It should be a straight forward swap but there are still a few things to worry about:
1. I don't now if the 22R version of the Cressida uses the same crossmember as the 7M version.
If they use the same crossmember then the swap will be almost trivial.
If they use different crossmembers then life will be hard.
Since most of us comes from countries that only have the 7M version (US, UK, Australia), a photo of the 22R version crossmember will help us judge that.
Different engines have the sump in different places and the crossmember has to bend differently to match.
The usual choices are front sump, mid sump, rear sump.
As mentioned above the W55/56/57/58/59 are interchangeable with each other.
However, the bolt pattern between the bell-housing and the engine is different for the 22R and the 7M.
If you can find a manual 7M bell-housing then it will fit in no problem.
If you can't find a manual 7M bell-housing then it won't work.
The auto that comes with the 7M will slot in nicely (there are multiple holes in the chassis for the bolts for different transmissions).
I can't remember if the auto selector comes up in the same place for the Cressida and Supra - anybody else know?
The tail shaft will probably be a different length - a local speed shop can tell you who can shorten/lengthen that for you.
The auto should have the neutral switch wired up (not strictly necessary but much safer).
3. Power steering pump, air conditioner, radiator hoses, air intake hoses, electrical lines
May require some thought to reroute them.
Not insurmountable but sometimes requires a lot of frowning before the answer appears.
Make have to buy some new parts like the radiator hoses.
4. The engine computer will be different.
You will need to find wiring diagrams for the 22R Cressida, the 7M Cressida and the 7M Supra.
These aren't too hard to find on Ebay or the internet but forums rules prevent us from doing this for you.
You will need to have an exhaust shop adapt the 7M exhaust manifold to the existing pipe.
Not super difficult with the correct tools (welder, pipe bender) but not possible with just hand tools.
Or get one from a wreck.
6. Double check how many fuel lines go from fuel tank to engine and back.
1 from tank to engine, sometimes a return line and a line from the charcoal canister to the tank.
Might need to add or blank off the return line.
Not too hard.
7. If you are from a hot country then think about using a thermo fan instead of the normal engine fan.
