RB25DET vs 1JZ-GTE - Engine Block Tests and Comparison
Вставка

- We did RB30 vs 2JZ engine block comparison, now its time to test and compare their little brothers. The RB25DET and the 1JZ-GTE engine blocks.
Please note, we are only testing the bare block, no other ancillary parts that go with it. - Авто та транспорт
So much more respect for the Supra’s 1J/2JZ engine after watching these videos. They engineered the crap out of these engines, no wonder they’re so legendary.
yeah I am practically a fanboy of the JZ engines, but even I never realized how overengineered and well made these engines are. I knew they were good, but I didn't think they were *THIS* good, it absolutely blows my mind.

As an RB lover the stats break my heart 🤣
But we can't do anything about it... Uguu...
RB is the caterpillar
mate youre everywhere!
1JZ GTS...
If you want them to test a block.... strip one down and send it in🤣
The 1JZ is 11 KG LIGHTER! With thicker bores too.
Yeah that's nuts.. Better quality steel I wonder?
@@mattfowles7239 Steel may be the same alloy. It's the control of the casting process that matters. The rapidity of the cooling rate of the block casting effects tensile strength. Faster cooling the better.
@@tumdeax You don't want faster cooling of a big casting, that introduces alot of inner stress that cab crack or change dimesions after machining.
Iron my dudes, it's iron. Not steel. Iron is porous, which means it retains oil nicely and stays lubricated. It's why it's good for blocks.
Can you guys do some 4 cylinder comparisons too like the 4G63 block Vs the 4B11 block or the SR block Vs the 3S-GTE etc? I've got an Evo 5 so would be great to see some testing done on the 4G63 block
Ej20 and ej25 have mixed reputations too. Probably been tested a hundred times before but I like the way these videos are presented
@@HaydenSupaTeeu cant compare a iron block to a alloy block, the only difference between ej20 and ej25 is the bore size and thickness and I can tell u the ej20 wins hands down
Scaniaman93 patience. We can only make so many videos in our spare time as we can
If we had a million subscribers we could make UA-cam videos every day
If you build it, they will come :)@@MotiveVideo
@@HaydenSupaTee why bother john cena 😂😂. Im such your a wrestler. You troll . Ej20 and sr20 are both rubbish
It’s not just the blocks that make JZ king. They oil pumps are superior, the stock head gasket is damn near perfect, the heads are awesome un ported. List goes on
And the People that go 1.5jz... like them also.
thank you yamaha ;)
Dan MC we are looking at doing other comparisons later
We Kew it simple by just looking at one component at a time
@Lucky Rooster have to wait for that video
@@MotiveVideo People say the head on 2JZ-GE is designed better and has a better flow. There are many that go GE+Turbo instead of GTE
would love to see the m50b25 comparison . its a well capable platform
+1
Meh, I'd say it's average at best. Still, I'd like to see it aswell. Mainly because literally every BMW guy here in Sweden says it's an amazing engine.
Euro block S50 too
@@theXbaT1 yeah Euro S50's are extremely reliable at high power, but they are so damn expensive to buy and build that no mortal man could afford it
@@TheProtagonistGabber
what on earth? s50 cost somethink like 2000-6000€. that is not that expensive. at least here in germany. on the other hand we definitly do not have a shortage on bmw blocks. they are fairly good. the real weakness are the connection rod bearings. you have to change those every 100k km. otherwise my e36 works perfectly fine, despite having 380bhp (airbox, cams, ecu).
Love my 1JZ 😍
Ditto bro. 👍
your production quality and information delivered have had a huge increase over the past year. and you collabs with nitto and PRP have deffinately helped with that. great job Motive!
I can't see enough of these - so interesting! Looking forward to seeing so many more of them with different engines...
You guys are awesome with these Platinum Tech engine nit-picking series. No one else in the world does it
3S-GTE Gen 2/3 VS SR20 would’ve been very interesting too. :)
Love these videos Andrew. Very interesting and informative.
Leave following these tech series. This is phenomenal. Thank you Andrew and crew. I'd like to request an answer to one of the biggest questions of today.....2JZ/1JZ vs B58 (BMW)...Hoping you can pull this test off in the near future.
1jz engine values will now skyrocket
Debt and Regret your good at telling the future check the prices now lol
Just got mine today! With an R154!
I remember seeing this comment last year now their worth a million 😂
They actually did lol
a year later and they have....
Im loving these series of videos. Its all facts and no bs.
Thanks for the video and the objective numbers! One correction: the video says deck height, but I think deck thickness is meant. The deck height is the distance between the crank centerline and the top of the deck, essentially the block height. This is the main difference between a 1JZ block and a 2JZ block: the 2JZ block is the taller of the two.
Thank you again guys. Would be good to see the merc engine m157 being analysed like this
You need more subscribers Andrew. This channel is 20 times betters then half the american car channels going.
Nathan Lenehan thanks mate. We’re trying and putting more effort in now
@@MotiveVideo well its appreciated..by the Australian audience at least. Would actually been very keen on meeting you one day.
Absolutely love these videos! Keep em coming
I’m glad I went with the 1jz in my r33 now thanks for the info been really enjoying the content
I've just gone 1jz gte vvti in my s15 over an rb
Yeh I went non vvti, did the same conversion in a mates s14 and it went well so I decided to do the same
Rb25 ten times better
@@kartaku132 did you just ignore the video while commenting this?
Oh damn... When you guys can get your hands on a B58 block you have to do another comparison! New Supra block vs old Supra block. Would blow up. Plus I'd love to see the information.
Thanks for this you guys, much appreciated.
Doing straight sixes might as well throw an N54 and N55 in there too :D
Loving this series, good to see the data
I would like to see the german S54 just out of curiosity.
you and me both
its alu so no go
TheXbaT no it ain't
Mercedes m104/103 om603/606?
@yba202 I didn't even know they were from australia this was the first video I saw
Great series, Herman knows his stuff.
Herman rules as usual, great video!
Almost at 100k keep them vids coming
Thanks for the comparison. Love my JZX100.
these are great, thank you for doing these videos
Been waiting for this match up! 👍
Great video again guys. The 1JZ was designed by Yamaha for Toyota, as a replacement/upgrade to the M series Toyota six cylinder engines. The 7m gte which came in the JZA70 Supra was a great engine but suffered from overheating, head gasket and head stud issues where the head would tend to lift at high boost. As a die hard RB man, these videos are heartbreaking, but give credit where it's due, the JZ engines are monsters.
Yamaha only designed the 1jz head, not the block.
I´d like to see you explain what exactly you´re measuring, especially the hardness test, to me they´re just random numbers, the higher the better. Really interesting channel by the way, I´ve never seen anything like this, great work.
Id love to see the comparisons with the heads, flow tests etc
Also be interested to see the BMW N55 platform seeing as it's basically a comparative block.
Would love to see an in depth video like this between the 1FZ-FE vs TB48!
These vids are really interesting, thanks ;)
This channel is going places !! I love you guys already ! Keep it up
Great video, straight to the point no bs
Seriously loving this stuff mate. Let's an old bloke know what he always suspected. 👍
I agree this channel is underrated. Every time I say to some one if they follow motive DVD and they seem clueless ! Spread the word 👌
K20 vs SR20
K20 vs 4G63?
k20 all the way. the sr20 is a very average 4 cylinder turbo motor.
K20 vs 2zz lol
Lucky Rooster what you got something to say 😂😂
Are you serious? K20s on a whole other level. SR's are nothing without its turbo. The DC5 type R is faster than Silvia's despite them being turbo.
this is like Sword vs Katana nice video i hope all the 1jz are good
Makes me happy I just bought a chaser 1jz gte
Nice review
"the internet has spoken". Oh well, it still speaks,....RB20!
Tom Ingvaldsen that has been filmed. We can only edit in our personal time so quickly
@@MotiveVideo Oh,....thats great👌 Thanks for these interesting and enlightening vids👍
Loving the vids guys great work. I would be interested to see how the 7mgte stacks up against the 2jz or rb30.
It doesn't, 7ms are an amazing boat anchor. 2jz is the younger stronger brother. Anyone who's built a 7m will tell you the dramas they've gone thru just to make them stay together.
@@TARMACULA these guys are testing the castings, im curious how 7m castings compare simple as that. 7ms are old tech so they have their quirks especially the early long blocks but i have been running a 400whp 7m for about 7 years no issues with little money spent. Im getting tired of proveing 7ms to dense internet people.
What about d RB20det and the RB24 carbrueted block ? ... those RB24 consist of d rb20 stroke and rb25 bore
To be honest, I would be more happy meeting these guys for example Herman than any other celebrities.🙌🏼
1JZ could be the most underrated 6 of all time !
No m104.
7mgte bruh
@@chrisjay7736 Oh hell yeah. Love to see another Benz-knower
They're hardly underrated, they're idolised!
Barra
Wow!! Wasn't expecting that! That Supra engine! Is no Joke!
Thanks for this @motivevideo seeing Herman reactions was too funny
As some people have already requested, I am sure at least your European and some American viewers will be highly interested in a comparison with the BMW M50 block. It is 84mm bore, 48kg and has 10mm head bolts, that is all I know after a quick search but how is the rest of the engine? Here in Europe we have those engines in tuner cars, drag cars, professional drift cars, sometimes you see a M50 turbo powered Nissan Silvia... Thanks!
Hardnesses will be different in different areas of the casting. Thicker parts are usually softer.
Would love to see the numbers from the "baby RB", CA18DET
Would love an ej vs 4G comparison even though they are very different in design, materials, etc. still would be awesome.
im a boilermaker with abit of age,and spent a lot of time in bhp.the meteorologist there new there stuff and was always cutting different car brands castings up,toyota was always good back then.im guessing herman knows exactly what im saying in metal count and grey power metal counts and acid tests and so on,there are still afew of the old boys around be good to get 1 on your show and get him to explain why things can be stronger but lighter and so on,from memory I think a yank did a lot of Toyotas early metal count mixs.be good vid for those that don't know.
Can an alloy block comparo be done? vq25det, ls1, sr20det, 5.0 coyote as a suggestion? Dont know what mitsi or toyota blocks are alloy but throw some in the mix as well.
Another quality Vid
Wonder if Yamaha also building pianos has anything to do with it? The attention to detail and finer points, same work ethos in their mechanical division?
Keen to see the rb rrr block
Would be an awesome comparison against the 2jz.
Saw one for sale about 3 years ago. Starting bid was 10k. Sold within that day without disclosure of the sale price. Havent seen a geunuine one since then. Dont think anyone would sell one now considering GTR tax atm. 250k for a stock nur spec dayummm
Interesting to see how the German versions of these fare in this test, the M50/52 and M104, both respond well to boost as well!
Mercedes M104 is an awesome inline 6 capable of over 1200hp on stock pistons acces to 3.6 liter diesel crank and super cheap.
I wonder if there is one for LS and LSX block since they say it can hold a lot... can we have a those block interviewed too???
Do some aluminum block tests if possible. Like later model BMW engines, or maybe Volvo modulars.
So is it safe to say that a JZ can be remapped to rev higher than an RB more safely (with the proper mods)?
Also, the 2JZ is even slightly lighter than the 1JZ.... that's crazy!
All the stats will never beat that RB note....
PLEASE do a comparison between RB25, 1JZ, and the BMW M50B25!
I would love to see you guys test a 7M-GTE out of a MK3 Supra. It's not as good as the JZs but I would love to see how the more common supra engine compares to the RB blocks
@@jzxtrd337 oh ok, but what about the 1g-gte?
would there be any difference between std rb25 and rb25 neo?
You should do a video of rb cylinder head vs jz cylinder head. Valve angle, sizes, materials etc... I think it would be very interesting and educational.
Can you please do a rb25 vs rb25 neo comparison as theres a lot of myths and guessing on the forums. We like to understand the difference in internals and heads and what it does to power with the same mods
I knew that putting the 1JZGTE in the MK3 Supra was going to be Paramount. Again legendary in its own right!!!!
Question. Whilst this series is very interesting, does all of this data basically not matter unless you are aiming for high to ridiculously high power figures? ie 1000hp and up?
It reflects on the rest of the build quality
@@alexlittle2224 ?
tell us where the extra weight of the rb is at... how did they get a heavier block weaker?
Pls test the n54 bmw block ....
Could you do a whole video talking about thickness and hardness? By that of course I mean in terms of engine blocks! would be great if you would go more in depth about the tools you are using and what exactly the measurements mean. I would like to understand the values better from a technical perspective. I'm sure many other viewers would as well!
Awesome videos and thank you.
Wonder how an sr compares to all the blocks. Really enjoy these vids tho! Thanks
Not well as they aren't cast iron
I mean true but bare sr blocks can handle a suprising amount of power
Would love to see a VG30DETT vs. the RBs and JZs.
yeah that'd be interesting. Or even the VQ
I'd like to see a VW 06A and EA888 since they're made of iron too. Some VR6s to compare against the Japanese engineering would be fun to see.
completely impractical i know but id love to see a 7mgte and how that stacks up to other RB's and JZ's. Supposedly the bottom ends were quiet good.
The choice between a 25 and 1J is easy for me, if I've got a Nissan, I'd use a 25, if I've got a Toyota, a 1J, I've seen 25s slightly out perform 1Js with the same sort of setups in street cars, 1J needed a bit more boost, once again both awesome motors
what about the rb26dett vs the vg30dett
👍 facts rule
kill all myths .
Without headflow numbers all of this means nothing sure the block can support 1000hp but can the ports flow around the 333cfm required to make that power
carbonfiber492 that’s not part of this test but based on what we’ve seen them do on the dyno and track, both van make grunt
Do you find any harness differences with the age of the blocks/kms traveled i.e. from the same year a block done 50k vs one done 300k?
Mike Jovi with RB? Not really? We have one sitting outside rusting we test every 6 months and no different yet
@@MotiveVideo ah testing the old cosworth logic.. but are you peeing on it is the important question?😂
Hmm I found that video very interesting. I understand the rb25 block is heavier than the 2j but fully built isn't the rb25 engine still considered lighter than the 1jz? Thank you for the video!
Should do one on a 3sge- 3sgte block vs 5sfe block.
What about a BMW n54/n55 compared to the other 6 cylinder blocks?
Finally a 1J and RB25
curious to see how the old dunnydore mang mangs compare, 5ls, ls, boss 260, windsors etc purely out of curiosity lol
If it were ever possible to compare k20c1 from the type r that would awesome. With a 4b11 or 4g63 or to ej20/25 or sr20
RB30 Stroke is 85mm hence 2962.5cc where as the the 2J is 86mm - 2997.3cc
It would be interesting if you could also do the RB20DET block just to see what you find.
Michael Barnett already have
Just can’t edit and release 10 videos in a day
@@MotiveVideo Fair enough mate, more than happy to wait. Just stoked you didn't leave the RB20 out. Very interesting series.
These tests are going to convert Herman to the JZ life.
Get that bmw m50 iron block to the test! Its propably not nearly as good as these but id love to see how it goes since its a common engine for turbo projects in my country.
How to up bore oil feed RB from 11mm to oversized?
Im a bit paranoid about the oiling issues with my RB25 and RB26 can anyone point me in the direction of a thorough guide on how to modify to make sure there is never an oiling problem?
Are the heads on the rb engines much better then? These videos seem like a pattern. The jzs seem to be much better at reliability, so much that for me, it might justify not using a rb at all
Basomga I don’t think so, it definitely seems like the 2JZ head is also much better than the RB26
this is cool and all, but since you do so many test of race proven 6 cylinders, can you test a race proven K series 4 cylinder honda engine? I wanna see it's hardness and thickness of bores. Thank you. K series being some of the most utilized and best 4 cylinder engines readily available, much like the barra in Australia.
Ran Dom send us one stripped, cleaned and ready to go
