never compare a complete engine price in Japan to whatever you can do with your money elsewhere in the world.
Nismo Omori Factory regularly sells rebuilt RB26 engines for anywhere from $20-65k+ USD. The engine pricing is anywhere from a basic rebuild to about 500+WHP mods, but for the money you spend you're better off getting something from somewhere else and build your own.
However, what these shops do is provide a complete turnkey service for the customer in Japan. The engine may be orderable for an overseas customer, but 1) there is an engine deposit/core charge required, and 2) it's meant as a "drop off your car at the shop and pick it up weeks later" type of service.
Omori Factory is one of those places where if I lived in Japan and owned a GT-R, I would love to have them work on my car.

An example are these 3 from Jan 2017:
Left to right, the prices are JPY 4,800,000 // JPY 7,150,000 // JPY 4,300,000.
None of them are more than 500WHP as-is. All 3 still keep the stock twin turbo config with upgraded N1 units.... which still suck.
Omori Factory sells a lot of these in Japan every year.
