K20C4 Engine Swapped Civic Si Gets Dyno Tuned 

This build is more important than a lot of people know. When people do these builds, they are paving the way for us in the future with these 10th and 11th gen Si’s. Thank you so much for sharing your journey.

All that hard work paid off man! The 2.0t sounds way better than the L15! Makes me want to k swap my FK7 😂.

also a full breakdown of what you need to compete this swap on the 10thgen si would be much appreciated!

You’re the man bro. I wish i knew how to tear down a engine and fully swap something like this. Seems like alot. But you definitely give some inspiration

Hell yeah!!!! Healthy numbers man, it is so awesome to see you finally pull this off.. well deserved.

hey, just fyi...Andy Cline has a set of cams from skunk 2. it's for the k20c4. it's a pre-production set and he's yet to pop them in the motor and use them! So...we're all just waiting...

Man, nice build! A k20c4 si! 👍🏽👍🏽👍🏽

So happy to see this especially from a development standpoint. I want this for my car someday but from a reliability standpoint over a power standpoint. As u said I wanna be able to beat on this car without worrying

What a marvelous build! I plan on trading in my 10th gen civic sport sedan for an SI in a couple years and this series has inspired me to get into modding! Might even do the same swap in the future, keep up the good work!

Now I want to do this with a coupe

Nice build bro! 384whp is plenty for a light car. I agree Drob is the best tuner for this platform, I will be tuning my car this coming week with him hopefully everything goes as planned.

Where were you getting the e85. I don’t know too many local stations that have it. The steering wheel is nice too.

+1 for Drob, he tuned my Si as well. L15 with 27won W2 Turbo and vp racing speed sauce. Car runs great! Awesome guy to work with. I already had plans to kswap if I blow the L15. I've been following your build for some time on and off, so definitely something I'll be looking into for the future of my car. Well done to everyone involved.

I like the idea, from outside it looks like another riced out shitty civic with a big wing, but inside it has almost 400whp and lots of torque... great build!

Hey what’s up bro , where can I get the swap done at?

Subbed 🙌

I know its maybe a little late now since you finished your build, but, the ecu for the 11th gen Si can control VTEC. So, could someone in theory, use the 11th gen si ECU to actuate VTEC on K20?

You got a short shifter or nah

Mashallah brother Inshallah the car lives a long and healthy life.

W vid !

Good stuff, my deceased Si had a built block that was going to go in, but eventually the plan was to go with a K20C. Though the built block and Pfitzner gear set never went in as some lady decided I didn’t exist and hit me from behind doing at least 50 with zero braking on her part. A K20C did happen though, this was ‘21, I don’t typically buy used because most people suck, but found a low mileage ‘20 Accord Sport 25 miles from me. Called the dude, said want to see it, was about to buy a ‘22 RDX ASpec, what I was planning to buy in October of ‘19 when moving back to the US after being away for a bit over 26 years. This is dragging on, haha, but I bought the Si, because the FK8 looked pretty bad to me and I wasn’t excited about having an auto travesty, the Si coupe reminded me somewhat of my very first new car a DC5R Teggy (looks only). Anyways, got the Accord, probably should have bought it initially, but didn’t even know they existed, the 10th gen wasn’t even sold in Japan, later one was but in hybrid form only. Hope all the troubles you went through to get to this point are a very distant memory and the newfound power brings nothing but smiles for you. Just came across you, think because you either showed up as a suggestion on IG or someone I follow there highlighted you.

The GOAT now get a 2024 Type S :3

wtf bro jumped frm 39-60😭

No tachometer ?

i want to try this swap

Yo bro next time u need Honda part lmk I live in New York and work at the dealer can get u oem for my price

A lot of racing soon👀👀👀

Try to retune with MT Tuned (Manolito). I think you hit 400 like mine accord on CTR turbo

what'd you gap your spark plugs to?

🎉

Does ac and everything work? Looks like you have no dash lights on either!

id kill for a pork roll egg n cheese rn🥺

Did you ever find out the problem with the gas pedal?

what about us 11th gen owner!? :o

only took 5 hours to upload 🙏

My 02 sensor socket made the video 👀 1:40

L15 only blow up around 500 hp on stock block from what's been seen. 350+ hp you'll start bend rods if your running too hot. i have a 290hp L15 CVT and I've been doing completely fine, i just do my maintenance like normal. ppl say cvt is shit for power but i disagree. sure is bad for 350+ but why would you even want to go any further than that on a L15. your better off getting a type r. like i said going past 350hp youll start braking stuff.

That wings gotta go
