Japan emmission laws aren't as strict as they are in other parts of the world. Thus why the US only ever got the 2.5LT in the WRX & Liberty/Legacy.
I think Japan is only now just starting to use the 2.5LT in the Legacy - Started with the S402?
That's actually why Nissan had to discontinue the SR20DET & the RB26DETT... Their new cars would be very popular in please like the US, but those engines are now considered to be "dirty"... Same as Mitsubishi discontinuing their 4G63 EVO motor.
