Nz market have oil burn issues, (same motor as the USA, and a class action has been upheld against soa because of it)
Jdm 2Lt have issues with piston rings, they arent up to the task. Resulting blowby carbons up the bigend bearing seats and they spin. Blowby carbon build up to the point of a 500km oil change looking like the 10,000km changes I did in my old skyline with borked rings.
When my grb was rebuilt, Subaru Japan, as well as cometic and a few other major manufacturers had run out of head gaskets. World wide. Subtech had done 10 grb rebuilds in the month previous to mine letting go, and are still pretty flat out. They generally let go between 120-150k, even with an immaculate service history
