My 94 s10 been sitting in the barn since 2023 waiting on this unit
For anyone that is seriously considering this and doesnt want to wait. Look into the Mercruiser 470, its an aluminum block 3.7l 4 banger that runs a ford 460 head.
I’ve been interested in this thing for years!
DO NOT look at the 470 mercruiser. It is easily the WORST marine engine ever. Galvanic corrosion, head gaskets, overheating, exhaust manifolds, and on and on.
@@nunyabusiness2294 So a perfect Hot Rod motor?
@@nunyabusiness2294 yeah I wasn’t interested for a marine application, more like for a Miata or Rx8.
@nunyabusiness2294 Most of those issues are directly related to marine applications.
1987 S10 long bed...... that's what I would put it in ....
I have a 1998 S-10 , perfect home for this engine!!
hell yeah!
I mean basically anything but a like 3/4 ton truck and even then with a turbo you could it just wouldn't be ideal
Why? Put a used full ls in for way less money then half a new one.
I want it asap for hummer H3
Inline 6 LS would go crazy
4200?
I was just thinking that! Somebody made that v12 one, why not? At least the heads can be slapped on a ford 300
@@CannontimeNot an LS based engine.
@@ItsDaJax I know, buts it’s a modern inline 6 from GM. Wish it had the aftermarket support the LS does
@@Cannontime It's getting there, they've gotten more popular in just the last couple of years. Only problem is it's a really tall motor, like 8 inches taller than an LS. If I had all the money I would put a big turbo built 4200 in my Corvette.
This would be a great Fiero swap engine and would lovecto get my hands on one
A pushrod ohv and not an ohc which is nice
I'd absolutely do that for a fiero! I've also thought k24 and honda 6spd lsd
The 3.6 engine block has been in use for years. It's the Orion industrial engine. It currently uses a Ford 351 Windsor head.
This engine in a Chevette would be BRUTAL
I'd like to find a mint Chevette to drop in a 3.9 V6-60* I have that came out of an Impala. Still looking...
I haven’t seen a chevette on the road in 20 years.
I saw a chevette with a 500" Cadillac V-8 in it. Fuck all that 4 or 6 cylinder non-sense
@@davelowets In the mid 80's, while cruising "the strip" in a small midwestern city, two young women pulled alongside my buddy's '74 Camaro in a Pinto with a dual-quad tunnel ram 429 and wheelie bars. We were flabbergasted.
Not everything has to be over-the-top. Some cars just need to double the horsepower, not put a 550 lb. big block over the front axle.
If the block was Aluminum i could see ppl in the light sport an experimental avation world being highly interested in the turbo version with so much power at low rpm. Kinda depends on what the primary and secondary imbalance vibrations are like tho, from what i understand.
Right off the bat, it lacks any track record that could lead to FAA certification. Then the orientation isn't conducive to fitting in the nacelles of existing aircraft. The turbo and cooling system add a lot of complexity, and the power output isn't that good considering all the downsides. Sounds like it's all liabilities with no benefit other than "it's a LS..."
@StringerNews1 I'm just beginning to learn about aviation engines. I don't know anything about the requirements the faa would require, just noticed that in small platforms people seem have been able to use automotive engines and snowmobile engines if they were small and light enough to fit the platform. Obviously I have much more to learn about such things, thanks for the correction.
@@twotrackjack2260 hey, I'm just discussing too. I can't claim to be any more knowledgeable about the subject. I'm just a frustrated would-be pilot who never found the time _and_ money to finish flight training, so I studied the _topic_ of aviation at the local library. Somewhere along the line, I came across a discussion about why most GA engines resemble old Porsche power plants. One thing I learned from that was that flat engines worked for that purpose in part because the plane could have an optimal prop size and height without a gearbox, and the pilot could see the runway ahead. It also talked about how simplicity reduces failure rates; you never want a forced landing in any plane! I'm just repeating what I read years ago.
@@StringerNews1 Ahh I got ya. Yea, everything I've learned thus far has hilighted the benefits of using a boxer style engine. However, that doesn't mean they're the only way to go. My only non commercial flight was in a home built kit plane in the late 90's, it was powered by inline 4 cylinder volvo car engine. Can't remember if it was turbo or not, but I was really surprised by the fact he could use an automotive engine.
@@twotrackjack2260 sure, you can build an experimental aircraft and bypass most of the regulations that have allowed the flat 6 to rise to the top. ROTAX was founded way back in 1920, but it was a major investment by owner Bombardier that got the company into aircraft engines for the first time. And of course there was Porsche's contribution to Continental & Lycoming that pushed that design to the front in the '50s.
When I was a kid, we used to fly from Chicago to Amarillo to see relatives. The flight would stop in Wichita, where all these guys with white shirts and skinny ties would pick up their oscilloscopes and IBM disk packs and get off. Back then, Wichita was a hub of GA aircraft design. The industry wanted everyone to own a plane. I wish we could return to that time of great expectations! And yes, having more engine manufacturers investing would be very good indeed.
When I saw this motor for the first time and read the stats. It's an LS motor. 3.6 l. I simply applied the same calculation. I applied to all all motors. I figured out how much air you could move through the thing because that determines the horsepower motors are just air pumps
3.6* 61* 8,000/3456 If you can make a full size LS spin to 8000 RPMs you can definitely make a half size LS do it too
At those specifications that I just gave you which is cubic inches* RPMs and then divide by the standard, this motor moves 508 cubic feet of air per minute.
A standard hot rod motor has to move about 1.35 CFM to make a horsepower. An IndyCar motor is closer to 1.0 CFM to make a horsepower. If you go to things like the old old 1988 trans Am, it's more like 2.8 CFM to make a horsepower
But modern-day hot rod motors, if you sit there and do the math on every Dyno run you see average about 1.35 CFM and then if they have compression Ant a high lift cam you can get it closer to 1.28
So this motor with the proper cam and RPM is perfectly capable of making that 340 horsepower naturally aspirated don't even need the turbo
But a good turbo on this thing and it would be a monster
Also, I am very well aware that CFM per horsepower is usually not a reference point that people use. It was simply the metric that I started with years ago watching dynamometer runs and calculating out how much air they were moving to acquire that power
Not sure about the 8k RPM because it's a very long stroke from what I understand. From what I understand it's based on an engine used in airport tugs and stuff like that. I'm very interested in what they will come up with.
Balance issues would prevent the engine from ever reaching anything close to 8k rpm. There's a reason why 4 cylinder engines rarely exceed 2 liters of displacement by any significant amount.
Torque per liter is my question. 500 lb/ft at 1800 rpm?
This motor won't get near 8,000rpm. It'd be surprised if it revved over 5500. 4 cylinder is a totally different engine than a V8. This is an industrial motor (for generators and heavy equipment), the muscle car world just went nuts because of the LS head on it.
@@383mazdaMotorcycle engines and the k24 of the S2K, and the toyota engines in Lotus cars rev over 5500.
Appreciate you digging for answers. The only way this happens is if someone else does it.
Would love to put this in my Fiero, 'modern' SD4 build
@@asylumville8544 time will tell I guess. But it would be cool in a small car like a fiero
Ha, I was thinking the same thing, my Fiero GT has been sitting for years now could use a new engine among other things.
Replacement for The hurricane 4 In my 1958 Willys CJ3B

Great offroad option
There’s a entire market out there for industrial applications…
This would be awesome for so many applications.
Got an '87 S-10 "Zimmer" that needs the 2.8L V6 swapped out. I can totally see a turbo 4-banger in there.
1972 Vega GT with shortened 12 bolt.
I put a SBC in a friends Vega Wagon in a weekend, shortened driveshaft and all.
Blueprints sister company origin sells this for industrial use already it's lower horsepower though
And why the power output is at such a low RPM
Block is different too, bell housing is proprietary.
I would love to have one of these in my 89 jeep YJ. Currently a 2.5 L four-cylinder. So the four-cylinder swap makes sense to me. More HP please!
When your video came out a couple of years ago, I actually called blueprint engines and they said that it was still a concept and on the back burners, but I had my fingers crossed.
If this engine is actually produced I would love to put a turbo version in a conquest tsi as a sleeper
That really is a nice looking Duke. The torque numbers are hard to believe.
That's because it's a turbo motor. With turbo lag. Not the instant acceleration you'd get from a big block.
@@StringerNews1 with a modern turbo it's probably pushing those numbers at 15 to 2100 RPM. With the right gearing that's not really much of a delay.
@@custommotor unfortunately linguistics (saying "modern") doesn't magically invalidate the laws of nature that have always existed. 15 RPM isn't gonna happen with a motor that size. Likewise, you can tune an engine to be strong at a given RPM, but it comes from somewhere. A big turbo will take forever to spool up because of inertia, and a small one will run out of CFM before the head does. The only "modern" addition to that formula is using electric motors to spin up the turbo, making it a hybrid. But then, you might as well use the hybrid system to power the car directly.
@@StringerNews1I don't think this is meant to replace what big blocks do. Besides a somewhat laggy small displacement engine with a turbo is a very fun Jekyll and Hyde feeling vehicle. I have driven a 400whp K series and if you watched your shift points it drove like a stock Honda. Rev it out a little and it became a monster.
@@StringerNews1 he obviously meant 1500rpm not 15
I am still wanting / waiting for this engine ! Lets go.
Man this would be a bread and butter engine if people had a finished product. This is perfect for jeeps Camaros S10 even some JDM.
BLUE PRINT WE WANT THIS ENGINE!!! THANK YOU
500ft.lbs. at 1800?!?! That's what most large generators turn. That thing would be a beast in a home generator.
it is based on a generator motor.
Definitely looking forward to them releasing this engine as it will allow my project to be possible to race in IFO (import face off), PFI events, or the king of drag racing events WCF (World Cup Finals)
K series is a great engine and ahead of the field in the 4 cylinder world. However, per certain class rules I can’t run an import engine in a domestic (compact size) car. So, this blueprint engine will allow me to run in these classes as I’ll have a domestic 4 cylinder engine in a domestic compact size car
This 4 cylinder would be perfect installed in my 1980 international scout terra (392 4 speed current) with 4l60 overdrive transmission. The 392 smokes bad and by itself the 392 outweighs a sbc 700r4 combination. Lol. Thats crazy heavy. I've been thinking of possibly swapping my terra to independent front suspension and making it a 2wd roadster with a big block chevy auto overdrive or tremec 6 speed. I'd probably just build a chassis to swap the body onto that way I could always swap it back to a 4x4 scout terra top to bottom. Just something I'm kicking around thanks for the great content. Keep em coming
I’d drop it in my 6-speed Honda Fit if possible. 😎
@@MadMexism nice
Let's be honest, with the way the laws around cars are changing, if it's not out by the middle of 2025, it's never getting made. It's only unique parts would be Block, inlet manifold and Crank, so would be super easy to get other parts for.
As for what to put it in, a Holden Torana would be ideal, same with a early '80's RWD Corolla, Holden Gemini, '70's Ford Capri, every light duty pickup ever, Baja trucks and buggies, hillclimb cars, and if the block is Aluminium, small aircraft and boats - it'd be absolutely wicked powerful in the 3/4 sized carbon fibre P51 Mustang from Titan Aircraft.
If I was an off roader easily put it what ever Jeep or other 4x4 I had . Relatively light, twist like a big block even at 10,000 feet, 1/2 the fuel or better, simple to work on… plenty of room to fit it in. Yeah would probably like it at a less shaky 2.5 liters and settle for 350 ft lbs of torque and 225 HP but a 5k redline. I think there’s plenty of potential even in 2.5 l. Doesn’t the new Acadia run pretty close to that displacement and the 4 cyl Bronco is like a 2.3.. I think both of those with turbos are around 275 300 hp and again if you look at engines from the 80’s 1 ton trucks were running big blocks with similar numbers and pulling 10k lbs trailers so plenty of juice for a 4x4 😀. A 2.5 with a 6500 redline might be an awesome rally or autocross engine especially in an aluminum block!
Dude, these guys have to make this engine. I would put it in my Chevy Equinox! 👍 👍
Less electronics than a K series? How so? Doesn't it still need all the same sensors any other fuel injected turbo 4 cylinder is gonna need?
I mean yeah a K series is gonna have a lot of emissions stuff, but if you're building one for a performance application you're not going to use any of that.
It's going to have a standalone ECU with all the same sensors this 4 cylinder LS would need.
Hmm..I guess you do bring up a good point 🤔
A k series is nothing short of a high performance engine but still a small 4cylinder like a ferrari v8 cut in half. An ls cut in half is more like a forklift engine lol it almost doesnt make sense at all but im curious anyways. Also the eletronics in a k series are simple and always work plus its why they have such advanced timing capabilities
All you would need is crank trigger wheel and sensor for a C.O.P. ignition box. Set of webers carbs and be good to go.
I thought the same when I heard him make that claim.
This would be an awesome compact car derby engine, less wires, msd ignition, carbed and on methanol... Jesus it would be a beast!!!
Man this would be perfect in my 1989 Volvo 740 wagon. It’s in the spirit but with more displacement.
It would be almost moronic to compare this motor to a Honda k series. Not even close to the same animal. This is a hugely powered low rpm tractor motor. This is diesel numbers in a gas motor. This is the coolest swap for smaller utility trucks and SUVs without the 4bt weight. I want this for my Jeep
Honestly, I think there’s even a market for the guy that just wants an old car that’s a cruiser. Wants to be able to take their vintage car or truck out reliably, and not burn a lot of money on fuel if they don’t want to. There’s a ton of options out there for big power. There’s nothing with this concept in mind, unless you’re talking an old straight six and they’re getting harder to find parts for let lone find at all anymore.
Be a very cool marine turbo power plant
I hope this makes it to local oval track racing
Hopefully after all the r&d costs it's still remains cheaper than their V8 options or else it seems kind of irrelevant. A compact naturally aspirated version is the only thing that makes sense to me since if you're looking for additional power and needing extra space for a turbo and intercooler, you may as well just get one of their V8 options that already exist.
At the end of the day, if it's actually based on an LS4, all I really want is that custom engine block and crankshaft (and maybe oil pan) then I can just put off the shelf LS4 parts in it (conrods, pistons, cylinder head, cam, etc) and build it out however I want.
Aside from my Fiero GT needing a new engine, I think building a S-10, Colorado, Blazer or Tahoe with one set up as a generator to power a small battery back and 2-4 motors would be cool, with the ability to feed power to a house or w/e for emergencies and what not.
the main problem of this high displayment 4 banger is that the vibrations are crasy, they will destoy the engine if they are not balance correctly and for this reason i thinks it is a low priority proyect. It requeires a lot of money and really good engeniering to make it realibale, beacuse you are not going to buy an engine that it going to destoy itself in the first 2000 miles.
I think it has more to do with RPM, than displacement.
I have a 2000 K2500 ex Forest Service truck with a 5.7 Vortec that guzzles gas. It spends it's days tooling around the mountains of Idaho under 30 mph. I would love something better than 12 mpg.
Early 90s s10 blazer.
I could see this possibly being used as a resto mod engine for antique gas tractors maybe. The bottom end was from an airport tractor design.
I wanna hear this lil monster
Aftermarket 22R-EFI Turbo? Yes, please.
I wonder if they do put it in to production if they'll offer it as a tall deck version. Maybe even an inline 6 cylinder variant.
In a lightweight car, a 250hp variant would do just dandy. And still be reasonable reliable.
My dad converted a 400 small block into a 4 cylinder that made over 300 hp and turn 9000 RPM. He got the plans from Smokey Yunick… That was in late 70’s
I have more fun working on a small 4 cylinder engine than a V8. It would be a nice weekend project.
Huge upgrade for the 2 door chevy tracker 2.0l, give it the herspur it always deserved with a real chevy engine to match the badge.
I would love to take and use that engine for a tube chassis mid engine sports car with a flipped Porsche transaxle. Light weight with enough HP to make it fun and affordable.
Aluminum block would be great,all the samurai guys,jeep guys and even buggy builds would have another swap option
This engine would be great for compact builds.
If it's basically a iron Duke with a ls rec port head then why hasn't anyone else just done it. The low rpm high tq they are quoting makes it ideal for many applications, mostly industrial. It needs more rpm and then the hp numbers would be more ideal for a performance application.
Tons of potential. Can’t wait to see it made available.
They should make a cross-plane crank so that it will have a V8 like sound and it may be better balanced than huge I4s without a balance shaft are. If they could go 4.125"x4.125" or 4.125"x4.25" or 4.185"x 4.125" or 4.185" x 4.25" that would be really exciting as an N/A engine 350hp or more with one of those Blue Print rec port LS heads shouldn't be a problem at all, Richard Holdner got 700hp from a 468ci stroker with a factory 823 head.
Explain the cross-plane 4-cylinder engine and how it would differ. I've never heard of it and would like to understand the concept.
"We finally have news!" ... "There is no news."
If it's viable, it's got more demand potential than the back burner can provide. Just my opinion. Thanks for the investigation and report
My pleasure 🙏
I got a pontiac sunfire i would loto drop this in. Also a pontiac fiero would be great for this
The basic engine is an industrial piece made specifically to run loaded up near the torque peak all day long. Reliability is the starting point. Will it produce more power than a Honda? Likely not, but it will probably last longer.
I want one for my 86 Tin Top Samurai.... Low end torque in a gas engine
Having did a bit of digging, the 340hp-500lbft figures are with boost at 1800 rpm. Under design by blueprint engines using an origin block.
That is correct
As soon as it's on the market ima get one for my Vega
I want to put it in a first gen ranger or first gen 4 runner because it would be so delightful to annoy the purists and would go great for lifting those and dealing with bigger tires.
I'd just love a 4 cylinder that gives lightweight and offenhauser like sound.
I guess if it had to be GM this would be very cool engine for a old solstice of sky
If that’s the same rectangle port head found on the ls3 and ly6, that motor should easily make 300hp NA at pretty reasonable RPM.
The size could definitely cause some NVH issues though at higher RPM, so maybe 250HP NA is a better estimate, just because it might shake itself apart if you spin it high enough to make 300.
Gen 4 SBC
@@Cowboy.underwaterstill a concept engine
A 3.6L inline four will shake itself to pieces at 5000rpm, even with a balance shaft. No way is it going to turn high enough to hit 300hp more than a few times.
I would do a boost caboose build on this with a 4.3 V6. Supercharger this one with a centrifugal supercharger, pipe the air from it to the 4.3 V6 with a turbo, then pipe the turbo from the 4.3 into the ls 4 cylinder and probably stick it in a PT Cruiser.
It's an interesting idea, especially for the S10 swappers, but... to be honest though, if I could stroke my 2.2 to 2.5 and do some other basic massaging and get 150hp and decent torque NA, that would be on the books first. That little thing's been giving me 120hp (or less) for the last 340,000 miles and is rarely less than "adequate", and that's all I want.
Then again I'm weird enough to occasionally think about a 3 liter (circle track) Iron Duke in a 30's roadster or a model T runabout with a G10 in it. Yes, that G10, the Geo Metro (suzuki) 1.0 3 cylinder.
Early jeep, all the old small pickup trucks, Ford model a. With that kind of power and torque it will move most anything.
I have an FD Rx7 I bought as a rolling shell. I would love to put a turbo version of this in it!
I venture to guess that the real issue is in its high cost for it's relatively low horsepower numbers. I personally have not seen any anticipated cost numbers, but its unlikely to be under 5k.
we’re living in a timeline with an ls 4cyl and a v8 k series lol
i think it’s appropriate to put the LS in a civic and the v8 K in a corvette
Making 4 identical Miata track cars for events is what I'd use this for.
Telling me I could get parts of the shelf due to it being LS and it's a smaller form factor. Hell yes
My matrix needs an engine, this would be perfect
I'd love a mopar version b/rb/or hemi based b/rb would be awesome for those of us who like old school carbureted builds, hemi for those that like new school hot rod engine building
I’d be tempted to put one of those in my 1969 Chevelle Malibu Sedan. But I’ll probably rebuild the stock 307 V8 first.
Big 4 cylinders don’t typically rev high enough to really make horsepower. It’d be good on torque, but so would a smaller engine with a blower.
For the cost and hassle might as well just do the V8 swap. Funny thing is the 4cylinder would probably be harder to fit since it’s standing straight up and would be tall.
If they make the thing relatively affordable, it'll be a circle track killer. I'll take inexpensive for a CJ-5 project right now.
they should do a pre-order many people would put money down for their projects e30s miatas, brz many many more
If there were a NA version and the output was suffecient, I'd build a generator in the 40KW range with the low RPM for many hours capability it should have and run it on propane at my farm. Yeah, I know not flashy, but I don't have a smaller truck than a 1 ton. I would assume there are great automotive applications for the turbo version.
My 2000 s10 5 speed is drooling over that with hungry eyes and cash in hand
If you have the 2.2 get rid of it and purchase a remanufactured 4.3 for half the price. My stock 4.3 has 440k miles and still running great. I will absolutely rebuild it and keep driving it on to a million miles.

If only Edlebrock actually released the cross flow jeep 4.0 head they teased years ago. That would be the aftermarket performance killer with millions of blocks out there.
@@trekkie1701e that would be awesome for sure
Nah. It'd still be a jeep engine. That's why we all end up swapping for a GM engine anyway. This 4 cyl would be the ticket for my XJ.
I'd love to design and build a mid engine sports car chassis for it, with a six speed manual.
An '09 GMC Sierra 2500 wide-side (parts truck). And I'd take the L96 out of that to build for another project. And, the L96 in it now is getting tired. So I'd love to put a small turbo on one of these giant 4 bangers and get some killer gas mileage.
Would like to see it in an LLV mail truck.
That would be awesome in my 36 Plymouth.
By the way, Smokey took a stock Iron Duke, put a small supercharger on it with a turbo, stock fuel system with a bit more pressure and the stock HEI ignition system with a bit of tweak and made 250 hp with over 350 ft pounds of torque and not a single peep of ping or knock. That was on a used, over 75k mile, Iron Duke with the stock head. Guess someone had to finally figure out how to get a better Iron Duke and they just might have done so. Kudos! Now get it out as a kit or assy and let's get on the road with it.
If it's one thing I learned from my days playing with Ford 2.3L Limas...It doesn't matter how bad the cylinder head is, so long as the bottom end is strong enough to handle boost. Never had mine on the dyno, but that car (thunderbird) would easily outrun bolt-on LS1 camaros back in the day. Probably 350-400whp @ 25psi boost.
It would make a good boat engine, good engine for a chevy Luv or S10, or a concrete pump.
If it delivered the numbers being speculated, it would be an animal in a small mid engine setup like an older MR2 or Fiero
My '87 S-10; short cab, short bed, 4cly, 4-speed, manual steering, manual brakes, non-air, all original down to the air cleaner wing nut truck would be perfect the home for the LS 4cyl. She weighs 2,470 with the iron duke/Izuzu trans combo and 3/4 tank of fuel.
I wish they’d hurry up. I mean all they’d have to do is recast the iron duke with a deck surface that matched the LS head. That should be easy for a foundry. Come On!
Shove the engine in a 1976 Buick Skylark. The origional V6 engines always blow up!
I have a Mk1 Mr2. My chassis is ready 😎
Blueprint I hope you read the comments if I remember correctly, it had an LS3 style head, but I also thought you had a hemi head version which would be fantastic because of the flow dynamics of the head. I think it would be fantastic for many reasons, jeeps rat, rods, little hot rods even full size trucks open your forethink for a turbo, charging pro, charging fuel injection and carbureted. I understand this is a back burner thing for you, but honestly, the possibilities could be endless because the Cummins 4BT Has gotten very pricey
You're overthinking the cylinder head - because inline fours have god-awful balance. You can get away with it on little L4s, but the bigger they get - the worse the balance gets. About 2.0L is on the edge without balance shaft. 2.5-3.0L is on the edge WITH balance shaft. This is why you don't see big L4s that do high RPM....as in above 4500-5000 or so. Even the 3.0L Porsche 924 engine shook like a dog pooping razor blades at 6000. Coming back to the point - if you're not gonna turn high RPM, you don't need big heads that flow great. All you can really make use of is a good, moderate head - like an LS1 or LS6 type, so long as we're talking about LS's.
Swap this into UTV’s, fit between the wheels but more reliable possibly
This would be a game changer.
In what game?
Yeah Blueprint is selling all those massive 630Ci blocks and then customers are overspinning them like crazy. Its a great market ploy. Build a decent HD engine with a bit of a flexy block and 80% of your customers will never tune it past 700HP or at least ever REALLY run it there. But that other 20% chews thru these 2 or 3 times before they give up and go for a billet or at least prepped thick sleeved. heavy studs GM performance block like tex speed or jegs, GM offerings.. It ends up you maker better more efficient power with a much smaller Coyote 4V, Ls 2 or 4v variant
