RB26 Nismo GT Block Test - Unicon RB Block Myth or Fact? - Platinum Tech 

Dan Nagy you are exactly right 👍

@@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 So remind me why I want to use a GT500 block. I would think I'd want to use an RB25 or RB30 block after these tests.

@@trentmarlowe7655 Because wank spec ;) but why would you use a rb25/30 when a barra block is the best ;)

@@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

same i think but i didn't find a single video on yt about this

James Greig were working out how to test alloy blocks in a way comparable to iron blocks

@@MotiveVideo Once you figure that out, info on subaru blocks would be highly beneficial.

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.

@@lightmetalinc.6488 hence why comparisons haven't been posted already, in an effort to make an even playing field for analysis.

@@andymcdo u dont even need to test a ej block to know thst answer

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

@@ItsCardo1987 I just listen to Herman and think "yEp, mY eNgLiSh iS nOt aS gOOd aS HiM" 🤣😂

@@MafiaboysWorld swandive off a cliff 😂

Cardo_GTR he threw that in because some smart arse commented on another video that what he was saying should be called malabili......whAtever it is 😁😂

@@willemszchmilem7678 Oh Schnitzel boy, no one asked or wanted your opinion. Go pick on another 14yr old and ruin their curiosity for cars again you big man.... 🙄🙄 I'm off to work on my cars, have fun with your popcorn and ranting replies back to me like yesterday, I await your rambling 20 reply in a row BS when I return later. 👍

I doubt it, what made the GTR so amazing was the whole car, along with an excellent motor.

Just use a barra ;)

That's kind of depressing but then again also sort of a good thing for the guy on a budget build RB

@@Monstero5o difference between fg and x models? In terms of i6

@@willemszchmilem7678 Only way to beat us or be on par.

Jānis.P we have lots of comments online about it but we don’t really have access to any blocks

@@MotiveVideo when you will be comparing alloy blocks, is it possible to get m52 block?

@@exvils read the comments first without going blab blab

@@willemszchmilem7678 i read comments in every video in this series, which compare only iron blocks.. but since i seen comment under this video about plans for testing alloy blocks i had to ask, if it could be possible to get one alloy m52 which has nikasil coating... nowdays you can see trend in drag comunitywhere they use 2 styles of billet blocks - billet with sleeves and billet with coating

Motive Video I hope Herman’s block comes through! If not then someone needs to come up with awd 1/2jz setup into a skyline.

skylineandy they’re designed for 500ho so they won’t care

A shame, if they sorted out those issues it would be even more of a beast

Best Motoring has done tons of shootouts with tuned cars.

my chest cavity after reading this

BURN!

Damn that's good.

Hahaha...

pall

That's already been clarified but this isn't a jz channel

No surprises

well toyota raced 3SGTE 503 engine in jgtc and gt500 and in wrc so its good but size and weight are different story

So, a Toyota 4 banger 3SGTE > RB ;)

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.

I'm glad I wasn't the only one laughing during the live stream. 😉 RIP 🦄 motor. 😂🤣 The number of Barra swapped Skylines is going to rise quickly. 😎

@@MafiaboysWorld or the jz swapped one

@@MafiaboysWorld oh God... a barra guy.

@@CatBack94 Bzzzt, wrong answer but thanks for playing. 🤦🤦🤦

@@MafiaboysWorld yoU ArE juSt JeALouS Of my bArrA

Would be nice to know. I heard they are better once you ditch the headgasket for a metal one and retorque to 115ftlb. So ive heard.

I'm sure the FJ20 will be better.

Sr20 is aluminum block. Fj20 is iron. Fj20 wins.

Well, the only one required.

The key for being a Nissan owner who doesn't want to commit suicide, is not trying to understand Nissan

+1

With L28's it doesn't matter, F54, N42 they all vary a lot, you can go through 30 blocks to find a good 1 to overbore.

@@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.

@@gav240z its how it is man, heres to hoping you find that unicorn

Jean-Felix L'archevêque not true. They want the block to last. They replace everything else Supercar blocks can be used for 20 years. They just put new sleeve in once bored enough. Some Ford engines running today have been going 20 years on same block

@@MotiveVideo ill give you that because ya know you are some of the best with those but im wondering what is the hype over these yes rb are use in homolagation race car and have been use over and over in racing but they dont seem to be better in strenght than jz from what i understand from your test but they still make the power and seem to be "reliable" ( realisticly 1000hp or even 700hp engine needs a lot maintenance ) thank for the anwser

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!

Corporal Punishment it tests harder and it is lighter so clearly the material is denser and the acting design better

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.

Unlikely. Its a cash grab

You must be a late subscriber to our channel. We already did it December last year

ecotec 😂😂 bit of difference ?

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

@@willemszchmilem7678 why not? cast iron block that has been turbo and supercharged from factory.

@@markhalden3922 point being? It wasn't made to be a bullet proof engine and started changing as emissions did. Im not saying it can't make figures of 8, 900 it'll do it but won't like it. No matter what combo you put in the block the worrying factor is always chucking rods or cracks in general

CHACE NGUYEN thanks mate. We have lots more tech to come from fixing oiling problems to heads and engine building. The more views and subscribers we get the more we can afford

Jonathon Petersen we are in australia firstly. Secondly, if one of our sponsors or partners are involved in an engine, then we can’t validate the time/money it cost us to make the video We need 300,000 views for the video to pay for itself and that’s if someone supplies the block ready to go, or, we need a sponsor to pay for the feature

@@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

Block and crank are the same. GTE has oil squirters and different pistons/rods. That's about it.

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.
