I second "alaxfire" comments about a temp hoist (albeit cautiously).
I had a similar need on my old saab. I had to remove the trans (which is underneath the engine and is also the oil pan, and thus what supports the engine) and support the engine in very tight quarters while the trans was refurbished. A cherry picker would have blocked the garage door from closing, which is frowned upon in an apt complex

This poor mans engine support also provided me with much needed access underneath the car whereas a cherry picker takes up a good deal of realestate.
One side of the support rests on the drivers side crossmember whilst the other hits the floor with a cross piece.

Another bit of fun was reversing the gears in a ratchet strap to lower the trans from above...and then hoist the new bit back in place.
