Well I appreciate your humble opinion and it is dualy noted for my next project, but I already ordered the GE and its on its way.

Okay, well I really want to make it to that 600 rwhp and if it is as hard as you say to do that with out a turbo ill just have to deal with it.

I was going to replace the heads and pistons, make my own intake, and get a new intake manifold, and from what i understand those are the only things that are different from the 2JZ-GTE and the 2JZ-GE.

Okay, well would the connecting rods and crank be able to handle the load?

Well either way they are both getting changed.

Well I'll just get a 2JZ-GTE head. How much are the gains from a port/polish and all that?

What is the highest comp. ratio i can go with a turbo?

Well I just want to get the project rolling before i get the turbo, so i was thinking of putting the unmoded engine in my rear-wheel-drive-converted car while im saving the money for all of the parts, so i can get one large chunk of the project out of the way and then i'd pull the engine when i got the turbo and everything and put all of the new components into the engine.

Okay, so turbo it is.
Thanks for the help, even though you haven't even touched on specifics your information is extremely helpful for planning out my project.
