Do valve springs from a k20a2 work with a k24z7
Cylinder Heads : 1:10
K24 Blocks : 4:15
Type S Oil Pump 9:01
Needed Parts For Swap 10:20
Misc /Intake/Header 12:43
Thanks for the great info by a true Honda Master! 👌👍👍👍
Bigger is not always better, to big could hinder flow for horsepower. Check out engine masters on motor trend they to explain things although they do use V8’s but the explanation is the same on any motor
I agree that it's a balance of flow and velocity to match the block and intake manifold but I think Mike is trying to point out that ultimately if you restrict your flow you loose horsepower and if your going for 1000hp you will need the max flow available
💪
Transmission??
The highest output "OEM" build is based on the following:
06-08 K24A2 block
K20A2 Head
06-08 TSX cams
RSX Type-S cam gear
Type-S oil pump
Type-S oil pan
Hope this helps anyone looking for direct answers like I was.
Is k24a3 block same as k24a2?
@@RealLeskot its pretty identical but has about 8lbs more torque
@@6speedvtec789i thought the k20z3 was better
@okboomer250 they're close. The A2 has a fraction more power, but mainly it's used because it has the highest flowing head in CFM for a US K series
I like that set up too.. but i'm going with stock k24a2 with type S oil pump on boost.... maybe throw in the z3 head
These were the spoon engine's Hector was going to run in his 3 Honda Civic at race war.
Don't let that distract you from the fact that hes gonna be running 3 t66 turbos with NOS and motec exhausts!
That is what he said when he came into Harry's.
How to do the timing

Wow this is a golden video for the K series community. Shoutout all my DC5s tho!
Hoo yah dc5
DC5 for the win ... who's looking forward to the Integra type R ??
Dc5 gang 💯💯🥇
I like the fact that you shared the information all the part numbers he didn’t tell us to go look for it and put it right there in front and appreciate the speedy secret about the oils quarter what works and what doesn’t, good job
Wow bro, you are a king for this video. I’ve been hesitant to know what engine I’ve been wanting to swap and you answered all my prayers. This video is a holy grail. Shoutout and kudos to you. You are a blessing to the car community 🙌🏼💯
i dont know how to look up any of these parts, when i search many different things come up, i have no idea where to start
@@donjonson6407 if you can't search part numbers then i assume this job is way to much for you. Best to find a race shop who offer these services and pay them to acquire and assemble the motor for you.
@@Philthese93 sweet thanks man
My personal tip is when it comes to headers if you’re not going with a compression higher then 12.5:1 then don’t do a big tube 4-1 header. All stock block K’s need a big tube 4-2-1 header preferably like a TRI-Y design header because they flow very well and it keeps carrying the power range up top instead of falling down like 4-1 headers tend to do. Yes 4-1 headers will makes more power but they suffer up top with stock compression K’s and it’s pointless to have a lot of power if you can’t even deliver it right. I’ve come to this realization after seeing the dyno graphs on many many K cars my tuner has messed with and feeling it myself on my personal car when I made the change since I’m on a stock block 24 👍
I agree with you thr the question is how much ho can you get from that build without raising the Cp 12.5:1 or higher because you gonna spend a lot of money.
I know there’s a lot of information here and you don’t want to overwhelm the listeners, but talking about cams would also be good to note, such as the most aggressive oem cams (best bang for the buck is ‘06 tsx cam. And talk about a couple after market cams. Also the 50 degree cam gear/sensor
I saw in another channel that aftermarket cams can cause issues with the chain tensioners. Boosted engines really don't need any cams other than stock to get up to 800hp.
You are correct. Cams don't matter as much when force inducted. It's going in one way or another.
I'm a newbie to engine building, and I have watched many videos but your technical knowledge and explanation about each component needed in a building a k24 is on another level bro. Excellent content. A great help in my arsenal now.
Are you a certified mechanic who just started engine building? I’m tryin to do the same but I have no clue where to start. Except basics.
@@JDMRooqui no my friend, I'm mechanically minded and am doing it as I learn from d more experienced.
I'm more of a visual type guy, so this vid presentation is nice.
Sick garage too btw 👍
This video is pure gold. You’re spoiling the new generation and it’s kinda nice
Wonderful, nice to see all the basic casting variants explained in a single video. It's all common knowledge, and it's all been around for a decade, but damned if I never saw it all covered in one place so well. Thanks.
Personally didn’t know a lot of this, not common knowledge. I still don’t know how to churn butter and that’s been around for a while
1 7/8 diameter on the header on k series is a must for all motor
very informative. thanks for providing this information in a very simply way. searching for all this on the internet can be a hassle and kind of confusing. having a video explaining which parts to buy to build a k24 makes it some much easier. cant wait to see you engine finish being built and in your car.
Been waiting on this for a long time. Thank you
You should have talked about stock cam options for those who don’t want to break tensioners with aftermarket cams. Tsk 06-08 are the best but I’ve seen some interesting mix and match depending on which style of head you are running because the intake only vtec heads have a lot of potential and actually work with a turbo very well without vtec killer
This is a great video brother !! Made everything very clear !!
My friend gifted me a k24a4 block for free . My plan is to rebuild the entire block for all motor set up and slap a 4piston head
Btw you have to use the CRV head gasket if running the PRB head (type-S). Use TSX head gasket if using RBC/RBB/RSP cylinder heads, regardless of which k24a block you have
why is this necessary? i bought a k24a2 motor and i plan on putting the block in my type s (k20/k24) so i’d rather save myself from breaking something 😅
@@wherescvrlos because the different cylinder head castings have different coolant passages
I watched this video before but now that I'm thinking about swapping my del sol this video was really helpful
Damn man this video is so good. I bought an 06 dc5 with stock k20z1 long block and rbc intake manifold and was looking for info on swapping k24 short block but have no knowledge of the k series compatibility. You pretty much answered any question there is good stuff 👍
Well when I get done, I can use this information to get into these Honda motors.
Very professional video. Thanks. What is the best way to plug the oil jet when using the K20 oil pump on K24A2?
I picked up a k24a8 for $70 from offerup. im going forged so it was a no brainer for me. thanks for the info
This video helped me finally start my build
Thank you so much for the video, its a great reference that's super useful!
Nooooooo WAaAAAAAAY! Genius🤘🏽🤘🏽🤘🏽✊🏽✊🏽✊🏽✊🏽✊🏽✊🏽
dense with information, this is a quality video
T-Minus every CRV 02-06 gone off eBay
Bro no joke 😭
I'm actually planning on doing a k20/k24 build with my 8th gen civic si but I'm gonna keep it simple with the k20z3 heads and the k24a2 block but I'm definitely going to port and cut my rbc manifold to fit a k tuned 80mm throttle body
Have you done it yet?? If so lemme get in contact with you. I got questions
@@liamhenry3046 no still didn't started yet probably this winter
Thank you Diymike great information and presentation I’m surely gonna go back to this video on my next engine build and swap
It's actually ANY RSX oil pump. The A3 in the base RSX also uses the PRB oil pump same as the Type S, where as the A3 in the EP3 does not. Only really useful info if you happen to find one at the junkyard that you wanna pull the parts from for that cheap.
Very informative! I like the idea of centralizing all the scattered information.
I'm thinking about building a k24a4 for boost with forged pistons and rods. Looking to make around 400 whp reliably. Would I be better off saving the money and keeping the tsx head or going ahead and dropping the money for a K20 head so that I don't regret it later?
Respect Modified I would keep the tsx head if you buy a complete long block. With that power want/level you should be fine unless you want a better head. But if you piece everything together then go with what you can get the best deal on to save some money for other areas.
@@AustinSmith-sx4uk Good to hear. I appreciate the reply
RBC Head also comes with K20A JDM
Great video!! my question : which manual transmission is best suited to this swap? Thank you very much
you can use.... 2002-2005 EP3/RSX 5 speed... RSX TYPE S 6 speed... or 2006-2011 CIVIC SI... the 06-11 civic si is probably best because it comes with factory LSD.
I fuckin swear, if someone ask one more thing about the k20/k24 Frankenstein build... I will flip out!!! I’ll just send them this link.... this truly is the ultimate guide.
The 06-08 K24a2 head is EXTREMELY underrated by most.
How is it better then 04 tsx
cheers dude, we need extra info concerning Euro as well as US for cross over use!
I have 71 240z and it boosted but im on my 14th transmission and I've always wanted to swap a k24 but I'd have to put a ton of money into a good transmission. I really want is like a six-speed sequential.
Hey man I have a few question if you have time! I really want to keep my honda around and i'm going to rebuild it one day and can't find the exact answers I need but you've answered most in just one vid!
Damn mike, thank you for all that information 🙏
Does the head of a k20a2, k20z3 or k24a2 fit on k24z7/k24z3 bottom end and does the k20 oil pump bolt right up ?
I want to know too
Hey @Diymike I love how you explain things… I wanted to swap my 04 Honda Accord Ex Sedan, and put a k20 engine from a Acura.. and work on the engine from the outside then install it to the accord… the only problem dude is I want to do this to an automatic….
People telling me add a new intake manifold injectors and also new exhaust manifold and exhaust system and so more other things to make more hp… I wanted to gain more hp but I also know I have to get a Hondata or a K tuner … I wanted to ask you what’s the best way to do it with my AUTOMATIC… I don’t want insane hp but a good number
Thinking of do safe mild build. Around 240hp.
Thats bro, for helping all of us with this information👍
What cams would you use in a ppa vtec killer setup for NA power?
Skunk2 bmf camshaft 1-6
TSX K24A DOHC RBB V TEC Engine also can i use the PRB 2002-2006 RSX TYPE S Head on a 95 HONDA PRELUDE THANKS
One combo i saw not long ago was a base rsx k20 block with a crv k24a1 head with 05 accord rockers and aftermarket cams made 280whp they were going for cheapest 300hp all motor car
@devinej8411 must has been on race fuel.. ain’t no way it making that
What about the k24z7 block is that a good block
Terrance Herman stock block Z7’s are good for about 400hp before blowing up.
Great info bro thanks. Keep I’ll the great work
Dam I enjoyed the video Mike. I learned so much from this video. I’m still stuck on the b’s. Also you didn’t mentioned the transmissions. Where to begin on that?
You wanna do an rsx or civic si 6 spd manual
Great Info man Ty ... your electric water pump should not be mounted on the block (Vibrations)
Thank you for this video! I want to go straight K20 motor and transmission swap in my Del sol, could you possibly make a video on what’s needed to do a straight swap including 6 speed?
Chrispena86 gonna have to do a lot cutting and welding
Very easy man just need all your parts if want me to explain hit me up.ig.p72jdm
Thanks for the info Mike! Your the best!👍🏽
May God bless you with abundance of joy and moneyyy 🙏🏻
A K24w9 head you can bolt a turbo directly to the head and have no lag. At least my 2016 CRV AWD CVT. 3768 is more than enough turbo for me. And a hondata flash tune 12.4 air fuel. It's just a fun family car racing it will probably blow it up
Awesome bit of info for the new builder. Which engine would you reccomend for a first time conversion...best bang for buck. Here in the U.K? much appreciated 👍🏾
Just got myself a 2004 crv awd swap got it all ripped out now standing here looking at my eg scratching my head
How about the K24Z7 block? Same thing as the K24Z1?
what about pistons ? for high revving and high compression ratio ?
Can you make a video talking about ITBS ???
I would like to hear your opinions on them with the rsp head
No mention of the JDM RBC head/block from the EuroR.
Nice mike so great! Greetings from germany!!!!
In your opinion . Is it worth while to do the head swap on the TSX k24a2 block ? For money spent would you notice the difference in HP gains ? Thank you very much .
there was a dyno of a k24a2 stock... then one with a RSP headswap.... it made 12-15hp more.

Great video!
What up TH-cam Troy here again to ask questions on your video with all the answers..
2007 Element SC (5speed)
Just want to get a good 350hp or so what’s the best plan of attack to reach suck goals?
Is the the displacement still 2.4? Or does it drop a little due to the compression increase from the k20 head
Awesome video, thank you for posting.
Thanks for the video. If you could add some info about oem cams that would be awesome. Enjoy the swap. 💪
The 02 04 type s is a k20a2 and the 05 06 have a k20z1 they have the same heads?? you guys and boosted boiz have inspired me to build my 05 type s I'm using a k20z1 head with a k24a2 block I'm using the z1 harness what's the best engine management I can use I have a 1320 sidewinder got it cheap so I bought it and found a cheap holset h1c turbo so I'm using that with ebay intercooler ebay tial replica bov and waste gate, I've customized my fuel rail for return and also I'm getting a hondata 4 port boost solenoid I will be using my type s oil pump i never turboed an engine before besides helping my buddy with his rb25det g35 if u can point me to the right direction I'll appreciate it thanks guys
Same head but different Cams .. the 2005-2006 rsx type s is rated at more HP than a 2002-2004
@@diymike what engine managment u reccomend me using for my build
I would recommend kpro.
so whats the best for all moter , stock block and head if you were going to get the head ported
What ever happened to that jb weld filled block ya was doin?
I am planning to swap K20 with K24. Which assembly parts will be replaced and which K20 parts will keep running as it is? Blocks, Cyclinder head, Headers?
The reason I want to do this is to achieve same Horsepower and low-end torque as CL9 with Stock K24.
Can someone explain in detail?
What’s the final compression with a k24a2 block and k20a2 head?
Is the K24A2 not the same as a A3? I thought the earlier one was the same
If I use the k24 from the crv do I have to swap out the crankshaft or will I still be able to use the stock crv crankshaft?
but the crv doesn't have oil squirters ? whats your opinion ?
Regarding the center feed manifold; is it possible to flip them upside down and do an old fashioned hood scoop instead of fabricating one through the bumper?
What about the k24z7 block with type s head
So I'm that guy that picked up a super cheap k24a4. I do plan on putting a 8th gen si head on it and have heard about the piston interface to the k20 head. I always assumed there is an aftermarket solution as you mentioned but haven't dug too deep into it yet.....what are your recommendations for pistons and rods when using a k24a4? Fyi I plan to do NA initially, but want to build the internals to hold boosted power in the future.
a simple H beam Rod and aftermarket turbo pistons around 10.1 compression should do the trick. the sell pistons specifically for k20/k24 setups. you're looking to spend around 700-1000 for a simple piston and rod set up.
Can the cams and rocker assembly from a PRB (Type-S) head be installed in a PPA head? I am not sure if it will be less work for me but trying to figure out a way to use my RBB intake manifold with less cutting and welding. This is an amazing video! Thanks for putting it together!
Does anyone else notice that booming sound in the background? Was barely noticeable when I stopped listening through speakers. Reminds me of when I lived near Camp Pendleton.
Thanks for the great info Mike! Do you know if the k24a1 lower girdle will fit on a k24a2/a3 ?
Lots of great info, THX!
So will the hybrid racing harness work on this motor they say it dose not work on k24 but because this has a k20 head it will right
Would you build head like this for my k24a3 please?
Mike, what a great video man, been looking for this info for a long time, so thank you very much. For all of us 9th gen Civic Si Owners, with the “unhappy” k24z7 engine. It’s the same build that for the k24z1? I mean, relocate oil filter, type s oil pump, block oil jet, change pistons, use k24 head gasket ?. Aaand... for the engine management, is the stock ecu with Hondata Flashpro or Ktuner enough ? I’m thinking our engine comes with intake vtec only (yeah, so sad!)
What do you think about a k24a 1 or should I put a k24 a2 head on it
What cause my k24 a2 to be lazy and burning raw gas? After service and changing the computer also change wire loom the problem still exist. The mechanic said one of the cylinder psi lower the rest. What could cause that?
Just picked up a running k24a1 with 92k for 100 bucks!
Any recomendation oil brand and viscosity for k20 k24 allmotor std king race bearings near 300hp for daily use??
I'm sure there's a few that might run Amsoil, but for everyone else including me, likes running to their nearest walmart to grab quality fullsyn oil off the shelf is convenient as well as the price i.e. Mobil1 or Pennzoil.
5W-30 is a go to for anyone that lives in the rust belt
bobtheoilguy.com
@@Kawaii_Life. Thanks,i use mobil 1 too,think to switch to Motul or Amsoil
you mentioned in the video that A4 and Z blocks will need aftermarket piston rod combo so they do not interfere with the k20 head, but it was unclear if that is also the case on the A1 CRV block. can the head be installed to the stock short block without any interference?
Anything about oil pan?
Any recommendations on bearings and gaskets???? I know that there are some that are bad and don’t hold up but I want to know the top brand or best bang for your buck
Would you know a good place to search for the K20A head. I only see the k20A2 all places
Im gonna rebuild my k24a1 in my 2004 crv do you know who got the best stock rebuild kit out there?
Hello, I have a 2012 civic si. I wanna build an engine and put it in this car. I am just wondering because 9th gens does not have downpipe. I wanna do a k20 headswap so meaning I'm gonna need a different header. Should it fit, like header to exhaust wise for 9th gens?
Xcessive makes the other one yes. Best bang for the buck because it's $580 Mike.
Couple days back i got a 03 k24 accord manual and i am having a burning oil problem got under the car there's absolutely no leak at all clean as it can be but still cant fin the problem
What about k24z2? I plan on putting a k24a2 head from a tsx on it. I know ill need a machine shop to modify one of the cooling ports. How do you get the cars ecu to accept the head change?
