The Differences Between Honda K-Series Engines

The K-Series engine can be found in countless cars from Honda and Acura’s lineup. It has been found in vehicles ever since the year 2000. Since then, there have been many revisions along the way. Some of them produce more power than others, some of them are more efficient than others, and some of them rev higher than others. In this video, I go over the main differences between the K24A and the K24Z engines.

My advice if you want to build a K series engine is do research a bunch prior to purchasing anything or making any moves. There is a bunch of information out there, especially if you have a K20A/K24A bottom end. It is a bit more complicated if you want to make a Frankenstein K24Z with a high flowing K20A/K24A cylinder head.

[@erikk27a]

All u gotta know is that the best k series is out of a 06-08 Tsx. The k24a2. Amazing engine.

[@milanmastracci]

Thank you guys for correcting me. The "VTC actuator" for the exhaust is not what I said it is. Honda only has VTC on the intake sprocket. If you have any ideas why the exhaust sprocket is thicker and not just a regular gear, please enlighten me! The more ya know :)

[@chaserevstuning9271]

It's cause it helps with balancing of the cam so when vtec happens it's not harsh and is more smooth.

[@jeffreydeleon5630]

Exactly the build I want to do. I have a 09 tsx with the k24z3. I have a spare engine at my shop. All I need to do is source a k24a2 head which isn’t a big deal down here in so Florida. Looking forward on this build 🙌🏼

[@SERGMOTIVEGARAGE]

Bro, honda doesn't use a VTC exhaust cam gear. VTC actuation is only controlled on the intake side which is why you can switch from 25 degree VTC gear to the 50 degree gear. Only way you can change cam timing on the exhaust side is with a adjustable exhaust cam gear.

[@milanmastracci]

Maybe I'll have to rip that cam sprocket apart. I am going to be switching to a 40 degree gear for my intake I know that. I'm still learning as I go. I know that the fuel in my area will be the only drawback since E85 isn't readily available.

[@vladdutz20]

Good comment, i have pointed that above in a comment, it is easy to spot that vtc is used on the intake side only because when you removed the camshafts from the k24a2 block you could see that there are 2 oil passages under your left hand for the intake, used for advancing and retarding the timing, but only one passage on the exhaust side used for lubrication. Also if you inspect the sprockets closely you can see that the intake one has a ridge because it is made of 2 sliding pieces, whereas the exhaust one is a solid block, even if it has about the same thickness. It is thicker for balancing the 3 lobe pairs that are heavier than a single cam design

[@HarleySLA]

I agree with you, on the engines we're looking at here. But Honda has definitely used variable valve timing on the exhaust side in other engines. The reason why was to eliminate the need for an EGR. Learned that at Honda school, kind of an interesting approach to emissions. Not nitpicking your comment, just thought someone might find it interesting because I definitely did when I learned about it. Cheers 🍻

[@argen809]

I think you’re gonna need some drag cartel cams if you want 300 or at least some higher compression like 12.1

The Frankenstein only runs into problems without a tune- it drops your compression about 1/2 a value (12.5:1 vs 12.0:1)

[@Nebbia_affaraccimiei]

still mismatching head and bore it's not great. machine the head to suit, then yes :)

[@noblewon3507]

Yeah the k24a2 and k20z3 head is a pretty bad ass set up. Tune is the biggest factor when running it. Got to upgrade the oil pump at that time or the k20 head is basically useless because the k24 doesn't have the reving ability without it. so there would be really no sense in pairing it with a K20 head unless you upgraded the pump as well. Even then you can't get the full potential out of the k20z3 head , you have to be careful of the VTC degree.

[@corbinyoung5320]

@@noblewon3507 what is the VTC degree

[@noblewon3507]

@@corbinyoung5320 the VTC is the gear on the intake cam. It's also known as a cam phaser. If you're not running the right degree you could possibly make contact between the valve and pistons

[@redcatxb125]

Good info! The crank pos sensor difference is pretty reminiscent of the Honda H series DOHC motors, on those, the usdm obd2 h22a4’s use a similar setup except the crank pos sensor bolts onto the oil pump which is bolted to the front bottom of the block. On jdm h22/23 they use a crank angle sensor which is in the middle of the back of the block reading the crank between cyl 2 and 3. For that reason any jdm h series swap will likely require transfer of a usdm oil pump for the CKP sensor

milanmastracci, great content as always! One piece of unsolicited advice is to purchase a new RBC VTC to ensure you don’t get the dreaded VTC rattle on cold start. I bought a used one for my TSX and encountered that rattle a couple months after the install. Call it cheap insurance, but buying a new one could save you some headache and will net you more low to midrange power over the stock 25 degree VTC from the TSX. I believe the VTC from the 09 TSX is a 50 degree one, so you may not need to modify an existing RBC VTC to 45 degrees.

[@milanmastracci]

That's a good idea! The only engine parts that I will be reusing for my build is the crankshaft, the engine block, the oil pan, the cylinder head, and the cylinder head tower. Everything else will be upgraded, including the VTC actuator. I have a custom one going in this engine.

Awesome vid and loved the intro. Correction about the K20Z, the Z1 was introduced in 2005 on the RSX-S

[@millenniumzeek]

also, the K20Z3 from the 2006 Si lost the manual throttle cable for dbw, gained RBC intake manifold and balance shaft that robbed high rpm HP.

I have a k24z1 in my 07 crv. And my head gasket blow because i was driving it overheating for like 30 minutes. I would like to know if my head got warped and if the k24a got the same plugs as the z1

Fantastic video chocked full of very useful information. This is important to me. I have an 02 accord LX 2 3L with 5 speed manual trans. The engine has 197334 original miles on the odom. The engine is starting to burn oil and every month I'm having to add a quart of Mobile synth. High mileage oil. My engine is the ULEV and I want to have more NA Power. This video gave me the info I need to begin my engine upgrade towards "Mo Power Baby" Thank you. If you have any info you feel I need Please respond I value any and all advice or input. FYI I am originally a Chevy Camaro Fan boy and owner Honda cars I've have owned never ever let me down.
