What group size? Amazon carries them.
You might also consider this, or possibly two in parallel.
Alien Motion 12v 22 Cell LiFePO4 Heavy Duty Lithium Ion Battery (Right Positive) : Amazon.com : Automotive
It is a LiFePo4 12V, 22 cell battery, with up to 400 Amps draw. I know it says it is for 2000cc, but I expect it will work in the 911. Weighs 3 lbs 5oz and no acid. You can mount them in any position. Two of them would definitely fire off the 911! Weight would be 6 lbs 10 oz.
