I think we all just learned why Nissan never publicly state why their RRR block is better. The answer... it isn't. Purpose built for the task, and only expensive due to the limited production run for motorsport purposes.
I feel like it should be remembered that they're talking about 1000+ hp drag racing builds here and it's not like the RB are suddenly junk. They're still a capable engine.
@@MotiveVideo My take on it is, it's a perfect engine for 500rwhp all day everyday. With good water and oil flow. You build the engine around what it was designed for. You want a 1000+hp drag racing engine, go billet. why on earth would you go stock and risk spending more if it breaks? You want circuit racing limited to 500hp or perfect street runner, GT500 block.
@@Monstero5o because 25/30 works around the struggles vl owner's have or are you referring to one and the other? Looked as if you were talking 25 top end and 30 head down
Billet blocks are designed from scratch with 3D/CFD software, so they will know everything about it before it even goes near a CNC. You can't directly compare cast iron blocks with billet aluminum based on simple measurements alone. The way they behave under heat and stress is a lot different, billet blocks generally have improved oil flow, larger threads available for head and main studs with extra meat to accommodate them, as well as ductile iron sleeves.
You have to define 'best'. best for what? From an engineering standpoint, it becomes financially wasteful to design strength and capability much beyond what is required. The RB blocks meet the requirements for the applications. they destroyed the competition in all racing they competed in, which was their design goal. Nissan never intended for the 2nd hand, aftermarket scene to be driving 1000+ hp drags etc and hence never wasted resources on it. The 2JZ block is stronger and better for the latter, but was also never designed for it, so while we all love them for it, you could argue its design was less appropriate to its requirements and may have soaked up money better spent elsewhere on the car, rather than building in such a large 'factor of safety' for benefits the company will never see. Decades later, we know which one can do what in far more detail then the manufacturers ever did and which block is better for what. Its an interesting thought.
Also kudos to herman throwing those million dollar words around like its easy lol malleability... bro i would have had to do that take about 30 times to say that correctly LOL

There’s one on gumtree right now going for 10k. I did a quick search on rb30s and found one for $100. Nismo aren’t stupid though, they’ve done only what they needed to in regard to not over engineer the block and the demand for the blocks warranted the prices. Still kinda cheated us though...
Finding a good and strong block isnt a easy task. There are 3 main things that keep your engine from failing. 1. Machinist 2. Engine assembler 3. Tuner An RB block has its weak points but there are other factors that keep alot of these 1000hp rb blocks still performing. Certain upgrades that need to be done with them such as billet main caps and girdles. Heat and pressure cracks bores thats why making power with better fuels is necessary. Fuel like ethanol and methanol is such a big game changer and why most GTRs are able to run 1000+hp. But nothing is unbreakable and no motor lasts forever. Everything has a limit and in the world of racing when limits are being pushed expect anything...
Interesting stuff, maybe get a petition together along with these results and take them to nissan and have them make improved blocks as part of their legacy programme that they announced a while ago
Wow, I know very little about RB engines overall and this was fascinating. Really loved the actual technical exploration and explanation. Nice bit of info to have!
I think venturing off to other engine configurations would awesome. Vq’s, n54, 302, 4g63, k20c1, etc etc! Awesome channel thought keep up the good work!!!!!!
I'm a huge Nissan fan and that hurts. But the fact remains that block was only designed to handle 500 horsepower. Not sure if this is an engine you guys would have lying around but l28et can you guys measure that block. A lot of people say the n42 block (75-78 I think) is the best vs 280zx f54 block. Ive read all kinds of things on the internet like their siamesed bores and wondering if you guys can put it to rest if they're a good block or not.
@@gav240z any block can be like that. Especially if the factory that produced said series of block was known to not have a method of quickly cooling the cast
@@willemszchmilem7678 true, but so far all the blocks I've had tested come back different regardless of casting code. Friend of mine works with Les Collins Racing in Victoria and he said they go through 30 junk blocks before they find a good 1 to take to 89mm or so. I'd still be interested in testing, but feel the sample size may not represent the full story.

Great video, RRR owners will no doubt want a re-test with a different sonic tester, thickness tool and scales. Fact is the block was designed to make 500hp, keep engine cool, be lighter than standard for racing. Tick, Tick Tick. Nissan at the time only cared if it made it through the race and/or races for it's specified lifetime, once it cracks throw in another. They didn't design it for 1000hp plus full weight street cars, years of rev limiter bashing or for a turbo the size of your head strapped to the side pushing well over 30psi. If the remit was 1000hp plus out of the factory at 50psi boost it could've been done and it would probably handle 1500hp much like the current engines handle well more than the stock power and boost they were designed for. Money = Power, they landed where they landed.
don't know that's why i asked hahaha well considering in usa they get 1600hp out of em, there's a few here round 1000bhp so u gotta think it'd be similar strength? lol
@@5lcalais1 not necessarily. Show me that 1600hp one man need to inspect setup, in terms of what we have here unless they set the stock limiter to bounce more freely without cutting with as much force so as to not see rodney come out to play, builds with forged bits and bobs crank cams etc can't really be judged in the same category If I had to guess the hardness of a v6 eco motor would have varied a lot over the years not anything crazy but from 15 to 20 between weakest and a reasonable block to work with, then there could have been a few unicorns later on in production Who really knows man unless there was someone in the factory at time of the cast being formed because it really does vary eg supercooled cast etc

@@MotiveVideo makes sense fellas! Would love to donate my motor if it meant anything I'm about to boost it but would love to spread the word about these motors so others get around it and parts start to become more readily available :'D
I watched the Live stream and this one now. Great job guys. Just a side note. The comments regarding the block prices make perfect sense. But if you are a collector of rare parts you will always pay top dollar. Like the owner of this block, he never used it or opened it. who knows the plans for it. But obviously the results didn't matter. Collectible items will always be expensive and only worth the money to the collector. My poor opinion. Thanks for the Videos guys! this series is awesome
Guys, would you do a CRANKSHAFT comparison video of RB25/26/30 vs 1/2JZ???? It would be very interesting to see the material and all the journal diameters!?
thank you motive video as the block testing vids have really been good and it really shows what to look for when building a engine. I hope you keep it up and try and move into other parts
Is a rb vs ej block possible? Does sonic and hardness testing work in the Same way on the ej? I would like to see this. I love both engines but I would like to know which is better
I’m sure some buyers can still justify the price for owning one (rare part, restoring or replicating a Z-Tune, etc.) but it’s good to have light shed on this for the majority looking for a block to suit their purpose. That said, I am aware of a (former?) 1/4 mile Skyline world record holder from NZ using a GT block pushing 1,600whp. I guess with the inconsistency of their bores, there’s bound to be a few needles in the proverbial haystack. Fantastic test, by the way. Are the rumours of N1 and GT blocks having revised cooling channels to address cylinders 4-6 overheating during endurance applications true at the very least?
Thank you for sharing this video, but I wonder. We do know ultrasonic thickens measuring depends greatly on material type being measured and proper calibration of the instrument to specific material, and you did measure significant hardness difference between blocks, so how do we know GT block is not much more worse than what it appears to be form measurement you made to be quick, simple and digestive for wide audience. I did not see you re calibrated so I expect it should be some difference, since ti was so evident in hardness measurement that sound was so different even through video recording. For me this means Ultrasonic waves for thickness device also have significant change in speed of propagation what should change results. Just wondering, maybe you can comment?
Did you watch the video? We calibrated the sonic tester to suit the material of the GT500 block. We did it based on old settings and it read .15mm lower. Once calibrated, it was correct. Why do people always assume we dont do or know these things?
@@MotiveVideo Sorry m8, my bad, I missed it, since I skipped to testing part. My lady was screaming on me watching youtube "crap" so I rushed it a bit. Thanks for taking time to answer. I do appreciate it.
Hey guy love your content all different RB comparisons as well 2Jz What to ask you if you can compare the bmw s54 engine and if you can get your hands on the new Supra’s engine Would like to see how the German inline 6 engines compare to Japanese
Car TorX of it’s stripped cleaned and ready to go. Drop off to us and we will put it in the que Without funding support can’t guarantee when it gets done
Are you able to get one to them? Make sure it’s the 90+ block only. The one that was much more beefy and revised after Group A racing. You may know it has much beefier supports and bigger deeper main skirts webs.
@@georgehoneymen6045 I do have a 1990 Japanese import. It is at the engine builder right now. I don't know it my builder would like me if I go and take it from him at this time because of the delay it will give him, But will see.
Just a Honda guy hiding in the bushes watching the war between the RB and JZ guys. Edited: kinda disappointed with the RRR block its good for a 500hp street build.
Love your vids guys, any chance you guys will test or have tested the vg30?? Is it able to be compared to the RB/2j? Always been curious if it is actually a better block than the RB. Thanks heaps
@@MotiveVideo How do you know it wasn't due to wear (piston and ring friction)??. Did you measure the bore wall thickness, before and after, to make sure it was the same??. I thought block material was too brittle to deform like that. (and thats exactly what Hermann also said in the video).
Can you test NA 2JZ blocks (vvti, non-vvti, fse)? Because 2JZ-GTE is very expensive it's very common practice in Russia to build 1.5JZ with NA 2JZ block. I'm told that only differences are in oil system.
I dont really care tbh it hurts a bit but rbs and jzs are both cool and the diffrence of years between these when they were designed is quite large for the automotive world there were large improvemnts in materials, block requirments, casting techniques and chassis design etc
That’s it at the end of the day, the engines were designed for a purpose and they did it well, winning race after race in their day. Still making unbelievable power today. to say they are a bad block because it won’t last at 1000hp I can understand if you are building a competitive drag car, but still hugely impressive for its age.
most, if not all, factory street legal sportscar engines from the 90s produce 1K hp from factory. the point of the test was: were the RRR myths true or not and is it really worth paying the premium expecting a stronger block. answer seems to be No. that's it. no fanboy biased excuses from the tester.
Good vid guys. Dead set Andrew's voice overs at the end of his vids could sell me anything he sounds very trustworthy/professional.. well I guess that's why I have every dam motive DVD lol and still own a rb 🤘 and herman makes me wanna send him my rb25 neo to be tested and built
Why I am not surprised? And the block was made for 500 BHP and to be 2 kilos lighter, not to handle more power... At least the skyline gtrs have traction...😁

Hey have you considered testing rd28 block it’s a diesel block but I think you can you use in petrol application
You must be a late subscriber to our channel. We already did it December last year
I watched the Live stream and this one now. Great job guys.
Just a side note. The comments regarding the block prices make perfect sense. But if you are a collector of rare parts you will always pay top dollar. Like the owner of this block, he never used it or opened it. who knows the plans for it. But obviously the results didn't matter. Collectible items will always be expensive and only worth the money to the collector.
My poor opinion.
Thanks for the Videos guys! this series is awesome
Have you guys ever done tests on a VG series or L inline 6's series?
Guys, would you do a CRANKSHAFT comparison video of RB25/26/30 vs 1/2JZ????
It would be very interesting to see the material and all the journal diameters!?
thank you motive video as the block testing vids have really been good and it really shows what to look for when building a engine. I hope you keep it up and try and move into other parts
Is a rb vs ej block possible? Does sonic and hardness testing work in the Same way on the ej? I would like to see this. I love both engines but I would like to know which is better
noob question. But do people ever put sleeves in iron blocks? If so, what would be the reason behind doing so?
Sounds like the use of the likes of darton wet sleeves might be the go for serious rb motors
Can you do a rd2.8 block?!?!??!??
I wonder if this will turn into a bit of a series testing other engines and busting myths.
The best thing about the rb block will always be the cover for the water pump
I gust want a billet block withe water journals and what’s the hardness difference between a billet and iron
I’m sure some buyers can still justify the price for owning one (rare part, restoring or replicating a Z-Tune, etc.) but it’s good to have light shed on this for the majority looking for a block to suit their purpose.
That said, I am aware of a (former?) 1/4 mile Skyline world record holder from NZ using a GT block pushing 1,600whp. I guess with the inconsistency of their bores, there’s bound to be a few needles in the proverbial haystack.
Fantastic test, by the way. Are the rumours of N1 and GT blocks having revised cooling channels to address cylinders 4-6 overheating during endurance applications true at the very least?
Great video's Motive, thanks for all your hard work!
Is the measuring in inch or millimetre? What are mills? I from the Netherlands and we measure in millimetre. Thanks
Thank you for sharing this video, but I wonder. We do know ultrasonic thickens measuring depends greatly on material type being measured and proper calibration of the instrument to specific material, and you did measure significant hardness difference between blocks, so how do we know GT block is not much more worse than what it appears to be form measurement you made to be quick, simple and digestive for wide audience. I did not see you re calibrated so I expect it should be some difference, since ti was so evident in hardness measurement that sound was so different even through video recording. For me this means Ultrasonic waves for thickness device also have significant change in speed of propagation what should change results. Just wondering, maybe you can comment?
Did you watch the video? We calibrated the sonic tester to suit the material of the GT500 block. We did it based on old settings and it read .15mm lower. Once calibrated, it was correct. Why do people always assume we dont do or know these things?
@@MotiveVideo Sorry m8, my bad, I missed it, since I skipped to testing part. My lady was screaming on me watching youtube "crap" so I rushed it a bit. Thanks for taking time to answer. I do appreciate it.
Please feature the Nissan FJ20, Mitsubishi 4G63 and Toyota 4A-GE , that will be amazing !
Herman is going to use a RB25 for his build, will it be bored to 2.6 or keep it 2.5 so the bore is thicker and stronger ?
Hey guy love your content all different RB comparisons as well 2Jz
What to ask you if you can compare the bmw s54 engine and if you can get your hands on the new Supra’s engine
Would like to see how the German inline 6 engines compare to Japanese
Just out of curiosity, considering these things are worth serious money, what are the odds of a counterfeit N1 block?
Get this man to 100k subs.
I have a 7M GTE block please please test as well. Bust our myth. Great show guys
Car TorX of it’s stripped cleaned and ready to go. Drop off to us and we will put it in the que
Without funding support can’t guarantee when it gets done
Are you able to get one to them? Make sure it’s the 90+ block only. The one that was much more beefy and revised after Group A racing. You may know it has much beefier supports and bigger deeper main skirts webs.
@@georgehoneymen6045 I do have a 1990 Japanese import. It is at the engine builder right now. I don't know it my builder would like me if I go and take it from him at this time because of the delay it will give him, But will see.
@@MotiveVideo where is you shop I might try having it delivered. I myself live in Melbourne.
@@cartorx1261 Man it would be awesome but I understand if can't!
Keep these vids coming, love them
Just a Honda guy hiding in the bushes watching the war between the RB and JZ guys.
Edited: kinda disappointed with the RRR block its good for a 500hp street build.
Love your vids guys, any chance you guys will test or have tested the vg30?? Is it able to be compared to the RB/2j? Always been curious if it is actually a better block than the RB. Thanks heaps
Nissaids living up to the name.
Can you test a billet RB block just to see the difference??
Still no m50b25 block video?
"Ballooning" of bores is due to abrasion (wear due to friction)... not deformation (yielding). No?
nope. Cylinder pressure literally can push bores out of round in different directions. Happend to our GT-R
@@MotiveVideo How do you know it wasn't due to wear (piston and ring friction)??. Did you measure the bore wall thickness, before and after, to make sure it was the same??. I thought block material was too brittle to deform like that. (and thats exactly what Hermann also said in the video).
Are RRR gt500 sleeved then?
Can you test NA 2JZ blocks (vvti, non-vvti, fse)? Because 2JZ-GTE is very expensive it's very common practice in Russia to build 1.5JZ with NA 2JZ block. I'm told that only differences are in oil system.
Block and crank are the same. GTE has oil squirters and different pistons/rods. That's about it.
Correct me if am wrong but can u put sleeves in d bores ?
I dont really care tbh it hurts a bit but rbs and jzs are both cool and the diffrence of years between these when they were designed is quite large for the automotive world there were large improvemnts in materials, block requirments, casting techniques and chassis design etc
Excellent work as per usual guys ☺
Hey guys where is the motive workshop located???
You guys need to test the 2jz-ge vs 2jz-gte
What about 7mgte block compared to 1jz? Just curious how 7m stands up against jz's
Compare one of the BMW blocks - m54 , m52 , s54 thanks
That’s it at the end of the day, the engines were designed for a purpose and they did it well, winning race after race in their day.
Still making unbelievable power today.
to say they are a bad block because it won’t last at 1000hp I can understand if you are building a competitive drag car, but still hugely impressive for its age.
most, if not all, factory street legal sportscar engines from the 90s produce 1K hp from factory. the point of the test was: were the RRR myths true or not and is it really worth paying the premium expecting a stronger block.
answer seems to be No. that's it. no fanboy biased excuses from the tester.
As I've mentioned before, just for comparison do some old school blocks, I suggest the old Jaguar XK 3.4.
Good vid guys. Dead set Andrew's voice overs at the end of his vids could sell me anything he sounds very trustworthy/professional.. well I guess that's why I have every dam motive DVD lol and still own a rb 🤘 and herman makes me wanna send him my rb25 neo to be tested and built
can you sleeve cast iron block?
Compare a sr20 vs a 7a block?
Why I am not surprised? And the block was made for 500 BHP and to be 2 kilos lighter, not to handle more power...
At least the skyline gtrs have traction...😁
So... a GT500 RRR block is good for 500hp if you want to actually keep it. Noted.
Should find a 1920s or 1930s engine block and strength test that
Any plans to do this with the popular 4's ie 4age/3sgte/Sr20/4g63/k20 ?
Jim Craig
Please?!?
Can you do bore testing on the 2JZ?
Its been done. Look at the other videos in the series
So is it possible to sleeve the bores and would it be worth it?
StickProductions2121 might as well sleeve a $300 block then
