Reading your turbo
The turbo model says a great deal about the features of your turbocharger.
For example, in the T Series, turbo model TO4B59 is formed
as follows: TO4 = frame size (74.2mm turbine); B = the design; and 59 = the 59th
TO4B that we made, usually specific to one customer.
For the GT Series, model GT4082SN translates as follows:
GT40 = (77mm turbine); 82 = 82mm compressor wheel; S = single passage bypass
turbine; and N = ported shroud.
