Well, it all comes down to your budget. You still haven't told us how much you are prepared to spend.

You could easily buy a kit right here in Aus. Yes there are lots of good turbo kits in the US but why import from there when you can buy one in your own backyard.

There are so many workshops doing turbo conversions for Honda's at the moment i'm sure you could find the right kit at the right price. Online Performance and Croydon in Sydney have built some quick turbo Honda's. If you want a custom fabricated turbo kit go see ACS Engineering in Melbourne (PM A.C.S. Drag) on here and he can help you out.

It all comes down to budget though. How much can you spend? And where are you from?
