I found a JDM EVO VIII for sale. It has the 6-speed tranny, of course, but what else is different? The JDM evo in question is damaged but might be worth getting...

It's in the "parts" section of the site, not sure if that means anything.
Scroll to near bottom under "Other performance items for sale" and click on "JDM EVO 8 with 6 spd trans." http://modifiedcartrader.com/

Comments, concerns will be appreciated...

 

AYC and ACD along with the 6-speed ..

 

That would be really awesome to have, but it does look like it might have chassis damage, which would make it totalled in almost all cases. If you can find a body shop who can do it, that would be sweet!

 

Probably RHD (right hand drive)?

 

It is RHD.
