a guy recently came onto the forums, he has a 2wd hilux with a 1G-GTZE in it
im pretty sure if u search the forums you will find who he is, he may be able to help.
also this topic has raised a lot of interest on the performance forums, there is a VERY big thread with many inciteful posts, diagrams and info, well worth a look.
good luck with the project..
EDIT: by the way if you do start this project u have to start with a complete 1G-GZE and add bits from the GTE, not the other way round.
