So... are you a K-series or a new-school L-series lover?
The background music makes it difficult to hear you. Disappointing.
Money vs power gains on L15 vs K24 has absolutely no discussion, you guys should be working on the k20C4 - k20C1 platforms with the same interest
@@amiloooo meh, just give it time for the market to catch up.
K series with boost ftw
R18 > K20C2 > L15B7
K24 all day. The new 1.5 and type r engine have a lot of catch up to do aftermarket wise
The type R is K series.
Chintzy made too
K is the way…
So much info in this video , great content
Glad you enjoyed it!
K-series will always be my to-go swap.
Great video!, Love the L15B can’t wait to see the future potential with these motors.
There isn’t to much potential out of them at 40 PSI of boost on a built block your sitting at 480-490’s now that’s on a Motec with port injection. Maxing out the GTX2867 Gen 2 you may be able to squeeze another PSI or two but really strain that turbo. Also at that power level the motor won’t last over 25K everything about the motor is built for ego not power.
They are not good. The lack of vtec on the intake cam hinders them greatly. I have an article saved on my pc about this issue on boosted applications. It took me 3yrs to figure if the k20c1 and l15b7 would suffer from this and the indeed do! Pm me if you want the article.
Honda drop the ball on the L15 engines.. They are weaker then hondas old D series engines.
@nezabytes ayo, i got a totaled 2016 civic sittin pretty with the engine at aroud 42k miles, know what chassis i should be looking for?
Good 👍 ASS job Brudda ✌. Very informative..
I have a k24 swapped 2008 si 🤩
I love my 1.5t civic Si but my dream project is to build a dc2 and k20/24 swap it.
Im thinking about swapping my 2.3 liter mustang with a K20.
@MAPerformance What would you suggest for an 8th gen Si? I have an FG2, and a 95 DC2. My thought was to pick up a newer civic out of auction and take the L15 into the FG2, and swap the K20Z3 into the Integra and go turbo for a daily driver. I want the Si to be my track car, and a goal of 300-400 HP would be my goal there.
Might be too early to say but i feel like the small displacement of the l15 really hinders its potential for tuners. I dont know if they really are but i feel like the k series are built better
These days, size doesn't matter much for tuning. 1.5 in gr yaris is being touted as the next 2jz. Give the l15 time.
@@cyberloki4737 no replacement for displacement, it surely helps in the early stages and longevity of the block. On the same note i remember people pushing 800hp with the smaller b16/18 engines
A lot of reliability issues in the L15B7 1.5L turbo engines are in the crankshaft flexing under higher heat and pressure and connecting rods being too thin (which look like pencil rods, it's pathetic). K20 and K24 engines, while more highly reliable and infamous (in a good way) for making ridiculous power, have issues of their own. People with K series engines that are heavily modified for high horsepower should expect problems with overheating, front and rear main seal leaks due to high pressure in the crankcase, excessive camshaft lobe galling, excessive motor mount vibrations, etc. The trade off for more power is less reliability, really.
I am going for a somewhat budget build. I am thinking of doing one of the older l15A series found in the 2nd gen fit. Or id go with a k20/24 frankenstien build. Im trying to do soemthing more unheard of swapping it into a 2nd gen Insight.
As a daily driver I prefer my older k24 to my newer l 15.
Turbo lag is very aggravating!
Especially pulling out into traffic!
Is that the K20 or K24 that holds mid 800whp on stock bottom end ?
I own a 2009 crv k24 and a 2018 SI L15. And honestly. I still love my crv to death. Something bout the n/a engines I really love.
Haven't a ton of the L15's blown up? Even many with 300 and under?
I want an L series car like the Fit, but keep it NA and just do some stickies, good pads, perhaps some nice wheels (Watanabes would be sweet) and a sport muffler (either HKS or Spoon). Now for a Honda bike I want an NPS-50 for that GET engine, and a Hotlap pipe (keep the baffle in) and perhaps a drop in filter like a K&N for the stock airbox because I don't want to have to do crazy jetting or deal with lost low end. Neither would be "actual fast" but would sure feel fast because both are small and fun to toss around due to a rigid frame and light weight.
Fits are the best!
I was thinking about doing l15 swap for a 2010 honda fit. Smaller displacement that would yield great power with oem level mpg? I want a daily comuter that is also a sleeper with 300hp ?
Go for an LEA from a CRZ with the hybrid unit. I'd look into project hycaei that TDI North did a few years ago, near 300hp and 50 mpg
I would like to see the f20c1 and f22c1 from honda s2000’s since that’s what i have
Honda's L15B7 is highly NOT recommended for re-tuning or modifying for more Horse Power "HP" and torque. 180 to 205 HP is what the engine is designed for, not drag racing or as a small race car. If the maximum is 300HP, why spend the money only to have the engine blow up? Therefore, don't mess around with the L15xx engines. Find something else.
This video is setting up some unrealistic expectations for the L15
I want to do an L15 swappp in my EF civic wagon 2wd.
I’ve always liked j series 06-07 accord
Honestly...i dont see a lot of tsx (by that i mean 04-08) around that are modified...I'm more for how the car looks and sound so i dont play too much around with the car to make it unreliable
I would take a turbo d series over an L series anyday
What is dry weight of l15?
I’m trying too get a 10th gen si for track and canyon so lookin for around 300 am I still good in the Honda reliability with these numbers?
Yes just gotta get a new clutch basically instantly
K series the way to go for high power and reliability. I have an L15 that's stock at 280k Miles. Will be looking into k swap when this engine fails
1.5 liter the MR2(Boxster)
If I want to make 300 HP in my L15 FBO with stage 2 clutch and stock turbo is that safe or too much stress on stock turbo ? Also would you recommend the MHI turbo upgrade ?
Youre good my dude. Anything above 300 with the stock turbo is where youll get headaches
Don’t waste your money on a similar sized turbo, if your going to upgrade go bigger you’ll get more top end gains I have a Garrett from prl on mine I don’t even run e just 93 and make really good power. You can easily make 300 on stock turbo though. It’s the torque that kills so have your Tuner dial it down under 4K rpms
If you want to be extra safe, don't go 300 with the stock one, 270-80 is fine. If you want safety for over 300,either change them all together (turbo, intercooler etc) and then fine tune it, or if you don't have the cash yet start from the intercooler and a chip tuning
All I want is like 250 to 270 hp in my 2020 si sedan. I'm 40 years old I don't need the speed I've gone 150 plus. So I'm good there I just want the extra pep lol
@@XeroFailGames me too man
How much money does an L15B7 cost in the states, we have an L15BA engine in our UK 16> Civic's but word on the street is they are not as strong as the B7 in the SI ?
It all depends on how much horsepower you're trying to make. If you're going to stay around 500hp. L15b. If you want to make closer to 1000 horsepower then go with the k24. No replacement for displacement. I got a j30T.
It cost so much more the get an L15 to 500 then it does a k series…
L15 to 500 requires, built block, upgraded turbo, completely upgraded fuel system, upgraded clutch… and if your using said L15 in the chassis it came in you’ll need to change the front brakes to get a wheel on there that can fit a decent enough tire to make that power even usable…
And then you still don’t even have a hand brake to aid in preloading the driveline…
K series, add a cheap turbo kit and call it a day…🤷🏻♂️
Lol how many people realistically do you think want to make 1000 or even 500 hp? Get outta here
@@jacobdicicco2044 probably a lot more then you realize… lol
@@Serpentis666 as someone who had a k20 and now has a L15, they’re definitely different but it doesn’t cost much to make good power out of it cost less to build one than getting a type especially in this market, eBay turbos for k series are sketchy as hell that’s a B series thing and the “budget kit” for k series to make 500hp from humble performance is $5000
@@MiguelGonzalez-vr1fe as someone who’s had multiple k series cars… and a 10th gen si with every bolt on and flex fuel…
Your absolutely incorrect…
The most you can make on the cheap with an L15 is less then 300…
The fuel system can’t handle it…
The rods also can’t handle it…
The humble kit is a decent offering… but you have to be oblivious to not see all the used turbo kits and parts for sale daily for k series… if you can’t put together a decent turbo hit for 2000-2500 you really deserve to pay full price…
I wanted to like the L15… I really did…
But having experience with the previous series of Honda engines I was very happy to go back…
You’ll see….🤷🏻♂️
Can you guys provide some insight on the idea of doing a k24w swap on 10th and 11th gen civic Si? There is nobody doing it yet and no information on the concept
Anything is possible with enough $$$! You'd need a lot of custom mounts/work to do so!
@@maperformance money I got just need R&D
I saw on RUclips a 10 gen Si with a K20C from an accord or type R can't recall exactly.
@@alexvela291 ya not a 11th gen
My shop forman at the dealer I work at swapped a k20c4 in a 19 civic SI .
Wonder how turbo k20 would compare to k24 turbo?
For some reason, most people turbo a K20.
I would like a 320 hp type r swap in my civic eg and put the current b16a2 in something light and fishy. Perhaps in an old mini or a 1996 miata
Would be disgusting
So the eg is heavy?
@@Serpentis666 lol of course its not, just 1090 kilos. I just said what i would do
@@NikosKalantasTouKabourdirhTouK ah, gotcha…. I’d just cut up the eg and make it lighter…definitely my favorite chassis
@@Serpentis666 it's got 4 doors and a/c and it's used as a daily/family car. Trying to find a 3 door eg (bone stock of course) in good condition to tune. It's really difficult
Is it's possible to swap the L15b7 cvt in a honda fitt?
Its a bolt on bro. Fit came from factory with L15b
I’ll stick to my l15 love it
L15 is max from factory aka it can't last long like K series. Every component is smaller from crank, bearing to piston.
Wait So my 2016 Civic Lx 6speed has a k20/24 in it ?!?!?!
No
@@julduke4605 what do I have them?
@@RealH4Xz L series engine
@@julduke4605 but I have a 2.0 l4 tho
@@RealH4Xz well I'll be damned. It is a k20. Although i think it's an economy version
Why is nobody talking about the poor design quality of the l series engine as a whole. There are major oiling issues, issues with the connecting rods, the crank, head bolts are weak causing them to be prone to the cylinder head lifting at high rpm. The list goes on. People should absolutely stay away from the l series engine.
Do you personally have one that has been extensively modified or are you just talking to talk lmao. Only thing I can agree with you on is headstuds. Lmao get off stock turbo trying to make 350ft pounds of torque at 2k rpm
@@Candybuiltsiruclips.net/video/ZriQAEfJ6RY/видео.htmlsi=jv5aoOw6Y1tGvwEZ
Cope because you could only afford the base model 💀
L15 is garbage. Keeping it stock is the only way to guarantee reliability.
The only issue with the engine is the head bolts lol that’s it
well at the same horsepower the L series is gonna put out way more torque
Sellimg my 10gen Si for a 8th gen Si say it all
it’s not as purty tho🫢
H all the way,true long block 🏋🏽♂️ finna do something💸 special💰for Vivian 🐌. Proud 3rd gen Prelude owner 😎.
I know that putting more than 200hp on a FWd is incredibly stupid.. but why cant i stop watching this high ho l15 builds lol
it was distracting how noticeable baked he is lol
More like baked with knowledge on these two engines!
@@maperformance Hahah. high on life, i love it!
Yall some babies! My wife drives a 19' accord sport with a k20 and manuel at that. Same trans as type R. Apparently only 1200 made before they quit making manuel accords all together. (the way God intended it) and we now have to settle for punns who think dual clutch DSG is the same without a physical clutch? (I drive a 06' tsx with 6 speed... k24) Please, son... I know they can shift faster and make slow cars seem faster than they are... But there is no better in-tunement with a vehicle than being in total charge... ask somebody!
The Boosted Boiz have shown multiple examples about what you can milk out of the best of the K series by spending enough money and breaking enough things but, like most such vehicles, they’re crude, high strung, constantly failing, very boy racer, and not realistic street cars. An 11th gen Civic is a MUCH more grown up and refined vehicle even when tuned into the 400+ horsepower territory. You get new styling, lots of new tech, comfort, safety, etc. with still about as much power as the front wheels can handle on realistic street tires at anything close to legal speeds. In other words any FWD street Civic on street tires is going to be largely traction limited under triple digit speeds even with “only” 400hp. So unless you want a drag or track car, why crank the power even higher when it’s so easy and cheap to get the L15B7 to make 300hp without replacing anything and 400+ hp with just a couple of bolt ons. Or try getting 300 hp from any stock NA K series without replacing anything. You can’t. A 400+ hp L15B7 can even still pass emissions tests where that’s required with all the stock tech still working and it won’t attract every cop within miles. A 2022 Civic Touring Sport hatch can be a very comfortable daily driver and 400+ hp sleeper for minimal dollars and hassle. And it will have far better resale than some older much more heavily modified K series Civic. Look at K20z3allmotor aka eman’s channel for his tear down on his stock internals 400+ wheel horsepower L15B7 never opened up with 25K of daily driving in a 10th gen Civic with zero problems and zero visible wear. That’s having your cake and eating it too. Yeah you’re not going to make 1000hp with an L15 but how practical is a Civic with more than 400 hp on the street? No matter how strong the K series is the tires, transmission, and rest of the drivetrain, are often the limiting factors. A few dyno pulls, or drag strip runs, is not the real world unless that’s all you care about.
Great perspective. You don’t think the turbo & GDI are going to be a problem for the L15?
Why does it seem like your opinion is more biased towards new platform?
You dont think the new models components will fail at the whp you claimed? I also have yet to see an FK7 or any other lower trim model from Si to make 400 hp. I also have yet to see an 11th gen make 400hp 😂. There are several weak spots on the 10th & 11th gen that basically share the same platform.
@@kdotldotsdot3430top end yes, handling and out of corner torque i dont think so
Yea no you are just asking for problems especially from a new car. ruclips.net/video/ZriQAEfJ6RY/видео.htmlsi=jv5aoOw6Y1tGvwEZ
damn that dyno chart at 5:05. that turbo lazy as heck.
True
damn these engines can make 500whp on a stock bottom end? lemme find out
my stock dc5 is way better than my stock fg2.
K series all the time. Ever see the l15 rod bolts. 🤣
Honda drop the ball on the L15 engines, they are weaker then old D series honda engines.. Good for gas but not for performance.
any info on SMOG testing with an engine swap?
I would imagine as long as the motor and emissions system is OEM then you'd be fine.
Largely depends on the state your in. In California they are very strict
The l15 is the worst engine Honda ever made. It's literally trash
