Welcome to another episode of "What's So Special About..." Today we're looking at Honda's famous K-series. Honda’s contribution to motorsport and the JDM performance scene is unquestionable and today we’re going to take a closer look at what is arguably the most popular “modified” Honda engine - the K-series. If you've ever wondered why and how a "K-swap" became such a phenomenon - Scott is here to give you all the answers! This is another rather long video, so if you want to jump to the section that you're most interested in use the shortcuts below: Honda's History: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html Engine Overview: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html Tuning Options: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html Things To Look Out For: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html Specs and Features: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html Engine Teardown: th-cam.com/video/nJ3tlKsPfLg/w-d-xo.html
Whilst its a bit more obscure... or not obscure but less common to tune... could you look at the k20A3. Economy vtec but i wonder if it would take well to a remap? Also interested to see how it runs as a 12 valve.
Two of many reasons why I love Honda’s so much: 1 I’m a full time mechanic for over 20 years and work on everything from golf carts to fire engines and 2: I purchased my 2002 Acura RSX Type S brand new and still driving it daily now with 455,000 miles, original water pump, oil pump, good compression and no engine lights, synthetic oil changes every 3k and valve only two adjustments needed, yet it still runs like a champ and no I’ve never ever babied it when driving it but strict with maintaining it, Honda is the power of dreams with no doubt
I own a 04 ep3 with rsx s type s motor 6 speed I boosted mine with hondata And I never put in a tune and she ran fine to about 10 t0 12 psi. Afrs look decent. It's hard to blow up stock setups. She loves boost.
Honda has always been about engineering details in their engines. I don't get why they receive so much hate. They are great. Ever since the S600s with the roller bearing cranks.
@@poptartmcjelly7054 you're definitely right about that one and its usually done by enthusiasts that either can't afford the correct mods or they're that certain crowd of guys we all hear about.
Sadly idiot civic drivers give them a bad name. Now I have a civic have the 1.4 D14 that's the one that gives hondas a bad rep. Because people stick a stupid intake on it and a fat exhaust but the engine (from stock) won't benefit from those mods. So it sounds crap performs crap but the drivers think it's fast
"Without racing, there is no Honda." -Soichiro Honda. Edit: this show is amazing! I think I just got a college degree in Honda K- series engines. Their engineering is mind blowing. Thank you so much! Edit2: pull apart a Subaru boxer engine next!
I have Honda d16 turbo. Cheap to upgrade to 500 hp and very fast and fun. Sorry Honda haters us Honda drivers will wave on the way past if we're not on boost 👍
I've always been diehard a B series guy but the K is a pretty robust piece of engineering. Still prefer the B due to simplicity but the K literally stands for King
Likewise; built (all motor) B18C5 here, and I know I'd benefit in numbers from a K. However, each time I hear the sound of my setup and feel the need to rev it out, I think "Nah lol." Plus simplicity. To anyone else I'd recommend a K, however I'll be a hypocrite and stick with a B until there aren't ICEs on the road any longer.
Careful with that understeer bud. The LSD is great if you have a good suspension setup to back it up. I crashed for pushing too hard and under steering into a ditch 😂
You forgot to mention that the massive oil pump assembly houses the counter-rotating balancing shafts that reduce the second-order vibrations of in-line 4-bangers. Truly an ingenious design to keep the engine block simple and robust. Simply a beautiful bulletproof engine!
Makes me feel even better about my Accord Touring 2.0. Read last week from JD Powers that Honda engines in general have less than half the failure rate than their next closest rival. Pretty sick.
I think the haters are just annoyed that a manufacturer managed to produce an engine that combines everything - huge tuning potential, simple construction, doesn't leak, and it's unkillable. I bought an 05 Accord Euro Luxury Sport about 10 months ago. The thing is 15 yrs old, but still feels like a new car. No rattles, no squeaks. 147kW, one of the best 6spd manual boxes you can get, and double wishbone suspension on all four corners. I've paid $5k for a car that beats so many other cars hands down. This is one car that I can't see myself ever selling.
Donut Media also has a great video of Honda. Donut Media maked their video very playful but 0 hate, which is amazing. Have driven 3 civics in my life, and never regret having em. Now i have a CRZ, i will always buy a Honda, reliable, fun and great to drive. I respect everyone's choice, but yeah, i also had ALOT of haters on me. Oh well, they are just jelous i drive reliable ;)
As stock, it's 295 cfm per port on the original ones (2.0L RBC head) and 300 cfm on the revised ones (2.0L RSP head). :D Around 280-285 cfm on the Accord Euro / TSX cylinder head intake ports IIRC.
@@dadigitechman Not in particularly large numbers, and a K-swapped plane is going to be considered an experimental. There are also LS swapped and Yamaha swapped planes in a similar situation. All fantastic, but niche and legally restricted. The most successful auto engine for airplanes is a Mercedes V6 diesel, which is offered as stock in Diamond brand airplanes. There's nothing wrong with car engines, except that the aviation world is RIDICULOUSLY conservative and it costs unholy amounts of money to certify an engine for a tiny market. Even a small company like Mazda moves more engines in a month than the entire general aviation industry does in a year. It's just not worth any company's time. Diamond went through certification on the Mercedes engine (originally rebranded as Thielert and now Austro) because they wanted their million-dollar airplanes to be ridiculously efficient. They achieved that with the Mercedes diesel, but it came very close to sending Diamond to the shadow realm. Most of the time it makes more sense to just use the old 1930s-tech airplane engines that got certified back when aviators weren't all golf-playing lawyers. They work, they're light, and if Ferrari prices for VW Bug tech bother you, then maybe you're too much of a poor-people for aviation. IMO we'd all be better off throwing the lawyers out of helicopters and putting K24s into the planes.
I didn't even know this "What's so special about" series was a thing, but I absolutely love it. Thanks for both the history lesson and the detailed teardown!
This guy is really knowledgeable, he even knows the history of the Honda engine and presentation is flawless .. I'd say this is one the best and most interesting video on Honda's engine. Thanks so much for this video, thumbs up!
Thanks Scot brilliant explanation of a K series Honda engine. See so many of them on You tube video great to see a full pull down. Haltech Let Scotty done a K Series build
Now I know why my well maintained K-24 equipped CR-V with 160,000 miles feels like it is at the break-in point. The engine burns no oil, has plenty of power, starts instantly, and is quiet and smooth.
Dear Honda: Find some bloody excuse to make an i6 3 to 3.2L version of this engine. And keep producing it as crate engines once everything goes electric. That would, in time, be remembered even more fondly than the 2JZ. Dear Haltech: Just keep 'em coming! I would however like to request that you equip Scotty with a swim suit assistant to hand him tools, dab oil smudges off his face and other essential tasks. It would certainly improve his presenting efficiency with many percent!
@@rhangman8284 and how many would buy that, and you can't just make it longer, you need a new crank shaft, and due to it being longer it will flex more so you need more main bearings. That's why i6s has like 7 or 8 mains but i4s has like 4 or 5.
Thank you! I have a 2009 Honda CR-V with a K24Z1 engine and never understood exactly what the "Intelligent-Variable Valve Timing and Lift Electronic Control i-VTEC" was or what it did. Your showing the separate rocker-arm components at 15:45 made it clear. That is a clever design. I keep up with routine maintenance on my CR-V and it has always paid me back with absolute reliability. Honda builds excellent cars. :)
I remember building some B16's back in the day and some of the work that had to be done and aftermarket parts added to make them hold lots of power. It makes me happy to see that Honda engineered some of those improvements right into the K series.
You don't know how many TH-cam videos I went through before I found this one. Awesome video fully explains my awesome iVtec engine. Thank you so very much! Brilliant!
The best engine engineering I've seen is the innards of a 70's 2 valve Jawa Eso speedway bike. The finish everywhere is immaculate. Every thing is polished and matched.
Best strip-down video, I’ve seen yet. I love Honda’s. I run an FK8 and daily a Honda FIT RS. Very clean power and reliable. What impressed me about your video is that you took a little bit longer, which is risky on TH-cam, to explain things. You never lost me! I’m biased though and with great reason. I’ll share your video in my Type R playlist and some of my Honda groups that I frequent with tales of street racing and mods.
Thanks for the heart mark and thumbs. If you are interested in seeing my FK8 build, have a look at my YT channel SpinRush_C1. I have made some videos on my HKS Technical Factory build.
It's like the polar opposite of watching a EA888 being torn down. Elegant engineering (Honda) vs how the hell did they make that so overcomplicated (VW)! :)
Just got into the K series engine since i got a civi si . Man , blow away by the way this engine looks inside. Magnificent, massive brace system top and bottom.
It’s neat to note that the first person to propose using an engine brace in a Honda was the CEO and mastermind of Spoon Racing. He uses one on the famous 11K RPM B16.
i know all about this stuff already but still watched it. i can still remember my tuner/mechanic was hella geeking out the first time we disassemble a K motor at the shop shouting that this is the shit right here! he is still inlove with the engine. lol. that was 15 or more years ago. man! time flies!
As a mechanic of nearly 25 years who has worked for GM, Ford, Toyota, and now Honda for the last 15 years, I have long argued that the Honda 2.4L I4 (especially the K24) is the best made I4 in the history of the automobile world. If maintained this motor will never brake down. I have seen Accord's come in with this motor having 300 and even 400,000 miles and tell me they've only ever changed the oil and done regular maintenance. It is an absolute shame Honda abandoned this power train and went with the horrific 1.5L turbo. In my 15 years at Honda I have never seen so many issues with a motor and they're not getting better. When you see more new cars with the 1.5L than old cars then you know you have made a dud. I cannot recommend the 1.5L to anyone. I will recommend the 2.0L turbo though. That motor is much more robust and does not have the same issues. With that said, you cannot beat the 2.4L nor the 3.5L V6. They are simply the best.
Great engine design and way ahead of it's time and today. The ribbed block also contributed to rigidity. Oil jets were also introduced to lubricate and cool the pistons. Coolant jacket also kept the cylinders nice and cool. The VTEC VTC system had four different valve timing modes for engine performance: idle, low rpm economy, low rpm torque, and VTEC high rpm torque. The FD2 Type R K20A was extraordinary for a factory performance engine with racing upgrades on almost every component: pistons, rods, porting of manifold + ports, flywheel, oil pump, exhaust header, etc.
Do a K20A from euro R and type R teardowns :) you'll see extra surprises again. And by the way the K24A oil pump is a balancing shaft as well. All built in.
this guy knows what he's talking about. i watched this guy grow since the beginning. he's appeared on mcm and is the master of haltech systems. i watched his career grow on youtube. this guy is a legend
GFs 04 TSX had 390,000KM when it spun a rod because of oil starvation. Otherwise it was still running strong. Just got her a 11’ Si and she LOVES IT! AMazing little car!
That's the oil pump with balancer which was used on the K24 & certain derivatives of the K20 (that's why it is such a beast of an assembly). Most performance builds delete the balancer assembly. Some use a modified version of the pump used on the F20 engine if it is a super high rev build. They are a nice bit of kit, amazing they made money selling them!
Well done video... One omission: You neglected to mention that the neatly designed oil pump assembly also incorporates the balance shafts, using the same drive, all in one compact module.
I noticed that. Another thing of note is the integrated steel / iron supports located in the underside of each of the main bearing caps. They can be identified by the darker colour than the rest of the bearing cap assembly at 27:45
Just had to jump in here to make my first comment to thank you for the Honda love. It's been evident to me in the past decade+ that there has been a lot of pop shots directed at Hondas by the internet forum community (including that other TH-cam channel that mod cars mightily) that Honda sucks this, Honda sucks that, and I see it actually deceiving or misleading the younger generation that are newly getting into the car enthusiast scene. With videos like this and your passion showing in presenting it, I hope the younger crowd get a little more educated and are properly guided in the right directions. Thank you.
I build these engines for all my buddies doing swaps- 150$ at a junk yard and some good TLC with a good balance, lightweight forged Rods and OEM type R pistons-- I love them cause they’re over engineered but super easy to work on and build-- building a Frankenstein swap Rn for my rsx to push 350 whp NA
Thanks Scot for an amazing video. It’s actually really nice to see you get so excited over what most see as just another humble Honda engine. There is just something about the K series for me that no other engine can replace. It’s like a bit of an underdog hero. I cannot actually see a time when I won’t own n EP3 or at least something with a K20 in it. Oh and I love the idea of you doing a turbo K20 project. Maybe you could get the mighty car mods guys in on it as well.
Wow. Best teardown ever. So special that K series, nothing wails like it. I want to mount it on a band and wear it on my wrist. S. Honda is obviously enjoying a well-deserved, continuously variable, oil squirted perch in heaven. Thank you Mr. Honda. But lads, have to say, great vid. Special effort. Most appreciated. Victoria, BC, Canada. (Sooooo Honda B-series? Please? Pleeeaaase. Ugh, I didn't want to have to beg.)
Awesome video as always, such amazing engines when you consider where you find them. I'd also like to add, that we are still waiting for the SR20DET techically speaking video.
#Haltech changing the game since..... well forever actually...... You fellas are on another level!! Its so good to see your products world wide in so many applications!!!
Yea he should have mentioned that’s the K24 pump and it’s mainly for comfort and smooth operation while the s type pump is better for performance and higher RPMs.
Honda K series in my S1 Lotus Exige. 300 bhp supercharged. Revs to 8,000 - pulls in 6th from 900 rpm. Ultra reliable and will last for years! (Has lasted for years burns no oil)
Took me long enough to come checkout your channel. Sorry for that my dude. I have been watching MCM for years. I knew you had started a channel, and I just forgot about it till today. I have a lot of catching up to do, I see!!! I can't wait to dive down in the rabbit hole!!!!
very nice! was hooked from start to finish especially when the engine was torn apart and the bits and pieces were explained! kind of nice to hear one for 4A-GE (black top maybe?) thanks!
Excellent video, i am a proud k24a3 owner,reflashed and 421 headered by littlebo, amazing engine, outruns most of the 2 3 liter engines found on similar saloons
In Canada we got an Acura CSX that was a compact 4 door with either k 155hp with paddle shifter automatic or a 200hp type a version. My CSX has 320 000km, check engine light turned on for miss fire. Changed the spark plugs and the code cleared itself. Best 4 bangers ever. You forgot to mention the all mighty k2.3 turbo RDX monster in an suv.
@@UsmanKhan-fp5uu not enough to matter, especially on the K24A2 out of the 06-08 TSX, it has increased crankshaft balance weight. Though personally when I get around to my swap I won't do the countershaft delete without also installing a viscous harmonic pulley
I wonder if the overly sturdy construction of especially the bottom end is the result of Honda coming from sports bikes and a long history of formula sport, where the engine is used as a stressed member (gearbox and rear end hanging of it).
Big thanks for the 'Giant man with the giant heart', for making this video. As a K20Z4 owner, this makes me adamant that these are the best pedestrian car engines.
You know, I've always hated Honda, like with a blind passion then I realized how silly that is, we are all Car enthusiasts and have similar interests. I've made more friends due to cars than anything else, even people who I've never met in person. It doesn't matter what you drive (sort of) , what matters most is: What Drives You !
I was like you. Then, when i bought by 1st brand new car i checked just abour every car in my budget and a Fit ticked all the boxes... I was "well let's see.." and now i have a 2012 Si. Nervous, relatively easy on gas and just plain bulletproof! ...but i don't beat on my transmission..
Love your video it was very knowledgeable and helpful I hope to see more I would love to see Nissans twin cam 24 valve engine if you can do that that would be nice
First F1 win was in 1965, by American Richie Ginther. (I'm guessing the teleprompter had an error on it) Great Video! Love these the informative videos :)
I'd love to see some explanations of the inner workings of an EZ30R by Subaru, the dark horse of subaru. They have some great tech inside them, and some good potential being shown as a few more people are starting to turbocharge stock motors (like myself), as well as build some pretty strong ones with upgraded internals!
Thanks for showing us this K4 engine. I have a 2013 Honda Fit Sport that I really enjoy driving. I only wish I had a 5-speed. The engine is amazing. Honda engineering is amazing.

@@haltech Hell yeah! Neck beard and swimsuit is so going to be the new black!
His face :0 when he was looking at the crankshaft like his most loved child! love it
Damn, there really is a ton of genius wrapped into those. Makes me want to play with one.
Thank you! I have a 2009 Honda CR-V with a K24Z1 engine and never understood exactly what the "Intelligent-Variable Valve Timing and Lift Electronic Control i-VTEC" was or what it did. Your showing the separate rocker-arm components at 15:45 made it clear. That is a clever design. I keep up with routine maintenance on my CR-V and it has always paid me back with absolute reliability. Honda builds excellent cars. :)
I remember building some B16's back in the day and some of the work that had to be done and aftermarket parts added to make them hold lots of power. It makes me happy to see that Honda engineered some of those improvements right into the K series.
Really respecting these engines more and more.
You don't know how many TH-cam videos I went through before I found this one. Awesome video fully explains my awesome iVtec engine. Thank you so very much! Brilliant!
I love my 02 RSX Type-S. Honda for life!
Yes sir.
Yes sir.
The best engine engineering I've seen is the innards of a 70's 2 valve Jawa Eso speedway bike. The finish everywhere is immaculate. Every thing is polished and matched.
Best strip-down video, I’ve seen yet. I love Honda’s. I run an FK8 and daily a Honda FIT RS. Very clean power and reliable. What impressed me about your video is that you took a little bit longer, which is risky on TH-cam, to explain things. You never lost me! I’m biased though and with great reason. I’ll share your video in my Type R playlist and some of my Honda groups that I frequent with tales of street racing and mods.
Thanks for the heart mark and thumbs. If you are interested in seeing my FK8 build, have a look at my YT channel SpinRush_C1. I have made some videos on my HKS Technical Factory build.
It's the british accent that kept you listening.. lol
Not only did this video school me on honda, but I learned so much about engine layout. Thank you
Staring at a Honda engine's bare bottom end is actually quite the experience. Beautiful craftsmanship and design.
It's like the polar opposite of watching a EA888 being torn down. Elegant engineering (Honda) vs how the hell did they make that so overcomplicated (VW)! :)
Tuning Fork!Never thought you were going to love a Honda motor so much!!!
I intend to put a k20-a2 in my old civic. This has made me want to do it even more. Sure hondas get a bad rep but when done right they are amazing.
A k swap in any light weight chassis is an instant win, ef, crx, eg, ek, mx5, lotus Elise.
Honda’s get a bad rep from people that don’t understand engines.
I wish mine had that. I got stuck with the K20A3
This video is so insightful! Knowing more about my engine on my stock tsx makes me appreciate it more !
3 or 4 times you were so enamored with the designs I thought you might give it a kiss lol
😚
Just got into the K series engine since i got a civi si . Man , blow away by the way this engine looks inside. Magnificent, massive brace system top and bottom.
It’s neat to note that the first person to propose using an engine brace in a Honda was the CEO and mastermind of Spoon Racing. He uses one on the famous 11K RPM B16.
Every time you said K-series, my phone wanted you to finish asking a question. Great video too!
i know all about this stuff already but still watched it. i can still remember my tuner/mechanic was hella geeking out the first time we disassemble a K motor at the shop shouting that this is the shit right here! he is still inlove with the engine. lol. that was 15 or more years ago. man! time flies!
I am 5,5 years now with my 2001 Stream k20a engine. Totally in love with it...
As a mechanic of nearly 25 years who has worked for GM, Ford, Toyota, and now Honda for the last 15 years, I have long argued that the Honda 2.4L I4 (especially the K24) is the best made I4 in the history of the automobile world.
If maintained this motor will never brake down. I have seen Accord's come in with this motor having 300 and even 400,000 miles and tell me they've only ever changed the oil and done regular maintenance.
It is an absolute shame Honda abandoned this power train and went with the horrific 1.5L turbo. In my 15 years at Honda I have never seen so many issues with a motor and they're not getting better. When you see more new cars with the 1.5L than old cars then you know you have made a dud.
I cannot recommend the 1.5L to anyone. I will recommend the 2.0L turbo though. That motor is much more robust and does not have the same issues.
With that said, you cannot beat the 2.4L nor the 3.5L V6. They are simply the best.
I'm getting a 23 odyssey and can't wait to upgrade to v6 from my 18 crv (no issues with the 1.5L aside from a little oil dilution)
Yeah snake. Looking at civic si. Are the o6 to 12 good. Love manual transmissions. Need some feedback. Thanks.
@@jeffcollier8780 06-11 have the best k20 we got in America, same with the RSX type s but the civic Si has a LSD
Great to hear just brought 2011 accord with 109thousand kms full service history, 1 owner, ask me in 10 years hope your right.
@@petergiourelas3753 If the maintenance was done and you continue that process it will last forever. Congrats!
Great engine design and way ahead of it's time and today. The ribbed block also contributed to rigidity. Oil jets were also introduced to lubricate and cool the pistons. Coolant jacket also kept the cylinders nice and cool. The VTEC VTC system had four different valve timing modes for engine performance: idle, low rpm economy, low rpm torque, and VTEC high rpm torque. The FD2 Type R K20A was extraordinary for a factory performance engine with racing upgrades on almost every component: pistons, rods, porting of manifold + ports, flywheel, oil pump, exhaust header, etc.
I can see why Honda is so great because of they keep on putting R&D into their products. Great job and explaining Haltech. Thank you.
Noce job Scott explaining everything.
I have enjoyed listening to your knowledge on MCM, and now Haltech channel.
Give this dude a raise!!
Do a K20A from euro R and type R teardowns :) you'll see extra surprises again. And by the way the K24A oil pump is a balancing shaft as well. All built in.
this guy knows what he's talking about. i watched this guy grow since the beginning. he's appeared on mcm and is the master of haltech systems. i watched his career grow on youtube. this guy is a legend
Love my 05' TSX. Great engine, not fast by any means, but very smooth, predictable and reliable
My 06 tsx is quick but not fast lol.
Yep 08 typeS here. Unbelievably smooth engine.
GFs 04 TSX had 390,000KM when it spun a rod because of oil starvation. Otherwise it was still running strong. Just got her a 11’ Si and she LOVES IT! AMazing little car!
I'm glad I have a k series after watching this👍🏻
That's the oil pump with balancer which was used on the K24 & certain derivatives of the K20 (that's why it is such a beast of an assembly). Most performance builds delete the balancer assembly. Some use a modified version of the pump used on the F20 engine if it is a super high rev build. They are a nice bit of kit, amazing they made money selling them!
This is the best tear down video I’ve ever seen. You’ve explained everything as easily digestible as possible. Very good work!
best video on K engines I've found. thank you!
One of my favourite car youtube hosts/personalities. Takes these videos from a 9/10 to a 10/10
Every time he said ‘K series’, Siri came up
That's just Siri being jealous, don't worry. ;)
Best HONDA Engine explanation simplified. Kudos. Do all the other series!
Well done video... One omission: You neglected to mention that the neatly designed oil pump assembly also incorporates the balance shafts, using the same drive, all in one compact module.
I noticed that. Another thing of note is the integrated steel / iron supports located in the underside of each of the main bearing caps. They can be identified by the darker colour than the rest of the bearing cap assembly at 27:45
I love this type of video. Doing a deep dive on stuff like this is so educational and I love it.
Just had to jump in here to make my first comment to thank you for the Honda love. It's been evident to me in the past decade+ that there has been a lot of pop shots directed at Hondas by the internet forum community (including that other TH-cam channel that mod cars mightily) that Honda sucks this, Honda sucks that, and I see it actually deceiving or misleading the younger generation that are newly getting into the car enthusiast scene. With videos like this and your passion showing in presenting it, I hope the younger crowd get a little more educated and are properly guided in the right directions. Thank you.
Success brings hate.
this video made me fall in love the K series and convinced me to swap it into my e30
Hoonigan plug there... This is a great motor! Haltech ecu all the way for engine management. Keep kickin as guys!
I build these engines for all my buddies doing swaps- 150$ at a junk yard and some good TLC with a good balance, lightweight forged Rods and OEM type R pistons-- I love them cause they’re over engineered but super easy to work on and build-- building a Frankenstein swap Rn for my rsx to push 350 whp NA
Thanks Scot for an amazing video. It’s actually really nice to see you get so excited over what most see as just another humble Honda engine. There is just something about the K series for me that no other engine can replace. It’s like a bit of an underdog hero. I cannot actually see a time when I won’t own n EP3 or at least something with a K20 in it.
Oh and I love the idea of you doing a turbo K20 project. Maybe you could get the mighty car mods guys in on it as well.
Wow. Best teardown ever. So special that K series, nothing wails like it. I want to mount it on a band and wear it on my wrist. S. Honda is obviously enjoying a well-deserved, continuously variable, oil squirted perch in heaven. Thank you Mr. Honda. But lads, have to say, great vid. Special effort. Most appreciated. Victoria, BC, Canada. (Sooooo Honda B-series? Please? Pleeeaaase. Ugh, I didn't want to have to beg.)
Awesome video as always, such amazing engines when you consider where you find them. I'd also like to add, that we are still waiting for the SR20DET techically speaking video.
#Haltech changing the game since..... well forever actually...... You fellas are on another level!! Its so good to see your products world wide in so many applications!!!
This video made me a proud owner of my 06 TSX
Amazing explanation of i-VTEC!! Fantastic information all around!
Toyota 1fz-fe
Always wanted to see what power can be produced from the big lump of an engine, that spends its days moving masses of weight around 🤞
please keep the k content going, love to see what you can do with the right factory components. thats whats beautiful about it!
That is a balance shaft assembly. Oil pump is there too but most of that is the balance shaft assembly.
Yes. FasterProms with Brent on their smart car included swapping to a type S (I believe) oil pump to remove the balance shaft rotating weight.
Yea he should have mentioned that’s the K24 pump and it’s mainly for comfort and smooth operation while the s type pump is better for performance and higher RPMs.
@@Dmanpeterson He didn't mention the balance shafts but he did say repeatedly that it's a k24.
To be honest, it sounded like the fork didn't recognise the balance shaft assembly and just call the whole unit oil pump.
Dark Ra true. Good quick video regardless. Surprised that is had a build head and stock oil pump honestly.

Took me long enough to come checkout your channel. Sorry for that my dude. I have been watching MCM for years. I knew you had started a channel, and I just forgot about it till today. I have a lot of catching up to do, I see!!! I can't wait to dive down in the rabbit hole!!!!
very nice! was hooked from start to finish especially when the engine was torn apart and the bits and pieces were explained! kind of nice to hear one for 4A-GE (black top maybe?) thanks!
I’m thankful that I found this video. Absolutely amazing! Great job.
B230F! Volvo FTW! Hahaha love the videos, :)
Great video! Helping a friend with his 2007 Element and now have a better understanding of what’s going on inside! Thanks 👍🏻
The K201Z is my favorite engine. N54 is a close second.
Fantastic Scott! Now I know why everyone is raving about these engines! I would love to see you do a breakdown of the legendary 4age please 😃
All though I am Vipec guy,I love your videos!
Excellent video, i am a proud k24a3 owner,reflashed and 421 headered by littlebo, amazing engine, outruns most of the 2 3 liter engines found on similar saloons
You should definitely do a K-swap! Do it on some 90s Japanese nugget.
"Vtec mini with mighty car mods"
My 2006 Accord 2.4 kicks ass. I've put this motor to the test. Still runs like new.
K is King..greeting from Malaysia..✌
In Canada we got an Acura CSX that was a compact 4 door with either k 155hp with paddle shifter automatic or a 200hp type a version. My CSX has 320 000km, check engine light turned on for miss fire. Changed the spark plugs and the code cleared itself. Best 4 bangers ever. You forgot to mention the all mighty k2.3 turbo RDX monster in an suv.
How about the GM 3.8 litre series II V6, it's a great little engine. Thanks, Scott, love ya' on MCM!
Excellent engines as well!!
27:00 this is why the oil pump needs to be timed to the crankshaft, it's not only the oil pump but your two balance shafts are also in there
Unless you do the K20A2/K20A oil pump conversion eliminating the counter balance shafts and allowing it to rev out quite a bit further
@@ericmullen14 but wont there be more vibration if we just remove balance shafts from k24 pump ?
@@UsmanKhan-fp5uu not enough to matter, especially on the K24A2 out of the 06-08 TSX, it has increased crankshaft balance weight. Though personally when I get around to my swap I won't do the countershaft delete without also installing a viscous harmonic pulley
I wonder if the overly sturdy construction of especially the bottom end is the result of Honda coming from sports bikes and a long history of formula sport, where the engine is used as a stressed member (gearbox and rear end hanging of it).
Definitely. I know honda supplies K series engines for f3 americas
Big thanks for the 'Giant man with the giant heart', for making this video. As a K20Z4 owner, this makes me adamant that these are the best pedestrian car engines.
You know, I've always hated Honda, like with a blind passion then I realized how silly that is, we are all Car enthusiasts and have similar interests. I've made more friends due to cars than anything else, even people who I've never met in person.
It doesn't matter what you drive (sort of) , what matters most is:
What Drives You !
I like aggressively driving my Toyota Sienna 3.3L V6 VVT-i so yeah, it really doesn't matter what you drive.😂🍻
I was like you. Then, when i bought by 1st brand new car i checked just abour every car in my budget and a Fit ticked all the boxes... I was "well let's see.." and now i have a 2012 Si. Nervous, relatively easy on gas and just plain bulletproof! ...but i don't beat on my transmission..
I got one of these engine in my fn2 type R. Drive it every day and love it .
I can't wait to get my JDM EP3 with a K20a.
did you get it yet?
@@thegreatcactus4922 yeah dude I got it just over a month ago, such a rad little car
With ya there bro little go carts 😤😎
I like how detailed you are.
Love your video it was very knowledgeable and helpful I hope to see more I would love to see Nissans twin cam 24 valve engine if you can do that that would be nice
First F1 win was in 1965, by American Richie Ginther. (I'm guessing the teleprompter had an error on it)

Honda was around a few years before making piston rings for Toyota. I am no mechanic, but this was a pretty awesome video.
Got to do a 1KZ-TE. Loved that engine.
Had one in my LC colorado, great engine
@Newblood Yes mate. Came out in the 1999 SR5 Hilux. Owned one. And loved it.
I reckon the 2.7 l petrol motor turboed would be interesting to see how it goes. 🤔
Great video Scotty! I have a k20z1 in my 06 RSX type s. Not the fastest engine but definitely a tonne of fun to drive!
I'd love to see some explanations of the inner workings of an EZ30R by Subaru, the dark horse of subaru. They have some great tech inside them, and some good potential being shown as a few more people are starting to turbocharge stock motors (like myself), as well as build some pretty strong ones with upgraded internals!
Thanks for showing us this K4 engine. I have a 2013 Honda Fit Sport that I really enjoy driving. I only wish I had a 5-speed. The engine is amazing. Honda engineering is amazing.
