I've been looking into this and RX8 6 speeds are plentiful and very cheap. How similar/dissimilar is the RX8 6 speed from the J160?
Is it possible to install the gear lever kit on the RX8 gearbox?
RX8 gearbox seems like the best way to go for the North American market. They are as cheap as $400 USD on ebay buy it now.

The RX8 gearbox is nearly the same as the Miata version... the only real difference is the tail housing on the RX8 is shorter, and the shifter placement makes modifying the tunnel almost the same job as it is for the J160 version.

So... to answer the first part of your question... as long as the RX8 trans looks like the one in the photo... YES , our adapter will fit it. To answer your second question, the shifter kit we manufacture only fits the J160 because the J160 has an area we can mount the shifter too (the original shifter mounting holes). The tail housing for the RX8 is different, and so our shifter doesn't fit...
With that said... the RX8 shifter location will be similar placement as it is in my car... the tunnel will need to be modified, but overall it should work!
LEEN plugs in their specifics, and out pop finished components. I believe the longest wait do far was a client who waited 6 weeks.
