Where are you guys getting the idea that the LSx motors weigh less than the KA? It has 2x the pistons/cylinders, one more head, and is 2.375-2.911 times bigger in displacement. It may be all aluminum, but aluminum isn't half the weight of iron, last I checked. And I've yet to see any valid evidence of such.
I'm not saying the whole LSx swap (T-56, mounts, driveshaft, etc) can't turn out to be lighter than the KA setup, but I'd like to see concrete evidence that the LSx engine itself is lighter than the KA. And yes, before anyone gets ill, I know of ALL the advantages of the LSx motors in our cars. I plan to do this or a VQ35 eventually anyway.

For now, take a peak:
Engine Swap Forum - Official Engine and Tranny Weight List <---lists KA (330lbs), VQ35 (329lbs), and LS1, and others.
Motor Weight Comparison
LS1/6 Engine weight: Hybrids: Nissan Forums / Infiniti Forums - NICOclub
WikiAnswers - What is the weight of a chevrolet LS1 engine
MX-5 Miata Forum - LS1 vs 5.0
