there are very few people who start this process who REALLY follow through with it and see it to the end.
There's a guy on SF in the MKIII section who built an insane 1.5JZ for his MKIII supra. He had a huge build up thread for it. (but since the search function is gone there you'll have a hell of a time finding it)
the advantage is having the displacement of a 2J motor with the head flow of a 1J motor. The only time I think this is a good idea is if you either: 1. somehow destroy your 2j head and get a 1j head or 2. somehow blow your 1j block and get a 2j block

Ultimately, the 1.5JZ motor is a clever way to gain displacement when you blow the bottom end of your 1JZ. I don't know if anyone voluntarily puts the 1.5JZ together from the go.
If you want the big power (500+ whp), go 2JZ. If you want a JDM-only engine that can take a beating, go with the 1JZ.
Honestly, BoostedNY, stop wasting the time of the people on this forum and:
(1) Search more on this forum and Supraforums
(2) Make a firm, realictic goal and take strides toward that
Your one-a-month posts dealing with open-ended, general questions about performance engines is getting old. Make a goal (400whp, 12s 1/4-mile, beat my friends Talon TSi), and then your research can be more guided.

I looked into this a long time ago, they said with the stock ceramic 1JZ twins, a 3L block will have you at full spool by 1800 RPM.
And also that the ceramic turbos will last about 1500 miles doing that.

There is nothing "considered" a 1.5jz. The 1.5JZ is what people refer to after mating the head of a 1J to the block of the 2J. It is not MAINLY used in Japan....there are quite a few examples of them here is the US and around the world.
Again, it is not a factory motor. It is not an actual motor designation. In essence, it is a slang term to describe the "melding" of two different engines.
