DL Cummins 6BT vs Toyota 2JZ Which Engine is best?
Вставка
- Опубліковано 9 тра 2019
- Which is the greatest inline 6 engine of all time? The Diesel Cummins 6BT or the Toyota 2JZ? Yes that's right we are comparing a diesel vs. a gasoline engine and the results are going to surprise you. Both of these engines are notorious for being over engineered and for making a ton of power. But which should you choose for your swap. We break them down piece by piece.

Why are you comparing these engines? Seriously.
is like oil and water 😂 should be either diesel.vs diesel or gas vs gas
Yeah ones high torque ones high rpm depends on what your building, comparing them is kinda stupid since they're built for different purposes.
why not compare them? They are both ICE engines. Its like saying "DON'T COMPARE A CARBURRATED 5K RPM ENGINE TO AN IDIRECT INJECTED 8K RPM ENGINE BECAUSE THEY ARE DIFFERENT"
Dude its just a video for entertaining purposes. Who cares
Why your argument? both are awesome engine... a competition is not bad at all.
2JZ = best for having fun
6BT = best for getting shit done
Probably most of the 2jz cars were delivered to the dealers on the back of Cummins powered trucks.
No you can put a 2jz in a truck did it to my moms silverado
Shut up, cummins is fun
OM606 = having it both ways!
who said you can't have fun with a 6BT. Roll coal, listen to that turbo whistle and run extreme amounts of boost. In a diesel you don't care about knock. Just shove into it as much air as you want.
well being that these are my two favorite engines ever created, that’s a hard choice lol
How about a middle Way between both? Om606
I'd take a ppumped 24v over a 12v
Yea the om606 is better that 6bt
The wallet is the limit when getting numbers out of these 2 engines. Whoever has more money on their engine will kick the other ass. Both engines are incredible. Both 2JZ and 6BT can achieve 2000hp with thousands of dollars behind.
It also depends on the application. The 6bt with 2,000 hp will have heaps more torque and usability for towing or moving a 8,000+ lb truck. But the 2jz gte in a supra or light car will be much faster (like drag racing). Both are cool in their right application, and I think we, the viewer, are the real winners. Not to mention, big hp numbers are usually a "whose daddy is richer" game. And the real fun is watching them destroy hundreds of hours of work and tens of thousands of dollars in mere seconds on a dyno.
A lot more then $1000 for the 2jz for those numbers. I have both motors and making 500whp on my is300 costed $10,000 in parts. 6bt 12v you can just turn a few screws and your laughing all the way to 700hp with under $1000 all day. 2000hp would most likely be like $16000-$18000 with good parts. Tough comparison!
2JZ- Great engine
6BT- Fucking legendary
12 valve Cummins will go a million miles with just regular maintenance. It will run exactly the same with or without a wire harness. And run on almost every type of oil for fuel, if it's heated or thin enough to get through the filter. The 12 valve can also pull an 8 ton trailer and still get 17 miles per gallon. You have the option to go with a highway tractor or all the way to a drag truck. And 1997.5 and older are smog exempt.
I love working with these babies on the regular (work at a dodge dealership) that 6bt is no joke just wish some older trucks would come in sometimes
1998 and older are smog exempt. Mine was made Christmas Day of 97 has all the goodies the 24 had besides the engine harness
Shit i forgot to mention it’s a 12 valve. 1998.5 was when they went 24v
@@derkaderkastan420 yeah the model year has to be a 97 to be smog exempt. The 98 model 12 valve has the newer computer with the three plug harness. It looks the same as the 24 valve. Pretty much needs to be smoged because it has a newer wire harness for the 98 model dashboard, everything else is the same as the 97. Ordering parts gets a little annoying. The 12 valve parts will say 94 to 98 and the 24 valve will say 98.5. I think all the 12 valve quad cab's are 98 models as well.
lacquer head I’m smog exempt I promise. And yes especially transmission parts is extremely annoying. I have the second generation style nv4500 so no speed sensors on transmission and the shift tower is that weak one that likes to snap off.
When both engines race& the 2jz motor blows, you can still tow it with a Cummins! $$$$$$$$$$$!!!!!! Also, I’d like to see a car go through dirt like a 4x4 ram!
David harrell why would you take a rwd CAR through dirt and compare it to a truck? What sense are you getting out of this?
Gaming Nation Did you not see the video comparing them or are you that moronic!
@@davidharrell8890 your an idiot lol
What about the 2jz rzr on you tube... it's plays in dirt very well
Not to mention they are comparing motors.. not cars
5.9 vs 2jz? Why would you do that. Could have done om606 vs 2jz both 3.0 inline 6 both from factory can make hudge power on stock internals
Because people underrated the Cummins.
@@FEGTTTSDH who underestimates the 5.9 its called a legend for a reason
Om606 is German cummins
24 valves diesel
Om606 and 6bt Love ❤️ both equally amazing engine 1,000,000km and more with maintenance.
Well, to tell the truth; both are inline 6 as well as overbuilt and bullet proof. The 2jz, 6bt, and LS are the most popular performance engines in the world.
The Cummins holds nearly all of the performance records in diesel pickups
There is only one diesel that stands up to the 6BT in terms of being tunable: the 6.4L Powerstroke. However, with the emissions systems, it is notoriously unreliable.
@@bcdieselsofficial the 6.4 ps has a noturiously weak bottom end
@@justinmartin8887 actually, the connecting rods on the 6.4 are the strongest of any Powerstroke. It’s the pistons that are problematic.
BOTH ARE OUTSTANDING, TOP IN THERE CATEGORY ‼️‼️‼️
Imagine if the 2jz was diesel and this video made sense
What about a 24v cummins🤷🏻♂️.. and as far as I know they don’t have “lack of coolant flow” issues, they just don’t displace fuel properly because of the intake being so far forward causing higher egt’s toward the rear which can be fixed with a twin ram intake.
24 valve is a 6bt with a different head and vp44 pump insted of all machanical (also a different cam because it don't has to drive a injection pump off it) and 12 valve head basically
The 03 to present (5.9 and 6.7) Cummins, have the turbo flange mounted to the rear, on the last 2 cylinders.
This causes more heat to build up on #5 & #6 cylinders also causing hotter coolant temperatures to stay at the rear of the block, this can cause ring and piston damage if coolant temperatures get to hot.
That’s why Fleece Performance came out with the coolant bypass to help eliminate this problem.
Alot of guys will just do a second gen (98.5 - 02 ) turbo swap to eliminate this problem and evenly spread the heat across all cylinders.
I have tested the temperatures on my 6.7, with and thermal thermometer, comparing the rear cylinder temperatures to the front cylinder temperatures, they can from 30 degrees and up depending on how hard you are working the engine .
There are vids out there explaining it better.
@@shawn8363 I never knew that , I herd about 2nd gen swaps but didn't know why , great info!!!
boosted garage
Second Gen swaps are all around better, not just for the heat build up.
You can get a better, more powerful turbo (depending on what you’re doing with the setup) and the regular turbos are by far more reliable than a VGT turbo.
The second gen swaps eliminate alot of problems.
Funny thing is that a High end BD diesel second gen swap kit is about $3,000 for everything down to the turbo gaskets and brackets, everything.
A rebuilt VGT for a 6.7 is $3,000
I plan on doing it to my 6.7 in the future.
@@shawn8363 just a note, oil temperature is probably more important than coolant temperature in a diesel because under normal driving conditions egt's are low and the coolant is not stressed. The oil is what keeps the pistons and rods from seizing as long as it doesn't sheer and lose lubricity. The coolant is what keeps the head, and sometimes the turbo temps steady (but again oil lubricates and cools the turbo primarily). Highly modded trucks will obviously benefit most from upgraded cooling. Again, I am coming from a mostly stock stand point, and it never hurts to give an engine an efficient and powerful cooling system.
I think modern 24 valve engines suffer because the exhaust manifold is not centered for the turbo, and creates more of a restriction for 2 of the cylinders unlike older gens that center the turbo on the manifold. But really, an aftermarket manifold that gives each of the cylinders an equal chance to breathe is best.
Plus the 24V in the dodge ram has that stupid cooling line that runs below/beside the exhaust manifold/head and runs behind the engine, which is absolutely stupid and can not be efficient for cooling whatsoever. You know, the b.s. line with the "y" pipe and rubber boot by the bell housing that seems to weld itself in place....that one.
Why would you ever compare these though?
Mercedes E300TD essentially is a diesel 2JZ and it is right on par with a standard 5.9 and revs higher
And the om606 is a car motor just like the 2jz... why compare 5.9 that spins at 3k to a 3.0 that spins 7k
My plan is to go for about 300 HP supercharged and stay at that for reliability reasons. I think ill take the Diesel.
Turbos are better on diesels.
How is the valve train comparison fair? They gave the advantage to the 2jz cuz it can spin more rpm? Like the Cummins doesn’t need more a ton of rpm. It’s a truck motor and it makes peak torque well below 3500 rpm.
If you want have fun, 2JZ is answer
But if you want to have fun, get shit things done, pulling out work without broking transmission, Cummins is the answer
A 12v or 6bt Cummins will not handle 60-100 psi boost without upgraded head studs, steel oring head and aftermarket head gasket. Stock Cummins head bolts will stretch at 50 psi of boost, and the stock head gasket wouldn't handle enough boost to get to the point of stretching the head bolts anyway. They will reliably handle 35-40psi of boost, but like anything abuse it enough and stuff breaks.
I’ll just take both a build a sweet diesel build and mk3. Am I right?
Vincent Petro mk3? Why not a mk4? Way better in every way
I want a mk3 eith a cummins
ford barra bro
I f'n love the barra!
It is funny to compare there to engines but why not. Best petrol engine vs best diesel engine. However the stock 2j can handle alot more then 700hp. The are plenty of 1000+hp stock internal 2j's getting around these days. Worth mentioning the factory 2j oil and cooling system is adequate for 2000hp, the factory ports and valves are good for 1800+hp and the factory iron block has done a 5 second pass with over 3000hp. Also it's not uncommon for 7 second supra's to run factory cranks. All that being said the 6bt could use a 2j as a source of induction.
1100lb-ft vs 500lb-ft a tie? the Cummins is literally more than double the torque, how the fuck is that a ti
The barra beats em all . Best $500 motor on planet earth 😎
Best is Mercedes M104. Costs about the same.
@@TTURBOVOLVO thats correct mate that is the best AFTER THE BARA 😉
@@mickm2999 👍🤙
Eggs vs towels, which is best?
Cummins b series wins. A heavy duty mechanical diesel found in commercial 25t trucks, gensets, wheel loaders, excavators, marine use etc and still being built today in varied series. The 2jzgte is just a one hit wonder, tho' an almighty punch for its size. If it was soo good it would still be made today for various power applications.
Cummins nuff said. Besides I'm American so is cummins, lol.
6b💪
Comes down to application
Cummins all the way torque monster.👌 mint
Because they are diesel engines tho
@@carholic-sz3qv still they dont self destruct easy
Cummins for sure
Woow diesel handles more boost and power, i wonder fucken whhhhyy 😂😂
Just three words SIMPLICITY and IRON BLOCK!!!!!
You can put 2jz in trucks but you can’t put 6bt in small cars😁
What about 2jz vs om606 that would be a better match up
1:16 obviously ignoring the Killer dowel pin.
Its easily fixed with a block off plate plus if your making a top speed engine that's probably the first issue you fix.
COMPARE: 6BT vs 1HD-FTE
I’ll take anything made in Japan over anything made in Indiana.
I mostly agree, but just remember the cummins is one of the most popular, versatile, and frequently used engines in the entire world. It's in pickups, box trucks, dump trucks, over the road trucks, generators, pumps, utility trucks, and even boats. 2jz's were in a handful of toyotas. And, 2jz's are only popular in a few forms (such as the supra, the most popular). But, Japan makes some excellent stuff and vehicles (overall quality) are on that list. Indiana isn't the best showcase vs Japan. I think they have corn and like...rocks...or something. Despite its lazy looks, the new supra is going to be a legend. Yes, I think it's ugly. Toyota should have stepped up their game for the new supra, instead it looks like the 86 slammed and widened. It should be wild and exotic, but it looks plain and simple. In fact, the new 86 looks way tougher! But dat engine doh! It's gonna be a game changer and future generations better look at the new supra the same way we look at the old supra.
Get a duramax then. 😂😂😂 fucking Isuzu Chevy fanboys hate it when you point ya that out.
@@derkaderkastan420 LAWL!! SO TRUE!
This is one of the few exceptions, cummins is a million mile motor. There is a reason you can't find a first gen ram cummins with over 100k miles for under 12 grand
Adam Webster nope and a second den 12 valve with 400k for less than 7 grand
Yes.. why are you comparing and orange to an apple?
The 6bt has a major displacement advantage. Compare vw's 1.8t to the 1.6tdi. I'd like to see an evenish comparision.
Rpm has a big factor as most 6bts aren’t anywhere close to 5k rpms
@@derkaderkastan420 they redline at 3k last time I checked, you can get some governor springs to boost a little bit but not a lot.
Zach Steele 2750 in the 12 valves. Governor springs 4k in the ve pump and over 6k in a p pump setup.
Cummins!
The 2JZ was designed for play, and the 6BT was designed for work.
You can get serious performance with the BT, sure is more a swap for a truck or somes 4x4.
The cummins in my landcruiser
I know, let's compare aircraft to cargo ships! This comparison doesn't make any effing sense! A petrol/gas car engine to a diesel truck engine? Someone explain.. on second thought, don't I can't laugh right now, it'll tear out my stitches.
2jzgte better in my opinion . Everyone now days but them to abuse them add hella ho in stock block because they can handle it . Eventually they break like any other engine don’t last forever . But 2jz definitely one of the best engines it’s on top with the ls from the corvette .
Well thing is Tractor/truck pulling exists. Lost of abused 6bt's there
Here's a really simple and easy answer. The 6bt weighs more than twice as much as the 2jz and can make similar power, but more torque. If you need to do anything but drive in a straight line, then the 2jz wins every single time. Its the same reason your buddy's miata is faster than your mustang in the canyons. Turning matters.
This is clearly done by people who like 2jz motors
What a stupid question
These engines are so different how could u even compare them
Ok diesel engine weighs like 2 1\2 times that of the 2jz... You can't put it in a car without modifying the suspension smh this is a dumb comparisons! !!!!!
thats not a oem 2jz rod.
2JZ...
This is a dumbass question. Why would a garbage Toyota gasser engine ever be matched with a solid diesel unit like this? It makes no sense.
I have yet to see a million mile 2jz
2JZGTE for the WIN
A better comparison would been the common rail 24v isb block. Electronic fuel injection 4 valves per cylinder.
Dont you mean 2jz vs om606
2JZ-GTE all the way, never heard of that other Engine.
You can't compare a gasoline engine with a Diesel engine.
6bt is in dodge pickups in the U.S., famously named the "cummins", also used in UPS trucks, and a variant 4bt. 24 valve 6bt is a beast, but being diesel not many "car guys" are interested. 2jz-gte is an exceptional design but the barra 4.0 is right up there. I don't think we have the barra blocks in the U.S., but maybe we do and they are just very rare. Anyway, most diesel engines are going to be able to hold more boost than a traditional gasser, because diesel engines are built thick, heavy parts, extreme fuel pressure, high cylinder pressures, and they are designed to work under heavy loads. But with these heavy duty parts comes a lower revving, heavier engine assembly. If you have time look up cummins swaps, some are pretty cool. There's a famous one called (im not making this up) the cumstang. Cummins swapped mustang. One disadvantage to the cummins is the height, its basically a 2 story building under your hood.
@@rhawk2424 6BT? 4BT?
@@toyoscio yes, cummins engines. 4bt is a 4 cylinder, 6bt is a 6 cylinder. They are "universal" engines, not specifically designed for one particular vehicle. So companies that choose to use them, usually have to design the engine bay around the engine, not the other way around. That's why we don't see jeeps running zetec ford engines. But we do see jeeps running 4bt engines.
@@rhawk2424 Thank you. I see now.
Wow.
I would like to see a Cummins beat a Lamborghini
your on youtube dude... look it up😒
Anything can thwomp a lambo when tuned
There are tons of cummins drag trucks that run 9's in the quarter all day. Aint no lambo gonna run 9's in the quarter bud.
Both.
Cummins cause u can put more horse power nd torque not just that u can refresh the sleeves nd make it new again. Which the 2jz also is good but u cant do what the Cummins does
It is diesel vs gas
6bt vs Barra
6bt
The diesel ⛽
A more accurate comparison would have been a benz om606 and a 2jz not a loud leaky over hyped 6bt
Overhyped the 6bt? but not the 2jz?
6bt overhyped? Best diesel engine on the planet. It might leak, but that just means that you don't ever have to change the oil.
this video is in the realm of comparing two things that are nothing alike..............made for completely different applications. like wtf?
CUMMINS 6BT duh!
#murica
Dumb comparison. They are COMPLETELY different engines designed for totally different applications. They aren’t even remotely similar to each other than they are both inline-6. One is designed to work and the other is made to go fast. The end.
What kind of question is this? Cummins all the way!! 🇺🇸💪 great video!
Toyota 2jz vs Mercedes Benz om606 🤦🤦🤦
Idiotic comparison, the Mercedes om606 3L diesel would be a fairer comparison to the 2j as it’s known as the diesel 2jz,
Both are incredibly internally balanced to withstand 1200+HP WITH FACTORY INTERNALS.
I will use my awesome 6bt to tow my awesome 2jz to the track
Apples to oranges
Its stupid to even compare these two
And the cummins wins hands down
not even close to in the same category,
Stupid to compare diesel and gasoline engine.
Small minds cant see big similarities
6bt, not very good for making 2000hp
