Yes, with fuel return system, bigger injectors, oil cooler and proper UpRev remap, as provided in the first post.
Providing your engine was looked after and not oil starved, with 248.298 miles on it, of course :lol:
425-450bhp with this kit as it has proper components that won't maximise on the dyno like other options I've seen offered here, eg better quality and bigger injectors and fuel pump, oil cooler etc.
This is the best option for the 350z, safe, reliable, powerful.
