The Japanese are taxed on liter displacement in their cars, so a 3 liter is alot more expensive to own than a 2 liter. For this reason you see many cars with a 2 liter 6. Dimensionally the VG20 is a smaller more compact block than the larger VG sisters as well. To change stroke you lengthen or shorten the rods and you can also change the piston pin to skirt height so that the pin is closer or farther away from the oil control ring. The piston weight doesn't change much if at all only the pin placement.
Also remember the ZR1 is powered by an RB20...
