There is a guy who used to post here that did a RHD conversion, as well and import and install the transtop. I think it took him like eleventy billion years to do it. It is A LOT of work.

Check out his profile on Team Sol's website

Also, the RWD idea is cool, but it would require an insane amount of cutting, custom fabrication and skill in those departments. The only Sol I know of that is RWD is a Sol owned by the Tuner in Japan called Top Fuel. They put a turbocharger B16 in the trunk of a Sol.
