- Опубликовано: 5 окт 2024
- Today in the MotoIQ Garage we're building a hybrid K24 Honda engine for a customer who wants to get the most power out of his daily driven Acura RSX while still maintaining street drivability! Oh and it also has to run on crappy California 91 octane pump pee! Join Mike Kojima as he explains what parts we used and how we built it!
If you want us to build your engine (we build all kinds) visit MotoIQ.com and fill out the form in the MotoIQ Garage Services tab at the top of the site.. or just click here: motoiq.com/mot...

This guy looks like he is gonna start laughing at any second.
lol! I love Mike Kojima :D
Mussh Wins that’s a feature I wish I had
That made me laugh just by thinking about it!
He looks stoned af
Fuck yeah. Died laughing at this comment. Dig your civic. What specs?
Mike is like the Bob Ross of cars. His voice is super relaxing and his energy is very uplifting.
This guy just blew my mind, wow. I’m amazed how happy he is with what he’s doing for a living. That’s freakin awesome.
Not sure if he's that happy or thats just how his face is. Maybe he's mad but he has a happy face? had a pretty monotonous voice lol
He's been involved with Hondas since the early days. I was surprised to see this and see that he is still very active in the scene
@@bbdetailing9123 for those of us in other parts of the world, who is The Guy?
Thank yoy
@@bluewanderer9903 Mike Kojima. He's been around since the early days of import racing, wrote some books and has wrote from various car magazines.
@@bbdetailing9123 oh now that you mention all that I think I remember seeing him or reading his stuff, its coming back slowly 😁
Thank you👍
Dude's glasses are so jdm.
Digivolution 💀💀💀
His car headlights are also yellow 😂
This guy is so JDM
Lol yellow tints started in Europe, got nothing to do with JDM (overused so much it's lost its meaning).
So is this comment! 👍
It's like someone's tickling him 100% of the time he's talking
This fella is a fountain of knowledge.
Imagine if Honda made a K series Straight 6.
Tyler Hand imagine... twin Kseries... joined at the crank 😶😶 all other will fear that thing
They built a v8 at one point.
@@jamaisvu2664 for indycar racing...
zach miller well I guess it was actually Mugen but check out the Mugen Legend Max concept. Pretty neat
It'll compete with the 2jz.
It's like he is super freaking hi and can remember everything he's ever learned and can explain it in great detail. This guy has reached a grand master level.
Would love a vid on the different types of k-series and differences with specs and modification possibilities. There are a lot of vids that explain the differences between the different K series engines (A2, A1, A JDM) but curious how these make a difference when fully upgrading the cams, valves, rockers, springs, retainers etc. As always thanks!
Head flow would be the main difference
You can find that information on Wikipedia
In 2010, I bought a S2000 with a scorched piston. I managed a Machine shop at the time so I was not afraid to get into the engine. I rebuild the engine using a stock K24 crank, K1 rods and Wiseco Dish pistons. We also bored out the cylinders and installed 2mm Melling repair sleeves. The engine was boosted with a V1 supercharger and made 420whp at 13psi and 300 flywheel hp natural aspirated. For the street, I preferred natural aspirated version of that car because you could use all the power all the time where with the supercharger you had to be careful not to oversteer the car and loose your ass. I sold that car and it is still riding around town 10years after the build. Everything was done on a budget with mostly stock parts. Honda did it right!
Sounds like a sweet set up. Is the K24 crank a better balance for the F engine? Im curious to know why you preferred it over the F crank.
Mussh Wins the factory k24 Crank increased the stroke and made it a 2.4 Liter over the stock 2.0. It really gave it bottom end, my butt Dyno estimated about +50ftlbs. The F20 is rated at about 150ftlbs. So having 200ftlbs really made the S2000 fun to drive.
If I could just get one of those in my f23 block and bore to 87...
I cant imagine many people i could listen to talking about engines, but I can with this guy 👍
This guy is Bunta's boy and he tuned Takumi's 86.
While all the other guys are yelling MONICA, I'm on the side yelling takumi like a japanese teenage girl.
all he needs is a cig
Loved the vid. Wish you guys would show some shots of the motor while it was being assembled as well as realtime shots of the components.
Keep smiling bro. we need more happy people in this world.
Mike's videos are some of my go-to ASMR things on RUclips.
I want this man to teach me everything
I'd hang out with this guy and listen to what he has to say. Awesome explanation for the metallurgical properties and the mechanical properties.
Read through most of the comments and can't agree more! No BS, no music, no stupid cutaways, just the facts ma'am. LOL great video, subscribed!!
I could watch Mike talk for hours and hours. Absolute motoring legend.
SuperTech valvetrain parts, available at your local Walmart oil section.
love this type of stuff, hope to see this in your Ep3 build!
The conclusion of this video is

WPC everything important, and smile eternally.
Honda has that effect on people.
bro, from start to finish.. I been cheeseing so hard. something about this guys just makes you wanna smile all day. great vid brother
Nothing but love for all motor K's.
I love these kinds of breakdowns and knowledgeable talk-throughs! I'm not a Honda guy by any means but damn I might just build one with this info for a reliable fun project 😉👌
This is the person I want to build my d16a6 in my crx. Seriously would love to learn from someone this full of information
I want to build one so bad ! I have one that died because of lack of oil. I would love to build it for my 2000 civic. Thanks for the video! If I get well, Lord willing, I’ll hear that civic thumping the pavement!
I'm a B16A guy, but I swapped my cr-x back when you had to weld the motor mount to the engine bay directly.
I'm a Subi guy now.. but Honda is where my heart is/was. The K20 is an amazing engine!
@Caesar G loll Subi, Subaru, Scooby? It’s just a name.. I love my Subi ❤️ 💐 🌺 🌸 💋
@Caesar G Sounds like you didn’t get enough love/attention when you were a kid.. that, or you were molested at a young age haha 😆
This is the info we cali car heads need. This guy is a master mechanic
Nickel is primarily used to prevent creep at higher temperatures. Not for tensile strength. That’s more steels department
Your not going to use nickel for strength when it only benefits from 5% difference in tensile strength. A forged component would still be cheaper and plenty capable with the new orientation of the grains. Yes corrosion resistance at higher temperatures but this is a heat engine, not a jet engine where were subjecting the components to above their melting points. The only material commonly found to corrode at temps like this are aluminum alloys, where hydrogen is more susceptible to diffuse within the material as we approach the melting point. Which is still not even close in the Carnot cycle these motors are running.
160hp per litre from a k20 is actually quite easy, one of my customers has 347 flywheel from a 2ltr with the right cams, rods an pistons on standard crank, all i do is change bearings an rings each season, but this will be season 3 so a new set of liners this rime round....
But EVERYTHING is cryo treated, then surface treated after 👍
This engine lives between 9500rpm and 11000rpm at every event, 16 events a year 😊
This is why I love K motors! We did this power on shit California 91 octane pump gas.
Put it in the EP3!!! 👍
Mike, you are so fun to watch, you make these videos easy to understand and I absolutely love learning from the best! On to the next one! ;)
doing this in the spring. accord 2004 lx sedan ftw!
My Lord, I wish this guy lived near me to help with a build! Very knowledgeable!
Hahaha. Dude. Remember when Mike tried to get Type R power out of the SR20 for a magazine.
Now he's making 300 with a K!
Technology is awesome!
It’s amazing that you can run 12-1 comp on some engines with pump 91, the old school American motors start pinging at 9-1 😂
It is due to bore size and combustion chamber design.
This is the GOD of Motors! I love How calm he speak about the Motors!
Best Teacher ever! 🤟👍👍👍🙋🏻
I once stroked out my fc20 engine with a Honda accord crank. We used 2mm melling repair sleeves. Had to make a custom spacer for the timing chain and that engine definitely made 300hp. Wished i ever sold it.
Messed up a seal in my engine and I have to redo the install but at least I watched this video today :)
Thanks for talking about the forging process and how it relates to grain direction. Really cool to hear about that, along with fatigue stresses and toughness.
K24 also found in the Element!
Be nice to have some of that extra zip...
Island Aerial well it’s 164hp and 160lb/ft torque, not like the k24a2 with vtec on both intake and exhaust at 205hp 166lb/ft
he has a K24A2
I remember a lot of Mike Kojima's articles from SCC back in the days. Dude's been legit! 👌
Who remembers the D16z6? So much fun.
An yall should listen to what moto have to say, they give out good advice for free, appreciate it 💯
Happiest man in the world.
That's the kind of K series I'd love to build and stuff into my integra.
I wish I could be as happy as this man looks
I wish I had his knowledge and experience in building Honda motors! He’s probably forgotten more than what most of us will ever know.
I don’t know how and why but this dudes face is straight from cartoons which is great! Love his vibe
The thing about 2618 needing a ton of bore clearance is a myth... yes, it grows quicker than hypereutethics and needs it if your habit is to nail it from bone cold. If you don't want the skirt rattle, learn to load it gently until running temps are in and run 0.003" / 0.076mm clearance instead of the thou+ more the card says you "must have".. done that on several 80 to 85mm forced induction setups and never had one seize up.. rattle is gone and ring oil control is better (very short skirt piston).
Mike Kojima is the man! He knows so much about Hondas, which is scary bcuz he's a Nissan guy! I dnt think anyone has built a fresher Sentra! Isn't it called "The Dog" or something?
I'm more into 4G63s but when Mike talks shop, I'm all 👂 👂
I wish videos like this existed when I wasn't starting off learning how to build engines haha great video
I always wonder/wish Honda had made a variant of the K but at least the F series with 5 cylinders.
Partially to honor their F1 program that was around when these engines were designed. But also to honor some modernization on the thing that made them famous (NA 4 cylinders). It’s a nice way to get some extra torque, and not experience much weight and packaging problems.
Always seemed like a natural fit. But I understand that a professional company is risk adverse. And that they achieved all they needed to with a simpler, cheaper and more efficient conventional design.
But I guess I wouldn’t be an enthusiast if I didn’t wonder about a Honda 5 cyl
His voice is so soothing I listen to it to go to sleep lol
Seen him on Hoonigan multiple times. Dude knows his shit.
Mike Kojima is such an OG.
He seem like he's about to bust out laughing 🤣
Now tell us about the hyundai excel. Great content as always #MotoIQ
This is Charlie from boosted boiz 40 years from now..
Like always Mike, You are a star! I enjoy listening to You.
This guy is a guru!! I’m subscribing!
I can't wait/really hope to hear back from you about my inquiry on this build! Would love to throw it in my ep3 and see what it can do on new york 93/e85.
This guys perma-smile is making me smile.
He seems like a wholesome good guy
I'm a simple man. I see video about how to make 150 hp/liter from my Honda motor, I *click*.
Great stuff, would love to see a video like this on an F20/22. 👍👍👍
Seriously I need to see that video
Simple answer, K swap.
Can you do a magnum 360 v8 mopar?!
It's common for 130-150hp per liter for slightly modified motorcycle engine or stock sports bikes. I have seen bored CBR150Rs from 149.++cc to 170-180cc resulting to 27-30hp in the wheels when dyno using hi octane pump gas! Bikes engine and cars are both piston driven, and 4 stroke. The only difference is car engines have more stroke. Thus they're can't rev as high as motorcycle engines. A cause they're designed to produce torque at a lower RPM, hence lesser power..
Awesome video!!! Great stuff! The title is not quite 100% 150hp per liter. He claimed 320hp out of 2.4 liters = 133 hp per liter. Still damn good!
what he's trying to say is generally k series is capable of 150hp per liter and still be reliable. not this particular motor being shown since this is a milder build.
I would love to see a video like this for a Nissan KA24.
F-20/22C is amazing too.
They're so similar you can pretty much lump them together... F has a few fancier materials but otherwise mostly equal and a lot of parts swap between them with little to no modification.
I see Mike. I click.
Here in Canada we can get 94 octane from any old Husky that has 10% ethanol, or 94 on 0% ethanol at Chevron over in B.C. (it’s like $1.75/L last I went so bring cash lol)
Do you use ron or aki in canada for octane? Last time I was up there I didn’t drive so it didn’t matter. I’ve never seen anything higher than 93 in the states on the pump. It would be nice to have non-ethanol gas for my carbed bike but it is so rare.
Do you have E85?
Thanks for sharing the blueprint ❤️
Cali: "We are pioneers and will lead the nation in environmentally friendly EVERYTHING"
Texas: "Then why do you have 91 octane...we have 93 🤣🤣🤣"
If honda ever made a RWD car that isn't a million dollar NSX i would be so happy. Their engines are phenomenal. that goes for their motorcycles and dirtbikes as well.
I'm in love with the k series engine, it's just never been in a platform that appealed to me. Civic, integra, accord... all FWD economy cars. I wish they made a supra or Z equivalent back in the 90s when they were making engines like this.
Like the S2K?
@@motoiq S2k is a phenomenal car, really close to what i want, it's just a little small, it's more akin to a Miata, Z3, or Boxster roadster type car. It's got the engine, the balance, the timeless design and while i'm sure they're fun to drive i couldn't see myself dailying it.
Just my personal opinion I like a more GT type car something almost mustang sized with 2 door or 4 doors. Nissan is my least favorite of all the Japanese brands but something exactly like a S14 is what i want.
The WRX is cool but idk about their reliability compared to a Honda or Toyota.
It's almost like the car I want doesn't really exist and if it does, it's a 100,000$ collector car
I agree, all the JDM cars I like are from the 90s.
My prototype makes pump gas act like very high octane fuel. Even advanced my ignition timing to the maximum setting.
why the fuck is this guy so smily!? i feel like hes genuinely really excited about what hes talking about
not a Honda fan, but 150hp/l is hard to argue with.
Very nice explanation, with great details! Thanks for posting
Would be nice to see it in the car and dyno
yup, just like a honda literbike engine. high compression, lightweight internals, minimal components, efficient and unique design that revs high and packs a punch.
Love the video but there is a slight continuous larsen that is irritating
This guy is awesome! Instant subscriber
Do a video with a b series a2
F20/22 👍
Can we get a full build sheet of the parts used in the engine?
Keep an eye out for the full article on MotoIQ.com
@@motoiq when does it go up?
And the approx cost for this kind of build please?
Could you do a 2.2L version, either destroke a k24 or bore a k20……?
Yes. Eagle came out with a crank to do just that.
One day I'll get enough money to pay Mike to do his engine and suspension magic on my RSX lol
Dayum a k24 and here i am crying in the corner with my f18
An f18? I'm going to google that
Fantastic video... inspiring even... I want to download this.
If they can get those numbers out of a 1nzfe 225 horsepower would be the equivalent 1.5 liter sounds possible with a big turbo con rods and pistons
The high pitch in the audio guys ,
hmm, not hearing it on our end.. 🤔 what browser are you using?
@@motoiq I hear it too. It's not the browser, it's in the audio track. It's a resonant peak from something metallic in the room that resonates with Mike's voice. It's around 6-7 kHz. A low-pass filter would've quietened it down.
@@motoiq I'm also having the same issue, makes it hard to listen to what's being said
@@motoiq Same here. It sounds like a high frequency reverb. Best thing to do might be to get a cheap lapel mic. Great content though! Thanks for the easy to understand walkthrough
91 Oktane is good😁
A big WTF from Germany!!!
Planning the same build was trying to decide on cams. Never seen a smooth idling stage 4 cam, but I love the drag cartel lineup and Jerame has always been a lot of help to me through emails.
What size injector do you run on that setup if you don’t mind me asking? Great video
We use the OEM injectors off of a K23A1 RDX engine that flow 410cc/min
Thanks for the reply, I’ve seen guys running HUGE injectors and I wanted to see what was necessary to make 300hp without running out of fuel.
I would love one
that was very specific and very interesting
FYI, you showed keepers when you said guides around @9:20
You quite often see K20 heads on K24 bottom ends - why would you do this? And why didn't you do this here?
Actually if you watched the video we did!
