Looking at a few JDM options that will become import legal in the next few years, the 1JZ keeps popping up.
Has anyone explored the upper limits of the motor? Is it as bulletproof as the 2JZ?

I mean, the 2JZ is a stroked 1JZ ...
They are stout engines.
I'm not an expert by any means, but the JZ seems to be able to take quite a bit of abuse with some or most of its stock internals.
It has to be popular for a reason, right?
For what it's worth, when I was still living in Wisconsin and researching various JDM build/swap options, I got the impression that the Toyota JZ-series engines are much more robust out of the box for track work than the comparable Nissan RB-series engines, which have various oiling system issues that need to be addressed before you really run them hard. The 1JZ seems to be pretty bulletproof and beloved in certain corners of the globe but we never officially got it here so it's overshadowed by the 2JZ.
I shared a shop space with a dude who had a 1JZ Cressida drift car; he beat the absolute snot out of that thing and it never skipped a beat, though I couldn't say what all he had done to it.
From some light research, 400whp seems to be easy/common, 500whp is achievable with a bunch of supporting mods, handful of people out there claiming 600 but they're into the deep end from a time/money perspective.
Biggest weak link seems to be the transmission, seems like Supra 6 speed swaps used to be popular before they got very expensive
Unfortunately I showed Mrs. Calteg a beautiful Toyota Blit wagon yesterday, she was....unimpressed
I am not sure what your goals are, but if you are trying to find an engine to swap into a car, a 7MGTE will do 400whp easily and 500 is not that far off. A 5 speed R154 from an MK3 Supra is the way to go, stronger than the MK4 6 speed.
If looking at a jap spec car like an MK3 Supra/Soarer with the 1JZ, then disregard :D
Specifically looking at a Mark II Blit, though they won't be import legal for another 4 years.
The intersection of "fast wagon" "not German" and "relatively inexpensive" is pretty thin.
For now I'm happy with my V60, but at some point I'd like to own/build a ridiculously fast wagon.

I suspect that is because RBs make power with revs while JZs make power with boost.
Anything with a crank snout oil pump and a long crankshaft will have oil pump problems. Heck, Audi inline fives eat oil pumps at only 8000rpm.
They also have weird windage issues, which I understand is also an RB thing... something in the Nissan's case about the twin cam box setup making the breather system a little cramped. Audi crankcase breather setup is just chunderheaded and beyond the scope of this thread for a long winded rant about such a poor design from a country that had good aerodynamicists.
When pondering one swapped into an rx8 the issuw with power seemed to be the ceramic turbo blades on the factory setup. They seem to be solid citizens if not as rowdy as their big brother.
