K SERIES HUGE INTAKE MANIFOLDS...MY EXPERIENCE
Вставка
- Опубліковано 21 лип 2024
- This is just a run down of my experiences and testing that I've done with the large plenum intake manifolds on my K24 engine and my conclusions I've come to that help me decide what route to take when dealing with naturally aspirated power.
The intake manifolds shown in the video are the K-Tuned side feed intake manifold, and the Skunk2 Ultra Race center feed manifold Descriptions listed below.
K-TUNED:
The K-Tuned Intake Manifold features a very large 4.78L sheet metal plenum shaped in the signature tapered Magnus format. If you look closely at the plenum base and the TB flange, you'll find two custom 6061 billet aluminum pieces that are precision machined using a CNC 3D profiling process. This special CNC process is what ultimately helped make this manifold design possible, allowing us to make the necessary multi-axis CNC cuts. The 90mm throttle body flange matches up perfectly to the plenum and is tapered inward to ensure there is no restriction to the incoming air. The throttle body bolt pattern matches up to the 86-93 Ford Mustang 5.0L specs, which means our K-Tuned 90mm Throttle bodies will bolt up seamlessly. The custom billet plenum base is a work of art, with four precision machined internal V-stacks that are designed to increase runner entry air speed. We also provided 3 x 1/8 NPT vacuum ports that are neatly tucked away on the plenum base, and positioned between each runner. The runners themselves, measure 5.75" long with a large diameter of 1.875", and are capable of supplying even heavily modified K-Series engines with plenty of air. The manifold flange at the cylinder head is available for K20 and K24 heads and is another 6061 billet piece, that maintains proper port entry and injector angles. Included with our manifold is a brushed aluminum K-Tuned Fuel Rail, which is held in place on a rail mount that is designed to keep the stock phenolic fuel rail spacers in place and accept both stock or aftermarket K-Series fuel injectors. As usual, we include all the hardware, specifically the bolts for mounting the manifold to the cylinder head and the 4 bolts for our throttle body. Last, but not least, we placed an aluminum K-Tuned badge on the front of the plenum to add a nice finishing touch.
SKUNK2 RACING:
Ultra Series Intake Manifolds are made from high-grade 356 aluminum alloy for a strong and lightweight design, CNC-machined for a precise fit, and individually inspected for quality assurance. The large 90mm throttle body opening, 87mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, high-horsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level affordable high-end intake technology to the marketplace.
FEATURES:
Available in 3.5L (4.5L and 5.5L configuration require the purchase of optional spacers)
Optional Billet Aluminum Plenum Spacers in 1L or 2L sizes
Hi-Grade Mounting Hardware
6.5” Tilted & Tapered Hi-Velocity Runners
Raised 87mm Velocity Stacks - Plenty of Material to Port
Provisions for additional injectors on bottom side of runners
90mm Throttle Body Flange - Std. 5.0L Ford Pattern
4 x 1/8” NPT, 3 x 1/4” NPT and 1 x OEM IAT Port

Great comparison, your builds are so bling and polished up show car status. You have excellent style it's all art to perfection.
Glad to see more uploads from ya. Looking forward to the coupe rebuild
Really appreciate you going into such detail comparing the manifolds.
great advice, gotta take into consideration engine volume,air flow etc when choosing a intake manifold. that's why i still have a rrc on my k20a
Keep making vids, I like your presentation style. Nice garage !
Love both products but like how that k tuned one looks on your engine bay, thanks for the info, keep it up.
man great video have watched a few of your dyno videos and car videos but this one made me subscribe. beautifully built hondas man. just got into hondas about two years ago but cars are my life. I own a 97 ek im building full function 7 rear subframe brace and lcas cabing full front bracing skunk2 camber plates, and oem ctr headlights tails and lip kit with spoon rear wing. also trying to start on my 08 si sedan. but good parts take time to afford. thanks for the insight and knowledge it really helps. great things will happen man maybe not tomorrow but it will happen. try to stay focused and don't get discouraged. more videos like this one would be cool. keep it up.
that engine is polished to the max looks badasss man great job
+Randy SD and thank you dude!
Good run down between the 2 manifolds and just take your time you will get the car done I saw myself in several situations were I wanted to give up and sell my ae86 coupe but I got it running after 3 years of work and a lot of headache and frustration so I kind of know what you going through at the moment but you will finish it I'll give you my best and keep the videos coming
+Joseana Diaz thanks for the feedback. Good words. Yeah I'm definitely sticking to it.
Good to see the vidz coming, it dont matter on what
+Seven Castle thanks man. I'm trying
@@ksisjdm @7:00 " me I'm not really picky about my stuff" funny bud funny... Coming from the guy who's engine looks cleaner than a dish I get out of the cabinet... Always did and still do love your videos I'm still watching them I guess I forgot some a few years ago and needed a little advice! Thanks you always been a big help in the Honda Community! 👏👏👏👏👏
First vid I watched of urS def gonna tune in to ur channel subbed
+Irvin Dorsey thank you dude
New to your ur channel young blood. Good job man, the production is A1. I'm gonna subscribe. I'm new to this honda stuff and I'm trying to learn all I can.
Thanks homie. I appreciate ya
Love your setup👌
TRUUUTH!!! I did some research on IM a while ago myself when I was looking for my next bolt on and that's exactly the result I found. Without a good supporting bottom end you just have a big shiny manifold w/ no power gains because your car can't breathe in strong enough to use it. Good work bro!
John Hayes bottom end? I thought you needed cams and porting to make use of the intake manifold. What would a build bottom end do for it? Just wondering man. I'm looking into building a motor
+David the added displacement and larger bore helps a lot, as well as increasing compression. A bigger bottom end as well as a head would be much more beneficial than trying to make use of these large manifolds with a small 2 liter block
Childstar makes senses now. Thanks!
That k tuned mani looks dope tho. Way nicer looking than the Junk2.
Love magnus manifolds I have one on my Dsm
Been a long time since you uploaded brotha, glad you did!
+LATOMMYLA yeah, been broke and with the car apart. I have no motivation lol
I feel yah man, take it nice and slow!
I have a new-er JDM K24A RBB3 motor I am swapping out my K24/K20 with. I have had the motor in my engine compartment for 2 weeks... Just need to install my IM and coolant lines, but it has been 115 degrees for like 2 weeks so I have just been sitting on it LOL. Childstar do you know of a good place to get Hondata maps? I have tried K20a, CRSX, and the Hondata forums but no one will load their maps for some reason...
+sbounty3 no I don't know any place to get calibrations. Most won't load theirs because of the price it cost to get their car tuned properly in the first place.
Excellent information bro👍
Good info man! Thnx a lot again
came from honda street garage , subcribed ! good vids 👍
+DeeBoyy 16 thank you dude! Much respect to you and Mark for shouting me out!
Cool video bro, great info!!
+Christopher Pollard thanks for watching man. I appreciate it
digging the video dude, only thing about the fi comment is that a better flowing engine will make more power at a given boost level. so every detail does count, more so when racing at a competition level. keep em coming thou
+TheDrtye I was referring to the larger manifold designs for forced induction, the solid large box designs still flow extremely well under boost but perform like shit naturally aspirated. So with boost, a large volume does the job, whereas all motor, the deisng needs to be much more specific
+TheDrtye and thanks for the feedback dude and for watching
sound advice, superb video
Keep up the great job man, you make videos that not all Honda Utubers make... 💪
great video brotha, people need to do research on everything before you build, tune, buy ect anything but you know this... #FinePrintKills
Really good info 👍🏽
Nice built 👌🏾👌🏾👌🏾

Very close lol, good stuff man
Finally new video 🤘🏼😎
+JONATHAN ZEPEDA and the other couple of new videos, yeah lol
Giving them that knowledge !
What's that coolant reservoir next to the fuel rail cap off on the right side of your intake? I've seen coolant bypass plates but never anything with a rad cap like that.
That's the water neck for my coolant system. Since I use a tucked radiator that doesn't have a direct fill point, I use the water neck to fill the cooling system and it also serves as the highest point for easy bleeding of the coolant.
Ha I've been racing for over forty years and I/we always send the Manifolds out if they are all shiny and smooth to be Sand / Bead blasted with the coarsest Sand to improve the mixture quality. Proven on the dyno a lot of times. Even Maniflods with varying roughness will be sent out to even out the 'pattern'. That is a part of why the hp figures were down on the Skunk. Another reason the difference in Air Speed between a Side Entry vs Centre Entry. Side Entry will usually be higher regardless of Volume. Then there is the Reversion Factor. ....... It just keeps going on and on...... Even before I saw your results I had money on the Ktune. Next time may I suggest you make the Manifolds the same design. But it was interesting to read up the difference you found between the two designs in a NA application. The DC5 I race has TB's with a Toda
Side Mount Plenum.
Well in all your forty years you didn't realize the skunk2 manifold is actually cnc ported and has a textured finish that simply appears smooth and there's been dyno proven results via 4piston documenting the improvement over stock.
Another thing, the test consisted of BOTH SIDE FEED VERSIONS OF THE MANIFOLD. So the smart remark suggesting the manifolds be the same wasn't warranted. The skunk2 centerfeed didn't even exist yet when the testing was completed.
Another thing, if you look at the graphs posted from each engine with their respective back to back results, you can the see the skunk2 manifold start to gain ground and hold power at very high rpm just like its item description for usage for NA engines. The average user of this manifold doesn't build such a high rpm screamer, but some of the dedicated drag NA cars do.
I even referenced that items used in the video because I know how people look at the video image and don't listen to what's said.
Thanks for watching and commenting.
That motor is so sick bro. Dam.
Thanks man
it looks nice brotha....
I didn't know Lavar Ball did cars too! LOLOL just kidding man, love your vids
I might just port my 05 TSX (K24) manifold, running full bolt-on with ECU upgrade next.
I have a question since he have similar set ups to your first one stock 06 k24a2 which I have in my rsx with a 50vtc do you think its worth porting out rbc manifold on a stock 06 k24a2 head since I hear it doesn't have good air flow it ain't worth doing cause I'm debating on going ktuned 72mm tb soon or 80mm ktuned tb
+Henry Parada if you've seen my results with a 80mm on a stock internal tsx you'd see how well it does all flow. The tsx head can flow plenty air as well. Just because it's not "as" efficient far above 8k rpm, doesn't mean it doesn't flow well. There's more to performance than the peak hp number.
To your main question, I do not think the rbc needs to be ported to perform well with your setup. A stock port rbc manifold can support a lot of horsepower as is. Porting it with a stock internsl bolt on engine, typically only gives any noticeable gain at a high rpm. That's a costly service for minimal gains. Port matching the TB, yes, but porting the manifold itself, not so much IMO. The way the manifold is ported makes a huge difference as well. If it's ported too big, it has the drawback of slowing air velocity and sacrificing midrange in favor of high end hp. A very good port job could potentially make gains throughout. But without a cnc port, consistency on porting is a shot in the dark.
Beautiful
word Bro! good job....
will a center feed intake manifold typically deliver air at a equal rate into each cylinder through each runner? (assuming ever runner is exactly the same length and shape).
At an almost equal rate, more equal than a side feed manifold will but less equal to individual throttle bodies of course.
hey man love your vids man been watching a long time. i got a question what sub frame are you running i got a k20a2 swap im doing in a 97 ek and really wont tobrun ekk2 mounts but haveing a hard time finding a eg subframe thanks in advance bro keep doing your thang.
+Joseph Merriett thanks for watching man!
I have a eg/dc subframe. They are the exact same. So that should help with finding a subframe. The front lower control arms are what's different between eg/dc because not all of them have the spot for a sway bar
Childstar thanks man i told my wife i was gunna take her gsr subframe she told me to unsubscribe to u.lol it was just a joke but thanks my dude
+Joseph Merriett hahahaha brutal lol. 🖒😅
good video bro
Have the same ktuned very nice
So would you say it's better to run a ported rbc manifold or a skunk2 pro series with a supercharger over trying to run the k-tuned side feed with a supercharger? The engine i have is the k20z3.
If it's between a ported rbc and a skunk2 pro series...I'd go with the ported rbc.
Now if both the rbc and pro series was ported, I'd recommend the skunk2 pro series. Being boosted, you can take advantage of the larger volume of intake air.
Thanks for the info
weird I was unsubbed somehow and never got the notification. Sweet video as always, gotta compare kinsler/twm/obx itbs next haha.
+Garrett Bodrogi yeah I had another two people who said they got unsubbed too. UA-cam is all jacked up.
And hell, there's no comparing those 3 Hahah, kinsler is in a league of their own. I do have access to a set of 64mm kinslers though. Nobody I know uses those low end ITB's
@childstar
Quick question bro, not much info from people that have actually had these manifolds. I want to run ac therefore i have the ep3 style pulley. I know i gotta modify the waterpump housing, thats no problem. Any of these centerfeeds can work with my setup?
The mounting point for the ep3 pulley has to be cut off in order to run these manifolds. Ktuned has a post mount bracket with holes that allows the ep3 pulley to be further offset, but i do not believe AC can be fitted with it, but I know its possible to retain the ep3 pulley setup using that post mount bracket.
@@ksisjdm thanks for the reply my dude!
Are you deleting ps? I'm trying to keep mine using the k-tuned centre feed even though it says an ac/ps kit must be used.
Hoping not to have to use electric ps pump from mr2.
Where do you get, or find this k-tuned intake manifold, any for ep3 k20a. Would love one specially made to fit the ep3, as alot off aftermarket intake needs a bit off trimming for fitment... ??
It's a ktuned intake manifold, I got it from ktuned.
No there isn't one specifically made for an ep3, so you'll have to do like you mentioned and work with it to make it fit most likely.
Thanks brother.
So...
Witch one generates more power?
Also?
What size throttle body do they both require?
What size holes too?
I showed two sets of dyno sheets, the ktuned manifold made more power overall and more power on average. The skunk2 ultra race manifold started to pick up on power and close the gap in power around the 9000 rpm point. If you have a setup revving higher than 9k, the skunk2 ultra may make more peak power while sacrificing midrange and low end power.
They both use a mustang not pattern for throttle bodies and the manifold entry size is equal to 90mm.
@Childstar, the dip stick on your engine is it a cover or is that a whole different K-Tuned dip stick?
It's a ktuned dipstick
@@ksisjdm Yo, I'm goin K-Tuned also, I like the K -Tuned exhaust too, a lil loud but I think it sounds good
I have far more than just ktuned on my car. Most people don't pay attention to my build and only notice the big shiny stuff. Dont settle for one brand. A bunch of companies have badass products
A+ video
+Clint Eastwood thank you
but I'm finna watch them now. your videos are the shit. I learn hella and your not boring as fuck. so i fuck with you bro
What is the other intake manifold you have on that motor. It’s hard for me to hear the name. Could you provide the link to where you got it? . It sounds like it’s a good choice to go with. Why do you recommend it? I’m building a k20/k24 build.
I have a K-tuned intake manifold and the other is a ported Skunk2 ultra race intake manifold.
Love it! Even after all these years, I still come back to watch this clip! Lol
Just a thought that I’ve always wonder,; with the power that you’re making with the manifold, was it just a bolt-on KTuned Side Feed? No porting or so ever?
Reason I asked is because everyone seems to be running either ITB or a 4Piston SK2 Ultra Race 5.5L/90mm.
If the KTuned Side Feed doesn’t need porting and just a direct bolt-on, in my opinion I think the KTuned would be a bettter price considering it comes with the rail, no porting, and the *bling *bling making big power .. lol
Any feedback would be greatly appreciated!
Yes the ktuned manifold is directly installed with no porting at all. And yes you make sense with your assumption. Down side is its currently harder to get ahold of the ktuned manifold versus the others. The skunk2 manifold with the real and larger spacer is much more expensive but it also still has room to be ported even bigger for true huge power cars that need that. The vast majority of builds don't need such a massive manifold but people just copy what they see rather than use what would suit them best.
@@ksisjdm Thanks for responding back Kerry, I appreciate it! Everything is knowledge as you watch, learn and test.
But on your last statement in regards to the SK2 Ultra Race, I totally agree with you, it definitely leaves more room for more power with the 2L spacer and port, thus why SK2 purposely made it that way (room for improvements) if needed.
As for the KTuned, it’s a direct bolt on that makes good power exactly the way it is with a setup like yours 24/20.
Thanks again Kerry, wish you all the best on your build! Much Love 💯
The part of leaving more room for improvement is VERY DECEIVING though. People need to understand when and where that manifold makes power and performs its best and the honest answer is, it's in an area where the vast majority of people won't ever use or build their engines to.
They speak of this in a very subtle way in their disclaimer for use. Most people aren't building engines that see the bulk of their power above 9000 rpm and closer to the 10,000 rpm range. Everyone is lead to believe bigger is better but that's not the case. Especially with Naturally aspirated setups. Balance and harmony is beyond important.
That's why I spoke of the two engines types we used and the rpm range and you can see closely in the graphs the skunk2 is just beginning to shine extremely high up. There aren't a ton of 10k rpm street cars running around. The skunk2 ultra side feed that was used was already cnc ported and even used with a head perfectly cnc ported to match it. Increasing the plenum volume will have hardly any effect with all motor because the engine isn't flowing air more quickly than the plenum can hold.
It would take an extremely large about of forced induction to max out that plenum volume. So considering the plenum spacers as some benefit is a mute point. The runners being ported does make a good difference, but the larger the runner volume, the lower the air velocity unless several other things are done to compensate for the slower air entry speed.
They say a rough finish aids in fuel atomization on the intake side. Do you think sanding it clean or leaving it rough really makes a diff? Maybe that only applies to the runners themselves.
+Ryan Riffs yes that's true and yes it pertains to the the area where the fuel is entering which is at the head rather than the intake manifold or runners. Those cnc ported heads actually help with it as well. Even though it feels smooth by hand, the cnc edges help with atomization.
+Childstar cool man that's what I was thinking too, inside the head around the valve stems. I replaced my valve guide seals yesterday with the head on. Worked out awesome, running a b16 ATM. Nice vids dude.
Yo very informative
When you cut off the pcv did you block it or leave open ?
Both.
Left it open until I had my valve cover with more spots to vent air from. Once I had a couple of lines coming from my valve cover I blocked off that port
How's your k tuned Hall effect TPS holding?
+Aries Robillos I have it in a video a little newer than this one and it's still fine. Been using it for years now.
Did the fuel rail come with the K-Tuned manifold?
+Orichino 714 yes it did. Ktuned supplies the fuel rail with theirs
*What Kind Of CAI Can I Use For The KTuned Manifold And 90mm Ktuned T.B?*
A 3.5 inch to 4" diameter intake for smooth air entry into the 90mm inlet.
Childstar *Hybrid Racing 8th Gen works?*
Dude, just get some piping in the size you want. There's so many variables to different chassis and the use of the car. An intake that "WORKS" is simply any properly sized piping. Even too large or too small of piping "works". There's no off the shelf intake created for big manifolds. Use whatever you see fit.
Question.. Did you Ditch the RBC because you couldn't get to 300whp? Asking because I ported mine all the way out ports & TB port fully, looking to get 300+ with DC3.2 cams
No, I never gave a damn about reaching 300 whp. I made changes out of curiosity and for testing. To get real back to back tests done to see what really makes a difference on my engine.
TerryT Garage if you reach those goals please give us an update.I've just imported a K24a2 TSX to the UK (expensive ballache) and I want to acheive 300bhp with it. Everyone keeps telling me how expensive it's going to be,like I didn't already know. I'm looking at 12:5:1 Wisecos and stage 2/3 cams, but I'm a bit lost after that.it'll be my dd
My car is already at 300 whp on 93 pump gas. Had this output for years
Childstar yes but did you have 300 whp with RBC on still?? Or not untill u put the bigger one on??
I have a video covering that. Every detail. It was after switching to the big manifold. Still doesnt mean it requires it. The overall combination of parts is what matters
how much you want for the forward facing manifold? im ready to buy right now
+Ramon Garcia lol... the skunk2 manifold isn't even mine. If you're ready to buy, hit up skunk2, jhpusa.com, 4piston or any other vendor.
what camera you use and editing software bro?
+jmont124 typically I use my cell phone, Samsung galaxy s7, a gopro hero4, and sometimes a Sony a77 dslt.
Editor is just Sony Vegas home studio. No pro version or anything
Childstar thanks man! sick editing
what brand of coilovers r u running?
+Randy SD Ktuned K1 Street right now.
oh ok cuz i saw yur suspension is tight thats damper right and height adjustable?
+Randy SD yes sir, adjustable height and 32 way dampening adjustment.
Man did you test the Skunk2 Ultra Race Centerfeed Manifold? & is it ported to by 4piston? I never head that you mentioned it on the dyno back to back test that you made..
I didn't test the centerfeed one because someone already did a back to back of the skunk2 ultra side feed versus the skunk2 ultra centerfeed and the centerfeed version did worse than thur side feed.
@@ksisjdm woah! all along i thought that the skunk2 ultra race centerfeed is better and can make more power because it has a larger plenum volume (5L Centerfeed vs 3.5L Sidefeed) than the sidefeed one..
@@ksisjdm it might be interesting to see a back to back test of K-Tuned Sidefeed & K-Tuned Centerfeed + a Skunk2 Ultra Race Side Feed ported by 4piston with A 2L Spacer to add more plenum volume.. i wonder which one can make more power out of the three that i mentioned..
Just because its bigger doesnt make it better. The skunk2 ultra race already really needs an engine that operates best closer to 10,000 rpm. Increasing the plenum volume slows the air speed down quite a bit which isnt beneficial for all motor.
The ktuned side feed already out did the skunk2 side feed that was ported by 4piston easily. The ktuned centerfeed is the same design as the ktuned side feed just slightly bigger plenum an center positioning, so the 2 ktuned manifolds perform similar to themselves. This is a no brainer comparison.
Clean engine; Pure sexyness man! Do you know if the K-Tunes manifold fits a k20A on an ej8 (2000 civic ex)?
+Nahun Flores yes it fits.... look at my car, you can clearly see that it fits. 🖒
Childstar yea I saw that man and it looks GOOD! I just wasn't sure if you had to like cut or modify the frame or hood for it to fit.
can someone please tell me what is that part to the right where he is unbolting the intake manifold at 4:17?
A k20 upper coolant neck.
Childstar if I send you money via PayPal, could you post parts to me?trying to avoid customs charges etc. Lol I just imported a k24a2 to the UK because I saw one going for a good price, but by the time it got here and I cleared it ,it wasn't such a bargain anymore. I'm starting my 300whp dd build and like the look of some K-tuned parts,but I don't wanna get stung all the time by customs n duty. Your build is 🔥🔥🔥
And what benefit would I get working and shipping parts to you?
Childstar Wooooooy, maybe helping a struggling UK niggah out man!? 😮 besides,I only really meant like the manifold,once I saved up for it. It's cool,all the best. 👊🌚
Sorry it's not like I have money to help out. I hardly can do anything for myself
Can this engine be modified K24Z1?Honda CR-V 07
+Oscar Deleon yes
Childstar ok thank you
you like them i have the new skunk 2 ultra center feed .
+Sean Kaine I do not like the skunk2 manifolds for my engine. Robs me of power for my whole rpm range from nothing to 9000 rpm. I just wanted to show how it compares visually and some specs of it versus my manifold
why didn't your header have the v band on it in the beginning.?
+Tyler Sanderson this is the second ktuned big tube header I've owned. I haven't put the vband on this one yet.
Childstar ahh I gotcha.. sorry for the questions I was like damn how's he have it bolted up without it lol
+Tyler Sanderson Hahah yeah. I've been redoing like everything. I had a hanger break on my exhaust and it dragged on the ground when I was far from home. So I got new piping, a new muffler as mine was melted against my rear bumber, new rear bumper, and sold my header initially but then picked up another one. Ran it open header a few times but that's enough of blowing my eardrums out lol
Childstar yeah I hear that.. I just bought that header yesterday and gonna swap everything into my coupe real soon.. love your attention to detail.. it's bringing mine out as well
I like the shiny one
Can you run ac and ps with centerfeed intakes?
Yes, but the requirements and your approach to retaining AC and PS will vary based on the centerfeed manifold that is used. Plenum shapes and sizes vary and the angle they extend from the head. So you might have to do some custom work to keep them, but it's possible and it's been done before.
@@ksisjdm i plan on using excessive centerfeed for my k24a jdm
Hi K, hope youre good bro.
Well, I ordered the K-tuned centre feed intake manifold a month or so back and have just been informed that they have discontinued it, 😟😞. A vendor from your side of the pond has asked me if I'm interested in any other manifold and has suggested a Gato centre feed. They look similar to the one I wanted but I know next to nothing about the company. Can I ask your opinion on Gato and if you know much about them and the manifold I've been offered for my k24a2?
Respect bro
GATO is a reputable company. Downside is their centerfeed manifold uses a very large runner which focuses more on high rpm power and mostly used for boosted applications. They are good manifolds though.
@@ksisjdm nice one K, thank you for responding. I might have to pass on that then,wanted thinner longer runners ideally. There is currently no ETA for the revised K-tuned K20 version of which I'd have to use an adapter for K24. . Sigh
In the meantime I'll be getting DC 004 Cams, after speaking to Jeremy it seems the 004.5 cams would lose me some mid range but give about 7bhp more.
Could I continue with my build and run the 4's with the rbb manifold until I finally get the K-tuned or should I just wait do ya think?
You could continue theres no rule making you stop. Just expect power to be restricted a lot by the intake manifold. I would at least use a RBC intake manifold in the meantime or something
@@ksisjdm looks like the centre feed manifold will be available early March 2019, , , 🎊🎉! Shall also be getting the powersteering relocation kit and the adapter for the k24 😎
@@ksisjdm I got it!! Now I just got to figure out keeping my PS! Would using the PS relocation or their EP3 pulley kit not be any help do ya think?
What motor do u have in ur car?
A 88mm K24a2 block with a K20a2 head
I would argue that a manifold that is too big for your engine makes the engine run even worse than with a manifold that is just right. Thats because the air velocity will be lower with bigger diameters.
Please correct me if Im wrong!
You're correct
But this bit of info you placed here isnt relevant for what I have or what I explained in this video.
what engine block are you using? k20a?
+Double Clutch No. A K24a2 block bored to 88mm at 12.5:1 compression.
This is what I was running but with a built K20A2 head. I was running a stock Type S oil pump and starved cylinder 4 of oil and spun a rod bearing... So a $13k motor lasted me less than a year...
sbounty3 im planning to turbo a k20a3 with stock internals do you think it would last? i found one cheap in a scrap yard with less than 50k mileage. did you turbo yours aswell?
I didn't I was NA running Pauter Forged rods, Supertech 88mm 12.5:1 pistons, all ACL bearings, full Supertech Beehive valvetrain, IPS K2 cam's, head and IM ported by ASP Headers. I was making power up to 9k RPM's, but didn't realize the type a oil pump wasn't supplying enough oil to the cylinders at high RPM's. I think with the K20A3 if you use a type s oil pump and have it ported, or pick up a KMOD, ERL, etc... you should be ok. Also, make sure you invest in a better head gasket (cometic), ARP headstuds, and colder spark plugs and you should be ok running 7-9 lbs of boost for a while. The problem with that motor is the internals are pretty weak.
I am however planning to boost my new-er K24A!
Yea bro gives me a way better idea. Dope vid and yea I'm going k tuned errrthang👍👍
if the intake manifold runners on the skunk2 are bigger (at the flange exit) then that of the cylinder heads intake ports entrance. this create intake air reversion and you will actually make less power then a stock port intake manifold, the transition of air has to be smooth if the air hits a step it messes up the flow pattern into the cylinder head. in your video it looks like your cnc s2 intake had bigger ports then your hand ported cylinder head thats why i am commenting.
I'm well aware of how the air flow works. The CNC skunk2 intake manifold is perfectly matched for the CNC 4piston pro 156 head it was ported for. The matching head with that manifold was directly back to back tested against the unmatched ktuned manifold and still the skunk2 manifold was outperformed until reaching 10,000 rpm where the skunk2 finally had a small edge. This video was just to give people some generic info and a visual of the two company designs that are readily available.
All the testing that was done was legitimate and in fact favored the skunk2 but the results spoke for themselves.
Childstar do you think this K-tuned intake is necessary for achieving 300bhp on this engine? I've just imported one to the UK and it'll be going into a 5th get prelude. Only thing I've kinda decided on so far is upgrading the pistons to 12:5:1 wisecos, and getting stg 2/3 cams.bottom end shouldn't need sleeving should it?I want it as my dd
On my engine and with the fuel I'm using, yes, I need a large intake manifold to get to the 300 hp range. If I used better fuel I could use a smaller manifold
How much did your engine build cost roughly?
Not really sure, maybe 4k overall. I don't know. Some parts were sold to buy upgrades to offset retail prices.
@@ksisjdm I just picked up a 2000 ex, following your build, I want to go fully built N/A, I was debating keeping the D16Y8 it came with but after doing some research it seems the K swap is the right choice, what I still haven't decided on is if I should go K20 or K24. After having yours for several years, what would you do if you had a fresh build? 🤔
In all situations I would do a K24 build every time.
K24 it is.
👍
Wish i would've watched this video months ago lol i would had purchased the Ktuned system instead of the S2 🤷🏻♂️😅
Child star what can i do to beef up my h22a engine
+Cary Williams start with bolt ons all around, and then id look into the h2b conversion. One downfall of the H is that slower transmission. A b trans will really make that thing take off
Childstar what bout magnus intake manifold?
What about them? They make more than one manifold, and you should know Magnus makes the ktuned manifold to ktuned specs. Same information applies to ALL companies. Every manifold is designed for a specific purpose, there isnt some generic layout.
That velocity stack is no good, shoud have full radius down to the plenum floor. That sharp lip creates turbulence that cuts the flow to the stacks.
Uhmmm why are you telling me? Lol not like I designed skunk2's intake manifold Haha. Thanks for watching and commenting.
It was just an observation, and I find it very odd that a name brand go fast part is designed like that. Would be interesting to cut a radius to that corner and running it before and after on the dyno.
I feel you man, just messing with ya. But you're right for sure.
I thought so, thats a beautiful engine you have built. Need to watch more of your vids for more details. This one just popped up on my feed.
Center feeds only good because it gives equal air to each cylinder
+Nick Stevenson not true. That's a fact if and only if the centerfeed design is well made. The skunk2 centerfeed without a plenum spacer has shown to starve cylinder 1 and 4. But your comment is basically legit.
Thanks for watching dude.
i subbed to your chan last week, saw a new video, clicked on it. now it says I was not subbed. I did not in sub, wth is going on?
+Skinnyfish not really sure what happens with that. It's something with UA-cam itself rather than my channel or something I've done. So I'm unsure what happened
thanks for the reply. must be a youtube issue or something. anyway love your videos. good quality and good info. great build. sh*t is tidy! gives me some inspiration to dust off my old 91 prelude, thanks!
The center feed is still climbing at red line vs the other one that is falling off and 10hp is nothing the center feed is better in my opinion from what I see ever on the second motor you test you can see how much further it carries the power vs falling off and again 6hp difference is nothing the center feed shows the best power band 👍🏾
Skunk2 manifold is better in the end cause you can open it up and polish it and add spacers you can't do that with k tuned. Also is you bangin bloods in the video. I knew childstar was a gangsta
It's not really better per say, it depends on the application. Its not always better to open things up and make it huge internally. That effects the powerband greatly. So it depends solely on the overall setup
300 hp, if doable... I'm taking the old engine out, and getting body work done... a 08' tsx, with ECU, will run me $700..
+Dolla Washa can't use the tsx ecu in your case. You need something like a prb ecu. And if you want 300, you need a complete build. Either built block and a built head, or a stock block with a really well built head, induction, and exhaust setup and good fuel to still reach 300 all motor. Might as well start with the cheapest block you can find and build it up for a reliable less stressed 300hp engine.
Lavar ball looking asssss 😂😂 all jokes bro
I dont recommend sanding down the insides, I see people make them rough on purpose to make more power, sort of like dimple porting.
Understood, but this one was CNC ported by 4piston and has shown improvement over the original rough casting. But I do know what you're referring to and you have a good point for others.
yo why is UA-cam unsubscribing me from people youtubers you're the 4th person
+kryptonite360 damn I have no idea. I've heard of this happening but I'm not sure what the cause is
K tuned is the Creme da la Creme for k series performance parts! All I run!! Skunk 2 is total cheap garbage I learned that on a previous project Honda build!
Someone get this man a ITB SETUP......
+bross 956 how would I enjoy my car daily the way I do when I put it together if I was on ITB's?
