way to tell which year kade?

[Blackstar]

I just recently got an engine from someone and theres some discrepency about what year it came out of. The guy said he thought it was a 93 or 94 s14. I said thats not possible, it would have to be a 95 to be an s14, then he said it it came out of the newer body style, without the flip up headlights. So my question is, is there a way by looking at the engine, (a number or something?) that can tell me if its s13 or s14?? I don't want to attempt putting it in, only to find out its not an exact fit since I have an s14. Thanks

The main difference between the s13 KA and the S14 KA is that the s13 had the coil outside of the distributor, so the s13 distributor has an extra nipple at the center for that wire. the s14 ka had this coil built into the distributor, so this Dist. has 4 plugs instead of the 5. Hope this helps.

Thanks, I'll take a look at it tomorrow morning. If it is an s13 engine, I should still be able to use it right? could I just take the distributer off of my current s14 engine? I know the intake is different also, but besides that, is there anyhthing that would require swapping or modding of parts?

[edgartheace]

The S14 enginge has the crank sensor on the rear of the block I think, instead of in the Dist. Other than that I cant think of anything else.

well it turns out it is an s13 motor. It is currently at my shop and it seems like its going to be a pain in the *** to get it to work. They're telling me I need a bunch of parts to make it work. Can anyone give me a breakdown list of what needs to be done to get an s13 ka into an s14? should I get rid of this engine and try to get an s14? I"ve been having a hard time finding one. My car already has its engine out, so if its possible I'd like to just use the engine I have. Any help would be appreciated

You can also tell the difference from the KA24de's by the SCV's there is a line connected from the back of the head with a tiny little brown connector.

What wrong with the engine that was originally in your S14? As far as what parts you need let me look at the FSM for both cars and I will let you know.

[Blackstar]

it has 195k and has rod knocking

Did any early 95 motors have the dual butterflies on the intake? I am trying to swap an S14 into my 92. I already have the 95 motor that I am stripping down. Is there a way to tell visually if the intake has the butterflies or not?

I believe the CAS is on the transmission @ 12 o clock. If you are re-using your S14 transmission, intake and exhaust manifolds, wiring harness, ecu, and distributor it should not be a big problem. I am not totally sure since all my research was done to put the newer motor in my 92, but it should be the same idea.

[Blackstar]

I'm not using the original transmission cuz its auto, the s13 engine has a 5speed trans so I"m also doing the auto/manual swap. I can re use everything else. So the s13 harness wont hook up the the s14 ecu?

you will have to use the S14 intake/exhaust manifolds, you can just leave the crank angle sensor out if you are swappin an S13 manual trans.

ways to tell if S13 or S14 is by the manifolds, the intake mani has less things than the S13, and the heater core lines are run different from the S14, the exhaust manifold for the S13 is not the same from the S14, the valve covers aren't same for S13/4(S14 has bigger bolts, also has a 3rd bolt on the back between the 2 corner bolts) the upper front cover isn't the same also.

you can tell if the upper intake manifold doesn't have butterflies by lookin @ the back of it, usually S13s have a shaft goin to it, or if you have it unbolted just look @ the runners on the head side.

91-94 ka's had butterflies, 95+ didn't.

there is TONS of information available here on s14 s13 motor differences, so i wont go into them.

you already have the s14, so take your s13 motor, and remove the intake manifold, the exhaust manifold, and the distributor. and if you have it, the ac and its bracket. dont use the s13 alternator, and i might not use the old s13 ps pump.

then do the same thing to you s14 motor. put the s14's intake manifold, exhaust manifold, distributor and other associated parts onto the s13 block that you now have.

you need an s14 transmission, because it has the crank angle sensor in the bellhousing. you also need the mt harness. the only thing im unsure of is if you need an s14 manuel tps.

use the s14 harness.

I read some post saying that the CAS wouldn't affect driveability. I think your ECU will throw a code but the car will function fine. Incase you cannot get a 5 Speed.

Of course my reasoning is that if it was not needed, they wouldn't have gone through the trouble of putting it there...

In my case, I will be using the S13 M/T and Distributor (contains the CAS)

[DjPantsSpecR]

okay, but make sure to use an external coil with that set up somehow.

or refer to this thread, on the front page of the tech page....

and now on the KA page.

Cool, Looks like I just need to swap the auto pilot bearing on the crank, then I can use my 5 speed. Dont clutch kits usually come with these bearings anyway?

[DjPantsSpecR]

also when you put an s14 transmission in an s13, it wont fit until you cut off the metal ring where the driveshaft slips in. after you cut it though, its too short... so it'll leak alittle bit....

so you gotta figure its going to be just the opposite situation depending on what components you use for this swap....

[Zion8561]

OK...now I am a little confused. I thought I had this figured out prior to getting the motor, but I dont want to waste my money building a motor that is not compatible (easy bolt in) with my 92 Fastback and 5 speed.

So I am planning on using an S14 motor (with S13 harness, OBD I ECU, distributor, and manifolds) and the S13 transmission & driveshaft. My previous research led me to believe that this set up would work without much hassle.

Also, why do some sites list S13 and S14 clutches as different items?? I thought they were identical. If they are different, I assume that I go with the year of the motor since that is what it all bolts to, or is the difference in the bellhousing/input shaft on the transmission?

Thanks for bearing with all these variables I am throwing out there.

[DjPantsSpecR]

no, youre just fine, youre putting an s14 motor into your s13. use the s13 clutch.

you will have little to no hassle at all. just use the bare s14 block and s13 everything else until you are more familiar with what youre are doing. like swapping manifolds, cams, etc.
