The first K20 for the US market was in the RSX in 2002, the K20a2 came in the Type S, I bought one in March 2002 and have been driving it daily since then, I’m up to 454,000 miles on the original motor, original water pump, oil pump, timing chain, with only needing the valve adjustments, I honestly feel that the transmissions can’t hold up to these engines, I’m on my second trans, great video and helpful information
Just bought a k24a accord from the OG owner with 566k miles Everything works and runs good other than VVT solenoid being bad about to swap that now hopefully it fixes it
@@Rightchuare thanks for that info, I plan on doing timing chain since it's original, any other recommendations? Besides valves? Vtec solenoid did fix it btw
I got a K24a in my EP3. Made 221hp to the wheels with 2.50 inch exhaust, 50 degree VTC, RBC intake manifold and a 3 inch intake. With a bigger exhaust and a head package these motors can easily make 250 to the wheels with no problem. Looking forward to seeing your build progress.
I was also going to bring this up, that’s what the term is used for and it must have been a script error or something because he mentioned not all of them had it on the exhaust. Before that statement
Great informational video! Keep them coming! One correction, at 3:23 you mentioned the model cast into the block "RAA 2." The 2 is actually the die number it was cast on, not the model revision.
Nice vid, good info. I had a 2008 SI with the K20Z3 and it was the best sounding stock 4 cylinder engine I have ever heard. WOT at 7000-9000 rpms was insane!!
When I had my accord I ran k24a4 block with k24a2 (TSX) Head as well as k24a2 (type-S) Oil pump. When going this route you need to remember that the pistons need to be good with K24a2 TSX Head and not run into what's called a Valve to piston contact. So much fun back then,
Hi there, I do have a 2006 honda accord engine that I would like to modify so I can hace true vtec set up, what heads should be my best options? Thank you
I have had a kia, 2 nissans, and a toyota and all of them gave me problems at one point. But i have owned 5 Hondas and they are just amazing the engines just run nonstop with zero problems you just need to keep up with basic maintenance.i have said it before and ill say it again i will be a Honda driver for LIFE they are the best!
Alway been a B Series or H Series guy but just got a 2004 CL7 Euro R and am swatting up on K Series now, great video with simple but valuable info, thanks!
Bro, honda doesn't use a VTC exhaust cam gear. VTC actuation is only controlled on the intake side which is why you can switch from 25 degree VTC gear to the 50 degree gear. Only way you can change cam timing on the exhaust side is with a adjustable exhaust cam gear.
Maybe I'll have to rip that cam sprocket apart. I am going to be switching to a 40 degree gear for my intake I know that. I'm still learning as I go. I know that the fuel in my area will be the only drawback since E85 isn't readily available.
Good comment, i have pointed that above in a comment, it is easy to spot that vtc is used on the intake side only because when you removed the camshafts from the k24a2 block you could see that there are 2 oil passages under your left hand for the intake, used for advancing and retarding the timing, but only one passage on the exhaust side used for lubrication. Also if you inspect the sprockets closely you can see that the intake one has a ridge because it is made of 2 sliding pieces, whereas the exhaust one is a solid block, even if it has about the same thickness. It is thicker for balancing the 3 lobe pairs that are heavier than a single cam design
I agree with you, on the engines we're looking at here. But Honda has definitely used variable valve timing on the exhaust side in other engines. The reason why was to eliminate the need for an EGR. Learned that at Honda school, kind of an interesting approach to emissions. Not nitpicking your comment, just thought someone might find it interesting because I definitely did when I learned about it. Cheers 🍻
I also have an 8th gen Coupe and I've seen little bits here and there across the forums about the Frankenstein build. I'm really excited to see a good, detailed, quality series following the build for this car.

There are so many variants of the K, contemplating buying a used one and slowly building it up to eventually replace my F20 in my 02’ S2K. My motors damn strong and I love the high rev that it can do. I’m reading up and watching videos to see, wanted to see what’s required to try and get a higher rev out of the K to come close to the F20/F22? Thank you and very good videos.
Thank you guys for correcting me. The "VTC actuator" for the exhaust is not what I said it is. Honda only has VTC on the intake sprocket. If you have any ideas why the exhaust sprocket is thicker and not just a regular gear, please enlighten me! The more ya know :)
I know this is well late I hope you can reply, I know you had to have the machine shop modify the block for the k24a on the newer Z block . So would you need to modify the k24a block for the newer k24 Z style head? Or would the head have to be modified? Or would no changes need to be made?

Yeah the k24a2 and k20z3 head is a pretty bad ass set up. Tune is the biggest factor when running it. Got to upgrade the oil pump at that time or the k20 head is basically useless because the k24 doesn't have the reving ability without it. so there would be really no sense in pairing it with a K20 head unless you upgraded the pump as well. Even then you can't get the full potential out of the k20z3 head , you have to be careful of the VTC degree.
@@corbinyoung5320 the VTC is the gear on the intake cam. It's also known as a cam phaser. If you're not running the right degree you could possibly make contact between the valve and pistons
Good info! The crank pos sensor difference is pretty reminiscent of the Honda H series DOHC motors, on those, the usdm obd2 h22a4’s use a similar setup except the crank pos sensor bolts onto the oil pump which is bolted to the front bottom of the block. On jdm h22/23 they use a crank angle sensor which is in the middle of the back of the block reading the crank between cyl 2 and 3. For that reason any jdm h series swap will likely require transfer of a usdm oil pump for the CKP sensor
Love these videos! Keep up the good work 😉 question, curious if you had considered doing a J - series swap for your Accord? I am investigating a J35A8 swap for a TL
Are you planning on porting the K24a2 head? I know one of the main reasons people generally like to get the a2/z1 heads is because of the flow capabilities vs the K24a2.
Exactly the build I want to do. I have a 09 tsx with the k24z3. I have a spare engine at my shop. All I need to do is source a k24a2 head which isn’t a big deal down here in so Florida. Looking forward on this build 🙌🏼
The right tuner is the most important part. Im going 4 years on the same tune same/headgasket/build. 400 plus whp on 91 octane. Daily driven/tow vehicle.
Some great info here....just about to pick up my first JDM vehicle... 2007 Odyssey Absolute with a K24A. Planning on Hondata and supercharging. Just not sure what header I can run on this thing.
Damn, wish I had your knowledge and skill bro. I have a 2009 Honda Accord/Acura TSX with the same K24Z3 Engine. And I wish to make more power - 250-280 HP , something like that and to be able to smoke some cocky friends with their 3.0 turbo diesel german garbage cars.
YESSSS I love it!!! Well in theory you can get that done with using OEM parts only, but a head swap will be almost necessary. You may be able to use your Z3 head with some upgrades like cams and valves, but the dual VTEC paired with the other things mentioned in this video WITH higher compression pistons will allow me to get that... fingers crossed
Finally, someone cleared up the difference between the K24 blocks! It's a good thing you're staying away from the "Frankenstein" setup. The high compression is not worth the headache of oil consumption, or blown valve seals. I learned my lesson with a B20-VTC.
@@CLozs it's possible! Heres a dude who builds amazing engines. 330hp NA! K24 with K20 head Frankenstein build! ua-cam.com/video/9Wc_q_4blyw/v-deo.html
Dude, THANK YOU! I am considering a Short Block replacement for my K20A2. Either K24 or another K20. (2002 RSX Type S.). It's lost compression from 190 down to 110-120. I feel like it's more cost effective to simply replace the short block with a new one. Go from there. I had Bolt Ons on it previously, and never got to tune it. This time around, 10 years later, I'm going to do it right and finish what I started.
Someone should make an inline 6 based on the K-series. Imagine an aftermarket replacement for 2J's and RB's and Honda based. 3.6L, smoother, still high rpm.
We're there any other modifications nessacary to mate the a2 head to the z3 block. And do all a2 heads have the exhaust lobes, or only the 3rd revision
love the fact you going N/A boosting is nothign but headaches and pains in the ass...constant boost leaks and tuning bullcrap along with loss of reliability, more shit to break. N/A ALL THE WAY EVERY DAY!
Boosting is only a headache if u don’t do it the right way. It’s Not about only slapping a turbo without all supporting mods to engine and fuel management Cheap Build= Cheap Results
Got an RSX 2003 and already have a hole K24a2 but I got to do pistonrings. Was looking to se if I can bolt on a K20a2 head and thats all I need.? Already Have RBC and 70mmTb/Skunk2 short Header
And on the tsx k24a2 there no vtc on both only on intake,,the reason for the thicker vtc cam gear on the EX side is cause 3 lobe cam vs the single lobe on the k24z3..the thicker one where is more for balancing the cam gear on the single lobe is lighter ..
Felix Fïxitfelïx, agreed. I don’t think any K24 engines came with dual VTC from the factory. Only 10th gen Civics have that. Regardless, very interested to see how the dual VTCs would be used. Stock ECU for sure wouldn’t know how to control the exhaust VTC.
If I have an engine from a 2007 Honda Accord 2.4L I believe it’s the K24a bottom and top end but would I have to check if the cams have both v-tec or where would be a good start on an N/A build?
Hi, 2009 acura tsx intake cam actuator question. Is there aftermarket actuator is better than oem? If it is who makes the better one? Oem little expensive and also timing kits too. Please let me know. Thankyou.
I have a k24 z3 in an off-road race buggy. I also have a spare k24 a3 engine. Would I gain power putting the a3 head on the z3 block along with some aftermarket a3 cams ? I don’t want to have to modify mounts etc to fit the a3 engine
Hey brother thanks for the video. I hope you answer my question. So I have a 2004 Honda accord with k24a4 engine but the cylinder head is the more basic one . I want want the k24a2 head with both intake and exhaust vtech what do you recommend?
you should be able to use the old style crank gear sensor and timing cover on a later year block, I have not tried it, but dont see why it would not work, i guess they changed to the 60 tooth in 07-08+ or maybe later then that. probably since the 60 tooth tone ring sensor is in the upper removable oil pan you probably swap the later model crank and oil pan to a older model block as well.
i thought the hosepower different between k20 and k24 is due to engine speed, and maximum safe engine speed is related to the piston travel distance. k24 being longer stroke, its piston will always travel longer distance compare to k20 at the given engine speed.
Not sure if you'll respond but, I have questions. 2009 2.4 Accord, detonation on cylinder one. Head swap with 2004 2.4 CRV? I should mostly fine right? Ugh sheesh, got the CRV K24 on a stand, and the Accord's K24 still inside, mostly disassembled. Lots of work, hope it works lol
I pretty much have 2 builds going on. My first one is a k24a1 CR-V bottom end with a K20z3 head with the head being completed except for the cams and the second build is a k24a2 TSX engine getting ready to tear down the block
which K24 is used with the Earth dreams technology 2016+ Acoord/CRV? It has a reverse head with the built in exhaust manifold pointed towards the radiator and the intake by the firewall. I can't find the engine code no matter where I look.
Great clear and precise explanations of the differences between the different K series. I have both an 04 and an 09TSX and was wondering what the difference was between the 2 engines. The 09 is definitely easier and cleaner to do an oil change on thats for sure.
I just picked up an 8th gen accord k24 auto. Wanting to know can I manual swap a z7 manual 9th gen si civic trans to use with my manual swap or does it have to be a 5spd trans??
I have a k24z1 in my 07 crv. And my head gasket blow because i was driving it overheating for like 30 minutes. I would like to know if my head got warped and if the k24a got the same plugs as the z1

The crank pos sensor difference is pretty reminiscent of the Honda H series DOHC motors, on those, the usdm obd2 h22a4’s use a similar setup except the crank pos sensor bolts onto the oil pump which is bolted to the front bottom of the block. On jdm h22/23 they use a crank angle sensor which is in the middle of the back of the block reading the crank between cyl 2 and 3. For that reason any jdm h series swap will likely require transfer of a usdm oil pump for the CKP sensor
Love these videos! Keep up the good work 😉 question, curious if you had considered doing a J - series swap for your Accord? I am investigating a J35A8 swap for a TL
J series share same mount points. People j37 swap 8th gen accords and make more power with a stock tune.
This cleared so many things. New to Honda and their engines. I feel far more confident in doing my engine swap
Happy to help Terry! Good luck with your swap
Are you planning on porting the K24a2 head? I know one of the main reasons people generally like to get the a2/z1 heads is because of the flow capabilities vs the K24a2.
Yes I will be. Stock, it isn't the BEST flowing head, however with it ported, it flows very well
This is alot of information. I will have to save this video and watch many times to absorb this. Thank you for sharing your knowledge ❤
All the info I needed, thanks man.
Exactly the build I want to do. I have a 09 tsx with the k24z3. I have a spare engine at my shop. All I need to do is source a k24a2 head which isn’t a big deal down here in so Florida. Looking forward on this build 🙌🏼
love the detail in your videos keep the vids coming!
Thanks Sammy! I appreciate it 👊
Hi Milan, is there a video of the build process? I wanted to see what all you did to assemble the components. Thanks, great stuff!
I think you’re gonna need some drag cartel cams if you want 300 or at least some higher compression like 12.1
Yes you are right!
Which is the best series a and z ?
There is no headaches when boosting A honda.
SI RICKO finding the right tuner to make it last and not cheap out on parts if you’re boosting stock? Correct me if I’m wrong
@@itsreallytheo it's also not cheap to "build" an NA engine then get it tuned.
Typically it's only 200$ more to tune on boost vs NA. IF THAT
The right tuner is the most important part. Im going 4 years on the same tune same/headgasket/build. 400 plus whp on 91 octane. Daily driven/tow vehicle.
TheoMusic978 you can boost a k24 up to 500hp on stock internals with no issues. After that you will start getting problems.
Na is a waste
This is going to be super fun! Euro chassis with Honda Engine=rev all day long and bullet proof!
2000 si didn't come with a Kseries.
Josh Thompson early 2000’s he said and yes ep3 hatchback k20a3 aswell as base acura rsx
Honda introduced the 2001 Honda CTR in the year 2000 and was available to the public BEFORE the year 2001.
Kool I heard 2000 si which didn't.
The em1 si had a b16a2
The 2000 si It came with a b16 in us market
Verrrry good boy!!!! I’m subbed. Great job! Please keep this up with the k series demographic it’s a very big n growing community.
I have a k24z7 in my si does anyone know how much HP i can get out of a build engine ?
I've seen guys straight up switch heads and nothing else, and get to 260whp after tuning.
milanmastracci maybe with full bolt ons too haha
how much money you got? skys the limit if you got deep pockets
This is my dream build.
N/A stroked k24 (k27)
400-500hp fully gutted eg hatch on race gas/e85 😍
Looks like someone has heard of the company 4P 😏
400-500 na? Nah pipe dream.
have the government closed your schools too ? if so i am guessing there will be a few more videos coming soon :)
Yes they've closed, but assignments and take home exams are a thing! I'm going to be done school as of March 30th
Awesome vid and loved the intro. Correction about the K20Z, the Z1 was introduced in 2005 on the RSX-S
also, the K20Z3 from the 2006 Si lost the manual throttle cable for dbw, gained RBC intake manifold and balance shaft that robbed high rpm HP.
grade A++ content !!!!
Some great info here....just about to pick up my first JDM vehicle... 2007 Odyssey Absolute with a K24A. Planning on Hondata and supercharging.
Just not sure what header I can run on this thing.
Swapping k24 into my B12 Sentra
I like the way he explains the difference in performance,I'd rather go all motor if I do a K24 setup,thank you for your Knowledge.
Damn, wish I had your knowledge and skill bro. I have a 2009 Honda Accord/Acura TSX with the same K24Z3 Engine. And I wish to make more power - 250-280 HP , something like that and to be able to smoke some cocky friends with their 3.0 turbo diesel german garbage cars.
YESSSS I love it!!! Well in theory you can get that done with using OEM parts only, but a head swap will be almost necessary. You may be able to use your Z3 head with some upgrades like cams and valves, but the dual VTEC paired with the other things mentioned in this video WITH higher compression pistons will allow me to get that... fingers crossed
Искрен Апостолов should of got a CL9
sure sure, boi, tell me when you get at least 260crankHP on 98oct/93oct(us) with your build!
Iskren, menshe slushaj takix mechtatelej i divannyx tiunerov;p

Finally, someone cleared up the difference between the K24 blocks! It's a good thing you're staying away from the "Frankenstein" setup. The high compression is not worth the headache of oil consumption, or blown valve seals. I learned my lesson with a B20-VTC.
I'm going with a higher compression piston than what was in my accord. Stock for me is 10.5:1
I've been running a tuned and bolted frank for five years now. Not one single issue.
@@lindaover9764 you're an exception, not the rule. That's why you always see B20 vtech swapped cars for sale left and right, shortly after the swap.
@@DIABOLICOHAVOC I haven't heard any issues mating a k20 head to a k24 block. That's what I'm running
@@lindaover9764 oh, I was referring to the B20 VTech. I don't have any experience with the k series Frankenstein.
300whp na would be insane
Luis Ayala i’ve nvr seen tht from a 4 banger that does not have forced induction
@@CLozs it's possible! Heres a dude who builds amazing engines. 330hp NA! K24 with K20 head Frankenstein build! ua-cam.com/video/9Wc_q_4blyw/v-deo.html
4piston racing got 500hp to the wheels NA a few years back on a k24 platform. Granted, there was nothing factory left on it, still insane nonetheless
@@CLozs theres thousands of them driving around. A 300whp k24 isnt hard its simple build
Phar2Rekliss sick ass 8th gen but that’s probably way more money then building it with forced induction
Very simple and concise video that explains a lot of information. Great job sir!
I made 314 all motor hp on pump gas and then 340hp on M5 fuel. I have a k24A rbb bottom end and a k20z1 head.
That is sick my man I'm gonna swap one of these bad boys into my B12 sentra. How much did your build cost you?
@@erendyalatorre7785 7k
Dude, THANK YOU!
I am considering a Short Block replacement for my K20A2. Either K24 or another K20. (2002 RSX Type S.). It's lost compression from 190 down to 110-120. I feel like it's more cost effective to simply replace the short block with a new one. Go from there. I had Bolt Ons on it previously, and never got to tune it. This time around, 10 years later, I'm going to do it right and finish what I started.
K24A4: "What about me guys?" :(
I have the K20C2, there is absolutely NO aftermarket support for my engine :(
Nice video , just bought a new k24a2 for my 04 tsx so I’m excited for ur build x)
Someone should make an inline 6 based on the K-series. Imagine an aftermarket replacement for 2J's and RB's and Honda based. 3.6L, smoother, still high rpm.
Love my k24a8 (176k miles), just put on the 06'+ TSX intake manifold highly recommend 👌runs like a top.
I'd like to buy a motor for ²⁰⁰ dollars
You ain't lyin shit they are all closer to 1k nowadays
We're there any other modifications nessacary to mate the a2 head to the z3 block. And do all a2 heads have the exhaust lobes, or only the 3rd revision
Never seen a K come in any odyssey in the states. That’s just silly!
I never said in the states it was available, just like how the JDM CTR was available for purchase in the year 2000.
Odyssey in Asian market use K , they are very different car to our Odysseys.
Wait, What You Guys Get In The States?
@@ahrred3127 J35's in our Odysseys.
Ryan Mahon they are in the Honda Odyssey Absolute from Japan
Great video. Can you answer this question?? I bought a K24A, no number after the A. Do you know what car this came out of?? Thank you!
That sounds like a JDM engine, not from North America.
love the fact you going N/A boosting is nothign but headaches and pains in the ass...constant boost leaks and tuning bullcrap along with loss of reliability, more shit to break. N/A ALL THE WAY EVERY DAY!
Boosting is only a headache if u don’t do it the right way. It’s Not about only slapping a turbo without all supporting mods to engine and fuel management
Cheap Build= Cheap Results
Got an RSX 2003 and already have a hole K24a2 but I got to do pistonrings. Was looking to se if I can bolt on a K20a2 head and thats all I need.? Already Have RBC and 70mmTb/Skunk2 short Header
How can you compare a boosted almighty Honda to a Mini. Shame on you and your soul.
First time seeing the channel, this is EPIC!! Keep up the awesome work and content, great recommendation!
Hey dude i also have a 2009 accord! Mine currently has a k24z3, is it worth swapping the head or should i swap in a different k24?
And on the tsx k24a2 there no vtc on both only on intake,,the reason for the thicker vtc cam gear on the EX side is cause 3 lobe cam vs the single lobe on the k24z3..the thicker one where is more for balancing the cam gear on the single lobe is lighter ..
Felix Fïxitfelïx, agreed. I don’t think any K24 engines came with dual VTC from the factory. Only 10th gen Civics have that. Regardless, very interested to see how the dual VTCs would be used. Stock ECU for sure wouldn’t know how to control the exhaust VTC.
If I have an engine from a 2007 Honda Accord 2.4L I believe it’s the K24a bottom and top end but would I have to check if the cams have both v-tec or where would be a good start on an N/A build?
Hi, 2009 acura tsx intake cam actuator question. Is there aftermarket actuator is better than oem? If it is who makes the better one? Oem little expensive and also timing kits too. Please let me know. Thankyou.
I have k24z7 want to know if keeping the original head but changing all the components on the head well bring hp
I have a k24 z3 in an off-road race buggy. I also have a spare k24 a3 engine. Would I gain power putting the a3 head on the z3 block along with some aftermarket a3 cams ? I don’t want to have to modify mounts etc to fit the a3 engine
Glad you are keeping it simple and going NA this time around.
Yeah me too! I'm hoping to keep it as reliable as its been for the past 235k kilometres..
Hey brother thanks for the video. I hope you answer my question. So I have a 2004 Honda accord with k24a4 engine but the cylinder head is the more basic one . I want want the k24a2 head with both intake and exhaust vtech what do you recommend?
you should be able to use the old style crank gear sensor and timing cover on a later year block, I have not tried it, but dont see why it would not work, i guess they changed to the 60 tooth in 07-08+ or maybe later then that. probably since the 60 tooth tone ring sensor is in the upper removable oil pan you probably swap the later model crank and oil pan to a older model block as well.
i thought the hosepower different between k20 and k24 is due to engine speed, and maximum safe engine speed is related to the piston travel distance. k24 being longer stroke, its piston will always travel longer distance compare to k20 at the given engine speed.
Cool video.... appreciated the work to compair. Mention the 50 degree cam sprocket the gives the k24 a jolt of Hp... if you know about it...
NA builds are life, you just earned a sub.
So what would be necessary to make the block fit for the crank sensor to work
Not sure if you'll respond but, I have questions.
2009 2.4 Accord, detonation on cylinder one.
Head swap with 2004 2.4 CRV? I should mostly fine right? Ugh sheesh, got the CRV K24 on a stand, and the Accord's K24 still inside, mostly disassembled.
Lots of work, hope it works lol
I pretty much have 2 builds going on. My first one is a k24a1 CR-V bottom end with a K20z3 head with the head being completed except for the cams and the second build is a k24a2 TSX engine getting ready to tear down the block
which K24 is used with the Earth dreams technology 2016+ Acoord/CRV? It has a reverse head with the built in exhaust manifold pointed towards the radiator and the intake by the firewall. I can't find the engine code no matter where I look.
Done rebuilt k24bottom end! K20head will be nice. +Powdercoat red vault cover ... will look sick.
K24a block rbc2 head how is the performance
The research and work done here is impressive. The explanation is great. I don’t have a Honda but like your video. Thanks
Awesome, thank you!
The engine wasn’t introduced until 2001
So the only thing needed to run for example a k24z7 bottom with a k24a2 top is the coolant port machining to match the head gasket for the k24a2?
Pretty much, yes.
Because I have a 2010 LX-P k24z2 4 accord and I want to change the handfold because I want more power but I don't know if it's the same as the k24a2
Great clear and precise explanations of the differences between the different K series. I have both an 04 and an 09TSX and was wondering what the difference was between the 2 engines. The 09 is definitely easier and cleaner to do an oil change on thats for sure.
Hawks Fan the cams on the 04 tsx is better than the 09 , it got RBB head when the 09 doesn’t.
Is a k24z1 a good block to build? Thinking about putting one in an Rx7 in the future.
I just picked up an 8th gen accord k24 auto. Wanting to know can I manual swap a z7 manual 9th gen si civic trans to use with my manual swap or does it have to be a 5spd trans??
I have a k24z1 in my 07 crv. And my head gasket blow because i was driving it overheating for like 30 minutes. I would like to know if my head got warped and if the k24a got the same plugs as the z1
