I think the only reason the EZ isnt in S-tier is because it was really only in less sporty subarus. Absolutely great engine, wish it had more applications.
That’s completely fair, I can’t imagine if they offered a higher BRZ trim with it how fast they’d sell. Similar to how the Supra can be bought with a 4 or 6 cylinder
Some countries (Australia, NZ, UK, a couple others) did get a sporty version of the Legacy with the EZ30 mated to an STI-derived 6 speed manual and it's an excellent car to drive. Definitely would have been great in something like a BRZ too. There's a lot of aftermarket development for it too and a well-maintained engine can push 400whp with stock internals once you add a turbo
The boosted and unboosted FA24s have completely different internals and shouldn’t be considered truly the same engine, even if they’re part of the same engine family.
@ cannot speak to that but I can say it’s similar to the boosted K Series in the Civic Type R and how that differs substantially from the legendary naturally aspirated K Series engines that everyone knows and loves.
I’m not sure if this is true. Can’t find anything that shows the 24F and D don’t share the same internals or at least aren’t significantly different, you have documents saying otherwise? I’d be interested to know if the FA24Fs internals are stronger than the D. The FA24D is higher compression and dual injected obviously NA too. That’s the only big differences as far as I know. The oil pan is also a different shape too, I *think*
@@MrThewetsheepas far I know the turbo variant has internals for lower compression. But not much else that really sets it apart. Turbo second gen 86/BRZ are putting out comparable numbers with just bolt on kits
@@MrThewetsheep there’s an interview in Japanese with one of the Subaru engine chiefs. He confirms that the FA engine in the Ascent and WRX is very different from the FA in the BRZ.
2:00 I feel it's worth mentioning what makes a boxer isn't just being a flat 4, it's the firing order. Watching it in motion resembles a 1-2 punch on both sides
I thing the eg 33 should have been at least a tier I have a svx with 250k miles on it and it was sitting outside on a farm without being run for 10 years and all we had to do was replace on wire and it ran perfectly it’s a really good engine
I have an EA81 in my 82 GL and its awesome. Great mileage, great sound. Swapped EA82 pistons into the EA81, since its the same bore and pin size, and was able to raise my compression from about 8.7 to 9.1
God i love my dad's EZ36 in our 2019 Outback Touring, bought another one for almost the engine alone. thing has loads of power and a sound so exquisite and unique.. that no other car in the world could make it, except a porche with a modded exhaust lol. The Legacy and Outback are also the only cars ever to be produced with AWD, a Boxer 6 cylinder, and a CVT transmission. S tier engine in my heart forever and always. ❤
Great video. I know you only did automotive engines, but you should make another video in the future to include power sports engines. Subaru made/makes lots of the 2 and 3 cylinder engines for Polaris/Indian. I’m not sure if they still make engines for Polaris, but I know the 90s-00s Polaris snowmobiles used Subaru engines.
Absolutely love the EZ’s. I ended up EZ30R swapping my forester, was a good bit of work in wiring, but so much fun when bolted to a MT whether it be 5spd or 6spd. Those motors are even more fun when you boost them!!
Critiques: EZ belongs in S tier (at least above EJ. We are judging the engines, not the cars they come in. EJs should have been split up, they are not a monolith. Some were bulletproof, others were essentially trash. (For example: EJ207 or EJ22 vs EJ251 and early 253.
And not all ejs with the same name designation are the same for example the first version of the 255 is literally just a first gen 257 (04 sti) with different manifold turbo and other slight differences ver2 255 is the higher compression one found in the WRX and there's even another version found in the legacy gt gen 5 with a front mounted turbo
I own a 2010 Subaru Impreza 2.5l and at 145k the head gaskets failed. Thankfully my engine didn't blow in time for me to replace them with good quality gaskets. Definitely worth the investment. I don't have oil leaks but I understand that it eats up oil requiring you to check your oil level weekly.
The problem years for the n/a ej 2.5 were in the late 90s. They fixed the problem of the faulty head gasket but the issue persisted in some models until 2009.
If the EJ is in S tier then the EG should be as well. Little known fact is that the EG33 is just the EJ22 with 2 extra cylinders. There’s guys on here that boost them and use parts straight from the EJ catalogue haha
in my experience of 14 cars and working on them all the time the EZ30 is by far the most reliable Subaru engine, they take a beating pretty good too. Surprisingly the 20x in specific has also been stupidly reliable. I used for skids for like 2 seasons so far
A bit early to give it a rating. Pretty solid so far and 29 mpg in a Forester is great. The '25 plus models will probably deserve A tier after they ditched the TCV and gave it a bump in midrange power.
EA82T and ER27 have to be the most frankenstein engines of Subaru. Both are developments of carbureted, siamese inlet & exhaust EA82, but with oddball modifications. Probably a resource/time issue, since they had completely new EJ engine and Legacy in development in the late 80's, and had to keep EA82 series somehow alive and competent for 1985 - 1990
The EJ22T is in my opinion the best engine we got in the US as it was the only closed deck engine we ever got. The regular EJ22 did not have the closed deck. Subaru has caused themselves numerous head gasket issues by not having closed deck engines. I've had an EA81, EJ22T, and an EZ30. The latter 2 with 300,00 and 250,000 respectively.
ez30 is such an amazing engine. i loved it in my 08 3.0R. I regret selling that car, the FB20 in my current imprezza just doesnt hit the same. dont get me wrong i still like my impreza but it just feels gutless and disconnected compared to my old 3.0R. but atleast my fuel economy has been WAY better. the ez30 is exremely fuel hungery if your not super careful with your foot + premium fuel
The Fa20 should be separated from the fa24, the aftermarket potential of the fa24 even in it’s stock form is insane. Brz’s are hitting 450whp for over 60k and someone dyno’d at 600+ AWHP in a vb wrx. Seems like the next big tuner motor to me.
As to the EZ 3.0 engine these two years (2006 and 2007 had aluminum alloy blocks, forged reciprocating mass (pistons, con rods and crankshaft) an incredibly strong engine….
I'd argue that the EJ253 belongs with the 251 and 252 since I see a lot of the same failure points on the 253 and have seen 2 throw rods through the block in 3rd gen Outbacks personally, but at the same time the 251,252, and 253 can have the head gasket issue fixed by simply replacing the standard single layer graphite gasket with a MLS gasket for a WRX and with that simple switchover these 3 different variants that couldn't go past 80,000 miles without needing a head gasket replacement can go upwards of 300,000 miles with little to no issues, however since this is rating them how they came from the factory I feel like everything is in the proper spot except for the EJ253 as I mentioned before
The ej253 is kind of a weird duck in that because it was used so long, the later years fixed it with an MLS gasket. My 2011 impreza hatch came from factory and is currently sitting at 232,000 miles with zero issues. It may or may not have come up in the research for the video just because it varies based on who you ask. Or rather, the vintage of their 253
Yeah. The early 253s were literally just 251s running a MAF instead of a MAP for air sensing purposes. Eventually they started going techy with the 253 adding E-throttles, AVLS, TG valves, etc along with a completely different piston shape. The real problem child that he should have mentioned out of the 2.5s was the original '96/7-'99 25D. Those made the head gasket issue known, but they also had a variety of other issues. Being dual cam unlike nearly every other NA EJ, if the belt snapped, not only would the piston clamp the valves, but the valves would hit each other too. They also made pretty weak power at about 150hp compared to 170 in later 2.5s and required premium gas despite being a lower compression ratio that later models. For the last year ('99) they used an amalgamation of parts from the original phase 1 25D and phase 2 251. Top end was still 25D, but bottom was 251. They also ran a phase 2 ecu, (though the computers themselves weren't that different).
I have a 08 legacy 2.5i with the 253 with 230k that thing is daily beaten and has been my winter car for a long time with minimal maintenance. It is ironically my most reliable car I own and has so far taken everything I've thrown at it with no problems, engine sounds good, purrs on idle and screams till redline with no complaints
@@jinezawa7089I've got a 2012 legacy with an ej253 and it came with the graphite head gasket but we upgraded to the multilayer steel gaskets. Now my only concern is the sketchy CVT that's in that car rn. At 194k
@@bcyr-CO I personally own a '97 Legacy GT that has a 25D in it and it's currently sitting just shy of 228,000 miles with no major issues on the engine itself, the heater core just needs flushed and there are a few leaks but that's to be expected of a car with that kind of mileage, also the requirement of premium fuel was a first year exclusive deal since Subaru revised the engine for '97 and it made the same power as a 251 but could be run on 87 with no issue, and I've done just that for as long as I've owned the car and it doesn't feel down on power nor does it feel like it's going to blow up soon, now I do believe one of the previous owners of my Legacy did put MLS gaskets from a WRX in it because the gaskets do look pretty thick to be a single layer gasket.
The EN is a Kei car engine and was artificially limited to stay under the government limits for power due to that. It's not hard to get close to double the horses with some small mods...
Great video and very interesting! I just wanted to clarify one thing, the UEL headers contribute to the legendary boxer rumble but do not entirely produce it on their own. The legendary boxer rumble comes from the boxer engine design and likely firing order, etc. You can find countless videos of STis on YT with ELH setups and they still have quite a bit of rumble. It is less prominent but you can still clearly hear it. There is more to an engine's sound than its exhaust setup. That is why no other engines sound like EJs, VQs, LS's, Coyotes, JZs, RBs, Rotaries, Diesels, etc. An engine's mechanical design, firing order and other factors above my knowledge level produce a sound unique to each engine.
Just got a '12 3.6r Outback with 5 speed automatic, to go with the' 18 Forester manual 6 speed and '20 Outback CVT in the driveway. Gotta say, really liking the pull of the S M O O T H flat six, the direct connection of the manual and.....ummm.....Im sure the wife likes her 2020 cvt...😅...
The EZ30D mk2 in the Tribeca 06-07 and some Outbacks, had ‘Subaru Active Valve Lyft Sytem’ which was similar to Porsche VarioCam. You take the some of the internals from a Porsche boxer engine in their Boxster and incorporate it because of that.
Да, у двигателей серии турбо дизель ломало коленчатый вал, но после 11 года субару усилили этот узел, так, мой двигатель прошёл уже 300к и я заменил у него двух массовый маховик на одно-массовый, это очень тяговитый мотор, с помощью "чип-тюнинга" вырезав всю экологию и замена выпускной системы удалось выжать 200 сил и 450 момента на 1350 кг (subaru xv), так что, кому интересен сам концепт турбо-дизеля от субару, я могу порекомендовать брать двигатели/машины после 11 года.
I have a 04 Legacy with the EZ30 I love this car so much it has 306.500 kilometers or in american Miles 190.450 Miles also just recently I changed the Oil the Filter the airfilter for the interior also it my First car too ❤
I had an 04 outback sedan with the ez30d and its supposed to be reliable. It blew its head gaskets at 160k miles. Subarus are cool when they work, they aren't when they don't. I did all preventative maintenance too. I guess for Subarus the preventative maintenance is just replacing the motor lol
The RTV in the oil pan is no longer generally considered the cause of the issues with the FA24 although it’s prolly not a bad idea to clean it out. Oil pressure drops have been very very blow out of proportion. In long sweeping high G turns on track, autox etc you can drop oil pressure. This is probably due to too low oil capacity. None of the GR cup cars have had issues that weren’t caused by negligence or a team making a calculated risk (using less and thinner oil to gain power) they also use a thicker oil and generally overfill by a liter or so which for most people have fixed the issues. Tests with larger oil pans have been very promising.
JDM EG33 is about 250hp, and on 87. Ive drived it on 91 and 87, zero difference in power or fuel economy. I think its a solid A tier, and thats considering parts are very hard to find.
@ no sir 🤣 I blew my EA888 gen 1 up by applying to much boost lol.. it’s just a common thing in your community.. by the way I’m a mustang owner too so rip away
Fa24 isn’t in the same class as the fa20. You Can get much much more power for much less. And the rtv issue was only for a year. Never heard anyone question the reliability of the fa24
The real question is what is the ez36 capable of. Think all billet construction gorged pistons titanium rods forged crank titanium valve. And two big ass turbos.
The only thing i will say is the EJ family of engine are generally ok engines. There are some that a complete boat anchors, most average and a very small hand full that completely destroy the rest of them. The stand out engines are the EJ20G, EJ22T, EJ22G. Those 3 EJ`s stand alone an none compare stock for stock NONE! You can take an EJ22T and double the factory output and the engine will be fine this is possible because the engine block is close deck and better internals. The EG and EZ legit are the only other subaru engines of any value mainly because they are strong AF also when built and boosted can make gobs of power and take it no problem. Great engines that are well designed.
Ej257 STI USDM should be on a or b tier Ej207 JDM only on s tier cause it has no gasket problem or a lot of problem like 257 ej207 jdm is more durable and much more potential but you pay extra more also
I've driven an early 2000's Porsche boxter with a flat 6, and a subaru outback with the EZ flat 6. I know it may sound crazy, but I'd take the EZ all day over the Porsche
@@Sheriff_McPantsit’s not though. They’ve been testing them in accents since 2018. The FA24 and EJ257 are Subaru’s only S tier motors we’re being real. Stopped watching after he put the FA24 in A tier like it’s on a similar level of the FA20.
Glossing over the FA24DIT like it's the same as the 20 is weird to me. Pretty much proves that the guy who made this isn't working with a lot of information, or is cooking with bias.
There was much cooler engine) Subaru 1235 - Flat 12 3.5L engine, which produces 425-560 hp and 220-245 lb.ft of torque. F1 engine that weights only 159 kg!
The clover four doesnt deserve that low a tier. It only makes 64hp because of laws that limit kei cars max power output at 64hp. It's probably one of the most reliable Subaru engines out there
As an fb20 owner SUCKIT. Lol i have a snorkel and shit and have had 0 issues. Plus mind u i have a 2.5” lift, a/t’s, a steel bumper, buncha lighting. Anyone who says oh hurr durr head gasket gets a big laugh from me.
@@scottmaness4449 Maybe, I would like to see a list on the brand. I own a 206 GTI 135 and the engine I believe is supposed to be pretty reliable. So far for me has been
@@scottmaness4449 French cars in general don't have the best reputation, Peugeots in particular are not great in that department, but there are some gems I think, and also most of their faults are electronic failures from what I hear, so far so good on mine in that regard also. Not sure about other engines but the one from mine is supposed to handle around 300k km which is not bad
I think the FA deserves C tier due to many reports and documented research on its Achilles heel: long right turns. It starves for oil and pressures drop over 50 psi sometimes due to it.
I can personally go and buy at least one or two of the EE Diesel's very cheap right now with a blown engine. The fact that the diesel's can be bought as parts cars' every week in our local small car market with blown engines(Norway) should tell it all. One of the worst engines Subaru ever made.
That only how Idiot American think cause best they can get is ej257 with a lot of problem like head gasket problem etc JDM don’t have any kind of problem like also you know nothing about Subaru maybe you are poor or not educated yourself
@ us Americans like reliable hp I’ve owned 2 Subarus and worked on many. they are all trash. 2 timing belts and 4 camshafts to max out at 400hp without doing a full build is a waste and even fully built they blow after a month at 600hp you fan boiz will never accept the truth 😂
@@M-PASTAI’ve had plenty of Subarus come into the shop for simple things like oil changes, inspections, etc. I’ve got a dozen or so regular customers with 200k+ mile Subaru’s with the stock engine.

There is more to an engine's sound than its exhaust setup. That is why no other engines sound like EJs, VQs, LS's, Coyotes, JZs, RBs, Rotaries, Diesels, etc. An engine's mechanical design, firing order and other factors above my knowledge level produce a sound unique to each engine.
Really neat stuff, thanks for sharing this! Engine acoustics is such a fascinating science
Name a destination in the contiguous 48 states and my EZ30D has probably been there. Has such smooth power and very nice to work on.
That’s impressive, certainly a stout engine
I have an idea for another video, maybe you could rank all of the Jeep engines ever made!
Just got a '12 3.6r Outback with 5 speed automatic, to go with the' 18 Forester manual 6 speed and '20 Outback CVT in the driveway. Gotta say, really liking the pull of the S M O O T H flat six, the direct connection of the manual and.....ummm.....Im sure the wife likes her 2020 cvt...😅...
Ez sure are smooth, thanks for watching!
The EZ30D mk2 in the Tribeca 06-07 and some Outbacks, had ‘Subaru Active Valve Lyft Sytem’ which was similar to Porsche VarioCam. You take the some of the internals from a Porsche boxer engine in their Boxster and incorporate it because of that.
hey dude i love these videos and i was hoping you could do an american 4 cylinder tier list soon, keep up the good work
I’ll get to it soon, I appreciate that!
Love doing burnouts in my ea82 in-front of newer subarus😂
Да, у двигателей серии турбо дизель ломало коленчатый вал, но после 11 года субару усилили этот узел, так, мой двигатель прошёл уже 300к и я заменил у него двух массовый маховик на одно-массовый, это очень тяговитый мотор, с помощью "чип-тюнинга" вырезав всю экологию и замена выпускной системы удалось выжать 200 сил и 450 момента на 1350 кг (subaru xv), так что, кому интересен сам концепт турбо-дизеля от субару, я могу порекомендовать брать двигатели/машины после 11 года.
Love this series of videos👍🏻
LETS GOOOOOO. IVE BEEN YEARNING FOR THIS VIDEO FOR MONTHS.
The fb20 in the impreza is very fun to wring out. I take good care of mine and hope itll last me a long time.
Turbo FA24 is leagues above the FA20
I have a 04 Legacy with the EZ30 I love this car so much it has 306.500 kilometers or in american Miles 190.450 Miles also just recently I changed the Oil the Filter the airfilter for the interior also it my First car too ❤
That’s a lot of miles and a testament to the EZ quality, thanks for watching!
@ no Problem I love this car ❤️
I had an 04 outback sedan with the ez30d and its supposed to be reliable. It blew its head gaskets at 160k miles. Subarus are cool when they work, they aren't when they don't. I did all preventative maintenance too. I guess for Subarus the preventative maintenance is just replacing the motor lol
V7+ EJ207s 🔛🔝
There is also 2.6L EJ engine that was never offered for street car, and STi TC380 with you know 380HP high output special edition.
Please make a nissan 4-cylinder list
The EJ22 in the Legacy GT is probably the best short block E series engine.
What year lgt had the ek20?
@ sorry james, I meant the EJ22. The first generation Legacy GT had them.
The RTV in the oil pan is no longer generally considered the cause of the issues with the FA24 although it’s prolly not a bad idea to clean it out. Oil pressure drops have been very very blow out of proportion. In long sweeping high G turns on track, autox etc you can drop oil pressure. This is probably due to too low oil capacity.
None of the GR cup cars have had issues that weren’t caused by negligence or a team making a calculated risk (using less and thinner oil to gain power) they also use a thicker oil and generally overfill by a liter or so which for most people have fixed the issues. Tests with larger oil pans have been very promising.
Do Nissan Please we need the heart of big Altima energy on that list 😂
With how I see those driven I can’t deny they’re reliable haha
I believe that the EJ in the S208 belongs in the S tier
JDM EG33 is about 250hp, and on 87. Ive drived it on 91 and 87, zero difference in power or fuel economy. I think its a solid A tier, and thats considering parts are very hard to find.
Can we get a rotary engine tier list?
Love the idea, thank you and I’ll make it happen!
This video would easily hit 1 million views if the thumbnail was all the engines in the D row 🤣😂
Gotta tap into the massive Subaru hater community😂
@ no sir 🤣 I blew my EA888 gen 1 up by applying to much boost lol.. it’s just a common thing in your community.. by the way I’m a mustang owner too so rip away
No stick shift EZ is the real problem here. I would put an EJ255 over a naturally aspirated EJ22.
They made plenty, 6 speed manual EZ30 Legacy/Liberty, just not in the USA...
@ gotcha. Thanks, it’s tough to not have any twin turbos here either.
Hi small correction, the EE20 came on 2008 and 2009 impreza too
EJ22T FTW. Replace lame heads with DOHC heads and crank up the boost.
I have a 1988 Subaru RX with thw best iteration of the EA82T. It’s been replaced or refreshed 7 times. I’m EJ swapping it. Lol
Fa24 isn’t in the same class as the fa20. You Can get much much more power for much less. And the rtv issue was only for a year. Never heard anyone question the reliability of the fa24
i miss my 96 outback wagon.
The real question is what is the ez36 capable of. Think all billet construction gorged pistons titanium rods forged crank titanium valve. And two big ass turbos.
Ez36 is S tier. 150k driven hard miles with 0 reliability issues. Cant do that in an EJ
The only thing i will say is the EJ family of engine are generally ok engines. There are some that a complete boat anchors, most average and a very small hand full that completely destroy the rest of them. The stand out engines are the EJ20G, EJ22T, EJ22G. Those 3 EJ`s stand alone an none compare stock for stock NONE! You can take an EJ22T and double the factory output and the engine will be fine this is possible because the engine block is close deck and better internals. The EG and EZ legit are the only other subaru engines of any value mainly because they are strong AF also when built and boosted can make gobs of power and take it no problem. Great engines that are well designed.
Hey man, can you do I4 nissan engines, I got a b16 sentra spec v, it would be cool to see what you have to say about it.
Ej257 STI USDM should be on a or b tier
Ej207 JDM only on s tier cause it has no gasket problem or a lot of problem like 257 ej207 jdm is more durable and much more potential but you pay extra more also
I have a 2016 Outback 6 cylinder, is that the EZ? Love the engine and car overall.
I believe so, thanks for watching!
They muzzled the EZ's with awful headers in order to not outshine the WRX turbo engines, total conspiracy
So are new outbacks with turbos using the CB?
It can be found in the “Legacy Outback” and may be country specific. The main engines used though are the FB25D and FA24F
What about that K20 engine in the Hondaru? 😂
My personal take is it’s better than the Subaru engines, I did hit the K20 in my Honda list
@running2redline wow that's interesting. Can you tell me more about why it's better than thr Subaru Engines?
I’d place the FA24F over any EJ
EZ needs to be S tier
Fa24 pros over the 20 should put it in S. Best engine subarus ever made for power and it is stronger than the 20
Ej207 is the goat
So is the ej207 one of the most reliable engines?
As far as Subaru engines are concerned that is one of the most solid based on my opinion after digging through forums and warranty claim data
Mitsubishi engine tier list next
The fa24 is easily better than the ej. the fa20 not so much. A nice video keep it up!
Much appreciated, FA24 is certainly a strong engine!
The newer technology should prevail. The FA20 failed to surpass the EJ IMO but the FA24 seems to do the job
emanual sounds like a good site to get info, but they dont have the gen 2 brz :(
That’s surprising, I’ll look into it they have the GR86 maybe
EZ should be S tier. Only S tier EJ is the V7 EJ207. I'll die on this hill.
I've driven an early 2000's Porsche boxter with a flat 6, and a subaru outback with the EZ flat 6. I know it may sound crazy, but I'd take the EZ all day over the Porsche
@@electronitrasI heard Porsche and Subaru worked on the EZ block architecture together.
@@suzumr2754not surpising considering they supposedly worked together to develop the ty85 transmission in the sti
I agree ej is king.
german i4 next?
Where can I get information on swapping a 2.2 EJ into a Brat? Specifically, wiring up the ECU.
I personally would have no idea. If anyone reading this does, please enlighten us. Sounds like a fun project!
Eg33 is the king of subaru engines other than the ej22 or ej207. They are much more capable than the ez, especially when boosted!
EJ207 gang WYA?
EJ205 on top
I love my 1984 BRAT (EA81) & my 2006 Outback XT (EJ257) ♥️ I hope my kids enjoy the rumble and burning oil long after my passing 🥹
FA20D/4U-GSE deserves S-Tier so much!
FA24 should be in S group
Did I miss the part about EJ257 or was it not mentioned
It’s included with the EJ in S tier
E255 gang stand strong 💪
Fa20dit is A tier fa24dit is S tier
I'd say that the FA24dit is to new to make this argument. I'm sure over the years issues will become more apparent.
@@Sheriff_McPantsit’s not though. They’ve been testing them in accents since 2018. The FA24 and EJ257 are Subaru’s only S tier motors we’re being real. Stopped watching after he put the FA24 in A tier like it’s on a similar level of the FA20.
I agree, FA24 is solid and can take a beating.
Glossing over the FA24DIT like it's the same as the 20 is weird to me. Pretty much proves that the guy who made this isn't working with a lot of information, or is cooking with bias.
@@Sheriff_McPants it has been out for over 4 years now.
There was much cooler engine) Subaru 1235 - Flat 12 3.5L engine, which produces 425-560 hp and 220-245 lb.ft of torque. F1 engine that weights only 159 kg!
The fa24 is far superior to the fa20dit in stock form both have poor silicone assembly procedures
The clover four doesnt deserve that low a tier. It only makes 64hp because of laws that limit kei cars max power output at 64hp. It's probably one of the most reliable Subaru engines out there
As an fb20 owner SUCKIT. Lol i have a snorkel and shit and have had 0 issues. Plus mind u i have a 2.5” lift, a/t’s, a steel bumper, buncha lighting. Anyone who says oh hurr durr head gasket gets a big laugh from me.
Definitely underrated engines
Vb??
thats a body code not an engine code?
Peugeot tier list?
Z. Peugeot diesels were some of the worst l've worked on in equipment.
@@scottmaness4449 Maybe, I would like to see a list on the brand. I own a 206 GTI 135 and the engine I believe is supposed to be pretty reliable. So far for me has been
@@tyuy100 gassers may be a different story. I have no experience with them, though I have heard things.
@@scottmaness4449 French cars in general don't have the best reputation, Peugeots in particular are not great in that department, but there are some gems I think, and also most of their faults are electronic failures from what I hear, so far so good on mine in that regard also. Not sure about other engines but the one from mine is supposed to handle around 300k km which is not bad
All Subaru boxer engines belong in d tier
Educated yourself
Rip subaru
I think the FA deserves C tier due to many reports and documented research on its Achilles heel: long right turns. It starves for oil and pressures drop over 50 psi sometimes due to it.
I did hear of this when I owned a BRZ, are there aftermarket solutions?
@running2redline from what I can tell, there's a few options that don't fully fix it, and they void warranty if installed.
love my slow ass 2.2
I can personally go and buy at least one or two of the EE Diesel's very cheap right now with a blown engine. The fact that the diesel's can be bought as parts cars' every week in our local small car market with blown engines(Norway) should tell it all. One of the worst engines Subaru ever made.
Sounds like it’s in the right spot then, thanks for watching!
Can I literally just trade you my fa24 for a k swap
Now let’s see the best Subaru engine vs Hondas worst engine. 💀
Ej207 vs K20a?
no Subaru engine is an S tier, lets be honest
That only how Idiot American think cause best they can get is ej257 with a lot of problem like head gasket problem etc JDM don’t have any kind of problem like also you know nothing about Subaru maybe you are poor or not educated yourself
@ us Americans like reliable hp I’ve owned 2 Subarus and worked on many. they are all trash. 2 timing belts and 4 camshafts to max out at 400hp without doing a full build is a waste and even fully built they blow after a month at 600hp you fan boiz will never accept the truth 😂
@@M-PASTAI’ve had plenty of Subarus come into the shop for simple things like oil changes, inspections, etc. I’ve got a dozen or so regular customers with 200k+ mile Subaru’s with the stock engine. Only blown up ones I’ve seen are ones with neglectful owners, or racer kids with Chinese parts and rubbish Cobb accessport “tunes”. There are lots of high mileage, properly built and tuned Subaru’s on the road with 400+whp.
It’s all relative, but I’ve personally been lucky with Subaru engines up to this point
