Again not much has changed except the Engine capacity and related measurements.

 

I THINK this is a 4K

mate your motor should be a k4-c. it should be imprinted into the block on the drivers sie of the motor, and looking at some of the specs of the engine, i would say it is a k4c. they're are a good engine. mines done 142,000 km, first time around and no rebuilds.

4K-C dude

the C stands for Carby......

 

hmmm......i wonder weather that would make mine a

 

5K - W.......hehehehe..... W = Weber...

Actually I thought the C was just a designaton given for emissions friendly engines, possibly C for California, the first place they really started cracking down on this sort of thing? 3K-B was the high compression twin carb motor, and there was a 3K-d as well...... *shrugs*

 

Thoughts?

Yes, "C" was for "California", and has to do with the emissions.

meh.....i still reckon its easier to remember that c = carby....

 

 

hehehe....even though its wrong.....its still right in a way....buggered if i'll be saying that my engine is related to america.

 

just for confirmation..

 

Engine Codes

 

C = emission package (California)

45kw at the flywheel. I've still got the original showroom booklet from back in 1980. I'll crack it out one day and post some more specs.

I'm not so sure the "-C" in 4K-C means california emissions.

 

the americans had air injection pumps on their engines. these pump air into the exhaust ports of their engines, to dilute the exhaust gas emissions. we didn't get them on our 4K-C's. their 4K-C is different to our 4K-C.

U is japanese emissions...

 

R = air injection

 

So the Cali 4K-C should really be a 4K-RC

not as restrictive i think nicko

 

not that i know or anything, just a guess :jason:

 

cause yeh, the engine in my panelvan is actually labelled as a 4K-U

Edited November 3, 200421 yr by NiteP]-[yRe

Doesnt the 4K-U have dished pistons?

yup

 

would be a good engine to decompress for forced induction, using an earlier head.
