Hello fellow corolla fans,

I own a 1974 KE25 Coupe, Which had a Low k Japanese motor put in it a few years before i bought it, i know that it is a 4K but don't know how to tell if it is a 4KC or not? Would any one b able to tell me how 2 tell which is which and if there are any differences!

Thanks for the help as i'm fairly new to toyotas, As I was a Die hard Holden fan until I finished fixing up my KE25 Coupe! and now i love corollas!!

As far as I know, they are exactly the same thing, -C just means it has a carby, whereas -E would mean its fuel injected. Anyone feel free to correct me if i'm wrong though..

nah mate. that's correct!

 

c is for carby.

You made the correct choice, you will not be dissopointed :D

 

Welcome :P!

Actually I think you might be wrong... Check out the table on this page:

Superjamie is a legend I doubt he is wrong. Yes 4K-E is fuel injection but I believe 4K-C is californian emissions control... I don't know how to tell 4K-C from 4K though if anyone knows I would love to know how exactly they make it have emissions control.... that way maybe I could undo it on my engine because it probably saps power whatever it is. :D

C is for californian emissions. U is jap emissions.

Well 4K must mean minus the emission gear?

me got brain freeze.

 

:D

I thought we'd been through this before???? déjà vu

I was walking around in the storm last night with my girlfriend just for kicks and i ended up getting an icecream headache. :blink: :blink: :blink:

 

Yeah I'd assume 4K is minus the emission gear too, but what is the emission gear!? I can't seem to find anywhere that says..

i dunno about overseas. but 4k-c the c means carby 4k-e the e means electronic injection.

i dunno about overseas. but 4k-c the c means carby 4k-e the e means electronic injection.

no no no...incorrect

 

my 3K had a carby...but it was a 3K...not a 3K-C. My TA22 celica has a 2T....it has a carby....but its a 2T not a 2T-C.

 

Like I said earlier C = californian emissions.

I'm with him.. ^^^^^^^

as far as i know and i may be wrong, there is no such thing as "just a 4K". -C means californian emissions, aka that huge mass of spaghetti shit most of your engine bays started out with

 

you may have a flattop 4K-C, or a dished piston 4K-U or 4K-E bottom end with australian 4K-C carburettor on it. (you may also have some other carb, it just depends what someone had laying around at the time. my 4k-c runs a 3k-b head and 3k-h carb, which actually makes a decent attempt at an emissions system)

 

unfortunately, the only way to tell the engines is to look at the pistons. wind #1 to tdc and feel around the spark plug hole with a wooden skewer. there are two different types of dish, doug knows more about this than i do

 

this does happen people. i know an engine builder in town who brought in about 12 4K-E motors in the 1990s to sell to people who killed their corollas. he threw away "all that fuel injection rubbish". lucky even scrounged the scrap metal yards for the efi systems, but i think we were years too late

 

3Ks are different, as some of them didn't have to conform to emissions standards as they are pre-ADR (and pre-emissions elsewhere). there is K, K-B, K-C, 3K, 3K-C, 3K-H, probably a few different 2Ks as well. i have them in a yellow book somewhere. don't worry about them for the purposes of this exercise

jamie, surely you should know that your head isn't a 3k-b head. it is simply an early 3k head off of either a single carb ke11 or a ke20.

 

all the early 3k heads ke11/ke20 ones had bigports. proper 3k-b heads have water galleries for the twincarb manifolds, and are different from your head.
