Plus for the cost of $30k (new) or $15k-$18k (used) it isn't that great of a deal. For that sort of money there are plenty of other options, including building up the FA20 to get all the power you could want (maybe not 400 but 300 could be possible with the right parts). If RPM's are your thing then maybe a Mazda rotary would be more to your liking.
I think that's what you're not getting, it's a naturally aspirated engine that makes 400hp or 500hp or something, there's no need to discuss it further. With stock BRZ gearing because the displacement is 40% higher you will have probably around 30% more torque all the time. With 5:1 gears the 12000rpm redline or whatever still presents a huge increase in top speed per gear + much more acceleration available.

The FA20 pretty much can't hit those power levels no matter what you do to it while keeping NA. Sure superchargers add great power but this engine not only adds power, it probably slashes weight off the front end too, which is important.
