In this episode of Technically Speaking we take a closer look at what is arguably Nissan's finest engine series - the mighty RB. Their popularity has been on a continual upward spiral since the mid 1990s but the RBs are not without their flaws. That's why we've invited a special guest Andrew Hawkins from Motive Video to our studio to cover the DOs and DON'Ts of an RB build. Covered in this video: • RB series history • Engine Overview: kzfaq.info/get/bejne/irljmal9zJi1lok.html • Tuning Options: kzfaq.info/get/bejne/irljmal9zJi1lok.html • DOs and DON'Ts: kzfaq.info/get/bejne/irljmal9zJi1lok.html Tell us what engine you would like us to do next in the comments section!

"R32 GD-R"

Haltec are killing it with content lately. Keep it up fellas

I like tuning fork. Great explainer, lots of knowledge, interesting to listen to. Thanks

The RB was such a wonderful engine. HKS actually developed a variable cam gear for the engine.

Many RB's lives were saved just by watching this video. The Aussie car content is awesome these days Motive TV, Street machine and haltech heroes are really doing an awesome job keep it up.

Here I'll just do everyone a favour and translate. ''GDR'' = ''GT-R''

We really want to run Heltech for our R33 GTR Build!

Loving the content ❤

Nice video but why does everyone who does a video on skylines forget that the R33 was the first mainstream production road car (Jaguar XJ220 aside) to do the Nurburgring in less than 8 mins. 7.59 by Dirk Schoysman.

Seriously feel smarter after watching this. Thanks for the in-depth dive into a lot of the "myths" surrounding these motors.

Aussie car channels are killing it lately with the awesome content thanks dudes. Me thinks the knowledge you guys bring forth helps save the lives of many an RB.

Love the passion you guys have for Japanese engines! All the best to both you and Andrew!

A video by the person who introduced me to Haltec! All bow to the great Tuning Fork!

Very informative. Thanks for taking the time to put this together. Cheers

I learned a good bit watching this video and enjoyed it very much. Thank you for taking the time to share it!👍🏼👍🏼

The r33 is my dream car and working hard for it

Thank you for mentioning the Australia Touring Car Series, most other videos I've watched on KZfaq don't mention the ATCC when talking about the R32 "Godzilla" GTR. More than the Japanese series it was in the Australian series and it's domination against the best from Australia and Europe where the GTR really made it's mark internationally, and eventually lead to the demise of Group A Touring Cars. And of course, it received it's name "Godzilla" from Down Under as well.

People do forget when they are building RB's, to put a integrated main-cap brace into it to avoid the block cracking, and they just crank up more power and end up dumbfounded when it inevitably cracks from load.

Hey brokosky, huge fan of you and the mates from MCM.. Love how you always, and maybe not even realizing it, have the ability too dumb down the information for simple folks to understand. You're very easy to listen to, and I hope your channel the best of success. It's great having all this knowledge at my finger tips at anytime.

Need a Technically speaking for the mighty SR20DET :D

Well, Nissan succeeded. That is all. And the car and it's engine became the word of mouth of everyone. A true legend(don't hate on me you 2JZ guys...)

9:10 maP sensor had me laughing pretty good. Love the video. Would watch more on more engines.

Nice Scotty. Nice to see Andrew dropping that knowledge on us too.

always enjoying your videos tuning fork. Cant wait for the next lesson on engines from you guys. If you would do the nissan vq series that would be amazing.

Great video.. love the RB series engine ❤

Man I respect this guys knowledge on RBs.

Great video, super informative. More RB / GTR content please! Looking forward to the Crank & Cam triggers video and how it works with Haltech.

Great video and info. This convinced me to build a 1JZ instead of an RB26.

I used to drive the pennzoil gtr! In gran turismo 3

0:23 Arby’s story really started to gain momentum with their iconic roast-beef sandwich. Yum

First video..just subscribed. you are well spoken..good pace etc. I especially loved how you made your "P" pop in MAP (9:10)

9:10 Map **POP** sensor

What a fantastic video.

Awesome video! Keep up the great work!

Love the videos guys keep them coming.

CA18!!! I know you had one back in the day mate ;)

Great vid my guy! Just subscribed. Btw, what’s the name of the intro song?

Really interesting video! Would love to see more of these!

Love this! Thanks for posting - you've got another subscriber. Hoping to see more on the RB26 as promised and need to find this other gent's material. Being expert on this fine engine is critical for those of of getting into these cars for the first time here in America. In fact, I'm looking at an R33 (legal in US as of January 2020) that a company here is importing from your land down under. Boy-oh-boy is it pricey tho!

Had a VL RB30, and common fault of warped exhaust manifolds and cracked heads got me as well.

A few similarities with the Ford Cleveland V8s issues. Core shift, split bores, pumping too much oil up top etc, an a lot of the same remedies. Really interesting

Thanks, Scot!

This was extraordniary. Thanks.

Awesome! What a great video of explaining RB engine for who planning to build one. Can you do same kind of video for Totoya JZ and Subaru EJ?

Weird timing. I'm literally going this afternoon to have an Elite 2000 and some goodies installed in my R32 GTR. Cant wait to drive it after!

I’ve got a RB30E in my GQ Patrol, what a wonder combination 🙌🏻

Just discovered this channel, today IS a good day :D

Nothing better than going to bed with Tuning Fork on a Friday night. OK thats a bit weird, love you tho Haltech no homo

My dream car is the 400R I want it so bad R33 gang

Great info. Guys! These vids. Are Great for us Car guys😁

Very cool! Thank you guys for sharing. While I might not have the opportunity to work on an RB26DETT any time soon, you did touch on a few things of general knowledge. Some of which I could not believe had not already crossed my mind. 🤦‍♂️lol

Scotty please cover the 2JZ-GTE, great info keep the videos coming

When tuning fork speaks. I listen. He's super smaht

Rotary breakdown would be awesome, love these videos. I've learnt a lot👌

Love it keep up the great work total pro respect scott

yall should do a video on the underdog of an engine, The vg30dett

My cars been on 750whp for 1 year and 500hp for 2 years before that still going strong stock bottem end

Very good information, great discussion, thank you.

Awesome info T.fork keep it up,RB-all the way!!!!! HALTECHWORLD

“GD-Ahh”

4g63 please!

So helpful going forward with my future build 👌

cool series, keep it up!

Because it came from the most successful sportscar bloodline in Japanese motorsports history.

The supra looks more like a boat than compared to the R33. Still a badass car though.

Tuning Fork should have his own TV show he explains things so well

Nice and interesting video nice to learn about the rb engine very well made just shows the old design engine are still advanced technology and quite reliable Well done for a lovely video Tbanks and thanks KZfaq

What's so special about RB you ask? When u put the & symbol between them, they make good soul rocking, love making music 😁

Awesome episode tunning fork, please do one on 1j, 2j and 1.5j.

Great video Scott . Thanks

I could listen to scotty talk all day, it’s therapeutic

Built by Japanese engineering gods!

Do an episode on the SR20DET please!!

Wow, show's you how much i knew about rb motors. Itb, No wonder they have such a nice note!

Excellent video

You can also upgrade to R8 aka VAG coils, much cheaper for the same performance and available worldwide unlike R35 ones.

YOU : RB KZfaq : *BARBIE*

Cheers Scotty 👍🏼

Great video!

Everytime he says RB's, I want to eat a shaved beef and cheese sauce sandwich on an onion bun.

I love the GD-Ahh engine

I just bought a gtst with the rb20 and I have to say all of the rb motors are absolutely fantastic

Great work scotty

500kw on stock bottom end.......lol, my block was worn out with 380kw in no time, circuit work will do that. The crank flexes and wears bearing and ultimately the block. RB engine harmonics are also a serious issue, this is why oil pumps break and crank noses break, it isn't just RB's, all inline 6's suffer from poor secondary vibration issues. This point is hardly ever mentioned with inline 6's and is one of its biggest problems and understand this is important and how it can wreak havoc if not mitigated and checked. My RB 28 broke after a few years of racing time attack too, the crank nose broke, this was on a full HKS built engine with nearly everything done to it for reliability, the secondary imbalances catch up with you in the end. Saying that drag cars will crack the block before a track car is laughable, the loads on a circuit are continuous for up to 20 minutes at a time and are experiencing harmonic imbalances for long periods of time. For me the RB is not really an engine I like that much anymore, they are very heavy, too long for packaging in a lot of cars, and In fact inline 6's are not really a good engine for circuit work or making a circuit car fast all together. The RB was a good engine overall, it achieved great things, but race cars have evolved significantly since the Bathurst. Drag racing is one thing, but the balance of a circuit car is a whole different ball game. One of the biggest issues when approaching 400kw and over is the use of twin turbos. I ran 500kwatw with GTX2863's, they were fantastic for response, annihilated any single turbo, even the EFR Borg series, but it came at a high cost, engine heat. It isn't from radiant heat issues as much as it is form having small rear housings so the exhaust can't get out as well, and the increase boost levels to compensate for reduced LPM flow rates of twin turbos. I was running 33psi and the reason why you can use a single turbo at 22-24 psi and achieve the same power level is because the turbo has a higher capacity (LPM), and when the inlet valve opens, it does not have such a drastic pressure drop as the piston draws downward (It hurts even more when using higher overlap cams), sadly overcompensating for lower flow rates, means increasing turbo pressure and thus inducing a lot of extra heat from increased pressures, this is by far the most important reason for changing to a single turbo over anything else. If doing circuit work I can't stress enough for the use of an engine oil coolers and competition radiators and the best inter-cooler you can find, at-least for twin turbos RB's, but the selection of a good single turbo like an EFR8374 or 9180 would be one of the first things to consider if looking at keeping it nice and cool for a circuit car. A steel crank, or crank girdle is a must upgrade for pushing a track car to these levels for long term reliability. The blocks crack because of weak cranks first, then harmonics second, crank girdles are great keeping stock cranks straight, but realistically a billet crank is the answer (maybe a girdle as well if you want bullet proof). Secondary harmonics ? Well that is a very hard thing to chase and cure and unless you have access to lots of vibrational analysis gear, it is a little bit of calculated guess work. Fluid viscous dampers can def help over vulcanized rubber variants and looking at lightened flywheels and clutch assemblies also helps a lot too, that is about all we can do.

Oklahoma license plate!

Great content!

Just to get an RB here in the States, it has to be imported from Japan, and it's pretty pricey. That bottom end brace is very much the future of high performance engine block building. Love the series and history.

R32 actually had around 300+ hp out the factory. They just couldn't reveal actual hp because of the gentleman's agreement in Japan amongst car manufacturers.

If Nissan would keep using this engine to replace all the lame boring fuel saving 4 cylinder engines, I'd want their cars for more than just its GTR cars

The Holden VL calis turbo was such an amazing car. It looked good & was fast. It was so damn good , the Australian engineers had to lower the engine below the radiator to ensure it would over heat & warp the alloy head to ensure it needed repairs to continue Holden's reputation of making junk as part of there company policy , in which to this day was responsible for customers leaving the brand to find better products.

Hello from Tulsa Oklahoma! Weird and cool to see our license plate on your shelf! Cheers!

Any one put RB26 head on RB25det block? I prefer the smaller stroke to bore ratio. A custom Billet RB32-34det that has same stroke/bore ratio of RB25, or even RB20 would be NUTS! Ever heard an RB25det with top shelf dump pipe and top spec, professionally configured full exhaust system? Beats the shit outta 99% of RB26’s I say we start a company that manufactures the turbo barra engine and exports them to foreign markets for reasonable price. Be hard to meet demand.... Imagine aftermarket sector for that engine if USA got their hands on it. They would be in EVERYTHING from skylines to 4WD’s to drift cars to boats even. Conversion kits and parts would be cheap as dirt. Who’s in? Lol

I was going to say something "clever " about the gdr, but thats already been played out.

I really like how you explain few weaknesses of the block. Single turbo vs double. Can you talk about the 4g63 next technically?

I and the r32 have the same birth year and month, no wonder its my favorite of all gtr's

Your name is TUNING FORK! not Scott! Great video

Problem with the oil pump gears is the stupid drive nissan used because it is cheap to machine. It makes the gear thin in 2 spots and when a crack forms there say bye bye to your engine. 2JZ has a proper spline on the oil pump drive..You don't know how many people want to punch that person responsible for this stupid decision. Same thing on the CA18 and SR20 oil pump..

I have a 2JZ and a RB26. Both fully built one with a sequential and the other T56.

Scotty you could have tried saying ,"And I love that you have brought me this present " and try to grab on to that brace , the look on his face would have been funny. Great vid & Cheers from NZ
