From what i know, it has the same head, block and just different in pistons (uses the same rod as well). The reason for the ka20de is for fuel economy without sacrificing the drivability in a 4 wheel drive as the hp is rated at 145 tq 140 vrs the sr20de motor which is alot less. This information i got from a friend who lives in Japan. He said insurance is a little less in this engine then the year older one with the ka24de. He was not sure if it is the reason or just to added safety features.

The important information I don’t have yet about this Nissan KA Engine is, what years and trim levels had that KA20DE. As the Nissan KA42E and KA24DE are real motors that come in the 240sx. KA20DE does not exist in some cars models or is in some irrelavent truck that nobody cares about. The best Nissan ka Engine are still the early model os SR20DET that came in Japanese silvias and 180sx’s.
