The Perfect Ka24E Build Info Learning<3

[LadyJdm]

Hey everyone!

I'm here to start a new and FRESH new thread for Ka24E LOVERS out there!

My other thread (ka24e how to gain torque)

Was pretty lame, but it taught me to do more research and see other people experiences in the field of building a nice Ka24E build<3

not many people out there fully build ka24E that I see but I'm here to get info and also have ideas for my Ka24E build

so let's start on what is the RIGHT 1st step of parts to upgrade on a Ka24E motor 1st!

I know there's alot of ways to start, but what are they key parts that a Ka24E motor Lacks & Gains Can Be Fixed And Solved!

I say 1st from hearing from other O.G builders...

"IF YOUR WORRIED ABOUT MONEY, THEN DON'T BUILD YOUR MOTOR"

every build takes time and money to even make a good motor turn out "DAMN!" so I say for one..

Ka24E motors lack the PISTONS of the motor,
Like Ka24DE motors they are better equip with bigger/better pistons of course, and that's where a ka24e lacks power, to gain that extra 10-15hp for stock Ka24e Vs ka24de motor has.

but also when you add that to the list you have to think about fuel injectors/fuel bump/fuel rail ETC to gain max performance if you really want to see the numbers

so 1st question! what is the best performance pistons out there for KA24E? even I'm thinking which to pick...

Arias, Cp And Tomei ETC. what is the right compression for N/A or turbo Build???

I want to go N/A Build On My KA motor but u can also post up things for turbo as well
(i'll go turbo after i build N/A)

Thanks For Reply's!!!

[h2v7]

tell me about the CHEAPEST and more RELIABLE bolt on turbo kit for ka24e

fast, reliable, cheap
pick two

[Weedm]

building an n/a single cam for what? with the amount of money you pour into building a half decent single cam to gain 20 hp, you could have a nicely done SR that is both reliable and fun.

im glad i never finished my ka24et build.

[SochBAT]

Rebello should offer nice parts for the KAE for replacement. I would personally lean towards the CP Pistons. tons of guys running CP pistons can't say enough good things about build quality and their performance. Then again, Arias has been in the business longer IFAIK.

[iamtheyi]

If you want to know how to build a KA24E then go on the KA-T forums. They have a section dedicated to it. Most people on Zilvia are diehard SR20 lovers. Not that it's bad but they are not going to have the information for you most the time.

[Pandapants]

The ka head is restrictive, worse on the single cam. Open it up with a port job and throw on a big cam. That's where you'll see the best gains.

CP pistons are pretty nice, mmm ill check em out more they are about the same price as Arias,but seems like CP has more varity or compression rates high and low, so they must be pretty good to have a wide varity for N/A and Turbo build, thanx soooshi!

THATS WHAT I WAS THINKING! >_< through some nice performance camshaft/Pistons and the KAE will be set for a good performance!

what do u guys think are best for camshafts out there??

I know eh? lol well i know there people out there that hate the idea of building a KAE motor, but i'm just sticking with what i wanna see really accomplish, and also in the long run be a reliable built track/daily car :)

honestly there is no fast/cheap/ depending on how u use ur motor reliabe turbo out there lol i found some that are like ebay brands that can gain like 100hp-150hp and max psi can reach to 7-9 but not bad for a daily :) its like $500-$1000 for the whole turbo kit , i think it's called, CX racing. but thats what ive seen thats seems pretty good for the price and what u get for it :)

but like i said, depending on how u use it u can blow the turbo easy, ive seen it happen alot on KAE motors, better approach with a N/a build, like pistons/cams/camshafts/fuel etc and then TURBO THE ITCH - & you can boost as much as u want! without little worry :)

[Pandapants]

O and J performance makes some nice cams for the single cam, better than jim wolf.

[LadyJdm]

oo i'll check on the O&J performance, if there better then jim wolf then they must be pretty good :) what motor do u have pandapants?

[s13 @ fullboost]

Arias pistons FTW Lilly I can get you a fat discount on the pistons I am close friend of the arias family. Also N/A will get you no where if you wana stick to the kae platform your going to need boost to make it worth while at all. hit me up when you wanna come by and pick up that exhaust

[alexandria]

You might want to mention that if you do an N/A build with high compression pistons you dont want to just slap a turbo on it and call it a day. You might want to get some low compression pistons, just my 2 cents.

fo shure! forgot!

high Compression build is Better formatted for N/A build!
and
Low Compression is better for Turbo build!

thanx for pointing that out alexandria! (http://zilvia.net/f/members/alexandria.html)

but hasan! ill check on those pistons fo shure! :) love discounts!<3 and ill see if i can get the exhaust today :) ill hit u up!

[s13boy89]

single cam is just fine in stock form miebuilt ne was rebuilt.headers.intake.lightweight flywheel.nismo r3 camand it ran titts

[LadyJdm]

yeah fo shure! im thinking of doing something else now, but im still going to build my single cam alittle so it has a punch to it :)

but if u guys go to the track and drift ill see u around!! just look for a 240sx coupe white with a ladyjdm sticker on the driver side front window! :)

notice how the title of the post is "The Perfect Ka24E Build Info Learning"
it is a post for those that actually like the KA, so your SR blasphomy is not wanted or needed here.

THANK YOU!!! lol yes only KA-Lovers Here<3

but when i get my pistons/camshafts/cams ill post you guys up on my dyno test!

[240sohc]

any update on your upgraded parts? pistons or camshaft for that matter?

[jr_ss]

Even then, the KA24E is a waste no matter how you roll the dice. It's like building a CA18DET, or an RB20DET. Atleast upgrade to the DE, it's a better platform to begin with than the E... Either way it's your money, you're allowed to waste it as you see fit. I just think in the long run and reliably speaking the DE would better suit your needs.

I have been running the CXracing turbo kit for the past year, on a stock motor @11psi

i have to say the kit is great car feels amazing, 50trim turbo is the perfect size for fun and still maintains off boost civility. but to anyone who runs the kit, do the smart thing and get all the complimentary parts that go along with installing a turbo kit. ie: fuel system and a tune and clutch.

i have yet to have the car dyno'ed but plan to have it done within the next month or 2.

everyone is correct the 2 bottle necks the sohc have is the head and the pistons.
a mild port and polish and cam combined with turbo will really wake the motor up.

as it was suggested visit Ka-t.org alot of great info and very helpful people

[240sohc]

Anyone out there using the jgs precision turbo kit or their manifold for that matter?

damn nice! 11lbs for a daily is pretty bawlesy lol but nice! im going to go turbo soon also might be getting the god speed and upgrading the turbo see how that goes :)

[mikey976]

im not aware thet godspeed makes a turbo kit for kae, all the kits you see on ebay are cxracing.

im also tuned via nistune/460 injectors/n60 maf/LC-1 wideband,
7psi was meh the provided WG with the kit is crap. i bought an emusa and tial 7+4psi springs. 11psi is nice the butt dyno likes it, 14-16psi should be sick (with the addition of meth injection)

[LadyJdm]

oo heck yeah that sounds good already! yeah god speed has turbo kits just newly made for ka motors, and they also sell the replacment turbos for them also *PLUS!*<3

and nice how much hp you pushing? 200-250hp??

[mikey976]

just looked up the price on it, holy crap $2400 bux!! i paid 1100 shipped for my cxracing and its the same exact kit, only difference is the elbow/dp on the godspeed is 3 bolt vs 2 bolt on mine.

as far as my power, it remains unknown till i have it dyno'ed but some of my friends are speculating i may be close to 300 being i raced a 2008 Porsche Cayman S and took him by 2.5 cars. i can get a more accurate estimate once i take it to the strip and get a few passes in

[LadyJdm]

yeah they are a bit pricey but u can find them for 1100-1500$ when they come on sale, i saw one on ebay not to long ago for $1000 bidding and they got it for $1300 :) not bad i would say for everything! but cx racing is nice though i love the way there welds are looks thick and strong :D

but

dang! nice that means u should be around 13 secs on 1/4mile! :D
not bad for single cam<3 love em!

im thinking 1st to build mine all N/A maybe hit the 250hp mark then go turbo and reach up to 350-400hp with turbo and see how that goes :) need that power for drifting!<3

your gonna be extremely hard pressed to squeeze 200whp out of a N/A kae, there is a company that sells kae crate motors putting out roughly 300hp, but their life span is counted in hours of use not miles not to mention a 6k+ price tag if i recall.

i priced a built bottom end (assuming i do all the work as usual)

weisco pistons with eagle rods = $740
ACL bearings = $80
ARP studs for main and head = $200
cometic head gasket = $80
hot tank and general block inspection = $150 (depends on your machinist)

roughly $1250+ the cost of the cx racing kit = $2350 still cheaper
now add in rx7 460/550's / nistune / z32/n60 maf your just cresting $3k
then you have to have it tuned say $3500 (with out price of clutch)

a built head will run you another $800+ you'll have a motor capable of 400+whp (depending on tune) all day long

[LadyJdm]

hmmm :) then i am bout right then 400 whp is enough power in a single i say, i already beat daul cams pulling up hill from 2nd to 5th gear and im about half a car lane away :) not bad with bolt ons :D

but have u bore u head already??

[TheEightyNine]

Ive decided to stick with the sohc since it will be easier to do than any other swap. Plus the sohc should be plenty for what ill need it for. A strong running reliable daily driver that i can take out to the track every so often.
So ill be buying a spare block to do a stock rebuild on.
then i plan to use a OandJ cam. Cant decide if i should go with the hydralic stage 1 (266 Duration 435 Lift) or stage 2 (270 Duration 445 Lift). I want the best bang for my buck so im tempted to go with the stage 2 but do you think ill loose alot of the bottom end tourqe with the stage 2?
Along with the rebuild and cam ill be running a 4-2-1 header, 2.25 straight exhaust and plan to relocate battery to the back and make a custom air intake in place of the battery. Once ive done all that i plan to get a tune depending on how much money i have left after everything. I know its not necessary but i wanna set it up the best i can with what i have.
Also just curious once i have the engine ready to swap should i be going with a different spark plug gap and what should i do timing wise with a setup like this? Stock?
Thanks in advance

actually im in the middle of a rebuild since my last post. engine blew cyl3 driving from North Jersey to Connecticut for the 240sxMotoring/CIP meet last month.

KAe's are tough bastards, my engine went about 20 miles before the meet, and its roughly an 80 mile trip i drove her the 20 to the meet on 3 cylinders and then the remaining 80 miles home and she still would hit 3-5psi boost when i needed it. I love this car it refuses to die

i have 2 engines for it. the one thats in the car now with a bad cyl3 and a spare block i just bought.
i am doing an OE rebuild on the spare block so i can get the car running again. then i am doing a fully built block with the motor thats blown.
depending on the condition of the cylinder walls i will bore it out as needed otherwise stock bore is more then enough. I hope to have the fully built motor done by xmas

plan is to run 20+ psi with it tuned properly

good post:aw::aw:

[TheEightyNine]

mikey- How long have you been running the kat setup before you ran into trouble?

[mikey976]

mikey- How long have you been running the kat setup before you ran into trouble?

i installed the full basic january of 2k10, ran the kit with only a 10:1 fmu and timing retard at dizzy @ roughly 8psi but would spike as high as 15 WG was shit, for roughly six months, mainly because clutch gave up.

at that time i pulled motor, switched to a rebuilt P&P head i had for 2 years in storage, installed stg 3 clutch, RX7 460 injectors and replaced the shitty WG with an emusa WG, at that time i ran a @7psi tial spring and ran fantastic. then after a long trip the WG bolts worked there way loose so i figured since i have the WG off let me up the boost, and dropped a tial 4psi spring in. and ran 11psi up until last month when it blew. about 4 months ago i finally got around to installing my n60 maf as well

caught quite a few people off guard with it, especially cause i have the WG recirculated, it sounds like a N/A ka till about 2800rpm when it spools.

[zneubauer]

check out the Nismo catalog, they have more for the single cam than the dual cam. I support you 100%, I hope to see one badass sohc.

[superdrifts13]

which cam would work better for ma ka24e has 4-2-1 header cat back under drive pullys cai
woul the o&j stage 1 or 2 be better with stock valve train and stock pistons

[Shift n Drift]

jwt cam and ecu tune

[iveexcaped3]

old thread

[rcdad123]

ok. i need a 10-1 boost dependent fpr and a t28 or a t3 and it can handle up to 11 psi. looks like i will be going turbo sohc then.

[moth]

i love this thread

[h2v7]

hi mr bump lets get some more sohc love in heree

not my pic some guy on forum pretty sure

[RedTopKA-T]

my ka24e-t.

[wangan_cruiser]

my ka24e-t.

how much psi u running?

what are the specs?

[RedTopKA-T]

Ka sohc stock block 47k miles ,Gsp t4 .50 trim ,550cc venom injectors ,Z32 maf, 38mm wastegate , hks knockoff bov,Nistune
Dyno'd in at 251whp @ 10 psi with a couple of minor boost leaks . goin back for 12psi when the leaks are fixed

[Papi Sucio]

anymore info/updates to this thread? i keep coming back interested to see what you guys have done to your single cams lol im thinking about rebuilding my first kae with a blown head gasket but i cant decide what mods to do to my engine also.

[RedTopKA-T]

Here's my fully built ka. Still waiting on a few parts..

[NWsally]

Quick question. curious as to if its possible to use the SR light weight pulleys on a KA24E with out doing any mods or if its even possible at all. I tried to research. but only came up with one thing and I just want to confirm whether or not its possible.

[mikey976]

hey redtop that's a sexy single jingle you got there but I hope your not running a stock oil pump with all that line. highly recommend you use a 78 datsun l28 pump bolts right on and will give you 20+ psi additional oil pressure.

and yes you can adapt Sr light weight pulleys to kae a few did it on ka-t.org
