KA24DE-T Owners

[SR_TeXaN]

For all you guys who have KA-T's(or know people with them) this is directed towards you. SR guys i DO NOT want to start a flamewar so do not reply if you dont have anything regarding to my questions. Ok, so my first question would be what are some of the major problems that are encountered when turboing the KA motor. Second, How careful do you have to be so as not to blow your motor(according to some people they blow rather easy)((SR guys seem to think so)). Third, How inportant is it to buildup the internals? And what would you suggest is most important when building up for the turbo.
The reason i have decided to go the KA-T route is becuase first off parts are cheaper because they arent imported. Second , I like low end torque. Third, I would rather spend the extra 2,500 that i wouldnt have if i did the SR swap on parts for the KA. And last but not least I think i would be happier with the end results.

have you even tried clicking the Search button? come on, dude theres gazilion threads about it, very easy to find. dont be Rick James, bitch!

Well, I had a KA-T car for about a year. Here's a list of precautions..
-Upgrade the timing chain: big money, big problem if ignored. The factory one is very weak, and an upgraded one is expensive to buy and a major P.I.T.A. to do. But well worth it.
-Upgrade your fuel system extensively: I had fuel pump, 370cc SR injectors (go with 550cc just so you dont have to upgrade again later), and a SARD Fuel Pressure Regulator. After all that, you'll need to have JWT make you a better ECU, unless you want to attack a KA-T with an SAFC or something like that, I don't recommend it unless you know what you're doing.
-As far as internals go: knock yourself out, if youre going to tear apart the bitch to do that timing chain, might as well stuff the turkey while youre there. I ran stock internals. As long as you have enough fuel and a good tune, stock internals aren't a problem. There's an SR putting out 500+ hp on stock internals..granted he has Blitz 1000cc injectors pushed to the max
Other than that, its up to you. I went the SR route just because part sourcing is so much easier, now if something breaks..its a problem, but as far as finding aftermarket parts like valvetrain stuff, its much easier and you don't have to drop big bucks on stuff out of the Nissan Motorsports catalog. But props to a new KA-T owner.

[nightwalker]

timing chain? care to tell us why the timing chain is a weak point? I haven't heard of this.


guess you're going to have to change your name now huh, SR_Texan

[russian]

can you elaborate on the timing chain, never heard of that problem before, how much boost u running?

[SR_TeXaN]

hmmm interesting....240KAT, Russian you would be one of those people that need not post.

i will, it looks like you havent even bothered to use the best thing on this angry forum called "search". its a 1 mil. dollar advice, dont be an ass

I agree. No need to post, russian.

70% of the questions posted on these forums could be could be searched for but, what's wrong with getting a new opinion? I bet if he resurrected an old thread about a Ka24det you'd get on him about "bringing it back from the dead". Shut the fuck up.

[nightwalker]

the S13 KA had a recall on the chain because of the top guide, and Nissan recomends changing to a shorter chain (to remove one of the tensioners) other than that, Nissan states that the timing chain will last the life of the engine.

Tell me again why the chain needs to be changed for higher boost instead of redundent comments.

[SR_TeXaN]

Thank you shinhed, I happen to agree with what you said, On a second note Russian I have obviously searched otherwise how would i have came up to my conclusions and questions...

And what is this timing chain statement?

this thread itself lands right under the "No need to post" category.

My thoughts: Don't waste your time or money with the timing chain, absolutely not necassary unless you have 150K plus miles on the motor. Even if you do have that many miles, just replace with all stock parts. I had 80K miles on my block and made 412rwhp and 412rwtq at 30psi with Arias Pistons and Carillo rods. I ran the car at no less than 20psi but most of its life it was 25-30psi. I sold it after 9000 miles and its been an additional year of driving and still no problems. Duy in texas made 545rwhp on stock timing chain, stock head gasket, stock headbolts. I ran all of those components in my car stock as well. K.I.S.S. = Keep it simple, stupid. No need to oring your head or block, waste of time and money.

When building, go to the best machine shop, even if you have to drive out of your way for it. You want it done right and you shouldn't mind paying extra for it. Look into some sort of high performance rings. My stock 99 altima ones were half gone after 9000 miles. I was getting %50 leakdown readings which is not good. All you really need when building is a good set of forged pistons, forged rods, and some good rings, everything else will be fine stock. Another area to spend money in is engine management and tuning. Try stand alone of some sort and spend time on the dyno with an experienced tuner. If you are tuned correctly and safely you will have next to no problems. Make sure your rev limit is not higher than 7000rpms. The crank, and valvetrain will not support rev's any higher.

Replace all heater hoses, radiator hoses and clamps, and upgrade your radiator. Those were mistakes that cost me 2 headgaskets. Get an FSM! It will save you lots of time and money. As for fuel, if you are building a motor for boost, you would be much better off going with 740cc injectors. 550cc's will run out of fuel at about 360rwhp. And with forged internals and proper tuning, you should be way over that. Sard FPR is a good choice.

The KA has only been pushed as far as about 350rwhp on stock internals. If you dont plan on ever going over that, no need to build the motor. T.Y in AZ has been making over 300rwhp on his stock KA for 4 years now with tons of track events/drivers schools.

The KA-T is hands down way more fun to drive than the SR. Torque is an amazing feeling. My SR powered car has run a nearly identical time in the 1/4 mile but it doesnt feel nearly as fast.

If you have more questions, just ask.

[SimpleS14]

interesting post Jay....

so say my car has 185K miles....and I only want 280 rwhp (max)...are you saying I should not rebuild the motor?

ok fuckhead, is it so fucking hard? how come i can find this and you cant?

hey idiot, your village called looking for you. use search and dont dog people helping you out. theres no excuse

Correct. I say dont fix what aint broke. Be ready to rebuild at any time though.

[Bbandit]

jay pretty much explained everything...
just remember.. worry more about your fuel management and tuning..
all forced induction engine will blow up easily if you have poor or no fuel management at all (lean out)..

So now your being more helpful by posting helpful links after I got on your case about being an asshole to another member. Good for you.

There you go again.

Telling someone to search for help ain't really considered helping them. If you ask me, "newbies" asking repetitive questions isn't as annoying as the faggots waiting in the shadows eager not to be of any real help, but to tell them to "search".

Here Mr. Afro-"Russian"....
Zacroy svoy peesavati rot, sooka.

[russian]

nauchish govorit' po ruski, bljadina, huli muchish.

i just pointed out the search, YOU the one that being a prick, so whos the ?

it is also annoying to read same topic every fucking day. give it a rest.

[TurK]

lol ppl on these forums are jerks...but hey gatta deal w/ em ...

[TurK]

o well i like the site so tho i put up w/ it....

[irax]

should i run highcompression pistons for faster power or lower compression for more boost? is there a link to T.Y's build up? id like to see what he has done to get it that high and still have it running for 4 years

[PSI240SX]

irax- His car has completely stock internals.

[DrifutoS14]

if/when i get my hands on a 240sx w/a ka motor, i think putting the pistons in it is a good investment. they're about 400-600 bucks and its just more insurance for detonation. Theres no need for new rods cuz the KA's rods are super beefy stock. couple that w.a nice turbo kit, a set of JWT cams, JWT ECU, 550cc injectors, walbro fuel pump and nismo reg and your set

[Ricer240sx]

can anyone get me more info on T.Y.'s set up?? like what injectors he was rinning and more info on his tuning and what not?? i am in the proses of turb oing right now and i only plan on going with about 300hp maybe 350 so i would defenetly like to hear more about this!!!!

and for the record, i dont theink there is anything wrong with reasking questions that much, and i see absolutly nothing wrong with resurecting new posts cause if u start a new topic it will be very simalar to whats going on in the old thread and then u will get bitched at for asking the same questions and not using the search.

u guys got issues lol

[topwater_fisher]

I think I may have read about T.Y.'s car on NissanPerformanceMagazine.com. I don't know if it's the same T.Y. you guys are talking about, but here is the link to some info on his car:

Interesting Thoughts your people have. PSI240sx nice post very informative.

[kandyflip445]

Do the 740cc injectors allow for a smooth idle with proper tuning?

[PSI240SX]

yes. I have had no idle problems with either my KA-T. or my SR.

[SR_TeXaN]

PSI what are your specs on your current KA-T

ok..but I would be even better off with a rebuild...because there might be moments when I can get boost happy.
