Ka valvetrain

[Kouks]

I have never heard this topic over here, so I thought I would bring it up. The guys on the ka board, are always talking about getting ca/z32 valvetrain. So any company that makes valvesprings for the ka will work on the ca.....(supertech,crower, blah blah blah, there are a bunch now.)

did anyone else know this, cuz I didnt.

Heard the same thing, a KA guy using CA cams.

Would be great if someone knew 100%. You got chain vs belt but probably just different wheels in the end.

[zero_gripS13]

usually it is ca cam spec reground into ka cams for ka-t oowners...

and yes ca/ka valvetrain is interchangeable..

[biosehnsucht]

quick note to prevent future confusions: you are of course referring to the KA24DE not the KA24E.. which has a totally different valvetrain

[float_6969]

The KA DE lifters are a different diameter aren't they? And the KA motor is considerabally longer, so I wouldn't think that the cams would interchange either.

I'll find out.... I have a spare head... and a spare KA. Just give me a couple days or something.

[Kouks]

Since the ka thing is blowing up over here, finding out exactly how much we can use off of the ka's valvetrain would be helpful. Yes of course I meant ka24de, but thank you for clearing that up for the people who might ACTUALLY ask that question.

I have heard of kade guys running 240/240 which is two ca intake cams.....even 248/248 for them is pretty lopey. the cams and valvesprings i have heard work.

Do lifters, and retainers work....that is the question....

[zero_gripS13]

ive read about this from about a year ot so ago..

valve springs, retainers work

cam specs work for ka24de-t (reground with ca specs)

lifters im not sure..

c-rad will be able to answer with some emasurments

hrmmmm if ca/ka are changeable my question is why? why swap ka junk to a ca. I have a ka.. and let me tell you guys your ca has more head flow and revs higher on the stock valvetrain.. why swap ka junk on it? or why even bother wasteing the time to find out if the head parts are really changeable, cuz i think everybody should know stock ka head flow sucks monkey balls and valvetrain sucks.

Cause it´s nice to know that you can find CA parts easy and cheap in USA when something goes wrong.Maybe some guy need cams for regrinding or a broken valve spring?

I only look at it as less expensive aftermarket parts for us!!!!

[boost_boy]

I wouldn't go too wild on this KA valve train phenomenon because I'm kinda with S13 240sx on this one. I don't think I want anything from a cheaply built motor in my car. The KA(DE), SR, GA16DE, QG18DE, and QR25DE are only econonmically built. I don't care if someone says it fits, but it is for the KA, I'm not touching it. Stick with the components from the VG30DE series or purchase true CA pieces if and when they are available.

But seriously though, what is wrong with the components from the nissan pulsar. They are the same components used in your CA18DET and the CA18DE's can rev to 8500rpm just like it's turbo'd brethren. Are any of you seriously planning on making power past 8000rpm? And even if you did plan on making power that high-up, your car would be no fun on the street. Take my advice and stick to what's available for us. We don't need no more myths rolling through our beloved CA forum.

Dee = Mythbuster!

The only interesting thing would be if they shared the same part numbers.Not only fit, that´s dangerous but would be nice to have another source of parts.

CA cams in a KA? Belt driven -vs-chain driven? So how did he pull this wonder off? When he could've easily gone and had his cams reground or bought some off Jim Wolf or someone. It would be sad if someone went through all the headaches to use an already low end power-deprived engine's components to try and make there's something it is not (rev-happy). This don't sound too smart to me, but that's just me. I believe in innovation (no doubt) and I commend all those who go a step further into the unknown, but I just don't see the use of CA parts on a KA. I guess we'll be looking to make CA24DET? Come on guys, if you have any knowledge about cars and mechanics, you'll discover that this is crazy (probably not impossible). But if they are trying, I sure as hell would love to see them pull it off. Imagine trying to put the SR head on the CA. What a waste, huh! I can go on, but hopefully others feel the same way.

[knightrider]

why would you guys want to put KA valvetrain in your CA? if you are looking for aftermarket, look at the VG30DE. the VG, CA, and RB share the same design and valvetrain components, lifters, springs, retainers. theres plenty of support out there already for the VG. if you want springs and dont wanna have leftovers. give JWT a call, we sell sets of 16 VG30DE springs just for you CA guys.

hahahah knowledge is power yes but not from a crappy ka to install into an already built jdm motor swap. and buy the way if you want cheap parts for the ca18 in usa.. why not just go to a damn junkyard and find a non turbo u.s ca18de for parts!!!! i'm sure the parts will be changeable more than likey than the ka, and not to mention they are better! I have seen single cam ca18's and twin cam ca18's usa model's but non turbo in junkyards all the time.

[Kouks]

I think youre taking it the wrong way. My thoughts on this is if they can use some of our stuff(like valvesprings) then what is so bad about buying supertech double wound valvesprings for the ka and putting them on a ca?

Will they not work as good as the super jdm tight vg30de valvesprings? no doubt I would buy the JWT ones, but the ca most people seem to not know that much about. With the aftermarket support for the ka growing in leaps and bounds, couldnt we take advantage of some of the stuff they have to offer.

I highly respect your opinion, but i dont see the bad in knowledge, and opening up our choices for more aftermarket support. That leads to lower prices for us.

Kouks, don't get into this too deep, dude. I'm not slamming on you for trying to help out, but at the same time, I don't want some of these kids on this forum to start misinterpreting your gesture and start asking silly questions like "a CA24DET" . I've seen it happen and I'm merely trying to suppress any foolishness before it begins. If the KA's components do indeed fit the CA, then there you go. I personally would rather purchase something from a more performance-oriented nissan engine than one that is not. Everyone is trying to develop the KA and trying to take advantage of it's huge displacement and cast iron block, but I don't see a whole lot of reliability in that motor nor it's components. So if you want to try that stuff, go for it. But it is essential that members don't read too deep into your post and start asking silly questions (Feel me).

Take a look on the ka-t.org forums. There are numerous people making 400+ to the wheels on the stock bottom end. The KA isn't as bad as everyone makes it out to be.

I love the CA as much as everyone else in this forum, but you can't deny the KA when stuff like this is being pumped out--

Eye candy All fine to the eyes, but you have to stick to the topic being discussed. Why would you want to use stuff crafted to help the KA to be more than what it is when you already have what the KA is not "A performance engine". I have friends with 500+ and 600+whp KAs, but you actually think I want to got through half the crap they've gone through only for it to eventually let go "AGAIN". They've spent more money than you can think of and have gotten good dyno power.

Hell, one of the ka powered 240s are doing low 11s consistently and I can't argue that. Each engine has it's plus and minus issues, but the arguement was in refence to KA using CA parts and vice versa. Good to know, but I personally will pass on products designed to help the KA. Failure is eminent because you can't polish a turd . It is what is and no disrespect to KA-t owners. Keep the revvs down and the ka just might be a good medium duty platform, but it ain't no high revvin monsta', so most of them cats need to stop with the thought of even borrowing components from the CA or VG.

Goes to show you that even though they have great torque and produce good power pound for pound, the owners are still not happy because they also want to have the rpm advantage and that schitt ain't happening.

Gotta have some fun, Mike. Pound for pound the KA will romp all over the CA in some areas (contradictory), but I still think it's a dyno engine only. The SR20 has been built by some to put the smack down on the track. The CA has been built has done well in it's own reicht. The KA is the ultimate street baller 4 cylinder as I watched a friend went street sweeping with his S14 smoking all kinds of turbo'd ricers. But keeping it real, the SR has stole the show on the track. It has been proven time and time again by many of tuners and DIYers alike, but the KA has a handful who've gotten great power and decent track times, but they always disappear from the scene. No consistency, just like their engines. And BTW c-rad, I've seen waaaaayy too many bling-bling KAs that start out pretty and the next thing you know, a rod is sitting outside the block the tongue of a dead dog after he got smacked by a 1990 nissan sentra doing over 160mph on the highway .

Yeah, the KA is only used in King Cab trucks here, would never think about using it, actually got a bit confused when I saw the KA forum.It´s different in USA when you got the KA in all 240`s, most people probably want to turbo it to drive around and pyyyyysch but I would take a CA or RB before KA and SR any day of the week! These engines are a lot more race, every internal part is race stuff if we think about the age of these engines.

Displacement is the new craze in the U.S. ! People were throwing away perfectly good KA engines for an SR20 swap, but now things have changed. People are only now seeing the opportunity to turbo what they got and enjoy the extra torque, instead of spending $2000+ U.S. on an engine that have a disgustingly inferior valve train. The CA DOHC engines are possibly the only nissan 4 cylinders that came standard on 5 or more of the products as either standard or optional. And is the only one that is interchangeable between FWD, RWD, and AWD platforms. Nissan obviously thought so highly of their marvelous power plant that they gave it multiple duties. History and the facts as well as its assigned duties are all the credentials the CA needs.

Now the KA is a work-horse that will not go out the door quietly. It's been done in FWD and RWD and have proven to be a tug, but that's exactly what it is "A tug" and that should not be confused with a racing tug, because neither the words "Tug" and "Race" should be in the same sentence, but whatever. To each his own is the way I'll end this.........

Not to be defending non-CA motors but what about the DOHC SR? It came in FWD, RWD, and AWD platforms as well. Regardless of that I'd still take my CA over any other Nissan motor (with the exception of the RB) any day.

The point I was trying to make is the fact that the RWD and FWD/AWD SR20s can't be interchanged. However, after further thought, the SR20 was used in a few models itself, but still not swappable from front to rear wheel drive. If you guys want to talk about a serious engine that's been over-looked, let's rap about the FJ20DET. That thing might beheavy as hell, but it sure was a work-horse in itself. Folks in Aussie-land still use this thing on the strip and from what I've seen, it is a wicked devil!

Deffinatly. I saw a complete FJ20DET with wiring harness and everything on ebay for 1500 shipped, I was very tempted to buy it and put it into my S13. Too bad just like the CA, there's not much aftermarket support. It really makes me mad that just because the CA and FJ lack publicity, people think it's a piece of crap. Oh well, I just like my redline and maitence bills do the talking

Boost Boy your a joke and its actually a waste of time banning us, if you actually look during our bans we still registered and posted. Thanks to your lovly nico members they taught us how to beat the system and conceal our internent identities. So you can ban us but I'll be back in 5 minutes.

Oh yeah, thanks for blowing you and your boy's cover. We'll be on the look out for any new members trying to post in the CA forum. I wonder where you're gonna talk about the CA as a newbie, in the KA-T or RB section (I think not) .
