RBC Intake Manifold Install- 9th Gen Civic Si
HTML-код
- Опубликовано: 4 окт 2024
- So in this video I cover installing an RBC Intake Manifold onto a 9th Gen (2014 to be exact) Honda Civic Si. This will be the same process for all 9th Gen Si's. Its a pretty simple process.
-remove air box/ cai/ sr intake
-disconnect throttle body and all vaccum and coolant lines
-remove fuel rail
-remove plastic intake manifold
-remove runners
-reinstall rbc along with coolant delete/bypass
-reconnect all vaccum and coolant lines in their correct locations

A man not afraid to wear gloves while working,respect!!!
That habit died out quickly lol
Just bought a 9th gen and your videos are extremely helpful! Just installed Acuity shifter bushings and springs.
P.s Lower tie bar
Awesome bro I'm glad to hear that! Thank you for the support and noted!
Watched this when I got my 14 fg4.
Watched this a year after my rbc swap.
No regrets lol
good video where I can get everything I need for the change
It’s always nice to see a fellow 9th gen as well as fellow coworker lol. Keep doing your thing man.
Btw that lower bar would be interesting lol
Haha thanks bro! Att during the day. Working with the car at night lmao.
Thank you! Finally a video explaining how to install this
This helped me before but I didn’t know about the extra vacuum lines in the back of the Intake manifold
THANK YOU THANK YOU, was looking for a video like this!
You're very welcome. Hope it helps!
just bought my 9th gen.all video really helpfull
I hope u aint adding the rbc.. pointless mod on the 9th gen unless u building ur motor.
i really love that injector cover
Nice video great detail , you could delete the coolant to the throttle body and those vacuum lines 👍👍👍
Very helpful thank you
You are very welcome my friend. Glad it helped!
awesome video!
Clean bro how she holding up today
That engine bay looks neglected
It definitely is 🤦🏻♂️
Tiny tear in o-ring gasket for the injector. “Time for a new injector” 🤣
Yeah I definitely needed a new injector. Because I was rbc swapping it 😉
@@AaronShirzadi_mar5hal I gotcha man. I’m thinking about ordering one for my k24z7 but I’m nervous haha. Scared I’ll order the wrong setup cause there’s so many options
Nice work mate .
I got a question?!! Pls
About the water adapter can't we use the original way that is available on the manifold itself ??

And again, I’m an SiClub member myself but all civic love is welcome! 🤙🏽
Where did you buy the “coolant delete “ or where you buy you intake kit plz
I'm curious, why is there a coolant delete on the intake? is there a benefit to it?
I believe it was to help reduce some of the heat soak to the air going into the engine. The cooler the air the better.
Plug n play? No need to calibrate the stock ECU?
How do search for this manifold? I have a 2012 civic si.
i was looking at the prl website, i see the have the whole kit. if i buy the whole kit, would that work for my whole setup? would i have to be more things, because worries me is the coolant delete part.
You didn’t have to drain your coolant?
Hey bro that breather vent by you battery and clutch bushing thing on the top of the transmission at 10:13 . I noticed it doesn’t have the cover lost mine the other day . How long has yours been like that and is it okay to run the car without it
Honestly I didn’t even notice that and you may have just helped me solve my leaky transmission problem!
What is the point of the RBC install on a stock K24? The RBC is only good past 7500RPM.. And you lose some of that mid-range torque. You'll need to build the head and go with a 50* VTC gear as well as cams to take real advantage of the RBC. But you are kinda playing with fire revving a k24 past 8K. 8K on a k24 is super fast engine speed. I wouldnt feel all that safe revving a stock K24 higher than like 7800 without building the motor. Im sure plenty of people have gotten away with it, but its a ticking time bomb.
did you have to reprogram the ECU ??? or do anything
Yes a re flash is definitely needed.
Good evening, my friend, I'm going to import this manifold into Brazil. I would like to know the costs of the manifold design, and exactly where you bought .. how much would this kit
Hey bro this videos great ! Question tho after you installed everything did you have to run a tune to use that Rbc intake manifold oh and the coolant that accidentally spilled a little bit did you just add to the resivior ?
Yes a tune is required.
Yeah definitely want a tune. And a little bit escaping isn’t that big of a deal but I always burp the system after disconnecting any coolant lines.
Where can I get this manifold
where u buy the coolent elbow adapter from
I bought a 2012 project si I need help I habe some wire with plugs laying around confused where they need to be plugged in... Can you help pleaee also I dont know how to check the temperature coolent gage on these car cause it doesn't show like older models on honda..
Awesome video my dude. Got a question, K24z3 will this rbc fit? Ktuned rbc is nice
That’s the one in the tsx right? If so I believe it should bolt right up. Haven’t worked on one of those though so don’t quote me haha
That’s an Accord dude .
Where did you get your adapter kit? The only one I see on PRL's website is an adapter plate with a round hole to cover the "peanut" shaped coolant hole of the RBC manifold. Yours is like another differernt piece. Very nice video by the way, i like your installs. I subbed a couple videos back
Hey man thanks for the support! As for the swap, I bought the kit from a friend and it had everything included. The one I'm using is the prl bypass/ delete and I know I've seen them around on a few sites. Can't find one at the moment but if you're looking for something similar there's one on kseries pros site made by ktuned. kseriespros.com/k-tuned-intake-manifold-coolant-bypass-k24z7/
I can look around and link a prl as soon as I find one
Cool thanks man! Can you tell me what line you ran to that throttle body spacer?
That's a vacuum line that I believe isn't doing anything anyway so I'll probably just delete it.
Whats throttle body bro ? And spacer ?
What’s the point never said how much more performance enhancing it provides
What's the difference between this manifold and the KTuned Side Feed Intake Manifold? Ktuned is like $1200 dollars...
Nice vid. Question, how did you get your valve cover and plastic cover over manifold painted like a galaxy
The plastic cover over the manifold comes off by simply in screwing the two 10mm bolts that hold it down. The valve cover is a little more in depth but you can watch my other video for reference. ruclips.net/video/7v7PAWgdAmQ/видео.html. And after that you need to either hydro dip it yourself or send it to someone that hydro dips them. Contact streetlocity@gmail.com and they can point you in the right direction 🤙🏽
Nice video! I have myself a 13 civic sedan. What is the benefit of installing this mod? Also if you have any of those giveaways left here’s my comment :)
How does it run man? I've heard anywhere from 30-40 hp gain off this swap with tune. And great video as always bro!!
It's definitely a noticeable difference and thanks bro!
You get anywhere around 15-20whp in vtec but lose some low end tq.
Yeah it's definitely noticeable down low the loss of torque. At least the tune I'm running
What's the increase bro I'm thinking about doing this
lol, you will not see anywhere close to a 20-30 HP gain unless you are putting up big boost. as far as NA you lose most bottom end but at around 7k rpm ( at redline) it makes 4 1/2 - 7 HP. so basically if are going to only want top end it is a good swap with cutting torque at low end. but it does give it that kool sound.
Just askin new to ur channel do you put maintanance fluids in the car? If so which ones?
Im picking up an 8th gen gonna put some headers intake maybe exhaust so new to this hows ur intake going lol
Welcome to the channel and if you’re buying the car I’d recommend doing a fluid change (coolant, manual transmission fluid, oil, bleed the clutch and brakes). My intake is still holding up as it is lol. It’s as “custom” as it can be haha
Would that skunk 2 throttle body adapter work on my 2012 si? I’m also doing an rbc swap
I haven’t personally looked into the s2 adapter but if it serves the same purpose and matches up with the rbc then I would say yes but don’t quote me lmao.
Hi man, great video! I was wondering if you *NEED* a tune, obviously for CAI, headers, and manifold you obviously need a tune but is possible to not require a flash tune? I watched a video before and I've never seen anybody do this method before, he would install the RBC manifold then wait the next morning and cold start the car and hold the rev at 3000rpm to "restart" the car ECU as you have much more air into the engine, after he is done this for a few seconds, he proceeded to turn the car off and happy days. Does this really work?
I just ordered my rbc kit, currently tuning with vit, should have waited but hoping he will let me change. the coolant delete was included in the prl adapter kit correct? If not which brand did you use? Been using your videos alot lately. Thanks!
Thanks for the support bro! And I bought the setup from my friend. I believe the coolant delete is separate from the tb adapter but prl may have a kit that offers both. 🤙🏽🤙🏽🤙🏽
Aaron Shirzadi did you use k tuned delete? No problem, your videos help me save $, least i can do.
Aaron Shirzadi also what did you edyno with this setup, same as me except i have full race full exhaust, you had q300 and rv6 correct?
i have a8thgen coupe i was told getting a skunk 2 intake manifold isnt worth it what are your options? i would like a shift knob
I personally haven't used the skunk2 mani although the idea is extremely similar to the rbc. I feel that the mods are only as good as the tune on the car. That's the key factor with any bolt on imo. And noted 🤙🏽
hey so i bought this for my 08 accord and my stock injectors won’t fit... what are u using??? i really need to know to finish my build
How many inches it’s the filter that you used for the intake ?? Lmk please I need that one!!
Love your vids. Not enough love for the 9th gen. Do the fuel injectors have a maintenance interval of when to change?
Thanks bro. And nah not really. You can get them flow tested and such but when you swap out the stock injectors to the Rdx injectors you should be gucci.
Haha you work for Att brotha? I do as well! I manage one in PA. Tune it and you will see huge top end power but lose mid range.
Actually I don’t work for att anymore after 6 years of managing lol. I’m actually working on cars now 🤙🏽 and I had a tune. But I’m boosted now so that rbc long gone
What is an rbc im? Is this an aftermarket brand? Or is it an im off off another k series?
It’s the manifold from the 8th gen. The k20
@@AaronShirzadi_mar5hal ahhhh its all clicking now loll😆😆 where is the rrc intake from?
What injectors did you swap to? Also I have the Skunk2 composite CAI, fill I still be able to have it run down my wheel well area?
Did you get it tuned?
I have a 2004 rsx base. And I want to install a RBC intake manifold. Do I need to have it turned after I install install it
Nice video bro . I’m just a little confused how you needed the coolant delete but for the prl kit a coolant delete is not necessary how is that possibles please lmk I’m very confused
With the rbc being cut the coolant bypass or delete is necessary and in doing so you help reduce heat soak. Hope that helps 👍🏽
Aaron Shirzadi yesss that completely answered my question thanks a lot i knew I noticed your rbc was a lil different on that side thanks a lot.
Also how did you solve your caí problem did you just have to roll with it short like that
Yeah right now it’s still a cold air/short ram intake lol. Luckily I was able to make do with parts that I had lying around. I know there’s an adapter you can buy that will make the 9th gen skunk2 Cai fit better. Could also just get a coupler and make it work 🤙🏽
Aaron Shirzadi nice thanks for the tip now I’m prepared for an rbc lol
Hey nice video.. I just bought the rbc intake manifold I’m guessing I have to have the coolent delete done when I do rbc intake manifold? And do you recommend any gasket for it?
Technically you don’t need to do the coolant delete but most people do. As far as gaskets you want to get the hondata thermal manifold gasket that fits your application. I had to trim the one I had a little to get it to fit up with my setup but it worked none the less 🤙🏽
Aaron Shirzadi thank you for your reply I appreciate it !
I got a question
My civic si 2012 has the stock manifold
And it’s like plastic
What do u think if I change it for the Acura txs aluminium manifold
It’s better or the same shit
Not sure if it works the same as the rbc.
I know in the video u showed what u bought to install it but can you write it out so I can know. Thank you
What I had for this was as follows:
- cut rbc intake manifold
- prl coolant bypass
- hondata thermal intake manifold gasket
- prl throttle body spacer/ adapter
- hondabond (not hondabond4)
- honda/acura coolant
That’s all I can think of atm. If I think of anything else I used I’ll be sure to update the post 🤙🏽
Nice video bro thank you .... but at 4:43 the bolts underneath how did you get those off its close to impossible they're in such a weird angle even with the car jacked up
Thanks man! And tbh the first time I did this I used a 12mm ratcheting wrench and did quarter turns for a good ten minutes per bolt. Definitely cut my hands up with the weird angle. But if you get under the car and use a long extension and a wrench or impact gun that seemed to be the easier route for me. Hope you get it sorted and if you got any other questions you already know where to ask 🤙🏽
You didn't use the prl adapter ?
Is their any other way you could connect the throttle body harness with out cutting anything ?
Unless you take apart the loom it’ll be difficult to get it to reach. I just sent it 🤙🏽
What spacer is that ??
did you have hondata or straight bolts on ?
cuz I'm planning to buy one but i don't know if i need hondata or just plug and play
Did you do any cleaning to the head surface of where the intake manifold goes?
I carefully wiped it down with a rag and scraped away any debris that built up yes but since that’s normally sealed from the factory there isn’t much to clean on the actual mounting surface. But it’s always a good idea to clean and prep anything you can 👍🏽
What kind of injectors would I need if I don't plan on widening the bores?
Depends ultimately on your tune I guess. But I used rdx injectors. Pretty sure they’re 410 or something like that. I’d go with those. You can splice you’re old connectors or they sell a quick connect adapter.
How much does RBC cost, and what would I need to make it a good set up??
It depends where you get everything from and if you get it cut like mine was. It can range for the complete setup anywhere from $450 (what I sold mine for) to $700+. Also if you aren’t doing the installation yourself you’d want to take that cost into consideration as well. Plus to make it worth your while you would want to have the car tuned so there is that cost too lol.
Aaron Shirzadi Thx for quick response.. I seen some places where they cost $140 for k24z manifold kit. I just wasn't sure whether that's all you needed to make some gains or add injectors along with it or something! I'm already tuned n have a flashpro so I don't really need to worry about that, just wanna get a re-tune with an RBC now n get best possible results!
Yeah whatever tune you have now will need to be changed to compensate for the rbc. And yeah my setup was the intake manifold with the coolant delete, the prl coolant bypass and Rdx injectors.
Yes most people run the rdx injectors so they don’t have to bore out the stock injectors because most tunes with the rbc on the 9thgen require more fuel
Can you use the stock 9th gen feul injectors with the RBC Intake Manifold or do you have to buy new ones?
How did u extend the throttle body harness ? Cut and rewire ?
Exactly
Aaron Shirzadi what gauge wire ?
Can I still use a 9th gen si intake with RBC with stock thottle body ?
Are u vit tuned? Love my swap but had prl bore my injector holes out to fit the 9th gen injectors and match the Zdx tb. How u liking it?
I'm running a tune but not from vit. I love the up top. Really opens up the 9th gen. I have missed the lower end torque though but I've heard mixed things. All comes down to the tune. But so far I can't say I don't like it lol
Cool man. Vit really has the rbc figured. I'd give it a try. Not plugging his thread at all it's just I couldn't be happier. Torque loss isn't as bad as people say.
Good to know man. I'll definitely give it a go 🤙🏽
Sorry one more question what injectors did you use that went right In with the stock fuel rail and into the rbc with no problem?
No worries. I used rdx injectors (410cc) with plug and play clips.
Is that a k20 gasket you used for the IM?
Is it necessary to do the coolant delete to install rbc or you dont have to?
No it isn’t necessary. This manifold that I bought just happened to be pre cut with the coolant bypass. I think you need a specific gasket though due to the difference in the size/shape of the passages
Question, I’m doing the rbc but I’m not sure where to connect the vacuum hole on the rbc that’s located on the passenger side. Where did you connect that to?
Pretty sure I connected that to the pcv that’s right below it
Aaron Shirzadi I see cause I’m reading online and they made a T tube . Just wondering if you did the same
Yeah you can do a t tube to a catch can if you want. I’m going to do one that goes from the pcv line to a catch can back up to the breather on the valve cover
No tune?
Brot u porting the hole where the injectors enter?
Do you gotta drain anything?
Yes. When you remove the coolant lines and runner your coolant is going to drain. You may be able to get by without letting it all drain but you definitely want to bleed the air out of it by burping it.
Aaron Shirzadi alright thanks bro
How long did you let the Honda bond cure ?
How did you extend the throttle body harness?
Just clipped the wires and soldered in extensions. Just leave yourself some room. Don’t cut to close to the connector.
You need a tune for this correct?
Did u use stock throttle body
Did you reuse the stock TB??
Do you have cranking problem with your rdx injector?
where do I get the rbc intake kit you installed?
Hey bro I have another question I have the sk2 pro series idk how different it is from the rbc but what did u do with the pcv hose it doesn't have anywhere to connect now and also the small hose right above your knuckle around 8:09 - 8:13 idk what to do with them thanks
In the rbc it has a bung for the pcv but like my kraftwerks manifold it doesn’t. Right now I don’t have it connected to anything but I am going to run it to a catch can. And the small vacuum that’s near my knuckle I have connected to a line on my prl tb adapter
Aaron Shirzadi interesting and the prl tb adapter sort of works like a tb spacer ? Or what's the purpose of it I'm thinking about getting it
Yeah the adapter is basically a spacer. Makes the 9thgen tb work with the rbc. I have it on my kw setup just as a spacer.
Do you have to extend the throttle body sensor or there enough slack to reach
If you open up the harness I’ve heard there is enough slack but I just extended mine by cutting and adding wire and soldering it in.
@@AaronShirzadi_mar5hal sweet thank you so much, video was very helpful.
Hi rdx injectors are 8gen and 9gen same ?
What other mods do you have on your car that compliment the new IM? I’ve read that CAI, Catted DP, exhaust, RBC IM, Hondata flash pro + TUNE can get 200 WHP. What experiences have you had with these mods?
I'm up to 210whp without the RBC.
I'm wondering what I would gain from this.
Was the coolant delete necessary?
Being that my rbc manifold was shaved yes the coolant delete was necessary.
Are those stock pressure injectors? Just replacements since that OEM one was bad? Did this come as a conversion kit or did you have to piece it together?
They are the rdx injectors. I believe 410cc
Would the stock throttle body fit with the RBC
Where did you run the pcv hose to?
Did you have to get a tune after the install?
I can use some springs!! Haha. Did you notice any gains? Or arent you tuned yet?
NOTED! Lol and it's the infamous rbc swap debate. Me personally am on a tune for my setup. What I notice is two things which are somewhat the obvious. I notice a decrease in torque down low. Up top I also notice it opening up more if that makes sense. Of course this all has to do with my tune and car but I know there are good things and not so good things that come with the swap.
Do you have to change injectors wen you go to the rbc?
I did yes. Do you have to? Not entirely sure the 9th gen injectors would fit the rbc or not but I believe everyone that goes rbc gets rdx injectors.
Good evening, my friend, I'm new to this preparation world. I want to make my car with the RBC or Skunk2 manifold. Where can I find it full? thank you
You can check the prl website or procivic or kseries pros.
Hey bro quick question how did you extend you’re throttle body harness??
I honestly snipped it and extended it with some 18 gauge wire. Soldered everything up and no problems as of yet. It’s better to crimp since the engine bay has a lot of heat in it but soldering did just fine for me. Just match the wires up by color and add what you need 🤙🏽
Alright man thank you!
What injectors did you buy?
Where you get the gasket from
What coolant delete kit is that
Prl I’m pretty sure
where you buy the gaskets
and the coolant delated ?
