@Platinumracingproducts have been working on a Rb26 cast block for a while now, and the first full size prototypes have come out of the mould, so we thought we would give everyone an update on progress. With new blocks from Nissan essentially non-existent, this will not only allow for a new block, but one that is far superior in strength and oil flow.

Im literally holding out my rebuild coz of this
Same I was gonna buy an rb26 to swap into my 300zx but imma wait until this release so I don't deal with the RB issues 😂
@@920.streetstyle 😂so true 👍
Nah you got no money for a rebuild otherwise you would of already
@@notbahhhdgoodsize5793 sometimes its good to wait. PRP products have literally never let me or my friends down.For some of us this is merely a hobby/ passion. Patience and humility is the only way you can defeat the devil ✝️. Im merely waiting for the good stuff.
@@notbahhhdgoodsize5793 thank you i cant afford this product. May you have a blessed and prosperous day. Im just kindly asking if you can google dangote. Cheers 🍻.
Excited to see you guys cut this and test the hardness and thickness and compare it to OEM and other blocks.
Looking forward to it 👌
I really like the no bullshit honest attitude from PRP. This is a massive challenge and im hoping you get there bud.
From just making small parts to improve the engine to remaking the whole block and head.
You guys are doing what Nissan Japan couldn't for the RB!!
Super proud of you guys from PRP & Motive Video, keep the RB innovations going 👏🙏🇦🇺
Agree! The Aussies are really taking this to the next level. I have a r33 gtst so not a lot of innovation or parts for my girl but if I get chance financially to ever get a GTR....... whooooo =)
Awesome. I would recommend a chat with legend pattern maker Peter White dolman pattern making . He used to have the Leyland p76 patterns all carved in wood in his ws . These are now on display at the Gilbert motor museum in Strathalbyn . Peter has made patterns for a huge list of industries. Including ROH , VN and corolla side mirrors you all know. And many more. Worth the chat. But full credit to Australian automotive engineering keep it up.
Yeah that's a good idea. But here aren't we discussing replicating someone else's engine blocks and heads?
@@racecrashrepeat nah it’s a new design that fixes all of the high horsepower RB issues. Ref earlier vid
Definitely gotta call this the Bathurst block or something. The 24U is the N1 and the RRR is the GT500. This is absolutely awesome
This is incredible, can't wait to see what this brings to the RB world
Reliable blocks 🤷♂️
I'm so pumped for the future! Great job PRP and all those involved. My next RB car in the works will have a prp bay basically top to bottom left to right! Keep it up!
LOL my r33 gtst is in paint right now, if you need someone to test the block........ lol. :) These are gorgeous. Out of my price range but just a piece of art! Good luck guys!
Bloody legend Herman! RBs will live forever!!
Keeping RB’s alive! Can’t wait to build my very first one day.
Good on you guys at PRP, doing amazing work!
My gateway back to RB life. On my bucket list
I need a RB in my life . If you can cast a cheaper skyline that would be handy
Also I will be sure to buy more products from you guys to help finance this as I build my car.
im proud to see how far you all have gotten, i'm hoping for the best with the final product
Awesome job Herman!! You have my support from Japan! Nice vid Andrew 👍🏾
Super exciting! More than likely going this route down the road on my r32.
This is the video I have been waiting to see. Thanks for sharing this one Andrew!🔥
Not my style of engine but it is great to see the effort you're putting into what you love
This is amazing! Well done guys
Amazing work PRP! The best in the industry still use cast (often ally) for their block! I’m talking F1, rally cross, Le Mans. Yes billet has its place, but casting is the ultimate.
Well done PRP and Herman especially! Mad!
World leading
Absolutely incredible
Doing gods work lads, Keep it up!!!
That is so awesome.
Can’t wait to see the testing videos and how much power people are going to make with these!
Roll racing and drag cars are going to be insanely fast with these because of the extra power!
Well done Herman and PRP
Very cool. Good to see aftermarket companies doing this kind of thing.
Prp need to do a cut away from the new casting and the old blocks and have them side by side to show the how big of a change there is
So exciting! 🎉
This is why I’m buying from PRP! Giving the market what it wants!
ill never be able to afford this but glad its being done. cant wait to see a full prp cast engine ripping.
Your statement (never afford) is only true because you believe it.
I reckon you're going to sell a shit tonne of these and the new r0 r1 heads.
Convinced my buddy to buy a set of prp cam gears instead of HKS for his Rb if he wants that r0 head sooner it worked
Herman,
HKS have introduced Pre-Chamber (TJI) onto a std 05U head couple years ago (Heritage program) claiming 600hp 5L/100km on a hks 2.8l 8.7:1 CR
On SAU someone has claimed its a non std head that HKS have cast, just to install TJI for marketing purposes
Others claim its a simple bolt on M12 retrofit on a std 05u head, no secret HKS castings
Will we see TJI in an RB one day given its massive adv for eg f1 1600cc 19:1CR 55psi 35:1AFR 850+bhp and the engineers say TJI plays a MASSIVE role in this by reducing knock, consistent accurate flame propagation & cobustion process etc etc
Or is GTSboy on SAU right and TJI it never going to happen on HKS's secret cast rb26 head they done for marketing purposes?
Yes id like to know too
Pre chamber means no knock big boost high comp on shit fuel -win win win win
First off, No.
Pre chambers help in cruise mode where in the pre chamber an a/f ratio can be reached that will burn (typically 14.7:1 - Stoic) yet the overall combustion chamber a/f is very lean. (+24-1) This system is used on Mazdas SkyActive modules.
This system is incapable of producing large power numbers as the entire chamber needs a more homogeneous mix of fuel, not just a small pre chamber. Check out how Ford use a combination of direct injection and port injection. Cruise uses the DI, where the demand for more power turns on the PI. No pre chambers here, just 12:1CR, and a very clever combustion chamber design.
F1 or not, 35:1a/f, 55psi and 19:1CR all sounds great in theory. However, nothing burns that lean. Even with a pre chamber. And if it did work, one spot of the head would get very hot, just like a Rotary and its hot/cold sides. Expansion problems would be bad as one spot on the head gets hotter than the rest. A recipe for cracking, or warping.
One day it might be possible, but there are a great many more leaps in both fuel and combustion technology to get to those numbers.
@@crd-nz_001 Well technically your right it was theory.
I take it your not a fan of F1 or been following the ICE regs since the sport went turbo/hybrid.
Here are some facts:
Mercedes was running 14:1 CR in 2014, 18:1 CR in 2017 when they relaxed to the 105l/ph fuel flow
I just said 19:1 CR to be conservative
Honda was running 40:1 AFR but was having issues and found power/reliability/fuel saving at 34 or 35:1 with 16:1 cr i believe (ill find you the video if you like?)
That one day of might being possible happened about ten yrs ago with 14:1 @55psi in 2014 with Lewis/Nicos engine
I guess for unintiated this would sould like theory but the technology has moved so far on from what your talking about which is the late 90s Di/Pi of Uwe Ostmann owner of Xtreme Di and Bosch/Audi LMP genius had ever created with piezo DI, so things "do" burn that lean.
This is before F1 went E10 btw
The added precision of TJI means you have more ignition and combustion stability bc u can precisely control ignition
Iit allows for a more reliable and consistent flame propagation & combustion process and reducing knock in lean burning condition. One of the F1 AMG engineers said the main factor of achiecing over 50% BMEP was TJI !!!
850+bhp from 1600cc?
Id say thats pretty capable of producing large power
HKS are claiming 600hp annd 5l/100km fuel efficiency on a 8.6CR 77.7m stroke on a 86mm piston on 98 tuned on a fcon v all with TJI
Imagine telling nissans enigneers they'll get that when designing the head in 87' just from TJI and 25 frame turbos
They probably would have had the exact same reaction you did
The only negative ive read they dont like being below 0c
Few things
*105kg/hour - max fuel allowed for ICE
18:1 cr is a limit that has been set by the FIA, i just thought 19:1 bc they 14:1 in 2014 and 18:1 in 2017, i was being conservative when i guessed 19:1 7yrs later
From Mahle - This system is compatible with conventional gasoline aftertreatment systems. In the ‘Active’ configuration a 2nd low-flow direct injector is incorporated into the pre-chamber assembly. This allows fuelling to be accurately, and independently, controlled in both the pre-chamber and the main chamber, enabling homogeneous ultra-lean combustion in modern gasoline engines, where mixtures leaner than λ=2 can be ignited while retaining stability.
One of the reasons FIA went this direction is "it achieves reductions in engine-out NOx emissions by more than 99% in the ultra-lean area"

Linkedin - Cedric Libert - some cool articles

Now that shit is all boring what is cool for us is that HKS have incorporated it into an RB28 wih pretty amazing results with what "looks" like a retrofit on a std 05u head. When you incorporate ethanol λ=3 your at 44:1 on gas and 30:1 on e85 and you can up the comp significantly. F1s now mandated E10 maybe thats how Honda hit 40:1 before settling on 34:1🤷🏻♂
HKS ADVANCED HERITAGE - RB26 - Concep YT vid 1m47s
some knuckleheads on SAU are claiming HKS have cast a special new 05u cylinder head to incoorporate this TJI - your not claiming that are you?
dont you think this is cool as a die hard RB fan?
Everyone is worried about the end of ICE sports cars, it's innovations like this that will keep it going. People still ride horses, and few mad hatters run foot races for the fun of it. We will still have our hobby! Thanks for sharing this guys! If you guys could even make improvements to the metallurgy alloys as you get the hang of this that would be amazing!
Seems like the original timeline for this to be released was a little ambitious...None the less great job.
Awesome work guys.... For those that cant afford Billet this will be a great alternative...
Can you integrate a crack into the block, but actually make it sealed so we get the genuine rb26 experience please.
😂😂
There's some way to go so far But everyone is waiting for the finished product 👍
If I had an unlimited budget, I'd totally buy it all
I like the look of the new Dart Iron Eagle 2JZ block too... 🤔
The muscle car we actually want
Cool Project 🏁👌🏻
Absolute legend
Herman is the man!!
There’s a lot of meat between the bores. Should be some healthy big bore sizes available 😊
PRP THE WORLD!!
Cool now rbs can be as reliable as a barra
That's impressive
or cast a new sr20vet RWD setup head that bolts up without a oil conversion kit and re angle the intake port ( basically where the intake manifold bolts too) to better fit a sr20det intake manifold.
one day ill get a PRP build for my 32 haha, 2.8 stoker plz
Wow. That's awesome. 👏😛
Amazing
Good on you man.
Not a GTR guy but it’s cool to see someone giving more options.
Interested to know if they’re generally a copy of the OG, a slight improvement or a significant improvement?
Will you serial number them?
send one my way, my r33 already making 1400awhp, limited by the block, ill push it.
Please make such a block RB35 and with two rows of crankshaft main studs as they did Dart block 2jz
Hopefully you sell thousands around the world
Whats the biggest size piston it will take whilst leaving decent bore spacing
Whats the weigth compared to a 24u
90mm plus decimals with oversizes… comfortably
@@hermanurriola138 90x90 square

Herman can we retrofit the HKS TJI Prechamber ignition they released on their new RB28 couple years back?
Its on a std 05u head?
understand if its a bit early to know
Wow very exciting
One day my Dato will have one 😁
this RB stands for Race Bred and Reinforced Bore now, not Ryutaro Ban lol siamese 6mm 300hrc omg!
Nice video
Great work! Will you be doing the RB30 block as well?
Probably won’t need to with this block.
time to sell crate engine 🎉🎉🎉🎉🎉
Regarding the heads, is there enough room in the ports to go for a very high tumble flow port like some modern engines? I've seen a lot more focus on combustion quality in the OE world and most of the aftermarket world seems to be about flow.
Hell yeah man
Very very kool 🤙
sr20 next?
Please 🙏 PRP can you do this for a 4g63! Prices for used Evo engines are ridiculous!
If they need help drafting it, I’ll volunteer my time for free. I love my Mitsubishi evolution and I’m PURE enthusiast and I want to help the community because these prices are getting out of control and it’s really hard to have some fun.
I’m currently in the middle of 3-D scanning evolution nine motor I don’t have the best 3-D scanner in the world but it’s done some of the work and the rest of it is kind of complicated for me I’m just a hobbyist and self taught when it comes to 3-D scanning and auto CAD, fusion 360
Going to be very interesting to see how much these cost compared to Dart's new 2JZ blocks.
Dart 5k usd this 6k usd
Is there an update on production?
I'm surprised dart haven't dun a rb26 block yet , maybe it's only a matter of time
can we get a video similar to the n1 vs stock block video? im curious as to what is actually better and different to a n1 block
Will do 👌
So when are you guys doing a cast aluminum block?
Price will be crazy
Nah for the head and block together is about 10,000USD so same and a used rb26 with all its issues

@@920.streetstyle that would be a a nice round figure 👌 👍
I've heard that cast EJ275 blocks are coming from IAG.
Don't they have billet ones. What is the difference - casting is more affordable? Or there is more to it?
@@idokwatcher2062 cast iron is much much stronger and cheaper. 2JZ is cast iron ;)
@@petkokrushev3840 Nah billet is way stronger and way lighter almost 50% 30kgs
Athough this casting is going to be rated for over 3k bhp
Billet has thermal expansion issues without getting technical. You need to heat it up first if you live in cold climates etc, not an issue in Sydney. This PRP block acts like a regular factory cast iron block with the simplicity and convinience that brings with massive hp capacity for a way cheaper price than a billet. Now that this is out every single person with a built RB not running billet is better off just swapping out all the internals into one of these for piece of mind cranks rods piston etc, and it doesnt matter what size u want to run or you currently have either 2.6-3.6
2.9mm bore vs 8mm bore...
Cool 👌👌
Herman, I need your expertise on my build I'm trying to do, I have a r33 gts4 s2 4dr(gtr 4wd/2wd drivetrain from factory), I'm wanting to use the prp block and head for my build but use a nitto 2.8l stroker kit and I'm just trying to figure all the details like the buckets and cams and possible upgrades like the 4wd sump(I don't want to go dry sump if I can avoid it) my hp goal would be 750hp in 4wd but have all my parts 1000hp capable, hope you see this
Why not aluminum with a sleeve to reduce weight ?
it sad that a new cast rb26 block from PRP is a better deal than a COP kit from them. a set of r35 coils are around $400/set, you're payin $1100 on a bracket you cant even see.
Bracket is $300 USD roughly. Don't know where $1100 is coming from...
Any chance of casting a RB20 block with 12mm cylinder walls 😂?
A 6mm oversize bore and short stroke crank and hopefully 12000rpm 😂
Extreme Tuners RB26 crankshaft
billet tungsten alloy dlc coated rated for 12,000rpm
I wonder why is it not be made out of cast aluminium to reduce the weight? does it reduce the strength significantly?
How many cast 6 cylinder aluminium blocks make 2000+hp?
@@MotiveVideo I see, my bad for not getting the point of it. I thought the purpose of it made are not just for the one who needs block replacement but also include that it might be used for improving handling by reducing block weight. Like a B58 6 port for instance, although I haven't seen one cracking above 1500hp let alone 2000+hp, it's a quite crazy considering it's cast aluminium block.
That's why I was wondering it would be crazy if 2000+hp could be achieved using cast aluminium using current tech and PRP's expertise on RB.
I hope it's lighter by a lot than nissan's original block although it's made from cast iron using PRP's expertise on how to bulletproofing the RB. I can't wait for the next update. Cheers
Send me a block to the US. I'll do the street testing. I'll put some real miles on it.
Don’t mind the wait, how about a lot cheaper!!

It comes pre-cracked just like oem
probably just rough casting! but will need thousands of kms testing to 100% know for sure too be able to sell and warranty

Well done PRP & Herman, keep up the great work 👍🏽 - I don't own an RB/GTR but still very interested in seeing this block hit the market !!!!
My only concern is that it's going to be unobtainable for the average car guy. You guys are going to want 10 or 20 grand or some crazy number. Even if the cats are perfect, the heat treating has to be on point, so much time and effort in R&D goes into this stuff. Best of luck. I hope you guys are successful

Something tells me the final version is gonna be made publicly available during either GT-R festivals.
A big question though is if these things are gonna be street-legal in Japan. It's not like they take your engine out during the once-every-two-years "shaken" test, but still.
Why shouldnt it be legal? Its not like you are getting an engine swap or something like that. Its just like the OEM block but stronger.
@@iamnoob8925 Exactly my thoughts. But then again, I don't live in Japan or own a car. Maybe I'm just wary about governments being buzzkills while hiding under the justification of safety or emissions.
Put your own engine number on it to match 🤷♂️
@@MotiveVideo Luckily its legal in Germany/ Switzerland. But i am wondering if you can run a 3.2 liter stroker in the prp block or is it only an exchange for the OEM rb26 and not the rb30?
@@iamnoob8925 2.6-3.6L
And everything in between
Its going to allow an RB30 with a short stroke 78mm crank and 90mm piston iirc
So an RB30 that revs to the moon....
Im not sure if it would allow it but a 92mm x 92mm "square" would make a 3.7 which is a fantastic mix between torque and revs and allows for massive versatility as a daily, oh and 3.7L
