Progress is being made. Both engines have been removed. However, to my dismay I discovered the block castings for FWD and AWD cars are different on the 1ZZ engines.
AWD cars have 2 extra threaded studs just above the freeze plug at the back of the engine to accept a cast iron mount bracket that connects to the AWD differential (pictures forthcoming). Also there are threaded holes just below the power steering pump that accept bolts that hold another bracket that connects the right side of the ADW differential to the block. I should be able to drill and tap these holes into the FWD engine.
I am too far into this to give up now. Plus I believe there is a solution. I have a few ideas. One is to have a bracket made from 1/4 inch stock that bolts to the diff on one end and will angle over toward the bell housing where two of the bolts that merry the block and transmission will be used to secure the bracket. I had another suggestion to get threaded studs welded to the block, but I don't know enough about that and whether the composition of the block will allow for any kind of welding.
Suggestions welcome. I can't afford another engine (even if I could find one) or a rebuild of the current AWD engine.
