Hmm I see some misinformation here. No eclipse ever came with a wideblock. Trucks did get both, so the 4g63 you want is in 87up 2.0 g63b trucks with an automatic transmission. See here for more detail:

No there is no off the shelf way to use your stock 3.0 trans with any 4G6X series of motor. What you can do is source the g63b wideblock from a truck, drop all the motor bits with the exception of the crank (keep the truck crank it is known to be forged) into the truck block, and use the 4Cyl montero trans.

Any other questions feel free to ask. I've done the 4G64 wideblock swap into my quest, and am really considering it for my Montero.
