- Everything You Need to go R18 to K Series
By Brian Gillespie and Aaron Gaghagen
Looking for a quick list of parts you'll need to do a K swap in your R18 powers 8th Gen Civic? Look no further. These are the parts you'll need if you're swapping your R18 for an 8th gen Si engine and transmission.
06-11 Civic Si exhaust header
06-11 Civic Si catalytic converter (to be legal)
06-11 Civic Si or better exhaust (so you aren't limiting the engine)
06-11 Civic Si radiator hoses
06-11 Civic Si heater hoses
06-11 Civic Si air fuel sensor and secondary O2 sensor
06-11 Civic Si ECU
06-11 Civic Si engine wire harness and charge harness
06-11 Civic Si shift cables
06-11 Civic Si intake air tube, airbox and MAF sensor
We opted to installed a K24A2 from a TSX so we also grabbed these parts. Some needed more than others.
06-11 Civic Si intake manifold (optional)
06-11 Civic Si throttle body (optional)
Hondata FlashPro (to get full potential of the K24A2)
06-11 Civic Si oil pan (this is where the rear mount attaches)
The deeper than normal K-series oil pan found the 8th gen Civic Si needs a deeper sump. One option is to modified an 8th gen Si oil pump to clear the K24 crank pulley. It can be used with the K24 oil pump chain, guide and tensioner. Some people have gone without doing the pump with the deeper sump, but I don't recommend that, especially if you plan to bring the car out the track. We opted to use a JDM FD2 oil pump with chain, guide and tensioner.
Lastly, there a couple of other custom parts we used. We opted to keep the hydraulic power steering so we had a high pressure power steering hose made and used a TSX PS pump with it. Also we used some PS fluid resistant bulk hose to make a feed line for the pump.
To get the Si ECU to work with the non-Si cabin harness we made an adapter harness. Parts to make the adapter harness were purchased from Corsa Technic. For more information on building your adapter harness, check out this video. • 8th Gen K Swap R18 to ...
Don't forget that you will need to have a dealership reflash your ECU and MICU to get your key and car to play nicely with your new swap. It's kind of a pain, but it also gives you an extra layer of security to not allow someone to start your car without the real key.

@@VTECAcademy Any thoughts on the rod stroke ratio of the K24 when it comes to track use? Thank you
I daily a Nissan that I swapped in a SR20VET from an X trail, and recently bought a civic coupe this 💩 keeps getting more expensive. They need rehab for car guys.
Listening to Brian talk interspersed with VTEC revving noises is ASMR for us car nerds. Love it.
Ahahahaha! Next video: 10 hours of Brian talking with VTEC sounds.
Cool video. Thanks Brian!
You guys are brilliant!
Watching here in Philippines.I owned a Civic FD 2008 model,Manual Transmission with 1.8L engine.More power to you Sir. 🙏
I have 2009 honda civic EX black coupe that I purchased from my Mom. I wish I had a Si now. U Recently learned gow to drive standard transmission 5 speed on job training. figured it out on my own pretty easy. Thank you for this informative video. been looking for one like this. Keep up the good work. 👍
This has been an informative build.
Thank you for watching! Other than Si Civics, the 8th gen has been slept on.
Awsome build guys 👌
Outstanding information as always! No replacement for some additional displacement!
Thanks Vic! That R18 is just sooooo utilitarian. We need some power.
Great content. Would like to see you guys do the same for a K24 swap into an EK? Surprisingly, there are not many videos showing what needs to be done for that swap.
This is glorious. Thank you so much.
You're very welcome!
Thanks for this series. I have a LETHARGIC R18 auto EX sedan & CANT WAIT to swap it, soon as I get a newer daily..
Ewww! This swap would be great for a daily too, but we understand the hesitancy to mess with your main ride.
You're a true guru... The things I've learned from you, what you've given me the confidence allowing me to learn and do the stuff I do and have...
Thank you Lee! That's why we do it. The more people enjoying their Hondas, the better.
@@VTECAcademy thank YOU!
Awesome, thanks for sharing the information...
Our pleasure! Thanks for watching and the kind words.
I saw this video the day it came out, took notes since I have an 8th gen civic and maybe one day I will do this swap. A week later I see metal bits in my oil change, so now I am back to make a shopping list. Thank you so much for all your information and helpful videos.
Did you happen to go through with the swap? Would love to see it.
I’m fixing to tear out the engine out of my car as well
Nice I always wanted to do this but never wanted to do the rnd
Great stuff as always guys! That mount kit is super trick!
The VSA on the 07-11 Si ECUs should be no big deal at all. My 09 Si racecar has all of the VSA and TPMS wiring and hardware removed and it doesn't care other than the lights on the cluster. Love the content, hopefully won't need to reshell the car for a long while but it's great knowing I won't need another Si chassis.
Yeah, I just bought an LX sedan to turn into a race car. I may even get some CSX body parts to make a fake Type R.
@@VTECAcademy love it! Excited to see that and the L15 Integra progress, should be ripper with the current GLTC ruleset.
Thank you for taking all the time and effort to make this video! I have an 06 FD1 Civic with an automatic R18 engine and as you probably now, it's the japanese version of this Civic and looks similar in most of the outside parts to the FD2 Type R Civic. I've had this car for 5 years now and I've always wondered if anyone ever tried a K swap into an R18 Civic. I read once that you basically needed to tear appart a wrecked Civic Si in order to use all the parts, but watching your video is pretty much about just purchasing the right parts! And look at that, you just listed them all for us here! And if I'm being honest , it doesn't look that expensive, considering the upgrade you'll be rocking on your old, good looking and reliable Civic. This is definitely on my wish-list for the next year, once I get my daily drive replacement, I'll start this K swap project with my FD1. Thanks again!
In Thailand the fd2 had a 1.8 the fd1 had a 2 L...
@@classybluev1139 Really? I'm pretty sure that all the FD2s had 2.0 K series engines from factory. As this is the Type R Japanese version. You must be talking about the FD1 Type S. Mine is the FD1 Type S Japanese version with a 1.8L engine and auto transmission. However, I know there are a bunch of different configurations for different countries, maybe you're right.
Literally showing me what I'm trying to do to my '07 lx coupe, 50k miles from my grandma, couldn't get a cleaner chassis to use
The j swap is the one that interests me
Outstanding content guys! Great to know if I can't get an Si at a good enough price. If someone could be "nudged" into making the PS hose, when we lived in the big city we could probably get someone to help. Now we live rural and having someone piece that together could be a challenge..
Thank you for watching! ParkerStore says they have "3,700 independently owned Industrial Retail locations" on their website, so there's a chance you could find one locally.
@@VTECAcademy Thanks guys!
I would also be interested in the power steering hose. it would be a great option for those of us that have a failed eps system and have readily available hydraulic systems from an r18
Great info however b series’s swap to Eg is much simpler (less part swaps needed)lol
But I will attempt in the near future
Just like back in the day when people used to say "just buy a factory B-series equipped car" instead of swapping a base model, this is the next version of that. Really excited to see these swaps happen more and more. This information is invaluable.
yeah i’m not doing all that crap. i’ll just buy a si 😂
@@unlimtedbosss When the SI tax gets worse than it already is, this swap will start to get really popular
That’s why say I wanna j series swap you can’t say buy an si for that
Id have a lot of fun doing this stuff too if I had all those 400 parts that just happen to always be "laying around in the back"
Great 👍
Thanks!!
Hold up I just thought about this I have a auto ex as my daily and I want a turbo k swap nice thank you guys
I can’t wait for his j series swap I been wanting to jswap my 8th gen lx but I haven’t been able to find detailed info on it I don’t wanna k swap everybody doing it plus I already have a j32 from a parts car
I love the content you guys put out on a regular. I specifically like the fact that the 2 of my most watched content creators, VTEC Academy and mighty car mods did some work together.. great stuff.. I am based in Cape town South Africa and I'm busy K swapping my 8th gen R18a2 euro spec.. my car is exactly 13:10 the same as a FN2 but it's a 5 door 1.8 .. I have an issue with my right hand side shaft.. it's too short.. now I'm trying to get shaft specs online but im not finding anything.. I just want to cross reference length and spline count to see if I can match up some stuff to suit my build.. are you able to assist? Thanks
Is it possible to swap r18 to k24 and keep the auto transmission?
I need a auto to manual swap video. 😊
Thank you for all the information. Getting just about ready to this swap into my daily 4dr FA1. I would like to get a couple of those hoodies any links for them?
I'd like to do this in my 08 4door civic.
Video begins with "it's as easy as doing a B swap on an EK"
Later in the video you begin explaining that holes will be required on a plate in the oil pan and hoses will need to be combined together special equipped from a shop if you're lucky capable of doing it.....well sir that just defeated your initial statement. Nonetheless great video I'm hyped for this because putting an R series back in is dumb when they are notorious for block cracking. I've probably only grinded and rigged a couple things for the b swap but this seems much much more advanced to me
Great content as always!! I'm already k swapping my civic 8th gen. My vehicle is already equipped with vsa, will it work the same with Si ecu? Or it's better to purchase a non-vsa ecu as mentioned? I still want the abs to work. Greetings from Greece!
I’ve done this swap and if you get the ecu from an 8th gen si and it comes with the key and the fuse box under the dash (micu) you do not have to bring it to Honda u can take the chip from key out and just get the original key programmed so you don’t need to change the door locks
Also this swap wouldn’t have been possible without vtec academy thank you guys 🙏🏼 they are very informative
im gonna try and just push my r18 to see what it can do. honestly ill probably be punching below a k series for the price of a k series but im gonna try it anyway
Hi friend
I love all the information.
Thank you.
I'm thinking on swapping a K24 , turbo charging it into my 4runner 89.
Using the stock tranny.
Any advice?
George
I wana see you guys do an accord
I have a 2004 crv with the 2.4 l vtec and I keep getting a p0139 code . Both 02 sensors are new. Could needing a valve adjustment be causing the code? Not sure if I really need a valve adjustment or not. Great video👍
I want to swap my or modify my current 98 crv, but I have no clue how 😂. This video definitely made me lose hope on the dream… I’m so confused 😅
🤩🤩🤩
Want that hoodie
Have you ever made a video on how to performance a R18 / automatic ? So that we could learn & do it to our vehicles
We have not.
Anymore info on that SEMA 8th gen si? i noticed it was jackson racing supercharged!
Vtec Academy dropping some knowledge right here. Makes me wanna do this swap. Would it be possible to the swap without the Power steering ?
It would steer like a pig unless you used the Si or Hybrid EPS.
R18 under rated engine but if bolt on turbo to get extra power till 230hp and 270 torque its not big deal event though with low boost 0.6bar .with good set up and tune this engine roar like lion in the desert.
Interested in seeing a 9th gen also go from R18 to K24.
At some point in the future, I’ll buy one of those cars
instead of changing out the oil pump, if you keep oil level full according to the dipstick, what is the draw back? The deeper pan takes more oil, but the dip stick will tell you how much oil to add.
will the 2005 Honda Accord manual transmission fit or do I need the Civic Si manual transmission?
Please do some videos on a d series, I am trying my hardest to find any info i can on them. I would like to know which variation of the d series is best to modify for boost, and maybe a good list of parts to do so. I have a 97ek coupe i am trying to build and the info or maybe a video or two 🤞🏼😂 would help alot!! Hope you see this thank you 👍🏼 i left this comment on an older video but wanted to make sure you saw it 😂
There is way to many information on D series, just google it.. best for boost is d16z6 or d15b.
@@civicpride1986 i have found lots of info but nothing specific, like which block and head combo is recommended or specifics like torque specs. I know this sounds dumb but im trying to learn so i can execute with as little trouble as possible. I also dont want to have to continually buy things because something doesnt fit or work right.
@@civicpride1986 where would you say is the best place to find information?
Any idea if this is possible if you have a electric steering rack so no power steering without having to swap to power steering
Great video brian! What about switching the r18 ECU for a SI ECU
Whoops didn't I mention that?
@@VTECAcademy Yes lol i had to rewatch it
What about K24 swapping an R18 9th gen Civic? Would this work too?
hello, would like to know what are the parts need to change to convert my automatic 2009 civic to manual transmission, can u share the complete list of the parts. my engine is r18
Hey, could you guys help me out with an ongoing conversation I have going about k series cylinder head compatability? I own an 06 honda element with a stock k24a4 bottom end in witch I have swapped a rebuilt k24a2 cylinder head from an 07 Acura tsx. It runs well and acompression test puts it at about 180psi on all cylinders. It is very common for posts to come up in the element groups about swapping tsx heads onto our stock motors but (finding this out after putting over 20k miles on my swap) it is common knowledge that there are issues with piston to valve clearance issues with a2 cylinder heads and a4 pistons. I have done some mild digging into old forum posts and have found info of piston to valve clearance issues but no evidence otherwise. So is my situation an exception to the rule or does it disprove the rule?
Ide love to k swap my daily but it's automatic. I wonder what would work to do so...?
I have a 9th gen r18 standard and everything to do a the swap but I am wondering if I am gonna need to change the dash harness or can I just use the r18 interior/dash harness
Please do or show what i need to do a k or B series swap in my beautiful red 02 civic ex coupe. They barely make nothing for this Gen n i hate they put a plastic intake manifold but atleast i got Drag Cartel Cam,valves lifters & retainers with full exhaust. What y'all think about supercharged compared to turbocharger on this single jingle. What would yall do besides saying get a ek or eg. I'm 37 had this car since a teen
7th gen? We got you! ua-cam.com/play/PL9Qq92QbHKki2X__tgKpf47lpyHyZRdV2.html
What I need for K20A Type R swap R18 powers 9th Gen Civic? I have a Honda Civic coupe 2012
He said simple and started naming off tons of parts.
Simple compared to a k-swap into an EG or EK.
Hello, any advise on which exact engine mounts id need for a k20a swap with a 07 civic hybrid or would i have to fabricate something?
Im sorry if i missed it in the video. But was wondering how much this swap cost complete. I see the mounts are like 700. I have an r18 lx and thought about this. But then came to realize that SI's around me go for 4k. Just wondering if maybe i sell the r18 lx and spend the extra 3k on an Si?
I need you guys to swap a 9th gen civic
Would this be possible with a 06 sedan? It’s auto so I’d switch it to a manual. Would I need any additional parts?
k24z7 oil pan will bolt up n need to swap tsx oil pump
Ok so I have a 8th gen civic and I did the classic k24/20 swap and I want to put a turbo 35r in but my si transmission won’t be good enough what should I opt for..?
Something about taking a man's pride in a sleeper Civic. Take both ihs Pink's and get 35 MPG on the way home and some road head
So R18 axle can handle 200+ HP? No fear of breaking it on hard acceleration?
Do you know if you can fit a k24a3 engine inside a fn1 civic type s mk8 euro? It has r18 engine
Hi, are you able to conserve ac with this swap?
Is this similar to a swapping a Acura ilx R20?
Interesting, I kinda want to keep my r18 forever since it’s my first car
Same.
I have a ‘10 ex Coupe automatic. Trying to k20 swap it. Do i have to transition over to a manual transmission?
Can you do a 2012 civic ex version 😅
Great content as always, however I'd like to know if you have some tips for us that are located in Europe, as any Si parts are basically unobtainable.
Driving an FD1 R18 Manual, and the most likely option for a K swap is a K24A3 from an Accord CL9.
Would I have to do really heavy modification of the wiring harness to match up the R18 to the K?
I'm guessing I'm also just using the standard ECU that comes with the engine I buy, as well as the axles?
Shifter linkages and a few other things are also a question mark since you say "just get Si ones", which I can not.
Any tips? TIA :)
Modifying the R18 harness would be significant. The stock ECU probably won't work. You could use the K24A3 engine. Could you get stuff from the FN2 Civic? That would be the ticket.
@@VTECAcademy Techically, I could get FN2 parts, yes, however they are quite expensive and hold their value very well, especially with undergoing global inflation.. we don't really see any part out's of the FN2..
It's a similar story as in USA of saying "just get an Si bro" 😅
So long story short, yes, and no, not really.
Accord's with a K24 are far easier to find and source parts for.
I was asking about the stock ECU of the K24, that should be able to work with the same engine, I'm guessing you misunderstood me and thought I was asking about the R18 ECU..
Could this swap be done on an auto? Please guide.
Is this information same as for FD1 chassis?
Seem as the R18 engine has become the modern day “D” series engine (the one nobody wanted until ebay turbos become a thing on them) and being so plentiful and cheap currently how easily would it be to put one say into a Honda fit as a super cheap engine swap? With a few parts and a tune I’m sure that lightweight eco engine should make a Honda fit a fun little back road racer on a budget.
Not really that much cheaper as a swap into something older than a K swap. You still need to take care of the engine management, wiring, mounts, axles, etc... We've found K24A1s and A4s for less than $200 that run at the yard which is at the lower end of what a running R18 goes for.
Is this going into an 8th gen civic? Is most this work for the 9th gen? Mine has electric steering :s
What would change k swapping a 9th gen
Is this actually worth pursuing as a DIY enthusiast?
Can you swap a r18 non-SI sedan LX?
Is this swap the same in a 9th Gen r18??
Out of curiosity, wouldnt the K20 oil pump conversion for the K24 have been easier to do than dismantling and notching the K24 pump for clearance?
I installed a K2.4A2 in my acura csx notch the type S oil pump & it works perfectly. No problems
How do I get one of those vtec academy hoodies
hello, a long time fan here =D
as swap around here in brazil still very expensive and It's hard to find the K20/K24 around here, I'll end up going for the 1.5t when the price drops
I have the r18a6 here in Brazil, and I'm trying to get the hondata to work with a US ECU in this engine, but apparently it doesn't have the vtec oil pressure solenoid.
Do you have any knowledge of how to get around this?
thanks for your attention
I don’t. Ask Hondata if you can turn that off in software.
So is it possible to convert an automatic 8th gen to manual?
Do you know if this swap could easily be done with an automatic car as well, you would just need the clutch pedal assembly?
Also guessing that there are no differences between coupe and sedan?
Yes, coupe and sedan are the same. You will need the brake and clutch pedal assembly. I haven't checked yet, but you may need to cut holes in the firewall too.
can I do this on 9th gen?
What about the body harness would it be able to read the tsx ecu or you used a si ecu ? Thank you
The Si ecu
I am currently trying to find a tuning solution for a K20Z2 Acura CSX FD2 Automatic [Paddle Shift]. Any Ideas if the K24 TSX Auto ECU [Which has Hondata available] Might be able to run your R18 Civic[w.K24A2] TSX ECU 37820-RL5-A51 I believe the ECUs are similar. Trying to find any tuning path for the 4 CSXs i'm trying to tune, eventually changing from Z2 Head to Z3 Head only after a suitable tuning ability with Auto K20 CSXs. Could you help me shed some light, really trying to narrow this down.
I wonder if the K20Z2 CSX [Civic FD2] Has a Factory Honda Rear Mount That fits where the Hasport One goes.
Oil pump from an rsx ?
So the r18 subframe work or did u have to use an si subframe?
We used the stock subframe.
What does something like this cost?
Would it be easier to get this civic with a manual transmission or can you do the swap with the automatic transmission
Would like to know the same as well if u got an answer
Quick question, is this swap a good idea for a daily driver? My r18 might be dieing and I would love a k series in my car but I would like to be able to keep A/C is that possible? Also has anyone made the wiring harness yet?
AC would need some of the hoses and compressor from the Si. Totally doable.
I want to do this for my 9th gen since it has an R18
I haven't bought one of those yet.
@@VTECAcademy I've been wanting to swap in one but the cost scares me away
Is this swap possible if you wanted to retain the A/T on the car?
It's possible, but we haven't explored that yet.
Was this an automatic lx before it was swapped? Were there holes to drill out for the clutch pedal?
I had to drill holes in mine
A customer of mine just gave me their 2010 civic lx auto. Thinking about doing this swap. How bad do you think the manual conversation is to do? I’m assuming it won’t be too bad
Hi, if you plan on doing this swap please document it if you can, I have a 2010 Civic Lx Auto and I would love to see the build on that. Would plan to do it if everything goes smoothly with yours possibly. The manual conversion shouldn’t be too bad as you would possibly need the clutch assembly, pedals, and he did mention you might have to cut through the firewall. Thanks
Hi I have an RSX from when I was young and I want to do a K24 into it how would I build a K24 into automatic RSX
Good question. We are looking into how to make a tunable AT compatible system fro those types of swaps.
