Great page, how about some stroke @ bore measurements, materials? This is supposed to be the greatest line of engines ever...-CW70.26.11.45 05:04, 8 December 2005 (UTC)

yea I will find some measurements, strange that no one has said thet all RB engines are alloy head with cast iron block, same as nissan CA engines
CAs are RBs with two less cylinders :D
Had to change some stuff.
Copied some bore/stroke stuff from the Japanese wiki, also some other power/torque data. Some values changed, not necessarily correctly? Please repair as necessary. Dimensionally I think the ground is firmer, but output not sure. I've some scanned PDFs of what purport to be R31-R34 RB service manuals, plus real paper R31 service manual, which doesn't match R31 PDF, which I now suspect is scan of Holden RB30E service manual, figure was probably valid, attribution was wrong (apologies), and have seen various different values given in magazines/books. Pick a number? Standardised power unit format (section format too) throughout the article would be good, I didn't change that. Maybe a timeline of engine availability too.

[edit] RB

Does Nissan claim "RB = Race Bred" or is this what everyone assumes?—The preceding unsigned comment was added by 139.168.57.242 (talk • contribs).

I don't know who put the sentence in originally but I provided a source for it, and it comes from a book by Andy Butler, a UK motoring writer. While researching his book he talked to Watanabe Kozo & Iwata Kojun of Nismo amongst other Japanese people connected to the GT-R. It's a sourced statement, which someone has just deleted. If someone wants to delete it again, please provide a source to back the deletion as per Wikipedia:Verifiability. Verifiability, not truth. RB30DE 09:34, 15 September 2006 (UTC)
It might be verifiable, but there seem to be more sources against it. A quick Google search showed http://experts.about.com/e/n/ni/Nissan_RB_engine.htm;
" The "RB" name is mis-construed and thought to represent "rhythm & balance", or "race bred". This is not the case, it simply is a "series designator". "
Not trying to create `original research', but if CA, KA, VG, etc don't `stand' for anything, then chances are that the `Race Bred' is simply an enthusiast construct, ie `bad reference'. I suggest even mentioning this in the article, if sources can be found to show the opposite. //Biggoggs 15:56, 16 September 2006 (UTC)
That search result is an (older) mirror of this article. I agree the reference could be wrong (it does seem incongruous), but my understanding is that wikipedia follows the reference not the truth. I rate a motoring writer's book higher than a website in terms of reliability, but one never knows. If the meaning of "RB" was left out entirely, that would be fine too. Or, as you say, listing it as a enthusiast construct/bad reference when something else turns up, seeing as there are contrary views about it. Perhaps copy both versions to discussion page and remove from article? RB30DE 01:02, 17 September 2006 (UTC)
I don't think it should be removed as someone may feel inclined to add it. While I agree a published book is more academic than a website, it strikes me as being implausible, and so counter-references should be `out there'. I'll modify the line a little. //Biggoggs 05:09, 17 September 2006 (UTC)
Fair enough. (Search results show a lot of forum shit-fights about it - classic!) RB30DE 09:00, 17 September 2006 (UTC)

[edit] Clean Up

Was there any specific criticism that led to the cleanup tag being applied?210.0.100.153 01:12, 20 May 2006 (UTC)

I guess not. I think we should discuss removing the cleanup tag, quite a bit of work has been done since the tag was added in April. //Biggoggs 08:14, 15 August 2006 (UTC)
Alright let's remove it. It's gone! Put it back if you feel strongly about it. I think the article is roughly comparable with the SR and CA articles, which are unmarked. RB30DE 11:04, 17 August 2006 (UTC)

[edit] RD block compatible with RB head?

I had never heard of this being done before, which is not to say it's not possible. I'll keep an eye out to find out what I can about this, but anyone else know more?210.0.100.153 01:12, 20 May 2006 (UTC)

[edit] Entry for 'RB20' motor

The motor pictured is an SOHC RB30E from an Australian R31 - 202.14.194.200 2006-06-16 20:10:50

Yeah I think you're right, although if it were a Japanese R31 could it still be a 20? I saw this engine (RB20E) in entry level Commodores and Cefiros. RB30DE 03:27, 26 June 2006 (UTC)
I changed my mind, I'm pretty sure this is an RB20E. Look at the height of the rocker cover, and compare with RB30E. You could fit the optional HR31 strut brace across the motor pictured, but there's no way that strut brace will go across an RB30E, it fouls the crossover pipe. RB30DE 05:42, 26 August 2006 (UTC)

[edit] Page Length

Why is it that the RB Engine page is longer and more detailed than the Skyline /GTR page? After all the RB is only one part of the Skyline as a car and the Skyline is more of a legend/symbol than even the more-than-legendary RB Series Engines which are rightfully considered one of the greatest Engine Series ever (especially the RB26DETT).—The preceding unsigned comment was added by 219.88.36.26 (talk • contribs).

It just depends on who writes what when, it's random, or at least non-deterministic. If you want to expand the GT-R page, go for it. I was kind of thinking myself that the way the information is split across Nissan Skyline and Nissan Skyline GT-R could be improved. The general Skyline article is quite long, and contains a lot about the GT-R, more than the GT-R page. Perhaps the meat of the GT-R stuff on the Skyline page could go to the GT-R page. Then there's Nismo GT-R Z-Tune floating around in the breeze which could be merged into GT-R. RB30DE 22:52, 19 August 2006 (UTC)
I disagree. The RB is used in more than just the GT-R; and as RB30DE said above, if you think the Skyline pages are short, feel free to update them. //Biggoggs 15:56, 16 September 2006 (UTC)

[edit] BS!

What means the BS at the RB26DETT? —The preceding unsigned comment was added by 84.164.239.181 (talk • contribs).

It means bullshit, actually it's right, there's no way a stock RB26 bottom end will support 1000kW. Didn't see that. RB30DE 08:12, 23 August 2006 (UTC)
The RB26DETT can hold 1 mw (1360hp)!! —The preceding unsigned comment was added by 84.164.239.181 (talk • contribs).
Perhaps it has been done, but certainly not on the standard bottom end, which according to my reading starts letting go at about half of that (I don't own one!). If you've got a source for a modified engine of that output, by all means add it to the article, as an example of the potential. Incidentally I was looking for Australian tuner references to support "In Australia, many tuners have produced RB30DET engines producing upwards of 1000rwhp." but what I find negates this entirely, so without a reference I think it's got to go. RB30DE 00:07, 24 August 2006 (UTC)
The block of the RB26DETT can hold 1360hp! And can bored to 2,8L (2,777cc) or so. —The preceding unsigned comment was added by 84.164.239.181 (talk • contribs).
Oh just the block. You still need a source for this stuff. The sources I have don't support that. RB30DE 02:14, 24 August 2006 (UTC)
1360hp with ORIGINAL block.
http://www.exvitermini.com/ (spec.)
Tuning without changes are not possible. ;) But the block is originally. The RB26DETT has a high power-potencial. :) —The preceding unsigned comment was added by 84.164.239.181 (talk • contribs).
Wow! Yes, very high potential. My apologies, I'll add it. Thanks for the reference! RB30DE 03:07, 24 August 2006 (UTC)
Hi, RB30. There's also an article in the July 2006 (#186) issue of Turbo and High-tech Performance magazine detailing an RB26 on the stock block (Nismo crank, however) doing about a thousand HP on a giant T88 turbo from HKS. You could cite that if you like. The RB is a pretty stout motor, much like the 2JZ engines from the Supra ilk. Positively legendary. ... aa:talk 05:27, 15 October 2006 (UTC)
Hello. Thanks for the info. Probably better if you add it since you've got the source. Fill in the blanks if you like:[1] Cheers! RB30DE 08:31, 16 October 2006 (UTC)
  1. ^ (July 2006) Turbo and High-tech Performance #186.
Just looking at the addition, I would like to reword slightly. The strengthening of the bottom end doesn't create power, it is so the bottom end will survive the power. The power comes from the head/turbo(s)/exhaust/intake, at that power level there's porting/cams/all kinds of tricks involved. It also looks a bit like 1MW is routinely achieved, when it's pretty exceptional mortgage-the-house stuff. But then how much detail to include? RB30DE 03:25, 20 October 2006 (UTC)

Is the 2JZ with original block, too? But the RB26DETT can tuned to 450hp with originaly crank gear. I have heard many of this engines can ride over 100.000Km. I have heardy about a RB-engine with 1600hp! But i don´t think that. @the 2JZ is an 3,0L engine and a 3 L engine can produce more HPs.

I have heard Nismo can take 1700hp from the VH35L from the R390 GT 1. But i don´t believe this. But think: 2,6L (1360hp) 3L (1520hp) and 3,5L (1700hp)... There is an sykline with 1360hp and it´s a legal version for the road!!

And at least look at the GT 700 they only made this track-speed with 66% of the power potencial. And only with 11,500rpm!

[edit] RB26DE

I'm not aware of a naturally aspirated RB26 block, but an anon user added this today:

==RB26DE==

The RB26DE is a DOHC engine with 24 valves. It produces 220 ps @6800 rpm and 245 nm @5200 rpm. RB26DETT in NA (Naturally-aspirated engine) conversion and forging piston with high cam private tuning. It was only used in the Nissan Skyline GTS-4 (R32).

I have removed it, as I think the user is trying to say that with private tuning (e.g., at a speed shop, not Nissan's OEM product) a non-turbo RB26 (termed "RB26DE", naturally) would produce such-and-such horsepower. I'm not aware of such a motor, but go ahead and put it back in the article if you can source it. ... aa:talk 05:23, 15 October 2006 (UTC)

Hallo,
i found it here:
http://ja.wikipedia.org/wiki/%E6%97%A5%E7%94%A3%E3%83%BBRB%E3%82%A8%E3%83%B3%E3%82%B8%E3%83%B3#RB26DE
I think it is the same block, but without turbo.
I have translate it with google... —The preceding unsigned comment was added by 84.164.209.119 (talk • contribs).
The addition surprised me too. Following link to Japanese wiki, what google didn't recognise was "Autech Version", according to that there was an Autech GTS-4. RB30DE 21:06, 15 October 2006 (UTC)

Google-Translation is a little bit strangely. :D But i can´t japanese. ;)

Can i add this text in the RB26DETT summary?:

[edit] RB26DE

The RB26DE is a DOHC engine with 24 valves. It produces 220 ps @6800 rpm and 245 nm @5200 rpm. RB26DETT in NA (Naturally-aspirated engine) conversion and forging piston with high cam private tuning. It was only used in the Nissan Skyline GTS-4 (R32).

How about this?
(From Japanese wiki) Autech made a small number of R32 GTS-4 Skylines with a naturally aspirated RB26DE conversion. The engine used forged pistons, a higher lift cam, and a tuned ECU. It produced 162 kW (220 ps) @ 6800 rpm and 245 nm (25.0 kgm) @ 5200 rpm.[citation needed] RB30DE 03:03, 20 October 2006 (UTC)

Yes. That´s good. :)

I have write this so. Is that ok?

[edit] Needs a new cleanup

I'm not going to add a cleanup tag because it's not that bad, but it does need some work. I've chopped, changed, and added to the article, but more could be done.

Some possible suggestions;

  • I've moved the bore & stroke measurements into their own section- should they each be integrated with its own corresponding section?
  • Power/torque figures seem unordered and scattered around the article- perhaps placing it in tables may make it easier to read?
  • More `flowing' sentences, eg instead of `Etc. Etc. Etc.', get it to `Etc, so etc, because etc', if you get my drift. etc :)
