4AGE to 6-Speed gearbox adapters (Altezza/MX5/RX8)

Proposed part: Who might be interested in an adapter to fit a 6-speed Aisin AZ6 gearbox onto a 7 / 4age engine?

What I am looking to produce and am currently investigating is an adapter that bolts to the block and then the original 4age starter motor and the new gearbox bolts to it without modification. A spare block has already been dialed up for the different bolt and locating dowel co-ordinates. Next up are the front halfs.

I wish for us to begin with the gearbox that's normally behind the 3SGE BEAMS powered Altezza. However pending on how things work out I would look at something to suit the Mazda MX5 and RX8 variants as well.

Price: As a rough guess these adapters might be around $400 with bolts, from there I could offer extras like transmission mounts, spigot bearing spacers, concentric slave cylinders and so on.

Wanted: Any of three Aisin gearboxs dead or alive - Altezza, MX5 or RX8. Send me a message if you have something to sell.
