I appreciate how he kept the zenki front end.

Fun fact: All KAs found in the cars had blocks casted in Japan. All the truck engines were casted in Mexico for the most part

Aaron I have been building these engines and doing this professionally for years and this video makes me really happy. Thank you for doing this and showing all the kids at home what a viable engine and platform these can be.

KA’s get a bad wrap for no reason. Mad respect and great info ✊🏽

I appreciate these types of videos. Learning about any sort of engine intrigues me.

screw it. a 250-300hp KAT sounds fun.

I love these high quality info engine videos that comes from experience from owners and specialists so thank you

As a owner of a fully built KA-T with a standalone, I approve this video and all the information. Parts and cost are pretty much on point. Great job!

Finally... I love my KA-T. 226whp/246lbs/tq with an eBay T25. I just put a gt2871r on it, converting it to speed density next week (Nismotronic SA)

Of you jump the intake cam 1 tooth on the chain you change the powerband of a ka. Instead of running out of steam at 5k rpm it will pull hard to 7k. I found this out 20yrs ago

This was such a fun video to watch! The level of detail Spencer knows about KA's is crazy! I loved hearing him explain the different stage builds you can do, and in a quick and simple way too.

God dammit now the prices for ka’s are gonna sky rocket😭

That was great, I listened to it at work like a podcast. Valuable info that not everyone is happy to share! Keep on shredding dudes

Super glad they mentioned the surge tank upgrade! I've had a KA-T for about a year now and bleeding the cooling system has always been an issue until I installed the swirl tank. Definitely a must do for cooling upgrades.

He said handicap of an engine. If you don't like it cool stick with your LS. Don't hate on it. That's why we have choices and it's personal preference. That's a beast of an engine bro. Mad props 💪

This is perfect i just got a ka s14 couple weeks ago

THIS IS INFO AT ITS FINEST!!!! LOVE IT GUYS KEEP UP THE WORK FOR US KA24'S

loved this! deff would like to see more of these types of videos. It helps people understand more about a particular engine instead of car forum hearsay, what works, what doesnt, what it's capable of and all that. 10/10

I learned so much about my engine mad respect to this guy I wish I was as knowledgeable as he is.

I had a buddy in highschool Sr swap his 240 He gave me the ka that was in the car and I swapped in in to a Chevy luv I still have that luv with that power plant and it's amazing

Great history lesson great appreciation about the KA24DE! Thanks.

Sounds like it's easier to do an SR20 swap, higher initial cost, but probably it'll end up being cheaper.

Very realistic i love how he lay everything in excel sheet then goes further how it lead him to the decision❤

I had a Ka24E-T that was way overbuilt for my power level. loved it.

The only reason I built my KA is because you still have to buy the same parts when doing an SR swap but you have to buy the SR. The KA is included and gives me an extra $2500+ for build parts. Still going since 2009 with no regrets.

No clips of him rippin this thing????. Love these videos about the technical advances and pros v. Cons of popular engines, very informative.

I'm 17 and I was recently handed down a 240sx with a s14 KA24 swap. I'm thankful I have uncles and friends who own a 240sx. I dont have to worry about where I need to get my information. To all new 240sx owners, good luck!

These engines came in Nissan small pickups in the Middle East, and they are quite good and very popular because of the reliability. we had the pickup since 2003 and now it has 416k miles without a single issue, when i went to Thailand in 2011 i saw so many after-market parts for KA24DE since it is widely used, maybe you should look into Thailand market since they have been modding this engine for a long time

No wonder why forsberg retain the KA-T(Matt powers Pro Am power plant) on his “missile car”.

This is sick…keeping my ka24 in my hatch and all this information is super useful thanks bro🔥

Cited this in my essay about KA vs SR. Thanks guys

I finally made the time to assemble a megasquirt DIYPNP for my D21. Looking forward to putting some boost to my ka24e.

Really appreciate the KA history lesson to get into the topic. Props, fellas.

JGS log, T3/T04E 50 trim .63 ar, XSPower IC setup, Z32 maf - draw through and on Enthalpy tune (when Scott was the owner). This was 2007.....

Such an insightful video, gotta love the Zenki

Here’s something I think Aron would like the idea of, Honda offers a drop in crate civic type r motor at a reasonable price. It’s $6700 for a complete engine with the turbo and $9000 for the complete engine with a wire-ring harness and ecu. For an engine that stock makes 300hp and can easily make 350 with just a tune it might make sense for a simple seat time car instead of adding a turbo to a 10-20 year old k20 /k24

Ive got a KA24DE in my 03 Frontier, 5 speed. Pretty good for a 4cyl, always wanted to turbo it!

I've been in the KA-T world for 12+ years. Stepped away for the past 5 but now just getting back into one, its the one I helped my dad build while I still had mine. It is a GT2871R/550/N62 car. Part of the reason I got rid of my last car was because it was too racecar. I'm going to keep this one a fun Sunday driver, and couldn't agree more that they're fun around that 300hp range. A lot of good info in this video!

4 years since this video was made, but it was still an interesting watch and a lot of what Spencer said is still true today. If anything prices have gotten significantly crazier since then... I wish I could pick his brain and get a blueprint on the perfect 1.5 level motor that he mentions near the end of the video. I currently have an S13 with a stock KA, and I'd like to get the car into the 250-300 HP range, but do I go for that 1.5 level upgrade path, or do I swap to something like a K24? SRs and other traditional swaps have gotten really expensive, and while I could technically afford to put in one of the more traditional swaps, I'm not sure if I want to sink that much money into this car which means my choices are limited. I'm nearly done with the bodywork so I won't be able to keep putting the decision off forever unless I wanna stay stock.

I have loved KA's for a long time and turbod one back in 2012 which is amazingly still running today. Dyno'd at 550whp but I also build the block and heads so not really a budget build. Have always stood behind these engines and for my abusive driving and carelessness with my own cars, they have stood up to the beating amazingly well. Love this video, love the car and the build. I love that hat too no lie. Where can I buy one? xD Awesome work!

quick 5- 10 sec clip of this thing sliding at the end be the cherry on top... you went on about the sound... would've loved to hear it...sick build!!!

Just found this channel..You look like a mix of Scott Manley ( Science youtuber) and Matt Damon...Dope video, new sub here

He's right about the longer stroke... My KA-T seems to never hit redline because it runs out of steam after 5500rpm. I think redline is 7.2k? Even with my gt2871r I don't really need to hit redline unless I'm drag racing the straight before initiating. All my power band is 2.8k - 5.5k

You guys have sold me. Gonna turbo the KA

where can we get the that coil harness set up ,, awesome video i can't believe i watch the entire video 😅😃😃😃😃👍👍👍👍

I have a 97 Altima with the ka24dea in it and basically looking for like a stage one turbo setup to get about 210hp and stay reliable for daily driving.

so much good info in this video. thank you so much for putting this up. I've been running around in circles trying to figure out what to do with my 240. I'm pretty new to all of this.

400whp ka-t with a cd009 must be a blast to drive .... i built one 5y ago but was on a stock trans and owner went through 4 tof them in one summer hahahahah

Thanks for sharing. I have been considering K24 swap. But if it ain't broke don't fix it.

Extremely Interesting and relevant thanks Aaron!!

Awesome to know a K tuned throttle body as a option. I've had a few leaky ka TBs and been using a sr TB for a while. Going over PCV system/catch can setup was helpful too, I've seen it routed a few different ways. Good info boys! KA FTW!

I love the KA building one now for an s13

I ran a fbo ka for about 10yrs using 245 tires. Super fun setup. Now im 1jz 🤙🏼

Quite informative. KAs don't get much love, but it's amazing how some people and smaller companies are doing aftermarket parts for these engines. Something that should've been mentioned is the durability and stresses the factory parts can handle before they fail. It's been suggested in Facebook pages that the stock rods can handle plenty of power before failing (stock pistons would fail first). How much RPM the stock crankshaft can handle before secondary harmonics start to become a problem. I was surprised the stock oiling system is that good, with no need of an SR style aftermarket oil pan. No mention of windage trays or oil scrapers, though. I want to make a KA-DET with the Tomei turbo kit. I'd love to get my hands on a Nissan Motorsports side draft intake manifold for turbo ITB setup, but it's most likely discontinued and a rare part to find. Since it will be for a street car, it will see an occasional drag/circuit run or two. Would love to get more into this platform in order to make safe reliable power without going overboard, using OEM and aftermarket parts. If anyone can suggest me where to get the help for that, it would be much appreciated. Thanks for proving that the KA isn't "just a truck engine". Its lineage can be traced back to the L engines, and that particular engine architecture was inspired by a Mercedes-Benz inline engine. So we can say the KA has some pedigree in it's design.

Shout out to the ka-t boys

“I’m here to interview this guy” *cuts him off constantly and answers his own questions*

great video aaron… really loved this!

Back in the day, you get an s13 redtop SR for the price of turbo kit for a KA. Lots of people thought the KA was an ugly engine. Like mentioned in this video, aftermarket was none existent for this platform. Fast forward to now a days, 4K + for an SR. You can build a very strong KA short block for that price.

Thank you for this video! I've been wanting to restore my 1986 Nissan Datsun D21 pickup for years now. It has the z24 engine in it, and I've been debating whether to do a KA24 swap, or an LS swap. This video made up my mind! I'm aiming for the 250-300HP range, and when you mentioned that I can get that power level, on stock internals, running pump gas, you had me sold!!

dont forget ka24det also can get 1100 cc stock inside feed injectors from a company called " five o "

best thing ive ever heard, KAs arent bad just poor owners

I have love for the KA24DE because they’re slow but torquey like the Toyota 3S-GE and 5S-FE. My friends and I were rockin these engines in the 90’s before we could afford 3S-GTE’s and SR20DET’s. Good times and fun races.

I appreciate this video

um...I have a few of these. and sr20s. KA's are super fun. None of these things have been a problem for me with my timing component upgrades. You can always make a stronger engine if you are a machinist.

Will this fit in my z31? I'm wanting to get rid of the ls and put one of these in there with a turbo even if it makes less power boost is what I want in my life

What transmission is behind it? Stock ka 5speed? Also what diff

36 of these viewers own SR engines

Sick! I'm picking up a ka t s14 this weekend!

Aaron: "He's not getting a better sounding engine like a L.... like a JZ!" OMG I laughed so hard haha!

Ive been running dual cam KAs since 2008-9ish. Only had oem headgasket failure and one spun rod bearing. I had a single cam- my first 240 ever, back in 2006, the timing chain guide was so worn that the chain wore a whole in the water pump, and flooded the oil pan with coolant and locked the motor up. Didnt know what had happened, 16 year old at that time. But yea, Idk what power I have but its plenty to drift and super reliable. Dual Cam with light weight pullys, light weight fly wheel. I only run one belt, No power steering. Used turbo off a duramax? lol ebay manifold and fmi. oem everything, i use a FMU and with oem fuel regulator. No Tune. Maybe some day I can afford some kind of tune, and dyno. Im at 7 psi of boost. In order to run more, need a tune, injectors, pump.

Why do we have MAF in the first place when a MAP does the same thing but doesn't break or burn out? Seriously I want to start a conversation about this

Aaron thank you for this quality video!

My friend has a built twin cam KA that was fully built in 2010 w/a ford Mustang throttle body and he had been killing sr20det ever since I told him it's like a chevy guy pulling out a 454 cid and swapping in a 305 cid he is very glad he listened the car is still running today

So energetic lmao, he wasn't ready

Thanks for all the information. I'm building one for my 1991 240sx. The majority of my 240s have been SRs or RBs. This will be my first KA24DE-T, wish me luck. 🤪😂

I’m building a KA with eagle h beam connecting rods Weisco 9:5:1 pistons Clevit bearings Cometic head gasket Bc valves and springs But I’m looking for a good engine management can you give me some pointers

I own a stock 96 ka 240sx with 100k which still runs great but need a new shell before I can start my build

You say better, but all I hear is richer....parts availability is where its at.

Na ka sub 200hp is doable and sound great if you dont have an annoying exhaust. I love them, but more for spirited driving. My favorite honda build was a nonvtec LS that put down 176whp. We had it in an 89 4 door civic. Full suspension with azenis at 65psi. That car was scarey fun.

Spencer is the man !!!

Boom, would you say that's accurate? BAM!!

Been thinking on doing an KA swap on a Porsche 944 or 924S. Reliable power for sure

As much as a turbo build would be cool, i just got done with my Dual sidedrafts on my Single cam and i love it, tuning is another subject but the sound and simplicity of it is amazing.. Been driving this truck for 15 years and as many problems ive had with mafs, ecus, and harness issues, I think having a 2 wire ignition and some beautiful webers on the side is well worth it

I was hoping there would be comparisons between the recent to market Tomei turbo set up to the ISR and the Full Race mani

Several years back there was a company making a supercharger kit for the ka that used a S/c off of the nissan pathfinder. Any opinions on that? Its not very common but for a person like me who enjoys the feel of linear torque from the na stand point, the S/c kit would be the way to go IF it is/was obtainable.

I put 18psi on my ka24e single cam on e85 making 300hp stock internals

I can tell you alot about the Z24 engine. I drove one 300k miles. Very good engine aside from the smog crap and carb.

I wish there was more info on CA's. Thank you for this video.

Super dope video give me motivation on my s14 build

Excellent video

Did I miss it or did he mention any drivetrain stuff? I assume he's using a white bunny size clutch setup and is he still stock trans and diff?

KA ALL DAY

KA gang!!! I myself have blew up a few KA’s after turbo’ing them, but that was due to lack of proper ECU management (Stock ECU w/ SAFC. T25 turbo, stock internals). I was actually debating on swapping over to SR but decided to stick with the KA, but with proper management this time. I’ve went with Nismotronic, and currently in the process of putting in another KA. This time it’s a freshly built motor with forged rods & pistons and BC valvetrain with ZERO miles on it. A friend was building it to throw in his s14 but he found an SR for a good deal before he could even run the car so he sold it to me for cheap. Subscribe to my channel for updates!!! Very good informational video though guys, respect!

Shouts out to Martin!

What I didn't hear either of you say is that everything you do to make NA power is going to increase your gains per PSI when you go to forced induction.

i would REALLY LIKE TO KNOW how I could go about a honda k24/20 into the hardbody with my trans

Question: will a KA-24 be good for an reliable everyday day? . I want to put it in a 94 hardbody...nothing fancy just to get me around but a little more power than what it has now... your feedback would be much appreciated

Subscribed bro!

A level Design & Technology exam tomorrow hopefully this gives me some cool ideas :)

Thanks for the very informative and great video! I'm really interested in his choice on keeping the OEM intake manifold. He mentioned there are no options that have been proven to make the same power curve as the OEM, especially in the low end range. I've always considered the Xcessive Engineering manifold to be a great option; but I'm really surprised to hear it really is not an improvement? Would love to hear more of yours or Spencer's opinion on this!
