***this is mostly about performance application. for people who plan to just daily the car bone stock there is still good information explaining why it wont last like the old engines**
This is a video break down about why Hondas l15 turbo engine is the worst engine they ever made. horsepower and mpg are only one part of what makes an engine good. With the l15 the reliability is thrown completely out the window. Gone are the days of maintaining a honda and getting 300-400k no issues.

I'm a race engine builder for primarily Honda engines and these are just my opinions based on the l15 from experience first hand. I've changed countless of these at my shop from stock to built. This is basically a heads up for anyone about to purchase a car with a l15 or that currently owns one to be careful. stock you should be able to clear 100k miles driving normally, if you want to mod it and push this engine you are on you're own. you've been warned!

These have proven to be at least as reliable as anything similar when left stock and well maintained. They’re more reliable than say the GM 1.4T that’s plagued with problems. Cars are changing in many ways and Honda is adapting. There are many other things to like in the current gen cars and a huge number of these engines out there. Most owners have had zero real world problems short of the fuel dilution in the early CR-V in cold climates taking short trips. The next gen Hondas will likely be EV’s or hybrids that will be even less suitable for mods. My advice is to enjoy the 1.5t in stock form and know you have a solid powertrain warranty you likely never need.

What the L15 engine is and isn't is not a secret. It would be like a VW person trying to tune the 1.4L EA211 instead of buying a car with the EA888 in it (be it 1.8L or 2.0L EA888). By all means you can tune EA211 engines, especially the twincharger ones in the Polo GTI, but expecting them to hold the same power as a EA888 or EA113? Obviously that's just not going to happen.

@@TassieLorenzoHere’s where your argument falls off. No one expected to the K series engines to be as tough as they are. They also started in econoboxes until people started experimenting with them. That’s how these engines got the aftermarket to begin with. Experimenting. The fact that a D series crank is much beefier shouldn’t excuse Honda from making a flimsy crank for the L15. VW overbuilt the 2.slow to high hell with forged internals and all. Obviously, going this route ensures engine reliability at all speeds.

@@infiniteblaz3416 Good points! The Integra and Civic Type R were very good econoboxes (not so much the awful Honda Stream suspension) and it's certainly true the K series has some cost-cutting/friction-reduction from the S2000 engine like narrower big end bearings, the two cams aren't connected by an idler gear anymore etc, yet it is popular anyway. The K series did originally come with the exact same valve springs as the S2000, which was good of Honda despite a slightly lower-revving engine, and the intake VCT soon proved it's usefulness!

But then you can say "but Subaru can do it", they have the inefficient FA24 in the BRZ (now just as good as any K24?) and the inefficient FA24DIT in the WRX and that seems to be fine. I dunno.

In fact, I averaged 44 MPG last tank and I haven't even started tuning it for fuel efficiency yet other than my taller 5th and 6th gears.

I had a 99 si, and the b16 is a great engine. I had a 22 si, and I could tell right after I broke the motor in that the car wasn't designed to be driven like my 99 si. Not to mention quite a few times, when I was in traffic, I could see wisps of steam hitting the wind shield. The hood was always so damn hot. The l15 always seemed to be struggling, I absolutely refused to throw a hondata on there. Needless to say, I traded it in for a fl5 type r and couldn't be happier. After a 6 hr. drive home from purchasing my type r, the hood was cold. I understand this isn't an option for everyone, my suggestion is to get a low mileage older si that has a k-series engine if you plan on tuning it. This will cost less than a brand new si. The l15 engine is a gas saver, it's not meant for tuning or even hard daily driving. Thanks for the video my guy, you solidified in my mind why I got rid of the car.

I’ve had a 2004 Lexus RX330 and daily driven it hard. The engine and transmission never skipped a beat. The 3MZ-FE is a V6 engine built for fuel economy but, can really take a beating. It’s pretty much just a piston in a cylinder compared to those new fangled turbocharged and downsized engines with questionable reliability. The 2GR-FE is more powerful, more efficient, and reliable than the 3MZ engine. For the price of a new Civic SI, you could pickup a used V6 Toyota Camry or V6 Honda Accord. Mash on it to your hearts content as long as you change the oil every 5k miles and ATF every 100k miles, you will never have problems.

The 2.0t accord is also another option, since is also comes in manual, and essentially has a detuned k20 type r engine.

For a k20c4 would be the same as a k20c1. Around 400tq would be the max. Also depends how it comes in. A stock turbo maxed out will bend rods faster then a big turbo with more tq on the top end of the rev range

Not being ideal for racing does not make it "the worst engine Honda ever built". Proper maintenance and conservative driving habits its as reliable as anything Honda has ever built. They did have some issues with fuel dilution, and I'll agree if you want to race something this is not the engine you want to use, but as a stock, daily driver it's a good motor. I have a 2019 CRV with 100,000 miles on it and have had 0 problems out of it, nothing but standard maintenance. I did see some rising oil levels due to fuel dilution, but switching to super fuel has stopped that. Runs great and gets great gas mileage. The CVT gives me some concerns, but I've saw plenty of these transmissions with 200,000+ miles. You just have to take care of it. Racing is not taking care of it. Not a knock on your video, just found it a bit misleading.

Damn I have an 11th gen Si and yeah it was very hard for me to decide which car to get because of the specs. My first car was a 2007 Toyota Corolla S and I always wanted to drive manual (Mind you I'm 21). Being that I also wanted to build my credit more besides just using credit cards, I figured getting a new car would be best for me to do that so that's why I then even looked into new cars. I had my eyes on the 10th & 11th gen Si and the 2022 GR86/BRZ. I saw and heard how I believe it was Hondata made a video comparing the regular 11th gen civic and 11th gen Si and after watching your video. It totally makes sense how the Si is legit the same engine but before they put it in, they just change the tune so it ends up being the same either ways. I do/don't regret getting my Si let's say over the regular 11th gen civic or the other cars just because I bought it knowing I'm going to keep it stock, good on gas, turbo'd, and again it's manual. So as a daily standpoint I can't complain which you were right about from the beginning if that is what you plan on doing with the car anyways. TBH, it's not like I ever race anyone either (like as if anyone even tries to race me lol which they don't and don't blame them since I'm slow). I just liked the fact that I can have fun on backroads and stuff like that so. If it was that I wanted to build a street car, I've always had my eyes on the 2008 Civic Si's or the 2006 RSX Type-S's just bc of the K20's but for the sake of wanting to build credit, I figured sure I'll just get a newer car. Besides Honda's hold their value so I'm sure I'll get a decent return for when I sell it down the road so that if anything, I can always buy one of those cars I mentioned with cash and build it. But I appreciate the information, very informative, and would highly recommend anyone reading this that if you're going to be buying/getting a new car for yourself (old/new), buy it because you like it and that it makes sense for you. Just make sure you set the right intentions for yourself about the car like what's it for (Race? Street? Dailly? All-around?), budget, and etc,.

First of all, don't use Lucas or any other oil additive.

It won't make the crankshaft stronger, it won't keep you from blowing the head gasket, it won't strengthen the rods or their bolts, it won't address the oiling issues, etc. The only thing it might do is provide slightly better protection if you get fuel dilution since an oil that starts out thicker will remain thicker once thinned by fuel, but that's about it.

Your assessment and OPINION as well as your experiences of these engines and there potential failure points when TUNED is pretty on point and great advice. As a 22 year Honda tech I have seen all the failures I think, but the most common on these 1.5's are head gaskets and that's a stock config. These things were over engineered for the least amount of friction and weight as possible to get good fuel economy, that's why when its -30 out they never warm up as there's no friction in these things. I beat the hell out of my B16a and had zero issues, I also have an 18 Si and drive it hard as well and no issues but i suspect i might seeing the current trend, and no I have no intentions of modding it. The only thing i disagree after watching this is you comparison between the L15, K series and B series... they are three totally different engines in all aspects, so comparing the con rod bolts and head bolts is the same as me comparing con rod bolts from my 01 Insight to my friend 94 Mustang, makes no sense. I never noticed the oil galleys on the cranks as I have not had to pull one yet but that's interesting. Every Honda engine has its faults that could be considered the worst, but I am getting rich on timing chains in K series that's for sure and I think that's the worst engine IMOP but the best for mods by far like you describe. . Best engine for reliability and lack of any issues of any kind for me would be the 1.8 SOHC(06-15 Civics's ) and the B16 series :) Thanks for the breakdown

I don't disagree with anything in this video. The comparisons are spot on. Honda obviously wanted to reduce mass and skimped where they could for fuel economy. But... A company I have an interest in does document oriented courier work. There are 6 Honda CR-V's that are 2017 and 2018 models. They will haul 10 to 20 document boxes to and from various places all over the state for legal and financial firms. Each have a custom Hondata tune oriented around fuel economy. They run 93 octane and get synthetic oil changes directly from the dealer. The CVT gets Amsoil every 30k to 40k. No major issues and they range from 150k to 250k miles. Granted, they are almost exclusively highway miles, but for average use, I think the design is fine. But I 100% agree that tuning these engines is a fools errand.

Not good enough, so I bought something else. At the same time, my son was looking to buy a new Civic. I warned him against getting the L-series 1.5 turbo.

I would like to testify to my many problems encountered with my Civic 2020 Sport Plus with the 1.5T L15BA engine in France. I bought this car new in February 2020 with 0km. Currently I have 20000km (12500 miles). According to Honda France, my Civic was not affected by the fuel pump problem but unfortunately no brand recall. And indeed I had power loss and idle problems. The pump had to be changed at 16,000 km (10,000 miles). I'm not talking about paint problems on a rally red on the rear bumper. But even more serious when I realized a little late that my Civic was drinking coolant. The maintenance garage didn't know where it was going. So we were regularly filling up the expansion tank, until one summer day this year when it was particularly very very hot, the Civic found itself in extreme engine overheating. The Civic had starting problems and seemed to run on 2 or 3 cylinders. The garage still did not ask questions, despite my concerns. So he refueled and 500km (300 miles) later, the jar was empty again. The garage therefore decides to open the engine in 2 and was able to see that my cylinder head had a big molding problem from the factory. So since buying my Civic, my 1.5T engine was drinking coolant through cylinder 2 and smoking white out the exhaust. The cylinder head had to be changed at 19500km (12200 miles). Since the idle is not terrible and I like tremors in the engine. Unfortunately, I no longer trust this car and Honda. I have problems reselling it because of this defect and Honda France doesn't care !

@khoadinh4120 Yeah, it's been good to me. I don't mind the work but if your not inclined to repair it yourself then I'd caution against the tuning and modifications. The car was never dyno'd and was tuned with an Etune, which leaves you with a good running vehicle, yes. But you don't get all that data you would from say a dyno tune. Guessing wise and based off others with similar parts and from the same tuner, I think it was closer to that 280/300 hp line, i was pretty maxed out with my fuel system. So the tune has 3 stages of settings. The turbo psi being the difference in those settings I believe. So, I drove it mainly on #1 the lowest of psi, with an upgraded turbo of course. I would play around with #2 settings and it felt good, #3 would have me laughing and kinda to that point like " wow, I shouldn't probably be driving it much at that setting." That could of just been me though. The Hp and torque, I'm guessing was 280 to 300. I was close to my fuel systems max and my tranny was too based off the heat gen. If you have driven a car for this long and this far, you monitored it stock and tuned, you know the different data points well enough. I can tell based off my heat generation within the cvt if I got more room or not. It didn't, but it did not overheat if I knew when I could push it. And when not to. It's funny because you work so hard fighting the engine heat soaking, new fmic allows you that head room, turbo blankets help to minimize that radiant heat build up, but that whole time the heat starts to shift from a problem in engine heat soaking and now it's heat build up in the tranny fluid lol. It's like you trade it off , but thats just how I felt.

First off it doesn't matter if it's hondata it ktuner. Those are just programs. L15s safe range is 250hp 250tq Sure it can hold 275-280 tq for a little but once you pass that 300 mark rods start flying. All that being said I've actually had a few come to the shop that blew up stock. Overall the internals are just very weak. The minute you put a tune on it you know what your signing up for. A stage 1 tune and taken care of should last a decent time but there's always that possibility. Overall it's a stupid platform and better off trading out the car for something else if you want to mess with bolt ons and tunes

He knows his engines no doubt but that doesn't mean his word is gold. 73k on 300tq pushing 26psi since 30k. No issues. Every rod he showed and all the stories of oil on the track on a stock engine are the result of a money shift. It's easy to miss a gear. Cheap gearbox with a tight grid. I bought mine new. I can speak from experience. Enjoy your SI. It's worth every dollar and then some.

I got a 2020 Si TSP stage 1+, PRL Cobra CAI (Street MAF), MAP Catted downpipe, PRL intercooler and charge pipes. Upgraded the clutch to ACT street clutch after blowing out the stock one. I'm driving daily on map 2 (21psi) and more recently map 3 (26psi). I try to ease into it if I go WOT but I definitely get up to 24, 25psi pretty often. Car is just under 40k miles. Would you say I'm running on "borrowed time?" I don't know my exact hp or torque numbers but the tune is 248 whp and 290tq with stock equipment so I assume Im more like 260hp and 300tq with the bolt ons I have installed, but that's a guess. Just looking for your opinion I can tell you know your shit. Would appreciate a reply, I'm loving the car honestly (its my first manual) but what I've heard people talk about these cars and those fucking rods scares me.

You couldn´t expect in the past to have a 182 CV car with this fuel consumption.

Those small safety margins are pretty disappointing, especially for something designed for a sporty car Honda knew people were going to modify and drive hard. I'm not seeing the advantage of this engine over the older ones either. If they were actually significantly more fuel efficient maybe I could accept the reduced durability as an unavoidable trade off, but that doesn't seem to be the case. I'm getting 40+ MPG out of my K24A2 swapped 04 Civic with the same or more power, no turbo lag, proven reliability, and huge tuning potential, so I fail to see how this is an improvement in any way other than probably being cheaper to manufacture and slightly lighter.

Honda was forced to design their cars with the EPA fuel economy formula in mind. One of the problems with the formula is that it takes into account the size of the vehicle, basically the bigger the car the lower the mileage requirements, it’s why we don’t have small trucks anymore. Then I think there’s a displacement part to the formula too, anyways I suspect they were wanting to meet the demands of the consumer while meeting fuel economy standards… so we get this crappy thing in the end that looks sporty.

@@Kennys_World I agree. It's completely ridiculous how we use increasingly giant cars and trucks as the "solution" to efficient and environmentally friendly transportation and even more ridiculous that the EPA has been allowing this to go on for decades under multiple administrations instead of simply revising their formula to favor smaller and lighter vehicles for actual improvements in efficiency and emissions.

@@cabojacks5106 I never said they should build the engine to be modded, I just said that I don't see any benefit of this engine over the K series. Also, right, wrong, or indifferent, a lot of people who buy cars like Civic Si's are going to modify them and manufacturers know it. It's definitely not the fault of the manufacturer if someone causes a problem by modifying something, but when a manufacturer installs an engine with such little tuning potential compared to previous engines in an enthusiast model, people aren't going to be thrilled with that, especially since there's no major benefit to the customer that I'm seeing.

I believe you are on to something. Honda has already pushed a recall for the 2017-2020 CR-V's with the L15BE (1.5t engine). The Accord 2017-2022 (1.5t), and Accord 2023-present (1.5t non-hybrids), 2017-2022 Honda CR-V, and 2023-current Honda CR-V's use this engine still. Honda says they have corrected the issue in newer versions of the L15BE. But if there are issues with the engine NA, just imagine throwing a Turbo on it will just shorten the life of the engine even more. If the customer changes the oil at ever 5k miles that seems to be a good idea anyways but may mitigate some of the oil dilution issues seen. But I highly doubt these engines are good up past 150k, due to adding the turbo to them. The added heat alone will shorten the lifespan of a really well engineered engine. So I seriously doubt someone buying a 1.5t Honda engine expect it to go 200k plus. Most owners are good if they can get over 120k out of a stock engine and transmission when a turbo is involved. On the recall Honda has issued a limited warranty on those parts, nothing sizeable to make customer feel like Honda is going above and beyond. I wonder how many customers saw failure of their L15BE outside of the factory warranty, paid a pretty penny to get them repaired before Honda did the recall. I think we would call the ex-Honda customers. Don't get me wrong I have had really good Honda's, and this video just drives home the need to stay away from any of the 1.5t engines from Honda. Also I am choosing to go with a 10th gen 2.0t Accord as my next car. Very similar built engine to the Type-R, but not same internals or Turbo. Also the 11th gen Accord is a dud to me. Thanks for the video.

Is most of the issues at the 300 mark from stock internals? Im building a forged L Series in the UK, L13z1 (1.3, shorter stroke) but sourced a CRZ crankshaft with K1 Connecting Rods and Wiseco 10:1 Pistons to up the stroke to the same as the L15 (I kept stock compression as im not turboing straight away) In your opinion is below 250 hp with a built block unreachable? I'm aiming for 220 to the wheels. Mines a Fit engine so not the B7, but shares most of the same design aside from using port injection. And with regards to the crank are ARP main bolts a must? Ive avoided getting them and hoping to stick to just uaing their head studs as from what i understand it needs another line bore due to the extra torque needed on the bolts.

I never slam the car into gear, I wait until after I select the grear engages before applying the gas forward or reverse. I start the car and wait until the tack goes down to around 1,200 t0 1,500 Rpm before putting it into gear, the shifting is so smooth I never feel a change. If one drives like that, you mean the CVT wont last 200,000?
