2006 Acura RSX Type S
2006 Acura TSX K24A2 Engine Swap
KTuner ECU
RBC Intake Manifold
Skunk Mega Power Header
K-Tuned Intake
That’s how a Honda is supposed to sound
Like how simple, and informative these videos are, subbed!
Excellent video. It proved the exact difference between those engines. Thank you
K24 VTC gang where u at? 😁
Appreciate the upload Nick 👍
WhenVtecWasCool heyy
😤😤😏
Here! Got one in a sleeper civic with a 6spd.
32° mechanical pin w/ DC Stg 4 cams-
awesome channel bro just found this on accident but i like what i am seeing here!
Dre's Racing Channel - Thanks! I appreciate that!
Awsome bro keep it up more dyno videos like this comparision is awsome bro 😁
I am also a DC5 owner! I can't wait to see the content on this project. SUBSCRIBED!
Same. But I'm base model😑
Right on, what i wanted to see. Cool deal.
Nice video, educational
Very informative mate
🔥🔥 clean rsx bro
Nice,I subbed as well. Good job!
Freaking car sounds amazing...
liked, & subbed. wnna see more videos of the rsx!
Awesome content
Hell yeah brutha!
It would benefit from a 50 degree gear because of the new k20 RBC manifold. Some k24’s even lose power with an RBC compared to the stock manifold without a 50 degree VTC. Great video! Thanks for sharing!
Leroy Dabbinzz I was thinking the same thing, I was gonna say it but I wanted to see if someone else said it first
Yeah I heard Evans tuning talk about that. Ps. Look up Gene kim n Chuck missler on CZcams
@@dochvtech22 lol This is motor talk bro, not christian scare tactics
What’s up guys so I was always scared to through on a rbc cause of your comment lol I thought it was gonna be the waste of the 400$ for a rbc I paid 230 lol but anyways I had got dyno tuned with just exhaust header and cai I made 213hp with 168 tq (greddy 2.36) exhaust and a dtr header, I went back to my tuner with a hks 65mm and a skunk 2 header and that rbc with a spacer to still use my stock throttle body, I ended up getting all that retuned and made 227hp with 185tq similar to what this guy made I just made about 10 tq more, so pretty much saying in my case the rbc did a lot for me , I made a bunch of more torque just cause of that , and during the tune we did a run to see how much I was making with the rbc untuned I made 220 right off the back, so you do make a tiny bit of power without tuning it but once you tune it you gain a bit more and a lot of more torque so getting it tuned helps a lot!!
Solid! This secures my choice with a K 24 swap
Rod Arana - you won’t be disappointed
Rod Arana if your going NA you Deffo want a K20A/2 head on there. Gains for days!
@@tuningbynick could you do a video with what parts are needed to make it fit
Need to do one with the 50* vtc and type s oil pump for research
My 2008 Honda Civic SI k20z3 intake header and a 3-in exhaust and Chinese knockoff 410 CC injectors port matched 70mm TB tuned on flash pro made 228hp
And that sir is why I bought a k24... another killer vid bro, I need to make my way out there in the future 🤘🏼
Gerb Productions you definitely do!
Bro great video and love the engine power comparison. Where do you have your shop to do dyno? I'm intrested.
just deserved yaself another sub. i have a 02 rsx base with a 08 k24a2 with a unknown header and RBC aswell and i been street tuning my k24 for a good 2 months now off and on because i sometimes catch my a/f get wonky sometimes lol im glad i came across this video. can you possibly do a detail visual video on cam angles in kpro whenever you may have the chance?
Thanks for the sub! - I can definitive try and put together a more detailed VTC video using Kpro
Awesome content nick. It appears low cam numbers are not really affected by vtc as much as high cam. Really interesting
DC WERX thanks! It didn’t make it into the video. But I did test out 10° in non vtec and it actually lost a bit of power.
@@tuningbynick great. Dont be afraid to make longer videos showing the ins and outs
Awesome vid nick. If you could in the near future before you go awd and turbo, plz do upload the 50 degrees VTC cam gear comparison with your current 227 hp stock setup. Keep up your good work and thank you.
I am definitely going to try and get the VTC gear swapped out as soon as i can and do a video on it
Tuning by Nick awesome brother. Looking forward to it. By the way it’s odd your RSX made more power in stock form than the ep3 k24A you tunes and dynoed. Just found that odd that’s all.
Law C - I agree. Not all engines are equal tho. This 06 TSX is super strong.
Hi Nick,
Just out of curiosity.. Did you measure difference between k24 and k20 oil pump on k24a2/3 engine?
I would like to know ho much power can hold balance shafts.
Thank you in advance for your answer!
The two lower cam angles towards the very top look like there about to make a run for if it had more rpm. Very interesting
ShredCulture it sounds like it’s got more in it you right
Which is better k pro or KTuner? I bought a k24a engine for my 02 type s and was wondering what ecu I should run!!! Please any help
Hey Nick, loving your videos! I have a k20 type R swapped mr2 spyder. But also have a k24 in the garage. I was always planning a K20/24 build. But is it really worth the hassle of assembling a K20/24 frank or should I just put in the k24 with 50* vtc and type R oil pump and call it a day? Will keeping the k20 head with the k20 cams give me that much of an advantage, of at all?
Did you replace the oil pump with type s as well or kept stock pump?
I can never find a good RSX in Toronto. Been looking for one 2005+ for the longest time (one that isn’t beat/rusted. The white looks amazing!
AfterLifeCA I actually found this one in Montreal
I've seen 2002-2004's in decent shape for around 3K, I'm thinking of grabbing one and throwing in a K24/K20. Checkout his guys build czcams.com/video/Cv4NjiG_rug/video.html
I'm not sure how but he's making over 220 torque with stock motor just cams.
oh nice, a fellow Hypergram DC5 owner lol... but your build is light years ahead of mine lol
Nice! I cant really take credit for them tho, the car came with them. But i do like them a lot
@@tuningbynick my K20 is still going strong but I'm convinced on going K24 once its time to swap ... perhaps even Supercharge it
TheRealTDawg K24 is the best bang for buck upgrade
What headers are you running ? I have a k24a swapped 06 rsx type s and I am looking into headers that will fit. Please lmk thank you.
So what do I need to do same swap to my 05 type s ? 06-08 tsx or jdm k24, and a kTuner? Do I need other mounts or parts to make this swap work ? I have a z1 now but might be looking for upgrade
I spent hours trying to search info for a K24 build.
Ive found the highest output "OEM" build is based on the following:
06-08 K24A2 block
K20A2 Head
06-08 TSX cams
RSX Type-S cam gear
Type-S oil pump
Type-S oil pan
I scoured multiple forums for this info and this has been upheld by a majority consensus.
Hope this helps anyone looking for direct answers like I was.
You can use a A2 or Z1 head. They're the same cast, the Z1 has the better cams, but it's been noted, as you wrote, that the TSX cams in either of those heads produces about an additional 10hp over the A2 cams, maybe 5hp over the Z1 cams.
Just wanted to update. I finally got around to getting a duno tune done with this setup. Full bolt ons minus torque damper, 245whp 198wtq
Whats all needed for this swap? I've got a spun barring and want a new motor..
Hey I have a 05 type s and I have k tuner but I haven’t got around to my 2 step what are the #s i have to put
Needs a 3” exhaust & cold air & then leterrreaaaat
Its getting a turbo kit soon!
Hey Nick, did you run into any clearance issues with the RBC and the hood closing? More specifically the sensors and hose on top of the RBC
I did with the k24a z1 head. I unfortunately cut it bro my hood. It's fine and functional, just not stock any longer
Thank you for giving all this info. I know it's a year later, but do you have a teat run on the 30 degrees? So we can see the difference. Thank you again for all the tests and info. Peac n love my man.
In-depth video on the vtc install please
I dont personally do much install work these days but i'll see what i can do. In the meantime. Check out my friends channel - Speed Academy - They have great video on that - Heres the link czcams.com/video/txvwWJmxB3U/video.html
Do a video on vtc tuning
Have you done any testing with the stock tsx intake manifold vs the RBC? Hondata shows a loss in tq but your graph looks awesome. I'm doing this swap and trying to decide if its worth adding the RBC, thanks!
I remember hearing that claim long ago - All the K24s ive tuned had the RBC so unfortunately i haven't been able to see how the stock one performs
Interesting
Did you use the stock oil pump or did you use a k20 oil pump with the balance shaft delete?
Nice combo will hit you up when I get my k24 type r up and running ivd got a basemap 👍
Its still got the stock K24 oil pump - Thanks! Hit me up anytime!
So you are telling me that all stock k24a2 is making that to wheel? Dang im getting mine tune right now!
What exhaust is this? That shit sounds so good
Where did you get the megapower header?
what front spiltter do you have?
Hi Nick with your power figures are these at the wheels or flywheel?
Where is a good website to buy engines?
intake header and exhause it stock? wow everyone stock now days then,
Nice, k24 swap in everything and everything hahahha. We have one in our Mitsubishi. Love that motor.
Sleep R Garage - K24 in a Mitsubishi! That sounds cool.
@@tuningbynick yeah check out our channel
@@SleepRGarage you’ve got another subscriber!
Thank You Sir
@@browhyareyallsobad8673 thank you 🙏
Baby steps!!! Next step is k20 head
Aren’t you supposed to swap over type S oil pump & plug an oiling cavity under the windage tray to avoid loss of oil pressure and cavitation at higher rpm?
The Type S pump is better and yes i think that is definitely a good upgrade. But i have had no issues running up to 8000rpm on the stock TSX pump
Wheel specs? The car is beautiful
The higher angles increase overlap and help with scavenging until very high rpm where the cam angles may want to be retarded to take advantage of the air inertia and the ram air effect. If this was a turbo application I would expect less cam advance in the mid range due to backpressure from the exhaust system. The k24 and k20 share almost the same bore only the k24 has a longer stroke making it undersquare. The k20 may rev higher but the peak torque figure would be less. The k24 may make more torque but at a lower rpm. Thus, both engines can have roughly the same hp but their torque figures can be quite different. If the k24 made its peak torque at the same rpm as the k20, the k24 would make more power mathematically. However the K24 being undersquare, limits the maximum rpm lower than that of the k20. Also, the K24 head is designed to be most efficient and operate at a lower rpm, thus any larger increase in rpm may net a decrease in torque. If you can safely get the k24 to rev like the k20 then fitting a k20 head to the k24 may be beneficial.
you prolly dont give a shit but does anyone know a tool to get back into an Instagram account..?
I was stupid lost my login password. I love any tips you can give me.
@Nicholas Titan Instablaster ;)
@Hugh Zev i really appreciate your reply. I found the site thru google and im in the hacking process now.
Looks like it's gonna take a while so I will reply here later with my results.
@Hugh Zev it worked and I actually got access to my account again. Im so happy!
Thank you so much, you saved my account !
@Nicholas Titan no problem :D
JDM k24a2 のREV Limitは7000rpmだけど、どこまで安全なんだろう？
バルブスプリング1本だからDC5のスプリングに交換したほうがいいのかな？
Anybody have interesting knowledge to share regarding supercharging K24 or K20/24?
you should do a comparison with k24 bottom end and k20 head to see if its worth swapping the heads
There been videos by other people on this, short story is a k24/20 Frankenstein motor is not worth the extra 30 whp or so if you plan on building the engine/ boosting.
Tien Tran so it’s not worth getting a type s head for my k24a 200hp ?? But if I plan on doing a he’s package is it still not worth it ?? Thanks
@@TienTran-kw3il not worth 30whp? Those are huge gains for a head swap
@@TienTran-kw3il Where can I find those videos? I can't see 30 WHP just from swapping a K24A2 head for a K20A2 head, that's about the gain you'd get from swapping a VTEC-E head to a true VTEC head such as a K20A3 to K20A2 head swap.
I’m thinking of going to the K20A2 head and K24A2 buttom but what pistons should I run that will be good for boost
10:1 compression pistons are usually the best all around pistons to go with
What did you need to do to put the Civic Si trans in your rsx? Thanks!
Matthew Trudeau - I technically didn’t do the work. But as far as I know. The only change was swapping the shift selector in the trans from the Civic Si one to the RSX one.
I noticed you are using the Rbc map sensor, did you block off the sensor on the throttle body?
The sensor on the TB wasnt reading correctly after the swap, i think it was partly blocked of by the gasket. It was just easier to use the RBC one
Need that K Pro broski
Isiah Elliott keep watching the series. It gets a Kpro.
What kind of wheels?? Specs??
Me: idk what 50 degree vtc anything is lol
that's really good for a stock motor..
i spent bunch of money and tears in my B18C5 to make about the same. T_T
Did the header had any clearance issue? Was told you cant use k20 header on k24 engine
- The header hit the front sway bar - So i had to remove the front sway bar for now. That was the only issue
Dope awd rsx
My rsx has a k24 and sound the same😏😎
What ECU are you running??
Hey I just put in 07 tsx motor in my type s, similar bolt ons like yours but the next step is for me to just swap out the type s ecu and get kpro v3/v4 or Ktunner, any big differences between these ecus?
Anthony Mirsoane - Is your car 02-04 or 05-06
Kpro is a lot easier to work with. But if your car is 05-06. Ktuner is much more economical
Tuning by Nick hey 02-04 so I guess kpro is the route I’ll be going then , thanks!
Did you do anything to the thermostat housing? The tsx faces up and rsx s is down. Just wondering, I'm doing a k24 build on the rsx to but I'm stuck on that
I transferred the whole thermostat housing over from the RSX and used the RSX thermostat
@@tuningbynick nice, did you get any leaks after from the top hose after changing from the rsx?That one that has the seal ring
Do you know the specs of the "jdm" k24a motor? My local shop is having a sale and im thinking of picking it up. And also, would the skunk2 alpha header fit on the k24s? thanks!
The Skunk2 header fits - But because the K24 engine is taller, it raises the header up higher and it hits the front sway bar. I had to completely remove my front sway bar for now. Unfortunately i dont really know anything about the JDM K24A
Tuning by Nick thanks!
What changed happened to the harness with the swap, and are you using the type s transmission?
The only change to the harness was repin the crank sensor because the pinout is different. I actually had an 8th gen Civic Si LSD transmission in the car at that time
Where’d you get that intake piping?
I used left over 3" intercooler piping - But K-Tuned has piping 3" piping just like it
K24 > K20. The K20 is better suited for boost with a higher redline , less compression and make more top end on boost due to a better flowing head however the K24 on boost is better balanced between torque and horsepower if you want more torque.
Broooo that’s what’s up just finished my swap and it’s way better than the damn base! Anyways how can I get that base map bro haha
- Shoot me an email and we can talk - nick@tuningbynick.com
@tuning by nick I just emailed you
stock oil pump? couldn't see what you rev to
Yup - Still stock oil pump - Currently redline is at 7700
Is there any reason you didn't go with the k20 head + k24 block hybrid? What kind of power do you think you'd make with a K20 head?
The TSX head is nearly as good as the K20 Head - At this power level the K20 head wont actually make any real difference - The expense of the K20 head would not be worth the minimal if any HP gains over the TSX head
@@tuningbynick be sure to dyno the heads back to back and report back......please
Does anyone know how the 06-08 TSX cams compare to the JDM K24A cams? Is it worth spending 300 bucks on used cams. Is the increase in power even negligible?
Yes. Can someone answer this… did you end up getting an answer??
@@jeferainman2990 I can answer. The exhaust cam is the same for both. The 06-08 TSX intake is better than the JDM intake cam, though not by much.
@@jesselee4405 hell yea thank you for the update. I’ll prob just get the skunk2 drop in cams or drag cartel. Thanks again
Same transmission in both cases?
Manuel Jimenez - I guess I forgot to mention that. But yes. Same transmission. It’s actually got a 06 Civic Si transmission in the car.
Nice video... Is that wheel Hp or flywheel Hp?
This is wheel HP and no correction factor
@@tuningbynick Cool... Impressive power well done on the tuning
Marcellino Munsami my k20a2 with RBC 4-1 manifold and 2.5 inch system pulled 221 WHP.. the k24 has a lot more it can gain in an NA form just from a K20 head or VTC gear with better cams!
Now put the K20 head on. The TSX head Vtec sux. And low redline. If you want more torque and not lose Vtec but have the best of both put the K20 head on the k24 block and your running a monster bottom end with a monster top end! ..Do It!
JoWaY - I sold the whole K20 engine. TSX heads are not bad. They flow nearly as much as the K20 head. The lower redline is because of the rod stroke ratio. Not any limitations of the head.
any problems with the header ? with the k24 being 19mm taller ?
cam - I had to remove the sway because of the header
The sway bar is always a problem
What’s up bro I got a rsx base I was planning on swapping it to k24 but does it matter which one I get? There’s one from crv and one from tsx I think and does year matter ?
Tsx 2008 up.better internals.
2006 up right?
What header was used with the k24?
Skunk mega power header
bhadz100 Skunk2 Mega Power.
I'd say it would benefit from 30~32 ° VTC . Usually if a K sees an increase at the max stock 25° it will benefit from the 50° gear.
I've had a K lay down the 250's @7800 @ 35° VTC
Agreed - This engine can definitely benefit from the 50° gear
Do you etune?
4:40 what it made
I have a question what clutch stage would you recommend for a k24 turbo making 300-350hp
Spooling Nation - It really depends which brand. But usually stage 3 and up is what you need for a boosted setup
Competition Clutch Stage 4.
Spooling Nation anything under 400 an exedy stage 1 holds fine and is easy on the trans I know from experience
Dudehoolikesairsoft thank u🔥👍🏽
Tuning by Nick what’s your IG and FB?
what Air fuel numbers under WOT do you aim for?
Moses Moonsie 12.5 afr is the target for full throttle
@@tuningbynick thanks for the response.
K20 all day
how is 227 bad when a tsx only produces 200hp? that's actually very accurate, did i miss something?
Josiah Butler - I agree, think the results were very good.
Tuning by Nick i was making sure i wasnt tripping, 227 off of those simple kods is correct, its a k24 they made more numbers than k20s
@@josiahbutler2254 yeah it’s good numbers . The dyno reads hp to the wheels so if we’re talking about crank hp that dealers use to advertise their cars, 200 hp from the stock tsx to around 255-260 hp (227 hp to the wheels) is very good for basic bolt ons and a tune. 40-50 hp gain from those small things and a tune is what makes the k series engines great
What’s the name of those wheels?
jose torres they are Konig Hypergram wheels.
would it make a difference to throw a k20 head on top of that k24?
The K20 Head might make a bit more power with these 06 TSX cams - But I dont think the cost of swapping the head would be worth the minimal gain
What exhaust?
Kevin Ly - it’s a custom 2.5” straight through exhaust. It’s not a good one tho. Lots of bad joints/welds in it.
what lip is that on the front? looks great.
Hunter Johnson -It’s actually that stick on universal stuff. Like this stuff. www.amazon.ca/Original-EZ-Lip-Universal-Spoiler/dp/B009F10S3Y/ref=mp_s_a_1_3?keywords=universal+stick+on+front+lip&qid=1573698720&sr=8-3
Is it hard to put a k24 on a rsx type s?
star dust - It’s not a difficult swap. Pretty straight forward
@@tuningbynick I have done all my work on bserious but nothing on k's
Or you can get best of both worlds and do a k20 head and k24 block
I would love to try that combo - I sold the old engine tho, so i dont have a K20 head anymore
