Yes it can be swapped...Yes you need the tranny from that motor..It is not worth it though..There is very little mods and parts for the 1jz..Your best bet is to just stick with a 7m..They are alot cheaper and are almost a direct swap..You can even use your stock tranny,motor mounts,radiator,etc..The main things for a 7m swap is the harness,oilpan and pickup and the intercooler ducting..Which you can use the MKIII stuf you just have to cut the holes to run it..Yes you can get more power out of a 1jz its just almost imposible to find the parts..If you went with the 2jz it would cost you 4 times as much and there would be an ass load of custom fabbing..If you want more help and knowledge on the subject then go to www.celicasupra.com/vbforums/ and just use the search at the top of the forum..
