Hi everyone ! 2021 corolla or 2021 civic what your opinion guys ? Thanks.
New I'd go with a Civic EX if it were a previous model year I'd go Corollla I just am not a fan of the styling in the latest generation Corolla. I wish they offered the 2.0 NA in the Civic hatchback if they did that would be my choice. It comes down to personal opinion.
Does the 2.0 Honda engine suffer from carbon built ?
@lorenc if you are talking about carbon buildup on the back of the intake valves, all the Honda engines are susceptible to it over time because they are direct injection-only engines so the back of the intake valves is not getting sprayed or cleaned like you would have with port injection (which the Toyota does have).
not sure, but according to wikipedia it isn't direct fuel injected so I doubt it.
Here is the engine in concern: https://en.wikipedia.org/wiki/Honda_K_engine#K20C
engine: K20C2
@daywalker is good with these kind of searches he can double check me hopefully.
You could always ask this as another question to get more answers as well.
@daywalker
I knew you would comment! But just to be clear the K20C2 motor does NOT have direct fuel engine, according to wikipedia.
It is direct injection. I usually have to cross-check with what Wikipedia says because they have made mistakes before. See here and scroll down:

Hmm, Wikipedia was like "all direct injected excluding K20C2" so thanks WIkipedia for misleading me I will take DayWalker's word for it on this one, assuming the site is trustworthy.
Wiki can be edited by almost anybody. I have also seen my fair share of misinformation on there too.
@mountainmanjoe
What do you think about this site?
https://www.motorreviewer.com/engine.php?engine_id=163
Also it says its both direct injected and multi port injected so @daywalker would this also be susceptible to carbon buildup with both injection methods?
the article says the K20C2 specifically is GDI. Maybe the OTHER K20C's were not.
"The K20C2 version is a 2.0-liter naturally aspirated ... employs direct-injection technology and the Atkinson cycle ..."
I think I'm loosing it today Day Walker does research much quicker and much more precise/accurate than I do he can take over this comment section for today lol
@kerem those engines specs refer to the general K20 family (K20A, K20C, K20Z), so for fuel system they didn’t distinguish which of those engines had multi-point fuel injection (port injection) or direct injection. But the K20A and K20Z series engines are older engines going back 10 to 20+ years and had only port injection. The K20C series is newer and goes back to 2015 (or so), and to meet CAFE and other regulations switched to direct injection. Logically, It would be hard for me to believe that by MY 2021 (which OP is looking at) that Honda is still using port injection-only in one engine. It makes more sense to have DI in their whole lineup. And to my knowledge they don’t have DI+port injection like Toyota. They chose to go the DI-only route.
thank you
we get this question a lot, so try the search box.
Basic gist: whatever you like more. Check both out, sit in them, test drive them around.
A lot of the Toyota Corollas still come with a NA engine whereas the Honda Civics have more offerings that are turbo charged (some trims have NA still of course). Also, the engine in the Corolla still has port injection whereas on the Civic it is direct-injection only and therefore susceptible to carbon buildup on the back of the intake valves over time. A turbo charged GDI Honda Civic won’t last as long as a NA Toyota Corolla (which still has port injection) - but that’s for longevity. If you don’t plan to keep the car until the wheels fall off then it’s not as critical, but still another maintenance item (or two actually) that you have to at least be aware of and plan accordingly.
thanks
For Civic, I’d just go with the LX, Sportx or EX trim levels but stay away from the EX-T or EXL since those have the turbos that are known for oil dilution problems. But if you only plan to keep the car for 5-8 years or up to 120k miles, it doesn’t really matter
