hmm im new to the 240sx world kinda but ive been doing alot of reading in the newbie section :biggrin: . I don't think it was said so ... whats the difference between a KA24e and a KA24de. And i think ive seen KA24det or a Ka-t somewhere also. but like the only thing i know is that KA24E are stock, atleast for 240s in US ... i think. lol don't eat my ass out if it was already posted somewhere else ... i didn't see

KA24E- SOHC 89-90 models
KA24DE- DOHC 91+ models
there isn't a real ka24det.. no turbo models were never made in the US.. but u can get an after market turbo and make the KA24DE into a DET.. the T on the end jus stands for turbo

hmm okey. what would you consider a better engine over all ... like comparing the 2 engines to each other, pros and cons.

which one is more availible ... like would be easier to find if i needed just the engine ..

Thank you

DOHC is better then SOHC.

i dont consider 1 better then the other. I'd rather have a SOHC then a DOHC tho.

hmm lol ... okey what are the stats ... not to pester you people. I don't entirely know what SOHC or DOHC means either ... but what would you consider better for what ... thanks

Ok so you're new to the whole car world, not just the 240SX world... Single Over Head Camshaft and Dual Over Head Camshafts. KA24E has like 140hp and KA24DE has 155hp.

well no not really i just never found out what those terms ment. thnx

KA24e KA24de

KA is the engine series, 24 is the displacement in liters in a kind of scientific notation; 24 = 2.4 liters displacement. It's that way with most all nissan engines, heck most engines in general, to my knowledge.
The "d" stands for dohc, the "e" stands for electronic fuel injection. And if there is a "t" or "tt" after all of that it means it's either single turbo or twin turbo. I think that about explains that entire subject.

So therefore, the difference between the KA24e and the KA24de, apart from the "d" is that the former is only sohc, and the latter is dohc. Mainly, this becomes important to your own tuning tastes as dohc engines are easier to manipulate because two camshafts mean independent adjustment of intake and exhaust, while the single shaft controls both at the same time.

If that doesn't answer your question, I don't know what will.

The question was already answered, but thanks for the input, doctor.

dohc is definitely better than sohc... twice the control of intake and exhaust valves are a plus to any 4-cycle engine operation... that's already a given.

More valves are better for street use. "Better" really depends on how you are rating them. Equal opportunity engines. If anything, the DOHC has more aftermarket support.

i dont consider 1 better then the other. I'd rather have a SOHC then a DOHC tho.

Sure... why not



RB = Racing Breed
KA =... Kick Ass? :dunno:

hehe wow thnx people. that about answers all my questions. but you can argue which is better .. hehe more info for me. now i just have to save money up for the actuall car lol .. that will take a whiles ... a long whiles

Actually, the question was not fully answered, so I figured i'd end the discussion.

All these douches lied to you... none of that is true... Ill tell you the real differences... but in exchange I demand the girl in your Avatars phone number and address.

haha well ... hot sh*t huh :naughty: . Hehe shes a japanese jpop artist ( if you didn't know and is just being sarcastic ) hehe if you wan't i can give you like 2000 of her pix somehow. I have a shit load of her made for avatars. Shes Hamasaki Ayumi. If you want a hot girl to look at, google image Mai Kuraki. Shes hella hot. I have a ton of asian photo books on my computer.

But yeah okey tell me more about the engines. I'm only 15 and im tryna learn as much as I can about cars so yeah you know the deal :biggrin:

ps ... who wants to go to jgtc and the d1gp but doesn't have any money. I live in seattle washington, no job ( means no money ) but i hella hella HELLA want to go. sigh ...

15? Dude, don't you need like parental consent before you can leave the state?

DOHC engines will always be superior to SOHC, SHIFT said it best, more control over tuning.

< 17... coming from Texas...

ps ... who wants to go to jgtc and the d1gp but doesn't have any money. I live in seattle washington, no job ( means no money ) but i hella hella HELLA want to go. sigh ...

Where is it at? i live in Vancouver Washington, let me know if your comin down here...

There's a vancouver Washington? I'm going to Detroit for the auto show this winter, from Montreal it's not that far, I wanna go to a NOPI event to, but I dunno if there are any I can drive to in under a week...lol

hehe kinda seems like the focus of this thread changed but yeah its worth it ... the race is in the California Speedwaym in Fontana California. Don't worry they won't being going in a stupid ass circle, the course has a half circle and then like 21 turns inside the track. So yeah it would be f*kking tight man. 50 bux for weekend pass. And then like on the 19th, ( same as second day for jgtc ) D1gp is just in Irwindale Speedway. Not so far from California Sw. Sigh ... I don't think that i would be able to get a ride down there and i don't think imma have enough for plan tickets. But shit my friends brother has been waiting for this and if we go, like his aunt is just 5 mins away from track. I know my friend will probably go because hes spoiled but still man its like ... going to be a great page in racing history for all the people who go.

dohc is definitely better than sohc... twice the control of intake and exhaust valves are a plus to any 4-cycle engine operation... that's already a given.


not really, the other camshaft on a SOHC still controls the valves, to tune it and change it you would need a new cam, same with DOHC but you would need two cams.... I don't think your statement holds any water

well with dohc you can controll exhaust and intake side seperatly, while in sohc you can controll intake only as a whole, so if you want to set timing on exhaust a few degrees more retarded or advanced your intake timing will change as well. Most of you probably knew that though.

hmm alot to think about ... but like which one would be cheaper .. just wondering. Which one is more reliable .. if thats a good question .. like what would be the down play for the engine in general, whats the best things. not just dohc and sohc. i learned what they ment but i jus forgot the meaning lol

Actually the reason DOHC is better than SOHC is cuz it allows more valves, you can't find any SOHC with more than three valves per cylinder, but with DOHC you can have 5 valves per cylinder, which has a better advantage in tuning. I haven't seen any supercar with less than 4 valves per cyl for the longest, the new F430 modena uses 5 valve, and the Ford GT has 4. Sohc are the next step down from DOHC, then come pushrods, why are they still making pushrods anyway????????????????

Shift is right, all F1 engines are DOHC, Nascar still has some SOHC and some pushrods.

Because pushrod is oldz skool!!!!

What is wrong with this picture?

Nothing really. You can run more boost safely with the lower compression ratios of the early KAs. One cam is cheaper than two.

No actuall the guy is retarded.

"you can't find any SOHC with more than three valves per cylinder"

Honda D series

"I haven't seen any supercar with less than 4 valves per cyl for the longest"

Mercedes still uses in quite a few cars

"then come pushrods, why are they still making pushrods?"

I dunno about you but I wouldnt fuck with a Z06 or modded SS

"dohc is definitely better than sohc"

Aruguable but I agree.

I love the ZO6 and SS, but I think it is time they upgraded the Tech on those dinosaurs, some DOHC, improved intake and cooling system, and some other stuff and voila, a good engine.
