The failed one was the worst one.
My favorite thing about these engines is that they made a huge amount of power for their size and revved like crazy, and yet they use regular oil, they’re pretty reliable and they’re incredibly simple. It shows that with proper engineering, you can make a high performance engine without making it super delicate like the BMW S-engines and all of the Italian exotics.
Yes, but it also shows how holding on to a concept for too long will see diminishing returns. When Honda introduced the V-Tec concept, everyone was blown away. And although Honda kept developing it somewhat, the competition didn't sit still and the VVT-L (Variable Valve Timing and Lift) concept simply outperforms V-tec. I think it's fair to say that what put Honda ahead of the competition with their innovative solution, also has held them back to the point of falling way behind that same competition.

the S60R/V70R engine is awesome. It as an issue tho. I might be mistaken but the block is still the 250hp t5 one, but due to the extra HP and torque, the stress might cause the blocks to crack. Both cars (S60R and V70R) benefit tremendously having a blockguard put in the motor and a reinforced transmission link from the gearbox to the rear transmission shaft, two of the weakest spots in those guys.
These F20 series engines are very well engineered, reliable and pretty tough. So to see one blown up like this speaks volumes to how hard this engine was abused. They’re forgiving to an extent, this is what happens when you go over that limit.
maybe a track day though no baffles in the oil pan and oil starvation could have caused this also all the stuff in the oil pump meant it was still running after the damage...
Mechanical over spin while going from 3rd gear position to 2nd instead of 4th. If you were to extract the DTC information from the E.C.U., you might possibly find 11,000 RPM failure!
I'm a fairly recent subscriber, but love viewing the disassembly videos. Such a relief to watch someone working who really enjoys what they do combined with the gentle humour in the commentary, the first time I heard "disconnecting rod" nearly choked on my coffee. Also a relief to watch a channel that's not trying to sell us everything from VPN's to financial services. Yes of course you've a business to run and promote but it's done in a no nonsense, not shoved down your throat fashion. Love it 🎉🎉👍
I'm on 122k, I'd be interested if you've had to do any major maintenance on yours in your time- needed to change bearings or anything? I'm planning on doing rod bearings and valve retainers this year, as a bit of preventative maintenance
Generally the bottom end holds together when the F20c is over revved, however the valve retainers are known to crack and cause them to drop valves, which does cause total failure if repeatedly over revved
I used to drive an AP2 S2K. Mine had the F22C1. Such a fun and responsive car. I hate to see them abused like this since they're so rare and beautiful. Thanks for posting this one!
I bought a 2007 S2000 that the engine failed shortly after I bought it. The first thing I found was crank end play of .125 and upon tear down I found thrust washers in the pan. Other damage was scored cylinders, three spun bearings, damaged crank, and damaged block. I suspect the previous owner neglected to check the oil level and ran it low. I was lucky to find a used engine for $4500 that came out of a 2007. I really love my S2000, it a thing of beauty to drive.
F20 stock ran to 9k. Only the less interesting, but higher torque F22 revved to around 8k. Most likely this was a mechanical over-rev. Based on the aftermarket VTEC solenoid and the K&N filter, that guy had no idea what he was doing. So no surprise that he money shifted it.
Wow that’s a sad sight. Often touted as one of the best 4 cyl engines … it met a sad demise. Thanks for the tour. Owned a B18C engine and they are a great motor from a great era.
Eric, with the S2000 engine it was all about NOT exceeding the piston speed, you really didn't want this baby to rev any higher than it was designed too. Things start to go badly if the rev limiter doesn't do it's job correctly. Thanks for showing us this beautiful engine in detail, and thanks for another nice video!
@@brysonshires9742 You can do that with a racing K24, by balancing all of the components and also tearing it down frequently to check your bearings, gaps and tolerances. I advise against doing that to a Built-for-the-Street K24, unless someone else is paying for your engines.
@@ericecklund676 yeah, I don't care "what other people are doing" I have gotten 100k miles so far of reliable daily driving supercharged enjoyment out of my k20. I only raised the rev limiter by 300rpm and I never really go that far anyways, I usually stick to the stock 8300 if I'm winding it out. Other people can blow up their engine or wear them out prematurely revving the nuts out of it on the street.
Love the hybrid chain/gear driven cams. Had a Suzuki TL1000 motorcycle that used the same design, which made removing and resetting the cams easy, which was needed as it used a standard (for bikes) shim under bucket system for valve lash. I noticed the gears are split with the teeth offset a bit. Couldn't see in this video, but in the TL there were springs tensioning the "split" gear to take up gear lash. It had a wonderful gear whine sound. That engine redlined at 10,500 RPM and it made 135 HP at 9,500 RPM. I believe the rev limiter kicked in at 11K. Bikes are awesome. The S2000 engine is quite motorcycle like in some respects.
Something small that I love about your videos is where you put the links for your websites. They're always out of the way, and never block anything that you would want to see. Some you-tubers just slap them up and have them covering stuff you're interested in. You don't do that. Thanks!
Had a 2007. This engine was special, but the transmission was literally the best manual ever made in a production car. Also, whoever put a crummy K&N oil filter on this was a fool. It requires a special Honda OEM filter to survive at 9k. I'm very surprised there are any S2000s that have depreciated to the point of sloppy maintenance.
Another great video Eric! I've learned a lot watching you tear down all kinds of different engines. I know you don't normally do VW/Audi engines, but I'd love to see a blown up VR6 get torn down!
Cool that you could snag one of these motors for a tear down. I owned an 06 S2000 for 10+ years and it was dead reliable thru lots of miles and autocross runs.
As an old gear head who has never torn down a modern engine, I find your tear downs relaxing and very interesting. I've now watched quite a few, and was wondering what would be considered a serviceable/reusable part, like aluminum bolts from a merc bi-turbo, cam gears, "exotic" chains, etc. Thanks for doing a great channel!!!
I remember for a joke, we put my 89 Volvo with the totally stock 2300 and automatic drivetrain. Blew the hotrodders minds when it showed 118 hp at the wheels. Not bad for a 25+ year old tractor motor design. Still strong at 240k miles and no oil burn of note.
If I'm correct, the cams for the vtec in the early to mid 2000 decade were ground at the Mushahi Auto Parts plant in Battle Creek, Mi. That plant made certain gears for Honda automatic transmissions. They were made from round stock, chopped off by a press, forged, lathed and hobbed there, then to heat treat, then shot blast, then final lathing with special cutting inserts in the machines. They shot blasted the gears, but they would have been cleaner and better finished using vibratory bowls, like the Roto Finish machines, but what do I know?
first thing I noticed is that they have the wrong oil filter on it. There've been some reports that aftermarket oil filters can cause issues on this engine due to the OEM ones having been designed for a very high flow rate that the aftermarket ones might not be able to keep up with
My college buddy had a Prelude with the same engine & man was it a fun car! It was a perfect car for school: MINIMAL MAINTENANCE BESIDES OIL CHANGES! He sold it with 350K miles & I was tempted to buy it, but I knew how it was driven & who knew what was left in it. Regardless, it was neat seeing this video as it was a trip down memory lane for sure!!!!
These engines are the closest you can get to having a high strung bike engine in a car. High revving, light, makes good power for size. Pretty sure the s2000 was a nimble chassis as well. Granted our bikes are 200+ BHP nowadays and only .9-1L while revving to 14k+ so not exactly the same, but same idea. Light and tons of reliable N/A power. Very cool engines and cars. Cool to see what makes one tick👍
Yeah, thankfully I got to drive one once when I was working at a dealer. It feels like a small displacement sport bike engine in a way... Meaning if you don't downshift a few gears and rev it out it's not really going anywhere, and the power builds as the revs climb. Very fun car, very reliable car.
Never underestimate the holding strength of Hondabond. Without question it's one of the best RTV's on the market. Thanks Eric for another entertaining teardown.
I was hoping to see one of these! Definitely could have been run low on oil, the F20C in particular is known to burn some oil especially if the driver spends a bunch of time in VTEC. The non-OEM oil filter is a sign that maybe this engine wasn't properly cared for. Another thing to check is the valve retainers in the head, those can crack if the engine is money shifted and a common upgrade is to replace them with the parts from the later F22C. It's remarkable how relatively simple these are considering the power density. Plus as installed in the car they are very mechanic friendly.
Honda seems to specialize in things with way more interior space than they should have (like that oil pickup) and engines that are designed at 90% or more of their ultimate potential that'll run forever if you treat them right.
Love hearing your philosophy on auto makers leaving hp/to on the table. Much respect to the Honda engineers who designed and built this with that in mind.
I literally wear that same sweater everyday at work too lol. I've become known as the guy with the black Milwaukee hoodie on sites. 🤨 Love your videos though, it's always interesting to see a catastrophic failed engine being opened up. 👍
Great to see S2k engine finally! I hope I don't money-shift (over-rev) and destroy my engine. My S2000 is still strong with 250k miles while driving hard (redline every gear) like I ride my motorcycle. And yes, both S2000 and cbr1000rr seem to have same torque numbers...
I enjoy watching you take apart these engines but the one thing I always think is that you must have the most incredible collection of bolts and fasteners in the world
What’s fascinating to me is how there is so many variations of an engine. And how at its core for example a 4 cylinder engine is basically design the same as the next but one outputs more power then the other and so forth. It’s pretty cool to think about how manufacturers all took the same concept and changes it just enough to make it their own engine design even if the concept is the same as the other engine. Mechanics is pretty cool stuff to me. But what do I know. I’m just an IT guy. Haha
i have a f20b the fwd brother to this. I pulled it apart - so different to the c. cam belt, steel sump, oil pump on the front of the crank... so many differences
I have known these engines for years , most do massive mileages at high revs with regular oil changes at 12,000 miles with fully synthetic oil. Like yours I have seen a couple that have been unloved and have black tar in them. The outcome was pretty much the same. Mine at 175,000 miles going strong.
Just wanna take a second to tell anyone who might be curious: the guys at importapart are grade A. Highly recommend checking with them if you're looking for something off the wall, or even something simple. Had an inquiry and response all within a couple hours. They didn't have the specific part I was looking for (headlight assembly for a Cadillac ETC, which are hard to find in good condition), but the customer service was excellent- to the point where they will be one of my go-to places for used parts from now on. Seriously, give them a shot
I had a 02 S2000 with that same engine. Looking forward to seeing what it looks like, and the factory redline was 8900 on it (yes I hit that quite a bit on mine).
22R 22RE 22nd generation of the R series Toyoda family A simple tractor engine not meant to rev but only build torque at low RPMs literally millions built & billions of miles I currently own 4 22R & 3 22RE all with well over 300k miles some over half a million on original long blocks
I recently felt that it was Saturday, that your video was coming, and that I had no beer. Well, too late now. I have never watched this channel sober before.
Crazy thing is these S2K Honda F Engines can handle an insane amount of boost. I knew a guy running ~700 WHP on a stock block, I didn't believe it until he showed me lmao, and it was holding it too! (Not sure if it was a F20 or F22) K series can hold 400 Indefinitely and can go up to ~500+ Stock pretty reliably! Pretty insane for a stock 4 Cylinder!
As a home wrench, I’ve only done deep dives on a handful of engines so your tear-downs are really interesting to me. It’s not hard to see why Honda engines have such a rep for durability. Engineering design and part quality is way closer to what I’ve found in my Porsches than my Fords. Glad to say I’ve been kinder to all mine than were the owners of your ‘victims.’
I always ran Honda Civic oil filters on my Miatas, they were twice a long as the Mazda item but there was plenty of room so why not? Honda stuff is so well over-engineerd I would never trust a K&N filter to do as good a job as an original OEM Honda item, I suspect the blow-up started with the limited flow through the aftermarket filter 😉
love your vids! you got something wrong. the f20c1 horsepower peaks at 8300 and pulls through its 9000 rpm redline so reving these to 9000 is fine. usually they get blown up when somebody miss shifts and over revs them. I only just started watching the vid so maybe you correct this in the video.
Sitting in my RV, parked at turn 15 Sebring Int'l Raceway, enjoying the fine Florida weather. Watching the JP races (new series) and the WEC practices in preparation for next weekends 1000 Mile WEC race and Saturdays 12 Hours of Sebring Weathertech race. But I can't do without my weekly dose of destruction and mayhem courtesy of Eric. Great work as usual. See you next week. (Hey, maybe I can find you a Lambo V10 for a forensic study)
We love it when you disassemble unique engines and not the usual stuff. What we'd really like to see is you import a broken Ford Barra I6 from Australia, they are dirt cheap over there and you'd prob get on for little above import cost. I was over there for Summer Nats in Canberra in Jan and super high hp turbo Barras were everywhere. With few mods those I6s make well over 1000hp, reliably and we'd really like to see a standard one torn down to see what makes them so special and your opinion on them after the pulldown.
It is a sad day to see one of these engines destroyed. Knew a guy that had a yellow AP1 with an exhaust (can't remember which, think it was Spoon) and it had THE best 4 cylinder intake and exhaust sound I have ever heard. Especially at 9,000 RPM. That car was his baby, wish I knew where it was now.
It looked like a 4cyl Cadillac Northstar when you were down to the head and block. HEY! Maybe Cadillac should of built a 4 cyl Northstar!!!😃 All kidding aside, I have always wanted an S2000, look every year but, I just can't pull the trigger. My cousin was a SCCA driver and took me for a ride in one on the Interstate and it was one of the most INTENSE rides that I have ever experienced.
I've never seen a S2000 engine this clearly. That is a beautiful engine.

These F20 series engines are very well engineered, reliable and pretty tough. So to see one blown up like this speaks volumes to how hard this engine was abused. They’re forgiving to an extent, this is what happens when you go over that limit.
Probably missed a downshift and went to 14000rpm for about 0.25 seconds.
@@bradcomis1066 The dreaded ‘money shift’ 💥😭
maybe a track day though no baffles in the oil pan and oil starvation could have caused this also all the stuff in the oil pump meant it was still running after the damage...
Mechanical over spin while going from 3rd gear position to 2nd instead of 4th. If you were to extract the DTC information from the E.C.U., you might possibly find 11,000 RPM failure!
I always love the Honda teardowns, but the F20c1 was a real treat. What an amazing piece of engineering. Thank you for the great video.
I'm a fairly recent subscriber, but love viewing the disassembly videos. Such a relief to watch someone working who really enjoys what they do combined with the gentle humour in the commentary, the first time I heard "disconnecting rod" nearly choked on my coffee. Also a relief to watch a channel that's not trying to sell us everything from VPN's to financial services. Yes of course you've a business to run and promote but it's done in a no nonsense, not shoved down your throat fashion. Love it 🎉🎉👍
I really enjoy you aren't just destructively ripping things apart. You follow the proper procedure to loosen cams, heads and cranks ❤
"This part is in really good shape" [tosses part across shop]...
As someone who drove an AP2 S2000 for 7 years, I found this very interesting. Thanks for sharing it with us.
Never expected this engine! Nice find!
I'm on 122k, I'd be interested if you've had to do any major maintenance on yours in your time- needed to change bearings or anything?
I'm planning on doing rod bearings and valve retainers this year, as a bit of preventative maintenance
This engine is a beauty of engineering - so well designed and built. It must have seen some serious abuse to grenade like that
Looks like about 8000 or so rpm got that one dude
@@g2skinny or a Honda bro decided to remove the rev limiter."yeah bro, my S2K can do 10k RPM easy."
@@g2skinny Stock redline was 9k
Misshift from 3rd to 2nd gear while revving 9k ... How to destroy high revving engines
Generally the bottom end holds together when the F20c is over revved, however the valve retainers are known to crack and cause them to drop valves, which does cause total failure if repeatedly over revved
The way Eric always comments on how beautiful the timing chains are sometimes has me worried about what he does with them after work
There is an enormous used parts market for every part.
@@sat_sonic yeah, I understand that part, but it’s the way he says it that makes me worried about what he does with the chains
Maybe him and his wife like to run a train on the chain? Or maybe it’s a chain bang? Or …..
Self-flagellation?
Ouch.
No kink shaming lol
Wouldn’t even be surprised if this is the old engine from my brothers S2K. He money shifted it on the highway and it totally grenaded itself
You mean he grenaded it lol
@@mediocreman2 pretty much
I used to drive an AP2 S2K. Mine had the F22C1. Such a fun and responsive car. I hate to see them abused like this since they're so rare and beautiful. Thanks for posting this one!
I like how you were like, "Hey! This isn't bad at all. It's in great condition!" Then just launch it across the shop. 😂
I bought a 2007 S2000 that the engine failed shortly after I bought it. The first thing I found was crank end play of .125 and upon tear down I found thrust washers in the pan. Other damage was scored cylinders, three spun bearings, damaged crank, and damaged block. I suspect the previous owner neglected to check the oil level and ran it low. I was lucky to find a used engine for $4500 that came out of a 2007. I really love my S2000, it a thing of beauty to drive.
Your vast knowledge of these engines and their components is amazing, a true technician in every sense. Bravo.
F20 stock ran to 9k. Only the less interesting, but higher torque F22 revved to around 8k.
Most likely this was a mechanical over-rev. Based on the aftermarket VTEC solenoid and the K&N filter, that guy had no idea what he was doing. So no surprise that he money shifted it.
Wow that’s a sad sight. Often touted as one of the best 4 cyl engines … it met a sad demise. Thanks for the tour.
Owned a B18C engine and they are a great motor from a great era.
Rest in pieces F20C1 you will never be forgotten
Eric, with the S2000 engine it was all about NOT exceeding the piston speed, you really didn't want this baby to rev any higher than it was designed too. Things start to go badly if the rev limiter doesn't do it's job correctly. Thanks for showing us this beautiful engine in detail, and thanks for another nice video!
People spin k24's to 9500rpm. Granted they're built
@@brysonshires9742 You can do that with a racing K24, by balancing all of the components and also tearing it down frequently to check your bearings, gaps and tolerances. I advise against doing that to a Built-for-the-Street K24, unless someone else is paying for your engines.
@@ericecklund676 I agree.
@@ericecklund676 yeah, I don't care "what other people are doing" I have gotten 100k miles so far of reliable daily driving supercharged enjoyment out of my k20. I only raised the rev limiter by 300rpm and I never really go that far anyways, I usually stick to the stock 8300 if I'm winding it out.
Other people can blow up their engine or wear them out prematurely revving the nuts out of it on the street.
@@volvo09 I have nearly 100k on my NA K24, in my Honda Accord. It's a fun grocery getter.
Love the hybrid chain/gear driven cams. Had a Suzuki TL1000 motorcycle that used the same design, which made removing and resetting the cams easy, which was needed as it used a standard (for bikes) shim under bucket system for valve lash.
I noticed the gears are split with the teeth offset a bit. Couldn't see in this video, but in the TL there were springs tensioning the "split" gear to take up gear lash. It had a wonderful gear whine sound. That engine redlined at 10,500 RPM and it made 135 HP at 9,500 RPM. I believe the rev limiter kicked in at 11K. Bikes are awesome. The S2000 engine is quite motorcycle like in some respects.
Something small that I love about your videos is where you put the links for your websites. They're always out of the way, and never block anything that you would want to see. Some you-tubers just slap them up and have them covering stuff you're interested in. You don't do that. Thanks!
Had a 2007. This engine was special, but the transmission was literally the best manual ever made in a production car. Also, whoever put a crummy K&N oil filter on this was a fool. It requires a special Honda OEM filter to survive at 9k. I'm very surprised there are any S2000s that have depreciated to the point of sloppy maintenance.
They were pretty damn cheap back in 2009. I bought one for $13.5k USD that year.
Laughs in NP A833
First thing I noticed too. That and the after market Solanoid. This engine was not cared for properly
Being a 2007 low miles AP2 owner, I really appreciate watching the teardown of this engine.
Another great video Eric! I've learned a lot watching you tear down all kinds of different engines. I know you don't normally do VW/Audi engines, but I'd love to see a blown up VR6 get torn down!
Cool that you could snag one of these motors for a tear down. I owned an 06 S2000 for 10+ years and it was dead reliable thru lots of miles and autocross runs.
As an old gear head who has never torn down a modern engine, I find your tear downs relaxing and very interesting. I've now watched quite a few, and was wondering what would be considered a serviceable/reusable part, like aluminum bolts from a merc bi-turbo, cam gears, "exotic" chains, etc. Thanks for doing a great channel!!!
I remember for a joke, we put my 89 Volvo with the totally stock 2300 and automatic drivetrain. Blew the hotrodders minds when it showed 118 hp at the wheels. Not bad for a 25+ year old tractor motor design. Still strong at 240k miles and no oil burn of note.
If only you would have removed that sweet k&n oil filter and cut it open to see how well it did or didn't work.
Wow as an s2000 (AP1) owner to b specific it is a treat to see how my motor looks , thnk u .
Dammit! No dipstick foibles. Excellent engine for teardown. Cheers and thanks 👍
We love the carnage!! Thank you!! Keep up the good work!!
Always enjoy watching these tare downs! Engines I've never had the opportunity to work on.
If I'm correct, the cams for the vtec in the early to mid 2000 decade were ground at the Mushahi Auto Parts plant in Battle Creek, Mi. That plant made certain gears for Honda automatic transmissions. They were made from round stock, chopped off by a press, forged, lathed and hobbed there, then to heat treat, then shot blast, then final lathing with special cutting inserts in the machines. They shot blasted the gears, but they would have been cleaner and better finished using vibratory bowls, like the Roto Finish machines, but what do I know?
first thing I noticed is that they have the wrong oil filter on it. There've been some reports that aftermarket oil filters can cause issues on this engine due to the OEM ones having been designed for a very high flow rate that the aftermarket ones might not be able to keep up with
My college buddy had a Prelude with the same engine & man was it a fun car! It was a perfect car for school: MINIMAL MAINTENANCE BESIDES OIL CHANGES! He sold it with 350K miles & I was tempted to buy it, but I knew how it was driven & who knew what was left in it. Regardless, it was neat seeing this video as it was a trip down memory lane for sure!!!!
These engines are the closest you can get to having a high strung bike engine in a car. High revving, light, makes good power for size. Pretty sure the s2000 was a nimble chassis as well. Granted our bikes are 200+ BHP nowadays and only .9-1L while revving to 14k+ so not exactly the same, but same idea. Light and tons of reliable N/A power. Very cool engines and cars. Cool to see what makes one tick👍
If you want the bike engine in a car experience that's what the Mazda rotaries are for.
Much love my brother, reminds me of the show "Scared Straight". Finding out what that little red line on the tack means can be very expensive.
Id love to see a teardown of the Volkswagen 5 cylinder 2.5L motors from the previous generations of Golfs and Jetta, do you see many of those engines?
And the VW VR6 engine.
There are plenty of those videos out there…
That oil pan design itself shows how well Honda built this engine !
One of my favorite cars! That motor revs like crazy but you can drive it like a civic. Hope to own one again someday
Yeah, thankfully I got to drive one once when I was working at a dealer. It feels like a small displacement sport bike engine in a way... Meaning if you don't downshift a few gears and rev it out it's not really going anywhere, and the power builds as the revs climb.
Very fun car, very reliable car.
This engine was designed to run at high RPMs, but with any I.C.E., the more you rev it, the more likely you are to damage it. Great video!!!
This is where the quality of your oil choice really plays a role, most of these owners use cheap mobil1 and etcetera! Trust me!
There is cheap mobile 1 oil? I run full synthetic motor oil on my s2000...
Something about this channel makes me want to check my oil every Saturday.
And change it every other Saturday
Never underestimate the holding strength of Hondabond. Without question it's one of the best RTV's on the market. Thanks Eric for another entertaining teardown.
I really miss the simplicity of those engines compared to what’s out now plus the good reliability.
I’ve always wanted to see inside of a blown up s2000 engine. Well done sir!
I was hoping to see one of these! Definitely could have been run low on oil, the F20C in particular is known to burn some oil especially if the driver spends a bunch of time in VTEC. The non-OEM oil filter is a sign that maybe this engine wasn't properly cared for. Another thing to check is the valve retainers in the head, those can crack if the engine is money shifted and a common upgrade is to replace them with the parts from the later F22C. It's remarkable how relatively simple these are considering the power density. Plus as installed in the car they are very mechanic friendly.
Such an incredibly simple yet well engineered engine, yet it makes so much power. Honda makes the best motors in the world.
Honda seems to specialize in things with way more interior space than they should have (like that oil pickup) and engines that are designed at 90% or more of their ultimate potential that'll run forever if you treat them right.
Happy Saturday! Really intrigued to see this one.
K&N filter killed it for sure!
what’s wrong with them?
Love hearing your philosophy on auto makers leaving hp/to on the table. Much respect to the Honda engineers who designed and built this with that in mind.
Almost 2 hp per cubic inch. Impressive
As impressive as a CBR125?
@@Benzyl no. Cbr125 only has 1.75 hp per cubic inch, and only has a total of 14hp.
I literally wear that same sweater everyday at work too lol.
I've become known as the guy with the black Milwaukee hoodie on sites. 🤨
Love your videos though, it's always interesting to see a catastrophic failed engine being opened up. 👍
Great to see S2k engine finally! I hope I don't money-shift (over-rev) and destroy my engine. My S2000 is still strong with 250k miles while driving hard (redline every gear) like I ride my motorcycle.
And yes, both S2000 and cbr1000rr seem to have same torque numbers...
Gooney....your luck will run out! Most likely through the side of the block.
I enjoy watching you take apart these engines but the one thing I always think is that you must have the most incredible collection of bolts and fasteners in the world
What’s fascinating to me is how there is so many variations of an engine. And how at its core for example a 4 cylinder engine is basically design the same as the next but one outputs more power then the other and so forth. It’s pretty cool to think about how manufacturers all took the same concept and changes it just enough to make it their own engine design even if the concept is the same as the other engine. Mechanics is pretty cool stuff to me. But what do I know. I’m just an IT guy. Haha
i have a f20b the fwd brother to this. I pulled it apart - so different to the c. cam belt, steel sump, oil pump on the front of the crank... so many differences
I have known these engines for years , most do massive mileages at high revs with regular oil changes at 12,000 miles with fully synthetic oil. Like yours I have seen a couple that have been unloved and have black tar in them. The outcome was pretty much the same. Mine at 175,000 miles going strong.
Loved this. I owned 2 S2000’s back in the days before I had kids. An ‘01 AP1 and an ‘04 AP2. Wonderful engines, wonderful cars.
Just wanna take a second to tell anyone who might be curious: the guys at importapart are grade A. Highly recommend checking with them if you're looking for something off the wall, or even something simple. Had an inquiry and response all within a couple hours. They didn't have the specific part I was looking for (headlight assembly for a Cadillac ETC, which are hard to find in good condition), but the customer service was excellent- to the point where they will be one of my go-to places for used parts from now on. Seriously, give them a shot
I would love to see a W12
I second this!
It would be a 17 part series but I bet it would be fascinating too.
I like how you disassembled this one like "Come on. Old Gill really needs these parts."
Wow good find! Definitely not common
"I don't think it has any rod knock, but it may not have any rods" Love it!!!!😀
I miss my S2000's, both of them, a 2002 and 2006.
I had a 02 S2000 with that same engine. Looking forward to seeing what it looks like, and the factory redline was 8900 on it (yes I hit that quite a bit on mine).
My favorite part is always when you say”oh, this is in pretty good shape”, then unceremoniously toss it… somewhere. It’s no longer in good shape. Lol.
This is a wonderful video.
would love to see a 22re teardown🤞
Yup yup. That’s another good one. Agree.
What a loyal engine those little guys were. I miss my little Hilux.

I recently felt that it was Saturday, that your video was coming, and that I had no beer. Well, too late now. I have never watched this channel sober before.
When the VTEC kicks in yo’
6000k
Crazy thing is these S2K Honda F Engines can handle an insane amount of boost. I knew a guy running ~700 WHP on a stock block, I didn't believe it until he showed me lmao, and it was holding it too! (Not sure if it was a F20 or F22) K series can hold 400 Indefinitely and can go up to ~500+ Stock pretty reliably! Pretty insane for a stock 4 Cylinder!
Wow those are rare to find! Let’s do a 1.4T Multiair Fiat engine next!
Reminds of my 2001 s2000 man I miss that car!
The dreaded money shift... the F20C can hang at 9000 rpm, but not in 2nd gear at 80 mph.
As a home wrench, I’ve only done deep dives on a handful of engines so your tear-downs are really interesting to me. It’s not hard to see why Honda engines have such a rep for durability. Engineering design and part quality is way closer to what I’ve found in my Porsches than my Fords. Glad to say I’ve been kinder to all mine than were the owners of your ‘victims.’
I always ran Honda Civic oil filters on my Miatas, they were twice a long as the Mazda item but there was plenty of room so why not? Honda stuff is so well over-engineerd I would never trust a K&N filter to do as good a job as an original OEM Honda item, I suspect the blow-up started with the limited flow through the aftermarket filter 😉
love your vids! you got something wrong. the f20c1 horsepower peaks at 8300 and pulls through its 9000 rpm redline so reving these to 9000 is fine. usually they get blown up when somebody miss shifts and over revs them. I only just started watching the vid so maybe you correct this in the video.
Sitting in my RV, parked at turn 15 Sebring Int'l Raceway, enjoying the fine Florida weather. Watching the JP races (new series) and the WEC practices in preparation for next weekends 1000 Mile WEC race and Saturdays 12 Hours of Sebring Weathertech race.
But I can't do without my weekly dose of destruction and mayhem courtesy of Eric. Great work as usual. See you next week.
(Hey, maybe I can find you a Lambo V10 for a forensic study)
Too much NOS not enough VTEC...
Love how high revs this engine would do. Great car.
I gotta say...overlooking the destruction...that is one seriously beefy engine design.
We love it when you disassemble unique engines and not the usual stuff. What we'd really like to see is you import a broken Ford Barra I6 from Australia, they are dirt cheap over there and you'd prob get on for little above import cost. I was over there for Summer Nats in Canberra in Jan and super high hp turbo Barras were everywhere. With few mods those I6s make well over 1000hp, reliably and we'd really like to see a standard one torn down to see what makes them so special and your opinion on them after the pulldown.
When a fool believes "bouncing off the limiter" is a display of performance...this is the result.
I wish Honda made an inline 6 version of this engine (or the K series). That would be awesome!
It is a sad day to see one of these engines destroyed. Knew a guy that had a yellow AP1 with an exhaust (can't remember which, think it was Spoon) and it had THE best 4 cylinder intake and exhaust sound I have ever heard. Especially at 9,000 RPM. That car was his baby, wish I knew where it was now.
Seen this engine featured on jay lenos garage. Nice to see the tear down of it as well. Remarkable engine
It looked like a 4cyl Cadillac Northstar when you were down to the head and block. HEY! Maybe Cadillac should of built a 4 cyl Northstar!!!😃 All kidding aside, I have always wanted an S2000, look every year but, I just can't pull the trigger. My cousin was a SCCA driver and took me for a ride in one on the Interstate and it was one of the most INTENSE rides that I have ever experienced.
Intake ports look amazing given everything the engines been through. A beautiful engine to look at and review.
I learn so much from this show
Glad this popped up cuz I just blew my engine yesterday going from 4th to 3rd on the highway luckily mine has no holes or oil leaking out
