Recently read in an ad of, apparently, a new turbo installed in the diesel engine of the Toyota Fortuner.
I think they call it VARIABLE Nozzle Turbo - sounds so much like the VARIABLE-GEOMETRY TURBO (V-GT) installed in the new Monteros.
Reading thru the specs, though, the Fortuner 3.0L diesel variant "only" churns out 163/3400 ps/rpm of horses & 343Nm/1400-3200rpm of pull & compared against the Montero 2.5L V-GT diesel engine. it pales, relatively, in output on both counts (175/4000 ps/rpm & torque of 350Nm/1800-3500rpm).
Is this really a new turbo tech similar to V-GT? If yes, how come it generates lesser output even with a higher engine displacement?
(I am not familiar with the numbers of the previous 3.0L turbo-diesel engine of the Fortuner.)
