Hi, My brother in Law has recently aquired a P Reg RR P38 with electronic gearbox. The motor is shot, and he has a mazda 2.9 motor to put in it (currently in a RR classic).
my question is, what does he need to buy and from whom, to make the electronic gearbox work with the Mazda engine?
Or could he move the RR Classic GB along with the Mazda during the transplant?
cheers
