As kswap gets more and more popular, so does the demand for JDM K24a. Because this engine is not originally from the states, it has a waterpump housing that is not compatible with what we have here. So over time, to make it compatible with our market, you had to swap over a USDM K20/K24 waterpump housing to make it work. But all that has change now. Hybridracing racing offers a special idler pulley that allows you to keep your JDM waterpump housing. Giving you more options instead of swapping over to a USDM waterpump housing. Pros and Cons of this idler pulley. Is Convenient and cost-effective. Cons, if the JDM alternator or tensioner goes bad, it would be very hard to replace since it is not a part we typically sell here in the states.

I swapped in an 05 Accord water pump housing on my RBB, seem to fit great.
Thank you for sharing this information 🙏 I was always curious but just went with what everyone else posted online while researching.
great to know!
2013 crv USA car has k24 engine blew. Can I put a jam variant to fit with no probs its auto
Yes you can, just get a k24z varirent with the r40 head. You might have to swap over sensor and what not but is possible
I have a 2013 civic si and it has a k24z7 if it was to go out I would definitely go with a jdm k24z or a k24a.
I own a 5 speed 2005 Honda accord coupe would I need to change anything if I’m doing this swap ???
You're going to have to get your ecu reflash and see what is compatible with the k24a, like plugs and sensors.
What’s the difference between rbb2 rbb3 and rbb4
Year it was made rbb3 rbb4 are 06 to 08
even the JDM water pump got 2 types of outlet, straight facing down and angled
The 07-08 ones are the same when JDM. Only different in USDM TSX type-s iirc.
Good information here thank you.
You can use idler pulley and alternator from 2009-2014 K24Z3 TSX on JDM K24A engine, don't need to buy pricey idler pulley.
I try mocking a k24z3 idler pulley on to the jdm waterpump housing, and it did not fit.
03-07 accord water pump housing will fit as well
Cast iron piston sleeves I believe on k24a jdm
👍💪🤝🔥💯
Im running K24a2 with K20 oil cooler, water pump and housing, with RSX belt tensioner, power steering pump, k20z1 alternator, on a K20a2 crank pulley and non-ac belt. With dual height Hasport mounts on lowest setting none of it touches the hood.
What intake manifold you running?
@@Almostboosted 04-05 TSX intake manifold with 03 Accord throttle body.
How much hp did you make with that set up?
Hey bro is it possible to slap a k24a rbb 3 lobe vtec. On a 9gem civic si sedan my motor is done.. I haven’t really seen them do that..
I'm not too sure, to be honest. I have heard that the k24z block has different water port vs. the k24a cylinder head. I saw 4piston do it before. Is more common to swap a k20z3 head. I also seen jdm k24z.
Nice job on the video , I hv a k24a2 , out of an 05 Tsx , that I want to build a little and put in my 03 crv,5-speed. Information in crv k24 swaps is limited, but your video has plenty of good nuggets , keep up the good work.

My tsx came with k24a4 previous owner sold it to me with blown head gasket i boutght k24a imported i know i am going to need to change water pump housing what about the vetc sensor the k24a doenst have it and anything else that i need to change to make it run
On the back of the head you have the vtec valve. And you need to swap over the vtrc pressure switch, the k24a dosent have it.
will my 04 tsx ecu and harness work with the rbb?
If kswapiing on an older honda chassi, I'm not sure if with ktuner it could, but not kpro. If swapping the RBB to your 04 TSX yes.
Is the accord a type s motor
I believe the euro accord has two versions a type r k20a and a k24a rbb. In the states the accords have a different k24 and usdm tsx/accords only have a k24a2 no type s
What needed to swap this into an rsx type s and will i have clearance issues?
No issues, you would have good hood clearance, probably but the oil pan might sit a bit lower. Just swap over from the type s engine the: knock sensor, crank sensor and if you want which I recommend waterpump housing with oil cooler. Intake manifold with everything. And the intake vtc gear along with the whole oil pump kit. And make sure to get your ecu chipped with hondata.
I just bought a fa5 with a k24a rbb3 swap. The alternator is bad, it seems to have the usdm accessories. You had said either a base model rsx alternator or a 02-6 crv alternator should fit correct? Or can I get a k20z3 alternator. New to the k series. Coming from a j series
You can get the rsx base alternator, rsx type s, ep3, crv or tsx. Dont get the k20z3 .
@@Almostboosted awesome thanks man. I’ll go to the parts store and compare my current one with the tsx alternator
No problem boss
New sub! Getting more key info in case l get a K fever again!
Thank you for the support. I hope I'm able to help.
Should I just get the USDM k24a2? I heard the waterpump has to be configured and im looking to keep P/S
On the usdm tsx k24a2 the waterpump housing is fine is only on the jdm k24a. I seen jdm rbb k24a being sold for cheaper than k24a2. But if you could source a k24a2 cheaper with less mileage is good.
Thank you! Super dope content
Thank you, Erick. I appreciate it 🙏
I got an accord s type with 6 speed trans and a jdm k24a as soon as o start tearing it down ill be posting vids

u lie
Can i just take out my k24z3 an put a k24a in my 2008 honda accord coupe? Will every thing fit up
You tank try I know is been done with the 9th gen si k24a7. The problem is that your engine has sensor not in the same location than the k24a. For example like the crank sensor. On the k24z is located near the flywheel. And on the k24a is by the crank pulley.
Can***
K24z7***
@Almostboosted so thts the only problem I will have if I change the k24z3 to a k24a? Everything else will work
Double check your wired guide to make sure the pins are correct and get the ecu reflash. But double-check research to make sure.
I a k20z3 engine and looking to just swap over the head to a k24a would i be to transfer everything over?
Yes you can transfer everything
So I wouldn’t need to get the pulley or the crv mount? Or what would I have look out for?
You would need the crv post mount or you get can an aftermarket universal one. And by pulley I don't know what you mean. You can transfer everything or keep what you wish from the z3.
@@Almostboosted I was talking about the hybrid racing idler pulley but that’s only to keep the jdm water pump housing so my mistake
@@Almostboosted but other than the mount everything else should be good? Sorry my first time doing any of this haha
Thanks!
Thank you. I really appreciate the support 🙏
Any difference between the k24a and the k24a2?
To be honest they are very identical the k24a jdm Is the oversea version of the k24a2. Now the 06 to 08 k24a2 is a bit more aggressive vs the 04 to 05 k24a2. I'm sure it could be the same with the jdm k24a. I would just go with the jdm one just because it has way lower miles.
The only difference I see is cosmetic. Like difference overseas water pump housing, alternator and ac compressor, and power steering pump. You typically convert it with a usdm one.
@@Almostboosted oh ok gotcha I wanted to do a K frank (24/20) in my 8th gen si and here where I live this place called jdm place in Houston texas has the k24a for $800 for the long block.
@NightHawk_FA5 make sure it is an RBB head that's real true vtec.
@@Almostboosted RBB 2 head and 3 lobe vtec cams from what the guy said.
I asked from some people and they told me that i have to change engine camshaft or the ecu ???
There is no need to change the camshaft unless you want better ones. And ecu yes if you are swapping into older honda chassi you need a compatible ecu that has been flash or chipped.
What do you think about the k24a1 am thinking bout doing that in DC Integra I want it to be road trip Worthy
To be honest, I like k24a1 it has potential. But the k24a1 is not a true vtec k24, but for a budget, no power build is perfect.
Hello bro
I have installed the k24A rbb-2 engine on my honda Accord 2004. It worked great i am still using the engine, but i have one problem, and that's the car's The torque is weak
Car torque from 1000 to 2500 rpm ٠
Upgrade the clutch and flywheel to a stage 2 atleast.
Not sure what bolt ons you have but if you add bigger injectors and bigger throttle body feed it more are it should help gain more. Also look into a standalone like ktuner to solve you problems. Because I'm sure you had the k24a4 and now have a true vtec k24 in there and would need tunning.
Air***
so what’s better? rbb2 vs rbb3? i have rsx rbb2 on kpro w rbc intake mani and plm headers, custom exhaust. etc. basic bolt ons and my boy has fa5 rbb3 on flash pro w same bolts on but w full race exhaust and i made more power and i beat him. i’m not understanding.
both are k24a
The only thing that changes is the year. The RBB 3 and 4 are newer and have slightly better upgrades. Like the slightly bigger intake valve. But overall, it is not a bid difference to worry about.
USDM RBB3 can be the 1mm bigger valves if from the TSX-S, same as the rest if its JDM.
Awesome I have a 2006 rbb 3
Can I run a 5 speed from a rsx or do I have to run a tsx 6 speed bc my k24a is from a tsx
You can definitely run a 5 speed
@@Almostboosted does it matter wt year or where from I am new to all of this doing this swap on my ek hatch I wanted run a 5 speed from a rsx but wasn’t sure was possible because the motor is from a tsx
@@Almostboosted appreciate the response
Yeah it dosent. Matter. My friend swapped a k24 in his rsx with a accord 5 speed.
No problem
Question to upgrade a 03 Accord K24A4 auto.
Any possible upgrades? TSX cylinder head swap, intake manifold, or newer pistons?
Love my car and runs great. Just wish it had more power when I do drives up the grapevine.
If you try swapping a different head, you would need to change pistons because it would make contact. Your best bet is swapping the complete engine. And yeah, you could upgrade everything else, but it won't make much power. I'm sure ktuner has flash for the ecu, but it won't be that efficient.
Is The K24a JDM RBB better than my current k20z3 on my 8th Gen Si?
To be honest, yes, the k24a has its advantages. More torque bigger displacement. The k20z3 smaller displacement, les torque but more aggressive cylinder head and flow. I would wait until the k20z3 goes out, or you can interchange parts between them and hace a Frankenstein engine
Awesome good to know! The only problem I’m facing my car has 230k miles and just recently car overheated,blew head gasket, noticed coolant in the oil pan, so sadly it’s time to change out. What is your best advice to make this swap smooth transition?
Get an rbb 2 or 3 jdm k24a. Swap over from the k20z3, the oil cooler, water pump housing with everything. swap over the crank sensor, knock sensor. The intake cam sensor is angle different the vtec pressure switch sensor next to the vtec solenoid by the back of the cylinder head since jdm Engines don't have it. Get a CRV post mount. Flash your ecu with hondata or whatever you can find to tuned. And slap back the transmission. Optional yo can Swap over the k20z3 hear and or rsc type s oil pump kit with a 50° vtc gear
Head***
Awesome! Thanks for the helpful advice! I’m making parts list now and taking my time to gather everything I need before I get this projects started.
Been trying to confirm whether the USDM K24a2 has more aggressive cams than an RBB3 K24a. I believe that's what you're saying here. Confirm?
To be honest, I have not personally measured them. But every importer that I seen selling RBB 3. Is way more expensive compared to the RBB 1 and 2. Not sure if it might have the more aggressive cams, but I'm sure it has the slightly bigger intake valve.
Been trying to solve the same riddle myself. Based on my reading even the later RBB3 JDM K24a's stuck with the 04 USDM TSX cams - not the more desirable 06+ K24a2 USDM cams. As a result, in terms of power specs the JDM motors out of the box wont achieve as much peak HP however they do tend to make up for it in torque. Silver lining: this makes a drop in cam even more attractive on the JDM motors especially with 40+ degree VTC
I like how the jdm k24a has a bit more torque.
Correct
@@Astonmarvinusdm tsx 04-06 is different from usdm tsx 07-08. Both k24a2
Latter has slightly beefier rods. Intake valves are 1mm larger. And cams are better from what I’ve read.
However what I’ve also read is that even in the usdm the rbb1,2,3,4 castings don’t always correlate to being an 04-06 vs 07-08. Meaning you can’t rely on it saying rbb3 or rbb4 and assume it’s an 07-08.
The consensus has been that it’s not a 100% guaranteed way to tell.
Can a 02 rsx type s water pump housing fit the jdm motor? What else would I need to use for ac and ps ?
I have seen people use rsx type s waterpump housing. With there k24a even with RBC manifold kinda of a tight fit. For Ac and Ps you would need a k20 or k24 compressor, the rsx type s powersteerimg. Preferably and with a string measure to see what serpentine belt you would need. But I seen hybridracing also have a powersteering kit like lines and hoses. And a Ac kit too to help with kswap.
Appreciate the Jems 🤝
@@rvmangvd4050 any time
Isn't the connector for the JDM alternator different from the USDM one as well?
No is the same obd2 green plug I've seen it also in black.
@@AlmostboostedI think he means the mount not the plug
I see.. 🤔 yeah, the jdm alternator has a different mount, but I seen. Some with the same usdm mounts.
I am throwing mine into a 2001 Honda Insight. Did I hear you correctly that i might not be able to use Hondata with the Japan variation? If anyone has any info on this swap, I am looking for an ECU, Wiring Harness, Hasport Mounts, Accord Parts, I really want to make mine AWD. I am also wanting to do a Naturally Aspirated Build with lighter Crank, Longer Rods, ARP head studs, Higher RPM Pistons, K20 Type R Head, K20 Oil Pump Swap, Warlboro fuel pump are among many on my list for the build.
Im sure you should be able. I know of a guy on my ig that did it but not sure if he would share info. He said it was a lot of research.
I have the JDM k24 rbb3 swapped into a 2004 Ep3 and both Kpro and Ktuner works on the setup. I do have a vid when it was on the dyno while tuning on Ktuner.
I have a k24a jdm engine in my 97 dx hatch. I use hondata kpro v4
I would like to know if the half shaft from the k24a2 ( TSX USDM) works with the axles from RSX base model . Thank you
I belive the tsx and accord half shafts are to long, manual rsx, ep3 and the si should work. I bought 06 to 11 civic si ones.
44500-SCV-A00 all the compatible intermediate shaft share this part number
@@Almostboosted I ask you, does it not matter if in the case of a half shaft of an element it is automatic or manual?
@vocs03 from what I heard, yes, you can use auto. In fact, I saw a crv auto with the rsx style intermediate shaft at the yard.
@@raysb240sx so the half shaft from the k20z3 fits in the block of the k24a2?
Do u have to do anything to your engine to keep it from rusting if you're not planning to do anything to it but stored it for 1 year?
If you want, you can spray a bit of wd40 on all the steal parts and cover it.
How can you tell if its a k24a 3 lobe?
In the side off the head by whete the camshaft sensors are located just about the side water neck. It should say RBB- either 1,2,3 or 4
Thank you
@@Almostboosted mine says rbb3 does what does that mean ? Is that the good kind 😂 I knew to all this cause I recently purchased a FA5 sedan with a k24a swap and I looked at the crankshaft sensor and it has a rbb3. What car do these come from and how much power does it push
Yeah, it is a good k24. I have an RBB-3 in my eg hatchback. Is a 2006 it has 36mm intake valve. I made 240hp and 195ft lb.
@@Almostboosted I'ma do a oil change tomorrow. What oil should I use ?
skipped all that stuff and stick with k20z3, k20a2, k24a2.. still put good amount of power also with everything else and probably better than a k24a jdm imo..
Thanks for your honest feedback. But the jdm k24a is still cheaper and comes with fewer miles and has more torque for the money.
Sure buddy, find me a 45k mile USDM k24a2 for $999.00 delivered. Go on and try. I'll wait.
