I am interested in that too, specially as i live in brum. Could be the only 4 door, but i know of 2 3 door EK type R conversions, and a couple of JDM EK CTR's as well.
If your interested they are members of
www.honda-R.org have a look at the forum and join if your interested, or come over to the stand at JAE in billing, northampton next weekend, always good to get more honda owners, especially non R cars.
