Toyota has a reputation for building bullet-proof motors with efficient designs and the engines are often over-looked in the search for big power. Some of the large capacity Toyota motors are currently making some serious horsepower, as more and ore tuners realise how well engineered these engines are.
For example, the RZ Supra's twin-turbo six can be modified to put out up to around 800 or more hp.
Toyota Engine Codes Explained
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 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 = transverse mounted engine (seems to be an obsolete code)
B = twin carbs (only used on non-twin cam engines, obsolete code)
R = air injection
S = swirl intake ports (only a few made in mid '80s)
S = direct injection & swirl pot pistons (starting from '97/98)
U = emission package (Japan)
C = emission package (California)
LPG = LPG fuelToyota Engine Specs
