I'm in Australia, and am curious in regard to HP output of the 3uzfe, as it changes from 285 to 300hp, I'm guessing all the 3rd Generation Gs430s vehicles were tuned to 300hp?
Thank you

 

Not sure about Australia, because I wasn’t aware of the GS430 being available there? But in the USA market the GS430 was always rated at 300 hp, same as the GS400, the 3UZ in the LS430 was rated at 290hp, and I am not sure, but I believe the SC430 was rated at the same 290, I believe the engine was identical but the LS/SC had a more restrictive exhaust but that could easily have just been a marketing gimmick.
I thought the Australian Market was the same as the Japanese Market and offered the 3.5 in petrol or hybrid but never offered the V8 in the GS in the home market?
