Making a vr2

Hello Guys, I need some tips and info about engine swapping 4g63 stock engine with a 6a13tt into i.

The questions are:
1. Will the 6a13tt engine fit on the engine bay?
2. Are the mounting points the same with a vr4 or do I have to make custom ones.
3.Do I need to swap the transfer case also since it will run on 4wd? (there is a possible conversion to AWD once the swap is successful)
4. Do I need to remap the ECU or should I just swap with a vr4 ECU?

Any tips is very much appreciated.

1. The 6A13TT will fit in the bay no problem.
2. The 6A13TT mounts will fit, you might need the front subframe? I'm sure you won't need any custome parts, nust buy a rusty VR4 for cheap as a donor.
3. AWD conversion is difficult as the floor of the car is different between FWD chassis and 4WD chassis.
4. You would need a 6A13TT ecu.
