Damn. This thread is almost three years old. Holy cow.

Yeah, if it were just that simple.
What you will need to do the swap.
RB26DETT engine, ECU and wiring harness, minus trans.RB25DET 5 speed transModified RB25DET oil pan (because the front diff of the GT-R goes through the oil pan on the RB26.)The biggest issue is the money you're going to spend getting an RB26 engine and an RB25 trans.
People have cut out the diff on the oil pan and modified it somewhat (there is a thread on it somewhere here in the Skyline forum) and have also cut off the transfer case from the RB26 trans and just welded a plate over the hole. Don't know if I'd go that route, though.
All the info you need is on NICO, just need to do a good search for it and you can find it.
