This doesn’t ruin the fact that Hector’s running 3 spoon engines…

As a car noob I really appreciate all the explanations and the diagrams+animations you guys put in your videos!

Let’s be honest - Zach and Jeremiah are the best combo on donut. Two great personalities that keep us entertained and things interesting!

I love the fact that they actually show sometimes things don't go according to plan whereas big shows never show the issues you run into

Engine analysis videos are easily one of my favorite types of videos y’all make!

Shout out to the video editors and animators. All the titles, infographics and sfx were exceptional on this episode.

Can I just say that for someone at the age of 32 just now getting into fast cars, this channel is the absolute best. You all break it down and use pictures and cartoons lol it’s the best. Finally got my Silverado how I want it. Surprisingly the JDM scene looks like a lot of fun coming from a country boy 😂

5:29-5:42 I had this same issue putting together my LS engine less than 4 days ago, using an inexpensive ratcheting ring compactor. 2 things in conjunction that I found worked were: 1) ensuring the piston was centered both vertically and horizontally in the compressor as I tightened it, while ensuring at least 10mm of piston skirt stuck out the bottom so that when placed on top of the cylinder, I could use the skirt to help guide the piston into the bore and center the compressor above it. 2) when inserting the piston, I had to give it a truly solid thwack so that it would fly out of the compressor and deep down into the cylinder in one go. Applying oil on the outside diameter of the piston and rings, and the inner bore of both the cylinder and the compressor helped out a lot in this endeavor (and no, I would never install pistons into cylinder bores that weren't pre-oiled first).

Zach and Jeremiah are definitely the best guys to pair up on an analysis video like this. They both have the best understanding of actual mechanics amongst the guys at Donut.

More like this please! Jeremiah’s attention to detail with the concerns over the tensioner was such a related thing to leave in, better to spend the time and double check before it’s in a car. Can’t wait to see it in the EG!

Thank you Mr. Burton and Mr. Jobe for breaking down these videos so well for someone like me who don't know anything about cars to where it is so easy to follow along and learn so easily. You guys are great at what you do.

I love these videos when you explain certain engines. I’d love to see a 4A-GE engine video!!

Just look at the quality of those cast aluminum parts. They look flawless. The Honda makers and quality control are just perfectionists, so proud of their craft. I work in a hospital laboratory and I can appreciate this greatly, because for me making a mistake is never an option, it could result in someone dying. Taking this pride in the quality of the things you create has a powerful effect on the soul, and I’d recommend anyone to try it.

Mike at Stanceworks being the benchmark for crazy K-Series Swaps makes me happy!

I don’t know much about engines, but you guys make it really easy for me to follow along and learn about how the engine works, so I appreciate that!

When doing torque turn, just use the bolt head. 360/6 is 60 degrees. If you just mark the socket at one of the 6 points, then mark that girdle at at the next point on the bolt. Just turn the bolt until the lines meet up.

Looking forward to testing it on the $500 Civic😅. Could be interesting to see how the car does since it has new suspension and all?

I can’t describe why but Adam is one of my favorite donut personalities. Not always shown on camera but clearly knows a lot and works hard

Trowing this out there, I'm pretty sure you should have put the oil pan on last. You never know if you might drop something in there while working on it, and the front cover is designed to be installed before the oil pan. The way that the oil pan seals would work better against the bottom of the front cover, by doing the front cover first.

In my book, these engine rebuilds that donut does will allways be the best videos donut can make

Jeremiah and Zach are the bread and butter of this channel. Entertaining as hell and they actually know what they’re talking about.

I love when y'all do this type of video. Tearing it down and rebuilding it better. Along with some charisma, you guys got "it!"

Honestly I feel the K20 should go into the $500 Civic. Make a man entirely new 3 or 4 part series about how a cheap car could be built into some crazy type of beast. Let’s see the full potential of that $500 Civic..

These teardown videos are so cool and so fun to watch

The boys and girls at Donut have really outdone themselves with this one. From the topic itself, the wealth of knowledge and passion on display, to the incredible animations, and perhaps my favorite thing of all, the ad progress bar (thank you so much for keeping this alive, I'm sure it's not easy), I am truly blown away. Donut Media is hands down the best automotive enthusiast channel on UKposts, maybe even the best channel overall. Much love and appreciation.

The closest thing we could get to the DC5 Type-R was the 05/06 Type-S. The K20Z1 was so close in performance to the K20A that with a few mods it’s indistinguishable around the race track.

I had a 216K mile K20A2 in my 02 RSX when I sold it. I bought it new and used it for a daily driver. Always running pure synth oil, it kept running better and better. It would even run strong on regular gas with no detonation.... good spark knock sensor I guess... I should have kept that car just for the engine but didn't know these could even come close to 1K hp.

So good to see you make videos about vehicles again!

Bro that Jetta didn't stand a chance on that highway pull. Straight GAPPLEBEES

I love it when you guys do Honda stuff

What most people don't know about compression ratio is that it works on piston while going down also (intake) The piston being closer to the top of the cylinder creates a greater vacuum force while on the intake stroke. This is why big cams work better with high compression ratio - they need the momentum of fast moving air to wake up the cams.

You guys really make quality content. Within the last 2 years, I've really consumed quite a bit of cartube and Donut is easily one of my favorite outlets. I would love to maybe see a video formatted this way, but about why Dodge's Hemi Engine is so infamous.

These two dudes are super knowledgeable and super entertaining - big ups to Pumphry for hiring them. Donut should start a race team and document the inevitable ups and downs. Porsche Cup is calling you boys.

It would be extremely cool and amazing if you guys could sometime build a 1000 HP engine over the course of a series or something 🙏. It's always been rather shush shush in terms of details beyond broad strokes (at least on UKposts in my experience).

I had a 2005 RSX Type-S. It wasn’t exactly the engine from this video, but that car was a blast to drive. It LOVED being near redline and never had any issues with it. I miss that car so much.

Major props to the graphic artist on this vid, super informative and clear to read.

This is such an incredibly well produced informative video. I can hardly believe that content is being made this way by regular ppl, that is 1000x better than stuff being made in mainstream media by 100 billion $ corporations. Stuff like this is truly the way of the future for media.

Can't wait for it to be in the EG hatch rippin around tracks.

15:45 - I see a little green honda it would fit into nicely.

The edits, animations and explanations are just beautiful...

I enjoy the mix of tips, tricks, and struggles. Because we all know when it's said and done 80% was struggle.

Loving the technical content guys! B2B and money pit are what got me to subscribe. Hoping to see more stuff like this on a regular basis

The cardboard bolt sorter is freaking genius!

Amazing attention to detail. Love this channel ❤

As a fan of your Money Pit series, I really enjoyed this video. :D I'd love to see this turn into a series that covers popular motors.

I have couple cars and have had a few more with K20's and K24's I've been impressed with every single one of them. In my opinion they are one of the best 4 bangers ever made. Great video, guys. 👏 👏 👏

I love an engine with inline cylinder configuration, I've just always had great luck with them from the 22RE from Toyota to Ford's old 300 I6 I've never owned one that gave me issues.

Great video, just starting to learn about cars so someday I can build One myself 👏🏾👏🏾🤷🏾‍♂️

I hope you guys realise you set yourself a high bar with this episode, really well edited and everything.

Would love too see a series where you guys build a car with 3 beginner mechanics and record the journey along the way!

I would install the crank and girdle plate on a flat table vs the engine stand. Love me some k20 power!

Honda makes engines that run well but also that just look really tight and tasteful, with well designed placement and interconnectivity of all components.

these are the best kind of donut videos. Entertaining and I feel like I learn something cool in the process. These two are my favorite hosts, always fun and seems like they are the most knowledgeable

Jeremiah seems hella pissed that Zach got “sick” lol

2:40 I think it's quite the opposite don't you think? Smaller is for rpm, bigger is for torque since it has more room for explosion and producing much more power.

Dual VTEC....when low RPM you can set it for 280 degre cam. In high rpm you give itu 330 degree cam profile. So it become an afterburner piston engine since it install turbocharger. Just make sure your valve and piston are not melting.

Not only do these videos show the unique way engines are made, but the fact that they don't dumb it down makes it so much better. Education and entertainment all in one. Keep up the great work guys 🤘🏼

I love these rebuild videos, I learn so much and it's really well edited and produced with great personalities, flow, and educational but fun content. Watched a few videos way in the past but got more consistent when HiLow first came out and I've learned so much about building, fixing, and modding. Haven't done much myself yet for my car since I don't have that many tools or time to make it easy, but I've been working on my bikes with more confidence.

Reminds me of TRUCKS from back in the day! Good stuff boys keep it up! 👍

Algorithm boost comment lol

Something I haven't heard you mention, the reason that engine is so used over other k series engines that are similar is the ECU for it was the original base for k tuner and those are cheap compared to the other variants with similar internals. Similar goes for the k24s from that year range being as used that only require two connectors swapped compared to back grading the ECU and harness like later engines in that series require for kpro. Other you did a good job explaining the basics for new car enthusiast.

I'm not even a Honda boi but if my 86 goes I'm totally planning for the K swap cause I love the balance of a boxster motor but 500+hp in an 86 chassis would be INSANE

I love these videos. They give off such a nostalgic vibe. Feels like watching the old school hot rod tv shows 😂

I just bought a dc5 last Saturday Firs time I've ever owned an integra. I was very chuffed to watch this :D

the trick to the ring compressor is you want to seat it inside the block a little. If you get the cheapo ratcheting ones this works great cuz you can push them in axially and they sorta "spiral" out, giving you a nice edge to stick into the bore. the edge being in there helps transition the rings. DO NOT hammer on them or force them if they're snagging, you can bend or snap the rings.

Yessssss!!!! I’m here for all the Honda Boys that we fought our friends and family saying that the B and K series special K20A were one of the greatest engines ever created!!!! I been waiting for a Honda series on Donut and my Teenage self is going crazy right now!!!

K series is awesome. Been in production since at least 2001 so there are parts for days!

These engine rebuilds videos are great. Cant wait to see more

My first car i ever bought was a 92 Integra 3 door with the B18 without VTEC. It wasn't the fastest thing but i had it set up like a go cart and it was probably the most fun I've had in a car.

I have JDM K20A sitting in my USDM 02 EP3. Even have the 6speed LSD too. ❤

THIS is the kind of content I love from Donut

Literally have been working on my Teg a lot lately and honestly thank you guys for making this video. Really helps me on my research!

My friend had a 94 civic hatch with the K20 in the early 2000s and damn it was fun. I think he had the rev limit at 9500 rpm. It sounded great.

Epic video as always @Donut , one of your best! Just one thing I'm still not clear on - What's the specific thing that differentiates the K20A from the other K's? Is it a different kind of I-VTEC from the K20B & K20Z? Or is it just the magic combination of all the best bits of the rest? Lastly what's that sick DnB track at 14:10? About time you guys stateside caught up with us :P

Hello Donut team. I love your channel and content. My suggestion would be to put the K20A motor into a Subaru BRZ, the one with the older body style! The car has amazing suspension that’s overdamped and handles great. It’s also compact and the engine bay would be proportionate to the K20A engine. What the lacks is power. And the boosted K20A would be the powertrain it needs and will turn the car into an absolute rocket 🚀. I’d also put 225 tires on the BRZ with some nice aftermarket wilwood racing brakes. Add couple of aero mods. For tuning the boost, I wouldn’t start at 1000bhp, perhaps 500 bhp is more than adequate to test out the vehicle on a track. Thank you for producing such great content for us car enthusiasts! Looking forward to the build!

Love this. Make this a series. Would love to see you tear down the legendary 4G63T next!

I love waking up in the mornings to watch my Daily Dose of Donut.

Love this vid man good stuff!

These teardown videos are so cool and so fun to watch. This doesn’t ruin the fact that Hector’s running 3 spoon engines….

I would love to see an episode on the rotary 13B and maybe bring back Aaron to really go in-depth into the engine.

Loooove these longer, technical mechanical videos!

I have a K24 in my honda element, All it needed was a cold air intake, Exhaust mod, And a tune to get to 350 HP from a stock 160

Back in the early 80's Renault F1 engines were factory tested and adjusted after assembly. They were 1.5 liter turbo engines. The test and adjust run on the Dyno was limited to 15" max and the minimum acceptable power was...1500 HP. After 15" the engine was either "good" or ... scrapped... My point is, it's relatively easy to get very high hp from an engine. The only valuable aspect is how long it will last.

I used to have a EJ6 fully built D16 SOHC turbo that I built with friends and man that thing was fun to drive, the dream was always to upgrade to a K swap motor, but this was like a decade and a half ago so it was kind of expensive then. To see the prices now, it makes me want to build another one again. I think I would easily go all-motor though in a lighter chassis, the all motor NA just slaps and feels so much more raw and visceral IMO.

I'm very excited to see what comes next for this Honda. Though I am a little sad that we won't get to see you slap some turbos into the old engine.

Now the question I have is can you hook a automatic transmission to it! I have a v6 09 escape I thought I could get one of these engine and do same set up and put it in my escape.

I had one of those K20s, with turbo in my CRX. God I miss that car.

You guys put the K20A in a Honda fit😁😁😁

I'm loving these engine builds. I like when you go through what is different from the run of the mill cars that aren't build for power. Thoughts on doing a rotary? Maybe a 13B REW?

stuff it in that 3rd gen prelude in the shop, i have a 3rd gen i’ve always dreamed of doing a crazy k series swap

Man they should make a video about the 4g63 i am very interested in that engine

I’m so glad you guys are doing build videos again! I might be wrong but felt like there was a bit of a dry spell there. Thank you guys for all you do!

I’m so happy you guys are doing Honda builds now

I love these kind of videos and want to learn more about cars and engines in general and want a personal project car in a couple years, where can i start to learn?

These two transformed donut for me. I love them and they are the core of the show for me

Awesome guys! That engine in a MR2 Spyder hardtiop would be spicy, the sound in that cabin of 9000rpm alone would be insane... then there's the tight handling low center of gravity and fast acceleration from the light chassis. Great video, im sure whatever car that engine goes into will be incredible.

You guys should do a VR6 tear down next, or an EA113. I feel like Jobe experience from ECS would come in handy.

I loved my D16zC motor....It didn't like just more than 8 lbs of boost though w rebuilt stock internals..upgraded the bearings rods and pistons a bit after the first slung the 4th rod bearing and second blow because of the 4th piston again because it ran hotter than the rest......I always wanted a B18C3 though as an upgrade but the motor I had was so cheap and easy to rebuild......2.5 inch exhaust....B&m short shifter....Fluidyne radiator, walboro 255 lph fuel pump....I forget the company but my ignition was all upgraded.....Fuel rail, injectors were also done, stock trans....But stage 1 clutch...did some other upgrades but I loved my civic.....Greddy turbo kit...Blow off valve was by....I forget but they told me it was for Subaru even though it was a universal kit....oh turbo XS...My next car was a 2004 sti w more money in the driveline than my house cost....Made over 40o hp at the wheels and 370 lbs of torque....26 lbs of boost all day long...custom built and tuned....Loved that thing...can't believe I sold that and my custom Honda CBR F4i....but was making 100k a year and had a lexus is350 awd and an suv and bought a house at 29 years old.....had 3 kids...went to great wold lodge and had tvs and xboxes in every room....all was great until I caught a coworker co manager of mine embezzled money and when I found out he had upper management lay me off because they were in on it...since then my life has been homeless basically...I pray karma takes them out to this day a few years later..

The first piston you seated.. keep in mind you have a crank in there 🤷‍♂️ We can only assume you remembered that and rotated properly. The first massive below he gave.... You don't need to go that crazy. You don't want those hardened rod bolts to smash up against that beautifully polished crank surface.

ya we need more of these there some of my fav. vids. ever sense they did it with the zs and subies closest were going to get to science garage miss that show so much. and def put it in the eg hatch as a new money pit car
