alright i guess i should have been more specific,i was woundering if it would just fit in just like my old motor and use all the same motor mounts and what not ?and how much do you think it would cost to do a swap like this right?
no. The 87-88 are the hardest to swap. That said, you need engine mounts or a new front subframe, the bellhousing to line up with the transmission, to extend the main engine wiring harness, the ECU, potentially to splice into the dash harness so the various indicators work, intercooler and plumbing, downpipe and the fromt portion of the exhaust etc. Certainly not a plug and play engine, even in the 89+ chassis. One place to check since you're out there would be driftmotion.com. They seem to do the swap quite a bit and might be local to you.
rebuild the 7m-gte, definetely worth the money its a good engine. You can make something pretty beastly out of that with the money that it would cost you to do the 1J (stock motor) swap.
highest record on the 7m-gte is 730hp and that guy had a lot of time and money sunk into it. 400 is an easy achievable goal however. Staying street legal gets tricky. You're in Cali I see (as am I). With the smog-laws in this state it gets tricky on some mods, but it isnt impossible. I believe turbo upgrades are legal, intercoolers dont matter to smog, if you get a CARB legal intake and exhaust you're in the clear hmmm... thats all I can think of haha.
I might also poke in real quick here, it's not GTTE, it's GTE. Nissan used two T's to indicate twin turbo, Toyota didn't name them any differently between the twins and the singles. The proper name is 1JZ-GTE.

Who came up with this 500px wide BS?

Do you have pics of your Supra?
to contrast, what is the average max power that a 1jz can make?
Honestly, I havent heard too much about the 1jz's getting built really. I have a video on my phone of a 1jz'd MKIII running at a strip and it ran 13's but since my friend sent me the vid from PA, I dont know any details on the car. Another guy I know had a 1jz'd MKIII about 15 minutes north of me, to my knowledge it was all stock and pretty quick. However i'm not going to say any numbers because I dont know.
I'm sure 1jz's are capable of 600 easy if a 7m isnt that difficult to take to 500.
Again, I can't claim any real numbers because I myself havent seen a modded 1jz.
there is a guy on my celica supra fourm that has a swapped 1jz running "433rwhp/378rwtq @ 14psi 12.25 @ 122.71 on street tires." He has some vids of his runs too, pretty sick, but I'm sure its capable of more. I think hes still running on stock fueling.
I wonder if their downfall is the smaller displacement of the motor? (2.5 L)

I've wondered that too. But what about the 1.5jz-gte? Doesnt the 2jz head make the 1jz a 3 liter? I read that there is no real noticeable difference on the 1jz with the 1jz head and the 2jz head performance-wise.
Change the bottom end, not the head. The 2j is in essence a stroked 1j, and that's all in the block. The reason for the 1.5J was a lot of people got the 1j and turbokits etc, then wanted more and that meant a 3l block. The heads are not the same however, and to keep the turbo kits and such to make it remotely affordable, they had to stay with the 1j head.
