the economy 4A's are not carbed, and have not been for a very long time..
(but you new that, right???)

here is the full (current) info for the 4A series...

BEFORE "-":
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.

AFTER "-":
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

an dI have the full link above ;) (sorry..)

the 4A's are really very good strong engines, well worth a lot of 'development' ;)

(maybe not quite as much as the 7M's and 1JZ/2JZ's ;)
