you have 3 options! 1. go custom - cheapest way to do it and can get it to your own custom spec 2. buy a buddy club spec 1 system for your n/a from japan, usually can be found and ordered via RHD Japan 3. Look about on the internet and see if you can find a rare or cheaper n/a system of the japan yahoo auctions etc and get a buyer over there to purchase it for you and get it shipped over. The last 2 will be quite expensive so probs best going custom mate.
