@@tayvonrose2528 but if it is going to be flatplane, then the firing order will change, and it'll need custom cams, not the ones that already exist for the k series

Because there's many engineering challenges that come with turning a L4 engine into a V8 as you might imagine. So it takes an engineer, with the proper connections and motivation to look at it and say "this is doable". No aftermarket company would spend thousands of dollars on manufacturing an engine they don't know how to make or might be a gamble to sell afterwards. Honda won't make it because Honda doesn't make V8s for the consumer, they've drawn the line on V6s and those will probably go out of the market soon enough as emissions become stricter and electrification becomes more apparent. Bottom line, this guy had all the resources and knowledge to start it, now that he has confidence in it, he can go all in and double down, specially when you have a severe health condition, having a project to keep your mind off things can help you cope with your condition a lot easier. So basically all things aligned for this guy and now we might just get to see a V8 K series. 🤷🏽♂️
Swear me and buddy always joked around about putting two k24 together making it 4.8l and it really could happen so awesome i could only imagine how it will sound
ill just say one of the last race engines my dad built we used the honda rods in a old chevy v8 because of the size/strength of the rods, won the championship at the race track.
Is the K series really that good? I know it’s good, but the GT350 Vodoo already exists and can make that power and revs with the right parts. More power to this dude, I hope he’s successful.
Yeah, the K series is arguably the best 4 cylinder engine ever made. You could argue that the 3S-GE BEAMS and the SR20VET approached it, but the K series is truly a monster.
@@LoudGuitar14 I know it’s good, there’s all kinds of dudes with $10k into a setup making well over 1000hp on nearly a stock block and crank. Don’t get me wrong, I want this to happen and be successful. I just don’t see the viability with all the relatively inexpensive 1000hp K setups.
Last week I designed this in my head, I thought that I would have to make mirror image right side head to solve this problem..so really the design is using Honda layout, but with many unique parts to accommodate being V8...
Having the exhaust exit the top is going to limit the engine to FF, MR and RR cars unless you just dump the exhaust straight out the hood, otherwise you're going to have to place the engine so far forward that a typical FR car would become front biased OR you'd have to run the exhaust in front of the engine and wind up heating the intakes/cylinder heads and potentially risk vaporlock/overheating issues not to mention power loss from heating the intake air. Also by placing the exhaust up high like that is going to make this engine top heavy , that coupled with individual intake/throttle's is going to put a LOT of rotational stress on the cylinder heads. Craig would be better off redesigning/relocating the timing tensioners and going with a more traditional valley intake. I'm no expert though and I'm just going off the limited/basic knowledge I have of thermodynamics and physics.
How was the bore spacing issue dealt with? I mean, a V8 is going to have wider bore spacing than an I4 due to the need to accommodate an extra rod on each crank throw. Were the mains and rods themselves made narrower to accommodate the tight bore spacing necessary from using I4 heads?
Narrower rods and redesigned crank journals give enough room to keep bearing spacing in place. I'm guessing here. Seems the only answer with keeping bore spacing the same.
@ Martha Mryglod There are a couple of other ways this could be handled. One would be a master rod setup similar to a radial engine. Interestingly, someone used this very setup when doing a similar project to this one - a V12 based on a Kawasaki KZ1300 inline six. An advantage here is that you could possibly use a stock crank without compromising strength so much. The other possibility would be a ‘fork and blade’ rod setup like a Harley V-twin. This setup would probably be cheaper than a master rod setup and have the advantage that both rods would still be the same length (unlike a master rod). However, it would be advantageous to make a crank with wider journals to increase strength. Both the master rod and ‘fork and blade’ setup would have the advantage of reducing bore spacing, which would enable the use of stock K-series heads. And with both setups, cylinders in each bank would be directly across from one another rather than staggered (like a traditional V8). This reduces engine length by a small amount, which could help with fitment in tight engine bays. But for a 10000+RPM motor, the ‘fork and blade’ setup would probably be better due to lighter weight and consistent rod length.
There are various v8 engines based on motorcycle cylinder heads, having a cam drive at each end of the engine. The most-produced of these is the Hartley v8, based on the Suzuki Hayabusa 1300cc engine. There are others, such as Synergy in New Zealand, who make V8s based on the Hayabusa, Kawasaki 1200, and also the BMW S1000RR. That's a fierce 2 litre race engine giving over 400 bhp
hmmmm smart idea to turn the one head around , you probably could put in a shaft in the place the camshaft would be on a old v8 and use that to make a take off from the front drive and have the reardrive above the clutch and bellhousing , think you should try to find a stock crank with the right cilinder spacing and stroke that could be adapted for youre engine block
Hot V twin turbo setup or have the intake up top and side 4:2 headers that run into twin scroll turbos, dry sump, V-Tech cams, flat plane crank, k24 stroke/bore best for turbo’d applications, lightweight flywheel
Honestly would love to see a fc based v8 but at the end of the day I would love a barra based v12 or even a vr5 based w10 but this also brings up the question how much harder is it to convert an online 4 to a v8 compared to converting to a flat 4
Should interview the Hartley V8 guy too! I believe he sold his endeavor to radical sports cars. I'd love to hear about his journey from conception to business sale!
He should also offer it as a sort of "complete" short block that way if someone wanted to they could build their own version using whatever heads/cams they preferred. As well as a full turn-key motor. I'd love to buy one but I'd imagine they'll be a bit pricey lol.
I just wanna hear it, i cannot wait to hear it for the first time 😍 this is my process as a honda boy, if i ever become a multi millionaire ill make this happen 😁
Yesss. Legend how can you not think turning one of the best 4cylinder engines if not the best into a v8 a bad idea.... Would love to see him succeed. Imagine the insane sound of it hitting v-tec ,mental.... Cheers from.a.tragic b16 Aussie
I was like; Why not just have the heads the same way and have an intake and exhaust valley and then a one side intake and one side exhaust? before then I was like; is he spinning that head backwards? then I was like he must be; Then........ I saw a gear that reversed the rotation and instantly remembered I'm not an engineer! What a dream project, I've seen some bike engined versions but the fact you want to take this to cast has me sitting upright indeed. I'm so behind you bud I'll help if I can if not I wish you all the best and maybe I'll be a customer, fek, I'll be a customer it looks awesome..👍👌👍
A V8 engine similar to this has already been done with the hyabusa cylinder heads by a British company it's been in the competition scene of sprint and hillclimbs for 15-20yrs or so and it's been very successful
But what’s make this different is he’s trying to use the same heads for both sides so it would cheaper since there’s already a huge aftermarket scene for the k series
You never mentioned what is your plan to mount this into. What trans are you going to mount to it? I would consider the T56. It would be easier to have RWD. You also didn't mention cooling plans. Which water pump? O'ring the block? More detail. It sounds like a great idea. I hope it comes together for you.
An elegant albeit complex solution would be to freevalve the engine (eliminating timing belts.). Wesley Kagan recently did a freevalve conversion of a Miata engine and made the specs available.

Custom Street Rod Build - Garage Scene
Pete Aardema
From the March, 2008 issue of Street Rodder
By Eric Geisert
.....................
Not afraid to try something new, pete will pull from any parts bin to make what he wants work. Porsche four-valve heads on a big-block chevy? No problem. A pair of subaru heads (with twin cams) bolted to a 200-cid model a motor? Already got one. How 'bout a simple overhead cam conversion for a small-block chevy? He's made more than 50 of them. And he's finally started to adapt the ford big-block fes with one of his single overhead valve kits, too.
By accident, we discovered that the bore center on a 928 is within .030” of a BB Chevy and with help from Arias, an all aluminum 4-valve double OHC was born. The Dyno results at Westech in Mira Loma were better than expected. The engine made an astounding 550 ft. lbs. of torque at 2500 rpm.
I was reading the latest issue of Hot Rod magazine and it mentioned how he got the 928 heads on a BBC block. He ordered the aftermarket block without all the machining done (no head bolt holes) and then drilled & tapped the block to match the head bolt pattern of the Porsche heads. I guess there was also a slight offset boring of the cylinders to better position things.

Yeah, the K series is arguably the best 4 cylinder engine ever made. You could argue that the 3S-GE BEAMS and the SR20VET approached it, but the K series is truly a monster.
Honda k heads
The K series is a really good design. There is a guy that took this head design and adapted it to the Nissan L series 6 cylinder
@@LoudGuitar14 I know it’s good, there’s all kinds of dudes with $10k into a setup making well over 1000hp on nearly a stock block and crank. Don’t get me wrong, I want this to happen and be successful. I just don’t see the viability with all the relatively inexpensive 1000hp K setups.
This is the most American thing I've heard and I love it
I wish the music wasnt fighting his voice at times
I wonder if this would fit in the accord or 10th gen si
Last week I designed this in my head, I thought that I would have to make mirror image right side head to solve this problem..so really the design is using Honda layout, but with many unique parts to accommodate being V8...
Love the inboard exhaust choice explanation
The Hemi Honda sounds super cool. Could become a top seller aside from the trouble's
YAAAAAAAAASSSSSSSSSSSSSSS!!!!! K48 LETS GOOOOOOOOOOO!!!!!!
10,000 RPM 🤯
Finally I found somebody making a v8 from Honda k
I always thought about an inline 6 k20. It could be anywhere from k30 to k36
There’s a company that makes a k24 style head for the old Datsun engines , look it up! It’s awesome.
@@AnDrEw122100 that sounds badass
THE 2KZ!! THE MYTH... THE LEGEND!
Seems like the project was scrapped 😔
No tf it wasn't go on the website
I want a K48 Flatplane V8 powered Honda Accord that sounds like a Ferrari with VTEC.
basically a corvette c8 zo6/c8r 5.5 v8. this guy better hope GM doesn’t offer a crate engine
But this one got V-tec
@@chomin3025 yes GM engines have vtec correct
@@michaelgomez4994 I was reffering to the k48 but ok...
@@chomin3025 k48??? the c8 z06 engine hasn’t been named. but it does have valve timing
@@chomin3025 unless your saying a corvette race car engine doesn’t have valve timing
4 I-vtec cam rockin this v8 I can’t imagine how it will sound
Having the exhaust exit the top is going to limit the engine to FF, MR and RR cars unless you just dump the exhaust straight out the hood, otherwise you're going to have to place the engine so far forward that a typical FR car would become front biased OR you'd have to run the exhaust in front of the engine and wind up heating the intakes/cylinder heads and potentially risk vaporlock/overheating issues not to mention power loss from heating the intake air.
Also by placing the exhaust up high like that is going to make this engine top heavy , that coupled with individual intake/throttle's is going to put a LOT of rotational stress on the cylinder heads. Craig would be better off redesigning/relocating the timing tensioners and going with a more traditional valley intake.
I'm no expert though and I'm just going off the limited/basic knowledge I have of thermodynamics and physics.
Did you know Mercedes, BMW, Aston Martin and many others already have a Hot Vee setup?
Use a jackshaft to run the "rear-geared" head. That way the flywheel area is clear of gears.
For some reason I feel like this needs to be in a classic mustang with twin turbos to piss poeple off
Then drift against DK in Tokyo so that you don't have to leave town.
@@SaltySRT lol
How was the bore spacing issue dealt with? I mean, a V8 is going to have wider bore spacing than an I4 due to the need to accommodate an extra rod on each crank throw. Were the mains and rods themselves made narrower to accommodate the tight bore spacing necessary from using I4 heads?
Narrower rods and redesigned crank journals give enough room to keep bearing spacing in place. I'm guessing here. Seems the only answer with keeping bore spacing the same.
@ Martha Mryglod There are a couple of other ways this could be handled. One would be a master rod setup similar to a radial engine. Interestingly, someone used this very setup when doing a similar project to this one - a V12 based on a Kawasaki KZ1300 inline six. An advantage here is that you could possibly use a stock crank without compromising strength so much.
The other possibility would be a ‘fork and blade’ rod setup like a Harley V-twin. This setup would probably be cheaper than a master rod setup and have the advantage that both rods would still be the same length (unlike a master rod). However, it would be advantageous to make a crank with wider journals to increase strength.
Both the master rod and ‘fork and blade’ setup would have the advantage of reducing bore spacing, which would enable the use of stock K-series heads. And with both setups, cylinders in each bank would be directly across from one another rather than staggered (like a traditional V8). This reduces engine length by a small amount, which could help with fitment in tight engine bays. But for a 10000+RPM motor, the ‘fork and blade’ setup would probably be better due to lighter weight and consistent rod length.
@@matthewstorm5188 I hadn't thought about most of these solutions. Thanks for the reply!
Yeah please hand me the autoCAD files for this...so I can mass produce it thank you 🔑🏆
You gotta pay for it
I knew the V6 boys really wanted a V8.
It never happened
Wrong. Craig's still working on the project.
Years ago I actually had a very similar thought process but with 2 H22A heads and it would be called the H44.
There are various v8 engines based on motorcycle cylinder heads, having a cam drive at each end of the engine. The most-produced of these is the Hartley v8, based on the Suzuki Hayabusa 1300cc engine. There are others, such as Synergy in New Zealand, who make V8s based on the Hayabusa, Kawasaki 1200, and also the BMW S1000RR. That's a fierce 2 litre race engine giving over 400 bhp
And the Yamaha version
I want to see one based on the Austin A-Series, with a cross plane crank.
I CANT WAIT FOR THIS !!!!!!!!
Can't wait to see this in an nsx
Using the superior head flow of the K series with the capacity of the V8. Nice
hmmmm smart idea to turn the one head around , you probably could put in a shaft in the place the camshaft would be on a old v8 and use that to make a take off from the front drive and have the reardrive above the clutch and bellhousing , think you should try to find a stock crank with the right cilinder spacing and stroke that could be adapted for youre engine block
Hot V twin turbo setup or have the intake up top and side 4:2 headers that run into twin scroll turbos, dry sump, V-Tech cams, flat plane crank, k24 stroke/bore best for turbo’d applications, lightweight flywheel
An affordable and reliable flatplane V8. The best engine swap you can think of. I already want to see a Ferrari-sounding RX8.
Honestly would love to see a fc based v8 but at the end of the day I would love a barra based v12 or even a vr5 based w10 but this also brings up the question how much harder is it to convert an online 4 to a v8 compared to converting to a flat 4
Should interview the Hartley V8 guy too! I believe he sold his endeavor to radical sports cars. I'd love to hear about his journey from conception to business sale!
The perfect engine for my 2019 CR-V
He should also offer it as a sort of "complete" short block that way if someone wanted to they could build their own version using whatever heads/cams they preferred. As well as a full turn-key motor. I'd love to buy one but I'd imagine they'll be a bit pricey lol.
Repco did quiet well w/ buick- olds 215 ci. V8s in this reversed induction set up. Whatta do a flat head V8 to kill overheating problem. Same app.
I just wanna hear it, i cannot wait to hear it for the first time 😍 this is my process as a honda boy, if i ever become a multi millionaire ill make this happen 😁
Did he said that he is going to include a prestroke to the engine?
Absolutely revaluationary.
Hybusa based V8 by Radical Racing with a 10.5k redline and flat plane crank = 500hp heaven.
Yeah and thats only a 2.7 litre
Hartley has been doing this with two Hayabusa engines for years.
Yesss.
Legend how can you not think turning one of the best 4cylinder engines if not the best into a v8 a bad idea....
Would love to see him succeed.
Imagine the insane sound of it hitting v-tec ,mental....
Cheers from.a.tragic b16 Aussie
I was like;
Why not just have the heads the same way and have an intake and exhaust valley and then a one side intake and one side exhaust? before then I was like;
is he spinning that head backwards?
then I was like he must be;
Then........
I saw a gear that reversed the rotation and instantly remembered I'm not an engineer!
What a dream project, I've seen some bike engined versions but the fact you want to take this to cast has me sitting upright indeed. I'm so behind you bud I'll help if I can if not I wish you all the best and maybe I'll be a customer, fek, I'll be a customer it looks awesome..👍👌👍
A V8 engine similar to this has already been done with the hyabusa cylinder heads by a British company it's been in the competition scene of sprint and hillclimbs for 15-20yrs or so and it's been very successful
But what’s make this different is he’s trying to use the same heads for both sides so it would cheaper since there’s already a huge aftermarket scene for the k series
@@abes3925 still a billit block and lot's of custom designed and built stuff it's nothing different
You never mentioned what is your plan to mount this into. What trans are you going to mount to it? I would consider the T56. It would be easier to have RWD. You also didn't mention cooling plans. Which water pump? O'ring the block? More detail. It sounds like a great idea. I hope it comes together for you.
An elegant albeit complex solution would be to freevalve the engine (eliminating timing belts.). Wesley Kagan recently did a freevalve conversion of a Miata engine and made the specs available.
I remember first seeing 2.75L K builds making around 400hp all motor
This is going to be dope
i dabbled in something like this it's a cool design! i also considered a flat 8 with one of these
