf (509-522 Nm) of torque at 3600 rpm. It has aluminum-alloy block and heads and low-friction molybdenum-coated pistons. The valvetrain is a dual overhead cam (DOHC). It has 4 valves per cylinder with microfinished camshafts and cast-iron cylinder liners for increased durability.
With cast iron cylinder liners it can take some more power with stock internals....raise the CR from 9.8 to 10.5 and a good tune for HP instead of torque and u can get ur 450 hp easy
and that engine runs regular....tuned for 91 or 93octane u can get 500 at the crank easy...
