Or if you shop right you can even find a G96/96 with a cooler for that kind of money. And both of them give you the beefier ring and pinion.
Availability of these core GT3 boxes has gotten so good that it just doesn't make sense to put more than $4000-5000 into a G50/20, assuming that you already own the gearbox as a core to build on. If you've actually got to go out and buy a G50/20 core AND build it up, it makes no sense to me at all.
For comparison, the G96/90 ratios are as follows:
9:31 R/P
11:42
20:43
25:39
33:40
37:36
39:32
If you chart it, 1,2,3 give similar numbers to the above referenced chart and then on 4,5,6 the gap opens up a bit. Even if you buy a shorter 4th and 5th for the GT3 box and are into it for $10,000 that's a lot more gearbox than the same money buys you in a G50/20.

Matt, I used to say the same until it was pointed out to me(I think by Chris Cervelli, but my memeory is failing rapidly) that there are some major physical differences that are issues. I know that from ~2002 they went to cable shifters as one issue but for the life of me I cannot remember where the response is or the details. Do you have any input.
Here' a 1999 996Cup trans that I looked at as one of the closest to being useable in a 993
