Toyota Engine Codes
Toyota Engine Codes
The first numeric characters specify the engine block's generation
The next one or two letters specify the engine family
The suffix (separated by a dash) specifies the features of the engine:
A Valvematic variable lift intake head
B Twin SU-style side-draft carburetors
After 2000 indicates E85 Ethanol fuel.[citation needed]
C Carburated / California Emissions Controlled
D Twin Downdraft carburetors
E Electronic Fuel injection
F Economy narrow-angle valve DOHC
G Performance wide-angle valve DOHC
H High compression like 9.8:1 (example: 5E-FHE)
High pressure charged (example: 2L-THE)
I Single-point fuel injection
J Autochoke (Early models) or unknown pollution control
L Transverse
M Philippines' market (meaning unknown)
N CNG fuel
P LPG fuel
R Low Compression (For 87 and below octane fuel)
S Swirl intake (1980s)
SE Direct injection (1990s)
T Turbocharged
U With Catalytic converter Japan-spec emissions
V Common Rail Diesel Injection (D-4D)
X Atkinson cycle (typically also indicates a Hybrid engine, as Toyota only uses the Atkinson cycle with hybrids)
Z Supercharged
so a 1G-FE would represent first generation, with the family G, then it is narrow angled valves and electronically injected.
For asi it qould be 1st generation, UZ family, narrow angled valves and electronically injected fuel. (1uzfe)
For stav it would be 1st generation, G family wide angle valves, turbocharged and then electrionically fuel injected.
Hope this helps anyone
