Was gna say the same. I have JDM h22a swapped car and stock r18 civic .. I dnt even own a k series and I fxxkn loved every minute of this video. Bro your the man. Make videos for everything your info is spot on and I love it !
As a Honda tech I must say this was wonderful. There's a reason the K series has been around for over 20 years, it's the chevy LS of the import world. It's very modular, robust, and modifiable. Plus working on them is significantly easier than a B-series because of the cylinder head design. All comes down to great cylinder head design, more airflow= more power.
Back when I used to have one of my first S13 240sx’s in 2007 me and my friend would sometimes trade cars for the day. He had a CLEAN RSX Type S that was still fresh at the time. I used to LOVE driving that car around and taking it into the high rpm’s. VTEC cracked so loudly and it was such a blast. Fast forward to 2016 my friend, Honda and overall JDM head, would pass away. Now the year is 2022 and I own my first Honda EVER. A 1992 Civic SI hatch. I’m planning on going K20A because it’s the first K series I loved so much. I wish so much I could show him my current car and take him for a drive. My build is inspired by him.
Feel ya man. I had a similar situation. Flew 1000's of miles to grab a car a friend recommended from the classifieds (a '95 SC VR6 Jetta). We talked about it for months. Never told him I pulled the trigger, and was just gonna park next to him at work, so when he came out, he'd see it, surprise style. He passed the day before I got the car back. This was 2006. Coincidentally, he never seemed too excited about my '92 Si tho, that I've had since 2002. (Captiva Blue, AC intact, OG D16Z6 w/ 303k). Cars come and go, but it's a lot easier to get another car than a good friend.
The K24 was a remarkable powerplant. I've been driving an 01 Accord F23A1 for twenty years now and it's a terrific car. My wife had an 06 Accord K24 for several years, and that car drove me NUTS. It was a bigger, heavier car, with a higher displacement engine that made more horsepower and more torque than mine and was both quicker and faster, yet consistently gave 2-3mpg better even driven hard. Made no sense at all, but there it was. :D :D
The Z7 does come with high compression pistons though so throwing a K20Z3 head on it and a type S oil pump will have you pushing ~260-270whp with lots of bottom end torque and 9000rpm
@@1mikewalsh it's fine they been racing 300+ front whp in Britain, Japan, continental Europe, and Asia overall since the early 90s. Won't be ideal but with the correct setup they can be real fast and stable
Z7 is also greatly designed for boost and is still a top competitor. my z7 is only intake and DP and im door to door with 5.7 hemis. but I used to have a fbo e85 ported manifold K24A DC5 and that was fairly fast for a basic all motor setup.
I just went for a ride in my friend's K24 swapped BRZ. Car should have come like that from the factory. He doesn't have any crazy mods, just the normal package from Kswap and he is making 224 RWHP. Oh and it sounds amazing.
@Chad Klein that is at the crank. He is making that at the wheels. Also, the 2.4 still has the same oil starvation issues on the track that the old 2.0 did. This engine has a way better power band and he isn't even done yet.
@Chad Klein it makes that with the Kpower engine swap kit. There really isn’t any special power adders. It’s a K24A2 I think. 5.0 and B58s are cool and all, but I still like four cylinders in certain cars. The Supra wasn’t out when I bought mine and I have already had 3 Mustangs. I’m still on an FA20.
One of the most interesting things to me about it, is the fact that the 2jz is also perfectly square with a bore of 86mm, and a stroke of 86mm . Great info, great knowledge!
@@unusualelectronic So did the Nissan SR20DE, SR20DET, Toyota 3S-FE, 3S-GE and 3S-GTE. They share something in common, all 2 liter engines. 2JZ is like an extension of the 3S.
As a big honda guy I gotta say this video was very well done. But I need to say that on the k20z3 you can rev to 8600 reliably (stock rev limiter is literally 8300) on the stock oil pump.
I am not sure this is true in endurance race applications. Rare case I know, but might explain why a lower redline was stated. There is a huge difference between street reliable and being between 6000 and 8600 for a few hours in hot weather with no risk to the valve train.
Would love to see an in-depth analysis on the differences between superchargers/turbos (ie what would work better in certain applications) and how they work on this channel. One of my new favorite channels so keep up the good work!
Wow man, I just discovered you on my feed and I love the way you go over everything. You take your time to research and explain in detail without going off topic. Love your work and you have earned my respect and subscription. 🙏💯
I'm always amazed at how clearly you explain the subject and break it down into such detail. You make it very easy to follow and understand. Thanks and keep up the good work 👏
As a Honda mechanical engineer I will say CHEERS sir! You got everything right, I mean all of what you said, with not one error. I was very entertained by your presentation and energy. Thank you!
Do you work at Ohio manufacturing? What is it like? I’m actually trying to get internship. I’m mechanical engineering student at University of Houston. I’m a big Honda guy as well. I’ve been driving my RSX 5 speed for 7 years. I fell in love with it.
@@twistedmembrane6988 It's the same engine as the 04-05 tsx engine. Same cams ect from what I've read. It's a 200hp engine with vtec on exhaust and intake sides, true vtec.
You my good man just earned a new subscriber. You seriously just answered every single question I had about what K20/24 variant to go with for my build. Bravo.
Good video, I had a 1.6 dohc 1999 Honda SI coupe. But I flooded the motor with a cold air intake during a flood. Swapped a stroked 1.8L, skunk 2 cams, qauife differential LS transmission, lighten flywheel and crower rods! That motor was so torque, I barely had to reach v-tec! Those were the days!
My element makes 200 HP thanks to swapping out the pistons and rods plus slapping on a K24A2 cylinder head. The extra top end power helps out a lot when trying to merge onto any major highway due it’s heavy weight.
@@brenreidy8763 Yeah its set up, but he never said hes got that going on though. literally for that of pistons and head he could have got a used cleaned up z7
Grew up around fast and furious days when everyone had Hondas civics early 2001 and I was the underdog guy with a 1991 Sentra se-r with a NA sr20de that I swapped out for a Neo VVL SR20VE which was very similar to Hondas vtec because it also had a cam phase lift. I was always trying to embarrass all those b series out there but still much respect to these motors. Honda is the king of 4 cylinders.
My room mate had a del sol d series 1.6 built with a turbo And it embarrassed all kinds of cars. If I had to choose I would go for the 1.6 just because 2.0/2.4 gets like half the fuel economy.
@@fastinradfordable I had a buddy who also had a del sol. Now keep in mind these are early 2000’s we’re bodykits, underglows and obnoxious wings, loud big exhausts we’re a thing. But my friend took it to the next level. His front was 350z and his rear was a r34 GTR and wasn’t half bad looking actually. It was all show but no go tho since It was a stock 1.6 lol
Awesome, I had the same exact setup in a 92 SE-R (SR20VE VVL) and for the same reasons, wanted something different, a true underdog car, and wanted to stomp on Hondas and others, I got to a 12.8 NA with slicks. Still one of my favorite cars, matching the excitement I get out of my S2000
@@revhappyrs2k yeah man I miss the damn thing. I ended up selling it to a 17 year old kid years ago. I had plans on putting ITB’s and getting it to rev higher by putting in JWT camshafts but the release of the ser-r spec v at the time made me wanting a newer car and a huge downgrade since those QR25de are good engines but not as rev happy and lacks top end. Torquey though since then I’ve been sticking with Nissans. Even owned two z32 twin turbos that were fun but a headache to deal with. I once had a 450whp 300zx but it weigh like a boat and the lack of mods support and engine space back then made me change platforms to a 350z, g37 coupes and sedans and now I own a 2016 q60rs400
Good work bro loving the content!! I would love to see you go through each ej engine( specs, power, reliability, tuning potential, etc.) Just an idea. Keep grinding brodie💯
I love how Honda’s K20 has an innate 86mm bore and stroke built in and is legendary; whilst when Subaru tried to build the 2012 BRZ/GR86/FRS engine to Toyota’s specifications of an 86mm bore and stroke (in order to pay homage to the AE86 Corolla) their engine became infamous for falling flat on its face with a torque dip and reliability issues when modified. It’s almost as if Toyota should have just paid Honda (exorbitantly) for their K20 engine out the gate to put into their new rwd Toyota Corolla AE86 revival
They are a big and heavy engine though. Would not say they are the best, they still use rockers instead of buckets. Good for peak power, not continuous power.
@@chippyjohn1 Does matter, with very little work. You can get 700whp out of a K20A2/K24A2 out of the stock bottom end, with a single turbo. Put that combination in a 2000-2500lb Civic. For a fraction of building anything else. It even cost less to build a Honda/Acura then it does to build a GM LS V8 parts cost and mod for mod.
Amazing video, voice and attitude towards the information was enjoyable. It's quite a bit of info most of which a lot of the ones that have live the birth of the K have gotten to know and being able to properly squeeze all of this in 8 minutes was amazing. I feel like the F20/22C would have offered some great comparisons as well as it was the last attempt and truly the first attempt at 2.0 + chain drive incorporating the bitter sweet FRM + high comp. Ultimately landing with the addition of VCT which pushed tech into older minds. Honda has now moved into forced induction where most of this momentum is focused on turbo efficiency.
As an owner of a k24 i can confirm. 400.000 km and still going.Kept it na with just some minor upgrades(4-2-1 exaust,reflash and a better intake). I think the k series is the best na 4banger ever made.Very reliable,good mpg,parts and engines everywhere,huge tuning support and potential. No other 4 cylinder meets all these qualities quite like the k series.I love these new videos.I hope in the future you can show us some of the projects you work on in detail!
The K20A3 does have actual VTEC. The valve lift on the intake side is asymmetrical until VTEC engagement, which promotes high swirl (and more torque) at low RPM, while not choking the engine in the midrange. This is still VTEC, even if it operates differently than the VTEC found on the B series (and more like you'd find on some D series). It's also worth noting that "K20A" can refer to what is effectively the K20A3 in Japanese vehicles, as well as what's found in the RSX Type S or the Type R. They simply did not stamp the blocks the same as those destined for other markets. You have to look at the code on the head (or under the valve cover) to determine which engine a K20A is.
Where is this code on the head or under the valve cover? I'm going to look at a K20A stamped block tomorrow. Would the JDM version of the 'K20A3" have the single exhaust lobe where as the A2 has 3 lobes on both cam shafts? I only want to buy the engine if its the A2 model.
@@rsndriedrain2752 The code is stamped in a few places. I believe you should find one above the header, right in the center. The "K20A3" version will have a single exhaust lobe. All of the high performance variants will have 3 lobes on both camshafts, though that doesn't tell you if it''s an A2 or Z1 or Z3 or Type R equivalent.
"Actually VTEC" refers to the high lift cam timing change, not the "economy" intake valve deactivation, by the Honda community. This engine DOES NOT have VTEC that changes valve lift.
@@tanneroxford9431 Honda calls it VTEC. It's still Variable (Timing & Lift) Electronic Control. The intake valves are still having their timing and lift varied (even if you don't understand how it works). If we're not going to trust Honda to know what their own technology is called, who gets to decide?
Agreed I recently did a swap for my 03 Honda Civic ex. I went from a D17A2 VTEC motor to the K20A3 i-VTEC motor because I still wanted to have an eco daily. There is a huge difference not only in power/torque from the motor but in the VTEC cams. It may not be like my friends type s, however when it locks in you can absolutely feel and hear the difference.
After having owned every popular engine out there, I can't deny that the K series is my favorite. It's so light, so reliable, sounds so incredible for a 4 banger, and can handle anything you throw at it. And the aftermarket support is so much cheaper and easier than just about anything. It's a jewel of an engine.
Hey man don't forget about the K23 in the first generation Acura RDX! The red-headed stepchild of the k-series that was the only one that came turbocharged STOCK. Downside is at the engine block doesn't mate to anything other than the Acura trans BUT the head is swappable with any K-series AND water cooling ports for the intake with a turbo that sits on top/back of the engine. 2.3L with the same bore as the K20 and if you can get a hold of that RDX engine you get piston rods OEM Honda that are 30% beefier than the TSX and can handle more torque than any of the other K-series (because it was turbo designed) Salvage a first gen RDX and you get: A turbo RDX injectors Beefiest OEM piston rods you can get. K-series head, with turbo ready exhaust and water cooled intake manifold. I'm doing an RDX Frankenstein build right now with my k24 in my Honda Element. Everything just swaps in and I bought the engine with the turbo for only $500 bucks with only 120,000 miles. Want a budget k-series turbo build? Go that route.
K24Z7 is also on the Acura ILX, available up to 2022. There is also the K24W series that appeared starting from 2013 on Accords, CR-Vs and Odysseys. There is also the K24W7 which powered the Acura TLX. There is the K24V5 that's used on the Asian market CR-V; the K24W5 used with the international Odyssey and the K24W used on the JDM Odyssey; the K24Z6 on 2012-14 CR-V; the K24W9 that was used on the USDM CR-V before the 1.5 liter turbo took over.
I've got the k24z3 in my 2gen Tsx, 201 HP stock. Its now on the Ktuner with bolt ons, no turbo yet and makes great HP. I need to ditch the paddle shifting auto and go manual so that the trans dont blow. Great video keep'em coming.
I've got the same engine in my 2013 TSX, bone stock right now. Been trying to figure what's better power wise. Drop another built K-series in it or Bolt ons & a Supercharge the Z3?🤔?
I have a 2004 Acura TSX with the 6spd transmission. That 6spd transmission is really smooth as opposed to my RHD S14 SR20DET's transmission in my opinion. I trust my K24 engine more then my SR20DET engine in regards to reliability. Where as my S13 vert has the stock KA24DE with an auto transmission.
7:19 "Usually the fault of the previous owner". Amen to that and so glad someone else see Honda engines the way I do. Finally someone that can see through the misinformation and disinformation about Honda engines. These engines (B, D, F, H, K series) are so tough the only way to kill them would be when the owner neglects or abuses them. It is next to impossible to kill these engines daily driving them (on public roads). Near guarantee to lose your licence, crash or have your car impounded before you can kill these engines on a normal road use no matter how long or hard you drive them.
When you say accessories on right vs left, I feel it's important to educate new persons to Hondas what that means. One engine spins counter clockwise, and one spins clockwise.
This man is big brain as FUCC. And his passion for engines is fucking contagious.... And I *already* have been an enginehead since I was a wee kid. Never thought *I* would have my dedication to the hobby/community challenged by this guy. But man is it refreshing. Please give me more. This is the most perfect format on the entire platform. *Instantly subbed*
K24 bottom swap and supercharger if you want more efficient and reliable power and nothing super crazy between 350-450whp range is great for a daily sleeper!
@@jaebee9805 I had the chance to do the k24 k20 but at the time I didn't have enough money so I just swapped my blown motor with a newer k20. I think I'll just supercharge it with the merc racing kit if anything
Great video, covering all the variations of the engines. Great resource of info for people just getting into the Honda game. I'm thinking about it simply for the availability of the engines and the insane aftermarket support. Instead of building up my ST retaining the Ford Powertrain, a K-swap might be the ticket. Ya ya its blasphemy but who cares. A good engine is a good engine. If I can build one, maintain one and modify one as easy as possible it's a no Brainer decision. Now to research if it's possible. Gotta find out if there are any adapters out there for the trans
Thank you so much for this breakdown of the k series motors. I'm in the process of looking into k series swapping my 8th generation civic. This helped out a lot!
Outstanding delivery. Concise, coherent, easily digestible information, great image layout. Been wondering about k20/k24 for a while now. Answered a lot of my questions, and then some.
Ariel Atom of North America used a tuned K24Z7 240hp on their Nomad and Atom 3. A turbo version of the Ariel Atom 3S makes 365hp, later a final version Atom 3RS makes 425hp.
@@chaztitan6457 That’s because of the compression ratio in the engine. That engine was built to have the biggest turbo posible and hold the power. Both are great engines the 4g63 just has the the record for the highest horsepower per cylinder of ANY engine.
@@alexvazquez3607 And what is this record just out of curiosity? I'm curious because if it's around the 2000 range, then look up Speedfactory civic with a 2000hp b-series honda engine. Also top fuel dragsters make just shy for 2000hp per cylinder.
@@alexvazquez3607 4g63 is a 2.0L motor with like 200hp (stock in the cars) the Focus RS has a 2.3L motor with 350HP, i think that's more impressive for just having 300cc more comparatively ofcourse these Jap motors are probably much more reliable tho, but still, +300cc and +150HP, thats about 88hp per cylinder in such a small engine
watched this entire thing, was already planning on buying an imported k20A and looks like im going to have to follow through since im not too sure about trusting junkyard motors especially since most in the yard doesnt have vtec on both intake and exhaust side thats so sad
I would suggest you go ahead and go for the K24A (JDM) or K24A2 (USDM TSX). The extra displacement is worth it. Be careful though because some of those JDM K24A are the shitty half vtec. I have a 525hp B18 and I'm gonna turn it up a bit more, but if I had it to do again I'd go K24.
I-VTEC benefits from the "v-tec killer" swap with the bigger cam lobes and rockers from the exhaust side on both cams. Not as good as traditional Vtec but is an option for budget builds or people exploring that route. K20A3 are good for budget boost
Personally I wouldn't do vtec killers on a street car. Unless I was a kid and not concerned about drivability. You can definitely make power with them though. But the A3 has weak rods in oem trim. Won't take as much abuse as the more performance oriented variants.
@@leonardwashington6456 many JDM k24a are full vtec bro. I have one that came from a JDM Accord euro R. Anyway, I swapped my Z1 head into because I thought it'd make more power. Kind of a pointless swap in retrospect
I love my k20z3 in my fg2 civic si. I got the car back in 2013 with 42,000 miles on it. I put a AEM intake, K turn header, skunk 2 full cat back and a IBR high flow cat. In 2017 Honda released the type R in America Love to have a type R but the dealerships put a 10-15,000 mark up over MSRP. Honda if you want to know why the market for the type R fall so fast and the 2020 yellow Special edition was the only type R that sold in 2020. All I'm saying is that 10-15,000 over the MSRP you can buy the mods to eat any type R. Start selling your cars straight to the buyer. Don't even drop ship to a dealership at all. The ones in my location are starting to keep people cars and ask for ransom. Honda fan since 1995. Ps I hate the Fast and Furious franchise. All it did was made parts and cars more expensive.
That last statement is unequivocally false. While it may have originally bumped car and part prices up, f&f also introduced an entire generation to the world of cars and modding, and that extra interest meant a lot of people grew up to work in the auto industry in one way or another. The more interest a scene has, the more competition business' within that scene have, and the more competition business' have, the more time and effort goes into making parts affordable.. Progress and innovation bring with them the r&d that leads to cheaper parts over time. You can get a set of wheels today that are as good as a set made in '95 for much cheaper, suspension parts have become more advanced but stayed relatively similar in cost in the same time-span, tyre technology is exponentially better than it was back then and you can now get sport/track focussed tyres for cheaper than you used to be able to get them.. Inflation is also a thing, which I think is probably a factor in what you're talking about.. Inflation has absolutely 0 to do with fast and the furious tho....

@@UAE_8100 you said you want to mod but then said can't figure which to buy. So you coffused on which mods or which engine is best. BTW there all very similar but in our opinion if dropping into a swap, we like the Gen 2 engines the best. Gen 1 depending on which motor it is have some cast parts thY aren't good, while others have forged. Gen 2 basically all have forged internals but only cast pistons. Gen 3 most have VCM and it causes piston ring blow by and burning oil. So Gen 2 has the majority best engines through all years/models. If you want mod suggestions it's too much for YT comments.
