Decoding Engine Codes

[4agzeSE]

How to Decode the Model number of your Toyota


Model code consists of 2 letters followed by 2 or later 3 numbers.
Example: MK1 MR2 model code is AW-11. The first letter means that this model has a A-series engine, in this case a 4A-GZE
the second letter relates to the chassis family, in this case a W which is a MR2

S Crown
X Cressida, Mark II, Chaser, Cresta
A RWD Carina Celica, Celica Supra, Supra
V Camry, Vista
T Corona, FWD/4WD Celica, FWD Carina
W MR2
E Corolla
P Starlet
L Tercel

Maybe someone can tell us what the last two digits mean?

Decoding Engine Codes

The letters before the hypen:
The letters indicate the engine family, for example in 18R-G the engine family is R, in 2JZ-GTE the family
is JZ. The number(s) at the beginning is the number of the are for a certain bottom end version (block,
bore, stroke). The larger the number, the newer the bottom end version. It may seem like the larger the
number, the larger the displacement but this is not always true.

The letters after the hypen:
G = twin cam (wide angle, 45 degrees or more between the intake and exhaust valves)
F = "economical" twin cam (narrow angle, around 22 degrees)
T = turbocharged
Z = supercharged
E = fuel injection
i = single point fuel injection
L = lean combustion
B = twin carbs
R = air injection
U = emission package (Japan)
C = emission package (California)
LPG = LPG fuel
