4Piston is the king of the Honda game, their parts are the real deal. My first experience with a 4P product was years ago when I bought a used 4P CNC B16 head off a forum to use in my modest B20Vtec setup. Prior to the head I was running a stock P72 casting and made 218whp and 146wtq. The setup was a 84.5mm 12:1 CP piston/Manley rod B20Z, stock P72 head with Supertech springs and Skunk2 Pro2's, Skunk2 intake manifold, 67mm TB, Hytech header, Thermal 3" exhaust and an S4C LSD tranny. Most bearings, gaskets and fasteners were all OEM except GE intake gasket and ARP head studs, rod bolts and flywheel bolts. After swapping the GSR head for the 4P B16 head and retuning, the setup churned out 238whp and 156wtq. It was a blast to drive and didn't cost a million dollars to build. These days my all motor mill is a K24a2 bottom end, K20a head/cams, ASP header, custom 3" exhaust, Custom 3.5" intake, ported RBC, Hondata tuned. Looking to add some DDTech custom cams and a 4P head in the near future and break 300whp with a stock shortblock.
@@kevinhawley962Nah. A factory B16 head is essentially a Type-R head without the polishing. For serious all-motor applications, a B16 head will outflow a B18 head.
Thats two weeks in a row, where the craziest thing I have seen on the internet for that week has been about crazy N/A Hondas. The porn industry is slippin.
wow 500hp on a n/a four banger... amazing shit! I remember the days when to get to 500hp in a 4 cylinder you had to spend loot and have a turbo or supercharger. now I could buy a Honda shell dirt cheap and get this motor and be all in under 10k, that's awesome!
Imagine creating a legendary 4 banger that's capable of 500hp with no forced induction and have it demonstrated by F1 driver Valteri Bottas,, damn Honda is really on a different league!!
When I saw this I was inspired. I have a AMC 2.5L now I have a goal to try to crank every ounce of horse power out of her. I love the fact that this is sutch a small engine and it's creating such a large amount of hp.
@@moosahans4830 The new one is an entirely different car and engine despite what people thought last year. Sounds better, way more usable and enjoyable power band, looks way better than last gen, and now holds absurd speeds in corners that last gen simply couldn't last 2 minutes behind. Truly shocking if you get the chance to test drive one.
This is something i want in my 01 integra i currently have a k24a2 rbb-3 long block bt the build im seeing and hearing yes id love to put this all motor set up in my car as a daily n drag mad respect and props to this video very huge inspiration to me fully
Beautiful build, but no mention on the type of fuel to achieve those numbers lol. 91 pump for 500 n/a? Lol jk. I wonder if they use e85, C5 , or M5 or meth/alcohol. Would love to know.
Yeah that's the way the sport bikes works, with a throttle (intake) per cylinder, that's the way to make it a direct admission and increase the valve time, power and speed rpm!
You realize that these guys never said what fuel they used, don't you? They most likely used race fuel. Also this engine is a ticking timebomb because of the power output. The engine in this video probably has a ridiculous compression ratio. Supercars have big engines for a reason.
OneTT I'd like to see the torque lol. Hondas might be able to make as much power as a V8 but a 500hp V8 is a lot more reliable and cheaper than a 500hp Honda and a lot more torque.
I love cars, but I've never taken on a project car. I've got a tuned Audi S5, and I love it... But I'm thinking of getting a 4piston engine with a few drag cartel parts, mating it to a ZF 8HP, and swapping it into an MX-5 ND. There are a few other upgrades I want to add to the Miata as well; upgraded infotainment, custom carbon fiber interior parts, chassis stiffening components, wider track suspension parts and upgraded coilovers, pilot sport cup 2 tires on Rays TE27s, larger breaks, and OEM-look molded fender flares - all being the main components on my mind. Now, I know that the 8HP is an automatic, but I'm chasing a car that I can effortlessly throw around twisties and tracks, but which will also be efficiently comfortable on the highway. While you may have your opinions on styling and particular parts with similar capabilities, what do you think of my potential build list? Do you think it could be a recipe for success?
Yo I just watching AK’s video with that beautiful 4piston engine with the Red cam cover looking so sweet I just have to come and check out you GUYS 🔫🔫🔫🔫🔫🇵🇷👍🏼
for people who doesn't know this engine was intended for race use only. it not street able.it use race gas. so pls don't ask if this engine reliable or not as it will require periodic maintenance
The K24 should have been the base for the development in the new NSX. They should have taken that motor, and made it perfect.. you add that with the turbo hybrid AWD.. and that car would be AMAZING, it would sound so freaking good and the performance would be insane
I work for a forged aluminum piston and connecting rod manufacture .... we also build roots blowers but that’s besides the point. It often misconceived about making power at high rpm . When you do so it’s because of angular momentum . If you get a bunch of mass spinning fast it’s hard to stop. That often looks great on paper but you don’t really feel horse power while sitting in the seat driving. What you do feel is Torque, it’s what gets mass moving and sits you back in the seat , or it might be the Force that accelerates the vehicle . When you make 500 hp down low like say 5000 then you do so via big stinking cylinder pressers forcing the piston down and making a tone of torque . The math say 500 hp@ 5,000rpm= 525.2 pound feet of torque. So you see 500 hp @ 5,000 rpm is twice as much power than 500hp @ 10,000 rpm! It always bugs me when people state power numbers with out the rpm it was made at because just a horse power number buy it’s self tells you nothing about how much power that is.
Casey Hogan thanks buddy. I’m trying to find some one near me that’s good at editing to make some helpful vids explaining what I have been taught . Hopefully it will happen soon.
Misleading. Power output is ain't stranger to those Torque and Rpm, they are related ! You can manipulate the a amount of Torque producing @ the wheel by gearing in expense of reducing the wheel Rpm and guess what the Power didn't change ! Low end Torque low Rpm engine will perform the same as the high end torque high Rpm engine as long as you keep 3 variables unchanged 1) The power output quote in Hp/kW or whatsoever 2) The powerband area (you can't compare an engine with a narrow powerband to that wide powerband engine) 3) Both must have the same amount of gear and same amount of torque multiplier through entire gear ratio (e.g 1st gear engine #1 max torque 100Nm x 2 = 2 times torque multiplier with 2 times speed reduction vs engine 2# 50Nm x 4 = 4 times torque multiplier with 4 times speed speed reduction. Make sense? One more thing. Torque isn't always a force acting on a surface (piston), the angular distance covered also part of the equation! The further it rotate away from the centre the higher the Torque output.
I hope you don't work for an engine component manufacturer because you obviously have no idea what you are talking about. A car that makes 500hp at 10k rpm will accelerate at the same speed as the same car making 500hp at 5k rpm. The torque output of an engine is MOMENTARY as it is caused by each explosion in the engine and is not the "force" that pushes you back in the seat. That is done by the acceleration of the car (which would be the same in both cases). "So you see 500 hp @ 5,000 rpm is twice as much power than 500hp @ 10,000 rpm!" > No, it isn't. It's the same amount of power, because that is what horsepower is a measure of. It is the work done over a certain amount of time. In the case of a car, the work is moving the mass of the car. Disregarding air resistance which increases exponentially with vehicle speed, twice as much hp will be able to move the same mass in half the time or twice the mass in the same amount of time. The only part of your comment that I agree with is that the area under the power curve is more important than the peak figure, when discussing road car performance.
Thank you for the video sir. I couldn't help but notice at 1:31 your con rods big end has an even split. Almost looks like a shatter/teeth type of cut? How are you guys getting this done and is it beneficial over a conventional straight cut big end. I have never seen that.
How do you determine your total intake length to start with? I see on high rpm engines, they are kept short. Can you explain a little. And for what i can see, the intake ports are very smooth finished. There is a lot of talk about the port finish on the intake side. Thank you
Twisted Needles It’s a turd but a decent industrial engine, I see gm 3.0 4 cylinders often. I believe in the marine world they are more common. From the little I know it’s based on the old 292 inline 6. I’ve never seen one with anything bigger than a 30kw gen on em. In the air cooled vw world I think the aftermarket goes to about a 3.5.
How the hell did they get away with a rod/stroke ratio like that at 10,000 RPM without the engine eating itself? Makes me wonder what Nissan's 2007 + QR25DE would do....its cranked at 89x100mm......Hmmmm
FujiR500 Rod ratio is a virtual non issue for drag racing. In fact, after choosing the compression desired, the piston shape to achieve that, ring heights (which will dictate the compression height of piston) lastly the rod is chosen. The length being whatever it is. On an endurance application--sure piston speed is important--but for drag racing it has virtually no effect on power nor durability. Rod ratio in the low 1.40s are not uncommon. Remember ring seal is everything in a NA engine so how many laps between freshenings? Maybe 25? So rod length isnt a factor.
I see. So the risk is worth it because of the application. Short runs at full throttle for short periods of time actually don't lower the risk of the engine destroying itself, but because the runs are usually over in a matter of seconds, that can be...."not ignored" but sort of a non factor. How much torque does this engine produce? The video didn't mention that....This is amazing!
Exactly. You need the rpm to make hp. So the short rod (compared to stroke) while not preferred is acceptable. Usually the limit for an NA motor like this is low to mid 90s lb-ft/liter of displacement.
Well for a naturally aspirated 4 cylinder engine, the displacement is needed to produce that kind of power as well as high revs. Since it does not have but 4 pistons, the high revs is needed to move large CFMs. But the volumetric efficiency of high powered fours like Honda's F20c/F22c and K24 engines is much higher than most U.S. Domestic large displacement V-8s!! You'll gain more power from increasing the stroke of an engine than by bore alone because the stroke is what determines the amount/length or time of force that will be transferred to the crankshaft. It doesn't make sense when you think of this engine "just as a high revving engine" but for drag racing, the engine serves the purpose well because the high RPM moments are relatively short lived....only for about 30 seconds to a minute.

The length being whatever it is. On an endurance application--sure piston speed is important--but for drag racing it has virtually no effect on power nor durability. Rod ratio in the low 1.40s are not uncommon. Remember ring seal is everything in a NA engine so how many laps between freshenings? Maybe 25? So rod length isnt a factor.
I see. So the risk is worth it because of the application. Short runs at full throttle for short periods of time actually don't lower the risk of the engine destroying itself, but because the runs are usually over in a matter of seconds, that can be...."not ignored" but sort of a non factor. How much torque does this engine produce? The video didn't mention that....This is amazing!
Exactly. You need the rpm to make hp. So the short rod (compared to stroke) while not preferred is acceptable. Usually the limit for an NA motor like this is low to mid 90s lb-ft/liter of displacement.
it doesn't make sense because they stroked the motor and it rev to 10k. The pistons are aluminum too.
Well for a naturally aspirated 4 cylinder engine, the displacement is needed to produce that kind of power as well as high revs. Since it does not have but 4 pistons, the high revs is needed to move large CFMs. But the volumetric efficiency of high powered fours like Honda's F20c/F22c and K24 engines is much higher than most U.S. Domestic large displacement V-8s!! You'll gain more power from increasing the stroke of an engine than by bore alone because the stroke is what determines the amount/length or time of force that will be transferred to the crankshaft. It doesn't make sense when you think of this engine "just as a high revving engine" but for drag racing, the engine serves the purpose well because the high RPM moments are relatively short lived....only for about 30 seconds to a minute.
I may have jizzed my pants.
you should try top feed/stand off/shower type injectiors, they should make more power
but does it pass smog
91 octane is available almost everywhere in the US.
Macbang Where the hell do you find 85 octane??! The lowest I have ever seen is 87...
yeah i have seen 85 where i'm at and i live on a mountain
Gotcha lol
He said the engine was for drag racing.
No mention of how long you can run the aluminum rods before needing replacement.
I'm going to say what everyone else would say. I NEEDED ONE TAKE MY MONEY! lol he'll yeah K24 straight motor aspirated!
i would love to see the dyno graph!
What’s the average cost to build something like this?? I just want to know ahead of time before I get invested.
One of these in a caterham or louts 7 😍
How long until someone makes a v8 out of two of these?
JUN Auto did it with Hayabusa engines and shoe-horned it into a GT86, so who knows 🤷♂️
2:26 I literally started clapping...
So essentially there's nothing left of the K series. This isn't a 500hp K24. This is a custom built engine.
I am The Hammer I mean, yeah, I guess the block is stock?
This prolly cost around 200k dinars for development alone
