all i can find on it.
Let's work through one... GGKBRTAR33VDAA---B
The first digit defines the body type... In this case G for 2 door Coupe... (It's B for 4 door Sedan)
The next 2 digits define the engine type and size (note: not the fact that it is NA or Turbo)... in this case GK for RB25DE(T)
The next digit (4) defines the drive type... In this case B for 2WD...
The next digit (5) is R across all R33's... I'm unsure of its significance... Some translation is required here...
The next digit (6) defines the model spec... (eg: GTS, GTS25, GTS4, GTS25T/M, GTS25/S, GTR, etc...) In this case it is T for GTS25T/M + GTS25/S (note: we still don't know if it is NA or turbo yet)
The next digit (7) defines the transmission... In this case A for 4 speed auto... (It's F for 5 speed manual)
The next 3 digits (8, 9 & 10) define the Model Series... In this case R33 for (duh) R33...
Now comes the tricky part...
The next digit (11) defines the induction system... In this case it's V for Forced Induction... (It's E for EGI / NA)... Some further translation is required here...
The next digit (12) can be either D or Z... I'm unsure of its significance... Some translation is required here...
The next digit (13) is A across all R33's... I'm unsure of its significance... Some translation is required here...
Shown below are all possible entries for the first 13 digits of the R33 Model Codes...
Note that different years have different designations for the digit (mainly to cater for the GTR's and GTS4's)...
R33 Model Codes (14-18)
Erghh... So many options...
The only one I have semi worked out is the last digit (18) which will be A if you have an Active LSD, B if you have ABS, and C if you have an Active LSD and ABS... There are heaps more options for digit 18 though...
It appears digit 14 is mainly focused on the wheel and tyre sizes...
It appears digit 15 is mainly focused on the electronic options (eg, ASCD (cruise), GT spoiler, etc)
I am unsure what digit 16 is mainly focused on...
It appears digit 17 is mainly focused on the AV options (eg, CD, MD, Stacker, etc...)
