what about the KA?

[nissanrcer240]

I was talking to my friend tonight , a fellow 240 owner, and i was asking him when he was gonna get an sr20 in his s14, and he said he wasn't planning on it and that he could get the same or even more speed/power by puttin the money or cost of an sr20 swap into the stock ka thats already in his 240, and that sounded like a good point, maybe i didnt search good enough but i never really hear about people on this board talk about hookin up their KA's , do you all think that you could get the same power out of the ka by putting the 2 or 3 G's into it insead of the sr20 swap.

Well, this argument has been beaten like a baby seal. A lot of people have hooked up the KA. There are many pro's and con's to either engine..... it really just depends on your preference and goals.

[nissanrcer240]

oh, got any good search words or whatever you call them, i cant really find anything

[MaineExport]

I'm not sure that it has been discussed here very much.... or at all. The old boards were littered with the argument, so maybe you could checkout the articles that were transferred from there to here. Also, check nismo.org..... I haven't been there in months, but there was a LOAD of discussion reagrding a comparison of the two engines.

thnk u , good lookn out

[APEXi240]

You know that there are entire TURBO KA, and ALL MOTOR KA sections under the 240 section??

Ooh, I just kind of assumed he knew. I just wasn't sure if the KA24DE-T vs. SR20DET argument had been discussed here or not.

[APEXi240]

Yeah there are a couple of threads on it. Don't ever assume, peoples obliviousness (sp) scares me sometimes.

[InstantRice]

yeah there are alot less compared to the old forum though

[Dattebayo]

hmm... maybe us ka finatics need to bring the issue up again. I still think that the ka is a more worthy alternative to the sr than anything else out there. Why just now i have my ka up to silvia hp specs (with more torque on the low end) without a turbo AND for less than a grand. It really is somethong to think about, but i guess its only if your a do-it yourselfer. you have to think about the bottom end of both engines at first. There is no way aluminum can surpass cast iron quality or sheer brutal ability to push the psi up on a turbo. SR's have the unfortunate tendancy to crap out after 550hp (somebody correct me if im wrong) unless you put a crapload of mods into the motor. Anyway im just a n/a kinda guy so you wont see me doing this kind crazy sh*t.

less than a grand?? CAI--170Apex-i N1--450 or so shipped2 electric fans--120cams--900 for everythingflywheel--350--------------almost 2000....sr20det from daunt--2200

sr20 install-2k

you forgot that

[red240ne]

actually 1000, but why have someone else do it?? it's not as fun that way. then you can't be as proud of your car.

"less than a grand?? CAI--170Apex-i N1--450 or so shipped2 electric fans--120cams--900 for everythingflywheel--350--------------almost 2000....sr20det from daunt--2200"

quote from red240ne

yes the apex-i was that much

the cai was custom bent by yours truly for $40 from emt from electric supply house

the electric fans came from an altima ($15 at junkyard)

the cams did cost like 300, but i milled the cam towers with my friends help ( $0 )

oh and hey the flywheel from fidanza was only 309 tax and everything when i bought it from altered atmosphere in gaithersburg, MD (the best import shop in the area i swear)

so I WAS WRONG it was like $1100 but still better than $2200

[red240ne]

i wasn't necessarily doubting you, i was just wondering how you did that so cheaply.

[APEXi240]

There is no way aluminum can surpass cast iron quality or sheer brutal ability to push the psi up on a turbo. SR's have the unfortunate tendancy to crap out after 550hp (somebody correct me if im wrong) unless you put a crapload of mods into the motor. Anyway im just a n/a kinda guy so you wont see me doing this kind crazy sh*t.

crap out after 550hp?? WTF, if I'm pushing that much power I won't really care what kind of block its on, that's already more power than I want anyway. And you need to put a "crapload of mods into the motor" to even hit 550 anyway. But if you wanna wax about it, there is a stock block SR that was pushing 403 at the wheels, Mattback posted the dyno. The Signal S15 puts out over 600.

KA v SR can never be determined because its subjective. Its what you like more.

[Dattebayo]

what about the reliability of that "stock block". Thats what im talking about. the sr's are not built to tolerate extreme power like that and you could only get a few hot runs out of a setup like that. You can say what u want but ka's do have a stronger bottom end and you know it (unless youve never seen a ka). If you build your ka correctly you can go much further than you can with sr its a known fact. Power bands are different and i know but the ka will prevail in the end, turbo or not.

[fiznat]

hmph. this is not what everyone said when I asked pretty much the same thing last week.

(http://www.nissaninfiniticlub....=8092)

Namely, the general opinion was that I couldnt even come CLOSE to the SR's specs without "a huge shot of nitrous," and a bazillion dollars of bolt-ons.... how are you guys making it sound so easy now??

[Redline240]

well i get to do both, cause i'm swapping my KA into an old 280z that i'm building for racing and dropping a SR into my S14.....my question is at what point is an engine too high millage to rebuild? it's got about 175,000 KM on it, so about 115k miles, and if i build up the internals wouldn't it's be almost as good as new? also on a side note how expensive are are the VGTT i think that's what it's called the 300zxTT engine anyway? i figure that would fit my 280z......

[Exar-Kun]

its a VG30DETT, it wont fit. the turbos and manifolds would be, literally, in your wheel wells. Im sure you could spend a ****load of money and make it work. a few GA Z club guys mused about it, the DOHC heads, and twi turbo block/manfiolds make the engine too wide to be used in the older Z's engine bay.

a 400ci V-8 fits nicely though, go figure.

thanks for the info, and yeah a guy near me got a chevy 350 small block in his running 12's.....but i'd like to stay nissan....

[Dattebayo]

yeah no sense in swapping to american (i think its a frickin crime to swich to domestic power). There are plenty of options for your 240 that are easier and far more satisfying for street and strip handling anyway.
