- Newcomer Racing smashes world records with the most powerful Jeep 4.0 engine ever built. This is a 4.0 block built as a stroker and filled with hard block. The block, crankshaft, cylinder head and oil pan are all OEM components. Newcomer used an On 3 turbo to provide the boost and almost everything else is custom.

People have only been talking about the power potential of the Jeep 4.0 for over 20 years. He proved it can be done even with a paltry aftermarket compared to LSland and with a crap ton of fabrication. My hat is off to him. He sells a turnkey stroker engine with 300hp for $6K.... so... If throwing 20lbs boost + methanol at it didn’t grenade it, the NA version will be solid. I will look him up to get an engine for the swap on my WJ. Way to go!!!!
WJ's unite
2 WJs and LJ🙋🏻♂️
When I wanna do a rebuild I'm doing a full swap for a stoker 4.0. 00 WJ with 195k, and a KJ with 246k
@Michael l I live in Texas my Jeep don't go over 210f, 200f is the normal running temp for the 4.0 he must of had a cooling problem of some sort. Mine normally stays around 195
Michael l there’s a few years of 4.0 that had weak head castings. They likely had cracked head not head gaskets
My uncle was one of the designers of the 4.0, when it was still AMC. He said they put one on a dyno , and ran it non stop for two years. They simulated daily driving, snow, rain, mud and towing. It ran a 55 gallon oil drum and a 55 gallon coolant drum.
I believe this. I've seen them in industrial applications where they've run for years on end outside! What a great little engine.
That's a really interesting story! That's a hell of an endurance test alright. Thanks for sharing.
OUTSTANDING...I HAVE ALWAYS LIKED THE 258...Glad to hear your Uncle was one developing this great engine...
@@MrCarnutbill67 FORDS BIG 6...2.9L IT WAS LIKE THE BEST USED 6 BANGER FOR INDUSTRIAL APPS...MANY NEVER REV PAST 3,000 RPM AND LIVE FOREVER...
@@bigsparky8888 300 cubic inch is close to 5.0L,the 2.9L your talking about is the 4cyl forklift version
I kept watching and hearing those RPM's climb - right along with the power. Then, I just kept saying to myself "This is a JEEP engine!" Put a big smile on my face. Great job Newcomer - amazing outcome!
I mean, technically it was a car engine first. But yeah, at least the head was designed for jeep.
@@Levibetz
The sad thing AMC could have done all of this to the 232 or 258 in terms of fuel injection in the late 70s. The US auto industry was very late to the party in terms of fuel injection aside from a few fuelie Vettes.
@@mpetersen6 check out the Spirit AMX turbo concept they built as a pace car! It had bosch fuel injection on a 258 with a turbo that made around 400hp. Also, what became Bosch's d-jetronic was actually based on Bendix's efi developed in the 1950s and used in chryslers and I thiiink some nash models? Super rare, and a failure in it's day until bosch perfected it and it saw wide use on VWs, saabs, and others.
@@Levibetz
I'm familiar with the Spirit pace car that was put together for IMSA events. At least I think it was IMSA. The only thing that will always hold the 4.0 or any other US built inline 6 as far as power output goes is the cylinder heads. Ford, Chevy, Chrysler and AMC all went with non cross flow heads. These engines were built as utilitarian power units. Entry level motors. If you wanted more power you got a V-8. And to be truthful most if not a lot of them of the V-8s were the US auto industry built back in hay day of the muscle car didnt put out that much power. Even the legends from that time are dogs compared to a lot of engines today in terms of hp per cubic inch. Even Pontiac's OHC six used a non-crossflow head. In fact the Vega 4 cylinder head looks a lot like the Pontiac. One reason that the manufacturers used a non-crossflow head was the intake manifold would be in the way of the distributor. Today with modern ignition systems that's not an issue. Remember these were the days when you were looking at a tune up at least once a year. The reason the intake and distributor would interfere is the dizzy is driven by a helical gear on the camshaft. On an inline you usually drive the dizzy from the center of the cam or between #1 and #2 cylinder. Plus the same gear drives the oil pump by a tang on the dizzy shaft that fits into a slot in the input shaft of the oil pump. One way to convert an inline six to OHC is to use the existing camshaft for your reduction and drive the SOHC or DOHCs from there. And it wasn't just the US manufactures that built inline sixes this way. Look at some of the European and Japanese inline sixes. Both OHV and OHC. The only OHV inline 4 or 6 cylinder engines I can think of that did have a crossflow head were the two built by Pontiac. The Trophy 4 and the Iron Puke. There might be others, and probably are, so there is no reason that others could not have.
@@mpetersen6 I would have loved to have seen a 258 or bigger straight 6 fuel injected AMC in a small 5 spd performance car and some Jeeps.
That HP dip is what typical home garage builders run up against then never figure out why that motor just doesn't feel right. Great tuning example here.
plenty of home builder do overcome development problems such as these
That dip is always a valve train instability issue. Usually correctable by using different springs. This is the reason I have EVERY one of my engine builds dynoed.
At 8.6:1 compression and the strength of the internals, I'd be happy at less than 20 pounds of boost and less than 650 hp. Lots of power that will last forever.
I'm a huge fan of the 4.0 L straight 6! I've never seen anyone express their knowledge for extracting these powerband numbers before! You guys are crazy!
More non Ls builds i love it!
Underrated comment
Lame Shit compared to this!!!
Ls engines are ugly!
The reason people go with LS is because there's plenty of parts and they're cheap. This motor was probably very expensive to build and you heard the guy, lots of parts are special made. Cool, but not practical. I'd rather pull a junkyard 5.3 for 500$ and boost it and make more power than this easily.
Non LS build but at what cost?
I've had too many jeep people tell me that 190hp on a 4.0 is its max. Of course most of them are not owners of a 4.0 i6 engine.....
Naw there are so many options to build one. My plans for mine is the poor man's 4.6 stroker. 4.2 crank, rockers, cam, pistons, and some other things. But it should make 200crank HP easy. They say if everything is solid it should make 242hp
@@geoffmetituk3604 meanwhile i get a tune and go from 200hp to 276hp. Gotta love turbos
Full bolt ons with edelbrock head and comp cam. Thatll get you somewhere
I turbo'd my Xj, best thing I ever did.
@@geoffmetituk3604 you’re gonna make way more than 200. My 05 with just an intake, exhaust and plugs makes like 200 you’ll at least be at 225 or 230
That inline 6 has been my favorite since I was a kid. My dad had one from the time I was born till I was 17. Had 280k miles and still ran like new without leaks. Not to mention the excellent torque
That is just insane to see a one sided head pump out that much power.
The 4.0L I6 is such a wonderful engine...
My dad worked at the Engine plant where these were built. He was a Tin Smith in maintenance, but he would talk to the guys in the dyne room on occasion. The 190hp stock number was where they had to dial it in to avoid damage to trans and driveline components. As you can see it's a beast.
For it's time, the 4.0 made incredible power. Almost 200 hp when most v8s only made about 250.
My auto 4.0 ho. was faster to 60 mph than a NA 5 speed Stealth. It was dead even with a mk3 NA supra to 80 mph.
What was the best true number before detuning?
@@nickthompson9697
The talk at the time was 1 hp per CID. It's to bad they never designed cross flow head for it.
Cross flow head would have kept it relevant for another half century.
@@nickthompson9697
Theres three ways to get one. Cut and weld a set of SBC or SBF heads. Design, make cating patterns, cast and machine a special. Or design and 3D print an aluminum head that needs a lot less machining. The V-8 heads are probably the cheapest but you also have the problems of coolant passages and thermostat mounting
As a WJ owner, this is making me......excited.
Hentai!
Supercool. What I dug the most was the flatness of the torque curve on the NA pull. Harmonic damper or beehive valvesprings (or both), whatever it was, it worked.
I love every type of engine, of course v8 are one of my favourites, but let me say, there´s nothing more satisfactory than see that a solid, clean and powerfull inline 6, in this case it´s a jeep one, but i could be a chevy, ford, whatever, i can´t imagine what would be a car with this engine in it, almost 900 lb-ft under 5k!! and 861hp dude, and they stopped the pull just before 5800....... boy this is a totally KILLER street engine that i would love to have.. Amazing job to the guys from Newcomer Racing, amazing job people. Hope to see this beast again making ever more power
I agree, I am curious if you could keep it running at normal operating temps in a real application though. You’d probably have to do a lot to get a good cooling system figured out. Those 4.0’s run hot and I’ve seen a lot burn through head gaskets from running so hot. It would be awesome to stick it in an XJ and make a daily driver/rock crawler that has a lot of power to tackle any trail running 40’s-48’s you’d have plenty of torque to turn em no matter what you’re doing as long as you have drive train to hold up to it.
I've always enjoyed upgrading the 258 in the CJ with cam, 4bbl intake and header set up instead of the usual V 8 swap.
Ford 300 I6, also a platform for power up grades.
Thank you for actually showing Newcomer assembling the engine instead of the typical montage other videos show.
I've got a custom turbo on a Datsun L28 which is also a reverse flow head. You have done a remarkable job of custom making components to overcome the limitations of this Jeep engine. And these videos are some of the best produced I've seen. Pure, direct, factual and educational.....all without a bunch of distracting screaming music....amazing! Thanks!
That shop is literally 30 minutes from my house!! this is amazing!!
I'm in rock hill I want to go check out both shops and maybe get a tune there!!
@@Ayyjaxx please do it!
Just looked them up and its about am hour from me, cool to know its stuff like this within driving distance

I find it funny that today while driving my 97 xj I thought of turboing my 4.0 in my jeep then I get home and this pops up lol awesome video im impressed with the numbers this pulled
I've had several examples of the internet "reading my mind."
The 4200 Atlas is starting to get some love too. Boosted I6 engines are dope.
Really nice to see the other straight sixes getting some love too Here in Brazil we are kinda used to high horsepower on the chevy 250 but seeing the jeep 4.0 getting built to hold high power congratulations to the builder for trying something new and to the guys of the channel for documenting such amazing build
Hey thanks!
Hello sudamerican neighbor, im feom Argentina and so we do
Enzo - I saw a fair amount of those when I worked in Sao Paulo, along with Falcons. Great car culture there!
I wanna see it in a Jeep now!
Jeeps aren't my thing but newcomer is amazing. I love this channel.
That was a sick video! Wondering how much it can take before it splits the block or raises the head. We should start a gofundme so we can find out
Yeah,, do a Holdener LS test,,run it till it throws a rod dyno run or spits out a bunch of things!!!!!!!!!!!??!!
That bottom end scares me. I think that'd be the first thing to go bang.
Anytime soon. This engine is only doing short bursts at max power on the dyno.
Under load for any length of time on the road and at nearly 700hp the crank/ rods will break, blow a hole in a piston or two or six
or split the block..
That straight six is bad to the core , thank you.
That's incredible for the ol six. And I would love to see a 4.9l ford under the same conditions
PowerNation is doing a 300 right now
You should look up the Ford 4.0 SOHC Intech, it's the predecessor to the "Barra" and it's insanely capable.
They sound better than the Barra
@@harleyfelts668 thanks for the heads up.
But I'm already subscribed
Yes my brother I've been a mechanic for a long long time I went to school after eat Smith high School in the Bronx and I've been doing it ever since and yes you can build the 4.9 six cylinder I had a friend that had one and he built it up to about 550 horsepower in about 496 foot-pounds of talk that is pretty good horsepower most likely more than what you need anywhere in the city but it's awesome to have it so your answer is yes I seen 4.9's built up it just takes a lot more money to build them up than the six-cylinder Cherokee it is a cheaper belt on the Cherokees 4.0 than the 4.9 you have to spend a lot more money on the 4.9 Ford belt 6 cylinder that is the big difference except if you have that kind of money extra to spend an overall I believe the 4.0 is more reliable than the 4.9 I hope this helped you my friend
Artistry comes in all forms! Thank you, I love it.
I'd love to see this on the street in a 2800-pound '68 Rambler American!
Hard to believe that a straight six engine can stay together and make killer HP with old technology to boot. Well done fellas. V
@Sofiane Ben I have to tip my hat to you Sir. Job well done. !!!!!!!!!
Wow and I thought back in the 70s when AMC went racing with their Gremlin X 258 4.3lilter 7 main.N/A pushing 650hp n 700tq running low 11s 135+ mph. Running side drafts 6 pack of Weber's carbs. 12.1 compression. Shoved 202,168 valves from the AMC V8 heads. Into the 258 stock head. The AMC Gremlin X 258 l6 held the NHRA title for quite a while. It's clam to fame was popping wheelies. Great job guys. Keeping the stock components even better. AMC knew there shit there l6 are stout.
i think your power numbers are WAY off lol. NO way a 4.3L N/A would make 700lbft.
@@3rdGenGuy first off l saw it race I know its set up. AMC l6 were very stout engine. The engine specs are as follows 12.1pop up pistons,solid cam over 600 lift. 6pack Weber carbs. Modded stock 258 head. AMC went racing. Not some private guys. But AMC themselves. They had a l6 Gremlin running low 11s and a V8 running 7s. AMC backing. I think they mit know a little more than you or l. Those were the engine specs on there pro stock Gremlin X.258 package. I dnt think AMC would lie. They were very forth coming with there setup. They used the rods and valves from the AMC 390 engine in the 258. The rods were forged pieces. It wood carry the tires for a easy 10ft. That's torque. I've been blessed to have a gearhead dad that went to the winter nationals in Pomona every yr. Since the 70s till now.
@@Al-mx6ru did it have nitrous on it?
@@2011metalmaniac all those passes were N/A. AMC held the l6 NHRA title for like 20 some odd yrs.
@@Al-mx6ru something just doesnt add up. Were talking about an NA engine, running no boost, no gas, and no nitro on webbers making nearly 2.47 hp per ci. That would mean at 2.47hp per ci. A 426 hemi with a 12:1 compression would not make that (1050hp). The only engines in those times that i know of that would turn that kind of hp with no boost were F1 engines spinning at 14,000 rpm.
AWESOME!! I love seeing old school engines built and boosted..
I have always loved that motor! All straight sixes seem to be great.
I didn't know that you can push this old technology that far beyond stock. Happy to see this.
They are the best
Great Job! I have felt like for years this engine was capable of so much more, as many are. I always enjoy seeing someone do different things! We do Volvo 4 bangers.
I just bought a 95 jeep Cherokee it was a barn find in outback Australia blistered paint and all the typical stuff no dents no rust hadnt been used for 4 years. New fuel pump started straight away. Now that i have been reading about this motor i dont want a new 4wd. Jeep got it spot on. I will get a new paint job and keep this magic little beast.
Those 4.0's were always a strong engine.. loved mine and it outlasted the Cherokee... that's seriously impressive numbers! Those that say it can't be done simply haven't tried hard enough!
It's awesome to see someone meet and exceed their goals, congratulations Newcomer!
Thanks!
A lot of people think water/methanol injection is basically snake oil. On naturally aspirated engines, you see very little gains, if any. But when you use it correctly on a forced induction engine, it works. The engine really responds to the cooler, denser air if it's tuned for it.
Absolutely true
I like weird engines, I always thought Jeep 4.0 were awesome engines that deserved more aftermarket support and this video proves the engines potential. Also wanted to shout you out for the good video editing and no filler, just info and results.
Great build and thank you for using mostly stock parts and showing their potential. 👍👍👍👍👍👍👍
nothing left even remotely stock,the "previously but no longer" stock head would cost 5x what the best aftermarket aluminum head you could buy would cost.thats close to a 100 hours of labor at $200 an hour easily......the block is almost full of block fill and would die a quick death in anything but short dyno runs or drag strip runs
trillrif axegrindor I meant using stock parts , they are modified but stock parts nonetheless. You should try building your own stuff and stop paying $100 an hour on labor. Just because you use your credit card to have stuff built doesn’t mean we all do.
@@juanf4739 So when was the last time you ported heads and balanced a rotating assembly???

How can u get 500 NA HP ??? From a I6
@@cumminsman4670 a million RPM
We don't see many of those straight sixes here in the UK but the ones I have come across from time to time always sound sweet regardless of the mileage and level of sympathy the owner has bestowed upon them,we had similar engines over here but they are long gone sadly.Most of the stuff we do now is 4+6 cyl Duratec based,the last old engine I worked on was a Chrysler/Jensen 6.3 about ten years ago.The best part of that was seeing what is essentially a dinosaur push out 860 hp and 850 plus ft lbs, mightily impressive.even non boosted that low comp engine was stout and outperformed the factory spec by a country mile. What's not to like,top stuff.
This 4.0 the Ford 4.9 and the Chevy V 4.3 are all torque monsters. Nothing surprised me but the numbers. That's massive! Long strokes make gas look like diesel (minus RPM)
Now somebody needs to get that into an AMC Eagle and show up at the next Pike's Peak run.
THAT WOULD HILARIOUS TO SEE THE LOOKS IT WOULD GET AND AWESOME
WOW!!! JUST OUTSTANDING! Congrats on that build.
Newcomer is the best. I'm saving my money to buy an engine from him. Pair that with a transmission from Precision Transmission in Amarillo Tx.
Imagine the shock on someone's face if this engine was thrown into an late 80s early 90s jeep Cherokee and they heard that turbo and saw the launch from this bad boy.
A Cherokee with 800 hp would be such a flex
I love these ridiculous builds. And I mean ridiculous in a good way
My 4.0 jeep kept feeling like it was loading up on fuel, slight misfires, stumbling, ect. Finally I heard what sounded like an arc, I could hear it but couldn’t see any spark. Came across this video and tried it. 2nd plug I sprayed! Ceramic on the plug was cracked! Replaced and runs like a sewing machine again. Thanks for the video
Beautiful work, love seeing that AMC I-6 not just get to stretch it's legs, but fly faster than anyone could have ever imagined for a relatively unchanged design decades older than any other continuously used I-6 family.. In a weird way it shows the AMC I-6's have a lot more in common with pushrod American V8's than any european or asian I-6.
That waterpump hack so you can strengthen bored walls; just brilliant! Newcomer are legends
Mr Newcomber, you sir, are genius! Well done!
I would buy that motor and put it in my daddy's Jeep I wouldn't even tell him I'd wait for him to hit the gas
@@Future-Preps35 well it's one thing I've always learned yes to Creature Comforts have to stay so you build a bracket for it yes intercooled there's more of that great be creative you don't necessarily have to have the intercooler behind the grill you can always have it just under the hood even Up on the Roof her hell you just have the turbos hanging out above the hood or out of the fenders you can even hide the intercooler more toward the bottom of the engine compartment pick up air from blow the frame
Awesome stuff yall, always been a decent fan of the 4.0L worked on several rigs that ran them. Never really seen anything built like this .

CONGRATULATIONS ! !

SMASHING IT ! !
:::nonchalantly pushes dyno throttle::: "what record?"
I would love to see this with a Ford 300. I wonder if the little extra displacement would do much
It's not the displacement that would help, it's the fact that the whole block is made for the displacement.
A 5.0 could easily make more power if it had an equivalent head.
The Ford 300-6 can make a lot of power but the real issue is the head. I saw one guy take 2 or 3, sorry can't remember, LS heads and put them together for the engine. There are ways of getting around the factory limitations if you don't let people convince you it can't be done.
The head is going to be the limiting factor. I think the 4.0l is probably the best head of all the old school inline 6s. Lump port chevys seem to do pretty well too though weirdly.
In Argentina we use the Ford 188 and the 221 cubic inches. They are famous to rev up to 9.000 RPM naturaly aspirated with a mild preparation and pump gas. I would love to see a Ford inline six naturaly aspirated the way it is modified in the US.
@@Falcon_Futura The shit that's done to old I6s in Argentina is incredible! I wish there was more information and or parts available to idiots like myself who only speak/read english. I'd love to get my hands on one of those DOHC 'cherokee' head setups that I believe exist for Turismo Carretera?
I drove a Cherokee up to 200,000 miles in the 90s. This was really fun to watch. Serious power! Nuts.
My second favorite motor ! I just love the I-6 engine so reliable and easy to work on and smooth as glass when running properly.
ANYBODY UP FOR A 4 WHEEL BURNOUT AT 70MPH. ,,,, OORAHH !
It makes me so happy to see these old american inline 6 engines get pushed to such high numbers. The japanese inline 6 engines are so famous now pretty much just as famous as the LS. I knew there were tons of common inline 6 american engines in Jeeps and other vehicles that would probably be able to make just as much power with the proper turbo setup. It's so cool to see people finally doing it. The inline 6 is just such a good design. Why do you think all of the best diesel truck engines are inline 6. The price of 2JZs is starting to get astronomical. And really they aren't that special. Here we can see that pretty much any well setup turbo inline 6 can make big numbers. You don't need dual overhead cams when you have turbos. And it just makes everything that much simpler. This is actually something I had been dreaming of doing myself but without the time and money to do it I'm so happy to see others stepping up to get it done! There old jeep engines are so common and cheap. Great to see them getting used to their full potential. Time to start making some adapter kits to help others get to the same level. I'm sure there will be people interested.
This is about the most braindead comment I've read in a month. You clearly dont know shit about mechanics
I was thinking the same thing... These engines are everywhere and less of a “fancy” setup and older design than a 2JZ... No VVT, 2 valves per cylinder, pushrod design... if Chrysler evolved the design of the Jeep 4.0 they could have had themselves a screamer.
Did you just compare the Jeep IL6 to a 2JZ? The only thing they have in common is their basic shape. Haha, a 2 valve push rod vs a dohc 4 valve. Yep, samesies.
You are totally correct. But i have to say that you are also partially wrong since people have been messing with the slant 6 chrysler for years. What people should be doing is figuring out a crossplane head design which for a i6 engine would entail making one into a overhead cam engine
They should take a look in Argentina, for the 24 valve head developed for the Cherokee engine used in racing there.
just found this video and the straight six seems to never disappoint when i start thinking of what to do on my next motor. definitely going to be putting a lot of the components used in this video in my next build!
I followed this build and one other build for mine and am still in the works of doing more to mine but I turned it down cause it's nice and very controllable at 5psi ...it's still fun my trans and tcase just won't take much more than that ...but boyyyyy when I swap the trans and tcase my f9 inch axle in the rear is built for 800 + whp I will then turn it up to close to what this is ...luckily I live near to where Kieths shop is so wouldn't be hard to have him tune it once I go full send on it
What a cool set up. Simply amazing!!!
Take a deep breath "know it all" commenting.. Love it, great 4L build. Ive had a 4wd ZJ to daily in HS and a Trail Rated WJ ever since, and just now about to sell the last one. 4L is astounding but Im just not crazy about a solid front axle daily...
I like how yaw fully explain everything
Thanks!
My 88 Comanche Eliminator was a badass little truck. It lasted close to 25 years (September 1987 - MARCH 2011) and over 300,000 miles. Many trips to and from Florida to N.Y. Thanks for showing that an old work horse mil can put out high H.P.
Thanks for sharing. I've been waiting for this for about 6 months.
Thanks!
I wish there were more after market for these beast engines
With a Flat Tappet cam, a stock head and no vacuum pump. That's amazing!
Awsome! Well done!
The sound of naturally aspirated was spectacular! Put it in a 70's cherrokee and watch people's heads turn! Then do the same with the turbo and they'll turn, tilt and scratch their head! They'll think it was converted to a hellcat or lS swapped. He He 😛😁

Brains and tech, have come a long way.
If I needed one of these builds, I know where to go. Thanks, Fellas.
This is what American ingenuity looks like!! Fantastic. Granted there were a lot of development and custom fabrication but this shows what the old engine is capable of. This is how much HP & TQE the factory left on the table. This turbo I-6 made more HP & TQE than some of the LS engine swaps from other fabricators that goes into the late model Jeep JK Wranglers!!
....casually looking at XJs on craigslist now
LMAO
I would love to see this set up at the track lol!
Something you just don't see on most any other engine configuration is that nearly flat torque curve. Awesome build guys.
Not a jeep guy, but always cool to see a quality/thought-out build. Good stuff.
What an absolute madman. I love it.

Yes. Tons of aftermarket support for the old Fords
Stock crank, amazing in it's own right
Glad to see a modern build of the AMC straight six. Always liked Barry Navaro 199 straight six AMC for the 60's indy project that did 700hp.
That man is an artist and his creation is beautiful. I'm not crying, you are. 😢😢😹😹
That was sickkkkkkkk! Blew my mind.
Outstanding video
Thanks very much! And thanks for watching
I knew these 4.0L Inline Six engines were awesome but I had no idea they were that capable. Now you're going to get me in trouble again. Might be time for the Holley system, header and head on my old 97 XJ.... :-)
INSANE! Just happy to see people out there doing something different! So BA.
15:58 sounds like a 671 Detroit that gets a 500 shot of nitrous.
Meanwhile im here just happy I can get about 8 psi on a stock 4.0 with 200k miles without it blowing up.
That's still pretty awesome.
It's all in your tune man 😁
My Kenne Bell 1.33L makes 6lbs on the 4.6 in the LJ, boost makes the in-line engines a joy to drive.
Seal’s
That's awesome! 8 psi is still something more
That power curve is SO DAMN FLAT, I love it so much!!!
That was what struck me, as well. Right off idle it was almost all there.
Which makes it super driveable on the road but will cost some hp at the top.
I owned a jeep with that motor for about 12 years. Never let me down
I have 3 of these motors still running with over 400k on them ..... oil leaks tho lots of oil leaks
I have a friend that's a mechanic and he said there's something wrong with your 4.0L if it isn't leaking oil.
mericuh ?
Looks like a straight contender for the 2jc and Barra Ford guys.,! Can only imagine with a race built head and better turbo.
I like this build it was a good watch and the number is impressive. But Sorry Not a chance against the 2JZ RB30 or Barra .... sorry.
It won't rev, heads don't flow, ports are on the same side and he's having to use water/meth injection at only 200hp/L to try to keep intake temps under control.
It's an achievement to get that power out of this engine but it's never going to make good, reliable power on the street like most other L6's can.
@@brendo7363 well, to be fair, these things fair better than most other 50 year old design inline 6's, and seeing as the 2jz and barrs are much newer designs/revisions, i think we can cut the 4.0 a break.

Congratulations on your record breaking and thanks for the interesting videos.
It would be interesting to see chart comparisons of a dual outlet header + twin spool turbo or of a dual outlet header + non-sequential twin turbos.
Combined versus dual exhaust comparisons after the turbo(s) (with and without x-pipe) would also be interesting.
I'm sure you're gaining a lot of insight into in-line six builds with these extreme projects -insights which will, hopefully, contribute to improvements for those who desire peak numbers at half the RPMs you are reaching (i.e. street performance).
In considering all the work to increase the displacement of these Jeep engines, I confess that I've often considered swapping in a Ford 300 or Chevy 292. The Chevy 292 seems interesting since the intake and exhaust are on the same side of the engine as with the in-line Jeep engine.
When will the turbo exhaust manifold appear on the Newcomer Racing on-line store -preferably with a dual outlet option?
At least seeing a bare header flange there would be nice.
Are the runners of the turbo manifold of equal length?
I swapped a 4.0 head on my 258 block and have been really missing my long-tube headers. :(
Edit...
I just learned of dual volute versus twin scroll.

I had an '89 Jeep Cherokee Pioneer, now more than ever I wish I didn't sell it back to my grandpa.
