Seeing people stating, "I'd rather have an Audi" or, "I'd rather have a Porsche" proves that the mechanical build quality of a Subaru is at a high enough level to even be compared to luxury
+Jason Papa german cars is where its at if you want superb mechanical quality
+Jason Papa Anyone who says "I'd rather have a Porsche than a Subaru" is an idiot. Not because there's anything wrong with Porsche, but the price gap and targeted audience is so different. That's like going to an ice cream parlor saying "eh, I'd rather have steak".
+Peter Schmidt great point and explanation
+Jason Papa In a perfect world I'd like to have both a 63 Impala set up exactly like how my father had his in his drag racing days AND a Subaru STI. But if I had to choose only one, it'd be the Impala. Simply because of sentimental value. Personally, I don't see why you would want something so expensive as a Porsche. Sure, it's fast and looks nice. But for the same amount of money or less you can build a car that is just as fast or faster.
Dakota Newcombe if you have porsche money why would you buy less?
you actually get what you pay for,
You can make a faster car than the porsche but the packaging, the style, the reliability and so much more is just why you should go porsche.
Cars just speak for themselves and different people want to appeal to likeminded people.
Cruising down the road with your 750 hp supra?
supra guys will connect in an instant.
Fast cars are all alike in that matter.
But if you make big bucks and you want to get to other ppl who can ball like you, a more expensive car will show this.
Tl DR.
You get what you pay for, and cars are a statussymbol aswell as a tool to go fast.
I just took apart my 2009 Subaru Forester. Machined the heads, replaced all the gaskets, timing belt, spark plugs & wires, timing belt, water pump, and did the valve adjustments. It was an amazing journey. Can’t wait to drive this car another 100k miles.
no space to work with, hard to change parts....
You had to do all that at 100k ?
@@johntesh199 at about 170k. I bought it from my neighbor and the gaskets were leaking bad. I meant to say that after all the repairs it should drive another 100k

Subaru has got to be one of the most transparent car manufacturer out there
When I was a teenager I really wanted a Subaru WRX STI, a 2004-2005 model. Maybe someday when I can afford it I'll buy a used one and have it restored. I know it's not some exotic European sports car or a badass muscle car, and those are all cool, but when I saw the STI after it first came to the US I just thought it was the coolest cars I ever saw. The coolest thing about it is the sound. That distinctive deep rumble they make, when you hear one you know exactly what it is.
oh and the fact they can go from 0-60 in like 4.9 seconds (which was faster than the standard Vette at the time)
Did you ever get the car?? I would love to know if you did!!
European sports cars are cramped and impractical. Tune a scoob and you’ll be keeping up with the sports cars and you’ll be significantly more comfortable and have much more money in your wallet (until summit blows up on ya)
2020.. have it yet?
p/s: i'm driving a 2004 sti for 8 years now
I wanted a WRX since I was in grade school. After 15 years later, I still want one.
Nice to see they aren't using rubber bands any more for their timing. Still VW made the first opposed engines for mass production in cars. Would have been nice for subaru to acknowledge their contribution.
Drinking Jäger + learning about Subaru's engine might be my new routine on Tuesday nights.
all the people hating don't have a subaru
@tponn or have an Audi and laugh at the vapers in kids cars.
漂亮
ryan leggo yes
Well yeah obviously they don’t have one because they hate it
there 2 options, or you don't have a subaru boxer or you don't have the 4th cylinder
Subaru's excellence is not just with their engines. The seats in the 2004 Forester XT (turbo) were more comfortable than those in the Chrysler 300 & Volvo S60.
I moved to Japan and purchased a 2011 Subaru Impreza 1.5 5MT with 88,000 km. It's not fast but the AWD system is awesome.
A very good design. Been working as mechanic for 33 years and I've always liked this concept. VW introduced me to this.
always wanted to be a mechanic, maybe one day ill buy a bug since they're basically the pb&j of project cars and easy to fix haha!
Im a mechanic and never seen a single subaru come roll in of my 5 years of working as a mechanic. I own a brz and i love it 150,000 miles and still running like a champ.
I wish more car manufacturers will offer boxer engine cars. They're so smooth when driving.
a lot of them used to. the VW Beetle had a boxer 4 cylinder and was legendary not just because it was efficient, but also pretty reliable and easy to work on.
Porsche still uses boxer engines in the 911
Going on 9 years later this video is amazing. Super fascinating and informative.
Whoever edited and published this content did a great job. Tight work. Have a
super time in the land of the living. Later ✌🏾
I love my 2011 wrx sti, I baby it every single day! It's left completely stock, and I enjoy every second of it...stock! The way it was meant to be enjoyed!
yeah i hate ricers too.
This was the most creepy and informative video I've seen.
121k miles on my 2001 wrx, its been running 320bhp (with sti turbo,injectors,fuel pump,remap)since 49k, had no engine problems at all.. just regular maintenance costs
own a 2001 Forester...when I turn the key, the car sort of "seizes up" then when it starts, it "relaxes"....love that feeling. Great cars
Best description. Totally agree.
The Subaru engine has a lower center of gravity than the fords. I also don't think horsepower is the main factor in such a small engine since they get turbo charged a lot. I do like ford but I've never had issues with any subaru I've owned. Each exceeding 250km. Maybe it always just comes down to how you maintain your car.
Great engine. Fun cars to drive. There were a few years where the head gaskets would go. I look for those to buy them cheap. After replacing a few it takes about 5 hours in the driveway. Can't think of a better way to spend a Saturday! The last two I've bought have not had issues yet. They are a fun funky car to drive.
So many misinformed comments here about the "boxer rumble", which is NOT caused by a boxer engine design etc, but by the unequal length headers which causes exhaust pulses to collide and cause that "rumble.
The newer FA20 engines (2015-WRX) have equal length headers and the "rumble" is gone. Therefore, it is not caused by a boxer engine.
Just like a Porsche never had a rumble, newer and better flat fours from Subaru also do not. STI's still have it because they have been using the EJ25 engine in them for over a decade.
I'm sure soon (2018?) that will also be gone, they need direct injected technology and better tune /exhaust etc so to compete w/ 350+ HP Fords etc... My 2015 WRX runs like a champ but only after using a better tune, the factory tune is total crap!!!!!!
Thank you for your competent comment on this.
For me, the only thing that could be a critic point on flat engines are the gasket problems that, always, take much time and effort to be solved.
But it is not stopping me to look out for a 3.0R flat 6 engine (not that much of those were sold in Switzerland).
not to mention the fact that the WRX is supposed to have rumble since it's a damn sports car.
Even then not subarus have ULH.
My SVX engine also doesn't have the Subaru Rumble. Equal length headers as well.
Is it possible, or even good, to have UEL headers in a FA???
love my H6! smooth, powerful and sounds great.

The engines have a nice lifespan... I remember watching some other video stating that subaru cars have the longest average ownership cycle. Something like 14 or 15 years. But yes they effects of having that particular setup of the cylinders is questionable. Then again 40+ years of development may have gotten over any hindrances
OMG!! Now I know why my very close friend the one that study with me back in the college but he's take diploma automotive technology coursed, loved subaru so much. Thank you for this informational video ❤️
Always loved the boxer Engine, my first car was a 92 loyale 4x4..
been with subarus Since.. now i am a subaru backyard Mechanic.
I was wondering how these engines worked. I was always confused looking under the hood of a subaru but this breaks it down for me. Thanks!
I had a 16' Forester with a CVT and loved it. The problem was the huge bills to service it. And, when I saw how complicated the engine was, it was the end for me. I am 72 and can not afford a big breakdown. I tried to buy all the warranties available to make sure that was all covered, but ... their greed lost them a customer. This was in Portland, Oregon.
find someone who can work on Subaru engines well
Hello from 2023 my 2012 Impreza has never let me down and I’ll be a buyer til I die
The "Boxer"air-cooled engine was first developed in 1885 by Karl Benz. Benz received a patent for the engine 1886. it was aplied to motor cycles and quite extensively in the Volkswagon. Over the years VW stopped using the boxer engine and went water cooled. Subaru obtained the rights to the engine and over the years Subaru engineers converted to what it is today
Other than replacing the spark plugs, they aren't that much different to replace regular items like pulleys, belts, alternators, batteries, etc. The exhaust layout on the turbos is a huge headache, but otherwise my wrx has been as easy to maintain as any other 4cylinder I've owned. 120k miles and still going relatively strong.
Got myself a Baja. Awesome car.
My 7 year old requested we look for a vid of the Subaru engine and…. here we are. Great video!
its an amazing boxer engine its really good
Came for information, left hating mimes more than ever.
Absolutely - that mime just slows everything down and adds no value to an exposition that I'm deeply interested in
@@catnipyfy cause when you think cars...you think mimes
irony of this comment is your pfp
I had a used Subaru FF-1 1100 said to be a 1970 model though Interestingly, I have seen a 1968 model on youtube that looks identical down to the color of the red water pump pulley and enameled green valve covers, inboard drum brakes, the whole 9 yards. It had high miles when i got it in '74 or '75 too but always gave great gas mileage @ 40+MPG. I had it 13 yrs and even did a light engine rebuild in 1980 which lasted well! I wish I had gotten it new and still could buy such a car today!
As an audi owner and a subaru owner. The 2.5 liter sounds amazing.
I'm all up for boxer engines (own an fr-s), but what Subaru is doing with cutting down the manual transmission option in most models... is sad. The CVT just does not go hand in hand with the all good stuff that boxer engines can do when paired with manuals. CVT is probably the most numbing thing auto industry came up with.
Preach it! Stick shift forever!
That's true
NemanjaGuitar Completely disagree. I had a 2010 outback and just got a 2015. I am amazed at the changes in those five years. the 2015 is a completely different car. advanced CVT, which i loved in my 10 and in the 15. The ride is better, as is handling. The electronics are fantastic. I simply could not be happier. Manual transmissions are for kids. I am not a casual driver, just one who enjoys riding and driving a very nice, solid and safe car. What more could one ask for.
amesburydory A solid, nice, safe car could be absolutely any modern car with a few exceptions. Saying your satisfied doesn't make it OK to remove options others enjoy, especially on the sportier cars. Saying "manual is for kids" isn't a good argument for removing manuals. For me for example, it's being in control of the engine. If anything, it let's you be more responsible for your own fuel economy, speed, etc. Other than the "show off" element I'm not sure why manual is "for kids". I've driven a manual my whole life, good luck finding a car here that isn't one.
Love the high torque cvt in my 2015 Legacy 3.6r. You're misinformed
Please let us not forget that even though the boxer is a nice engine, however it is SUCH a bitch to work on. HEAD GASKETS! HEAD GASKETS! HEAD GASKETS! I know a subaru tech that works at my local dealer, they have 4-8 a month in the shop, all head gaskets. A dealer charges $2k - $6k depending on if its both heads and if its done right by REMOVING the whole engine. I currently am saving for a wrx sti, I love subaru, but the only thing selling me on them is their AWD, else mitsubishi would have my money, its just that where i live AWD is a must. Currently im driving an inline 6, and yes its not a fast, racing engine, by all means, and yes the center of gravity is off, but i will tell you, when I am working on my 2000 cherokee, it is a DREAM to work on, and it is both inexpensive and can be done easily at home.
Chase Null If you make a pulley system in a garage and you don't have a motor pull then you can do headgaskets, or just buy a pulley and do it safer. Not to mention having something to allow you to pull motors will help in the future.
Connor Keegan funny my straight six doesn't need an engine life, I could literally sit inside the house of my car and work on it.
Well that didn't make sense. I agree that boxer motors are a bitch to work on, I was just saying it's cheaper to get a motor pulley and be able to pull them and fix the headgasket yourself if you're mechanically inclined. I also know that it's easier to pull the head on an inline four, a straight six, and most other motors that don't actually require you pulling out the entire motor. I'm pretty sure you can also drop the entire front suspension on my 96 impreza outback to get enough room to pull off the heads but it's a tight fit to be working on it like that.
+Chase Null I recently pulled the engine out of my sti, had it rebuilt and put it back in. It was a total breeze, and before that all I had ever done was change break pads and oil...Subaru engines are really easy to work on, but the horizontally apposed design makes the weak head gaskets hard to work on, you can do them in the car, but it is a pain.
***** sorry you had to do that. seems like a lot of work for a newer car. I say newer since I have never had to do it on my 2000 cherokee
aw man, i love them. the sound, the simplicity, i for one wish it will live on and improve.
Rotary engines are bad ass!
cool. I just bought a brand new 0 mile replacement OEM motor for my 06' Subaru STi and I am glad to see how well it was built. I cant wait to run it... I added 18GXT turbo, JE forged pistons and more
I love the sound of the engine!!!
god bless subaru best cars in the whole universe
+Kirill Kravchuk Boy do I feel sorry for you. try a chevy small block at 7500 rpm; you'll need a clean pair of short's after that ! piss on Subaru !

i love the shitwars you guys start they entertain me
their on par with ford, both are really great cars
2 car videos later and here i am. It was quite informative. But trippy at the same time
That's why I love my '14 Forester!
A great engine design! I loved my scooby! There are question marks over longevity with the design but they are so well built they deserve a new head or engine rebuild every 100k or so
Subaru boxers generally run fine for 300k + just keep it stock even the 2.0 turbos, a new head gasket and timing belt is always welcome around 130k miles just like every other 4 cylinder vehicle
@@jakefearing6640 how about adding straight exhaust pipe? Is that interfering with stock?
@@erickforester6450 im not 100% sure but a cat back straight pipe wont affect the longevity of your boxer
heck my alternator belt snapped at around 120,000 miles in my 2010 Outback.
Used to own an Sti. WHAT A CAR
This might be my favorite video ever.
Own a 2019 Subaru Ascent. Smooth, quiet and extremely comfortable ride. All of my passengers still comment today in 2023. Very roomy, tons of safety features this SUV humms at 85mph on-going no problem. The air conditioning system is bar none the best. Maintenance costs are very reasonable. You won't even hit a large maintenance bill until 60k miles. Cost is around $745 but they do a lot on the vehicle and then, other than my free oil changes at the dealer, my next expense is minimal at 90k miles. What is nice about the boxer, 4 cylinder turbo engine is that if needed, you have a tremendous amount of power starting at just 2000 rpm! Punch it and go if needed.
This is a weird ass video
Thank you!
Surely it was made by a japanese guy and then translated to english.
haha yeah
that meme and animal comparison is just weird!

Super car for winter drive!!!!!!
After considering Subaru for some time. Finally got a 2016 Outback prem. My goodness what a driving contrast from the old Silverado..The doors seal so tightly. You feel a pressure change when shut. Or so it seems. I have heard from many, with care those engines. Can just wave at 100 k if properly cared for. I would defer to a pro on that. Until then. Enjoying the vehicle. Oh. And Who Dey Go Bengals
Just took the MY18 XV for a test drive, I was so impressed with it. I put a deposit down on a 2.0i-S , should arrive in a week or so. Ca'nt wait
You know what I love about the boxer engine? When it does a head gasket at 100,000kms (common issue from 03-07) the whole motor has to come out because you cant reach the heads. Best. Idea. Ever.
Last year for headgasket issues in the US was 1999 when the EJ25D was phased out. The 251/253 rarely has issues, and is almost always maintenance related.
In Australia the 2.5 was notorious for doing it passenger side around 100,000kms. Even the tech said that it was something that they 'fixed' from 2007 onwards. 3 cars I know of were all meticulously maintained, 2 Foresters and 1 Liberty. If you were lucky it happened before the 100,000km service, if not (like me) it was 3,000kms after it had just been in for it's $1800 100,000kms service.
It has always been and will always be a common issue with H engines.
@@JyroOne not really. Just find the right mechanic.
They solved that issue and they are reliable again
Don't like subarus but I think flat four engines make the COOLEST noises.
Sorry to say but that noise that everybody loved in the 2.5 is no longer present in the 2.0 fb20 engine..... headers got equalized to increase efficiency
tim michelson How big is the market going to be for unequal length extractors for these things u reckon? :) I just picked up one of the last 2.5L WRX's at a bargain price in Oz, must have the rumble!
Now I know what it means Boxer-engine and why the Toyota wants Subaru engine for its FR-S. Nice video.
in 1970 I owned my first L15. In 1972 I owned my first Big15, later powered with a D motor and gearbox that stunned passengers: especially after avoiding our fatal accident due to the Citroen's amazing abilities. Then my ID and DS's. My personal claim is merely confidence in my cars ability while testing its limits. In 1980 I married at 30 years of age, with a promise that my wife would never question my love of motor bikes and cars. Occasionally her friends poison her re this but I seem to survive.
I bought my first Subaru in 1980, a yellow Leone as my Citroen mechanic failed my needs when I needed him most. What a car! The pluses far exceeded the negatives -like hydromatic suspension- by so much. What a drivers car it was! My policy was to replace No1 car every 2nd year and my wife had the alternative choice. I discovered that her choice was of low quality engineering but high in creature comfort, while I chose a high quality car with low creature comforts at the same cost. This has since changed. Our 1999 Leone was a nightmare; motor out 3 times in the first 5 months and frankly it was crapx10. We gave it to a friend 2 years later free of $$ and he gave it away within 2 years as well! However, I bought the new Legacy which was magnificent. I have owned variances of this since with a big smile. I have recently converted 4 workmates to Subaru ownership after my enthusiastic demos as it is a drivers car, not a Ho-Hum car. Sadly, my Subaru's of the last 10 years have become Toyota's with a good motor and that annoys s me. Are the owners trying to become common car suppliers? If so, this article becomes obsolete! Top Gear were so in love with Subaru that it banned them from their show as little else compared, yet Subaru are reducing their cars to Toyota quality that makes me want to hang on to my older Subaru's rather than like my wife's later Subaru mediocrity. Do they care? I doubt it. But I do and so should you. Thanks, John
difficult to repair yourself, otherwise...fucking good engine.
Mine is incredibly easy to work on.
it gets annoying needed to lift the motor out if you want to do any work to valves or gaskets. Alternator is a dream tho
+nukeboy27 I did the valve cover gaskets without lifting it out, never needed to go further into the motor.

learn about head gasket failures, spun rod bearings, and blown piston rings.
Don't forget about broken timing belt tensioners and bent valves. Seriously, how hard is it to build a non interference engine?
Justin Stearns No engine is perfect. It's just a matter of maintenance. They made a 4 cylinder that makes you believe you're behind a V8. It sounds great with the turbo or blower, it's faster than the average sedan. Just enjoy it for what it is. As long as there are moving parts in a machine, failures are inevitable.
Yes, but most companies would go back and work the bugs out, they're still making the same engine (the 2.5L) with most of the same problems it had from the start.
Justin Stearns True.
+Justin Stearns the new WRX's and Foresters have the new FA20's. We shall see how they perform in the long run
Love my subaru can't wait to geek out on this fine machine.
I have a 2012 black with red trim WRX STI and I love it...
They should have headgasket r/r procedures in the owners manual.
or you can find the right mechanic
I'm a Japanese. In my country subaru is really a uncommon car maker. It's said there are 3 big disadvantages on boxer engine.
1. The pistons are lying down and they certainly have their weight, so they scratch the lower half part of cylinders, which makes the life span shorter.
2. The number of parts is 1.5 times of in line or v form engine, which makes it heavy.
3. Difficult to maintain and fix.
Why subaru doesn't develop an other engine? Because they are too tiny to develop another. If boxer is better than others, why other companies don't use it? Actually Ferrari was using it until 60's, but they stopped due to those disadvantages.
You're a japanese and yet you use a Chinese name......very japanese........
Aoru Not everyone use their real name on SNS.
LIANG XU and also vw, alfa romeo.
Poesche has been using boxer engines for 911 and Boxster/Cayman for decades.
Porsche still uses flat engines.
The spark plugs are easily accessed without dropping the engine. It's just a lot more work than an inline. You just have to remove the intake on the passenger side and batter+wiper tank on driver side.
Thank you so much for this fantastic video :)
Haha evo better than sti? That's why the sti beat the evo around the top gear test track huh. EVO's used to be awesome, but subaru has surpassed it through the years. Mitsubishi almost even discontinued the EVO series. Not to mention the new evo is gonna be a hybrid, have fun with your RC cars mitsubishi lovers, haha.
Ace Campano You realize your bitching at other people on the internet over car make when all that fucking matters is you like what you drive.
Get a life.
The Evo is actually going to be nonexistent soon, I'm sure you know,
Ахахахахахаха,you sure about this ? I have watched EVO and STI on rallys and eaven 1 driver wanted to compete with them both,to see who is the better! EVO turned out to be 3 seconds ahead of the STI,i am an STI lover and i am a big fan,but that fact is bothering me,so don't be so cocky that the STI is better than the EVO.. I hop[e in near future the STI can make a better model than the EVO to beat it :)
Randall Peralta As much of a Subaru fan I am, it's sad to see the end of the rivalry. (well...the future of it)
Subaru built more boxers then any other company? 11 million boxer engines. VW built over 21 million air-cooled beetles. They all had boxer engines in them.
+VolkswagenVMan That's a five year old documentary. These days they are building 1 million a year. Indiana plant alone is building 30k engines a month
+VolkswagenVMan I think they meant they are producing more of them at present than any other company, which really isn't a great achievement since only one other company builds them (Porsche).
Maestro_T
in cars yes, but Continental and Lycoming use the same design in aircraft engines. In fact most smaller piston aircraft use horizontally opposed designs. They almost never use any other engine configuratin in 4 and 6 cylinder applications. They go from flat 6 to radial engine if they need more power.
Y10Q I'm sure Subaru is producing more engines than they are too.
This video lies in more ways than one and it is a shame, because Subaru does make a very good car. Owner satisfaction has been high since it was first made in Sweden. And don't forget the Harley Davidson XA motorcycle made in the 1940s it had a opposed two cylinder flat engine. And the Chevrolet Corvair, 6 cylinder flat air cooled engine,made in the 60s. Ralph Nader made it look bad. Even BMW has been making flat engines since the 30s, in their motorcycles.
My Brother traded his 98 subaru impreza with 280000 miles on it for a new wrx and the dealership gave him 4k on the trade in which was impressive! the motor had a timing belt change and basic maintenance and tune ups done on time! car had no problems!! so im guessing the new 3rd gen is really good! i drive a 2012 wrx with an ej25 and i love it!!
i ABSOLUTELY ADORE my L.L.BEAN EDITION 3.0.. i think I'm the second owner.. it has 226,000 miles.. i bought it having195,000 miles.. I only had to replace the alternator, valve cover gaskets... it always starts well..& it REALLY FAST!! But i must also only use premium fuel only... it's 2002 model year... I'll ALWAYS BUY SUBARU....
Interesting video. What about blown head gaskets?
Last a problem in the '99 model year for select models equipped with the EJ25D engine.
The replacement EJ251/253 rarely has headgasket issues, unless maintenance is not followed.
independentmotors.net/subaru-head-gasket-replacement/
FCFordLord i have an ej251 and the head gasket issues were fixed in 2010-2011 for those (2004 impreza 2.5 ts) because I blew 2 of them before that was fixed.
The EJ25's were the only ones that had this issue. This was fixed when the replaced their head gaskets with multilayer steel gaskets. Which is where the (they must be machined on replacement) heads. The EJ22 and EJ18 used a graphite design that filled in imperfections. But while they used this as well for the early EJ25, because it was machined out of the same block design. This left less surface area for the graphite compound to fill, and allowed for head gasket failure. Replacing it with a MLS head gasket allowed to have a strong bond (because graphite isn't that strong inherently, and will erode.) This allowed the issue to be fixed. For a long term fix, they added a additive to the list for service with coolant replacement. Subaru's Coolant Conditioner, which actually has a micro-filler to prevent premature failure, but filling in the imperfections that may happen while the engine is hot or the head starts to warp, which looks to be based on a graphite compound. (not sure what it is.) I have a EJ22 that I just replaced the headgasket on personally. It only has a Graphite compound gasket. Works great for that. Not that I had to replace it, but because I was doing other work, I did.

Low CG, okay if the engine was laying on the ground, but the engine sits up high in the car. So out of the window goes that advantage. Since the engine is wide, the suspension arms are short and there's not much room for shock absorbers and steering parts.
These issues can be resolved if the engine was placed in a different position (like the other manufacturer does), where a different type of suspension can be used, and with the extra available space, the engine size/displacement can even be increased.
Boxers are very popular in small airplanes, since nothing has to be built around the outside, other than a cowl.
There's more than 2 companies that produce boxer engined road vehicles. Besides Subaru, there's also Porsche, RUF and BMW.
2stroke4me I think it has it's advantage for off reading vehicles. you can place the engine higher off the ground without having the engine cover the driver's line of sight.
How much lower than the transmission input shaft would you have them mount the crank shaft?
How wide is an inline or V transverse engine and transmission compared with the boxer with the clutch behind instead of alongside it?
How do you like your torque steer?
people make fun of subaru head gaskets but everything else about the engine is superior in technology 🤤
So their boxer engine not only delight the owners with their exceptional performance. It is also a mechanics' delight too cos they get to work on it every 3 years or so replacing the valve gaskets.
I've had zero issues with valve gaskets and have had my car, which is from 2003 btw, for 4 years.
Dominic Fong the gaskets from the turbo models are much better as they are different design
I don't think low CG and compact size outweigh the downsides of many extra parts, heads facing wheel wells making it harder to work on and I would have to disagree on boxers being quieter than other engines. When it comes to piston engines, inline is the simplest arrangement. It is a shame no one makes a inline 6 anymore. And a fast revving inline 4 would have suited the scion FRS better than the boxer.
+RCPro Driver My BMW 130i has an inline 6 as many BMWs: M135, M235, 335i... And BMW keeps upgrading its legendary inline 6 with new technology...
+RCPro Driver to my knowledge, the additional parts in any horizontal engine don't really ever fail. Obviously they *can* fail, but normally the common mechanical problems with horizontal engines has to do with oil.
I get the impression I-6 engines are just too awkwardly shaped to put them in modern cars. I don't think their size is the problem, they're just so long. Due to safety regulations and demand for more desirable features, it just makes more sense to go for a V6 instead. Brands like BWM and Jaguar likely will never abandon I-6 engines because that's what they're really known for, so they'll do what they can to make them fit.
Peter Schmidt if you drive a inline 6 you will know why they stick to it... It is long, and in fact it helps achieving a great weigth distribution... Add a twin turbo to it and it will beat most v6 out there and still keep perfect ressonance
+RCPro Driver The FRS is heavy as balls, that thing needs a 5L V8 at least. Or a turbo V6. Unless you throw some seats out or something, it needs some serious liters, or high-strung tuning.
cybertree I agree. how it weighs more than my scion XB is beyond me. Stupid lobbyist for the auto companies getting laws passed that make it impossible for them to build cars that weigh 2,000 pounds...which is about what a small RWD hatch should weigh. The days of "light" hot hatches and RWD coupes are gone. As are the days of straight 6's...which IMO are better than any V6.
Looks like Japan does have better enginners than US! They come to school here and return after they graduate. Why can't we keep some more of these smart guys here!
While tuned cars may have reliability issues, a stock STI or WRX are pretty reliable. Mine has been as reliable as a non-turbo so far. Nearly any car that is heavily modified will have reliability issues and need more parts replaced as the car is being stressed more and usually the driver is pushing the car harder.
The mime was scary. Those cars are a poor man's Porsche only with the engine in the correct spot (Top Gear reference, lol). I love Subaru's, lovely cars! The only issue about them is when the head gasket goes out. Just like on any car eventually, you'll need to remove the block to do the job because the inner fender walls are right up against the valve covers and heads. Every car has it's quirks so don't shy away from them just because of that. You can't call yourself a car guy until you drive a car with one of these engines and a Subaru is a wise and adorable choice. If your really worried about the head gasket buy something with the 2.2 rather than the 2.5. That's still a great engine.
find a good mechanic
Subaru is garbage. They are putting trash into a can and calling it a car.
Gordon is right. Find a goods mechanic. Oooooo all wheel drive. Doesn’t matter if the car doesn’t go any where. Parts a stupidly exspensive. 400$ for oem cv axle a piece. Come on. I had to replace mine at 65k. Bull crap.
Ej25* which is what the sti uses(ej257), and its the only car still produced with it. Its trash but the ej20s,ej22s, FA20, ez30 and ez36 are great engines. The diesel boxer was unique and an innovation but somewhat incomplete.... Because it still had many problems
I bought an Outback with 3.6 engine.
Loving it !
mar1video until it starts drinking oil.
Question for Subaru engineers. I just did my timing belt replacement service on a EJ20T. Why a belt instead of a series of steel gears which would be more reliable?
Edit: For example, Cummins diesel ISB timing gears
A series of steel gears for the Timing? = +Weight, +More Rotating Mass, +More Expensive... Hope this clears out why Belt is = Cheaper, Lighter and Has better Performance.
skirmish is partially right but he also forgot to add that the advancement/ delay of timing is in the case of the timing compartment on DOHC engines. Putting in a gear drive would make it harder to to develop the system. Our cummins 8.3l ISC has about 950lb of torque but 325 hp where as the subaru 2l has 265 hp and 250ish of torque. Diesel engines produce lumps of torque but little hp thus a subaru belt system wouldnt be able to cope. Besides a timing belt is like $140 + 1hr time to change on subarus but cummins gears are expensive and a pain to remove.
tim michelson
But how often do you remove gears? Practically never.
how do you make vvt system with a gear train??? Lets not forget this is a 300lb engine we are talking about, not 3000lbs of steel like cummins
@@skirmich Studebaker sixes and V8s used steel helical cut gears to drive the cam. Come to think of it, the Chevy stovebolt used gear drive.
The rings push harder against the walls than gravity so it's not going to wear the side closest to the ground more. Subaru engines are capable of 200k+ miles when properly maintained. Because of the layout they actually are less likely the blow up when oil starved as my ex ran her 93 impreza almost 30 miles with a cracked oil pan. Horrible noices went away after we fixed the pan and added oil. Drove it for another 2 years and then sold it :) No oil consumption or smoking. Amazing!
Yeah Alfa also used boxer engine too.
cool video
thanks
This ad is for people who like cars, but pay a shop to work on them every time.
duh
No need for name calling children. Subaru... They're one of the best bangs for your buck. They simply out perform pretty much most any other vehicle in their class, especially the Outback and Forrester for off-roading. Perhaps some of the other vehicles mentioned in the comments may out perform some of the Subaru models in some areas, but overall it's hard for most other vehicles in the same class to out perform them. Just take in account what you're expecting from your vehicle, cost etc. For all around true AWD vehicle they're hard to beat... Sales, owner reviews and satisfaction, road test (both real world in the field and factory) their proven history and just the facts ma'am speaks for itself. They may not win any NASCAR races or out perform a Jeep Rubicon, but they're a good solid vehicle. From a former Toyota 4Runner and new Outback owner.
Lol 4g63 destroys it u fool
word
Best comment here…..Subarus are one of the best
Thanks, really good video with deep information.
Gravity does not play a major roll in piston movement because of the presence of lubricant between the pistons and the bore wall. At high speed, the viscosity of the lubricant is enough to separate the piston and the wall in that tiny clearance between them. EXCEPT during major vibrations, when you have more forces than just gravity, you may have piston knocking on the wall, but that happens with every type of IC engines.
good luck changing the spark plugs on the boxer engine
+CaptainD00M It's not too hard to do :p
muchzshroom you need tiny hands
+CaptainD00M japanese have tiny hands :D
+G. I'm not Japanese and I have small hands.
Passenger side has nothing at all in the way with tons of access. Drivers side; unbolt washer fluid tank, set on battery or strut tower, tons of room.
Just did it yesterday, including gapping plugs and all, maybe 15 minute job.
I like subarus alot but the boxer is a bitch to work on
Why? I was quoted $1,100 to replace a cam belt in one car. I questioned CZcams and easily replaced 2 cam-belts on my 2 Subaru's in less than 3 hours for $126 parts! After my bikes, they are a dream to get at.
Mine is very easy to work on. Much easier than inline 4 cars.
Actually, I got the 3 hours wrong as it was 45 mins each. I must have smelled too much petrol that night. I have heard silly comments like the top side of cylinders getting no oil. Sigh, silly comments from those that have no idea how they work or easy they are to work on.
wait till you have to replace the head gaskets.......
Compared to my 1966 Triumph herald that I can replace a head gasket in 1/2 hour, the Subaru is substantially harder: ie, remove cam-belts, 45 mins to off and on and add each head off/on at 1/2 hour per side. But, while the Herald removal is a common need, the Subaru is seldom. I have just bought a 17 y/o 2.4Ltr Leather trimmed Outback at 461,893Kms with a workshop history. Nothing but regular maintenance! No turbo: the 2nd owner of just 6 months handed it to me with the comment that I'd -a Subaru fan- understand its idiosyncrasies. This car pulls like a GE loco. It can surprise some that want a traffic light drag. What I am replying to is the time needed to replace a head gasket: And that time is nothing compared to the output of a perfect motor. If you do not understand power to cost ratio, you do not deserve to own a Subaru. Buy a Nissan. Why did Jeremy Clarkson ban Subaru from Top-Gear? Because, to endorse it meant scrapping every other brand they could test. The cost to repair a Subaru is a lot less than competitors with the same H.P. output and that is my comment; Subaru offer us common owners a cheap, powerful car. It's maintenance is cheap for a non lazy person. But if you are Lazy, it is still a great car until you are stupid and make silly comments on CZcams expecting 600HP with no cost. I have problems with owners that want power and will not accept the associated costs.
I had to watch this video in orientation last week.
1:28 Inline fours typically have cylinders one and four on the upstroke while two and three are on the downstroke instead of pairing one-three and two-four as shown in this animation.
"environment-riendly design" ... 8:25
it is a nightmare for maintenance because of head positions... on other cars you just pop the hood and you start working on the engine but here you have to disassemble entire engine before you even start... so for users this marketing story can be interesting but if you are a DIY guy, just stay away from boxer engines... and he mentioned several times "many advantages" but in reality it is only low gravity. also if you have a 2-3ton SUV, those 100-150 kg a bit lover are absolutely not noticeable... so only if you have a
+ktm640lc4BGD Yeah and your BMW height of perfection. Yes BMW's complete shit. Beautiful skin's all friable gearbox, glyuchanaya electrician and poor suspension. BMW shit.
+Dmitry Sti by your comment on the topic (boxer engine) i can see you are a smart guy.
+mystic1754 well i do not get it now... are you saying spark plugs on boxer or bmw are complicated to change? i think it is more complicated on boxer because on bmw i just have to take the top plastic cover and ignition coil (one screw) to access spark plugs...
+ktm640lc4BGD Whole story starts to flip when you think motorcycle. There's nothing more user friendly than a flat twin bike.
On a car however, there are some more advantage:
-Oscillating masses are completely nullified -> you wont need additional rotating masses to compensate
-Perfectly symmetrical ignition
-Biggest possible bores and displacement per cylinder
Yet, in the end I agree with you. Those advantages only really start carrying weight in the high end sports world. I love Boxer-Bikes for their torque, charisma and user friendliness, but wouldnt wanna own a car with it.
+ktm640lc4BGD well they are kinda annoying to work on. as the video said 6:58. they are kinda complex
As a new owner of an XV, and first ever Subaru in the family, I find the engine noise to be higher than the Mazda and Volvo that I've owned. Neither my '95 Volvo 960 12v-inline, nor my Protege5 and Tribute V6 had as much engine noise as this V4 Subaru. However, I like engine noise.
I took the XV on a very uphill & downhill curvy road going at least twice the speed limit for a one-lane road (60miles/hr vs 35 suggested). It handled with beauty!
I haven't heard that much
I've always loved Mitsubishi Lancer evos but I came across a 2002 Subaru Legacy Outback with a flat 6 3.0 safe to say I've had a change of heart and like I don't see myself selling this car and I'm happy to be a Subaru owner
The Mime scared me :,(
