To run your vehicle in 2WD mode, the transfer case will have to be bled and ATTESSA system disconnected electronically. For the R32 GTR, all we need to do is to remove the fuse, which electonically disables the system. Thus to be able to switch between 4WD and 2WD in your Stagea, we will need to modifiy your car by removing the line pressure valve in the 4WD system. The downside of this will be that the ATTESSA system will not react as fast as it should do, due to not having a constant line pressure going to the transfer case, and will react like the slower R32 GTR ATTESSA system.
