I dont even think Nissan have that information as they use different turbos on
the same model car.Trying to get the information from turbo workshops is pretty
hard as they are pretty tight liped about handing out specs.Something with an
A/R of 0.89 would probably be from a larger diesel engine like a patrol.I might
try to get an idendification tag book from Garrett.
