From what I have researched and discovered for my '84 22R, there is no turn key for the do-it-yourselfer...
If you're in the Northwest, Toyonlyswaps will do it for you. Or you can ship it.
I'm sure it can be done for 3k, but it depends on purchase price of engine/harness/accessories, etc. plus what you may need to do to the engine(rebuild, overhaul, nothing). I purchased my 3RZ for $1500, complete. Plus the LCE performance master rebuild kit, even though my engine didn't need it at all(crosshatch hone was still visible in cylinders, 140K miles). Plus machine work, and head job. Plus Marlin clutch. Plus Chilkat mounts. Plus Walbro fuel pump. Plus plugs, wires, fuel lines, etc... I am well over 3k, and my engine is still on the stand....
