Why This Tiny Honda Engine Can Make 1000hp

We got our hands on a K20A from the DC5 Honda Integra to see what makes this one of the greatest engines Honda has ever produced.

Donut = We like cars, and we like making videos about cars. Hopefully our videos make you like cars too.

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

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

[AON]

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

[Sr.Fluffioso]

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

[Coooastal]

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

[reemeruxd]

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

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).

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 😂

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.

[Plimpert]

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!

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.

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.

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!"

[streetstormer]

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

[LunaDecksTCG]

I have an idea make the Subaru's reliable and put that motor in there. Make a Hondaru

[cwadlow]

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

[naerkode]

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?

[alexmackenzie]

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.

[lebronjames]

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

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