Honda K20 vs K24: Which One is Better? 

Dude, we drive Honda’s, pricing is always an issue 😂😂

The real question... gallo 20 or gallo 24

K20: Im better K24: Nah, im better F22: *hold* *my* *Vtec*

I always felt that a K20 is best for boosted applications and K24 is best for N/A applications. K20 has slightly more cylinder thickness which helps block integrity good for lots of boost and revs higher which is good for a wider power band on boost, and the k24 has extra capacity which helps give a meatier mid range for all motor setups and a potential for higher compression due more stroke.

I don’t drive a Honda. I just wanted to learn more lol

K24 Heads have relatively poor flow, I believe the intake valves are smaller. Also, you guys didn't mention but there's a golden nugget K24 that had a crankshaft with fully weighted counter weights and improved block webbing, as well as other small improvements all around. I'm referring to the 06+ TSX's K24A2. The Odyssey and Element blocks are pretty comparable but the 06+ TSX crank is the superior part. The head also has slightly more aggressive cams but they're still hindered by the lack of flow potential from the valves. Yes the counter weights make the crank a few pounds heavier, but the high end vibration stability is a well worth trade off, plus its not like a good 8-10 lbs flywheel wont counteract the extra rotational mass/ inertia. If you grab a K20Z1 RSX-S Head and slap it onto a 06+ K24A2 TSX block, you've got the best combination possible. Throw some cams, springs/retainers, Pistons/Rods, along with a tune and 250+ whp is easily possible, if not pretty casual now lol

I would say that are probably the best 4 cylinder engines ever made. Best blend of reliability,tuning potential and price. No wonder they are swapped in everything.aftermarket is also huge for these engines.

Love your breakdowns man! Very informative and love your pace and delivery. No fluff or BS. Excellent stuff!

My cousin had a k24 bottom and k20 head, that thing was insane

Neither, K24 Frankenstein with a K20 Type S head and a 6 speed LSD Type R trans. Ultimate Honda setup.

The K24 is a taller block due to its stroke. That can be a problem where space is limited. Hood or oil pan clearance can be an issue.

K24A2. I have currently just installed one in my 1989 CRX. 6 speed LSD transmission. 👍

K24's are about to get super cheap in Canada, 2007-11 CRV's rear sub frames are all rotting out and being condemned.

Been wanting to build an ef hatch for almost 20 years. A couple years ago I finally got the car for a good price and just last week I got a salvaged 2013 civic si. Can’t wait to figure out how to get that k24 into that ef. I have a feeling that 205 hp and a 6 speed are going to be amazing in that little civic.

Awesome video man. So much to learn and knowledge to gain about cars, engines etc. Keep up the good work. Cheers from New Zealand.

I remember when a k swap just started. I was part of one of the first clubs to have a k20A jdm swap in an 95 EG! It was amazing!

I have a 14 Si and I’ve had B Series cars. A also had a friend who had an RSX-S. I love the low-end grunt of the 24 but the 20 is so much more fun with the more pronounced switch-over and 8k redline.

Being a guy who loves his dads DC5 great video. You need to do a video on EJ vs FA engines in the Subaru ! Your break downs are concise and straight to the point awesome stuff

Thank you for making this video. I still have so many questions about what my choice will be but this really helps break it down into a better decision making model. Thanks again!!

I can't watch this because I have to study right now. But I liked your video because I love this substantiative conversation. 😃😃😃

I just picked up a k24a2 for my del sol, cant wait to swap it in!

I had an 04 element EX that I totalled by hitting 2 elk in September last year but the engine still ran great just a lot of body damage to the front and now have an 02 rsx type-s finding out the k24 bottom+k20head would have been great I should've kept my element when I was paid out by insurance and taken a cut on the payout and combined the engines! Damn

Good job with these easy to understand videos and thank you.

I subscribed..because it's an excellent video. I do not own a honda but have always wondered about this. I'm a b14 nissan and L30 altima owner. But love the video.

A K24 with a reflash is a fantastic engine...from 2000 rpm - 7600, there is no let up til it hits the limiter, just pure power...and that is in the heavier accord

Fantastic video. I’ve spent 15 years around K-series Hondas, and I still learned some things. Well organized and concise information. Nice job!

It's 2019, those engines give me so much memories, thank you for making this video I'm thinking about it again

Second video I've watched and they really informative. Subscribed I have

I’ll go with the k20 because of the high revving

Very good! Lots of info! I have the k24/k20, and its boss

great video very comprehensive and well spoken thanks

Finishing up my k20z1 turbo swap in my dc2 today. Nice video

A k24a2 with a simple type S oil pump is loads of fun and u can rev to the sky!

One thing you mentioned at 4:00 is that the k24 from element/accord is preferred with a head swap. You overlooked that you would need to change the pistons out because the accord/element ones would hit the valves on the k20 head. I have heard more about people using a crv block and swapping parts off a k20a2.

So clean and easy to understand man 👏

Great video. Straight to the point.

loved the K24 I had in my 17 accord, but the CVT ruined the entire experience. also noted that the intake manifold was on the fire wall side while the block had the 4 exhaust exits built into it and lead to a singular exhaust exit. it was kind of odd. just switched to a 19 civic sport 6MT. couldn't be happier with my decision to get the K20 instead of the 1.5T, especially with soflo weather.

I'm doing a k20 swap and a turbocharged k24 into Pontiac Fiero's. I am trying to learn all specifics about Hondas. I cant let all the k swapped MR2's have all the fun! These engines have so much potential, its crazy!

You should cover the newer k series heads and how their limiting in every application including turbocharging.

Great video, I already have the amalgamation, Displacement and how to get more power in my head, As dude explained, 24 A2

Great video! The K series are my favorite 4 cylinder engines without a doubt

I reminds me, back in the day import guys used to talk about b16 heads on a b18.. or something like that

Just discovered your channel. Love these comparisons! Would you consider going old school and comparing the buick 455ci to the Pontiac 455 and the oldsmobile 455? A threeway comparo would be cool!

Need a k20 vs f20 vs k24 vid next. Loved the video.

K24 with k20z3 head seems to be quite strong. No expenses spared on internals, 12.9to 1 fully balanced bottom end, h beam rods and all arp fasteners, recommend doing the s2000 oil pump upgrade. The k24 at 8k+ is quite a handful between gears.

My '14 K24 Accord is factory stock and it's impressive. I had no idea about the potential of these engines. Also the Accord has the 6 speed manual.

Ty for uploading this I just bought a 06 accord coupe that has a k24 in it

Great video !! You should do a video on VR6 Engines 12v Vr6 2.8 24v Vr6 3.2 Vr6 Either way Great video i just Subscribed

I'm tooling around in my 02 crv with k24a1, precision turbo. Only thing that sucks is there is no aftermarket for 2nd gen Crvs.

Aww you missed the 9th gen Civic that had a K24. The extra torque made it a really nice daily driver.

Nice video. Using a K24a3 Accord for last 3 years. Really good for everyday use.

Nice info. Subscribed!!!

I drive ek with k20, k24, k24/20. All motor build. K24/20 all day best!! But when you build engine take care of all parts and build. Buy all new parts and do it like factory build. Best gear,tran, k20 gears only 6 speed from k24 and f.d 4.38. Best for street use. Cheers!!

I had a K20 in my RSX-S and my GF has a K24 in her Civic SiR and the K20 felt better when the VTec kicked in. Hers was fine but the switch over was smoother and not as exciting. K20 vote switch feels like a turbo. And the sounds at higher RPM sounded amazing.

I remember that a tuner in Greece swapped a K20 into an Austin Mini. That was a sweet build.

Very informative video. Will this set up fit a CRX or a Del Sol?, Also, there was no mention about getting the head sleeved.

I still got me a B18B1, non-VTEC and I still love it.

Thinking of the k20/k24 Any thoughts of my current setup. K24A2 engine TSX camshafts VTC camgear RBC intake manifold Civic Si ECU

Great video man , can you do a video on F series (the old one) and H series engine . I'm planning to switch in H22 for my 1st gen odyssey or find a way to fit a K24 in .

Very interesting comparison 😎 👍🏾 very informative ..

A k24 bottom and a k20 head. Best combo ever.

So can you explain why people do a k20/k24 frank build? With combining the k20/k24 can you still rev high on it?

Supporting your channel!!!

1 of the best if not the best video!!

Looking to swap a K24 into my Miata, making it lighter than an S2000 and torquier (is that a word?) too.

On a hp per litre ratio only the latest and top tier Type R, K series engines beat the older B series engines B16a, b16b and B18c (Gsr and Type R) versions. Goes to show the B is still formidable and relevant as what they lose in total power they gain by being the more economical engines.

Excellent video

My sleeper accord k24 turbo suprises all them V8 bios! Love it!

Great video, just one minor correction. "The K20 provides plenty enough power to push a lightweight Honda around...". As the overwhelming majority of Hondas are front wheel drive, you're actually pulling it around, not pushing it.

You're so eloquently articulate. 👍

I tryed an eg5 hatchback with a k24 swap. The hood was raised just so the engine could fit in. When the car was idling and you look at it from the ousite you could see the entire chasis where shaking because of the big engine :) For me the eg civic with k24 swap was more fun than a mk4 supra tt.

What about cranks/cams/rods etc. Do a comparison an all the best K series parts.

I owned an 04 K24a2 with a Jackson Racing Supercharger 6-7psi before owning my two K20's. The blown K24 was in a 2600lb EP3. I didnt use a k20 head it was fast and tuned well. However the K24 does not have the same rev matching raise hell feel a K20 does. I was jelly over my boy's blown K20a2 then... I went to a EG K20a2 swap and did IPS K2 cams, Eibach VS, handported head, RRC 87mm pistons, ported RBC, maxbore TB, RCrew header, 3" E, 3" ram air intake, kpro...just a bit over 250whp. Hybrid Racing cables too...Turned it into a downpayment on a home. Now I got a DC5-S. The K20 can be rev matched and driven like a cheap whore just a pounding away on a road course. The K24 likes it slow and ruff getting the job done. The K20 is like a really tiny hot piece of ass that like to be thrown around the bedroom and doesn't break under pounding. Just free up the mid-range and top end. Or do a 2.2L stroker with cams forged internals boom

I love my K20C4 👌🏼

Question, when I search for B18C GS-R forged pistons and rods what is the optimal rod length I should get there are 4-5 choices ...?

happy you made this video i plan on doing a 5th gen prelude swap. frist swap every was thinking about doing a j35a8 but i always loved K. K for the 5th gen is a header swap but i fill like it will be easyer to work on

thanks for the educational video. Love my 05' TSX! My only complaint is I just wish they sounded better :/ k20 sounds way better

As an old-school EF guy, I'm much more fond of the B-series for these reasons: - Rod linkage shifter. - cable clutch - more simple & practical layout for service - more noticable v-tec changeover!!! K series dont have the same "driver feedback" feel!!!!!

Nice video very detailed !!! 👌🏼

I was eyeballing a $500 longblock k24a2 swap for my carbd 86 crx hardtop...but only saw a k20z1 installed 1st gen... Thx for the vid

J32 gang!!! I'm older so I love the h22 and f20. When h22 came out people were hyped about it like the k series.

*_I like my FD2’s K20 better!_*

I need some clarification. So if you get a K24A2 from a 06-08 TSX, there's no benefit in using a K20 head?

Thanks dude. Much appreciated

Whats a realistic HP number for a K24/K20 head swap with a tune?

i bought a 07 k24a2 engine for 350 you cant find a k20a2 for less than 1000.. your backwards on your prices

I own a 07 tsx 6m and love it.. just hate that drive but wire response! But great engine and car soon to tune

I picked a K24A2 with ported head and Precision 5858 turbo. It revs to 7k RPM and makes an easy ~500whp. There are some reported issues using a K20 head and K24 block.

k24 all the way, i like the low end useable torque and throttle respond from the k24.

We used to put 396 heads on 454s back in the day, to increase the compression ratio (CR). Sounds like what your doing putting the k20 heads on the k24. For supercharged engines, it may be beneficial to put the k24 heads on the k20 to LOWER the CR. With lower CR, you can run more boost before having to deal with detonation issues!

Gr8 video. I go k24 with kept head mate

I would definitely not miss out on the k series .I will have both engine in my possession ❤🎉🎉

Where are you finding the k20 cheaper than the k24???

K20Z3 says hi.

I had been looking for this video a week ago)))) . I got a certain question, what is the difrence k24a3 (204Hp) and k20z4 (203Hp) ? And how it will be feels like - k24a3 204Hp with k20a oil pump and full exhaust?

Nice video !!

K24 is way cheeper then k20 man

K24 all damn day. More displacement and much more torque.

Starting to mod my k24a4 accord coupe. Cant wait to see how it goes.

What’s up buddy..what’s your opinion on K24z7 ..was looking at getting a 15 SI and if I get one iam going to boost it..your the PRO wanted your input..👊
