How to Build a 300HP K24Z Engine

[@flyboy8282]

THAAAAAAAANNNNNNK YOU!! I swear nobody cares about the 8th gen 2.4 Honda Accord I've been looking for a video like this for years! I bought my 2.4 '08 Honda Accord coupe in 2012 only to figure out there is nothing for it. All the aftermarket company are too cheap to try something like this and they only care about the Civic Civic Civic Civic ugh or the v6 Honda Accord coupe. They completely skipped over the 8th gen Honda Accord 2.4. Thank you man I cannot thank you enough for doing this!

[@blazingsilver1825]

FOR REAL, show some love for the accords

[@emilyhamby5154]

2.4 has no following

[@Greengoblin0481]

Tsx gang

[@wesleymckee9462]

Hey did you ever find anything on 8th gen accords?

[@tyscl9516]

Just to share more technical knowledge about Honda's i-VTEC because I've got nothing better to do. Honda made many versions of their "i-VTEC" systems. The performance oriented i-VTEC incorporated valve lift and timing on both the intake and exhaust side. Engines like the K20A, K20A2, K20Z1, K20Z3, K24A2, and K24A3 have the performance version of i-VTEC. Some engines like the K20A3 and K24A8 only had "i-VTEC-E." Those engines don't incorporate variable valve lift, only a 12 to 16 valve switch over and variable valve timing. These engines usually produce more low-end torque and have better fuel efficiency. However, they don't rev as high and make less top-end power. In addition, their switch over is extremely early in the rev range and barely noticeable. There is another version of i-VTEC that incorporates variable valve lift, but only on the intake cam. Engines like the K24Z3 (like the one in this video) have this version of i-VTEC where VVL only occurs on the intake side. Both intake and exhaust sides still have VTC, so this systems sets itself in the middle of performance and fuel economy. You can generally tell the different K-Series engines apart by the intake manifold cover. If the lettering is red, then the engine has real "i-VTEC." If the manifold cover has black lettering or no lettering at all, it's most likely the "economy i-VTEC." Of course there's the head stamping to go off by too. I'd love to hear more facts from fellow Honda fans and enthusiasts. Thanks!

[@OneNoteScream]

Every forum I've ever seen always says the z3 isn't worth it but I'm glad to see someone putting work into the 8th gen.

[@justainereid5]

you are the best at explaining things like B is for Build and i love this project. Just keep going because this project is personal to me. Really need all the help and knowledge i can get

[@milanmastracci]

Thanks Justaine! I'm excited to get this going since I drive my Honda the most out of all of my cars. I am hoping to enjoy the extra power day in and day out 👍

[@Gage7SLR]

For those of us who don't scroll through all the comments, does anyone know what happened to the project? I was hoping to see the completed build and dyno.

[@iron-gamerstv]

I'm not sure, I think he built it and then he upgraded to newer Civic SI? But, im not sure.

[@THECobrabitch]

Yeah he scrapped the idea cause "ThE civiC iS 150 PounDS liGHteR" or some stupid shit like that.

[@mathewcarbajal3934]

He sold the accord and got a civic

[@bennylol4374]

U are one of the only accord coupe people on the platform thank you for showing all of us how to wake up the z3

[@estefanaraiza5958]

hey Milam, I have a 2009 accord coupe k24z3 and I'm planning on doing the exact same thing. I'm gonna model my build after yours ! good luck

[@milanmastracci]

That's awesome Estefan! I hope this works out for both of us 🔥

Finally! I have a 9th gen civic si and I was looking into doing this and I can't find it anywhere, so thank you! Also I made 232hp 183tq on my 9th gen, k24z7 however I wanted to get on my exhaust and intake so I finally find you with all this!

[@milanmastracci]

Well I hope this works out for you! 👊 What mods do you have that have given you that power?

[@daviddaoust8841]

This is so awesome. Thank you for describing the function of the lobes

[@JohnDoe-mx1sq]

I've seen these things in pictures but seeing the R40 head in this video makes me want one so bad. The integrated manifold is beautiful.

[@lowtopics5253]

I have one but want a k24a2 head lol

[@yosh_tuned]

I'm tuning a guy in Central America that has the K20z3 head on a K24z7 block. Making great power even with the stock Z7 oil pump and 1000ft above sea level. Made 233whp and 190tq on a base run. We're aiming for mid 240s by the end of it

[@seanquattro]

K24a2 for the win. Love the a2s!

That's what I'm trying to do!! I want more power. I can't wait to see this done 😎

[@RWTFska8te]

You're literally doing everything I couldn't do on my old 8th gen haha. Really hyped for this build man!

Who's to say you can't? Or do you have an S2k? The one in your profile pic?

[@RWTFska8te]

[@kwckhm7757]

I have... I have... I have... lol.... you have a stripped down engine with all different stuff. So basically you have a 2.4l on steroids. Great video

[@salmanomar97]

This is going to be awesome. Slap a turbo and it will 400+ hp

[@diycarhome9151]

Just adding if you get 300 hp out of a 4 banger your doing good. Because on Nicks Garage (You Tube) from Montreal, Quebec he does a lot of V8 builds with forged connecting rods and pistons. Average Horsepower on his Dyno is 600 horsepower out of a V8. So your half of a V8 an 4 cylinder so if you where to get 300 hp (non turbo-ed or super charged) an Good accomplishment. Will be an interesting build for sure.

Can you please explain the transmission What was needed? I have a k24i auto..can I add SI transmission?

[@kudzy11]

[@Brrreezzyy]

Can the 2004 Acura TSX transmission work in the 2011 Honda Accord

[@anthonyhernandez1953]

Mannnn I drive a 2014 civic si , I want to do the exact same thing , the info on how to put a rbb vtec head is very limited, I’m glad I found your videos on KZbin ! How’s the build going ? Can’t wait to see the end result!!

[@soggycivic8594]

I know this is an old video, but 4 piston mentions that after porting the r40 head, it is the best flowing head out of all k series for all motor applications. You can actually add vtec cams on the exhaust side of the r40 head, and it’ll be better than the k20 heads and rbb (k24a2) head

[@milanmastracci]

If that is the case, that is new information as 4P has recently begun putting some work into the R40 head.

[@able_trucking780]

k24a2 with type s oil pump, vtc gear skunk ultra manifold with bigger throttle body and race header valve springs, 3inch exhaust and a 4inch intake on e85 will do 300whp reving it to 9k tuned.

[@milanmastracci]

Do you own this car? Or you've seen it?

[@Brrreezzyy]

Can the manual 2004 Acura TSX transmission work in the 2011 manual Honda Accord

[@marvinreyes6270]

How about jtw5 tranny 6 speed from frv 2009 what can you say about the final drive

[@zunojose]

Make sure u use NGK plugs for this set up I read the part list you posted and I saw you are planning or planed on using BOSH spark plugs Honda motors usually perform best with NGK or Denso’s

[@romper4444]

ZunoFG4 it sounds silly but its true. I cant tell u how many times ive given several different types of bosch plugs a try and the engine always feels just a bit off. Back to ngk's or densos and u can tell the slight difference in the smoothness with which the motor revs and idles.

[@MrMikeT89]

My experience is the same, NGK is usually the go-to

[@Healthliving1967]

Well that shows the differences between the American Acura k-24 engines and our Australian accord euro K-24 engines-my 2011 accord euro cu2 luxury has the K-24z3 engine but it has vtec on the intake and exhaust cams unlike the K-24 in this engine. There are so many variants of this engine and are different in other countries. My wife has a 2006 odyssey with a K-24 A3 but in America you guys got the 3.5 v6 engine in them.

[@hackzor4]

I hope these new parts are better quality then the timing chain kit.

[@milanmastracci]

LOL 10000% BETTER PARTS!

come down here and do mine next u bloody fool.awesome

[@Kelvinle469]

So much knowledge 👍👍

[@p.diocee8177]

Cool build! The 06+ tsx head I've heard is much better than the 04-05

[@milanmastracci]

The 06-08 head is better in the fact that the camshafts are slightly larger, and the intake valves are 1mm larger. The cams I'm swapping out, and I may upgrade intake valves. We'll see

[@hyderjaved5895]

Whats the update on this man ? Im exited for you

[@letmefindout81]

If it's a daily is best to use cast pistons, forged are best for track use only vehicle

[@keithcannon3682]

You will need to properly port and polish that head in order to make 300 hp all motor. Be a lot cheaper to leave the k24z3 bone stock and put a gt30r turbo on it. That will make 450 whp a lot easier and cheaper. Hey....good luck with the build!

[@phuhoang4678]

Will you make a video on price breakdown of cost to do a kswap?

[@J_K_L-ef6nr]

That is an interesting build, complex when it is already known internally more focus on the block that Honda k series are pretty reliable as proven by both the internet and various youtube channels that mainly boost these motors and everything is stock is kicking over 350 HP day in and day out. I would have thought this was a simple budget build, so a mild rebuilt head with cams and a RSX VTC timing gear, PLM Header, etc, a tune and go can reach 300 hp goal and still be reliable...Even i see that you have the ATI damper total over kill, would it have been just been easy to just use a OEM Honda ITR (the similar RSX type S) crank pulley and your good None the less good luck on the build : )

[@milanmastracci]

I'll be getting into the oil pump in a later video, as the Type S oil pump cannot be bolted up to the K24Z blocks. It's nice for the K24A blocks as the threaded holes of the block align with the holes in the pump. You'll see how I get around that problem.

[@DidierBan]

From bottom of oil pan to top of valve cover , how tall is that engine?

[@frankhernandez6524]

I want this combo in my mr2.

[@dominio123]

Ima try to do this

[@DoubleDrastik]

How much did you spend on upgraded components ?

[@natekramer6135]

Are you gonna be doing this to the civic eventually?, i am thinking about doing this to my 9th gen civic and having a video reference of the build would be awesome.

[@Rickey_B0bby]

Did you buy all the parts at once or did you acquire them over time and did you ever finish the build

[@gustavocastillo9954]

Hyped!

[@milanmastracci]

🔥🔥🔥🔥🔥

[@audiemuniz6445]

Very nice! Are you racing those? If not, is lot work and time consumed all that power just for street.

[@chinchy111]

Wow i always thought the first and second gen tsx was the same exact engine

[@nigelmcphearson]

It's just about impossible to find a complete, derailed build of a k24. Three are plenty of videos where they tslk sb2👍🏼

[@AnthonyMo]

Glad you're making these videos! I just got curious on what it would take (price and difficulty) to build a Honda engine like this since I always hear people talk about it

[@milanmastracci]

Well the price is the biggest part of what you can and can't do. If money is no object, I'd be buying a billet K24 engine block, but they're upwards of $8k right there, and that isn't even touching internals. I have a sheet in the description box of this video that I will be updating as I buy parts and spend money towards this build.

[@gringotroller]

Whats the difference between k24z1 and k24z4?

[@cameronw.4369]

Dang I kinda wanna do this to my 09 accord 4 door lol

[@tonydean1122]

So did you put the a2 head on the z3 block? What did you have to change to do that. I never saw a reassembly video

[@omega_chuckygaming2061]

You can also make more power by upgrading the cooling system

[@Simon78]

This is gonna be interesting! Good job mate! Hey what engine management are you considering; aftermarket needed to get to 300‽

[@milanmastracci]

I currently have Ktuner, but I need to find someone who can tune it to its full potential

[@User0player1]

Looking to replace both cams on a K24Z3. The OEM cams (14110-RL5-000 and 14120-RL5-000) are $600 plus each. Are there any other less costly cams that will work in the K24Z3?

[@sterlingmaxima101]

What happened to the rest of the videos for this series?

[@kswervo808]

If you have the k24 engine with same block why swap the whole engine an not just the head or build the motor you have ????????

[@Brrreezzyy]

Can the 2004 Acura TSX transmission work in the 2011 Honda Accord

[@spacechimps]

Z3 head is good for turbo, shorter collector/tubing which relates to less lag, check bisimoto the civic he just made he explains it all.

[@milanmastracci]

I would have to agree with him. The K23A1 that came out of the Acura RDX is an OEM engine that came boosted and it has the same single collector found on the cylinder head. It is a smart design and makes pretty good power for an engine with 8.8:1 CR pistons.

[@spacechimps]

milanmastracci also love the videos man, as a Mclaren tech it’s awesome to see someone working on things and doing the most quality job they can, used to watch more when I had my tsx but keep it up.

[@thatguywholaged]

Hi milan I have watched this video atleast 5 times now.. I have a 9th gen si that is why I very interested, how is the build coming along? Love you content man!

[@Nzx.NghtRNNR]

Is building a k24z3 block worth building? Or should I get an k24A2 block? Also will it fit with a k20z1 head? Will it fit in a RSX?

[@jonathangoyette594]

If i put a k20z3 head on k24z3 block will I be able to have as much power as this set-up?

[@loganstrid8724]

Hey I was planning on building a k24z3 turbo for a DD, what do you suggest? Should I gut it and rebuild it or run it on stock internals? If I gut it what pistons and rods should I use? What type of valve/valve springs and retainers should I get? This is my first time building a motor so any suggestions or support is really appreciated. Thank you!

[@stanwardoshiro]

What was Honda thinking when they designed the Z3 head?

[@xkonquerred6990]

This means I could do it to my 9th gen si since ILX & 9th gens 2012-2015 have the same engine k24z7 motor/r40

[@justnwin1026]

If you have a 04 TSX what head and block would you use, or would you just keep the same engine and just change the internals?

[@wing0291]

A supercharger and a tune in my 2005 tsx it should be enough for 300hp ?

[@k24oreo84]

I have a 2013 Honda Civic Si Sedan K24Z7, I have low compression on cylinder 1 and 2 so I need a motor a used low miles motor runs me 1800. What do you recommend to do

[@t.j2881]

Tuning on 93/94 octane I assume since you're in Ontario? E85 is hard to come by up here.. You're going to need some serious head work to make 300 whp on pump gas, p&p, 12.5:1, 80mm+ TB, big tube header, ect. Not that it hasn't been done, because it definitely has.. But the stock ports on the head will be the one thing holding you back. Contact RaceHeads in St. Andrews Ontario. The world record stock block H2b is running a Raceheads cylinder head, 300whp on M5 fuel.

[@humzamalik1704]

Bro, my current 2009 coupe makes 300hp with basic bolts ons, I’m interested in seeing how different it’ll be with the 4 banger vs the v6 which I have

[@milanmastracci]

From my understanding, the V6 will have more low end torque even after I complete my build, but mine will be lighter and should have a better top end. I'm speculating right now but we'll see 😁

[@Youngflynsaved7]

What civic si lsd transmission are you running with the k24z3 ?????

[@tonylugo9]

So can I just swap the head right over no issue I know you upgraded the internals but I’m genuinely just asking if I can swap the k24z3 with the k24a2

[@jack94503]

Hi Bro...what about the wiring of the engine and ecu?

[@03kwam65]

I have the k24z3 block on my 2010 tsx which k20 head would b the best (model and year)

[@jobata23]

Btw this is not a direct swap, the coolant passage would need to be modified and some other things
