Holy shit thats some damage to the block!

Jamsport or pumaspeed may be able to give you pointers as I know they have done the 2.3 conversion a fair few times.

The only thing I know for sure is you need a shim under the engine mount to lift the engine a wee bit. And I'm pretty positive the ecu and gearbox can be used.

Keep us posted on your progress would be interesting to see what needs to be done to get her running! Good luck
