I’ll give you the factory warranty is important, but I’m pretty sure you modify this, Nissan will kick you and your Warranty to the curb.
Not much more bang for the buck....

It's not that simple. Here's some facts gleaned from Infiniti Q experiences during the VQ/VR transition:
-The 400HP is underrated. RWD cars are getting very close to rated crank HP at the wheels, this is proven by years of dyno comparisons. (AWD Q60 weighing 600+ pounds more than this Z can get to 60 in 4.4!)
-The VQ is a high-revving, moderate torque engine. It's actually better than most other NA designs, however the VQ is WAY down on OVERALL power. The torque from the VR30 is available from 1600-5600 revs, whereas what little torque the VQ makes is at a peak. The VR30 has a very broad power band, and makes more power all the time than a VQ. Also, think about driving at elevation, it'll be a revelation!
-The VR can be tuned way further per $ than a VQ. JB4 piggyback will give you a very noticeable kick in the pants. VQs need an optimistic butt-dyno.
-VR is smoother than VQ, which can seem agricultural (to me at least, but VQ exhaust sounds awesome) with the windows closed.
The VR is not perfect, the VQ will likely beat it out for long term reliability since it's not boosted, but for enthusiasts it's a WAYYY better engine.
