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

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

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

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

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.

my chest cavity after reading this

BURN!

Damn that's good.

Hahaha...

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. 😎

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

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

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.

Unlikely. Its a cash grab

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

I'm sure the FJ20 will be better.

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

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

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

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

StickProductions2121 might as well sleeve a $300 block then

Jim Craig Please?!?

Adam Bainbridge blocks are same in most of them

@@MotiveVideo thanks for replying! I thought so. Expecting a lack of oil squirters maybe, but otherwise hoping they are the same. Do you know if the na neo heads differ at all?

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.

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

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

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.
