It's also just hard to believe that Nissan wouldn't do anything to the motor over the years, though production for standard SR20VE's was not very long. But as we see in changes between High ports, then to low ports, etc. Nissan just loves to continue improving on the motor designs after they are released.
This is why I think there are so many rumors about different SR20VE's.
