when i test fitted my 2jz it was right at the steering rack.
once i remove the stock tranny mount brackets i would be able to move it back about 1 to 1.5 inches.
and i think that the shifter location would be perfect.
any further back and the shifter would be too far back.
here is a pic of the mock up with the front sump pan
here is one with the rear sump.
