3k Engines - What Does It Mean??

Featured Replies

The 3K engine has a few different codes.

 

What do they mean?

 

3K

3K-D

3K-B

3K-H

3K-C

 

As Pauline Hanson said "Please Explain"

Edited by AE35

the only one i know off the top of my head is c means it conforms to the californian emmision standards which are one of the highest standards in the world

 

h i have no idea about same for the others cheers

 

other than its the 3 rd gen in the k family

does this help at all?

 

 

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.

 

After the dash.

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).

I got a 3K-H in the panel van and it hauls pretty well. Especially once i adjusted the vacuum advance on my nippon-denso distributor!

The knob on the left is to advance the timing. :jamie:

 

Who else has this style of distributor? They came out in KE20, 25 & 26 models.

Actually it's a octane selector and it's a not the best place to adjust your timing, because it allso restricts your vacuum advance actuators movement. Found in older K-engines.

 

3K-H is an older bigport engine, ours were pre -75 ones.

3K-B is obviously twin carbie
