Ka Question

As far as being high-revving and quite safe, stock, go with the SR. Especially if you are on here asking questions about which motor to go with.

Personally, I'd rather have my current setup than an RB swap, to tell you the truth.

AEM EMS KA-T > stock ECU RB20det

Which ever engine it is.... The AEM EMS blows the competition out the water.

Very true, it is also worth as much as my swap...That point being said, doing the ka-t the right way involves more money than probably doing an sr or rb swap....The guys that spend 1k on a turbo ka are the ones who give the engine a bad rap. I went rb20 because it will hold up my goal of 350 horses. I can't say that about the ka unless I rip the motor apart. I've also always had v8 cars and hate the 4 banger sound...Not trying to be a smart ass but i hate it, another reason why I chose the rb, just a better all around sound.

Most of your points are things you've "heard". Im stating Facts, not opinions. I think if anyone sounds like an idiot its definitely you.

the truth is the best way of finding out is by trying both since u kno thats not a possibility for u then u do the second best thing LEARN FROM OTHER PEOPLES MISTAKES now for one ive alwaysssssssss heard of more ka's takin a shit in drifting i seldom here of any srs goin through the years u start to understand a lil more

jdmnismo300 said:
u might say 250 is fine for drifting but what u need to realize is can the ka-T cope with drifting meaning getting hot and being high revving for long periods of time.

The answer is YES. Seems like YOU need to do some research. :rolleyes:

my personal opinion from my research i bought the sr why?
safely high revving
comes boost

I agree, the Aem EMS is out of hand. Unfortunately, it cost an arm and a leg but, "you get what you pay for". :cool:

holy chet how fun we disecting posts now ok ok my turn

im refering to u as a idiot cuz your sarcasm wtf are u talking about lol

research? i have lol u can research a ferrari with out owning one lol dumbass there are strong points coming across in this thread that strongly oppose yours from sources alot more reputable than u lol

and last time i checked my sr "came boost" comes boosted, has a turbo, runs on forced induction etc lol so idk why u laughin lol

but i do commend u ure doing way better u put only 2 smileys in this one high5.......too slow srry
 
Could it take drifting?
Could it take auto-x?
Could it take drag...Yes it is capable of all those things, it just depends how it was put together...If it's a junk build with boost creeping up in every gear, expect problems...It's not like the ka is a case of bad engineering. Look at it this way...
-The sr comes stock with a turbocharger. If you do a turbo upgrade then you need to tune it. If you go cheap with tuning, you'll probably blow the shit.
-the ka comes stock n/a, so any turbo ka-t is pretty much like upgrading a turbo on an sr. You'll need a good tune and good parts. Will it be reliable? Depends what type of condition the motor is already in. I would personally just do a mild rebuild with pistons and a cometic headgasket...and studs. Ring lands are shit on ka's.
I said fuck the ka and bought an rb, but if I had a dohc ka to start with, I would have built the sucker. I didn't want to waste any time with the single cam.

No, you were stating incredibly biased opinions in an insulting and sarcastic manner, as usual.

That's a stretch. I guess if the competition is lower end Haltechs, Microtechs, or any Megasquirt.
 
yeah im just going to swap guys...sr20...itll be better and easier and more expensive...but id rather waste money on a motor that i most likely wont have problems with then wasting money on a motor which i might likely blow by boostin it..and then i might waste more money fixing or buyin another motor
 
they are awd...

What? Your mean Hicas...Only the rb26 is awd. Rb20/25 drop in with a skyline k-member.
Sr's are cool, my freind has one in his car...Like everyone else... soon we shall see which is faster...lol
 
Not really a "stretch" as you say it is....

Compare any stock ECU'd engine with any engine controlled via EMS (of any kind)->(bikirom, megasquirt, calum, haltech, stinger, etc.), the engine with the standalone will always come out on top, because you can ultimately pull hidden power through timing. The versatility of a standalone is unbeatable.

Let's also compare a few factory engines, not that it really matters, but it interests me...

RB25DET - .41 L of displacement/cylinder, oil squirters, main girdle, iron block, forged pistons.
RB20DET - .33 L of displacement/cylinder, oil squirters, main girdle, iron block, forged pistons.
SR20DET - .5 L of displacement/cylinder, oil squirters, main girdle, aluminum block, forged pistons.
KA24DET - .6 L of displacement/cylinder, oil squirters, main girdle, iron block, shitty pistons.

the ka, also has a four-valve pent roof, head design, good for controlling knock. So the KA has shitty pistons, and an ECU that was not meant to handle boost. Thats about it as far as downfalls go.

please discuss.

you made no real good point here. and how can the rb25 have less displacement then the ka? whatever

Apparently I misunderstood you. I thought that when you said AEM blows the competition out of the water, you were referring to all other standalones. Apparently you were comparing a programmable EMS with a stock ecu. Then of course, yes it wins in a tunability contest. I don't understand the comparison but OK.

Trying to mislead people? An SR has a pent-roof combustion chamber also. Not to mention a shallow valve angle (can't say the same for le KA).

But hey, you did forget to mention that KA's have a near perfect rod ratio which means lower piston speeds at a given RPM and a theoretical greater efficiency as rpms increase.

But then again the KA also only has a half counterweighted crank and a long stroke only adds more stress.

actually, the RB25 does have less displacement per cylinder, than the KA.

2.5 liters divided amongst 6 cylinders. (.416 liters per cylinder)
2.4 liters divided amongst 4 cylinders (.6 liters per cylinder)

ever compare an RB25 piston with a KA piston?

Nope, not trying to mislead anyone. I know the SR has a pent-roof combustion chamber, as well as a much more shallow valve angle than the KA.

You raise a good point with the long stroke of the KA, it is another downfall.

Though I think we both understand mechanically what we're comparing here,

Outside of a few small flaws, the KA has a pretty strong bottom end that with good management, can handle boost for extended periods of time.

Before I bought forged pistons and rebuilt, I was running 13 psi (312whp) with the AEM EMS on a completely stock bottom KA, for almost a year.

why would this even matter?
 
Just because something has a longer stroke doesn't mean it's any worse. Just like you stated.

It probably can't handle 9k rpms like the shorter stroke motors could but it has a better torque curve to balance it out. I loved my ka, I just didn't want a high millage motor, I also didn't feel like rebuilding either. There is no "better" engine. They are all good. Just buy an ls1 and be over it, can't talk shit about an ls1......
