100 hp per liter na is cool, a ls3 6.2 only makes 70 hp per liter at the flywheel. looking through a narrow lens here, but these numbers are closer to a lsa supercharged 6.2 making 580 hp with 6.2 liters + a 1.9 liter blower to add. crazy to think a 7th gen k series did that N/A XD (note i know this is modded honda vs factory warrantied stock engines from gm)
@@Almostboosted oh for sure it’s plenty of power don’t get me wrong but I’m replying to the other comment that this isn’t crazy power to where you need to upgrade a Oem fuel rail
Had a 06 civic that I blew the motor in and slapped a k24 out of a tsx in and tunned with kpro by someone I found online , and he got it right ! Running 5.0s down
06+ tsx (k24a2) does have the better cams (bigger secondary lobes) but all k24 came with 25deg vtc. They never came with an rbc vtc cam gear, you have to install those yourself out of any k20 engine (including base model) 👍🏼 you can also pin the k24 vtc to have it fixed at 45deg, any more and you run the risk of valve to piston contact
@@Almostboosted thats Great! I planned on doing all that as well. I wanna shoot for a 450-550 HP car. So even after the aftermarket mods to the K swap even further aftermarket will need to be done im guessing... cam shafts, pistons, fuel injectors... etc. But, Is it necessary to tweak an aftermark cam shaft to 50 degrees? Or do you only do that with the stock ones from the K series motor
I have a k24 in a 04 accord has skunk 2 header, manifold, and fuel rail. Battery was relocated so it can now fit a k&N intake with the box trying to find the headlights with the hole though them its not fast and i cant really push it with a AT but it is enjoyable
Easy 15-20+ hp left on the table just adding a simple 50° VTC cam gear, and a used set of drop in cams.. From everything I've read... I haven't dynoed my build yet, but I sent with a Z3 head and almost identical setup.. I'm excited to see some numbers
@@Almostboosted hey can you guide me on how to make sum power k24z3 in a 6speed tsx 201 hp stock but it probably no where near that because i used regular know since i lost so many races got humbled let me know sum little thing i dont think the k24z3 out of a 2009 tsx is very good because id the oil consumption through the piston ring and valve stem seal i looked up the issues but will it hold some power with out blowing out
Due a compression test to see how healthy the engine is. The k24z3 is pretty much the same as a k24z7 out of a 9th gen civic si. Not considered to be a true vtec and with the r40 head style. I seen people put bolts ons and get decent number out of them.
@@Almostboosted i dont need conpression test is a well abused engine by me i redline till the gear hits the limiter and wants to pop out because it only does 7200 rpm max has 175k already its ok oil consumption was a recall i think rings get stuck and oil sweeps trough into the combustion im the car 7th owner so im not the only abuser it runs like a fucking champ thou and will beat anything with less than 170 torque pretty sweet first manual car is it burns more than a quart every 750 miles i might do a forged wiseco piston set again a drive it like i stole it engine seems healthy idles good not check engine might see why does it stink so much when i step on it to the floor its probably oil and gasoline out the exhaust pipes but i love the car will add every quart it needs and will never be close to the first dot on the didstick
@A A you would need hondata flash to tune it. RBC style intake manifold. 70mm or bigger throttle body not sure if that's a drive by wire. Bigger Injectors 410cc or higher. Cold air intake 3in. Bigger exhaust manifold/header. Rsx type s oil pump.
I just learned more in 10 minutes than I did in 1 year. I have a 2004 Accord EX with the K24A4 5 speed manual with 150K of well maintained miles. Right before the pandemic had the whole car serviced. Timing chain, water pump, clutch, brakes, etc . (so just the i-vtec) . I used to have a 1995 Integra GSR. Originally, I was thinking that I could change out the top half of the engine and make it a true V-TEC but it sounds like I would need to change the pistons and rings, ecu, and the oil pump to unbalanced? Should I just chuck the A4 and get the A2 or can I build on what I have? Or do I turbo the A4? I want to have something similar to my GSR NA far as performance. Thank you in advance!
Yes that's correct to swap over a rbb head or a k20 head you would need to change the pistons out. You can still keep the balance shaft oil pump. And would definitely need to flash the ecu. I would recommend just swapping in a rbb k24 buy you would still need to flash the ecu.
I'm running Kfrank K24a/Z1 with basic bolt ons and a dyno tune. It's not the fastest but sure is a hell of a lot of fun as a daily. Got a rear sway bar and poly bushings, motor mount inserts and stock shocks. I'd really like to add an lsd, buuuuuut it's more money more money... Honda is the BEST!
Sick build bro, I just got my k24a in my ep3. I did the 50 degree cam gear, I don’t have that oil pump yet but it’s definitely next. I have full bolt ons (stock injectors) and I have a 70mm throttle on stand by my tuner and I think we should make and are shooting for 230-240whp with what we got going on. Clean set up as well, I definitely need to get a lsd I have the ep3 4.7 transmission, I’m going to be lighting up one wheel lol I would definitely suggest the 50 degree gear if you haven’t already 🙌🏻
Thats awsome! Yes i have one but just holding on installing it. My buddy and i have the same mods. Only thing he has a 50vtc and he gain like 7 more on torque i made 195lbft and he made 202Ibft. Not sure if you know but the 50vtc on k24 only goes as far as 40 degrees to prevent interference.
Limited slip makes a world of a difference especially with these K engines.. I was running a similar setup when I through in a near stock K24A2 in my ep3.. After I added an 8th gen Si LSD, I was mind blown with the over all differences
I would have to say it would get to a point and max out, to be honest. And I would have to see his setup and what fuel he is using. I have seen people free up so much load on the serpentine and have a killer tune that would be a nightmare to drive as a daily because you would not average no mpgs. It's pretty much just for the track.
@@Almostboosted I was curious because I have a k24a in my fa5 civic si I wanna get as close to 300 without a turbo but I still somewhat new to the k series motor on what directioni should go because it is a daily driver but i what power. I've been thinking about just stright up slapping a turbo kit and push close to 400 hp

Cool video, thanks for sharing. Doing my first swap now. It reminds me alot of the heros journey. So many people have done, but it still feels like an initiation. Clean setup. The only thing the vid could have possibly used is a start up. Left me wanting to hear it.

They upgraded the intake cam on the 06-08 TSX. The 04-05 and the JDM K24a are the same through and through. The intake cam is just a tiny tiny bit larger on the 06-08. No biggie guys.
How's the build holding up in 2022? I jus picked up a type s oil pump, 50 degree VTC cam gear, and a k tuned oil pan assembly for my k24a motor. My goal is to drop it into my 99ek by summertime. Fingers crossed i can make it happen 🙏 😌
Got a k24a from jdmdepot and I paid 1k sent to my door step. It that was covid days when the world was ending and I got a euro R k24a hahaha I guess I got a deal that day lol 😂
Hey nice build bro 🔥I have almost the same setup I was going to ask if the rbc would cause any damage running it on a stock k24 with the regular vtec degree ? Basically I’m asking if your set up will be good if you were to leave it like that
When you mod the car for power, your ecu doesn't ready it properly because it already has set parameters put in place. It messes with the tune a bit. But simple ones are like cold air intake. Anything that would alter power would require the ecu to get flash.
How can i run a cut RBC on my k24a? Specifically asking because i see there is a coolant port on the right of the intake manifold and mine was cut off.
@@Almostboosted ok thanks i’ve looked everywhere and i can’t find anything about the rbb4 only the rbb3. i am aiming for 240hp too. i will try all the same bolt ons as you and hopefully make it to 240hp.
@@Almostboosted I plan on cnc porting my head, balence internals, and getting matched injectors and getting a motec computer so I can daily it worry free, gonna be a zippy lil crx😊

i have an 08 accord and i’m trying to built it but i’m having troubles with finding parts that will fit, if they is any chance we could dm and talk more please i would really appreciate the help!!
A stock k24a4 would not be able to this. The cylinder is not true vtec and. If you swap the cylinder head a true vtec you would have to change out the pistons and roads because of the clearance.
I'm sure it means the year it was manufacture. I'm thinking the same, only way of finding out is measuring the exhaust cam lobs to see. But I have done research an according to it dosent matter the stamp any jdm k24a is equivalent to 04 to 05 tsx k24.
Definitely! You are going to have to research to see what subframe you need. Also the motor mounts needed. The cost not sure after and during covid19 everything has went up.
You can use your stock ECU but it will run really lean once in VTEC, and that's not good. But I ran my car with a stock rsx-s ECU with my k24 swap for three years lololol. People will tell you it can't be done but that's just not true. I now have Ktuner and am properly tuned so I mash on my car all I want now.
Does the DC5 Integra Transmission bolt up just fine? I know the engine pattern is the same, but is the Chassis mount any issue? Been really thinking of swapping as my CL9 Accord Euro "essentially a TSX" has really long gearing that i'm not the biggest fan of.
No you only cut if. You have a k20a2 z1 k20a3 or k24a1 cylinder head. The rbc came in the k20z3 and jdm k20a from the cl7 type r. The k24a/a2 share the same cylinder head as the k20z3 and k20a type r found in the fd2,ep3 type r and dc5.
@@Almostboosted Well almost. The K20a2, K20z1, k20r all have the same cylinder head. The K20z3 is almost identical to the ones I just listed with the exception of material built into one of the intake ports, then the K24 heads have smaller intake and exhaust ports and don't flow quite as well in the upper rpm band, but are designed to make more torque than their little k20 brothers
I'm running the same cold air intake. Do you think it's restrictive? I see people's 3.5-4" and they look like they'd breath so much better, and with less bends.
Hi bro. I got 2004 model k24a3 accord 6 speed manual 190 hp all stock engine. Do I recommend to me 50 degree vtc + good intake manifold + aem fuel pump + rdx 410 cc injector+ ECU İf u say yes all of this part how much power can I get min ? I already 190 hp now.
Yes. Now, I'm not sure how much mileage your engine currently has, but that plays a huge part. I would say about 220 to 240. Because that k24a3 is pretty much the same as a k24a2
I am getting ready to do my K swap. I have a 91 integra, but first i wanna get my wheels and suspension before I go to the motor. I am going to do the k24A2 with the k20A2 head, Type R tranny, and the K pro ECU. Im going to first start looking for the motors in junk yards before spending up on that and other parts i can obtain there. I have no experience with motors and cars but I am really infatuated and will be all in when i get going. Do you have any early advice before i get started??
Nice k20/k24 is a sweet set up. Make sure you make a parts list with everything you need and start looking a head for a tunner, also source out a good and exhaust pipe.
@@Almostboosted I’m not entirely sure what all parts I would need just yet. I know a good handful, but I think I still need a bit more. I will do some when it comes closer to that time
@@graysongrzybowski943 one thing I learned was that so many people told me things like “all you need is this, this and this” “it’s not that much it’s easy.” But in reality it’s not getting the engine and trans that’s hard, it’s all the little shit that people forget about that adds up and is time consuming. My advice would to do as much research as possible and make a list like the previous commenter said and don’t let people fool you - it can get pricey real quick! Also one more thing, buy the items you’ll need that are no longer manufactured first because they get more expensive as time goes on. Anything that can be bought quality aftermarket can wait. Buy the discontinued Honda oem stuff first and good luck!
@@jesselee4405 No I have not. I am a ways out with this because I have turned into an Investor and that is where my money is going. I am still waiting to buy my suspension. which I almost have enough money for that.
Pull the valve cover off check to see if you have 3 lobes in the exhaust side as well. If you do you have true vtev, if only 3 lobs at the intake camshaft then not.
Not sure if kpro would be a vital option for automatic transmission. You might want to see what other standalone out there that would allow you to change transmission gear ratios. But start out with bigger injectors, 410cc or higher. Rbc intake manifold or skunk ultra. Bigger throttle body 70mm to 72mm. Type s oil pump. 50 degrees vtc from a rbc. Cold air intake that's a good start.
How do I know if i have an rvb head. I have a 04 tsx with intake and exhaust I feel like it has vtch and gets up pretty dam good but I want to verify is I do have true vtch
The head will be stamp with RBB 3, not sure about RBB 2 or 4. Also pop the valve cover off and check tonse if the exhaust camshaft has vtec by checking the lobes if it looks adentical to the intake side than your good.
@@Almostboosted bet thanks bro I feel it kick in at 6 k rpm but just wanna go ahead and check it out 😎 I’m probably going to copy cat u on ur build bro how do u like it is it still the same ?
@@riccoronado430 yeah is same for me at 6k vtec kicks. For sure yeah is a very simple build for what I did I'm chilling with it making 240hp I'm trying not to get greedy lol
06-08 k24a2 US models is where it’s at not jdm unless ur gonna bulid the head or do a PRB head swap or a RBC head..on all jdm k24a’s from tsx or accord has smaller vale springs like the common base k motors has..google it’s the info is all out there even on the Us model tsx 06-08 k24a2
Yeah that’s definitely the better option. Only thing is more than likely the USDM k24a2’s will have high mileage where you can get a jdm that has way less. And honestly if you end up boosting I don’t think those extra upgrades from 06-08 make a huge difference imo.
@@droboyjr Naw, the 06-08 has a better intake cam than the jdm k24a and 04-05 tsx engines. It's such a minor thing it's not even worth worrying about it. They did changed the rods too though between but there's debate whether the jdm and 05-06 rods are better or if the 06-08tsx rods are better.
I'm running a k24a2 with rbc intake, 50 degree vtc, skunk 2 exhaust, 3 inch intake, and a budget k swap header. Also oil pump upgrade, modified injectors and a 255 fuel pump. I made 220hp 183tq, with my mods I figure I would be around 230ish hp. Trying to get to that 240 hp lol.
I wanna change my rev fro 7.300 to 7.800 but idk what to put for the high restart the low limit and low restart somebody help me. Plz I have cai rear header no cats and e3 spark plugs
This question is better suited for a tunner yoshtuned. Com he will be able to help you he also has Instagram if you want to to dm him just let him know I recommend you.
I just got a 2010 acura tsx already did window tint, sound system,cold air intake,and i just ordered coilovers.what can i do to make it a lil faster? I have a 09 civic si sedan its moded bud not tuned since there isnt a local tuner around.
@@Almostboosted thanks i just wanna boost up my acura i just had it for 2 months so far its a good fun car even tho my civic si its way faster but smaller lol
Definitely they have RBC style ones just make sure in the details is compatible with the R40 from the k24z3 with the single exhaust port. I have a k24z7 in my 2013 civic Si and is the same as your k23z3 and i seen RBC for them same R40 head.
It could be true man! The most I’ve seen is 240 with that same set up. I am currently at 233hp & 197 ft-lb of torque running an rbc with the stock k20a2 tb, 50vtc and type s pump on e85.
@@Almostboosted So thats my next question, is your coupler a 3.25 to 3inch piping? ZDX needs 3.25 coupler but order 3 inch intake piping and its to small because they measure from outside of pipe. so would I need to order 3.25 inch i take piping instead to match the throttle body inlet?
@@michaelmata10 not sure on the diameter but the one the comes off the throttle body has a bigger inlet side. They could be 3 in since it was a tight fit.
Not all k24a are considered the same. You have to find the one with the RBB head with 3 lobe on the exhaust as well. Those are k24a2 tsx equivalent also year of the engine plays a good part.
@@Almostboosted I’ve got a stock 2011 crv exl awd that’s paid off and I wanna dick around because I haven’t seen anyone with a modded 3rd gen crv there is an Acura equivalent in town but it’s a 2015 or newer.
you mentioned 2.5 diameter headers verse 3.... why are you stating that it is bad? Velocity and pressure increase a fluid with a smaller diameter pipe. I thought about going with a 2.5 diameter pipe until it got back to the cat, then change to a 3. but i dont really know much about putting this stuff in yet. I know you want the flow velocity to get out of the engine asap which would happen faster with a smaller diameter pipe.
You'll need a Ep3 idler pulleys or the AC and PS type of pulley. You'll also need a usdm base rsx or crv waterpump housing with matching tensioner. If you wish to ruin oil cooler You'll need either k20z3 waterpump housing or rsx type s type.
So here’s my issue I’m having on all platforms. Threads, fb groups etc. I have a jdm k24a engine rbb3 and I also have a RBC manifold. I noticed on the head of engine it has two coolant ports and the RBC manifold only has one. The kidney looking one. I noticed your rbc is not cut! Which I also don’t wanna do cause I paid a lot for mine. Can I just run it without cut. And what gasket did you use? I have the k20z3 thermo gasket from skunk2! Please help Honda family! I’m almost done with build and I want it to be done properly! Thanks in advance for your help!
Why o why dont they put a throttle body under the intake manifold? You know, so it can have an air intake sucking air right under the radiator. Right on the open space under the radiator. These people only care about money.
