You can't import a EG9 through SEVS as the 4DR EH? Was sold in Australia by Honda and just having a different powerplant [B16 v D16] isn't sufficent to pass the SEVS requirements.

So to import from JP, you need to go through personal import which requires you to prove ownership/usage for 1yr then you need to find someone to do the basic compliance and then registration.

Ie, not easy to do but doable, whether you want to do it for the EG9 though is a different story...
