I was able to find out from friends of mine who are on K20 and DC5 forums. I've also been doing a little questioning on honda-tech as well.
I recently bought a crashed 2000 JDM ITRx. From what I gather, it's the rarest out there. They are yellow with yellow Recaro SRDs and even come with a yellow ignition key. The one I bought is #150. Sad thing is, it was brought in used, so somebody in Japan swapped the interior for the usual black with red stitching SRD package.
I have found out that I will need a bracket for the front DC5R calipers and simply install the DC2R 5 lug conversion. I will try to document the conversion on here since nobody has done it before.
Just to give you an idea of the size of the Cayman Islands, every person living here could fit into Tampa Bay stadium with seats left available.
