I was wondering the same thing.

Honestly though, I haven't really heard of much, if any, h6 manual swaps.

I just never understood why Subaru doesn't just make a manual h6 set-up. They could make it an option for the Legacy, especially now that the LGT is gone. Throw in the STI 6-speed and I'd buy one for sure!

I know mechanically its do-able. They were available overseas in a manual. I think the hurdle would be the TCM and the BIU. I think the BIU can be setup for a manual but the BUS system wants to see the TCM. I dont know if flashing the ECM would solve this or not. One of these days if the right deal comes along I will have to find out for myself.

I've got an H6 running with my stock forester 5 speed transmission right now, THis is using a UK spec b ECU to run the engine and a US manual transmission BUI. I know from the wiring diagrams service manual that "you" (as in subaru with the factory subaru select monitor) can program the BUI for pretty much whatever options you want even things like deleting the key in ignition chime.

If you are lucky and find a dealer willing to reprogram the BUI for a manual transmission you would just have to deal with the ECU There is a couple wires on the pinout schedule that are different like clutch switch etc, but very similar.
