The time has come for the true test of my Google-fu - the internet says all of this will bolt together and fit in the Impreza.

And holy crap it does fit... at least close enough that we can brute force it.

Anyway, to recap: H6 out of liberty, onto GDA WRX crossmember, flex plate off, flywheel and clutch on, gearbox attached, all then bolted into Impreza. And we only ruined one engine mount doing it.

Subaru miracles from this installment include: H6 drops onto WRX crossmember using stock H6 mounts, manual gearbox bolts straight up to H6, 6 speed gearbox mount bolt-holes exist and are threaded, ej18 starter motor appears to fit(!), both the H6 and the 6-speed gearbox fit in the impreza (although we did have to remove all of the brackets on the gearbox).

Not seen in pictures: We also swapped the drive-by-wire Liberty accelerator pedal (which will require a new mounting hole in the firewall) and Liberty ABS module (which will need a new mount bracket) including all hydraulic hard lines, all of which should mean that we can have traction and stability control!
