Have you seen those Toyota engine codes or been asked what code a motor was? Have you ever wondered exactly what the jumble of letters and numbers meant?
First of all, one needs to realize that Toyota, like GM, Ford, etc., has engine "families". However, rather than calling them names such as "big block" or "small block," Toyota assigns them a letter code. The engine family code is the first letter (not the first numeral). The codes are as follows:
A-series: 1.5L, 1.6L and 1.8L, belt-driven overhead cam motors used in Corollas, later Celicas, early Tercels, Chevy Novas (NUMMI-built), and Geo Prizms;
E-series: 1.4L and 1.5L overhead cam, belt-driven engines used in ’88 and up Tercels and Paseos;
F-series: 3.9L, 4.0L, 4.2L, pushrod straight six engines used in Landcruisers;
R-series: 1.8L/2.4L, overhead cam, chain-driven engines used in rear wheel drive only Coronas, older Celicas and pickups;
M-series: 2.2L through 3.0L overhead cam straight six engines used in Cressidas and Supras;
S-series: 2.0L and 2.2L belt-driven OHC engines used in Camrys, Celicas and MR2s;
VZ-series: 2.5L, 3.0L and 3.4L V6 engines used in Camrys, pickups, Lexus ES and T100s;
UZ-series: 4.0L V8 engines used in the Lexus LS400 and SC400.
Toyota manufactures motors from the very small up to large industrial diesels, so this is only a partial listing of the more common engine families. However, hopefully this information will bring some sense of order to the confusing alphabet soup of Toyota engine classifications.
maybe of some help
thnx
