Toyota engine codes are split into two sections:
1. Before the dash - Which represents the family or series of the engine (i.e. 7M-GTE.)
2. After the dash - Which represents the engine features (i.e. 7M-GTE.)
#1 - Before the Dash:
The numbers represents a revision of the bottem end for example bore, stroke, and block.
A = A series engine, 4 cyl gasoline. Family of inline-4 configuration engiens with a displacement ranging from 1.3L to 1.8L. Series began in the late 1970s with the 1A, a SOHC with a displacement of 1.5L. In 1998, the 7A-FE was the last A engine in the family, a 1.8L DOHC engine that produced 115 HP.
AZ = AZ series engine, 4 cyl, gasoline. Family of straight-4 piston engines. Uses an aluminum engine block & aluminum DOHC cylinder heads. Has MFI FI and 4 valves per cylinder with VVT-i and features forged steel connecting rods.
C = C series engine, 4 cyl diesel.
G = G series engine, 6 cyl gasoline, family of straight-6 piston engines produced from 1979 through 1998. Only a single displacement, 2.0L was produced in this series. All were belt-driven OHC engines, with multivalve DOHC and even variable valve timing added later. These were used as a lower-displacement alternative to the more-common M family straight-6.
JZ = JZ series engine, 6 cyl gasoline, family of straight-6 engines.
K = K series engine, 4 cyl gasoline, pushrod. Family of straight-4 engine produced from 1966 through 1998. 2-valve pushrod design, a rarity for the company.
M = M series engine, 6 cyl gasoline, family of straight-6 engines used from the 1960s through the 1990s. All M-family engines were OHC designs with a chain-driven camshaft giving way to a belt after 1980. The 4M-E was notable in that it was the first Toyota engine to be equipped with fuel injection. The M family was commonly found on the large Toyota Crown, Celica Supra, and Supra.
MZ = MZ series engine, V6 piston driven, aluminum engine block and aluminum DOHC cylinder heads. The cylinders are lined with cast iron. It uses MFI fuel injection, has 4 valves per cylinder and features a one-piece cast camshaft and cast aluminum intake manifold.
NZ = NZ series engine, 4 cyl gasoline, family of straight-4 piston engines. The 1NZ uses aluminum blocks and DOHC cylinder heads. It also uses SFI FI, and has 4 valves per cylinder with VVT-i.
P = P series engine, 4 cyl gasoline, family of straight-4 engine produced from 1959 through 1979.
R = R series engine, 4 cyl gasoline. Family of straight-4 engines produced from 1953 through 1990. Designed for longitudinal use in such vehicles as the Celica and Cressida. OHC versions featured a chain-driven camshaft.
RZ = RZ series engine, 4 cyl gasoline, family of straight-4 engines usign a cast iron engine block & aluminum DOHC cylinder heads. Has MFI FI, 4 valves per cylinder and features forged steel connecting rods.
S = S series engine, 4 cyl gasoline.
T = T series engine, 4 cyl, gasoline, family of straight-4 engines. Began as an OHV design, but a chain-driven DOHC variant came later.
U = U series engine, series of flat-twin engines produced in the 1960s and 1970s.
UZ = UZ series engine, 8 cyl gasoline, V8.
VZ = VZ series engine, 6 cyl gasoline, V6.
ZZ = ZZ series engine, 4 cyl gasoline, family of straight-4 piston engines. The series uses an aluminum engine block and aluminum DOHC 4-valve cylinder heads.
Here is a different, more simpler, summation:
(All engines cast iron block, alloy head unless otherwise mentioned.)
A series (inline 4, belt, 1.3-1.6L, 1978-): Corolla FWD/RWD, MR2, Tercel FWD

E series (inline 4, belt, 1.0-1.5L, 1985-): Corolla FWD, Tercel FWD, Paseo
F series (inline 6, 3.9-4.3L, cast iron head, 1948-1992)
FZ series (6 cylinders, 4.5L, 1993-)

GZ series (V12, 5.0l, 1997-)
JZ series (inline 6, belt, 3.0L, 1993-)
K series (inline 4, chain, 1.0-1.5L, 1966-1989+): Corolla RWD, Starlet RWD, Lite-ace
