Absolute fact. I’m a Toyota guy (ST-205 GT4 and SW20 Turbo) but the R32-34 are objectively better sports cars than MKIII-MKIV Supras.

[@negativeindustrial]

CockYaLegS I fucking love mine. It has WRC electronics and turbo (with factory water/meth and anti-lag). GTRs just handle so much better than Supras but if you’re trying to go fast and relatively straight, there is no substitute for a MKIV TT 6spd

[@p4yat0t]

@@negativeindustrial It's true the R32-34 chassis are true sports cars, the Supra is more of a grand tourer / street cruiser than the angry animal that is the GTR. The Supra in the JGTC series didn't even run a 2JZ because it was too heavy, they ran a 4-cyl turbo, their WRC engine (4T-GTE), so basically it just looked like the Supra you'd see on a street since race cars are completely gutted, these "Supras" won some championships, but the Skylines dominated the whole decade without being too different from the street versions. The A80 Supra has its niche though being as wide as an SUV (seriously) an engine capable of 800hp+ w/ stock internals to go really fast in a straight line. Plus can't beat rear wheel drive. I can confirm the A80 doesn't really handle well by today's standard (feels like a boat) as I daily one, its pleasant to drive w/ power on tap if you need it. I can't see myself daily driving a R32-34 w/o going to jail, I would be doing time attacks to the grocery store and to work.

[@802Garage]

One quick note/question. You said almost double the flow when comparing the RB 7.97mm oil return holes to the JZ 15.5mm returns. Circular surface area goes up exponentially as you know, so the surface area of the RB holes is 49.89mm² each vs 188.7mm² for the JZ. So each hole actually has 3.78 times as much surface area, meaning that same factor of flow, unless I'm missing something. That would also mean RB total return area is 249.45mm² vs 2075.7mm² total for the 2JZ, 8.32 times as much return flow. Also makes sense if the 2JZ oil feed hole is about twice as large as the RB, which would provide about 4 times as much area. Pretty staggering difference if my numbers are correct. I'm sure that oiling capability really matters when getting into high HP.

Thank you, excellent comments. The bore pitch of the JZ is 92mm, of the RB 96.5mm. I've calculated the actual journal overlap (the enclosed area of the intersecting lens) of the 2JZ (stroke 86mm, rod 52mm, main 62mm) at 5.53 square inches, and that of the RB30 (stroke 85mm, rod 50mm, main 55mm) at 3.25 square inches, a huge difference. Coupled with the greater overall length, the 2JZ crank is much stiffer.

[@GTRPSI]

Mind blowing good info, very well done. Next one you should get Herman to discuss what the RB boys are going to reduce the issues. Drilling out oil returns to 10mm and adding head drain, oil feed holes bigger, annular oil groves to run 26 bearings, grout to support cylinder walls and his braces.

[@KeenanStyles]

Actually it's not the biggest advantage the A80 has over the R34 is the chassis itself it's more refined and aerodynamic. When you're in a A80 things dont feel cheap either like the R34 the biggest problem is the BNR34 was made based off an economy car counterpart and that absolutely sucks. The GT-R has a better weight distribution but the Supra is more solid especially at high speeds on a road course. Also at high speeds you dont hear creaks and rattles like you do with a R34 chassis. The ATTESA gives way better traction and it can ALOT easier to drive than the Supra depending upon which tires you run. In modern day AWD can be irrelevant based on that because I've chased down Evolutions and Imprezas with ease on the touge. I've even had an Evo VI understeer into the grass in front of me on a road course.

[@Buzdu22]

It actually makes sense for the RB26 to have thinner castings to save weight, after all it was built for the R32 to compete in Group A. The engine would not see extremes of power that would endanger it's integrity as it would be running restrictors and any extra material in the block would be dead weight. The design probably just got carried over to the R33 and R34 where it would not need more strength as only the R33 raced in Le Mans (again with restrictors), and all racing in the Japan GT circuit was limited to 500hp. The 2JZ on the other hand was built as a reliable, strong unit for a heavy street only GT ( Supra, Soarer and Lexus SC300) and was not constrained by weight limitations. The Supras that did race in the japanese GT championship did not use the 2JZ but the (racing only) 4 cylinder, 2.1 liter 503e.

This was an amazingly informative and yet easy understand video. Excellent work! I've been obsessed with the 2JZ for the past couple weeks since I rewatched fast and the furious on Netflix and then just happened to see a donut media video about the engine. With having watched over 20 videos on the 2JZ in the Supra this is by far the meatiest and most satisfying videos I've seen about the 2JZ. Thanks!

Money on the barra. Just because its newer. Newer iron mixes and better casting methods.

RB in my heart! Great information, thank you from Kazahstan! But you forgot tell about better colling system on rb blocks.

[@soundseeker63]

Be interested to see a comparison between the old 2JZ and the BMW B58 in the new Supra. BMW makes fine engines for sure but it has a lot to live up to!!

[@carboydorifutoparty3976]

Well that's just comparing a overbuilt 1jz vs a modular i6 with parts that are from a diesel i6.

[@lukaszbat3733]

I'm an L-Series and RB fan, but I agree that you can get more out from 2JZ than from RB. But let's face it, why would you need more than 400-600hp in a car (I'm talking about the street use)? This is the reliable hp range for these two engine blocks and if you go with twin-turbo, rather than single turbo you will get a monster with very minimal turbo lag. I enjoyed this video, looking forward to seeing more of this! :)

[@eddiewao2959]

Twin-turbo 600hp. Just about right

[@859romulus22]

Watch Motives single vs twins video. Single all day long in my opinion.

[@eddiewao2959]

[@corporalpunishment1133]

Excellent information and not fan boy bullshit. I use to prefer nissan over toyota but I don't like new nissan's at all. The RB came out in a lot of cars from cheap taxi's to the GTR from 1986 to 2001. The JZ came out in a more limited premium range I would say. Dose this reflect in the far better quality of the JZ. Many of us will never need to go in search of that much power so the RB is more than good enough. I would like to see how the quality of the ford Barra compares out of curiosity.

[@shawsie5780]

Corporal Punishment why settle for 2nd best if your building a car🤷‍♂️

[@debendragurung3033]

I don't think the RB30 came in the cheap taxis. This video is comparison of RB30 and 2JZ block. It doesn't say Toyota vs Nissan, GTR vs supra, not even RB30 vs 2JZ efficiency and power. It is just 2JZ vs RB30 - BLOCK parameters. For a mechanic / tuners like him - if he were to chose an engine block and tune the absolute best around it from ground up. He would definitely pick the better one.

[@100mostlyauthentic]

@@debendragurung3033 RB30's were in the Australian R31 skylines (and a couple of other markets), everything from the top of the range models to the pov pack base models with manual windows and unpainted bumpers had RB30's here. In the past the RB30s were generally looked down upon and the twin cam Rb20 and Rb25s were sought after.

[@sigmaprojects]

I don't know about that, the JZ block was available in tons of Toyota models. Very similar probably to Nissan's range. The JZ at the time went into almost every RWD vehicle, aside from SUVs and Trucks. For whatever reason Toyota spent more money on the JZ block than Nissan did on the RB it seems.

[@sigmaprojects]

@Mr Calcium Oh I don't doubt that Toyota spent quite a bit on developing the JZ. My comment was towards OP disagreeing with him saying that the JZ was a more limited production engine compared to the RB and therefore could be made at a higher quality. Although with your statement that Toyota had a small budget on engine development, where do you get that info from? I don't disagree that Toyota improved their inline six to compete more with others, but the RB25 came out three years after the 1JZ. And going back to the RB20s I don't know how they were blowing away Toyota's offerings? The 5M-GE was a much larger displacement engine and the later 7M-GTE was much more powerful than the RB20DET of the time. And even if you compared it to Toyota's direct competitor offering the G series motor toyota had the 1G-GEU and 1G-GTE around the same time as the RB20s, both being 2.0 inline sixes and both putting out the same power figured. From what I can see is that Toyota and Nissan just were competing with each other like usual.

[@AndrewEG]

Hardness testing has little bearing on the block's strength. The only way to gauge the material's ultimate tensile strength, without destroying the block, would be to take a tiny sample of cast material for spectro analysis. From there you can determine the composition of elements used in the casting and then look up the grade of iron used. Most Universities would have this capability so look up contacts at your local uni who focuses on material science.
