Does anybody recognize this animal?

What does it fit??

 

 

 

 

 

 

[Jesse C.]

That looks like something straight off a JDM only type engine!

 

I would call that "Dead Weight"!

Dead weight?

Cool , I'll put it in my aluminum boat. What anchor?

[datzenmike]

Electric choke, accelerator pump. Has the swirl inducing butterflies like the KA24E and DE.

 

I would say a carb manifold for a KA24DE. Even has the DE manifold bolt pattern . Or close to it.

 

Where in the world would they have a non EFI KA24DE????

[datsunaholic]

There's no such thing as a (factory) carbbed KA24DE (being the "E" stands for EFI). There IS such thing as a KA20... South Africa...?

[ggzilla]

KA24S, single-carb engine was fitted to the 1990-1993 Nissan 720 pickup.

[datzenmike]

What I'm trying to say Doug is it's from a dual cam head.

 

Then it's a KA24DS as I think it's from a DOHC.

 

 

 

The intake on the left is from the KA24DE and is I think, a match.

hmmm.. im not seein the bolt patterns bein the same mike.. could it be from a napz? or some sort of diesel?

[datzenmike]

:o while not exact, it is too close to deny it's not related. Maybe the head is drilled different but I think it fits the 4 valve KA motor.

[lynchfourtwenty]

ya it says nissan on the carb also haha

[ggzilla]

carbureted KA24?

[datsunaholic]

No, I meant KA20, as in a 2.0L KA. South Aftrica had KA20DE, but it's possible there's a non-EFI version. Dual or single I can't say. I know Africa had carbbed VG30s.

 

What it is NOT is a NAPS-Z intake. They look nothing like that-

 

(Z24 ones will be square but have the same pattern)

 

Nor is it a diesel as you don't have carbs on diesels and diesels can't use standard PCV valves.

 

It's probably something completely different. Definately post-1980, and it's a feedback carb judging by the wires so probably post 1984.

 

What I don't have is a good sense of scale. That carb looks really small- like something sub-2L, perhaps a GA16 or E16S. Or a Nissan Micra (MA12A). But the MA12 doesn't have that coolant passage on the side of the end runner.

[lynchfourtwenty]

thats a good point, the b11/b12 sentras were carb'd (i dont know much about the naps or diesel lol)

[nismo dr]

I think it is off a ga16

[nismo dr]

 

carb looks same - not sure exactly what that is

 

 

Induction Kit to fit Nissan Sentra / Sabre 160, vertical throttle body model

[jefe de jefes]

there are numbers stamped on the carb but they are small and faded.

[datzenmike]

carbureted KA24?

 

I think that's the throttle body D21 Hardbody truck KA24E

that doesnt explane the coolent passage in the mani

[elmerfudpucker]

Hopefully I dont sound like too much of an idiot, but what is with the valves in the intake if it already has a carb???:confused:

The butterfly valves are operated by manifold vacuum and are closed at idle and light throttle. The dual valves and huge ports cause the air/fuel to slow down too much on light throttle, so their purpose is to speed the air up around the injector and create turbulence to better mix the fuel and air before it enters the cylinder. As throttle increases, vacuum drops and the butterfly valves open.

 

Only an idiot wouldn't ask a question.
