I haven't managed to find out if the 5 and 6 speed boxes are the same so would take the same plate.

Lots to think about. I need to get the chassis started first before buying anything but obviously need to make decisions on running gear which dictate certain parts of the chassis.

The 231 6 speed will fit on a 192 Renesis engine; you'll have to look at the clutch/flywheel assembly to see what, if anything, you'll need to change there -http://www.rx8ownersclub.co.uk/forum/viewtopic.php?t=65599

If the RX8 box has anything like the shift quality of the NC MX5 box, then it is well worth it, the NC is a beautiful box to use.
