Pretty sure getting OEM parts for the RB is still a pain in the buttocks stateside, or at least compared to a 2J.
KA's also have some inherent design flaws from the factory, and I must say that the SR seems to be more well engineered, at least for boost. It's more of a matter of opinion at this point though. My major pet Peeve with KA's is that they don't like to rev as well as SR's, which I mentioned before, and it's due in part to the fact that the KA does not have a fully balanced crank from the factory, so the motors can do really interesting things in the higher RPM range.
