The Japanese S14 and S15 turbo are basically the same. Both the compressor and exhaust housings are the same. The compressor and exhaust wheels are the same specs. The difference is that the S14 exhaust wheel is not made of the same material as the S15 exhaust wheel. I can not remember the materials, but they are NOT ceramic, they are steel alloys.
The S14 turbo in Australia is not ball bearing from what I have been told. The S15 in Australia is ball bearing though.
