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.

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.

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.

@Almostboosted 8 месяцев назад

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.

@user-uf3ls3lw7q 11 месяцев назад

What needed to swap this into an rsx type s and will i have clearance issues?

@Almostboosted 11 месяцев назад

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.

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..

@Almostboosted 2 месяца назад

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.

Should I just get the USDM k24a2? I heard the waterpump has to be configured and im looking to keep P/S

@Almostboosted 6 месяцев назад

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.

@Astonmarvin 8 месяцев назад

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?

@Almostboosted 8 месяцев назад

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.

@Astonmarvin 7 месяцев назад

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

@Almostboosted 7 месяцев назад

I like how the jdm k24a has a bit more torque.

@Almostboosted 7 месяцев назад

Correct

@neverknowsbest4994 6 месяцев назад

@@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 ?

@Almostboosted Год назад

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.

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.

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.
