i believe it is. i know sean at sam just installed a 997 turbo transmission into his 996 no issues. i don't think the gt2 is any different
might be cheaper to just install the gt2 gears into the 996 trans housing though

Saw your PM, but thought I would post here.
Yes - the 997 gt2 box fits. It's identical to the 996 gt2 gearbox externally. As such you will need to do the following:
1) gt2 slave setup. This bolts directly to the opposite side of the gear box so you will need the gt2 clutch fork. This doesn't come with a new gear box
2) Oil cooler. The gt2 box has an external oil cooler. You can either purchase the water connection lines or, as I did clamp the lines, and then cut them and insert a brass t-fitting. From the t fitting run a line to the oil cooler, and then out of the oil cooler into the water line. This does what the oem lines do.
3) remove the vacuum actuated switch for water flow. The gt2 uses a temp sensor to open a valve to let the water flow at a certain temp. Just like a thermostat, this lets the box warm up quicker. The feedback I got from guys with cup cars is that removing this simplifies the setup and removes the potential for a vacuum leak. Water runs through the cooler at all times.

Your good to go then.
One thing I would check before putting the gear box is is the lsd. They are pretty weak from the factory and do not have much preload and what little preload there is falls of pretty quick. Mine is almost and open diff now and I have maybe 5k on a brand new gearbox with no track days.
I wish I had opened it up and had guard increase the preload from new.
