I have a T-56 with the works (still stock input/output):
Solid keys 1-4 gears - replaces stock stamped keys
Heavy duty steel 3-4 shift fork
1-2 modified shift fork - steel insert
New compressed carbon particle blocking rings
Bonze fork pads - replaces stock plastic pads
etc.

Have a ram adjustable master, powergrip clutch (with around 7k on it or so), steel flywheel, pro 5.0 and short stick.

I'm looking to make a trade with someone wanting to go M6. Not really sure on the crossmember and driveshaft on these setups, but willing to trade out on those too. Just want to get rid of the T-56 for the turbo setup and wanting to go to a taller gear to load the turbo. Please let me know if you're interested in a trade. PS - looking for a reverse manual w/brake.
