It's arguably the best 4 cylinder ever made. There are modern engines that make more power now, but a K series engine is simple, reliable and still has plenty aftermarket support.
I've been running a K20Z4 for over 10 years, putting out 250bhp for the last 6 years. Only had one issue, a dead coil pack. Other than that, just good maintenance. Great vid BTW, thanks.
@Revs k20z4 alaso here, i run it for over 10 year with 230hp but before 2 years i blows all 8 exhaust valves🤣 ok every day i had miss shifts becaus of extreamely hard driving. I replaced all 16 valves with jdm valve spring
I do miss these loud unapologetic 4-bangers. I feel that Honda reached the ultimate of NA engine building and sold it to the masses at affordable prices. They were so early in introducing the VTEC system and placed it in every possible engine they sell. This allow them to make a profit despite a more complex valve train. For us consumers, truly a gift! Compared that to other companies that make a 9000RPM engine; Honda is the cheapest and Arguably one of the best.
got my RSX at 160k km, now at 338k km with only timing chain tensionner (preventive). OG engine and transmission, and it's driven WOT a lot of time, fast cruising at 150 km/h at around 4200 rpm. Doesnt drink oil or nothing. Best engine ever.
the biggest seal of greatness for any engine is how many stock components you can keeping using even on high hp forced induction builds. honda has always been the best with this.
Yup, I believe the critical internals being designed with such huge safety margins is one of the main reasons why Honda has always had one of the lowest engine failure rates in the industry.
K20 and k24 have been Honda most Efficient in terms of reliability and power. You can modify it so easy and it will respond adequately. In addition to this, K series were made to be rev’d out to Redline and it will not hesitate in redline. To me the K will always be top tier, k series only
@@mann_idonotreadrepliesyou're thinking of subaru's ej engine, k's are damn near indestructible. I beat the piss outta my k20z3 revving 9k for 3 years and swapped it out, sold it and it's still running to this day.
Personally, I think it's one of the greatest 4-cylinder engines out there. Please VisioRacer, if you could do a similar video about the F4R engine (as the one you had in your Megane 3 RS), that would be awesome. Thanks, and cheers from Spain.
Great video. Modern gear heads must respect the racing heritage of Honda and that they’ll make a kick ass performance engine that doesn’t have to equate to major power but with that prolonged reliability.
I’m a honda tech and It amazes me that honda still uses the K,J, R, L series today. All 20+ year old engine platforms. Obviously not the same as their older siblings but very good updated platforms.
I will say, the modern variants of these older engines are heavily modified to the point it's hard to swap some parts between K20C, L15C and J30C with their family. Still, it's amazing that Honda can keep even these family names alive for so long
Because they’re great ! I need to see a new Acura Legend in the states. Imagine if base models had G series and the A Spec Type S whatever had the new 3.5
With the cost of new-engine development, Honda played it pretty smart. Make a couple winners, (B,K,J) and you can put them in just about anything for 20 years.
8:28, absolutely digging the editing. Letting the audio from that acceleration clip slowly fade into the background feels professional. Good stuff brother, keep it up 💪
I'm a motorcyclist who dislikes car engines because they don't rev high and sound awful and rough, honda is one of the few exceptions and the cheapest, their engines sound awesome since they're oversquare, have v-tec and cam rev almost like a motorcycle, I'd definetly get something like a civic over an any sports car with similar price
@@vroe5620 lol you’ve clearly never ridden or been near a motorcycle engine. I’ve got a CBR600RR and it’s a sweet sounding engine when running a good exhaust whether a full exhaust or just a nice yoshi/akro muffler (end can, whatever you want to call it) I also have a Suzuki GSXR600 and it’s got a nice yoshi on it too and it is loud and sounds amazing. Both these bikes you can hear klms away as when you’re pinning it 13,000/14,000 redline it’s very obvious.
K is the way! My super low mile 2008 Si just has a Tune, Catback, and Cold Air Intake and she is an absolute screamer. Super fun car to drive that loves to rev.
You didnt cover the k24a2 which is essentially the stroked version of the k20a2. Even though the head dont flow as good as the PRB, its still not that bad and will whoop some ass in a civic or integra. Oil pump conversion that deletes the balance shafts is mandatory. You can also make the TSX head flow better than a stock PRB and more by having it ported.
To me, the K24A2 is the best value of the K series since you can easily get them at junkyards for a few hundred dollars if you are patient. The low end torque is great for daily driving too, it's nice to be able to effortlessly accelerate and climb hills at low RPM without downshifting. Balance shaft delete isn't at all mandatory unless you are revving way higher than the stock redline, but it will free up a few horsepower and improve fuel efficiency a little at the expense of possibly vibrating more. But for what it's worth, mine runs very smooth without balance shafts.
The possibilities are endless up until the bank goes broke. Truer words have never been spoken. Here's to one day getting a 6 figure job to entertain my idea of a K swapped FD
My ,,Little" Honda stream type 1 with k20a engine... A dream to drive... If you see this car in the parking place you just can't image what it could do on the road... Honda make me fall in love with cars. Cars from 2000 to 2010 are the peak of engineering in my opinion
The best k swaped car ive ever seen was someone put a built and tuned k20 in a lotus elise 111s 😲 what a fantastic idea that car was untouchable round the anglesey cuircite 🤗
i drive a 2008 civic si sedan using same clutch and engine since my dad is the original owner. 227k miles on the engine and its still running strong and i could still push it from time to time loll
Simple efficient and easily rebuilt with great supporting mods market, from 240 ish na to 1500+bhp drag monster setups it’s one of our greatest internal combustion power plants
I got 140k on my K20C2 (it's the one that doesn't have the turbo) and it's still getting stronger as the mileage increases. Very little aftermarket support for this engine, but its perfect as is...especially with the 6MT transmission. I feel like I'm getting my cake and eating it.
@@psewgobind the more something gets used, the stronger it gets applies to biological tissues like skeletal muscle (hypertrophy). Engines do not get stronger via use, lol. You can say engines need to be broken in, but you cannot say they get stronger by using them more.. That’s absolutely idiotic
@@Dailyshart a good NA engine. Especially Toyota or Honda will work better with hard use. Not so with turbo where extreme heat will degrade engine. For NA engines heat isn’t toxic…in fact beneficial since heat is enough to burn off carbon build up but not enough to harm engine. On my last track day, the 150km hwy drive back home after a very hard session engine was purring and returning 46mpg consumption. So, engine does get stronger as mileage increase.
hey that’s what i have as usual when there’s a hot version of your engine though and you inevitably look at mods, you’re gonna read 800 posts all saying to buy a different car like that’s easy to do in 2022
I have an Acura TSX with a k24a2. It is arguably the best variant of the k24 motor and I will be boosting it soon. It is one of the few models with the RBB head which has the most aggressive factory cams of them all.
It is a fantastic engine which is why I own one but it does have one other problem that a lot of people forget about that is the vtc cam Gear can fail so I always recommend to people if they're getting their timing chain done replace that cam gear as well
I came here because I keep hearing my friends over at the gas station smashing a couple of K20 down the highway while I have to study! They keep banging the limiter off those things 😂
The Balance Shaft on the K20a was only fitted to the CL7 Accord Euro R, the K20a in the Integra DC5 did not have the Balance Shaft fitted, the Shaft made the engine a bit smoother when in the V tec range, thanks for the video.
2:10 you got a slight mistake, bare block has a more significant difference between K20A2 and K20A3 than just oil squirters. The K20A2 girdle design is completely different, and brings a huge increase in block rigidity over the A3, thus can handle much more power and RPM's
thanks for sharing this information, this is one of my dream engines in my future car project. With this video, I hope I can build my dream car without any mistakes when buying and choosing it
Had a K20 car. All N/A power and revved to 9k rpm’s. Wasn’t the fastest thing on the street, but was one of the most fun cars I’ve ever owned. Now that AWD kits are more available for the RSX-S, I’ve thought of picking up another one. Or put a K20 in a lotus.
I still like rebuilding B's more, but K's are built better, specifically for boost applications. Many more layers of bracing allow it to stay together at insage boost levels, although the b-series rev's better thanks to it's shorter stroke. Us B-series fans slept on it for a few reasons: 1. swaps were hard, the engine spun the opposite direction as the b, and you needed a transmission and axle swap too. 2. When the k-series debuted, they also lost double wishbone suspension. We ignored these cars, spevifically the ep3 with its abysmal handling. 3. Complete swap kits did not exist for quite a while. They are still more expensive than the engine itself. 4. The H22 is nearly as good, and also spins the "wrong way" like our b and d-series. It also can be adapted cheaply with an existing b or d series trans and axles. You only need a couple mounts and some grinding on the block webbing.
the funny part is the b series is actually the "wrong way". I always hated 4 cylinder engines with front exhaust manifolds because the manifolds go under the engine. Us K-series fans slept on it for a few reason 😂
Just bought a k24a accord (2004) with 566k miles, bought it for $200 runs and drives about to put a new solenoid on bc it has the p2646 aswell as bad 25-3k rpm studder. Excited to maintain this car hopefully to 1M
Really enjoy listening to this 👍 Would love to see one video like this on a common enthusiasts engine like Renault's F4R used Clio 182 , Megan RS , Renault Forumla 3 and the Pragga race cars
If you want to see the full potential of these Honda K2x units, go check out the BoostedBoiz channel. They hold some record holding fast drag cars, powered by boosted K20 and K24 engines. These things are absolute beasts.
Ill put it to you this way. When the k series started taking off the k20 type r was 10k for the swap into a 99 civic. A b16b swap was 4k. Today, those prices have basically swapped. Ill stick with my b16b because of its rarity.
I had my EP3 TypeR Civic from 2005 until 2007. Its K20 drank oil like MAD. I guess when the engine revs at 8000 rpm, it burns more than you might think.
I love my 8th gen civic si with k24a swap and stock lsd 6 speed. I still want a em1 some day, but for now I love my fg2.❤ hope to put the k20z3 with spun bearing in a older 92-95 dx coupe like I had as a teenager with d15. Lol
The only PROPERLY manufactured i4 2+ litres VTEC bangers with balanced design essentrics & huge mods potential to be outsourced for any level of enthusiast to get fun in a small or insanely sophisticated package. I got my K24 in the shop waiting for an overbore 91mm to make a 3.0L I4 same stroke, just waiting for sleeves & machining tool parts, aiming for 1k HP on a bar of boost for regular road use.
Pretty impressive stuff iam more of a nissan guy and these little Honda 4 cylinder engines are pretty amazing! Love my SR20DET :) but the S2K was a really awesome car would have one maybe some day :)
The k20 engine normal aspirated with a few bolt on and a map is great fun easy going power. but k20 is a completely different beast when boosted never gets boring just a bit of a handful to drive in a ep3!
THE F20C SERIES motor IS THE BEST 4 cylinder motor ever made, it produces the highest hp per liter at 125 and it took a Ferrari 458 to barely beat it...not only that but on stock it revs up to 9,000 rpms...
When it comes down to modifications, it´s no longer true. K surpassed the engine both in NA and in boosted aplications. Stock to Stock, F is more impressive for sure.
I own a k20z3 08 civic si coupe bought it a year ago nearing my second year by the end of this year definitely a fun car had some issues from previous owners lack of maintenance but i brought it back to life 151k on the clock.
My Ep3 will turn 20 in August this year.... they get old so fast, hehe.... I love it so much.... 320.000km and it´s running like on its first day... i will ride it as long it wanna ride with me
Although you make only brief mention of it, the fact that the K-series is clockwise spinning is a HUGE advantage vs, say B or H series.Because B and H series were counterclockwise spinning, their use was largely limited to Honda swaps or maybe a few other vehicles that could accommodate a full drivetrain swap. Everybody hated on Honda engines because they simply could not be appreciated in other vehicles. But K-series changed that. The fact that they spin clockwise means that they will work in a wide variety of vehicles, including RWD applications. These days, everybody likes K-series engines because they have been able to experience what they can do in their favorite vehicles.
Sou Proprietário de um K20z3 Civic Si do Brasil , muito satisfatório este motor e confiável nunca tive grandes e um grande carro e motor que já entrou pra História!!
F series don't get much love unless you owned one. From the boost tolerable f22 in the early 90s accords, to the f20c in the s200, to my personal favorite and what I had swapped in my own Accord many years ago...a F20b. If you know, you know...that navy blue valve cover always had people confused
K24A3 has I-Vtec on both cams, not only intake. People confuse K20A3 and K24A3. K24A3 is basically the same as K24A2, just worse intake and 24 degree v-tec due to european emissions.
IVE GOT A 2008 CIVIC SI COUPE I JUST LOWERED IT WITH H&R. RACE SPRINGS. & INSTALLED A K&N AIR FILTER. JUST THE CONE ..&. IT HAS AN AFTER MARKET EXHAUST THE BEST CIVIC IVE EVER OWNED. I CALL IT MY " RICE. ROCKET "
I loved the K20 in my FN2, but I didn't like the chassis dynamics of the FN2 platform much. I would have loved a K20 in my old EK4, but even the now-almost-ancient B18C I swapped into it made for a benchmark-setting driving experience. I should have never sold that car.
The engine in the US spec Fit is supposed to be built strong enough to support 300hp per cylinder. It's light weight has made it attractive to aircraft home builders.
If you look at a Honda bottom end and how they are built, I can believe it with proper balancing and clearances. I seen this fact in a RUclips video on the internet, which I call bullshit on quite often. Especially replies.
Bought a 2002 ep3 si just a month after it was released. Everyone at the time would complain that it didn't have a b series when I'd show them the car. Aftermarket support wasn't anything like today, but even back then you could see the potential in the k20 if you could get over it not being a b16.

I built a 98 civic k24a2 with bokt ons.. And its a great car.after having a 420whp stang my 250whp k24 is qhicker being 2200lbs ..great on gas
I still like rebuilding B's more, but K's are built better, specifically for boost applications. Many more layers of bracing allow it to stay together at insage boost levels, although the b-series rev's better thanks to it's shorter stroke.
Us B-series fans slept on it for a few reasons: 1. swaps were hard, the engine spun the opposite direction as the b, and you needed a transmission and axle swap too. 2. When the k-series debuted, they also lost double wishbone suspension. We ignored these cars, spevifically the ep3 with its abysmal handling. 3. Complete swap kits did not exist for quite a while. They are still more expensive than the engine itself. 4. The H22 is nearly as good, and also spins the "wrong way" like our b and d-series. It also can be adapted cheaply with an existing b or d series trans and axles. You only need a couple mounts and some grinding on the block webbing.
the funny part is the b series is actually the "wrong way". I always hated 4 cylinder engines with front exhaust manifolds because the manifolds go under the engine. Us K-series fans slept on it for a few reason 😂
Would love to hear more about the new k20c
I'm running an K24Z7 And this engine is a beast ! low torque and high revs, the dream and hell of a beast in reliability
What car was this sourced from?
Just bought a k24a accord (2004) with 566k miles, bought it for $200 runs and drives about to put a new solenoid on bc it has the p2646 aswell as bad 25-3k rpm studder. Excited to maintain this car hopefully to 1M
Really enjoy listening to this 👍
Would love to see one video like this on a common enthusiasts engine like Renault's F4R used Clio 182 , Megan RS , Renault Forumla 3 and the Pragga race cars
One day perhaps, thank you!
If you want to see the full potential of these Honda K2x units, go check out the BoostedBoiz channel. They hold some record holding fast drag cars, powered by boosted K20 and K24 engines. These things are absolute beasts.
thank you as always with your excellent videos !!!
the k series and f20 and f22 are the best engines ever made by honda hands down
Ill put it to you this way. When the k series started taking off the k20 type r was 10k for the swap into a 99 civic. A b16b swap was 4k. Today, those prices have basically swapped. Ill stick with my b16b because of its rarity.
I got a k20z1 rsx type s, and it is such a joy to rev it out.
My K24 in the Accord is creeping up near 330k miles and still strong as shit.
I had my EP3 TypeR Civic from 2005 until 2007. Its K20 drank oil like MAD. I guess when the engine revs at 8000 rpm, it burns more than you might think.
My friend's Accord CL7 (K20Z2) ran without oil for a month and it's completely fine.
What a great review, thank you young man.
That is a good knowledge about Honda engine!
I love my 8th gen civic si with k24a swap and stock lsd 6 speed. I still want a em1 some day, but for now I love my fg2.❤ hope to put the k20z3 with spun bearing in a older 92-95 dx coupe like I had as a teenager with d15. Lol
I have a K24 turbo swap in my BRZ. Making over 450whp on stock internals on E85.
I'd like to see you do a vid on snowmobile engines. Bombardier makes some pretty sweet power plants. So do Arctic cat, Polaris, and Yamaha.
This is an amazing video. Thanks for making this!
The only PROPERLY manufactured i4 2+ litres VTEC bangers with balanced design essentrics & huge mods potential to be outsourced for any level of enthusiast to get fun in a small or insanely sophisticated package. I got my K24 in the shop waiting for an overbore 91mm to make a 3.0L I4 same stroke, just waiting for sleeves & machining tool parts, aiming for 1k HP on a bar of boost for regular road use.
Pretty impressive stuff iam more of a nissan guy and these little Honda 4 cylinder engines are pretty amazing! Love my SR20DET :) but the S2K was a really awesome car would have one maybe some day :)
The k20 engine normal aspirated with a few bolt on and a map is great fun easy going power. but k20 is a completely different beast when boosted never gets boring just a bit of a handful to drive in a ep3!
Excellent video man, very nicely done!
THE F20C SERIES motor IS THE BEST 4 cylinder motor ever made, it produces the highest hp per liter at 125 and it took a Ferrari 458 to barely beat it...not only that but on stock it revs up to 9,000 rpms...
When it comes down to modifications, it´s no longer true. K surpassed the engine both in NA and in boosted aplications. Stock to Stock, F is more impressive for sure.
Great video, just ended up turning the volume down cause it was hard to understand my man but apart from that good captions lol
I’m putting a K20A3 head equipped with a VTECkiller setup on top of a K24a8 block the EP3 intake :)
I own a k20z3 08 civic si coupe bought it a year ago nearing my second year by the end of this year definitely a fun car had some issues from previous owners lack of maintenance but i brought it back to life 151k on the clock.
K20 or b16 were majic and special also kicked ass too
This video is exactly as long as my commute home. 👌🏼
Very informative. Thank you for sharing such knowledge in an organized way.
My Ep3 will turn 20 in August this year.... they get old so fast, hehe.... I love it so much.... 320.000km and it´s running like on its first day... i will ride it as long it wanna ride with me
On stock block, a fully built K20/K24 easily can make over 1,000hp. There is a B-Series Integra that makes 1,600-1,700hp~ albeit on a billet block.
Although you make only brief mention of it, the fact that the K-series is clockwise spinning is a HUGE advantage vs, say B or H series.Because B and H series were counterclockwise spinning, their use was largely limited to Honda swaps or maybe a few other vehicles that could accommodate a full drivetrain swap. Everybody hated on Honda engines because they simply could not be appreciated in other vehicles. But K-series changed that. The fact that they spin clockwise means that they will work in a wide variety of vehicles, including RWD applications. These days, everybody likes K-series engines because they have been able to experience what they can do in their favorite vehicles.
Sou Proprietário de um K20z3 Civic Si do Brasil , muito satisfatório este motor e confiável nunca tive grandes e um grande carro e motor que já entrou pra História!!
F series don't get much love unless you owned one. From the boost tolerable f22 in the early 90s accords, to the f20c in the s200, to my personal favorite and what I had swapped in my own Accord many years ago...a F20b. If you know, you know...that navy blue valve cover always had people confused
Im running 15psi boost on a stock k20a2 typeR engine. Maked 535hp 442nm running almost8 months strong
K24A3 has I-Vtec on both cams, not only intake. People confuse K20A3 and K24A3. K24A3 is basically the same as K24A2, just worse intake and 24 degree v-tec due to european emissions.
Another informative and fantastic video many thanks always.
Thank you, Tom!
@@VisioRacer You are most welcome :-)
Lookin forward to your k20c1 video
IVE GOT A 2008 CIVIC SI COUPE I JUST LOWERED IT WITH H&R. RACE SPRINGS. & INSTALLED A K&N AIR FILTER. JUST THE CONE ..&. IT HAS AN AFTER MARKET EXHAUST
THE BEST CIVIC IVE EVER OWNED. I CALL IT MY
" RICE. ROCKET "
Great Vid!
Btw, k24a3 has Vtec on both intake and exhaust cams. It is a 'performance' k engine. cheers
Honda is the best engine builder, cars and motorbikes 🙂
They’re up there for sure, but Yamaha and Toyota have case to be made.
Great video. Gas prices gonna make honda great again.
I loved the K20 in my FN2, but I didn't like the chassis dynamics of the FN2 platform much. I would have loved a K20 in my old EK4, but even the now-almost-ancient B18C I swapped into it made for a benchmark-setting driving experience. I should have never sold that car.
it could of been that way with any engine. they just happened upon a perfect formula.
but an engine is a driver preference.
The engine in the US spec Fit is supposed to be built strong enough to support 300hp per cylinder. It's light weight has made it attractive to aircraft home builders.
i call bullshit on the 300hp per cylinder rating
@@snoofayy6150 ya that’s 300hp per 500cc lmao ya ok
@@snoofayy6150 same here b.s.
If you look at a Honda bottom end and how they are built, I can believe it with proper balancing and clearances. I seen this fact in a RUclips video on the internet, which I call bullshit on quite often. Especially replies.
@@upsidedowndog1256 you do not get 1200hp worth of forged internals on ANY production 1.5 liter period
Bought a 2002 ep3 si just a month after it was released. Everyone at the time would complain that it didn't have a b series when I'd show them the car. Aftermarket support wasn't anything like today, but even back then you could see the potential in the k20 if you could get over it not being a b16.
There was no potential in those motors. The K20A3 was an economy motor.
@@refillz5281 and in general a huge dissapointment.If usa started with the A2 the whole story would be different in the US.
I absolutely love my K20 in my Civic X 🖤🖤🖤🖤
K24/k20a2 in my rsx. Absolute beast and blast to drive.
"Why People Love Honda's K20 So Much?"
VTEC?
POWAAAAA??
