EZ30R/EZ36R controversy
I am not knowledgeable in this field, so will not say anything on the facts. But the argument "I work at Subaru" is of no value. Fahrer4184 should bring in a verifyable reference rather than an argument of authority. That said, we now have two entries marked "EZ30D" which is, hm, not really encyclopedical. Jan olieslagers (talk) 06:27, 19 October 2010 (UTC)

Certainly, I'll be glad to provide a verifyable (sic) reference. See this picture here (https://farm1.staticflickr.com/944/42029291341_2cc810d515_b.jpg)? That's a VIN plate from a B9 Tribeca, which you can verify by the first 6 digits of the VIN which I left visible. Since all EZ30 engines have six exhaust ports and AVCS from 2005-up, all Tribecas (which came out in 2006) then have that same updated engine. Now... notice the engine code on that VIN plate? The first five digits say EZ30D. Whether it's "encyclopedical" or not is "of no value." So, there, it's settled then. I'm changing it back (again), and I'd like for it to stay.

Regardless, there needs to be an actual source proving so. A mere VIN plate is not a verifiable source. Also, drop the elitism act, please. Kensuke Nogami (talk) 19:16, 10 September 2012 (UTC)

A "mere" VIN plate is not a verifiable source? Umm... okay, then. Find me one single source of OFFICIAL Subaru documentation that has "EZ30R" written on it. Until you do, my source and my edits and my 'elitism' stand. Fahrer4184 (talk 16:22, 21 September 2012 (UTC)

I am getting sick of seeing this on my watchlist every week, back and forth!!! I have never seen EZ30R used as an official engine designation from Subaru, in fact I think it came from the Legacy 3.0R Sedan and the R somehow stuck on the internet. Now I retired from Subaru in 2006 and don't have much else to offer on this topic, but until we can get some additional documentation like a pic of it stamped on an engine block or someone scans a Subaru parts book with this designation then this little brawl needs to stop. I do agree that there needs to be some kind of difference noted between the two engines, so in the mean time why can't we just say 1st Revision & 2nd Revision or Single & Dual Port or something? Just my $0.02 worth... Sixthstar (talk) 18:39, 23 September 2012 (UTC)

Okay, since there are still people changing the entry back to EZ30R/EZ36R, I'd like to add another source from my parts catalogue at work. This is a screenshot from the Subaru FAST catalogue (]https://farm1.staticflickr.com/977/42029291421_e86943768d_b.jpg), and it goes by model code. I'm using the Tribeca again in this case, which is model code W10 (you can Google that). Now, I've selected the available engines for the Tribeca from the dropdown menu, and do you see what it says? It has two listings: 30D and 36D, denoting either the EZ30D or the EZ36D. If the engine code really was EZ30R/EZ36R, that dropdown menu would say 30R and 36R. So again, folks, I'm not trying to be pedantic. Those are the engine codes that Subaru use themselves, and if we're not going to use these codes, then there's no point in this entry even existing. Fahrer4184 (talk 16:22, 16 December 2013 (UTC)

I can't believe that four years later, people are still just changing this back to EZ30R whenever they feel like it with no valid links or sources. Here's another screenshot from the new online Subaru parts catalogue which is not only available to dealers and Subaru of America employees (https://farm1.staticflickr.com/951/27158829037_df8afa617a_b.jpg), but also to ANYONE who goes to parts.subaru.com to look up parts. I copied and pasted a random VIN off of AutoTrader, so I don't think I'm under any privacy violations for posting the whole VIN (that means that you can do your own research if you want by taking the VIN to your local Subaru dealer and asking them to give you the engine code). If you don't want to use a VIN, just choose the car as a 2009 Outback 3.0 and look up an engine assembly. Everything you need to know is in that picture above, though, and if you can't see VERY CLEARLY under "Other Info" that the engine code is EZ30D and not EZ30R, then I can't help you.

Adding 5th digits to F-series engines (FA-series and FB-series)
Using my resources from Subaru of America at the dealership where I work in Florida, I have done some updating to the F-series engines.

Here's what I've done:

- Changed "FA20 DIT" to "FA20F." Using the online Subaru parts catalog, I have verified that the engine code that Subaru uses for the 2.0L DIT engine that appears in the 2015-up WRX is FA20F (https://farm1.staticflickr.com/970/41309014434_2814172cea_b.jpg). The full engine code is visible in that picture under 'Other Info'. I have verified that Subaru also uses the same FA20F engine code for the engine in the 2014-up Forester 2.0XT (https://farm1.staticflickr.com/976/42029291381_9c91ae1174_b.jpg).

- Changed "FA20" to "FA20D." Using the online Subaru parts catalog, I have verified that the engine code that Subaru uses for the 2.0L DI engine that appears in the 2013-up BRZ is FA20D (http://i40.photobucket.com/albums/e244/fahrer4184/FA20DAWB9A_zpsb3klqxnn.jpg). Again, the full engine code is visible in that picture under 'Other Info'.

- Changed "FB20" to "FB20B" or "FB20X", and changed "FB25" to "FB25B." Using this VIN from a 2013 Outback (http://i40.photobucket.com/albums/e244/fahrer4184/2013OutbackFB25B_zpsb1fdc8d5.jpg), I have verified and identified by using the red boxes that the engine code that Subaru uses is FB25B. I have verified that Subaru uses B as the 5th digit for all FB-series engines in the United States, except for the 2014-up XV Crosstrek Hybrid, which uses engine code FB20X, as verified by this VIN (http://i40.photobucket.com/albums/e244/fahrer4184/XVHybridFB20X_zps665f2f2c.jpg)

These engine codes can be verified by anyone by going to parts.subaru.com and using the online catalog. By locating the engine assembly under Engine and Cooling, then clicking on the part number, under the green writing that says "This genuine part fits your..." and then the corresponding vehicle, the entire engine code should be listed.

I do not have access to any information from other markets besides the United States, so I did my best not to alter any information that does not apply to US models. If you can provide official Subaru documentation from another market that conflicts with the changes I've made, please post them if you make any changes.

Thanks.

GT30 and RS30 launch?
An IP editor recently attempted to make this change:

https://en.wikipedia.org/w/index.php?title=List_of_Subaru_engines&oldid=822015176&diff=cur&diffonly=0

Per our policy at WP:V, before accepting the change I need to see a source. Where did this information come from? --Guy Macon (talk) 08:16, 31 January 2018 (UTC)

EZ30D
Hi I accepted the  because we currently have two bullet points in a row labeled EZ30D and it seemed likely that the second one was wrong. Are they actually two engines both called EZ30D? Could the text be clearer about the situation? Mortee (talk) 23:10, 11 February 2018 (UTC)


 * I agree that this is confusing. Pinging our resident expert, User:Fahrer4184.


 * Please don't accept any edits that imply that the EZ30R, EZ36R, EJ20T, or EJ20TT actually exist. Those engines are internet hoaxes that keep getting reposted by website owners who are too lazy to check to see if what they publish is actually true. The reason we have pending changes protection on this page is to stop well-meaning newbies from adding false information they saw somewhere on the internet. --Guy Macon (talk) 23:45, 11 February 2018 (UTC)


 * I did Google it in quotes and got tens of thousands of hits including plenty offering it for sale. Looking now, none of the 8 hits for "ez30r"+"hoax" seem relevant. I don't know what else I could have done in a pending changes review to see that it wasn't a good edit, but now I've heard differently I'll leave the page to others who know more. Mortee (talk) 00:00, 12 February 2018 (UTC)


 * Sorry if I seemed to imply that you did something wrong. You did exactly what you were supposed to do. It is a difficult situation when so many websites have wrong information. but the fact is that no reliable source supports the existence of the EZ30R. See the thread at the top of this page. --Guy Macon (talk) 05:29, 12 February 2018 (UTC)


 * Sorry I'm just now seeing this. Despite the popularity of the engine code "EZ30R" around the Internet, Subaru has never designated any of their 6cyl engines as "EZ30R" or "EZ36R." Despite the significant differences between the 1st iteration of the EZ30D and the 2nd iteration, Subaru has always designated it as an "EZ30D," and the 3.6L engine has always been "EZ36D." You're welcome to review the material I've provided above in "EZ30R/EZ36R controversy"... I'm working on moving my pictures over from Photobucket (may they die a horrific death) to Flickr, where you can clearly see a B9 Tribeca VIN plate with "EZ30D" as an engine code... UPDATE: most links should work again, still hunting for other pictures, will update soon.

Ascent engine code revealed!
Official information regarding Ascent mechanical specifications has been released to Subaru internal and dealer employees, including the engine code, which is FA24F (https://farm1.staticflickr.com/828/41309024764_486ac178a9_b.jpg). Also confirmed is that the Ascent will use 0W20 synthetic oil, following suit with the industry's shift to synthetic lightweight oils. This is Subaru's first turbocharged engine to call for 0W20 oil (the FA20F in the WRX and FXT still call for 5W30 full synthetic). Fahrer4184 (talk) 22:35, 10 May 2018 (UTC)fahrer4184


 * Great job as usual. Thanks!


 * My normally-aspirated 2018 crosstrek specifies 0W20 synthetic but allows 5W30 synthetic. Similar turbocharged engines specify 5W30 synthetic only. Unless I am mistaken, the 0W20 gives you a tiny bit better gas mileage and the 5W30 gives you slightly less engine wear.


 * The 2018 (and 2017?) US model is called a "Subaru Crosstrek" instead of a "Subaru XV Crosstrek". Is this truie everywhere in the world? If so we should edit the page to reflect the new name. --Guy Macon (talk) 04:10, 11 May 2018 (UTC)

FB25 direct injection = new engine code?
and I put end dates on the use of the FB25B in Forester and Legacy as those have now moved to a direct-injection variant of the FB25 (2019 MY for Forester, 2020 MY for Legacy). There has been no corresponding announcement for Outback yet, but I'm confident the new Outback will also adopt the direct-injection FB25. I've also tried to figure out what the new engine code for the DI FB25 might be, but had no luck; I found short block assembly P/N 10103AD010 on parts.subaru.com but I don't see an engine code there. Perhaps I'm not looking in the right place.

I've also updated the Subaru FB engine article with references for the new DI FB25.

Cheers, Mliu92 (talk) 18:22, 6 April 2019 (UTC)

Sorry I'm just now seeing this, folks. The engine code for the new direct-injected FB25 follows suit with the direct-injected FB20 in the Impreza and Crosstrek. It is coded FB25D. I've edited the main article to reflect this.

To get the Subaru parts website to show you the engine code, you have to look up a complete engine assembly, not just a short block. Technically, the 5th digit in Subaru engine codes refers to the fuel delivery system. A short block has no fuel delivery system, so it cannot be assigned the code for one. This makes sense since short blocks are often modular parts (i.e. the EJ25 semi-closed-deck block for turbocharged Subarus is used in multiple applications, not just a WRX or STi), but the cylinder heads, fuel system, and turbine units are model-specific. So, to arrive at the engine code FB25D, look up the complete engine assembly by application 10100CD420 Engine Assembly, and you will see the engine code in its entirety listed right below the part number.

Hope that makes sense.

 * It makes perfect sense, thank you! Cheers, Mliu92 (talk) 14:29, 4 September 2019 (UTC)

CB engine draft article
I have created a draft article for the new CB engine: Draft:Subaru CB engine. It's not much, but it's a start for forming a new article. — R. J. Circus  –  contribs  -  talk  – 21:57, 24 October 2020 (UTC)
