SUBARU EJ20 / EJ25 - What makes them GREAT? ICONIC ENGINES #13

- What is up engine heads! Today it's time for the first ever boxer engine on Iconic engines!
And of course we're starting out with Subaru's mainstay engine, the EJ20 and EJ25 engines.
Although the Impreza made the EJ20 famous, the Legacy was the first car to have it. In 1989 Subaru introduced the first generation of the Legacy and with it the EJ20 engine, which was designed to replace the EA engine. Now the EA engine wasn't bad, but by 1989 it had become a bit ancient. The EA engine was introduced way back in 1966 to power the first ever front wheel drive Subaru car, the Subaru 1000, and from that point onward it powered more Subaru vehicles, most notably the Leone, the Brat and the 80s-tastic XT.
Unlike many manufacturers that first introduce low performance version of an engine and then upgrade it later in the production run the EJ20 was available in three versions from day 1 in the Legacy. A SOHC, a DOHC and a turbocharged DOHC engine, with pretty impressive hp numbers right from the start.
But in 1992 magic happened. Three letters combined to create something beautiful.
WRX. World Rally Experimental. In November of 1992 the first generation of the Subaru Impreza WRX debuted and with its turbo boxer, stiffened up suspension and symmetrical all wheel drive it brought rally inspired technology to the masses. In 1994 letter soup magic struck again. STI, Subaru tecnica international which further enhanced the WRX recipe with even more rally awesomeness. The EJ20 engines in the STI Imprezas churned an impressive 250 horsepower from the 2.0 blueprinted engines. Each of these engines received special attention and dedicated tuning which is why only one hundred of these were made per month back in 1994.
Just 1 year later Subaru proved that it had a winning recipe because in 1995 the EJ20 engines in the rally prepped Imprezas took both the Driver's and manufacturer's championship titles in the Wolrd Rally Championship, bringing these cars international fame. Subaru would take the both titles two more times, cementing it's dominance in World Rally before withdrawing from WRC in 2008.
In 1994 the larger 2.5 liter EJ25 enters the scene in Japan and by 1996 it was on the US market. Designed to respond to the instant torque needs of the American consumer the larger EJ25 started life in the Legacy and the Outback but spread quickly to power the majority of Subaru's vehicles including the Impreza, the Forester and the Baja. Starting with 2004 the larger EJ took over as the engine of choice for both the WRX and STI imprezzas (not in Japan) as well as the high performance versions of the Legacy, Forester and the Outback.
But did you know that an EJ engine also powered a SAAB? Yup, in 2005 the Saab 9-2x was introduced to the US market and as you can see it's not really a SAAB but a rebadged version of the Imprezza. Here's something else you might not know, and that's that the EJ20 engine existed in twin turbo form. From 1994 to 2005 Subaru installed twin turbo ej20s into Japanese Legacys and Australian Liberties.
All EJ engines can be divided into two phases.
Phase I: EJ15E, EJ15J, EJ16E, EJ18E, EJ20D, EJ20E, EJ20G, EJ20H, EJ20J, EJ20R, EJ20K, EJ22E, EJ221, EJ25D
Phase II: EJ151, EJ161, EJ181, EJ201, EJ202, EJ203, EJ204, EJ205, EJ206, EJ207, EJ208, EJ222, EJ251, EJ252, EJ253, EJ254, EJ255, EJ257
Phase 1 covers fron 89 to 98 and Phase 2 from 99 and onward.
When it comes to the engine block all ej engines feature aluminum blocks with cast iron liners and aluminum heads. The EJ engines are an extremely rare example of an engine that can be found with a closed deck, and open deck and a semi open deck block. Early turbocharged ej20g engines produced until mid 1994 featured a closed deck with oil squirters for the underside of the piston. These are pretty rare nowadays. Starting with 1995 open deck block engines appeared and stayed in use for some naturally aspirated and ej205 equipped WRX, but starting with 2001 the vast majority of turbo ej engines feature semi-closed decks.
Compression Ratio: 9.5:1 - 10:1 (9.5:1 - 10.7:1 JDM) Naturally Aspirated
Compression Ratio: 8.0:1 - 9.5:1 Turbo
The block castings for EJ20 and 25 engines are virtually the same despite their different displacement. The EJ25 achieves greater stroke by using a different crankshaft and bored out blocks but uses the same length connecting rods as the EJ20 engines. This results in a different rod ratio between EJ20 AND 25 engines.
The tuning aspect of the EJ engines is unfortunately filled with misconceptions that refuse to go away and resulted in a reputation of weakness. Fact is that the vast majority of EJ engine failures isn't due to design, but due to the wrong tuning or the wrong parts. People with actual know-how build these engines to well over 1000hp today.
A special thank you to my patrons:

Can you please do a 1LR-GUE Engine? I'm really fascinated about that engine
Great engine! Good videos man! Make a video with 1.8 20vt! Vag pleaseeeeeee
I really like this Channel 😍
The factory oil pick up does not fail at all, unless someone jack the car by the flimsy engine oil pan instead of the actual jackpoint at the subframe, as well the aftermarket oil pick up tube has a angled inlet port (factory is cup down so it’s always the lowest point of the pan) which causing the oil salvation when under extended curves on certain track or a freeway on/off ramp because the inlet is no longer in the oil. I have seen more engine failure on professionally driven engine than amateur driven engines. That’s just something from my 10 years on working on Subaru. Cool info vids keep it up!
@@SpeedingSideway there is oil pick up issue on certain years of EJ turbo...but not all. They do crack around the normal oil level height. My legacy 2002 does not have this issue.
They made 555 of the Subaru WRX STI EJ20 Final Editions because of the tobacco/cigarette company “555” that sponsored them in rally. The “555” can be seen on the famous Colin McRae livery of blue and gold
And I tried 555 cigarettes and damn they are rough!
K Wang I haven’t smoked cigarettes in a long time but I want to buy a pack just because they sponsored a rally car lol.
@@iroquoispliskin6077 Don't do it anakin!
@@keithw4920 That's the brand my dad used to smoke when I was a kid.
Look at the number of views lol 555k
Refreshing to see someone not talking smack about the EJ platform, great video.
That’s just the haters squawking, I have 180k on my original WRX and no problems yet
@@villedocvalle First off, I want to start out by saying that I owned a '98 2.5 RS with a '98 JDM STi swap. After owning the car for 8 months, on a casual drive home my engine just let go. I was doing 80 KPH in 4th gear - I was not pushing the engine whatsoever. The engine was on a stock tune, so it wasn't anything relating to that. I always let my turbo engines warm up for 2 minutes minimum before driving off and even wait 2 minutes when I finish driving (Yes, I am too cheap to buy a turbo timer). I loved this car(she was freshly repainted pearl white; I called her Kate Upton) and I did everything I could to take care of it, to make sure it wouldn't break. I changed all the fluids when I bought it, had my mechanic give it a once over, after I gave it a once over - I even did my oil changes early.
I have no hate for subarus but their faults are VERY real - the only person you are kidding, is yourself. Also, if they didn't have unequal length headers, they wouldn't have half following they currently have.
The next time you change spark plugs on your car, you might start "squawking" about the joys of subaru ownership... Enjoy haha.
Sav yeah no, sounds like you’re builder went cheap and used a USED oil cooler. Reusing old oil coolers kills more rebuilds that you can imagine. It’s almost always the main culprit. The only real way you EVER make sure that good quality parts are going into you’re car is by putting in your self.
Sav and saying it let go without saying exactly what went wrong sounds like a troll comment and not one from an ACTUAL owner. A passionate owner would to tell you ALL the details.
No engine “just let’s go”. Something failed. What failed? Sounds like you got ripped off.
@@SupraSav The fact that you didn't know your turbo is water cooled and doesn't need a turbo timer shows how little you know. You probably had no oil in your engine.
Can confirm mechanics here in Japan absolutely hate working on my twin turbo EJ20 inside of my legacy B4 😂
don't know why. You just charge more labor. if the customer is willing to pay, i'll fix anything
and i was thinking its only me with my huge european hands
@@lostnumbr how to explain that just spark plugs takes 20 minutes... sometimes they do not understand what kind of care this geme needs
@@boobrowsky on some cars just spark plugs can take a hours. If it's so easy they can go home and do it themselves.
@@boobrowsky 20 minutes for spark plugs on any EJ is fast. You have to remove so much shit just to be able to access the plugs that it can take 1-2 hours for most mechanics - at least that's what the ones around me charge in labor hours. I haven't had to replace mine, yet, but I'm not looking forward to it.
555 for the WRC livery. Also 22b is the hexadecimal of 555.
Of course, that is THE reason...👍🏾
No way, I just checked and it's true. Omfg
22b also the hex color code for the iconic blue livery
Oh wow no way
555 is also a cigarette brand
I've never owned a car that I like better than my second gen legacy wagon with the ej22. The engine is amazingly well designed and without any glaring flaws. It's what normal car engines should aspire to be. Performance is another matter, but the world doesn't run on performance engines, it runs on daily driver engines.
🎯
lmk about the long term mileage report, I'm still iffy on subies
@@silver1407 No need to be iffy. Naturally aspirated enginss except for 2000s 2.5L EJ are very reliable. Subaru cheaped out on the gasket in 2.5 for some reason and its only reason why it fails in that version of the motor. Turbo motors are similar story. EJ25 is one ridden with most issues but majority ofnit is specific to UEL exhaust manifolf variants plus abuse and ignorance of US owners of these who put too low octane fuel in it all the time and generally are ignorant to how turbo engine should be tended to. Newer EZ30/EZ36 H6 engines and FB amd FA series motors are rocksolid, toyota level reliable. Tho early FB series have mild oil consumption issue but its not too bad, and was fixed unlike Audi/VW turbo 2.0L oil consumption issues(and catastrophic failures that plague VW TFSI motors from similar period). FB motors made after 2013 have no oil consumption issue. I have 2012 XV and its not really too bad, not more than my old Toyota Celica 2.0 burned.
But what in ANY way would make it better than even a K series? They are truly NOT reliable, maybe average but your common issue being head gaskets is a very bad common issue to have. They can be “reliable” but they usually are never. They can make power, but why build a EJ when you can build a 4G63 or 4B11, both make as much if not more power WAY more reliably. I just can’t see the other side to the argument man.
@@yoshi2413 ok. The head gasket issue isn't present in the EJ22, which is the engine I posted about. It is also very easy to work on. Also, those 4 cylinders don't come in subarus. the honda and mitsubishi are interference engines.
Speaking of the K series, I've worked on 4 of them in the last week. 2 front main seals pouring oil, harmonic balancer was cracked on one of them. One had rod knock, and the 4th had jumped time due to chain guides wearing out. Interestingly no subarus have turned up in that time.
the thing i really like on an EJ25, is the way the con rods come flying out of the block. makes it much easier to access them 👍
Look I had 03 evo and when I bought it it had 18k on it and a Greddy catback I loved it I had a friend that that his friend tuned evos now that being said I hat my friend put the bigger fuel pump in we both put the injen intake upper inner cooler and lower cooler piping in put the downpipe and he said his friend could put the gs1 cams in then got it tuned it blew the engine within 2 weeks now was it the tune the cams I don’t know so my father in-law put a 2005 evo engine in and he cleaned that blown engine better than anyone I went and got the cams put in professional after that and went to New Jersey to Ivey tune and got it tuned and it mad on stock turbo 338 whp and 339 tq I wish I never got rid of that then I got a 2014 evo kept it stock I didn’t like it now I have a wingless 2017 stock sti and love it it reminds me of my 03 evo when it was stock beside the cat
I have a B4 Subaru Liberty, runs like a dream after nearly 300,000km

My 04 STI is still on its original engine 229,646miles at the time of this post. Upgraded turbo to a 16g with EL headers I made 287whp seems like my compression is holding up. Oil changes every 2,500 since I bought the car at 116k. I love my Subaru ✌️
What oil do you use?
@@jameskocks4734 I've got a similar build except 08 sti. My tuner uses shaefers diesel oil in it.
bs
What u at now?
Great in depth vid! Thanks for all the history of this great engine. I have a 94 Loyale with EA82 and 2 EJ25 Outbacks, love the feeling of history and continuity of these cars. All are over 180k miles and run great from hot summer to -15 degree winters. Dodging deer, tourists and boulders these keep us safe and are fun to drive every time!
Great video. We have had 8 EJ25 Liberty (Legacies) in the family since 1999 in both non turbo and turbo editions. With correct servicing and keeping the oil up to them they last forever. The most we have got out of 1 engine without any modifications was 420000 km. Only then it was the gearbox that gave out.
My wife currently has the EJ25 B4 Spec B with the special tune in it and it flies. Super reliable and a fantastic vehicle with 240000 km on the clock at the moment.
Brilliant cars. Great engines.
If they last forever why would you buy 8 of them?
Really love this series! Eagerly awaiting the next ICONIC ENGINES!
My dad had a manual Subaru GL wagon, 1984, that ran for 22 years, through Germany, Texas, California, Italy, with over 230k miles on the meter, before selling it to a college kid. I now own a 2018 Forester, manual, of course, and am trying to learn all I can on the history and specs of the car and brand. Very insightful video. 👍
Scotty Kilmer needs to watch this and learn a few things about Subaru and boxer engines.
Great education video.
Thanks for making it.
Congratulations on research well done, pretty much all of those dates, power figures, models etc were all correct! Hats of to you good sir, good job.
Thanks for all the great info. Love my 2017 sti. Just went stage 3. I will keep it forever.
Mad props to you for remembering the Citroën GS boxer 4-cylinder. I did my apprenticeship working on them. No engine ever leaked more oil, but some of the early versions had needle roller crank bearings!
thanks heaps! very informative and reassuring for someone who is about to begin modification on their EJ20 :)
last july was my 31 years in subaru and i work on them too
Subaru's EZ family of engines are just as amazing! The EZ30D and EZ36 are amazing powerhouses that I'm exceptionally surprised aren't far more popular. I do love my EJ22T and EJ255 engine cars immensely as well though.
Outstanding video. Completely full coverage of the subject. Like all of other videos. Thanks very much✊
555 it's a play word by Subaru. It means 2 thing, 1. is team rally that used cigarette livery on WRC back in the day 2. 5 in japanese is "go"
so 555 in japanese can read as "go go go", basically you cheering & support Subaru.
It a shame that Subaru no longer do WRC. I would pay money to see the STi WRC car again.
@@linchester8464 I really hope they get back into it just for fun. They need to make a slightly smaller platform like a 2 door Impreza based hatch to be competitive. Bring back the Justy name? Hah.
@@linchester8464 I think they are doing WRC with next gen STI!
@@linchester8464 Q. How much could we all pay to see that?
A.
Well, not as much as Subaru would sink into wrc. The development is linear yet the cost compounds.. If you want the blue stars to make cars, they're going to have to be brilliant.
WRC has changed, Subi took the 90's wrc, brought the wrc to America..
Then Lawyers happened.
#1, Toyota is done with wrc, and Le Mans and is racing nascar..
why?, $$$.
I agree with you!
... Yet I dont watch wrc anymore.
I guess, time changes everything.
Amazing job! All the real life essential information needed for a Scoobie enthusiast! Well done dude!!
Really appreciate the video & your channel is awesome. Love my phase 1 EJ25D. 300k plus miles on a daily driver and still fun to drive. All driveline is original and replacing the steering rack next week.
This was a very interesting video! Loads of information in a very well organized and thought out presentation! I have a 2001 Subaru 2.5rs and absolutely love it!
Finally the video I've been waiting for!
One quick note, the EJ255 in the 2010 up Legacy GT had also had dual AVCS.
Very informative, educational, and entertaining! I enjoyed the knowledge he shared on the EJ motor!
Hey man, love your videos! Ive been a subscriber now from a month or two I really love all of them especially, iconic engines. Tbh you really explain each engines very well out of the other youtubers i see out there, i hope you can make more videos of these and i wish you can make an RB series of nissan video. Keep it up man! Proud subscriber here! :)
555 for the classic cigarette livery on the rally cars ;)
2 weeks late, Damn. 😲
These subarus kids are living the future of the 555 22b somthing imoreza
firtdudecoolman PLAYER yikes butchered the crap out of that one * Subaru Impreza 22b. Also I’m 22 an have an 11 STI kids these days still love Subaru’s an know about the past we just have way better technology than you old farts when you were young
I'm 40 and in Australia we used to steal Mitsubishi GSR's and GC8 WRX's the police couldn't catch us n got so pissed off they ended up buying WRX's to try catch us.but when you're young and have a weapon car like that pol-air ain't even goin'ta catch up.Long live the EJ 20 turbo and Subaru Forester & Impreza WRX FOREVER💥💨🚀
@@mathewrobertson8975 lol, did you know that the early model WRX's where nicknamed "the stolen generation" by the cops?
For people not from Australia, "the stolen generation" is supposed to refer to aboriginal kids that were taken from their mothers at birth.
Wow. Some really good information here. I feel it should be noted that even though stock EJs can push 500 horsepower with stock internals, most Subaru vehicles transmissions can't take that kind of power. I know the 5mt is really stretched beyond 350 crank horsepower.
Even with stock engine the trans can.t take it,the v1,v2 have very weak transmissions,mine said bye bye 3rd gear
Late reply, the sti 6 speeds are extremely strong. They just don’t die, bader built for example has a stock sti gear box while pushing 1200whp through a ej25. With that said the 5 speeds don’t compare what so ever. 350-400 whp is usually as far as you would want to push it cause at that range your playing with fire.
Weak. The stock 2.3 Ford 4 cylinder block (the old one from 1974-early 2000s..not that 2.3 POS made now) regularly push over 600 and are used in certain classes of racing.
It's a pity many people dont know about rev match downshifts, it's a great way to keep the drivetrain healthy and improving laptimes. Yes, the mt5 isn't very strong, but strong enough if used the right way. Pulling the handbrake and slipping the clutch at starts, with revmatching downshifts and you need to be unlucky to break the transmission.
Usually i hear 350hp being safe and 400hp is pushing it on stock internals
Really good stuff man! These videos are killin' it.
Great video with lots of great info, got to love the subaru EJ motor. 555 for the classic cigarette livery on the rally cars. Thanks for sharing. Cheers
I have a 09 wrx making 550whp, everything he has said is very accurate, an experienced builder is b highly recommended, i recommend IAG, but like always mKe sure the person tuning has experience because even with forged rods and pistons knock with crack them, thank you for the vid
My god this channel is amazing! Can you make a video on current "Living Legend" engines that will one day be part of your Iconic engine series?
That's not a bad idea at all! Thanks. Will likely do something along those lines.
word! :) great video as usual, really enjoyed it (currently owned 7 out of 12 legendary engines from your videos, some multiple multiple times)
As you stated the the freestyle rap, “I’m not for beginners” I was going to answer your final edition quiz question but someone already answered. Thanks for clearing up lots of misconceptions.
“The trick is to buy them in bulk!”
The dealership (In America) actually give big discounts for buying in bulk.
I got 10 oil filters for like $3.50 each.
And dealer oil filters are important as the valve in the filter regulates how much oil bypasses.
So an aftermarket filter can totally cause your engine to fail.
@@fastinradfordable is your air filter oiled or not?
Thats new to me coz i used the K&N drop in filter for both my Crosstrek and Forester with zero issues. My intake pipe did break from wear and tear in my 10 year old Forester but overal it works well.
It prob those cheaper Ebay ones.
@@linchester8464 K&N make cool stickers, but overkill for most anything and they can have too high of flow even. Way too much, its like people who care about ralph lauren polos/.
Subaru oil filters are a must. My oil pressure gauge showed other oil filters 20 psi lower.
@NGT Alex me with 2002 legacy 2.0 n/a , original engine and ori gearbox still running good 200k km plus now..💪
I love these iconic engine videos ... very informative and entertaining! I don't know if you are still making these videos, but I would like to offer up a suggestion.... In the late 80's GM made a 3.8 L V6 ... sadly, I do not know the engine code, but I owned one and man was it a lot of fun! Very good low end torque and quite torque-y all the way through the band. Mine was in a 1988 Oldsmobile Delta 88 - (please don't judge me) - but I loved it and the pull it had and drove it to well over 200K miles. I also know that some versions were super charged... I believe the Pontiac Grand Prix was one such. I always wanted one of those, but it just never happened... Thanks again for all you do and BTW - looking forward to more on the Alfadan as you get it!
Ah the mighty 3.8 ecotec
Late 80s legacy turbo with gold&blue 555 and Tommy Makinen/ McRae among others got fame in the subs..
Great videos man, fantastic info. Thanks so much. 🇮🇪
This was an iconic video! Learnt a lot about my EJ255. Well done man!
One of the smartest videos ive ever seen
Thank you for setting the record straight on tuning EJs! They are fantastic engines and can be "bullet proof" when built correctly and maintained properly. You can't just slap the biggest turbo on them or dial the boost all the way up without proper tuning/reinforcements or you'll spend more time (and $$$) rebuilding the engines than enjoying them. IMO, boosted EJs are loads of fun and make a lot of power, so they are great for performance applications. But as a daily, I would take a NA for reliability and consistent performance 100% of the time.
The only engine type (boxer) that can send a basic symmetrical awd for a huge horsepower, with balance! Other engine will require a more demanding awd sytem.
did you see gears and gasoline "bullet proof" a low mileage sti just for it to blow up a week later?
understandable, but if you're running a lower power NA engine for more reliability, you may as well run a 2zz from Toyota. It's a fierce competitor in terms of reliability, it puts out 160-180hp NA, revs to 9k, and has VVT
you deal with the obvious issue of mating it to a RWD or drive train but considering 1zzs were mated to AWD trannys, I imagine a 2zz could be mated to a decent AWD trannys as well, just a thought
oh and did I mention they're quite easy to work on?
@@peanutbutterpadre1519 they took that motor apart and realize that it wasn't built properly.
@@TheJines123 that was the evo... the sti was factory stock and they were the ones that built it.
Hearing that we got 555 of the EJ20 Final Edition cars almost made me cry from the nostalgia.
Thank you so much! very useful info. It help me a lot to understand the subaru cars more that any info that I have before.
GREAT!
great vid man. having worked on heaps of TT Legacy's, i can straight up say that they aren't that bad. until you get to the black box of doom. this is where the TT black magic happens, and its a mess of solenoids and vac hoses. open one up and you'll have nightmares for weeks. Get a code 66? nightmares for months.
You are a really good story teller.
I like how you do deep research before making the videos
I've been awaiting this video for a long time! Thankyou for the great content! Keep up the great work sir
wonderful documentary for me perfect clean and clear
Please make a video on the EZ30, i know its not that popular in tuning community as the EJ/FA or any JDM engines but the engine itself its pretty good and have big tunning potential.
Enjoying this series.. Although, I am surprised that some performance beasts like the RB26/N54 aren't in the video lineup. Those engines respond amazingly well to tuning and modifcation.
They, together with many other engines are in the pipeline. I don't do these videos too often as they're extremely exhausting 😊
@@d4a you need a sponsor to motivate you to do more. These engine legend videos are great
lol what's a 2JZ, what's a 1UZ
Just bought a 2013 WRX two weeks ago.... I'm in love with the boxer engine.
That is really awesome! Thanks for a great informative video. Love it!
The "F" in FA and FB is friction, as in low friction engine. This is what was taught in Subaru tech training class.
Gotta admit the EJ had an extremely good run. Most engines don't have nearly a 3 decade lifespan. Surprisingly, the SR20 comes close, but only due to the SR20VET in the Nissan X-Trail.
The EJ managed to get praise from drivers and automotive journalists alike the entire time, and the last EJ cars are still being sold today. The S209 even sold for over its MSRP of $65,000.
Couple minor corrections. The S209 has an EJ25 and makes 341HP. The S208 had an EJ20 that made 325HP. So your max factory HP numbers were a bit off. Special editions though.
Lastly, the EJ20 in any form left stock and well maintained is one of the most reliable 90s/00s turbo engines, especially Phase I. That's a hill I'll die on. ;) Great episode man!
Sbc,bbc 50yr run.
Yeah, my 95 WRX is still going strong, well Engine is. Transmission on the other hand 😭. Just put in an 08 STI 6MT/Diff 😁. Not a direct fit as the forums would lead you to believe, but I made it happen none the less.
@@taomicioli I was looking for your response

Freaking love it man. Thanks for a great informative video.
Wow! A living encyclopedia of Subaru info! Impressive!
On the head gaskets, alot of performance companies have spent time and money in researching and developing newer stronger head gaskets.. love my 05 blobeye stock ej205 wrx
I have an 02 wrx that I still love after 15 years. Great cars
Just bought a 05 forester 2.5x 5 spd manual i absolutely love the powerband of the boxer engine in the AWD it just puts the power down heavy hitting torque and splid top end response as well.
Great video. Very interesting. I have been driving Subaru's since 1990. I had UK and JDM ones like the Legacy GTB with the twin or really bi turbo EJ20 engine.
Subaru has a efficient and awesome engine design and they refined and refined over decades, to the engines best version. Unlike other automakers that design a new engine from scratch, causing many problems and failures. A Subaru engine, with regular maintenance, can go 300k miles. Now that's reliability. I own a Subaru and did lots of research before buying. So, I know.
Yet so many people don't do that regual maintenance and it just destroys the engines. And they then get a bad wrap
Source? "Trust me bro I did lots of research, I know."
@@yamaccandan1 plenty of 300k subarus around lol isnt that proof. what is he suppose to? do a harvard study
@@SamBrunink i have never seen a turbo EJ subaru with over 230,000 kms and original motor. Now maybe its because the owners usually thrash them rather than the motor itself being bad but there are no 300k MILE subies where I live mate.
@@yamaccandan1 I've got a ej255 with 220k so far and it's extremely healthy yet minimal blowby. Did have a replacement turbo however most fail around 200k original clutch yet too
As someone who is EJ25 swapping a vw bug this was highly helpful. You earned my sub
I loved this video! Thanks for sharing it!
Pozdrav. No mention of the EJ22?!
We love you Subaru though you killed the turbo in the 2019 Forester 😟. Keeping making awesome cars. Don't get complacent.
Thanks sir for this video. It'd also be nice to know the history of the cherry blossom red color on the STi badge
aaron sempa the cherry blossom red color is matched to the trees outside on the first Subaru factory at the base of Mount Fuji. The trees blossom isn the spring and their flowers are the cherry blossom red you see on STI badges today.
I still can't believe they discontinued the 6 cylinder models. The 3.6 engines were by far my favorite.
@@josephwhite6047 yes, but that 2.4 is going to be a beast.
Expert knowledge, keeps you hooked. You know he’s good because he never do video edits.
Never was a Subaru fan I just heard of nightmares but after watching this video & the history I have a new found respect 😉 but I do remember growing up watching speed vision & those evos & STIs kicking ass rallying 👍👍
can you do a iconic engines on the 5.9l cummins?
PSA for Comment Readers: ANY Subaru turbo engine is not especially prone to head gasket failure. That is ONLY the NA EJ25 engine until 2010 and especially pre 2006. Read up, Watch MrSubaru1387, stop spreading misinformation. :)
All I worry about is the piston rings. In 2018 I think the STI pistons were forged and they came with better rings, but I'm not sure.
I have an EJ253 im not en engine nerd but ive been told its one of the engines that have this problem. is that right?
@@RedDread_ Unfortunately, yes. Less common in the 253 than the 251, but still happens. Do research on how best to prevent it. Mostly do regular maintenance, have your coolant changed every 40K miles and use the newer style blue coolant if you can. Also make sure your grounding is good and keep the surface of the battery clean. Basically you want to reduce any corrosion and electrolysis, plus prevent any chance of overheating.
@@stuna101a Yeah the STI ring lands are an issue. It definitely isn't every single engine, but it is prevalent, especially if you do some modding/tuning or experience knock. The 2018 RA pistons specifically are different I believe, and I think the 2019 and 2020 models used those pistons as well. Not 100% sure. The coolant reroute mod is popular for the EJ257 to help prevent high cylinder #4 temps.
On my 2000 EJ25, I've replaced the head gaskets twice. Back when I did the first change, It was recommended to use the subaru replacement "improved" single layer gasket. I used the Felpro? With no resurfacing other than scraping and cleaning. Needless to say, I only got 80k miles out of that repair? This time I used MLS gaskets and resurfaced the heads and block with 220 grit wet sand paper, a harbor freight body sanding block and some scotch brite.I shaved off about .010 +/- from the heads and got them to 0 warp. New bolts, new seals, new timing kit, new water pump and a set of G-Powers. I set the valve clearance at .004 and didn't look back. Runs better than It did when it was new. In 20 years, this is the only major work this car has needed. Luck? I don't know, Good car.
Great video ...fun and excellent detail, well done.
Legendary engine for sure ! So smooth love it ! Unlike any other car because of flat 4.
Owner of an ej206
One of the best Subaru videos on youtube, thank you! I have been saying this for many years about EJ engines, generally I write off people who talk smack about Subaru, usually no experience or as you say shit at tuning or builds, esp in the US.
One thing I would point out, New Zealand also got the EJ20 as well as Australia right through most generations, new eg NZDM & ADM..
In the Legacy it has always been the Legacy in NZ, Australia often has a different name on some models regardless of brand due to a brand registering that name, for example, the Toyota Highlander as in Japan and New Zealand is known as the Kruga in Australia because Hyundai registered the Highlander name before Toyota did in that market, not 100% sure if this was the same for the Liberty naming instead of Legacy in Aus, but pretty sure it’s the case. NZ esp has always been very loyal and while small compared to US and other markets is an important market for Subaru, again thanks to the US this has been somewhat eroded, US tends to screw everything for everyone eventually, they want what others have, then turn it into what they already have and like everything else, losing the special or uniqueness , so the special models have slowly disapered or become diluted to suit the American market of bigger and more is better, rather than unique, which was the dam reason we love them to being with, now we get more road going heritage rather than the rally heritage. Lucky here we can and do get true JDMs imported regularly independently to our market, not from individuals but our car dealer market is mostly Japanese imports for second had vehicles it’s massive here.
And all JDM manufacturers not just Subaru, so thanks America you ruin everything special in all brands non US manufactured even BMW have bowed to sell to the US market, don’t care about BMW anyways as long as they stay away from Subaru, unlike the A90, oh what that could have been if a true Supra. But Americans happy it has the BMW name brand and fancy shiny leather they all crave so much. Again not all Americans but watch any video from them and you see issues or heard of issues and the fake reliability perception, I see EVOs and other Nissan’s as much if not more, but rarely is it the cars fault. Like the vaping perception I hate that too and it’s BS, vaping is a disease if not worse than smoking and it’s eveywhere
.
But great video and having had over 20 models of Subis over the years and still GCs EJs today I still learnt something, appreciate the quality info and presentation awesome.
Quick
My experience I have had , 13 EJ20s, 1 EA Justy for the GF at the time, 2DLs 14 door (78), 1 2door 76) always regretted selling the 2 coupe, esp now as rare as. 2 Brats 78 and 82 (ute) Brumby in AUS, 2 H6s, 2gen Outback but first gen H6 engine, then an 08 H6 GT Wagon (NA) and that thing was awesome as fast as my GT-Bs (TT) .
The only models I have not owned but have driven a fair bit are the Forester, always wanted one, but never ended up in the garage yet.
The Tribeca I would never buy, hated that model, Subi went bad trying to again appeal to US again and why I hated it, it even looked un Subaru! The Levorg it’s grown on me. Anyways great vid and explanation of all things EJ best I have seen by a long shot. 🦄👍
Can you make a video on underrated engines like the 3RZ-FE, the 1FZ-FE and the TB48.... etc? 😁
Or any TDI?
great video, excellent detail thankyou, i learnt so much! i think i regret getting rid of my old quad cam now!!
would be interested to see a video on the audi 2.5L inline 5 cylinder, i think also had/has a long production
Finally man an engine from my daily beside aw11. Super video. Thanks man😀👍
That said i def missed my EJ20 powered Forester.
The EJ20 ran strong with a few bolt on mods. WRX turbo, bigger fuel pump, STi intercooler, STi injectors and the ECU Remap. Got like 250+ bhp from the stock 177bhp.
Ran like a champ for over 10 years with regular oil change and maintainance. But the gearbox was the major part that decided to fail. And it was a costly repair. So i have to scrap it.
Now I drive the newer FB16 power Subaru Crosstrek/XV.
The FA and FB are the direct successor of the EJ engines.
Heres hoping to see the FA20 powered WRX STi in a few years time.
We'll be getting an FA24 powered WRX STI next year. :)
FA24 for the win! Can't wait to see then immediately buy the new gen STI. Happy with my EJ25 while waiting.
@@802Garage sorry, there will be no other STi until the electric is fully developed, as per Subaru internal announcement.
@@ItsFritzDaCat Yeah and I'm well pissed. Moronic decision by Subaru IMO.
Thats really interesting about twin turbo only being in RHD cars. There's a similar issue with a lot of engine swaps in E30 BMWs. Many different engines will physically fit inside the engine bay, but they won't clear the brake booster. Many people just switch to a manual brake setup, but people have also come up with a lot of creative workarounds
Also want to mention it would be really awesome if you did a video on the BMW M30 engine. I believe it was the longest running engine ever made by BMW
its because those that drive on the left hand side cant handle the power.. and im not talking about the EU
Awesome Brother! Well done! I really enjoyed it! Thanks!
Great video ,my 2005 OUTBACK 286,000 STILL going strong in 16 years both front tie rods and brakes that's about it ,,still gets 30 hwy,with 3,000 miles on oil it's still clear on dipstick,this is a sign of well balanced engine the 2.5,,THANKS SUBARU!!
22:21 Yeah idk about 400 whp with injectors, exhaust, and an IC, with an ej25 coming at 300 stock you'd be good for 350-70 stable, 400 and your really pushing the limits, but just my 2c
These headgasket jokes are so 2004.
It’s 2020. We’ve moved onto *spun bearing* jokes now.
My rod bearing in cylinder three agrees.
I guess we are in 2004, then? Just changed the headgaskets on my 2006 Forester XT.
Dan Slotea Exactly. It’s an ‘06.
So that’s why my local dealer has 4 WRX 16/17/18 with buy it back lemons title? All cars has less than 40.000miles......was planning to buy it one but looks like still no good....
@@jnagime Subaru has the balls to back their flat world perspective, when Subaru makes a lemon.. I make lemonade. YuUp. lemonade is good with adm E85 a jdm ej20.. STI for L prices.. TY blue stars..
What a nice video!!! Tks a lot. Best regards from Brazil
Love the little rap at the end bro, gold 👌
Im awaiting delivery of my 2020 STI. Perfect timing for this video to make me feel better about buying a 25 year old glass cannon 4 cylinder gas guzzler.
I was looking to buy one this week but my local dealer had 4 16/17/18/19 with buy it back lemons titles,all cars has less than 30.000Miles I walked way.....
Rumble prevails
ya I cancelled the STI went for a 2019 WRX instead and I'm happy it gets great MPG
Is there a book kind of like a bible for tuners to build an EJ engine properly? Thanks, great vid!
Great question
We wish. We basically throw shit together. Ziptie it. Send it to the dyno and hope it comes back with all 4 pistons.
This is actually entertaining and informative
Video recommended at 2.40am... now 3.10am and feel like taking my 257 turbo for a rumble in my quiet neighbourhood... great stuff
I think the classic volkswagen beetle engines were also boxer engines. But maybe porsche had something to do with that.
They were indeed. Air cooled pushrod boxer engines.
The ej20 was great and reliable if left alone, the only issue was when adding power it was the piston rings that were the weak point, the engine would start burning oil. Other than that they were great.
Just got this issue with my ej205 burned oil like it was fuel, so now I'm getting new internals to be safe🙃
I had a 1993 subaru SVX or acylone. The H-6 in that thing was so rad
you answered all my questions bro 🤘🤘 thank u
“The E stands for Engine” confuses this FA20 owner.
Well, it could better mean that this isn't a completely Subaru engine. It's a product of the Subaru/Toyota joint venture with their sports coupes. Toyota provided the D4-S fueling system.
@@JoseRivera-ym3wj Think that went right over your head pal.
FA can be used to describe a car with (F)ront mount engine and (A)ll wheel drive. But probably a coincidence as brz/etc. is rwd
@@Lucas-dc3fs Yea. The true meaning confirmed by a Subaru engineer is FA stands for Fking Awesome engine.
The FA20 runs ring's around the EJ20.
EJ engines don’t have cast iron cylinder liners (13:47).
EJ22 from the turbo legacy did.
255 and 257 have for sure
Great video. Thank you for the video
My second or third time watching this and it gets better each time. Keep up the great work! If you're not tired of profiling iconic engines, I would love to see a segment on the Ford Cosworth BDA and/ or the Millington Diamond engine. I know that your exhaustive research would do these engines justice. Thanks for all that you do! :-).
Thank you for the kind words. There's a bit of cosworth BDA in the Toyota 4AGE video :)
I feel like the ej22 was more iconic than the 20 and the 25.
90% of EJ blow because oh crap tuners, not the engine
natesway34 well the stock ic can handle stock power, so if you’re tuning your car properly, upgraded top mount or a front mount should be one of your priority supporting mods if you’re going beyond stage 1. Too many people will just intake exhaust access port and push max boost, Hence 90% of EJ blow because of crap tuners
true,mine was working amazing until some mechanic in my area that claimed he is experienced mechanic spoiled it.. have to spend more money on ordering parts for rebuilding. took 6 months to get my GC8 wrx ver 5 back to the road.
natesway34 a AP won’t help your motor last longer. If you see something weird on the AP then Your already to late, you can’t give your engine a rest and it’ll just heal back up. Boxer 4 and 6 cylinders are just inherently weaker due to the design compared to inline or v block engines, And due to the way they are designed there’s no main caps on the crankshaft and with the timing components spread out so far you run into timing issues if you machine the heads or block.
I own a 2019 WRX and a 02 bug. Had a 05 blobeye. I’ve been in and out of these engines ALOT
natesway34 I think in reality the focus it takes to examine the AP and read the info displayed and make a conclusion is not something inherent to most ppl who drive sports cars. And when your driving (or “beating” on it) you can’t reliably watch the AP so you will have to use data logging and that’s after the fact.
I would say that the AP CAN help you see anomalies but unless you have the limits set to warn you, you’ll miss 90% of the anomalies that may happen.
For example a boost spike while you. Pulling away from a light, you most likely will not see this happen and may hit boost cut or lean out within seconds
natesway34 I would argue that it DOES mean it’s too late for the most part.
It may not be damaged but it’s definitely too late to prevent the anomaly because that’s how you found out about said anomaly when you see it on the AP. I just don’t agree that the AP will prevent anything. It’s all on the operator to constantly watch and review the data logs to know what’s happening
Loved the video and the information. Happy to say that I am the proud owner of a wrx sti with the ej25. Love the car but the stiffer suspension on Texas roads is almost too rough. My 3yo daughter loves the boost too.
I know its not reallt an iconic engine but honda h series I would love to see a video on. Great video as always
