Post EJ25 DOHC on EJ22T block

I've seen people hear people do this.
I have an '97 EJ22 n/a. This subject has been on the message board before.
I'm just wondering, how does everything work with this procedure.
How does the turbo respond to this?
Can the EJ22T crankshaft handle Dual cams? What is the final displacment?
What if one used low comp pistons?
What would the drive ratio be when connected to the stock auto transmission and what type of rear diff best works with this set up?
Of course an EJ25 intake maniforld would be needed, the next quetion, does the EJ25's ECU just plug up?
Or would there be a mountain of rewiring?

Is it worth making this engine in hopes of attaching a IHI VFxx turbo (xmember needed)or T28+?

with afc and the like, would one be able to run more than 5 PSI with stock injectors? New fuel pump would be needed and pressure controler. Would it make a difference to run dual injectors in from the Throttle body that are controlled externally?

I hope we can make sense of this!
