I think with a lot of time, trial and error, and money. 500whp is doable. I think you would need to ditch the VVEL and go to a traditional intake cam though. And obviously a Standalone EMS. I also think it would require race gas to reach that number as well.

There was a 350z in Japan (limited run) that revved to above 8k but they dropped the displacement from 3.5 to 3.3. It was designed to alter the powerband for track setups.
Now onto the OP, you must remove the ideas from American V8 motors when dealing with the JDM engines. The Japanese prefer smaller displacement cars which rev higher and occasionally throw turbo(s) on. Now this is great for certain things, but NA power it is very limited and even with engine upgrades you are very restricted. Also, this motor is very 'tech' oriented which is also a negative as just throwing upgrades at the motor will not directly lead to results.
