K24 RBC Intake Manifold Swap - How To Do It (& Everything You Need To Know)
HTML-код
- Опубликовано: 22 авг 2024
- Today we swap out the factory K24 intake manifold for an RBC manifold. This flows a ton better since we're going turbo on this car and is a factory Honda part that you can order directly brand new.

can i use that manifold on a CR V K24 motor? want to get rid of that plastic POS, but dont want the check engine light issue....
It'll probably throw up a code. I could probably try it on mine for you and find out.
Good job! That RBC manifold is way better for performance than the stock, long 2 piece one the K24 came with.
Thanks for this video. I'm new to k-series (in the process of my first k swap) and I have a k24 as well.
thanks dude
Thanks for checking it out. Feel free to reach out if you have any questions. There's plenty more Civic mods in the queue, so stay tuned!
howd it go im buying one soon
@@onlyunojhuno Everything is going great! My most recent video about the Rear Control arms has a quick running clip at the beginning that you can check out to hear how much air that thing pulls in even at idle. Feel free to reach out if you run into any issues and have fun out there!
Man that helped me alot ! one thing i didnt see you do is what did you do with the top hose between runner 2 and 3 ?
Rudy, thanks for checking out the video and happy it helped out. Good catch, I forgot to mention, to block that off you can use vacuum port caps or reinforced polyurethane caps if you need it to withstand pressure from a boosted application.
New here on this channel its a really nice video, just a question though, are you on stock ecu? Or did you have to get tuned after the rbc install? Thanks!
Thanks for the feedback and checking out the channel! I'm on KPro and didn't have to make any changes to the tune. I don't see any reason you'd need to swap ECU or get a tune just to run it since all the sensors swap over. It does open the door a little more when you do decide to get tuned, however. More content coming soon!
@@C4Race thank you!
So it bolted right up to k24 or did you need to do something to the coolant on the right of the manifold where the k24 one goes over?
It bolts right up. Since this is a swap for me I used that coolant port for my coolant temp sensor.
Now I know cl7 intake just pnp to k24 head. Thanks bro
Whats the spacer for on the throttle body do you need to run that? Or can you just mount stock tb to the new manifold
So you didn’t need an throttle body adapter
Actually, you do need an adapter if you are using the K20 throttle body, I just transplanted the one I already had on the K24 manifold. Sorry for missing that.
@@C4Race hey there nice k20 inlet swap what's the name k24 inlet ? Call thanks 😎👍🏾
@@geo93_trelawney I used the Hybrid Racing RBC adapter. There's quite a few companies out there that make them but you can pick up the Hybrid Racing one one their site (or their ebay storefront) at the following link. Be sure to get new OEM throttle body gaskets to avoid vacuum leaks! you'll need 2, one for the adapter-to-manifold side and another for the throttle body-to-adapter. www.hybrid-racing.com/products/hybrid-racing-k20a-a2-a3-z1-throttle-body-to-rbc-rrb-rbb-intake-manifold-adapter-hyb-tba-01-64-c
Old post but thought I would share some knowledge. You can also use an accord throttle body without adapter. I'm still using the tsx manifold with my swap with an accord throttle body from the junkyard.
Thanks for the other option! Didn't know an Accord TB would work.
Planning on doing this to my k24z3 will I need to tune it after? or is it just bolt on no tune?
Do you kno if the a2 manifold fits an z3
Nice one👍💪🤝💯🔥
Thanks for the visit, there's plenty more coming soon!
@@C4Race you're welcome brother, that's why we're here to support you🤝🤝💯
This video can apply for k24z7? And what about the coolant port? Is a direct fit rbc with what gasket? I have so many doubts cause in other videos that i saw every body cuts the rbc and re-route the coolant port
I'm not as familiar with the z7 engine so sadly I can't really give you a good answer there. My application is for a K24A2. In my case, I can use a factory K24 gasket and retain the coolant passage. I think the difference comes in with a K20 head and an RBC since there isn't that passage. Again, not sure about the difference between an A2 and a Z7.
Woukd i need to trim the coolant passage from my k24z3 and run a coolant bypass. Or could i just drop in the RBC manifold with full gasket
Not sure about the Z3, but I know that there are different coolant passages based on the head.
Thank you for the video. I'm about to install an rrc on my k24 and the details are quite helpful to know what i need to do. I have a question: Did you have hood clearance issues with the vacuum port and hose?
No problem with hood clearance on my setup.
So what's up with the big ass holes on both strut towers ??
Previous owner did that. I had to look it up also. Evidently when you slam the car the upper control arms contact the shock tower so the super low static guys cut holes for clearance. I have some plates that I still need to weld on to fix that.
That's so rough lol.
Nothing good comes from the stance scene 😂
Is it possible to use on an A8 motor with DBW?
What does the top vacuum port connect to? The one nipple between the fuel rail and valve cover.
hey quick question are you still using the k24 injectors or aftermarket
For now I'm using the stock K24 injectors. Once I get the engine build finished and turbo on, I'm going with some Bosch 2200s. If you want something with a little more juice for some NA power you can use Acura RDX injectors which have a higher flow rate, are super cheap, and you can pick them up at Honda. Part #: 16450-RWC-A01 for a set of 4. You'll need some jumpers or rewire them in. Lots of places sell them as a bundle.
Port the tb to 80mm and use ktuned 80mm tb you will see more power
Did you still use the adapter plate for the throttle body after the swap? I'm trying to get this set up on my K24A4.
I did. I just transferred the adapter plate over from the old manifold.
@@C4Race thanks for the reply!
Wich thermal gasket do you use for a k24 engine with rbc intake? Part number?
I used the one from K-Tuned. I use a lot of their stuff. Very high quality k-tuned.3dcartstores.com/Thermal-Gasket-brIntake-Manifold_p_227.html
Do you have to change any wiring for the new manifold or it all plugs up the same? Also what engine harness are you using
No modifications needed in the harness. I use the K-swap harness from Jack Spania Racing. Here's a link: jackspaniaracing.shop/products/k20-k24-k-series-tucked-engine-harness-for-honda-acura-1
@@C4Race awesome. Also another question. I just bought a k24a2 for my ek. It’s the usdm motor. Do i have to change the water pump housing or relocate any accessories or anything like that. I don’t plan on keeping ac or power steering.
Thats awesome! You won't need to change anything with the USDM engine. The water pump housing thing is only for JDM and only becomes an issue when you go to replace the pump itself.
Will the rbc manifold fit on a k24a2 rbb head?
Shouldn't have any issues. My motor is an RBB JDM K24A which is the same as a K24A2
Do you guys know if this is gonna fit my k24z3?
Will an rbc fit to k24a4 head. Maybe some trimming?
Going to install rbc manifold to my stock 05 type s engine. Do I need to upgrade fuel rail?
Should be fine. I used the same fuel rail on both the K24 and RBC manifolds.
Will the rbc accept stock injectors and what spacer and things would I need to put in my stock plz help me I have the k24a4
I'm currently using the stock K24 injectors with no spacers. They plugged right in.
@@C4Race sir thank u so much so do I just need the rbc manifold and the rbc adaptors or throttle body boss can u send me ur parts list on your a4
would one of these mainfolds fit on a k24a4?
does this mod works on k20a from second gen honda crv..?thanks in advance
It should since the K2x heads are very similar, but definitely do a little more research into your specific application before committing.
I installed mine the other day it ran horribly I had to switch back to stock manifold didn’t want to shift out of 1st gear. Is there any other modifications I should have done? I
Did u use the rbc adaptor
Did you make your charge harness? Subbed
I did actually, pretty straightforward. Let me know if you want any details. Thanks for checking out the channel!
I wanna run this manifold on my 7th gen accord with a 70k tuned tb im have problems with iacv the one the accord looks different from the one for the k tuned tb I wound if I have to run a ep3 or rsx iacv @C4Race
will this swap work on a k24a8? (07 accord 2.4)
What is that sensor on the right side of the intake manifold infront of the throttle body?
That is a MAP sensor, the one right next top the brake booster vaccuum line.
Sorry I meant of the sensor to bolted in at 11:03 beside the fuel rail
Gotcha, the vertical single wire sensor is a coolant temp sensor. That typically is an air bypass valve that is thermally actuated and runs from the intake tube to the manifold during cold starts then closes as the engine warms up. I removed that and placed a coolant temp sensor in its place. There's a few companies out there that make them.
The videos that don't show the process of removing the RBB2 are useless.
What manifold is it exactly maybe I can find one in the junkyard
Off of a RSX type s
Stock RBC manifold
Where can I get the fuel inyector by Ktuner
I bought it directly from KTuned: k-tuned.3dcartstores.com/
Is it plug and play or do I need a tune
Should be plug and play. Once I get the turbo on I'll be getting a tune on the KPro. For now it's just running a base NA map.
Yes I’m not going turbo or anything big it’s for my accord 2003 ex 2.4 ivtec just want a little more push on it

@@franciscoesparza410 Honestly, I'd look at other mods before swapping the intake manifold if you're just looking for a little extra pep. The RBC may flow better and is great for boosted applications but because of the length of the runners compared to the factory K24 manifold you *might* gain some more horsepower (likely single digit if that) but will defintely lose some torque. What you will mostly feel driving around town and some light spirited driving, torque will be the bigger contributor. So in reality it might feel slower outside of track-day-like events. I'd recommend looking at intake, header, exhaust first then start stepping into the bigger mods.
And can you also run a rbc on stock ecu?
Which k24 series are you running?
I'm using a K24A2.
@@C4Race I have K24A3 so i was wondering to buy RBC but i was not sure if on the k24A3 will be bolton without modification. so a2 and a3 are basicly the same engine so i can mount the RBC without modifications.
New here. I sub
Thanks for the support!
No Fuel Return Line ????
There's a return line direct from the regulator. My FPR is remote mounted on the shock tower instead of directly on the fuel rail.
no torque wrench in sight!!!
