Toyota Engine Codes

Toyota engine codes are split into two sections, the bit before the dash, and the bit after it (eg: 2JZ-GTE).

Before the dash.

The letters signify the "family" or "series" of the engine. The numbers signify a revision of the bottom end (ie: bore, stoke, block). Higher numbers don't necessarily mean a larger block.

For example, the twin turbo engines in modern Supras are the 1JZ-GTE and 2JZ-GTE. The 1JZ is a 2.5L engine, while the 2JZ is a 3.0L. Both are twin turbo inline sixes.

The letters after the dash specify the features of the engine.

G - Wide angle Twin Cam (sportier head)

F - Narrow angle Twin Cam (economical head)

T - Turbocharged

Z - Supercharged

E - Electronic Fuel Injection

U - Emissions control (Japanese)

C - Emissions control (Californian).

Great Info....

That's great info, but what is the H in 5E-FHE?

[toyotasera.co.uk]

No-one knows about the H as its rarely used.

I think of it being High compression as that is the biggest difference between the 5E-FE and 5E-FHE.
