The G50/52 is hard to come by. Cody Loveland Racing has a recently rebuilt one for sale. $16k+freight.

I must say, the range of transaxles that fit an Ultima is vast.

I wish there was a site that can list them all with things like: how much HP will it handle? and Does this have to be inverted or not in an Ultima

Hard to pick the right one on a budget.

All Porsche g boxes need to be inverted, I believe Auto Bionics in the UK has mated a Porsche Automatic to an LS motor.
Depending on how deep your wallet goes, there are options.
Porsche boxes are readily available with some caveats G50-50 out of the 89 911 turbo bring top dollar. They are the strongest of the g-boxes.

As for horse power capabilities, you will break the tires loose before anything else, unless you like dumping the clutch at 7 grand.

I have personally run a G50-50 behind an LS7 putting almost 700 to the rear wheels.

PS. I may have a complete package G50-50 available soon.
