I have a clutch/flywheel combo with the adapter and flex plate to mate a 2JZ to a 300zx or 350Z transmission. I ran it in my car for a few months and it works great and is rated to hold 870 ft/lbs of torque. I paid $1100 for this combo and asking $750 shipped with just over 1000 miles on it all.
The kit was purchased from Collins adapters and is a Powertrain Technologies clutch.
