RB26 vs 2JZ | and WHY the RB26 is MORE ICONIC - ICONIC ENGINES #16

What is up engine heads it's time for iconic engines and today we're talking about one of the most iconic engines ever made. The way it was born and the things that it has achieved have forever cemented it's iconic status in the hall of fame of internal combustion.
The engine I'm talking about is Nissan's RB26 engine. A collection of two letters and two numbers known by virtually every petrol-head on planet earth. Now in today's video we will as always cover the history, specifications and tuning of our engine of choice but in this video we will also be doing something we don't usually do in iconic engines and that is comparing two different engines throughout the video.
Of course you can probably guess what we will be comparing the RB26 with.....yes of course the 2jz from Toyota. Now I haven't read up on the rb26 engine in a pretty long time so when I googled it before making this video to refresh my knowledge on a few things I was very surprised to see that the internet nowadays seems to think that the 2JZ is the better engine and the reason for this seems to be all the 1000hp builds and the 2jzs ability to better cope with obscene power. Now I understand that quarter mile racing is the most popular form of motorsport in United states and probably also in Australia and I understand that these two countries sort of dominate the English speaking internet so I it seems that which matters most in quarter mile racing has somehow trickled down into the shared pool of petrolhead opinions and tainted our minds. Now I love drag racing as much as the next guy and definitely do not intend to diminish the achievements of the 2jz. But there is SO MUCH MORE to an engine than it's ability to not fall apart under ridiculous amounts of boost. Saying engine A is better than engine B because it can survive 1000hp longer is like saying CAR A is better than CAR B because it doesn't overheat as fast when idling at 5000 rpm in the middle of the desert.
So today I'm going to try and enlighten you and explain why as a man of culture you should prefer the RB over the 2JZ.
So the official full engine code of our engine is RB26DETT. 26 is obviously the displacement. 2.6 liters. D is DOHC or dual overhead camshaft, E is electronic fuel injection and the two Ts represent the twin turbos fitted to the engine. So what does RB stand for? Some will tell you it's response and balance or even rhythm and balance. In reality it stands for nothing. It's just two letters designating an engine series like SR, VG, JZ or anything else. But despite this I like to think that RB stands for race bred - because it would really be fitting.
To learn where the RB26 comes from we have to look back at the Japanese Touring Car Championship or JTCC. Now throughout its life the Japanese touring car championship would be held under numerous different regulations, including FIA's Group A regulation and would be known under various different names, but it was always Japan's premiere touring car championship, the cream of the crop for touring car racing in Japan, a place where manufacturers could demonstrate the capabilities of their cars and earn the reputation needed to boost sales. Basically the JTCC, later JGTC and finally Super GT was to Japan and much of Asia what DTM was to Germany and Europe.
Now the 1987 and 1988 seasons of the JTCC were both won by a Ford Sierra RS500 Cosworth and even though Nissan succeeded in winning the 1989 season with the Skyline GTS-R they had realized well before that their car is becoming less and less competitive. It had roughly the same weight but was down on power compared to the Sierra. So well before 1989 Nissan started to work on a car that had one goal: To obliterate the competition in the Japanese touring car championship.
Naganori Ito was appointed as the Chief engineer and Kozo Watanabe as the chief experiment engineer for this project. Now the R32 project was a bit of a personal vendetta for chief engineer Ito. The previous generation of the Skyline, the R31, was seen as a failure from long-time skyline owners, enthusiasts and car critics in Japan and Ito bore the brunt of this criticism. Interestingly enough Ito only had to put his name on the R31 project because he was suddenly assigned to it and asked to finish it due to the fact that the original chief engineer Shinichiro Sakurai had fallen ill.
So to clear his name he insisted to be allowed to lead the R32 project from the very beginning.

Nice to see RB video. I asqed for it last video. And i have been w8ting more then half a year.

I think I have some "normal" schizophrenia about this video, because I love both the Nissans and the Toyotas (JDM alert😁). For that I have a MK3 MR2 being restored (maybe turbocharged?🤔) and a 350z used as a daily. Therefore I can't wait to see your upcoming videos (maybe about the VQ...😜). But can't agree with your more. I'd take a Skyline over a Supra just because of the driveability. If I'd want straight line power, I'd go for an LS or a Hemi. Keep up the good work mate, can't wait to see your turboed mk1 firing up😉.

Mr Man, I think you’re thinking of the LS400, which has a 1UZ…

[@tommykun1990]

I think you have it backwards, Toyota actually looked at the rb and all their downfalls and used that to develop the 2jz (this was a rumor I’ve read on the forums so take that for what it’s worth). The 2jz has a more robust crankshaft, oil pump, oil pump spline, bigger bearings, non interference engine, better oil design and ports etc. The rb seems to be more of a brute force design for racing but with much more cons.

[@kilianortmann9979]

Warning: replacing the super obvious yellow marked hose will void your warranty and generate more power. Reminds me of the wine, erm grape juice concentrate bricks, sold in the US during prohibition. They displayed the warning: After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.

[@olivialambert4124]

So in conclusion, use the engine designed for your purposes. If you want an engine designed specifically for racing, use the engine designed for that. If you want the engine designed to survive anything (ie high horsepower) then use that. It really is a lesson to take into the wider world, in my opinion. Far too many people want to simplify things down to "x is better" or "you must do y" when there's always benefits and drawbacks for specific applications.

I am glad you mentioned the block castings and bore thickness because the 2jz is absolutely beautiful in that regard. In fact, aside from the stock head ports, the casting is all around better and boasts better head cooling and oil flow. You mentioned the shortcomings of the r32 oil pump, but you neglected to mention that the rb head fails to sufficiently drain the oil out of the head requiring you to port the drain holes and add larger head studs. Often times, people will "fix" the rb's oiling issues with an aftermarket oil pump, often increasing oil pressure and making the head draining issue worse. Even with the stock pump high rpm for extended periods of time can be catastrophic. Also, I find it a bit unfair to even compare it to the Supra, the Skyline chassis is hands down better in every single way. I really like the rb, particularly the rb30, and I love its sound, but to me the 2jz just seems like the "nicer" of the two. But of course if I am going to choose between a Skyline and a Supra I am going to take the Skyline.

[@20somthingrealestate]

🤡😂

[@911lilslim]

The oil drain issue is as a result of high g forces during forward acceleration so on a circuit it shouldnt be as bad especially if the car had a dry sump system creating vacuum in the crankcase and making the head draining issue worse with an aftermarket pump is user error it means you failed to fit a restrictor to the oil feed on the block. He also didnt mention the 2jz habit of launching the harmonic balancer out the bonnet

[@Skirk84]

Well said, but not only are the head oil drains insufficient but you also need to restrict oil going to the head in the first place to completely solve the problem

[@Skirk84]

@@911lilslim the 2jz does no 'launch balancers out the bonet' they have a standard rev limiter of 6800 non vvti and 7200 for the vvti. If you are taking the car to 8000rpm's or higher youd be stupid not to upgrade the balancer which after 20 years can fail, just like the rb26's balancer. I rev mine to 9500rpm with a fluid damper for over 9 years now with no issues.

[@Brendan.Wheatley]

A really thoroughly researched comparison on these two engines, down here in Australia we absolutely love both of these engines, the RB in both drag racing and touring cars being very successful and the 2J predominantly in drag racing. We have a great after market support base for both engines, yet recently we are falling in love with our own locally designed in line 6 cylinder twin cam turbo engine, the Barra! We are seeing crazy numbers coming out of Barra engines on the dyno, thanks for the great video mate...

[@bigcazza5260]

barras arent as good for racing until you destroke them, otherwise they just blow tires off, even my intech au lights tires quicker than my windsor au

[@clevo_gtr5541]

The Barra is only good for one thing power and unusable torque, As it should its a 4L six that copied the head and port design of the 2j and RB. Good enough motor but they get too much credit for what they actually are. Once again a engine raved about because it can make power relatively easily. Fun fact no barra has ever beat the RB or 2J maximum hp number. lol

[@georgeyoutube7580]

I dont want to upset Americans, Australians and the whole lot where drag racing is popular. But it's 10 seconds at .most. It's intense, it's fun but it's a humiliation to use a combustion engine for that, a combustion engine is overqualified for that job. I swear by god I can win that with a spring powered car or a water rocket shopping cart. It's only the designation as racing with rules that keeps the combustion engines still relevant in drag racing. Springs, catapults, electric motors, rockets, any other device is more qualified to discharge lots of power in a short time.

[@n1njaweedman]

@@clevo_gtr5541 gotta remember the barras haven't seen near the amount of aftermarket development time and effort the RB and JZ have, but great strides are being made and we will see one meeting or exceeding their max hp number one day as they are just as capable.

Of course the RB vs 2J battle will go on till people forget both engines ever existed. When I decided on swapping the 13B out of my FC Rx-7 for an inline 6 the reasons you mentioned lead me to an RB26 as the engine of choice. Nothing against 2J's, I looked at 1J's too since they're unarguably great engines, I just didn't need that much strength for a street application. Always loved higher reving engines and the sound of an RB26 just can't be beat.

[@lqr824]

I didn't realize you could FIT a non-rotary in an FC! As much as I loved my 2JZ, I don't think I'd do the swap you suggest. Just seems wrong to put a non-rotary in! In fact, I keep dreaming of a MX-5 with a 13B, maybe with an extra rotor...

[@Dollsofgod]

@@lqr824 I hear people saying it seems wrong to put in a non-rotary into a rotary chassis car all the time but hear me out, I've owned 4 rotary cars, 2 FC turbos, 1 FC NA and later turbo converted and 1 Rx-8 and only owned 2 piston cars in my life, this will be the 3rd. Like anything if you experience it all the time it gets old and the mounts for the 13BT are still there, ready for the original engine. it's easier for me to make storage space for an engine rather than a whole other car so I decided on a swap. Maybe later on I'll get a skyline and swap the 13BT into that for kicks!

[@lqr824]

@@Dollsofgod Wow, that's a great story! Obviously these are very cool technical projects and you've got my total respect on that. My point is mostly that I'm just very conservative for some reason. I don't like the Corvette name on a mid-engine car for instance, don't like the V8 BMW M3's, and so on. I really have total respect for Mazda's rotaries, and obviously you like them too, so we're in agreement there!

[@friesy3518]

Actually... I’m fairly certain the “B” part in “RB” stands for the German word for benzene (“benzin”), which ultimately denoted that the engine is petrol powered.... since there is an “RD” engine too which has a D for “Diesel”. Nissan did the same thing to denote the difference with their Patrol motors... e.g. “TB42” for the petrols and “TD42” for the diesel variants. Both of the engine blocks for the RB/RD and the TB/TD are the same block with minor alterations depending on what fuel type it was going to be used for.

[@mrman8856]

Lol. You made up a whole fantasy!!! It has nothing to do with Germany at all! In reality it simple means RESPONSE BALANCE

One needs to be significantly richer to own an RB than a JZ. RB are great engines but come with serious flaws that require to be corrected before trying to do something. The RB bad habits to pump all the oil up into the head and let the crankshaft die by oil starvation is one of such flaws. The JZ are straight forward in comparison, even if they are born farther from the race track.

"Serious flaws" sounds like someone who lives on youtube/google. The average person with a tuned rb won't ever see these "flaws". Not everyone is on KZbin running 1000kw and needs to worry about all these "oiling" system issue's. Yes, Rb do blow up, like any engine. Especially when its 31year old r32 that's imported with a wound back odo and been thrashed harder than you can imagine, with the rare oil change. I have been running rb's hard at over 350awkw for 15 years

@@shortybj40 a friend of mine is still owning his RB powered 700hp r33 (could theoretically hold 900+) and we went through these flaws. When he started to heard the engine knocking it was already too late, when opened the hood there was massive quantity of oil that had leaved the engine through oil catch tank, the car was oily to the rear axle. When he opened the crankcase he found the crankshaft was marked. He has been lucky enough to find another engine for a great price. Then he decided to rebuild that second engine to restart from a good basis, using forged internals to hold future big power setups and improve oiling system. Then he made a mistake about valves clearance which led him to re-open the engine to replace valves (heat expansion led valves-pistons contact). Now the car and its RB power plant are really great, it just cost much money to get that nice result.

So he ran 700hp on standard internals, it blew up. Then the engine was built incorrectly and not clearanced properly, and you still blame the type of engine

@@shortybj40 not at all, it outputs 700hp now with every work properly done, both to correct oiling system, and to mount reinforced/forged performance parts in it.

Work on both, then make this video again. The 2JZ couldn't race because of displacement regulations in Japan. The RB is great and all. But the brutal simplicity, reliability and consistency of the 2JZ cannot be beat. It uses way more commonly available parts and less of the factory parts need to be changed to maintain a reliable 400 to 600whp car. The RB has chronic deal breaking issues with oiling and cooling regardless of the generation, the 2JZ just doesn't have those problems. It's always funny to hear the opinions of people who have clearly never built or worked on either engine. 2JZ for the win. Always.

The JTC-1 class, also known as Division 1, was eligible for cars with displacements of 2,501 cc or higher. Between 1985 and 1987 it was known as Division 3.

Really enjoy your videos. Wondering if you might consider covering SAAB's B235 engine in your iconic engines? Another generation is fine, but I had two SAAB 95's that I really miss, and I've read the 95 had a better 60-90 time than a Porsche 911. Maybe this motor wasn't much in the racing and tuning world enough for the "iconic engines" series, but I've always felt SAAB was a very unique company and always did things their own way and outside of the box.

People here don't know the meaning of the phrase GT-Grand Tour, it is a type of car that is superbly reliable with a lot of power (Supra wiht 2jz), while sports car can afford to be less concerned with reliability and more with overall performance. And I would say it is unfair to say Nissan did a bad job with engine block QC or construction, they had a goal and a budget, and most of that budget went to amazing 4 wheel drive/steer system and chassis.

A Grand Tourer has nothing to do with reliability lol, where do you people come up with these things? There's no car class where reliability is a deciding factor for fitting in. A GT car is supposed to be comfy and powerful, like most non-track-focused Aston Martins. That's it.

[@user-or9ey2ld6s]

Great video! I was always under the impression the 2JZ is the better engine because it's stronger and never really cared too much about the RB. This video changed that. (I didn't change that I can't afford either engine tho lol). But I also have some questions left: 1. ITBs are awesome but are they that important in a boosted engine? Since the engine makes all the relevant power and torque under boost, ITBs seem to not have a great effect. Wouldn't pulses from the engine's intake side that would interfere and therefore reduce air flow in an N/A engine be mitigated by the positive pressure in the intake manifold anyways? 2. You showed that the RB makes peak power close to redline and peak torque 400rpms later than the 2JZ. This is of course due to the nature of these engines and makes the 2JZ's redline lower. I don't think this is a disadvantage tho. In some suítuations high revving has advantages, in others high torque does. Comes down to track and driving style I guess. I think both engines are great. Speed Academy are building a response Supra right now. I'm excited to see how a response tuned 2JZ handles.

As soon as you mentioned Australia, I wondered why you are not also discussing Ozs' own i6 Barra - think, 2jz bigger and better brother. I went to roll races a month ago, and there were mostly Barra and LS powered vehicles, and I think maybe one RB30, one RB26 and one 2JZ. Many many Barras and LS cars. Odd. Not to mention that it seems like every Nissan Patrol with a dead engine is being converteed to a Barra here in Oz. The Barra factory cast block and head can make >2500 crank hp. The 2jz factory block can make 1800hp (max) before the deck warps. The RB26 factory block can make what hp repeatably without falling apart ? I couldnt find this info, but, not many people are pushing the factory RB26 block beyond 1000hp it seems due to cracks around the head studs. Maybe some one here can educate me on factory cast RB26 blocks.

Wait, isn't considering motorsport as an argument in favor of the RB not the same as dismissing the 2jz for its racing accomplishments on the dragstrip or whatever? Both are equal to the metaphor of holding 5k rpm in the desert. I used to lean over to the RB as well, before I watched SA's 2jz and RB26 rebuilds/ refreshes. The RB is an absolute mess in pretty much all aspects of maintenance and ease of working on it, coupled with its inherent issues with oil pumps, oil starving and oil pan issues... Not to mention that the ITBs on the RB are pretty much a gimmick, only there for homologation and more often than not removed. ITBs have extremely little benefits in boosted applications.

[@johnnyz1781]

Then we have the exploding cost difference. A 2JZ is still an affordable engine, a lowly RB20 will fetch over $3k now. Skylines should keep their RBs, but any other project, the 2JZ is the I6 of choice.

I agree with your point about power range between 400 to 500 hp for the RB is more "suitable".

Just to point out the JGTC rb26s were not stock, and the wins are mostly attributed to the amazing AWD system of the GTRs and not really the motors a bit unfair how you put one type of racing above another, just how hp handling characteristics is a small part of the overall package so is racing history. also you compared JDM 2jz's and not the export 2jz's which had bigger steel turbos vs smaller ceramic ones, bigger injectors, higher lift more duration cams and a fuel pump strong enough to support 550whp on pump gas. Export models also had better ecus and used a maf/map combo while jdm 2jz only had MAP sensors. export supras with a piggy back ecu,boost controller, bigger intercooler, downpipe and full exhaust have dynoed 420-480whp. the 2jz has a thicker deck height so has less block to cylinder head distortion under high cylinder pressure. Rbs have a slight problem with oil draining back into the sump and water/oil pump limitations (N1 or Nitto pumps solve this) you can shim OEM supra oil pump for higher pressures relatively easy and remove the sharp edges in the oil passages and that's all you need for reliable oil pressure and volume on a wet sump 2j (modded oil pumps are half the price of aftermarket rb ones). Shim under bucket and Shimless buckets are huge plus on very high revving motors especially when using high lift cams, but lets face it, if you are gonna swap out cams you're gonna have to get new buckets to set correct valve lash so the all toyota OEM shimless bucket conversion would be included then, as its not necessary for the OEM cam profile.

[@Skirk84]

I am 100% not a drag racing guy, but there is a thousand reasons to choose the 2JZ over the RB26. To start with the 2JZ is lighter than the RB26. In stock form the 2jz makes more power, more torque and doesn't suffer from any issues. Where as you can't go around a hard corner with the RB26 without it dropping oil pressure. Not only does it drop oil pressure but if you keep the revs too high for too long you will go into starvation and destroy the bearings. The RB26 stock turbos can only handle 15psi before they explode, where as the 2JZ turbos are good for 23 + psi and 350 + kilowatts atw. The only thing stopping at 2JZ from revving to 9500+ RPM is the fact that you want shimless buckets after 9000rpm. RB26s have a range of problems over 8500 RPM. And these are just the issues with the stock engine, hardly a race engine. Anyone who is putting a small single turbo on to either of these engines is going to push upwards of 500 hp, which the RB26 cannot reliability achieve. Which means a lightly modified car needs a $25,000 built engine, where as you can have a race car or track car with a stock bottom end 2JZ which will last you many years. Issues the RB26 has that the 2JZ does not. Oil draining issues, oil pump issues, crank sensing issues, poor crank resolution, weak coilpack setup, no variable valve timing, thin bore walls, weak block construction, small headstuds, small oil drains from the head, weak turbos, noisy lifters and just a poor head cam setup to begin with. Less capacity due to shorter stroke but still cant rev as high? Yeah the RB26 is more comparable to the 1JZ but still not as good.

[@glennandrews5103]

Honestly this whole which is better is annoying because by the time you spend 20k on a RB30/26 with all the fancy parts you can literally buy a race engine or billet block hahaha. 2jz or 1jz far better at cost to gain and like you said 10kg lighter and basically no trigger setups needed to make it big. And the material of the block is far far better and stronger.

[@janvotava9792]

RB has 12 mm head studs, 2jz 10mm. RB has stronger crank bed, beter cooling cause of bigger spacing.

[@efiniGTX]

Why are most of the arguments not related to the engine itself? The ATTESA ETS, compliments and takes advantage of the motor but doesn’t make the RB better. The racing heritage is a strange argument when bringing up the inherent design flaws of a “race” engine. Both engines are great in their own right, but there should be less bias in the assessment.

[@blastor8030]

True, the structure and the design of the car would be better for racing, but the engine, I think not so much actually ... What was not said in the video ... 1- In the Japanese Championship, the only vehicle that had 4WD was the Skyline which gave it enormous advantages against any other competitor 2- The RB engine displacement was the HIGHEST of the entire Japanese Championship starting grid in the years of the GTR's dominance, there were competitors who had much less displacement, 2,000 or 1,800, but no model of that time had more displacement than the RB, including the BMW or Ford Cosworth 3- In each of the races of those years of dominance of the GTR in Japan, there was no other model with more number of vehicles on the starting grid than the GTR, in some championships there were even up to 8 Skylines for every 2 BMWs or for every 2 Fords. There was a 4 to 1 chance that the winner would be a Skyline. It was difficult to beat a vehicle MODEL that had 3 advantages that the other models NEVER HAD.

[@Erelyes]

A great overview of the two engines. I feel like a few additions are worth putting in a comment. Firstly, as another commenter mentioned, the RB suffers from poor oil drain to the head. Generally it requires a restrictor (to limit oil flow to the head) as well as external drains. The second thing worth noting is that the RB has a far wider range of engines than the Toyota JZ. The JZ comes in 1JZ (2.5L) and 2JZ (3.0L) variants. The RB came in RB20, RB25, RB26, RB30, and even a rare and unusual RB24 variant. A lot of these were fitted to more standard production saloons rather than the firebreathing GTR. That said, by and large these motors can also be tuned very successfully, and so 'back in the day' the RB was a lot more accessible and familiar to tuners generally speaking. Of course nowadays, most RB-powered cars have been crashed, thrashed or trashed, so it's a different story!
