Miniature 4 Cylinder Engine + Gearbox! 

To me....that engine sounds better and healthier than the v8 engines

Back about 35-40 years when I first got into the gas powered RC stuff this stuff was a thing of dreams. It's crazy how far the hobby has come. I would have given a million bucks for something like that when I was a teenager lol if I had it. I can't wait to see what you put this in it's going to be really awesome! Keep up the great work Johnny!

Id love to see some of these engines in a drag racing league setup. A class for 4 cylinders, V6, V8, and V12

Wasnt expecting the glass sides, that was pretty cool. Great sounding little engine, 3D printed metal trans case is pretty slick too!

It will be interesting to see a car with such a motor and gearbox

Please supercharge it

It sounded like there was something off with 2nd gear, possibly slipping? Really cool setup though, its nice being able to hear these engines under load.

Things sure have come a long ways from the old days of the OS single cylinder 2-stroke engines, lol. Transmission is incredibly cool. Pretty amazing what can be made with those metal 3D printers.

That is so cool....I want to see the rpm reading going thru the gears!! Another great vid Johnny.... keep em coming!!

this motor sounds great, and the throttle response is awesome can't wait to see this in the car.

This is just so awesome to watch. Am disabled so struggle to do my hobbies but thankfully able to watch others.

love the longer operational video. very pleasant to watch great video and audio. Please keep these parts of the video longer in the futuren for other engines as well please :)

no music no extra just straight to the point love it man

So sick....your revving technique has improved so much..... How sweet the sounds are while shifting

Καλή χρονιά με πολλές τρελλές κατασκευές!!!

This dude never fails to impress me with hobby grad RC content even if he fabs it him self

This is the best sounding 4 cylinder miniature I’ve heard.

Sounds really good and love the cam setup when idling 👌

Would love to see a tiny turbo on that thing.

Best sounding miniature engine iv ever heard, this is outstanding work

You can see the smoke from the heat it gets you did a good job at fixing a problem the company didn’t fix

Amazing Sound and nice Gearbox ! ❤

I agree, Johnny please just be the Johnny we need you to be. .this is bad ass stuff.

Great video amazing att to detail you are blessed to have this much time on your hands for a hobby

I don’t know why but this one is clearly the best sounding engine you got ❤

That thing sounds amazing... wow.

Amazing, well done !

こんなにリアルな模型エンジンは見たこと無いです。イグニッションプラグを使い、トランスミッションまで再現してラジコンするとは驚きです!

That is the coolest looking miniature gearbox ever

That thing sounds so much better than you would expect. I would love to see it in something like an RC 1/6th scale Legends race car build. It would be perfect.

This thing sounds sick!

Literally Amazing

Probably the better sounding of all the engines you have had tbh

as usual, JQ90 has outdone himself once again. what a freaking legend. what other creator on the tube could ever just crush it like my boy here? anybody? ya thats what i thought too. true proof right here that quality can wreck quantity any day of the week. id say keep it up but, Duh.

Really nice engine sound and it revs very good. Think they getting better and better with these small replica engines 👌🏻

this is the best sounding miniature engine on your channel i think.

Wow it’s simply amazing what u build! Sounds so good also! Keep them vids coming!

Amazing gearbox! And the glass sides were good addition to the whole assembly. The engine idle sounds almost like my dads ford escort with 2.3l ohc without exhaust but little bit higher while big engine sounds deeper

💙 Give this man a Royal Salute

I think this is my favorite engine from the bunch

watching this video my eyes was sweated a little bit remembering the day that my father told me how a car engine works. Thank you so much for this feeling

That must be the best sounding micro engine I’ve ever heard 😮

Nice! I love the site glass covers!

Way cool Johnny Happy New Year 🎉

Happy new year brother!

That sounds so good 😍

JohnnyQ90 Is a Genius.

That is a very nice combination, seems to run very well. Tks

Little buddy goes braapppp 😮😮😮😮 Must be pure satisfaction working on these stuff

wow! the amount of ideas that come to mind for rc's

Thanks for sharing 😊👍

that new exhaust you put on sounds so good

thats one sweet sounding little engine.

Amazing stuff to watch.

well you finally did it good for you Vince

At the end it sounded like a c4 quick shift shifting very nice!!

You are a engineering genius, just found your vids ,subscribed straight away,will be following your projects with great interest, keep it up 😊😊😊😊

Need this in a drift build💯

Cool vid sir. Been a sub for a while. Keep it up! Look forward to the next one!

Wow! sounds awesome 👌 ❤

That's pretty cool man😎

I Love This! This So Cool! I Would Love To Have A Small Engine Like This!

Happy new year 2024

Perfect. Need chassis for that

Great video. 😃

That's so awesome man! KUDOS. Now I want one on my RC crawlers! 😂😂

One of these would be great in a RC Boat. Cooling could be handled with 'Raw' water pumped directly from the pond or pool. With a gear box for forward or reverse operation

Johnny you’ve done it again! Been watching your videos for about 5 years now and loving all of it! Keep up the good work we all appreciate the high quality content you put out brother :) I’m curious to see what comes in the future for your channel as far as builds go! As a man of few words I don’t expect a reply but do you have any plans for the 2 rotor? Bringing back the centrifugal blower? Perhaps a turbocharger? In the past few days I have seen a few videos on small scale engines that have an electronically controlled Nitrous kits! Much love, peace and wellness to you and your family!

Just too frikkin' Cool!

I cant wait to see what youve got in line for this creation. 😮😊 how does 1 person get soooo damned much done!?! To say "Impressive" is doing you a massive disservice

I like how much more fuel flow there is on load.

Another so spon!! Good fortune!

That progressive spring shifter is trick. Simplicity is king.

Absolutely insane what these manufacturers are putting into these small cars. Weirdly enough the only one I haven't seen yet is a miniaturized boxer engine, like an EJ subaru engine. maybe someday!

This is so cool 😎 need to mill a turbo on the lathe 😍

Pretty bad ass man.

Dang that little in line 4 sound mean !

Happy New Year!)))))

Надеюсь в скором будущем мы увидим конечный продукт твоих экспериментов… Видео👍👍👍👍👍👍

Yo this sounds so good. Sounds like a honda k24 drag car like the boostedboiz run.

i think it will be great if u use this for RC....engine sound was awesome!!!

That 4 cyl sounds really good! Project idea: I'd love to see a hydroplain boat with one of these Toyans. Preferably the V10! Seems like a perfect platform for one these engines. I bet you could make a sick body out of aluminum sheet. JS. Happy new year bro!

Working great

It would be a challenge but I’d love to see a FWD RC made from this engine! Would be awesome

Love it, amazing sound ! 😍 A good exhaust with proper chamber and great volume should be nice for better rev, more torque, and a better sound too (less tiny) :)

Wow,that smaller pulley wheel sure did add A LOT more pressure to the coolant-line! Great job on that! LOVED the clear windows You stuck on the sides too! And MAN,that think shifts VERY SMOOTHLY even without letting up on the throttle too!!! Great video!!! : >)

Too good just love it❤ and please put set up in RC truck

inspection ports are sorted 😎👍

Awesome video , a 5 speed transmission would be great 👍

Reminds me of Toyotas new i4 engine for their truck line. About the same displacement! 😂

From humble opinion, I believe the transmission should have a lot more grease in it or an extra pump to circulate & cool the transmission fluid as a lot of people I have seen by adding a radiator for the coolant & engine oil.

Amazing 💯

Now we need to make the frame and body out of metal, and it will be perfect ❤

This little four-pot engine has a pretty angry sound. Pleasant.

Very cool

That's awesome

Next up on Johnnie's list of things to do, create a billet johnny shrinking machine, so he can tear around the neighborhood....

That engine sounds so sweet🍰🍰🍫🍫

Best performances

Straight 6 would be cool.
