there's an awesome source right there
i haven't had personal experience in swapping in a 1j just yet... i work on genuine jza70's heh
there is a company that is making solid engine mounts for the 1jz.. i believe to even possibly fit into the pre 89 crossmember so you don't need to swap that in
but if ya can't find the mounts....
crossmember
engine
7mgte 5sp box
1jz bellhousing
if non turbo it is suggested to swap in a 3.9 diff rather than keep your 4.5 or 4.3 whichever ones you have there
power steering, you will need to swap some in.. i believe most are using 2jz power steering lines? (Alby what did you use)
ecu
engine harness (make sure you get the engine harness and ecu from the same 1jz vehicle... soarers and supras use different harnesses and ecus)
if you find a soarer 1jz, find yourself some jza70 engine mount brackets (ones that bolt on the block) as soarers sit higher and further forward than jza70's
and some wiring diagrams which
www.1jz-gte.us should have
good soldering ability and electrical knowledge
and good luck with the swap
