I was lucky enough to meet the electrical engineer steve curtius who worked for Gibson during those days. An extremely clever guy who's contribution was key. One engine test was a 44 gallon drum with another choking throttle to simulate the elevation changes at bathurst They were running the turbochargers 2000 rpm under their centrifugal burst speed too. The kind of guy you dont forget ✔
Would love to see the RRR GT cut up but never will happen. During a visit at Omori Factory there was discussions with one of the engineers who was either unwilling/didnt know to answer the question of what made the RRR stronger than the 05U/24U. The simple answer was: "If we didn't need it, we wouldn't have made it"
Heaps of people have had the same experience over the years, which is funny when you watch the previous Motive video claiming there's no advantage of them..
@@JH-jo9wt yea for sure. From memory they were ~$10kAUD years ago (at the time when N1 blocks were about $2.5k).. Nissan/Nismo didn't just stamp a different number on a normal block and send them out
@@slow26gtr im thinking a different material, the o5u looks different to the N1 which looks a little bit different to the RRR material wise at least in surface finish. RRR block also did the 24h Nurburgring. Plus probably even more reinforcement we cant see
@@JH-jo9wt even the old vs. new N1 blocks have had revisions based on the outter surface finish.. but yea would be cool to see a RRR block get cut up too, just out of curiosity more than anything
Cool and thanks for sharing this info for us...Also just wonder is that some extra material, i mean some engine block filler in 1:42 in that water jacket??
Crap. I’m putting a Nitto 2.8 kit into an 05U block. Using a PRP block brace. Looking for 800-1000whp. Any suggestions? Grout? I guess we’ll see how it goes!
Herman. This might be a stupid question but can u run sleeves like darting sleeves in an rb block and if yes. Would it be an improvment , What is the process .thanks bro love the vids.
So the bore is the weakest point. I have a rb25det series 2 I would like to make 600rwhp with. What are the necessary upgrades, I understand needs forged internals (preferably nitto) as well as an upgraded oil pump once again nitto. What else is a block brace necessary? From what I’ve researched seems to be more for awd applications due to the increased torque on the block from the front diff/awd. What can be done to strengthen the bore since last episode sleeving isn’t a good idea for rbs (or only ones which have been cracked)? Would be interesting to me if motive went into detail about budget building but spending money where it’s worth it to make 600rwhp and up in stages 800 and so forth.
Also 2j and ls is out of the question I don’t really like conversions because they never really work as well as a factory setup imo from the ones I’ve seen. Also I like to play life on hard mode, and rbs seem to be the right engine for that.
@Uncle Putes No there's a difference between reality, and fantasy! It's quite disrespectful, and just arrogant of an Aussie to think that they "improved" on a Japanese built machine block. Yes they modified a block for more power but UNDER THE SUPERVISION, and blessing of Nissan.
@@mrman8856 Yet the Aussie GTRs made more power than their Japanese counterparts, oh how disrespectful. I think you're the one living some strange fantasy mate.
Well shit what does the RRR have over a 24u then? Or would Herman need some poor bastard to donate a RRR block to be spliced? Which aint going to happen any time soon unless someone has split a RRR that anyone knows of
Yes he talked shit left right and centre to sell his braces was telling everyone the N1 block is no better including me on the phone, I asked which cracks less around the oil feed hole in online discussion and he messages me immediately telling me please not to ask that question publicly total fuck head
is the N1 block better? “Yes and No” this guy serious? why not just say yes? this did has yes fever man! Forget what you say-for 20 years the n1 has seen 1000kw over and over the oem block doesn’t like HALF THAT! this is one of those blokes that has all the tools but not the toys!

As a Nissan fan, still looking for a book on Gibson Motorsport, their contribution is insane.

Apparently if you look at the videos from motive there is almost no difference to the RRR block
@@MrSpartan117fan I'm aware, but NISMO didnt just restamp blocks and put them in the racecars and all the top customer cars
Thank you so much for clearing this up. This is exactly my experience with two cracked 05U blocks and a solid N1 block that never cracked.

I love watching Herman talk about all things RB. He’s a natural in front of the camera & is a virtual encyclopaedia of knowledge.
Wow, that's cool to hear the feedback from the AUS race teams helped develop the N1 block.
So glad I bought a Nur spec 2 N1 block decade and a half ago 🤘🏼. Thank you for the wicked new Herman. Love you man.
Love these tech videos Andrew, please keep them in the line-up
I love the attention to detail, destructive analyzing reveals the truths. There are other manufacturers blocks I would also love to cut apart.
The oil returns are so miniature. Guess I’m just used to the 3S and JZ massive oil returns.
Block twisting aside, if the limiting factor is the bore and cylinder pressure, does this call into question the effectiveness of a block brace?
Block brace stops the mains walking, that’s the RB’s biggest issue.
Oil pressure drops at peak torque..
Thank you:
Herman & PRP

Cool and thanks for sharing this info for us...Also just wonder is that some extra material, i mean some engine block filler in 1:42 in that water jacket??
Fantastic detail Herman. Great watch
Interesting info. I wonder if there is a difference if we cut a GT500 RRR block and compare to the 05U block and N1 block.
this!!
So extra material but yet they weigh the same, did they take something else out somewhere or use slightly different materials to achieve that?
Interesting point. I noticed that as well
My guess its probably not enough material to change the weight of the block much, maybe half a Kg
What are you talking about? The n1 is way more heavy
@@codakanjo6690 In the vid it was listed as the same weight as the original blocks, that's where he's getting his info from. Didn't you notice?
That's some pretty cool history about the Gibson crew.
Really informative vid, Herman. Thank you and thanks Motive
Crap. I’m putting a Nitto 2.8 kit into an 05U block. Using a PRP block brace. Looking for 800-1000whp. Any suggestions? Grout? I guess we’ll see how it goes!
Half block fill and billet braces
Herman. This might be a stupid question but can u run sleeves like darting sleeves in an rb block and if yes. Would it be an improvment , What is the process .thanks bro love the vids.
What about the GT block? Anyone know what the improvements were?
what about the rb30 block compared to the N1 block ?
I know, the only real hole in that tech vid unfortunately
The Rb30 blocks are harder and generally have thicker and more consistent bores.
What about grain structures? Do you think the structure will affect the strength?
I would really love to learn about the RB25 Neo 6 Thanks
1000th like. Why is this channel so underrated?
I love this nerdy shite
Awesome video guys
But I still love my rb20 r32 gtst
What do you think about NEW 05U block ? He is stronger? This is new block and new materials used. Thanks !
got any links?
rb30 block have the same features as non n1? what about rd28?
So the prp brace is useless on a N1 afterall i would be spewing if i went to the expense of installing a brace after this
So what cylinder pressures are cracking bores?
This video has made me a chunk of money 💰 😂 thanks guys.
what power can a n1 hold??
what about the 23U block?
how is it different from a standard 05U?
Nice!!
Are these things considered when making the billet RBs?
billet rb is a blank sheet. almost completely different
No, they keep all the inherent weaknesses when they design the billet blocks 🤷♂
Real shame the Australian developed GTR didn't race against the Japanese ones
They wanted to. Nismo said no
@@MotiveVideo I detect some saltiness from Nismo.
25 neo 4wd block is probably the same as the 05U block?
So the bore is the weakest point. I have a rb25det series 2 I would like to make 600rwhp with.
What are the necessary upgrades, I understand needs forged internals (preferably nitto) as well as an upgraded oil pump once again nitto. What else is a block brace necessary?

Also I like to play life on hard mode, and rbs seem to be the right engine for that.
Big ask for a comments section bro 😂 Would suggest you start a thread in an appropriate forum
Ls swap
Nikasil coated steel liners
Great info!
So the N1 block is an Australian developed rb26 block?
Inspired
Let an Australian tell you they invented Skykines 🤣🤣😐
@@mrman8856 There's a huge difference between inventing and improving...

Is an RB30 stronger than an RB26?
Yes but not by a massive amount
Billet RB30 is the strongest block by a mile. There the ones you see in the 2000plus hp builds.
@@Dacommenta I know that. My question was about the cast RB30
Rb30 and RB20 are the strongest mass produced blocks.
@@Nightmaretyrant RB20 😂 someone owns a 32 GTT
Sheeeeesh
2JZ THE WORLD!!!
Ok, now carve up an RRR block and tell us what makes it better than both of these 😆
Well shit what does the RRR have over a 24u then?
Or would Herman need some poor bastard to donate a RRR block to be spliced?
Which aint going to happen any time soon unless someone has split a RRR that anyone knows of
The PRP block going to be CGI?
This guy you where saying the opposite not too long ago!
He said they can’t find anything better in the base tests. There must be something inside
Exactly what I thought too.
Yes he talked shit left right and centre to sell his braces was telling everyone the N1 block is no better including me on the phone, I asked which cracks less around the oil feed hole in online discussion and he messages me immediately telling me please not to ask that question publicly total fuck head
TH-cam is coked, unless Iw atched this while asleepw itht eh computer and youtube on, it said Ia lready watched mate no way
You ok mate?
is the N1 block better? “Yes and No”
this guy serious? why not just say yes?
this did has yes fever man!
Forget what you say-for 20 years the n1 has seen 1000kw over and over the oem block doesn’t like HALF THAT!
this is one of those blokes that has all the tools but not the toys!
Rb blocks are junk. There are better engine’s nowadays. 200 dollar Barra block is a start lol.
the Barra is the same hardness as an rb26 and suffers from cracking both in the bores and block too.
cool, no one here cares lol
