Subaru FA20 Engine: A Step Forward for Subaru?

Here’s a look at the Subaru FA20D engine and how it works! The engine was also known as the Toyota 4U-GSE. These engines were used in the Toyota 86, Scion FRS and Subaru BRZ.
The FA20 engine was a modernized boxer series from Subaru that now used a timing chain instead of a belt and dual overhead camshaft with variable valve timing. Specifically, the FA20D had Toyota's D4S dual injection system, featuring both port and direct injection, which allows for a more controlled combustion for more power and less pollution.
Early FA20 engines, suffered from burning oil, which would eventually run the engine out of oil and cause catastrophic engine damage, like the one in this video. Valve springs failing were also another common issue.
Overall, the FA20 marks a progression forward for Subaru, with it now being currently its main engine in its line up of vehicles, with 2.0L and 2.4L variants, both naturally aspirated and turbocharged. It has replaced the ancient H6 boxer engines as well as the antiquated EJ series.

These engine tear downs are the ultimate ASMR videos for gear heads.

[@speedkar99]

Thanks, I enjoy them too

[@evgenysavelev837]

BRZ and FRS are suffering from this not because they are poorly maintained, but because they are often tracked, and sideways loads in corners usually send all of the oil to one half of the engine, which can lead to pick up tube being exposed to air. Mostly in long right handers or heavy braking. People solve this issue with baffles in oil pan and oil accumulators.

[@speedkar99]

Yep. That was a thing even with the older EJ motors.

[@Mattalaska]

I love my subarus, but boy their engines are not performance worthy

[@evgenysavelev837]

@@Mattalaska their engines have advantages. Short crankshaft, good balance. Maintenance is actually quite easy, if you know what you are doing. They have their weak spots, but they don't manifest, if you are maintaining them. The horror stories come from people who bought an abused car, or who abused the car themselves. These don't tolerate abuse as well as Honda or Toyota engines.

Ok new failure due to excessive silicone sealant blocking pick up lol

[@herniagaming]

That's not even engine specific I don't think, I'm pretty sure it's a problem for Subaru in general. I saw a guy on KZbin doing donuts in a WRX and the engine blew due to oil starvation just like these new rear powered sports cars they came out with recently. Sounds to me like the need to rethink their oil systems and pan designs at least on the sports models

[@jaymacpherson8167]

At 105k miles, my 1979 Subaru GL wagon’s water pump failed. That required lifting the engine as the cross member of the frame prevented removing the pump’s bolts. While the engine was lifted, I decided to disassemble to replace worn components. I was unable to split the case. So I took the block to a shop. A little backstory is useful before I go on: I regularly changed the oil and filter at or before 3000 miles. So the engine had 35 oil changes and filters (105/3 plus the first change at 1000 miles). The next day the shop owner called me up and asked how many miles the car had. I told him 105,000. He said “that can’t be.” I asked him “why?” He replied “because there is not enough wear on this engine!” I try to change my cars oil regularly.

[@speedkar99]

Good call

[@mikefoehr235]

Oil is so important...my Tundra is nearly at 50 000 kms. I am on my 5th oil.change. I do one every 10 000 kms even tho 16 000 kms is recommended

[@kevinwest1607]

I too regularly take my perfectly functioning engine out to be rebuilt, only to be told it doesn't need rebuilt!

[@K03sport]

​@@stewiegriffin6503 ... not necessarily OCD. an extra oil change per year isn't huge. and the relatively cheap cost of the oil change is pennies compared to major engine parts failures. Going early on a oci isn't terrible as you keep newer/fresher oil in the engine. Going too early is wasting time and money. OCI in the owners manual are only recommendations and cannot account for every situation/environment. I change my oil at/close to 5k miles despite Subaru saying 6k miles. I still average an oil change every 5 months vs 6. Plus, going every 5k gives me some fudge room to account for time available.

[@michaelbezoski3096]

Gosh, looks like the owner followed the dealer recommended 7,000 + miles interval between oil changes. Possible thought they could go that long before checking oil level too. As others have said, great channel Bro. We appreciate the work it takes for our education and entertainment.

@@AlternateRye So I just looked it up and 7500 miles is 12,000 kilometres. What's insane about that?

That’s what I always do on any of my cars. The added RTV sealant costs SFA and might save you from having to pull it all apart again in a few years time when the rubber gasket lets go.

[@jsun3117]

@@speedkar99 the shop I worked on and off always put a thin film of rtv on the valve cover gasket housing areas and put the gasket in-between and never had a problem. A mared or compromised surface can't be helped by a premium expensive gasket as the micro gaps would leak way sooner but with the help of rtv those cracks/gaps get filled. Another thing it was the 24 hr cure cheaper RTV but the customer was able to drive away within an hour with no issues with the help of a gasket core + RTV.

What happens if you overfill engine oil by a quart? Where does it go? If you don't start the car for too long, do the parts get too "dry" or damaged in first few seconds of starting before oils gets there? Thanks again, highly informative videos, love them.

[@KortezRisma]

If you overfill an engine itll go into the pan like normal, sometimes it isnt a big deal but of the oil gets to close to the crankshaft it can cause windage or frothing. If a car has sat for a while parts will generally still have a thin layer of oil on them that will provide enough protection for the couple seconds before oil pressure is reached

[@108padma]

Don't overfill! The crank will dip into the oil with each revolution, causing frothing that will reduce the oil's ability to protect the engine from wear.

I'm a huge fan of the original Volkswagen Beetle engine: it is utter simplicity. When I see a Subaru engine, I can't help but compare them. The Subaru, with the complexity of water-cooling, overhead cams, and all that, is hopelessly overbuilt.

[@sagesends]

brother by that logic every modern engine is overbuilt. I see Toyota engines with overhead cams and water cooling regularly going 400k miles without a major rebuild. I don't think an air cooled volkswagen engine can say the same.

[@martin-vv9lf]

Water cooling massively helps longevity though. I've heard it said that 6 cylinders tend to blow the head gasket because the head is so long that it expands, and because of the temperature difference between the front and rear of the engine. The boxer head being two cylinders shouldn't suffer as much. I think the boxer design is better suited to a pushrod to keep the weight and size down.

Didn't they have oil use issues in this period due to low tension rings ? Early FA 20's

[@Antykain]

My 2015 WRX recently had a visit from Uncle Rodney.. It's in the shop currently getting a replacement long block installed. Sucks man. This is the first issue I've ever had with the VA WRX since owning it, outside of regular maintenance. I was that guy saying, "Rod knock won't happen to me. I take care of my shit and maintenance is on point, sucka!" Well, yeah.. it happened. To add to that, extended warranty expired.. so, repairs are out of pocket. ☠☠ Good times!! Anywho, just lookin forward to getting her back on the road again! Already miss driving it..

[@rexisretro]

My fault if this is a personal question but out of curiosity what do you do for a living?

[@vapor4den]

2:59 Rod knock at 114'000klm !? 😮 How to prevent this ? What oil will you choose for the FA20 ? I have fear now that I know it's happening at sunch low KLM... Is it really low on oil and with hard cornering/High revving the engine starve oil or something like that ?

[@speedkar99]

Yes. Alot of 2012/3 models suffered from these failures.

[@neometalx9]

is this the same engine that comes in the crosstrek?

[@DanteTheAbyssalBeing]

Are they generally reliable engines? I really want a GT86 but after years of Honda ownership I'm not used to having to fix anything on my car haha.

[@speedkar99]

Get 2015+

[@fredautos]

Just surprised that, The FA20 doesn't have as much complicated design crap.. Just a simple v4 engine . Quiet interesting to know-*

[@PhyuckYew]

This isn't a "v4" This is a boxer engine. It's a flat four engine.

[@fredautos]

@@PhyuckYew oh thanks man

[@speedkar99]

Honestly it's not that complex.

[@andererkanal8089]

Honest question for the community. My GT86 broke down last week, most likely because the camshaft hat a defect. Im not a mechanic but I always tell me that I have good technical understanding. Because the motor is already fucked and I dont have the money to pay a mechanic to repair it, I thought about try to do it my self. Firstly, what do you think about this Idea. Secondly, is there anything like a blueprint or something like that where I can see how the motor is built? Thanks alot :D

[@10forthebigguy753]

Who thought 9 feet of timing chain was a good idea?

[@speedkar99]

The chain making company

[@zacharyparis]

Curious what changes they made for the FA24?

[@speedkar99]

Me too. I'm sure they've bored out the block

[@Skillzpatchi]

Rather that a slightly bigger engine I believe it's pretty much the same except for the fact that the literally put way to much rtv on the oil pan which some of the rtv is breaking off and going into the oil pick up tube and starving the engine of oil.... so anyone buy the new 86/brz/frs make sure you check that oil pan

[@zacharyparis]

All the research I’ve looked at shows the RTV hasn’t caused any oil starvation. It does, however, get low oil pressure on high G right hand turns when on track.

[@saad8029]

@@Skillzpatchi RTV in the pickup mainly comes from the timing cover, not the oil pan. As long as excess rtv is not causing issues, which it really hasn't, no dealer or even Subaru/Toyota will clean the pickup for free. Its messy and even I don't like the excess rtv but that's how it is. Oil starvation on track causing engine failures on the other hand is a separate issue that has been mistakenly linked to excess rtv.

[@Skillzpatchi]

@@saad8029 well I seen couple video talking about the Excessive rtv use on the oil pan from factory which the main reason why the boxer engine like to die, I believe speed academy and I forget the other was talking about it

[@maikelnait4495]

Really clean. So the oil was changed frequently enough and still failed. Bummer.

[@speedkar99]

Yes...too bad it wasn't checked

[@MegaNardman]

​@@speedkar99I don't think it's a fair assumption that the oil was run low here. These engines are notorious for starving the pickup under certain conditions, and pooling oil in the heads. You yourself pointed out that there wasn't any evidence of oil consumption, and remarked how clean the heads looked.

[@sarunasbriedis]

Post the pic of the table. I want to get one from scrapyard and do it myself. Just need to talk by better 3/4 into this

[@speedkar99]

Sure. If I get the chance. It's now winter here

[@patrickkennedy2533]

not only is that my engine , that's my toothbrush

[@speedkar99]

Hi!

[@jophillips2868]

Are all of the new 2.0 and 2.5 duel cams

[@speedkar99]

Yea

[@brettito]

I need to check my oil.

[@PJBonoVox]

Stick a low pass filter on the audio or something dude. The high pitched noises are killing me 🫠

[@speedkar99]

Sorry. I need an external microphone. It would complicate things in editing vastly though.

[@PJBonoVox]

Yeah, I didn't mean to bust your balls. You can only work with what you have.

[@tt6368]

Ive been trying to buy the toothbrush for a while now but none of the auto parts store i visited sells it.
