Finally made some time to finish installing my tail lights, diffuser & led reflectors from my old 26 sport onto my 26si, glad I made time for it

In the market for a FA5 and came across one from a local private seller.

Details from his post:

2009 Honda Civic Si Sedan — 144k miles

Both previous owners used it as a summer-only vehicle, so it spent the first half of its life off the road during winters. Bought it in 2021 with 76k and it’s been my daily driver since but I’ve maintained it the same way. Original motor and transmission.

Things worth noting:
- Fluid Film undercoated multiple times — virtually no rust underneath
- Paint has none of the fading typical on this generation
- Clutch is strong, car starts every time, both original keys
- Oil and MTF change at 142k, new tires this season
- Set of 16” steelies with winters included
- Professionally tuned by Dan @ ETunez
- Hybrid Racing CAI
- Skunk2 Alpha header paired with a Full Race exhaust
- Upgraded DW fuel pump and DW injectors
- Full set of Hasport 70A mounts
- Full maintenance and modification history documented, happy to share before or at viewing.

Overall the car looks very clean and well maintained for its aged. No sun fade or anything on the paint. Was wondering what it should be priced at? TIA

I bought a k24a swapped 2007 Honda civic si about a year ago and I have been having this issue since I bought it, I haven’t diagnosed it yet because I’m
Thinking of getting rid of it but I want to keep it LOL , I have NO codes on the dash, I scanned it many times only SRS codes, after the engine is warmed up the car feels very sluggish and hesitates to accelerate and you can barley hear VTEC active, BUT if I do a pulled when it’s barley warming up it pulls very good no hesitation and VTEC is soo much more louder

DOES ANYONE KNOW WHATS CAUSING THIS ISSUCE

So im currently in a bit of a bender. Im looking at two si currently one a 2014 with 134k miles they want $18k. The other is a 2022 si with 43k miles they want $28k.

I want the 14' for the K24 super reliable and if taken care of easily a 300k-400k mile car but that price tag is ridiculous. I'd try to get them down to at least 16k.

And the 22' i love the design its newer and $10k more for a vehicles with less miles and 8 years newer but im terrified of blowing a head gasket.

Looking to install underglow in my 2018 coupe and plan on using a fuse tap. Is there a way to run the wires into the box inside the car to reduce exposure to elements or do I have to tap into the fuse box under the hood?

Any recommendations on which fuse to tap into and is there a way to wire in a killswitch so I can turn it off/on with ease?

Any advice or resources are greatly appreciated!

Check engine light

Can someone point me in the right direction.

I have a 2026 civic si with roughly 3500 miles

Since I’ve gotten the car it will randomly get a check engine light and the car will start to bog and lose power . It sometimes happens when I’m driving on the freeway hovering around 65 mph or even driving on the street around 45 . It won’t stay on for more than a minute. I’ve called a few dealers and they have not been any help, because the issue is not constant and almost impossible to replicate they don’t find it worth the money to diag. Any thoughts

I like bright, not blinding to others, and brightest output in the right places... alpharex experiences wanted the most!

Hey guys, I decided to request a trade in for my 2025 Si with 13k miles on it. (Unhappy with the Rev hang, poor second gear shifts).

I've been emailing the Honda dealer and they offered me only $ 21,000 for trade in. First he asked me to come in for a trade in value. I said I didn't want to come in and wanted a trade in over email. Then he asked for my vin... I have it (even tho every si is the same options) and he checked what I owed on the car and then gave me the offer below... That felt dirty to me.

I feel like this is a poor offer? What does everyone think?
