What did we miss? What cars should we cover next?
11th gen!
Weak 4th gear, seems like a known issue on the forums. They tend to break when people turn up the boost and produce higher torque. The fact that the L15 makes a ton of low end torque exacerbates this problem. HPD makes beefed up gears that solve the issue though.
Beefing the 10th gen when upgrading a turbo for reliability when trying to reach the 300+/- hp mark
Type-R?
Head lift
The fact you started with " when you start to modify " is the best part. As a Honda Tech I have a 18 Si and drive it hard, all the points you brought up are spot on. These cars are so fun to drive stock but when you do add power you have to support it with upgraded parts, you could also add switching to Head studs instead of the stock hardware for a better clamping force when pushing more boost. Some people think these things are like the old days where you can just start cranking it up, nope, you got to be careful. .
Weak clutch: sadly, the only solution is to get a better one
Oil dilution: happens to every DI gasoline car. Drive the car further and let it warm up, short drives where the engine doesn't fully get up to temp will exacerbate this tendency.
Carbon buildup: again, let the engine get up to operating temps and floor it regularly. According to VW, Subaru, BMW among other forums, carbon buildup isn't as big of an issue if the car's driven hard even semi regularly.
The Honda 6 speeds also have an issue with weak gears (moreso 4th gear), and HPD makes a beefed up gearset for higher power applications.
Would adjusting the spark plug gap size to ignite at sooner intervals help with the oil dilluution ?
Floor it regularly to help with carbon build up? Say no more!🤣
@@jewberg7729 no, the combustion cycle has nothing to do with oil dilution. It's everything to do with fuel condensing on the cylinder walls when it isn't at operating temperature, hence why cars with the L15 turbos that get driven very short distances have this issue.
@@jesspeachie yes, you want the valves to get hot enough to burn away that carbon. Mazda actually did a study on this and designed the coolant passages in their Skyactiv cylinder heads to not be as close to the intake valves so that they get hot enough to help negate carbon buildup.
@@turdferguson7438 the intake valves ARE the valves that get carboned up
MAP performance thank you for this video. I’ve been taking my 10th gen in for about 2months now. I’ve been having a loss in power through 1-2 a lil off the start in 3 as well. I’m like wth can it be, I’m noob, so imma check my spark and if there’s excess carbon it’s prob time for carbon build up maintenance, I hope that’s my problem! Thanks MAP we love 10th gen videos
I think the oil pump gear is the most overlooked upgrade in the 10th gen Civic. MAPerformance is spot on about the stock one breaking.
Update as of now. I have a 2017 civic si coupe with 69k (nice) miles on it. Ive kept constant check on my oil status by giving the dip stick a whiff everytime I check it just to make sure the gas smell isnt too strong. I get my oil changed every 3k miles or so to feel better about it. Oil changes are pretty cheap anyway so it would benefit to treat the engine to fresh oil as often as possible. Since it seems the fuel blowby issue is most common when the engine is cold, as of july last year I have started using at least 5w-20 in the engine to try to protect those cold starts since fuel can thin the oil out overtime. The car itself has been driven pretty dang hard throughout its life. It was tuned running Hondatas 9+ ots tune since as early as 8k miles. The clutch died at 15k. And has been thru 3 sets of tires already. The car has long since been put on a more powerful tune and improved with several bolt ons. Before I hit 60k i felt like the cars fuel economy was suffering so I changed the spark plugs at 60k miles and was shocked to notice my fuel economy return. Up to 43 mpg on my longest trips. The car has no odd smells or noises or any sign of leaks or odd behavior. I have also hit several deer in this car and suffered only from body damages. Car still drives like it was born yesterday. Heres to the next 70k miles 🍸
Meant to add that yes the car has been tuned the whole time running up to 25lbs of boost with full throttle shifting enabled for the last 30k miles with no hiccups, no cooling issues and no knocks.
They are the most reliable turbo car on the market rn
lol several deer 🦌
Stock turbo with 25 lbs boost tune?
Tuned and Just hit 30k miles on my SI and I love it
Th only thing I would like to add on are fuel injectors and head studs stretching (head gaskets) are prone to be problems on the L15s
Thank you for the tips!! I’m subscribed!
Nearly 18 thousand miles with my 18 Civic SI, no issues, aside from some weak AC. Looks like I'll need some recharge of the AC unit. Easy enough.
No carbon build-up, always take long drives enough to warm up the engine, wait a little bit to cool off the turbo after driving, always doing the required maintenance. Car is good.
Keep taking care of it and it will take care of you!
This Civic generation is known to have failing AC condensers. Luckily, there's a Honda service bulletin for it so definitely bring it up when you take it to the dealer. Shouldn't have to pay a cent. I've had to replace the condenser on my 17 si 3 times already.
My 18 SI had weak AC as well. No leak detected, after bringing it in the 4th time for a recharge they found leaking at the compressor. Wanted to charge me for the repair ~2k but ended up getting it covered. The service bulletin doesn't cover the compressor unfortunately
Nice but 18k miles is nothing, still brand new essentially
If you have not received the letter, the A/C system is now warranted for 10 years.
Excellent, entertaining, informative video. Thanks youse guys.
Glad you enjoyed it!
I have a 2019 si in red and I love my car . I can’t wait to finish paying it off in a few years so I can start upgrading it
Salute! Now i can do maintenance on my si by myself 🫡
MAN I wish I could find someone local to Littleton, Colorado that actually KNOWS these cars like you guys!! SOOO friggin hard to find good help these days! 😉😉
Edge Autosports is right in your area. Don't know them?? They on Iliff I think.
Thanks man’s 🙏🏼🙏🏼🙏🏼
Looking at getting into a 2020 Si! 🔥
YOU GUYS ARE AWSOME
Thanks for info i just bought a 2021 honda civic sport hatchback i was looking mod it
What would be the max reliable crank HP for the stock turbo?
I've been using crc intake valve cleaner since new. I use it right before an oil change. I also change the oil every 3500 miles. Not sure how much it matters on the L15B7 but a catch can might help? Also make sure folks are keeping an eye on their pcv valve too.
Thank you.
Any word on those fueling system upgrades you guys had hinted at a while back?
Your saying the passenger side of my motor is knocking because honda flawless design getting gas in my oil.. would a catch can help that last longer ?
If it's cheap and fast, chances are - it's not reliable. I have learned THE HARD WAY. Head gasket, ARP studs, front mount intercooler, clutch, and now injectors due to random misfires on 1 and 3. If I have one more MAJOR problem, my Si will be going BYE BYE. "Not a good way to spend $10,000". I should have gotten a Type R and went with a higher monthly payment....
I just bought a used 2020 Honda Civic Si as a daily driver. No plans to mod or tune at this point. Anything I have to worry about now or in the future since I’m not adding power?
What is the best brand aftermarket motor mount
When will the 10th Gen Civic Si Big turbo kit coming out or is it coming out? I Remember you guys saying it will be out soon 2 yeqrs ago and we'll it isn't out
My 2017 EX-T w. 102k miles has only 25mpg… is that normal? Changed spark plugs & cleaned MAF sensor w. no progress.
Does this break down apply for the 11’gen si as well?
Did you guys do one for the Subaru FA20DIT yet? Would like to hear your input on your wrx build and such.
We have not done one yet, it's definitely on the list though!
Whats the recommended gap on the spark plugs for a stock 2.0na on the 11th gen sedan
Would the same si performance clutch fit the 10thgen 1.5T accord ?
Keepin' my FC Stock, making the EK a drag racer
My 19 Si ive had alot of problems with overboost and i actually had my first misfire the other day original spark plus 76k miles ez change. but with the overboost all ive done to my car intake and intercooler. i have it flash tunes but its the stock tune flash with just the rev hang tuned off. why am i getting overboost code? Also how many miles do you think this carbon build up will actually start to take a noticable effect on the engine. 10th over 11th biased opinion haha awesome video
Great Vlog
What is max / safe PSI boost for a stock L15b7 please ?
Right! High boost pressures? What does that mean? 19.5? 21.5? 23? more? I'm not looking to drag race or anything, but if I get a ktuner and bump it up to 19.5 regular and 23 in sport, is that high?
2017 si sedan 120,000kms other than my injectors shit the bed she has been solid
There are plenty out there with over 200k miles. I don't think oil dilution or carbon buildup are a problem with this engine.
It happened to my 18 sport at 85k
@@litovvhghh which one??
60k miles on my 2020 fc1, I had the phearable 1.5/1.5r tune and intake since 2k miles on the stock clutch with no slippage to this day. We'll see if it still holds with a downpipe/intercooler. Honda should've just put the type-r clutch in this car from the factory.
Did you start slipping? I’m at the same mileage and stock clutch. Just ordered a Ktuner.
More tangents about being plugged up with carbon please
helpful video thank you. You were a little vague though. Like what service interval should plugs be replaced at? When you say over spinning the factory turbo you don't mention what boost pressure you are talking. the its tunes range from 20 to 29 psi from what i've seen. How much is too much? What exactly was teh fix the honda does to address oil dilution?
+8 is typically the pushing point, anything over +6 long term is going to hurt it
What chemical would you use to run through the intake for the carbon build up?
I would like to know too
www.bgprod.com/catalog/gasoline-fuel-system/bg-gdi-intake-valve-cleaner/
This is what our guys recommend!
@@maperformance really? Our sales rep at work for bg says not to use it on turbocharged cars
Nice Prius V 👌
How do we clean in carbon buildup?
I used to have a mk6 gti so seeing the carbon build up was like seeing a familiar friend 🤣
Y’all ain’t Bafoons man y’all gods to me 😭
Thank you for your support!
For the oil dilution how often do u recommend oil changes to be on the safe side ? Every 2 k miles ?
3k
5k
I think it really depends on your situation. If you normally drive 20-50 miles every time, you could likely stick with the guess-o-meter on the dash, but if your drives are very short then you risk dealing with fuel dilution and I would recommend 3-6k between changes.
My friend is a Honda mechanic and he recommends to change it once it gets to 50% life
I Daily drive mine about 60 miles a day and I do it every 3k or till it gets to 70%.
Not so much a maintenance issue but its worth mentioning that if you add power to these engines, you really should consider aftermarket head studs and head gasket.
Question... I have a mom's EXL and got a valve that got stuck clean it with some c foam got it working again but now I'm burning oil? Any ideas?
It's a 2016
Another question spraying a cleaner should it be sprayed right at the air filter past the air flow sensor. I talked with a Honda mechanic he said that's a long ways from the valves. Only place I have ever done it.
My ac stopped cooling, Honda fixed it, no questions asked on their dime. 19 6sp sp touring here.
Talk about suspension upgrades. Which suspension mods are best and at what cost.
tires, brakes, lowering springs/coilovers, beefy rear sway bar, front strut tower brace, probably in exactly that order is the best for these cars.
Good 👍 ASS job, keep it up PLEASE.. ✌.
I was with y'all until ya said 11th Gen is better looking than Gen X. Lol! Great video guys!
Totally agree!!! I see the 11th gen beside me on a stop light and never have a felt more proud of me switching to the 10th instead of waiting for that VW looking car hahaha
I mean it’s beautiful don’t get me wrong and it’ll definitely have it’s market, but seriously every time I see one from behind I can’t tell if it’s actually a civic or not until I can read the logo, you can spot a 10th gen from a mile away and I like that about my car
@@partypooper6982 Because 10th gen has all those random plastic vent looking things slapped on the back that look like Ebay aftermarket parts.
@@DB-mq4so ahahaha okay they are not THAT bad, hater🤣. But no it’s the whole style of the back end, in either sedan or hatch, and obviously the taillights are a major giveaway that that’s a 10th gen civic in front of you:)
For those of us, like your Mum, who own an exl and have some cash, what would you recommend for performance upgrades under $3000.00 as a kit?
I'm 56 and in my first modern honda , 2018 exl civic.
I have stepped out if my 420hp 2002 silverado.
Throttle response is a safety feature in my book. And I miss it!
3 grand....what parts?
I am all ears fellas!
Give us a call at 1-888-627-3736 and we would be happy to find some modifications within your budget!
Buy an si. For 3K if you trade it in you can probably get one. Big big difference overall
@@boblast8506 I’m with you can’t wait till my si is paid off I’m going for type r
Do you think a thicker oil could help with the dilution problem? I heard that this is more common in cold areas and the dilution lower in tropical zones.
Correct, that is a common fix for parts of the world that are hotter than others. Here in MN most "higher" HP builds run thicker oil in the summer and thinner in the winter (if they're driving in the winter).
@@maperformance thanks for the reply, good to know 👍🏽
I hope to buy a Si 10th Gen sometime and I would like to take it close to 240hp, is that possible with the OEM turbo?
@@kenneth2405 Yes with an OTS tune alone, you're up to like... 220.
Thoughts about the stock intercooler ?
if its anything like the 11th gen, its complete shit lmfao. highly recommend upgrading it.
@@TheAutoDistrict yeah the 10th gen intercooler heatsoaks pretty easily. Definitely needs an upgrade if you're going to be pushing the car.
2:59 reason why I went for a 20 corolla manny.
When do we get to see the update on the GR86 turbo?
Tuning is the holdup at the moment! Someone has to crack the ECU.
What can be done about the excess carbon?
Like mentioned at time signature 4:13 you can walnut blast and throw in some additives!
Will running Lucas gas additive help with carbon build up or running 93 octane shell gasoline ?
Since the fuel never hits the intake valves I don’t think any additive would help. The traditional mod that attempts to reduce carbon build up is a catch can. Other than that, you can simply wait till you start having a rough idle, then have them cleaned using a media blaster. Most dealerships can perform this.
@@ROBMACDUI Catch can doesn't do shit. Have a Mishmoto catch can on my 2018 si for over a year and not 1 drop of diluted oil was found in the can.
Can you do the integra next 🥰
It bugs me there is literally no info like this on the 10th gen 1.5t accord or aftermarket clutch options available as well
No point in modding it. Si 10th gen 1.5’s have forged internal from factory and are still weak. All other l15s are built with weaker internals
What the other commentator said. The L15B7 in the si are really the only strong power and modifiable version. I would say intake+ lower boost tune maybe exhaust if you want it. That’s as far as you’ll get but will still be peppy and fun
Any plans to do one of these vids for the Q60?
There's a possibility! We have tons of content in the mix.
nice build but that alu weld straight off the turbo needs to go, ill pay you to it at this point.
Don't forget PCV valve
I don't think you guys could be any less specific. Air intake and a tune.. uuhh.. what kind of tune? High boost pressures? What's high? 19.5? 23? more?
I hate how trash the oem clutch is, I mean you make a sports car that's boosted you'd could at least expect a clutch disk that can hold more than stock power levels, it's impossible to find anyone who does aftermarket clutches and I do understand the reasoning for that
Just test drove a used 2018 Si with 61k miles. It didn't look like it was abused, BUT the exhaust was black indicating it was burning oil. I also smelled the oil and it smelled like gasoline, indicating it has the dilution issue. Again, this car was 100% stock, so Honda lost some of it's quality going with a small 1.5l non vtec turbo engine....and that makes me sad. Still, was a fun test drive, but I passed right when I saw the issues.
Say! What about 1.5 turbo 2019 !
11gen exhaust looks better in the back definitely
what’s a safe amount of boost pressure on the Si? Because as of right now, I have a 2018 Si coupe and the mods that I have is a Ktuner pushing 21.5 psi with 22 psi at peak, MAPerformance Catted DP, Injen short ram intake, and MAPerformance exhaust. I was told pushing 22 psi is a bit too much on the stock turbo but I’ve also heard that 22 psi on the stock turbo isn’t that much but I don’t know which is the truth and what to believe so what’s a safe and reliable psi range to run? Someone help please
21-22 psi is about as much as you would want to push the stock turbo. We have seen up to 25-27 psi, but the life of the turbo is not long!
Cover the 11th gen SI
10th gen >
No way, 11th gen gets vtech on the exhaust valves and a twin scroll turbo, along with various type R parts such as the shifter and some suspension components. Only benefit to the 10th gen is you get heated seats, adaptive suspension, and way more storage compartments.
@@ROBMACDUI 11th gets rev match as well. 11th gen is missing all the fake plastic vent crap as well.
I have seen ex civics hatchback 10th gen beat 10gen civic SI,
Sometimes is not the car but the driver fact
But when are we gonna get better injectors for these cars 😪
HOLY SHITTT WATCH OUT FOR THE CAR BACKING UP BEHIND YOU, y’all ALL ALMOST GOT RUNNNN OVERRRRR!!!!!!
The rear end of the new civic looks just like a 10th gen Accord.
10th>11th. 11th only comes in a sedan.
11th gen does not come in hatchback? REALLY?
Which is why I got the integra 🥰
Yes it does?
@@jamesmedina2062yes it does it’s only the type r that’s a hatchback
No the touring does too
Or just move at a more robust platform like a vw gti 😎
Has anyone experienced having issues with the shim plate on the drivers side warping and hitting against the rotor? Makes the most annoying screeching noise when making a left turn 😡 had my boy who's a Honda mechanic fix it for me like 5 times already. Ended up buying new ones and the issue came right back lol.
I think I know what your talking about I thought it was cv axles. when ever I do a full u turn I hear it
@@OnlyAngel-ek6zy I thought it was the break pads at first but it ended up being that. My friend did his thing and it hasn't bent back ever since.
Honda knows it's a known issue from 18 to 20 but have no fix for it yet 🙃
Yes I’ve had this issue as well. Just have to keep replacing it or Mod it somehow.
I just keep pushing it back in with a flathead screwdriver when it begins to squeak. Usually goes away for a few hundred miles.
So you forgot about 1.5Ts blowing tons of head gaskets? Especially when run hi-performance. I drive a stock car, no goodies and drive it like a granny most of the time to get high MPG, and I had a blown head gasket. Mine is a 2018 EX-T sedan with 6 sp. manual.
From what I've seen, cheap head bolts. The fix? Aftermarket head bolts.
when are we going to get 11th gen videos
As soon as we get our hands on one!
@@maperformance Have you gotten one yet?!
T lx type S content
Unfortunately, we no longer have ours!
Does that mean no aftermarket support?
So in other words Buy a Normal Civic Sedan like my wife did a 2020 Sport Sedan with the K20C2 engine and 6 speed manual No carbon or Fuel dilution with this Car, Because it doesn't have GDI or a Turbo charger it simply doesn't NEED it if you Want a dependable car for getting to work 🤓.
Yes I like good information like this video provides 👍🤑.
The K20C2 is DI...
Yes that’s the more reliable thing to do. However modifying you wouldn’t get 1/10 as far with the k20c2.
@@boblast8506 I didn't buy this to modify it, It's built for Great fuel mileage and reliability, Driving it Conservativly setting Cruise at 62 mph has shown to do 45 MPG, If you stomp on the Gas all the time You'll be lucky to get 34 mpg using 87 octane gasoline, If I wanted a faster Civic I would buy the Type R.
11th gen is def where it’s at
Bruh what. It's the same platform other than the clutch and a static suspension.
It's literally a 10th gen Accord with a painted grille to match the body color
@@sonofulti1859 It "literally" is not an Accord, but a improved version of the 10th gen Civic
first lets goo
And for that, a high five. 👋
The 1.5l sucks why I bought a k20c2 with 6 speed you can swap the k20c1 head and hood to go but the 1.5 you have to swap all internals to make it reliable with power
Depends on what you are shooting for. Under 300hp and you’ll have no major issues minus swapping head bolts which can be done without removing the head. The K20 would require quite a bit more money to hit 250-280 than the 10th gen. Of course, the k20 would be able to get to higher numbers without replacing the bottom end but at that point I would think simply buying a more powerful factory vehicle makes a bit more financial sense.
@@ROBMACDUI you are talking about the k20A im talking about k20c bro before you cooment you should read the k20c2 can handle 500hp np also the k20a can also sound like you never worked on a honda before the l15 cant handle 300+ because the crank brakes
@@ROBMACDUI before you try to comment something again here some things about a k20c they have bigger sleeves better stock crank and Pistons they can handle alot of power and been proven check out the 400Hp 2017 civic on stock the guy just added a turbo k20a been proven it can hold more then 500HP stock but the k20c is better with power and more reilable the L15 is horable and brakes at 300HP
@@beargang8853 Geez man relax. I’m not questioning the ability to hold more power but for those that don’t feel like spending thousands on mods you can add 80hp and over 100lb ft of torque reliably with nothing more than a $500 tune. For most people that’s more than enough and makes the most sense given you can have a pretty potent sport compact on the cheap without destroying its resale value by throwing a bunch of aftermarket parts on it and ruining its daily driving comfort. If aiming for big hp numbers then Why even bother with a fwd car. You’ll never be able to put down much more than that without upsetting the chassis and ruining its handling which is the strong point of these cars.
@@ROBMACDUI naw you were saying how you know it cant hold power you got called out now. trying to say something else like i said don't comment if you don't know Honda Engines are the cheapest $ to power with Reliability anyway don't comment again till you work on one of these or have a question
I wouldn’t listen to any advice from someone running supertech oil.
Geez dont why i feel like this is going to be one of the worse engines honda has made..
11th gen is ugly
1.5 10th gen worst motor ever made this is why i bought a k20c still not the great but can be fixed
